Lifehack: How to pack two meters of chromatin into your cell’s nucleus, knot-free!
The entirety of our genetic information is encoded in our DNA. In our cells, it wraps together with proteins to form a flexible fiber about 2 metres long known as chromatin. Despite its length, each cell in our body keeps a copy of our chromatin in its nucleus, which is only about 10 microns across. For scale, if the nucleus was the size of a basketball, its chromatin would be about 90 miles long. How can it all fit in there? To make matters worse, the cell needs chromatin to be easily accessible for reading and copying, so it can’t be all tangled up. It’s not surprising then that scientists have been puzzled as to how this packing problem can be reliably solved in every cell. The solution is to pack the chromatin in a specific way, and research suggests that this may be in the form of a “fractal globule”.

How to turn off cancer cell growth using mechanosensing
Our bodies are made up of cells that can sense and respond to their dynamic environment. As an example, pancreatic beta cells chemically sense increased blood sugar concentrations and respond by producing insulin. Scientists have found that cells can also mechanically sense their environment; “mechanosensing” determines whether a cell should grow or die. Cancer is characterized by uncontrolled cellular growth, where cells often contain mutations that inhibit the natural mechanisms of cell death. Because mechanosensing is one such mechanism, scientists have hypothesized that cancer cells keep growing because they lack the ability to probe their environments. In this week’s paper, published in Nature Materials, an international research team led by Bo Yang and Michael Sheetz from the National University of Singapore investigated that hypothesis by combining tools from soft matter physics and biology.

Baromorphs: Shape Shifting by Inflating
Conventional robots typically move by moving rigid pieces relative to one another — think of a robotic hand where rigid bars rotate at joints. In other words, conventional robots have a small number of “degrees of freedom” — the angle of bending of the joint of a robot hand would be one degree of freedom, for example. Soft robots, on the other hand, have many degrees of freedom: they can bend and deform into lots of different configurations. )Because of this, they often display continuum-like behaviour, similar to what is seen in the movement of natural organisms such as worms and octopuses. These robots offer great promise in many fields, from soft instruments for minimally invasive surgery to shape changing airfoils for increased flight control. One of the particularly difficult challenges in soft robotics is to design systems that are flat at rest but can rapidly transform to an arbitrary three dimensional shape when activated. Recently, Emmanuel Siéfert and co-workers developed baromorphs— thin, flexible sheets which can be air inflated (“pneumatically activated”) into a pre-programmed target shape.
When you pull on a drop, how does it pull back?
Physicists like to ignore things. In some cases, we may neglect gravity or assume that the temperature is zero degrees Kelvin — colder than any known substance in the universe. And friction is almost comically absent in most models, despite the fact that a world without it would be utterly uninhabitable (this is nicely illustrated in cartoon form here:

Soft engines: Leidenfrost effect in elastic solids
Have you ever wondered why a water droplet rolls around on a hot pan instead of evaporating instantly? The part of the droplet touching the pan does indeed evaporate. The resulting vapor forms a thin insulating layer that enables the drop to hover over the pan for seconds, even minutes. This is known as the Leidenfrost effect. Because they also produce vapor when heated, sublimable solids (solids that skip over the liquid phase and directly produce vapor) also exhibit the Leidenfrost effect. This effect has been studied extensively for both liquids and sublimable solids.

An Introduction to Forensic Anthropology

"An Introduction to Forensic Anthropology"
Image by:
The television has fast become a window into the subject of forensics, sensationalizing the science involved when investigating a recently discovered corpse. This macabre subject was once left only to the police and scientists to examine and uncover the secrets behind the cover of closed doors, but now in this generation the camera's eye is firmly fixed upon this hidden world exposing it to us through the medium of reality television, or drama based shows like CSI and Bones.
What is Forensic Anthropology?
Forensic Anthropology is a scientific process of investigation that takes place on human remains that are either decomposed beyond recognition or devoid of any remaining DNA. Basically this role involves the investigation of skeletal remains. This form of investigation uses applied sciences from several areas to deduce possible cause of death, or physical characteristics, which may contribute to revealing the identity. With thorough investigative process we may reveal if a victim was hit with a sledgehammer, or if he was shot or stabbed, just by markings or impressions in our bones. Forensic anthropology is used to explore the remains to deduce this and many other things throughout the forensic investigation.
So what role does a Forensic Anthropologist play in both historical discovery, and modern day forensic investigation?
Archaeological Forensic Anthropology:
During the course of an archaeological discovery the dig site may uncover the decomposed remains of a human body. The Forensic Anthropologist will perform a series of investigative techniques to reveal the origin, race, gender, and other characteristics to better understand the people or culture that lived at this particular site. Sure, it sounds simple enough to make these assumptions, but they use a plethora of applied sciences to concretely uncover findings such as cause of death, genetic dispositions like disease or medical history.
Criminal Forensic Anthropology:
This modern day science is called upon during the course of an investigation in which the remains are in the form of skeletal, or have undergone decomposition or mutilation where only the bones remain. Forensic anthropology has two main roles to play over the course of an investigation; first we have the investigation itself, uncovering vital information to assist to solve whether a crime has occurred or not. The second role is found in the courtroom, where they may be called upon to give testimony as a specialist or Expert Witness, which reveals both technique implied, and expert opinions to support the investigation, either to benefit the defense, or the prosecution over the course of a trial. During the investigative process a forensic anthropologist performs a postmortem investigation (autopsy), to reveal characteristics to aid in identification, and possible cause of death if applicable.
Applied sciences used in conjunction with Forensic Anthropology include:
Physical Anthropology:
This science is the study of biological evolution, through transitional genetic traits, human adaptation, and primatology, and fossil record of human evolution. Most famed physical anthropologist included; Alfred Russel Wallace, Gregor Mendel, and Charles Darwin, famed for his work on his theory of natural selection. Like most forms of anthropology this subject occasionally implies other science, but its main focus is on the biological field of research.
Forensic Pathology:
This is basically the science behind the cause of death. A forensic pathologist uses physical postmortem investigation, and other evidence to uncover the true nature of the death of a victim being investigated. Using medical testing, and other tools they may reveal such things like, physical trauma, medical intervention, or natural occurring causes that led to the death.
Forensic Dentistry (Odontology):
Dental evidence can sometimes reveal many important pieces of information to help identify a body. Dental records are unique like fingerprints, and can be used to quickly identify a victim with the aid of dental impressions, which are compared to ante-mortem photographs or records.
Forensic Facial Reconstruction:
Although this form of evidence is usually dismissed for being inadmissible in a court of law, it still has had great success in the identification process. The simple description of this science is the recreation of the unidentified individual to determine the identity using only skeletal remains. There are three basic techniques used to perform a facial reconstruction.
* Two-dimensional, was the result of Karen T Taylor, which implies the use of hand-drawn facial images based on ante mortem photos, and the skull. This method can be used to match known missing victims to the recovered skull, but was a limited application until the use of computers and software programs.
* Three-dimensional reconstructions are commonly depicted on shows like CSI, and are much more compelling in nature. The three-dimensional impression or cast is created using modeling clay or other materials, which is applied to the cranial remains to form the shape or characteristics of the victim. Now with the aid of computer programs, this process can also make multiple images of characteristics like eye-color, hair type and color, along with other physical markers to assist in matching the victim.
* Superimposition is used along with other techniques of reconstruction. This is not the most common tool used during facial reconstruction, but by superimposing an image or photograph of a possible target of an identity linked to the unidentified skeletal remains, over-top of an X-ray image of the unidentified skull, this may prove a match based on specific anatomical features that will become aligned during the process.
When dealing with skeletal remains whether they are found on an archaeological dig, or during the course of an extensive murder investigation, discovering the identity becomes of the utmost importance. Homicide investigators and other Science departments rely upon the expertise of Forensic Anthropologists to uncover the unknown factors that may aid in revealing important things about the remains. Physical characteristics like age, gender, and race may rule out or reveal important details, while cause of death, medical history, and genetics, can filter out the possibility of an unnatural or natural death.
Although this evidence is usually subjected to the scrutiny of the legal system, in the world of science it is a reputable form of study, and has very few accredited specialists that harbor the coveted title. The American Academy of Forensic Sciences (AAFS) to date has nearly six thousand members that are part of ten separate divisions within the Forensic Studies, but barely a hundred or more are considered to be identifiable as forensic anthropologists.
In the science community there is a great deal of respect among their dedicated circles regarding forensic anthropology. These dedicated men and women devote their life work to unveiling the mystery that lies beneath our flesh and blood. They painstakingly use every available resource to uncover evidence to determine if an unidentified person's remains was only a life lived, or whether it was the victim to something more sinister. They also play a vital role in our own historical beginnings, using history and science to answer the questions that may otherwise remain unknown. As humans we have a great desire or curiosity to understand everything that lay before us, and with the aid of forensic anthropology we might just get closer to the answers!

Moving Forward (Assignment)
Scenario Concepts: We considered various scenarios and settings that would provide relevance with our target audience and referenced what we have been introduced to through the duration of the module. We examined several different concepts, before deciding on what would generate the most interest between our desired age category -
University / Societies - Building on the popularity of shows like Skins, The Inbetweeners and Hollyoaks but basing the theme on universities and societies.
Emergency Services - An alternative to Casualty, Scrubs, ER and London's Burning that incorporates every service.
Sailing Community - A glamorous setting that could be the UK alternative to The Hills.
Cartoon - This option would provide flexibility, creative freedom and unlimited boundaries to create any setting and culture.
Olympics - This would promote the games, athletics - what happens during the build up to games.
Rap Scene (East London) - Struggle for acceptance - pioneering a music scene.
We decided that the University / Societies setting was the most attractive concept for our target audience. This was because it would build on a genre that they would be familiar with and tackle issues that were important. We felt that the show should be UK based and provide an alternative perspective on how UK universities differ from their American counterpart. We also felt that through education we would be able to incorporate aspects of the other scenarios - studying to become a doctor; the athletics star working towards the Olympics; music production and attempting to make a break in the industry.
Title Semiotics: We choose the title Forward because the definition provided semiotics that we felt were relevant to our show.
As sign users we were able to identify many meanings that we felt were relevant. We applied the theory that Ferdinand de Saussure, a Swiss linguistic, introduced and founded for many significant developments in linguistics in the twentieth century.
A few examples from the free dictionary definition -
The notion of progress; being in front: moving towards a point
Being in front of trends: student protests being a political example
Deviating radically from convention or tradition: providing a different, possibly extreme approach to tackling issues
Moving in a prescribed direction: A clock and cassette are mentioned which we have referenced in our radio advert
Sports references which relate to the various sports played by societies
Promotion / Airplay: Ask some businesses about radio advertising and they will tell you it's the greatest investment they have ever made, while others will tell you it's a complete waste of time and money. We feel that radio isn't an ideal method of advertising a television show, especially when the radio commercial would be paired with multiple advertisements aiming to stand out! This meant that we needed to inspire and also extend the listening experience.
We wrote down a detailed description of our core audience and the potential time they would be listening to the radio.
As the advert would be aired on national syndicated radio, we decided on the 19:00 - 00:00 time slot.
We also wanted to extend the listening experience for our audience and make the radio advert more interactive. We opted for social media channels, they're easily accessible and provide scalable publishing techniques. This would provide additional content for the show and enable them to share with their network, thus raising exposure of the show.
Production: We used Cubase 4 which is music software, developed by Steinberg for music recording, arranging and editing as part of Digital Audio Workstation to produce the advert.
Music: The intro to the advert is Imagine (1971) by John Lennon, with lyrics 'you may say that I'm a dreamer, but I'm not the only one,' we felt that it signified aspirations and dreams about achievement. The lyrics mention not being the 'only one' which we felt related; being at university with others and working towards a better future. The chords for Imagine were later sampled by Oasis, in their track Don't Look Back In Anger (1996). The voices of my children accompanied the sample to imply childhood memories and not looking back in anger! The second sample is the Gives You Hell (2008) chords by All American Rejects, selected because the track implies rebellion and being given hell when being confronted!
Media Studies: We wanted to portray images of 'youth-as-trouble' and 'youth-as-fun' through the advert, suggested in wider reading material from Media studies: texts, institutions, and audiences. By Lisa Taylor and Andrew Willis.
Narratives: The voices provide the dreams of a child and the struggles of a teenager trying to make the right choices.
Movie References: We referenced movie dialogue throughout the script that would be instantly recognisable within the advert. These were the movies Fight Club (1999) and Trainspotting (1996), the repetition providing the listener with choices.
Sound Effects: We added cassette fast forward and vinyl fade out sound effects. Both being retro and iconic from youth, and Forward being the name of the show also influenced this decision!

The centrifuge For the first time, a British engineer named Benjamin Robbins had created a rotating armpit to identify drugs. In 1879, Anthony Pringles used the first centrifuges for milk to be separated from the cream. In 1879, a person called Gathat showed that centrifuges could be used for business purposes. Different dimensions of centrifuges have been expanded and can be evaluated in a range of functions from 1 ml to 1 liter.
The image is from a centrifuge belonging to the 19th Century that spins around.
Attention to micro-centrifuges was developed by a German company in 1962, and the company used micro-polymer systems for laboratory use.
Principles of centrifuge
If the centrifuge particles in a sample have different masses, they can be separated from each other based on the difference in mass and the effect of their gravity. To accelerate this, a method called centrifuge or ointment is used. The central core of the centrifuge is the centrifugal principle, which is one of the principles of the physics of the era.
In fact, centrifugal separation by centrifugal force separates the suspension from the liquid. It can also cause the separation of two liquid with different densities. These fluids can be body fluids (such as blood, serum, and urine).
By centrifuging the force of gravity several times, it increases the natural rate of separation of particles with different densities.
At a glance, the centrifuge is a metal flywheel with holes in which the specimens are intended and a motor that rotates at a selected speed.
What is centrifuge
A centrifuge or centrifugal device is a device that separates materials from the center of the centrifugal force. The enclosure, in which the detachable material is located, is usually used with the help of a motor speeding around a rotating axis for rotating the material at a high speed. Scientists usually use a centrifuge device to separate solids from a liquid or to split liquids into various components.
The mixture is placed in a tube so that the device moves outward from the center and rotate to the horizontal. In this case, the centrifugal force wants to remove the mixture, in contrast to the center of the centrifuge, and away from this point. In this case, the heavier particles or heavier fluid is further driven outward (or substrate). When the centrifuge stops moving, the material remains unconsolidated. Blood and other biological samples are usually isolated by centrifugal machines
Different types of centrifugal devices are made for various uses. Household samples are used to separate water from vegetables such as lettuce and so on. Plasma samples are used to remove blood globulins. Industrial machines are powered by robust and large-sized engines for separating materials. The uranium enrichment plant also uses gas centrifuge devices
Centrifuge division according to the speed of rotation
1 centrifuge with high speed
2 centrifuges with low speed
3 ultrasonic centrifuges
High-end centrifuges
The round circumference is between rpm24000-21000 and a maximum rpm of 30000. High-speed centrifuges are used for most products. All are refrigerated.
There are two types of high-end centrifuges: low capacity and high capacity.
Low-capacity centrifuge: With discrete sampling, it can isolate microorganisms, cells, viruses and cellular organs.
High-density centrifuge: A continuous model for obtaining yeast and bacteria from the culture medium, the protein from the specimens and the virus and bacteriophage from the diluted specimens. (2)
Downstream centrifuges
Its round ranges range from 2000 to 6000 rpm with a maximum of 8000 rpm in both refrigerated and non-refrigerated form. More often, centrifugation of blood cells or bulk particles is not enough and it is not enough to separate fine particles.
Ultrasound Centrifuges
The ultra rpm is 100,000-75,000 with a maximum of 120,000 rpm. They are used to differentiate cellular ingredients. All have a refrigerator. Because during the high friction period (1), the air causes the device to heat up and thus destroy the proteins. Ultras are commonly used in research centers.
Properties of centrifuges based on their rotation: (Table 1)
Properties Ultra Centrifuge Above Far down
Speed (rpm * 1000) 120-75 30-21 8-2
Refrigerator Everyone Everyone Some models
Vacuum system Everyone Some models No
accelerator mostly mostly Some
In the division, the other centrifuges are divided into three types of floating, fixed and axial angles:
Floating centrifuges:
In this type of centrifuge, in the state of the vertical stop, and in the period of time, the samples have a horizontal position with the ground.
In this type of centrifuge, suspended particles are driven by the influence of the centrifugal force on the external part, the end of the tubes and the deposit is formed as an almost uniform layer at the bottom of the tube. At the end of the operation, the tubes containing the sample are restored to the vertical, depositing at the bottom of the tube and a clear solution above it.
Fixed angle centrifuges:
In this type of centrifuge, the tube contains a sample relative to the axis of a one-dimensional angle. This angle can vary from 25 to 45 degrees, and the suspended particles are driven by the centrifugal force to the outside of the axis, but, unlike centrifuges, the sediment floats are driven in the wall and in the part of the pipe bottom located on the outer side of the axis of the rotation. To be
Of course, as this angle is less in relation to the axis of the period, the precipitate is more in the wall, and if the angle is greater, the sediment is more concentrated in the floor.
The rotor shape of this type of centrifuge allows for a longer period of time and deposition of smaller particles. Therefore, the sedimentation rate of this type of float is higher.
If you want to use a floating point like a fixed angle, then the higher the temperature, the higher the friction with air, the temperature will increase.
Axial centrifuges:
In principle, the sample tube runs along its vertical axis (unlike ordinary centrifuges that run along the horizontal axis) .
Application of different types of centrifuges: (Table 2)
Isolation / Type Ultra Centrifuge Above Far down
The cell Yes Yes Yes
Sediment Everyone mostly Some
Membrane parts Everyone Some No
Ribosomal-poly-zoom Everyone Some No
Macromolecule Everyone Some No
Components of the centrifuge machine:
1. Motor (pump) 2. Rotor 3. Refrigerator 4. Control system 5. Device compartment
Rotor: centrifuge
A typical centrifuge has a chamber called a rotor or head that works with the engine. Rotors have different types, but the types that are commonly used in laboratories are divided into two categories: the first group of rotors in which the tube contains a solid-liquid at a constant angle and therefore they are rotors Say with a fixed angle. The second group is the ones in which the tubes are located in metal chambers and are rotatably rotated externally and horizontally so that the fluid and the suspended material inside the pipes are exposed to centrifugal force. This rotor The rotors are called with a hanging compartment.
When the body rotates, technically, the centroidal force forces the object to move in a circular path with a constant radius, which forces the body to rotate to the center of the circle continuously. When the speed is constant, this force only causes the change On the other hand, the body is pulled by a force called the center of gravity, in front of the direction of movement, which is equal to the centroidal force and causes the body to move away from the curve of the circle of rotation in a straight and tangential direction. On the circle
The rotor specifications for different centrifuge methods are presented in Table 3
Rotor type Isopicric regional Sedimentation Differentiation
Fixed angle Good Weak Excellent
Vertical Good Good Weak
Floating Enough Good inefficient
zonal Enough Excellent Weak
Application of Centrifuge
In the sweetening of the highly concentrated syrup, the masonite consists of two solid parts (sugar crystals) and a liquid (non-crystalline section), which in turn is separated from each other by centrifugation. The sugar crystals are washed and then high-purity sugar is produced.
So the water of this section, due to its significant amounts of sugar, is crystallized in several steps, eventually, the water, which can no longer be obtained from the crystal, is removed as molasses from the factory. In some factories, the molasses go to the molasses sugar mill and are recycled with molasses sugar powdered lime powder. In factories that produce sugar, centrifuges are used to convert sugar into sugar
There are centrifuges in all of the parts that need to be isolated, and another example is its use in the food industry in dairy factories.
• In the starching industry, coloring, knitting for the drying of chemical chemicals, clothing and so on.
• Centrifuges can also be used to control air pollution at the site of production.
Types of centrifuges used in active sewage and sludge sources
1-centrifugal solid bowl (cylindrical)
2-Centrifugal Baskets (Perforated Basket, Basket Without Hole)
3rd Centrifuge Disc
Centrifugal cylindrical
Cylindrical centrifugal (tube bowl) is one of the important types that can easily produce a lot of centrifugal force. Cylindrical centrifuges can be cooled, which is an advantage in working with proteins.
In this type of suspension, centrifuge it usually enters the end of the tube and the transparent liquid is removed from the top. The solids in the solution form as a thick paste layer on the wall of the tube until it can be seen at the outlet of the solid. Injection continued, then shut off and finish the centrifuge. This interruption in operation is a major issue
The residence time of a liquid in a cylindrical centrifuge
Main cylindrical centrifugal equation (inlet feed)
The sedimentation centrifuge rate is only a function of particles and is independent of the specific centrifuges, but the amount in the bracket that is too long does not function as a particle and depends only on the type of centrifuge.
Filtering radiographs and their design equations
Centrifuge filter (Centrifugal filter)
• These filters are divided into two general types of continuous and discontinuous. Usually, these filters are used for solids that form a porous mold. To do this, the slurry is inserted into a rotating basket that has a grooved or lattice wall, or the filtering environment is covered with cloth or metal nets.
Types of Filtering Centrifuges
• Discontinuous filtering
• Continuous Filtering Centrifugation

737315 Integrated socioecological modelling
Lecture and seminar
Semester hours
Lecturer (assistant)
Gaube, Veronika , Haberl, Helmut
Offered in
Wintersemester 2021/22
Languages of instruction
Models are simplified representations of complex phenomena. They help to better understand interrelations in complex systems, to reconstruct past system states based on incomplete data, to create forecasts or scenarios of future developments and to structure communication processes. In the seminar, we will discuss computer models that simulate the interactions between social dynamics and their biophysical effects on essential ecological patterns and processes. A variety of socio-ecological mathematical models exist that simulate human-nature interactions. Examples include land use or resource use and their drivers and implications on different spatial and temporal scales (local to global, forward and backward looking). The seminar will provide an introduction to socio-ecological models and simulation techniques and a basic understanding of the development, structure and application of simulation models (e.g. system dynamics, agent-based models, etc.) in social ecology. The critical reflection of the strengths and weaknesses of different model approaches will be emphasized throughout the course.
Objective (expected results of study and acquired competences)
After the successful completion of the course
• The students have gained an overview of integrated social-ecological modelling approaches.
• The students have a basic understanding of which modelling methods (top-down, bottom-up) are used to analyse dynamics of society-nature interaction.
• The students have learned to critically reflect on the strengths and weaknesses of different modelling approaches.

The 5G Frontier: Millimeter Wireless
Almost limitless bandwidth beckons—if we can tame a wild region of the spectrum
In contrast with the traditional radio-spectrum management view of scarce capacity, where a finite amount of spectrum must be divided up among users, communication theorists see wireless capacity as virtually unlimited. Capacity can be increased indefinitely by going to ever smaller cells and higher frequencies that offer more bandwidth, while greater efficiency can be achieved with advanced signal processing and new spectrum-sharing policies. Among all these approaches, the greatest immediate impact would be achieved by moving to the higher frequencies in the millimeter range—the region of 30 to 300 gigahertz, where bandwidth is available and plentiful.
But in many ways, millimeter-wave wireless truly is a frontier. Today the millimeter band is largely uninhabited and inhospitable, as signals using these wavelengths run up against difficult propagation problems. Even when signals travel through free space, attenuation increases with frequency, so usable path lengths for millimeter waves are short, roughly 100 to 200 meters. Such distances could be accommodated with the smaller cell sizes envisioned in 5G, but there are numerous other impediments. Buildings and the objects in and around them, including people, block the signal. Rain and foliage further attenuate millimeter waves, and diffraction—which can bend longer wavelengths around occluding objects—is far less effective. Even surfaces that might be conveniently nicely reflective at longer wavelengths appear rougher to millimeter waves, and so diffuse the signal. [Read More]

Analyzing the Nuances of Transformers' Polynomial Simplification Abilities
04/29/2021 ∙ by Vishesh Agarwal, et al. ∙ 0
Symbolic Mathematical tasks such as integration often require multiple well-defined steps and understanding of sub-tasks to reach a solution. To understand Transformers' abilities in such tasks in a fine-grained manner, we deviate from traditional end-to-end settings, and explore a step-wise polynomial simplification task. Polynomials can be written in a simple normal form as a sum of monomials which are ordered in a lexicographic order. For a polynomial which is not necessarily in this normal form, a sequence of simplification steps is applied to reach the fully simplified (i.e., in the normal form) polynomial. We propose a synthetic Polynomial dataset generation algorithm that generates polynomials with unique proof steps. Through varying coefficient configurations, input representation, proof granularity, and extensive hyper-parameter tuning, we observe that Transformers consistently struggle with numeric multiplication. We explore two ways to mitigate this: Curriculum Learning and a Symbolic Calculator approach (where the numeric operations are offloaded to a calculator). Both approaches provide significant gains over the vanilla Transformers-based baseline.

If you’re teaching at a college or a college, it is possible to expect you free essay websites will use custom term papers to present your syllabus to your pupils. These documents serve as the backbone of free plagiarism checker for students any instructional class and form based on the grade you earn. It is crucial to not forget that your pupils can find it difficult to understand and apply what they’re learning. Consequently, if it is impossible for them to understand the info in the paper properly, they might not see the meaning behind it and not apply what they know. Because of this, they will have less odds of earning a high grade compared to other students who can grasp the information simpler.
The objective of custom term papers is mainly to assess and test a student’s academic knowledge on a specific topic. The aim of every teacher is just to impart knowledge about their students and also make them conscious of this subject matter. Every teacher has a significant role to play in making sure that his pupils gain knowledge and not simply pass out the papers. Most term papers take the kind of an essay or an analytical argument and hence require an extensive knowledge of writing and study. Enjoy with casino online games real money. Since they’re not the core content of this course, most of the educators find it very hard to present the papers without plagiarizing someone else’s work. This ends in a bad academic standing for the teacher.
As a result, prior to selecting the custom papers for your students, it is important to ensure that the paper you provide is original and never plagiarized. The purpose of doing this is to prevent the impression your students may get that you’re an unethical instructor who isn’t ready to instruct them of the right stuff. Also, you must ensure your students can easily comprehend and use what you’ve written and not have to fret about your plagiarism being discovered.
Besides these advantages, custom newspapers also help the instructor to write a more informative document which he can then use to describe his purpose clearly to his students in a better method. The pupils, so, get to find out a lot more than he ever believed possible about the subject that he was discussing from the paper. The main benefit of writing custom papers is they help you stay away from the tedious job of drafting a newspaper from scratch. That requires up to a while making it tough to present the identical data in a more healthy way. In this manner, you can concentrate your time on preparing this essay, writing the content and presenting the exact same in a much better and clearer way.
Custom papers are more time consuming, but it doesn’t necessarily mean that they lack the potency. They do work very well and hence create better grade. Compared to the typical boring and time consuming paper that you get from the school library. Even though the writing is a bit more difficult, the outcome would be well worth the effort you have put in writing the newspaper as you acquire additional knowledge and understanding in the material presented inside.
Custom made newspapers are also a great tool to enhance the communication between the instructor and his pupils. They provide the pupils the chance to comprehend the subject matter clearly, which lets them create a deeper understanding of the topic and thus increase their ability to apply what is taught at the newspaper. If you would like to keep your work as a teacher intact, you will need to ensure that you supply quality academic papers and custom newspapers are a part of your normal curriculum. Thus, before you begin preparing custom documents for your pupils, ensure that you take enough time to prepare your materials for the purpose.

Coefficient of efficiency
The ideal number of pupil-years required for a cohort to complete a level or cycle of education (e.g. the primary level) should there be no repetition nor drop-out, divided by the total number of pupil-years actually spent by the same cohort.
UNESCO. 2001. Latin America and the Caribbean (Spanish and Portuguese-Speaking Countries): Statistics and Indicators on Education, 1998/99; Regional Report. Paris: UNESCO.
example of use
The third variable, the coefficient of efficiency, is obtained by dividing the number of pupil-years normally required to complete the primary cycle by the number of pupil-years actually spent. Thus, higher coefficients indicate greater efficiency, pupils spending on average less time to complete the primary education cycle. Although these data do not show the disparities between urban and rural areas, there appears to be a weak inverse correlation between the efficiency factors and the rurality of a country. In any case, the data do illustrate how pervasive the problem of primary schooling ‘wastage’ is, rural pupils typically spending far too much time in primary education (IIEP and FAO, 2003: 88).

How are hot air balloons able to move smoothly in the air?
Many people enjoy riding in hot air balloons. Some use them for romantic picnics and marriage proposals. Others race in competitions. Being above the earth gives a whole new perspective on the world around us. As the beginning of a hot air balloon ride, the balloon is flat because the pressure inside the balloon equals the pressure outside. When the air inside the balloon is heated, the speed of movement of those air molecules increases and the pressure goes up. After a while the balloon is completely expanded and the flight is ready to take off.
You are watching: If the air inside a balloon exerts
When a person stands on the floor, his feet exert pressure on the surface. That pressure is related to both the mass of the person and the surface area of his feet. If the person were holding a heavy object, the pressure would increase because of a greater force. Alternatively, if the person stands on his toes, the pressure also increases because of a decrease in the surface area.
Gas molecules also exert pressure. Earth’s atmosphere exerts pressure because gravity acts on the huge number of gas particles contained in the atmosphere, holding it in place. Pressure is also exerted by a small sample of gas, such as that which is contained in a balloon. Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated. If the gas particles were to suddenly stop moving, the balloon would instantly deflate. TheFigure below is an illustration of gas particles exerting pressure inside a container.
Figure 13.2
Collision of gas particles with container wall.
The pressure inside the hot air balloon is affected by temperature. As the molecules heat up, they move faster and strike the inside wall of the balloon harder. This increased motion of the gas particles increases the force on an area of the balloon, producing a rise in the pressure.

Commitment and Concerted Action in the World: Uniting Humanity to a Global Environmental Purpose
We cannot resolve the environmental problems we have caused by simply becoming aware of what we have done and attaching a diagnosis to it. What is needed now is a disposition of urgency to create a comprehensive plan on which to act with full commitment and conviction. We are now at the place where we have knowledge of specific interventions that must be initiated and how to go about them. What is missing is the global political will to carry out our mission and create a positive outcome.
Many people are still not convinced that the planet is in a state of crisis or have too much personal investment in procuring material wealth and power as a primary goal for themselves. Others are not sure how to proceed or do not have the resources to be effective players in the environmental movement and need coaching and encouragement to become fully engaged. Everyone must make a genuine commitment to go green in every aspect of his and her lives and encourage others to do likewise. We must demand that our governing bodies take up this challenge as well, and create a global effort to support environmentally responsible behavior throughout the world. Every act of environmental preservation counts and empowers the process of returning the Earth to its rightful, untainted disposition.

How to scaffold children’s learning?
When the tamariki (children) are learning something new that they haven’t done before, a kaimahi (teacher) scaffolds their learning by supporting and guiding them how to do it. As the tamariki or the tamaiti (child) learn the skill, then the help from the kaimahi lessens and lessens as they get more confident in accomplishing that skill until they can do it all on their own.
A few ways of scaffolding a child’s learning can be by using demonstrations like when a tamaiti is building a block tower, the kaimahi who is scaffolding their learning can build their own tower next to them to show them a way that the blocks work the best and then it is up to that tamaiti to copy your idea by doing their tower again.
You as the kaimahi can also make suggestions if the tamaiti is having a hard time completing their activity. You can do this by, “Your block tower keeps falling down, one way to fix that would be by putting bigger blocks at the bottom and smaller ones at the top s. What other ways can we help the tower stay up?”
Another way to scaffold their learning could be to give them some encouragement. When you give them encouragement, it increases their confidence and makes them want to continue what they’re doing until its completed.
Scaffolding is very helpful for our tamariki, especially when they are needing that bot more encouragement or support from their kaimahi. It helps them gain more confidence and helps them find ways of coming to their own conclusion of how to come to the correct answer for their activity and how to accomplish it.

Thank you for your feedback
New Zealand literature, the body of literatures, both oral and written, produced in New Zealand.
Maori narrative: the oral tradition
Oratory on the marae (tribal meeting place), involving voice, facial expression, and gesture, was, and continues to be, an important part of Maori culture; it is difficult to make a clear distinction, such as exists in written literatures, between text and performance. Nor was authorship always attributable. And the Maori sense of time was such that legend did not take the hearer back into the past but rather brought the past forward into the present, making the events described contemporary.
Throughout the latter half of the 19th century, the Maori people, disastrously affected by European “minor” diseases to which they had only weak resistance, appeared to be in decline, and European scholars recorded as much Maori legend as they could, believing that the Maori would die out and that their oral culture, highly figurative and often of rare poetic beauty, deserved preservation. Some of this material was published; a great deal more was stored in libraries and is studied today, not least by Maori students and scholars intent on recovering their own cultural past.
Although Maori individuals and groups have become notable performers of various kinds of European music, their traditional music also survives. To the 19th-century European ear, the words of Maori poetry were impressive and beautiful, but the music was “tuneless and monotonous” and tended to be ignored. It is, however, inseparable from the words, and the scholars Mervyn McLean and Margaret Orbell were the first to publish text and music together. McLean and Orbell distinguished three kinds of waiata (songs): waiata tangi (laments—for the dead, but also for other kinds of loss or misfortune), waiata aroha (songs about the nature of love—not only sexual love but also love of place or kin), and waiata whaiaaipo (songs of courtship or praise of the beloved). In addition, there are pao (gossip songs), poi (songs accompanying a dance performed with balls attached to flax strings, swung rhythmically), oriori (songs composed for young children of chiefly or warrior descent, to help them learn their heritage), and karanga (somewhere between song and chant, performed by women welcoming or farewelling visitors on the marae). Some chants are recited rather than sung. These include karakia (forms of incantation invoking a power to protect or to assist the chanter), paatere (chants by women in rebuttal of gossip or slander, asserting the performer’s high lineage and threatening her detractors), kaioraora (expressions of hatred and abuse of an enemy, promising terrible revenge), and the haka (a chant accompanied by rhythmic movements, stamping, and fierce gestures, the most famous of these being war dances that incorporate stylized violence). In every aspect of this tradition, the texts, which in pre-European times survived through memorization, were inseparable from gestures and sometimes music. The most widely used modern development of these traditional forms is the waiata-a-ringa (action song), which fits graceful movements to popular European melodies.

What is developmental trauma disorder?
Bessel van der Kolk, MD,1 and colleagues are pioneers in developing DTD philosophy and diagnostic criteria, and they have shared their knowledge globally with the intent to improve the identification, treatment, and prognosis for children who have suffered traumatic experience. Van der Kolk describes DTD as a distinct condition affecting children, adolescents, and adults who have been repeatedly subjected to various forms of childhood maltreatment, including neglect and/or physical, emotional, and sexual abuse, during specific periods of their neurophysiological development.1 Child maltreatment is particularly traumatizing if it was committed by a significant caretaker, such as a parent.
Continue Reading
Other causes of DTD include witnessing acts of violence, permanent loss of an essential caregiver, institutionalization, and experiencing inconsistent custodians, such as multiple and abusive foster parents.1 Among other numerous examples, exposure to poverty, serious illness, multiple surgeries, warfare, or a life-threatening natural disaster or motor vehicle accident can traumatize a child’s psyche.1
Van der Kolk has proposed that DTD is manifested in various ways that negatively affects a victim’s capacity to relate to oneself and others.1 The following sections address some of the adverse consequences of DTD, including impaired cognitive, emotional, and social functioning, and common somatic symptoms.
Cognitive, emotional, social, and somatic effects
Children are critically dependent on the quality of their relationship with caregivers for normal development, and when they are repetitively traumatized, their psyche becomes damaged.1 They naturally internalize a caregiver’s facial expressions, emotions, and actions that serve as a “mirror” reflecting to a child his or her personal worth and identity. If caretakers are deficient or inconsistent in areas of sensitivity and emotion, or if they are violent or negligent, children endure tremendous stress. This stress is often exhibited in victims as persistent psychological states of hyper-arousal, nervousness, and agitation, and/or hypo-arousal or feeling emotionally numb.1,4
Dissociation or tainted consciousness is a characteristic defense mechanism and survival skill that DTD victims use to escape overwhelming emotion and the impact of abuse.1,4 Dissociation includes “thought suppression, minimization, and outright denial.”5 Depersonalization or feeling disengaged from oneself and the world are other described symptoms of dissociation.4,5 As a result, children learn to ignore their authentic emotions, while missing important opportunities to develop the capacity for introspection and self-managing abilities.1,6 They also learn not to trust their thoughts and feelings, causing self-perception and discernment of others to be confusing or distorted.1,6
Due to a lack of self-protection and unable to escape their plight, traumatized children develop other defenses, or maladaptive personalities, described as fight, flight, freeze, and fawn types (4-Fs).6 Fight responders possess a considerable need to control their environment, are typically disruptive or argumentative, and may display violent or aggressive behavior toward others, such as bullying.1,6 Flight personalities will flee or avoid their chaotic life, as seen in children who run away from home, become overactive, develop a compulsive or obsessive nature, or strive for perfectionism.1,6 Freeze types isolate themselves, engaging in dissociative activities such as excessive sleeping or constant use of the television or computer.1,6 Fawn responders are considered submissively co-dependent, sacrificing self-identity and healthy personal boundaries to sustain relationships or avoid rejection.6 Behaviors resulting from the 4-Fs often unjustifiably cause a child to be characterized as difficult, disobedient, rebellious, withdrawn, lazy, shy, or hyperactive.1,6 Within a traumatized and defenseless environment, the 4-Fs may be used interchangeably and serve as a child’s primary coping skills, while causing intellectual, social, sensory, and/or motor developmental delay or arrest.1,6
In an attempt to avoid abuse, children become hypervigilant of their surroundings, which further creates anxiety and tension.1,6 When caregivers are unable to provide a predictable and safe environment for their children, or offer relief to their stress, victims develop a limited capacity for emotional self-regulation and impulse control, their ability to experience healthy interpersonal bonds is restricted, and the process of learning from experience becomes fragmented and indistinct.1 These consequences are the primary origins of DTD.1 Other reactions to interpersonal trauma include high-risk and self-destructive behaviors, emotional instability, attention deficit, depression, and eating disorders.1 Deficient school or work performance, a proneness to accidents, and decreased sensitivity to pain are other signs of childhood trauma.1,7 Unexplained and persistent backache, abdominal or pelvic pain, headache, and insomnia are frequent somatic-related symptoms,4,6-7 and these may alert a health provider to identify a psycho-traumatic cause.
Ultimately, many perpetrators consistently induce intense emotions within their victims, including fear, humiliation, and unnecessary remorse resulting in poor self-esteem, or self-hatred. Above all, these children learn not to rely on themselves and others and lack a broader interpretation of life apart from their trauma-induced version. As a result, victims may develop a host of physical and psychological impairments affecting their health and ability to interact successfully with themselves and others.1,6,8

The Perpetual Prosperity—Special Exhibition of Ding Vessels Donated to Shanghai Museum
There are only a few days left of this special exhibition of bronze Ding at Shanghai Museum. Titled “Perpetual Prosperity”, this exhibition showcases 21 bronze Ding which have all been donated to the Shanghai Museum since its founding in 1952.
The Ding was a cooking pot in ancient China, and later became a type of ritual vessel more than three thousand years ago. It was often cast in bronze, an extremely scarce material at that time. Through its different usage, the Ding was used to represent different social classes. Very often it was regarded as being the most symbolic of supreme power in all bronzes.
The two main objects of this exhibition are “Dayu Ding (大盂鼎)” and “Dake Ding (大克鼎)”. They were originally donated to Shanghai Museum by the Pan Family. In 1959, Dayu Ding was transferred to the National Museum of China in Beijing. Both Ding contain long inscriptions on their inner walls. These two Ding, along with Maogong Ding (毛公鼎) in the National Palace Museum in Taipei, are known as “The Three Treasures of Bronzes”. They were all cast in the Western Zhou Dynasty (ca. 1046 BC–771 BC).
Dayu Ding was cast in the middle of the 11th century BC. It contains 291 characters on the inner wall, which records the historical event of the emperor conferring a title to the noble named Yu. The inscription is not only an important piece of historical record for researching the ceremonial system of the Western Zhou Dynasty, but also a great example of the large seal script (zhuanshu, 篆書) used at that time.
Dake Ding was cast at the end of the 10th century BC. Its inner wall records the praise by its owner Ke to his ancestor and the ceremony of the emperor conferring a title to Ke.
Next week, these two Ding will travel to the National Museum of China for another exhibition.

Wearing A Backpack: Five Key Things To Remember
It’s that time of year again, when school is starting back up. It does not matter if you are going pexels-photo-346833to kindergarten or college, making sure you have the right fit for a backpack is an important thing to consider! The wrong backpack can lead to shoulder pain, back pain, and poor posture.
The following list of “5 Tips for Backpack Safety” highlight the main things you need to look for when deciding on the “perfect” backpack!
1. The backpack should not be wider or longer than the torso, and should never hang more than 4 inches below the waistline. If the backpack hangs too low it adds weight to the shoulders causing the wearer to lean forward when walking.
2. Use both shoulder straps. Wearing just one strap can lead to an uneven shift of weight to one side, leading to neck and muscle strain, as well as causing pain in the lower back.
3.The shoulder straps should be padded and adjustable, so the backpack can be fitted to the body. If the straps are too loose it can cause the backpack to dangle and bounce off the back, and can lead to altered bio mechanics of the spine and shoulders. If there are hip and chest straps, use them to help transfer some of the weight to the body and not solely in the backpack.
4. It is important to make sure the weight of the backpack is not more than 10% of the person’s body weight. If there are multiple compartments, you want to make sure to use them and distribute the weight evenly.
5. Bigger isn’t always better. The bigger the backpack, the higher the opportunity to add more weight to the backpack leading to further stress on the body.
If you, your child, or someone you know is having some issues because of the wrong backpack, we would like to invite you to stop by the office for a backpack assessment and postural evaluation!

What Is Deadweight Loss?
A deadweight loss is a cost to society created by market inefficiency, which occurs when supply and demand are out of equilibrium. Mainly used in economics, deadweight loss can be applied to any deficiency caused by an inefficient allocation of resources.
Price ceilings, such as price controls and rent controls; price floors, such as minimum wage and living wage laws; and taxation can all potentially create deadweight losses. With a reduced level of trade, the allocation of resources in a society may also become inefficient.
Key Takeaways
• When supply and demand are out of equilibrium, creating a market inefficiency, a deadweight loss is created.
• Deadweight losses primarily arise from an inefficient allocation of resources, created by various interventions, such as price ceilings, price floors, monopolies, and taxes.
• These factors lead to the price of a product not being accurately reflected, meaning goods are either overvalued or undervalued.
• If the price of a product is not reflected accurately, this leads to changes in consumer and producer behavior, which usually has a negative impact on the economy.
What is Deadweight Loss?
Understanding Deadweight Loss
A deadweight loss occurs when supply and demand are not in equilibrium, which leads to market inefficiency. Market inefficiency occurs when goods within the market are either overvalued or undervalued. While certain members of society may benefit from the imbalance, others will be negatively impacted by a shift from equilibrium.
When consumers do not feel the price of a good or service is justified when compared to the perceived utility, they are less likely to purchase the item.
For example, overvalued prices may lead to higher profit margins for a company, but it negatively affects consumers of the product. For inelastic goods—meaning demand does not change for that particular good or service when the price goes up or down—the increased cost may prevent consumers from making purchases in other market sectors. In addition, some consumers may purchase a lower quantity of the item when possible.
For elastic goods—meaning sellers and buyers quickly adjust their demand for that good or service if the price changes—consumers may reduce spending in that market sector to compensate or be priced out of the market entirely.
Undervalued products may be desirable for consumers but may prevent a producer from recuperating their production costs. If the product remains undervalued for a substantial period, producers will either choose to no longer sell that product, up the price to equilibrium, or may be forced out of the market entirely.
How Deadweight Loss Is Created
Minimum wage and living wage laws can create a deadweight loss by causing employers to overpay for employees and preventing low-skilled workers from securing jobs. Price ceilings and rent controls can also create deadweight loss by discouraging production and decreasing the supply of goods, services, or housing below what consumers truly demand. Consumers experience shortages and producers earn less than they would otherwise.
Taxes also create a deadweight loss because they prevent people from engaging in purchases they would otherwise make because the final price of the product is above the equilibrium market price. If taxes on an item rise, the burden is often split between the producer and the consumer, leading to the producer receiving less profit from the item and the customer paying a higher price. This results in lower consumption of the item than previously, which reduces the overall benefits the consumer market could have received while simultaneously reducing the benefit the company may see in regard to profits.
Monopolies and oligopolies also lead to deadweight loss as they remove the aspects of a perfect market, in which fair competition accurately sets a price. Monopolies and oligopolies can control supply for a specific good or service, thereby falsely increasing its price. This would eventually lead to a lower amount of goods and services sold.
Example of Deadweight Loss
A new sandwich shop opens in your neighborhood selling a sandwich for $10. You perceive the value of this sandwich to be $12 and, therefore, are happy to pay $10 for it. Now, assume the government imposes a new sales tax on food items which raises the cost of the sandwich to $15. At $15, you feel that the sandwich is overvalued and believe that the new cost is not a fair price and, therefore, are not willing to buy the sandwich at $15.
Many consumers, but not all, feel this way about the sandwich and the sandwich shop sees a decrease in demand for its sandwich and a decline in revenues. The deadweight loss in this example is the unsold sandwiches as a result of the new $15 cost. If the decrease in demand is severe enough, the sandwich shop could go out of business, further increasing the negative economic effects of the new tax.

The Real Reason Vegemite Was Invented
Vegemite may not be popular in the United States, but it's possible you've heard of it or maybe even tasted it. If you've visited Australia or have Australian friends, then it's even more probable you're familiar with the bright yellow-labeled jars.
So what is this brown, thick spread made up of exactly? It's created from brewer's yeast, an ingredient used to make beer, along with other ingredients. It is often considered beneficial for the digestive tract, including treating diarrhea, according to an article in Healthline
Vegemite is a bitter and salty spread that is typically put on bread for breakfast, on crackers as a snack, and even on sandwiches, just like you'd lather on mayonnaise or mustard. Plus, it's also used as a filling for desserts and pastries, like turnovers and filled doughnuts. The taste doesn't cater to all palettes, though, so you'll find people either love it or hate it. There really isn't an in-between. But what inspired Vegemite to be created in the first place?
Vegemite is uniquely Australian
In 1922, an Australian food creator, Fred Walker, wanted to have a similar version of Marmite, a quintessential British spread with a sweet and salty taste that is made from yeast extract. He worked with a chemist, Cyril Percy Callister, to help him craft the product, now known as Vegemite. Initially, the spread didn't fly off the shelves. Yet, between promoting it alongside Kraft products in 1930 and Marmite becoming unavailable during World War II, Vegemite caught on, according to the National Museum Australia.
Vegemite was provided to the Australian Army, and by the 1950s, this dark, bitter, and savory concoction became associated as an Australian food item (via National Museum Australia).
To this day, many Australians feel a strong sense of identity, pride, and connection with Vegemite with a bright yellow label and lid. You may just find them carrying a jar around on their travels, or secretly hoarding several jars in the cupboard when they're away from the continent.

Related artworks
Look at the related works of art with students and explain that abstract art does not represent recognisable places, people or things. In abstract art, artists use elements like line, texture, colour, shape and tone to create moods and effects.
• Describe the colours in each of the works – are they bright or dull?
• Which shape families are used? Are they rounded, geometric, sharp, smooth, long, thin or angular?
• How are the shapes used? Are they layered, bunched together or spread out?
• Which mood do the shapes and colours create?
Bright colours and round shapes might make the picture look lively, friendly and happy. Shapes bunched together might make the work feel busy.
• What do the works make you think about and why? For example, they might remind you of a patchwork blanket or a busy freeway.
Resources & materials
• Cartridge paper
• Coloured paper
• Scissors
• Glue
Students design and create their work of art using the following steps:
1. Choose a shape family such as rounded shapes, angular shapes or pointed shapes.
2. Cut shapes from different coloured paper and play with arrangements on the page.
If students are not comfortable with scissors, shapes can be pre-cut and students can select shapes that match their shape family.
Experiment with arrangements of colour and ways to lay out the different shapes to create different effects.
3. Glue the shapes into place, partially overlapping each one until the page is full and none of the background is showing.
4. Give the work a descriptive title.
Present & reflect
Students share their work with a partner:
• Describe the shapes and colours you have chosen.
• What is the title of your work? Why did you call it that?

Enchanting and otherworldly in their beauty, the polar regions are some of the most isolated and least understood places on Earth. Until relatively recently, few non-indigenous people had experienced their immense majesty. And yet, while remote, these extreme environments are endlessly fascinating, and eminently worthy of witnessing firsthand, especially if you are prepared to understand what you are seeing.
What draws people to the poles again and again? What significance do these regions hold for the planet? Begin to answer these questions with Fen Montaigne, a journalist who has traveled extensively in the polar regions, as you delve into the awe-inspiring story of Ernest Shackleton's struggles in Antarctica, as well as Montaigne's own experiences.
In the latitudes where most of us live, it's easy to take the sun and its relationship with the Earth for granted. For us, the sun comes up and goes down reliably every day, yet the poles experience six months each of continuous night and constant day. What causes the seemingly strange behavior of the sun at the poles? What causes seasons? Find out in this lecture presented by astronomy professor Edward Murphy.
The North and South Poles share a history that is unique and unlike any other place on Earth. Join Professor Michael Wysession as he lays the groundwork for understanding the polar regions with a discussion of their geology, dominated by ice, ocean, climate, and even nearby outer space, as well as their similarities and differences.
Virtually every living thing in polar waters, from single-celled phytoplankton to whales, has evolved in a world dominated by sea ice. Study how Arctic and Antarctic marine ecosystems work, and consider what happens to a sea ice-dependent marine ecosystem when the sea ice begins to disappear.
Zoom in for a closer look at the unique geologic characteristics of the North Pole and surrounding Arctic Circle. First, take a brief geologic tour of the Arctic regions, then examine how the ocean, atmosphere, and surface geology all interact, and how this region has changed geologically over time.
Constellations were vital to the early Inuits' survival, as they used the daily, monthly, and annual motions of the stars for timekeeping, navigation, and tracking the seasons. Explore this tradition and how it differs from Western astronomy, then investigate what causes the breathtaking aurora borealis.
Although fewer than a half-million in number, Arctic dwellers are comprised of approximately 40 different ethnic groups. Learn how the Nenets of Russia, the Inuit of North America, and other communities survive, and how industrialization and other factors are altering traditional ways of life.
Delve into the past, present, and future of three of the most notable islands in the Arctic and sub-Arctic: Iceland, one of the world's most geologically active areas; Greenland, which dwarfs all other Arctic islands in size; and the Svalbard archipelago, home to The Global Seed Vault.

New types and characteristics of urea
New urea can be divided into existing products according to the existing products can be divided into: physical modification of urea - large particles of urea; coated urea - sulfur, resin, nutrients, including mineral powder; stability of urea - containing nitrification inhibitors, containing urease Inhibitors, containing complex inhibitors; poly urea urea - poly urea, peptide urea; fertilizer urea - zinc, boron, silicon and so on.
Large-particle urea: It is a kind of urea product with large particles after secondary condensation in the presence of formaldehyde. Compared with ordinary urea, it has a smooth surface, uniform particles and is not easy to agglomerate. Its characteristics are: 1. Low dust content, high particle strength, good fluidity, can be bulk transport, not easy to crush and agglomerate, suitable for mechanized fertilization; 2. Small surface area, slower dissolution rate after application into the soil, plus The upper single grain weight is larger, and it can be sunk into deep soil under the application in the paddy fields to reduce the loss of volatilization. 3. Due to the different urine concentration requirements of the processing technology, the content of biuret in the large-granule urea products is generally low. This is good for the crop.
Coated urea: A type of fertilizer that coats the outer surface of urea with one or more layers of permeation and diffusion barriers to slow or control the rate of dissolution of nutrients from fertilizers. Its coating materials are divided into organic and inorganic materials. Inorganic coating materials include: sulfur, silicate, phosphate rock, gypsum, calcium magnesium phosphate, bentonite and so on. Organic coating materials include: Natural rubber, natural rubber, shellac, cellulose, lignin, starch, chitin, etc. Organic coated materials are characterized by a wide range of sources and are easily biodegradable. They are environmentally friendly and suitable for slow release fertilizers.
Problems with coated urea: First, the disadvantages of the coating material itself, such as the resin-coated fertilizer, require a large amount of organic solvents to increase the cost; secondly, the problem of the nutrient release of coated urea and crop absorption; The hole technology does not pass; the fourth is the environmental problem, which easily brings secondary pollution; Fifth, the cost is high and the industrialization is difficult.
Stability urea: Through a certain process in the urea granulation process by adding a certain dose of urease inhibitors, nitrification inhibitors or urease inhibitors and nitrification inhibitor combination, and the formation of new urea varieties, can slow urea hydrolysis, control NO3- The formation of nitrogen nutrients in the soil to maintain longer time and improve effectiveness. Inhibitors - the core of stable fertilizers, including nitrification inhibitors and urease inhibitors.
The characteristics of stable urea: First, the long period of fertilizer effect, up to 100-120 days, which is twice that of ordinary urea; Second, the utilization of nutrients is high, and the utilization rate of nitrogen is increased from 30%-34% to 42%-45%; It is an increase in production of fertilizer, an average increase of 8% -18%, and a 20% reduction in fertilizer yield without reduction in production. Fourth, it saves time and labor and realizes one-time fertilization of field crops to avoid top dressing. Fifth, it is environmentally friendly and effectively reduces the environment caused by fertilization. Pollution; Sixth, the unit cost is low, and the price increase is only 3.6%-4.0% of ordinary urea.
Polymeric amino acid urea: A type of urea produced on the basis of traditional urea and added with a synthesizing synergist. The poly-alkane polymer compound functions as an ion pump and can enhance the absorption of nitrogen, phosphorus, potassium and trace elements. . At present, there are two main categories: poly-urea urea and polypeptide urea.
Polyurea urea refers to urea formed by adding a biosynthetic polyglutamic acid polymer (molecular weight 800,000-1.3 million). Its characteristics: It can play the role of ion pump to increase the affinity of ionic nutrients and root system, increase nutrient absorption and operation rate, increase crop yield by 7%-30%, and effectively increase nutrient utilization rate of fertilizer (N increase 24%-32 %); can reduce fertilizer input (reduction of nitrogen input 15% -20%); product does not harm humans, livestock, plants, in line with the requirements of green agricultural production. As for polypeptide urea, there is still relatively little research on this species in China.
With trace elements urea. Unit trace element urea: contains trace elements such as zinc, copper, iron, manganese and boron. Multielement trace element urea: Boron, copper, zinc and other trace elements and urea fused together can be prepared into multi-element fertilizer urea complex fertilizer. Humic acid urea: humic acid and urea are fused together.
Features of urea containing trace elements: 1. Contain multiple nutrient elements; 2. Reduce the number of fertilization, trace fertilizers enter with top dressing; 3. The amount is limited by trace elements, the amount will cause excessive surplus of trace fertilizers; 4. Join the process Urea production systems may have certain risks.

Solar Energy
Solar energy is the framework of all form of energies. For example plants make food from sunlight and grow up. From their hard portion firewood are formed, from their leaf and other soft portion biomass is formed. Thus firewood and biomass are product of solar energy. Similarly solar heat evaporate water from river and ocean and rainfall occurs on the top of hill which makes gain of potential energy of water that is naturally converted to kinetic energy from which hydroelectricity produced.
Q1. How is the coal product of solar Energy?
Q2. Why Solar energy is regarded as renewable energy?
Ans: Solar energy is regarded as renewable energy because it supplies energy continuously by nuclear fusion process with unlimited storage capacity.
The Nuclear fusion: The process of forming heavy nucleus by fusion of two or more light nuclei is called nuclear fusion.

The monument includes a medieval field system, several tinworks, part of a
prehistoric stone hut circle settlement, a cairn and length of reave on
Challacombe Down. Immediately to the south-east of the monument lies the
deserted medieval settlement at Challacombe. The settlement forms the subject
of a separate scheduling (SM36024).
The medieval field system survives as a series of narrow rectangular fields
denoted by substantial stone and earth banks. These mostly lie parallel with
the contours, but towards the southern and north western edges, the field
boundaries lie across the contour. The fields on the steeper slopes are
defined by the most substantial boundaries known as lynchets. The fields
were built during the medieval period by the farmers at the nearby hamlet of
Challacombe. Each field was farmed separately and the individual farmers
held fields throughout the area. Traces of ridge and furrow within many of
the fields indicates that they were cultivated, although in others the large
amounts of surface stone suggests that they could only ever have been used
for grazing.
Considerable evidence of tinworking activities also survives within the
monument. Amongst the earliest is a small area of streamworking earthworks
on the lower western slopes of Challacombe Down, but most dramatic are the
substantial rock-cut openworks which in places cut through the field system.
The largest of these is known as Scudley Beam which is up to 75m wide and 15m
deep. The openworks were formed by opencast quarrying for tin ore and the
prospecting pits, leats and reservoirs found in their vicinity, represent the
evidence for prospecting which eventually led to the discovery of the tin
lodes which were exploited using the openworks. The tin ore quarried from the
openworks was crushed and processed at nearby stamping mills. Two separate
mills survive within the monument. The first stands below Scudley Beam and
survives as a series of stone-faced pits, walls and platforms. The second
tin mill at NGR SX69197913 survives as a partly stone-faced rectangular
hollow with a wheelpit at its south western end. Another structure connected
with the tin industry survives at SX69468000 and has been identified as the
wheelpit and machinery base for a water wheel which powered flat rods serving
East Birch Tor Mine some 720m to the north. The final group of tinworking
remains include three circular buddles and a wheelpit at SX68877911. This
dressing floor was constructed in around 1927 as part of the Golden Dagger
Mine and a photograph taken at this time clearly illustrates the original
Remains of prehistoric date include part of a settlement, a length of reave
and a cairn. The settlement lies in the north western corner of the monument
and survives as two agglomerated enclosures containing three stone hut
circles together with a further single enclosure containing one hut. The
reave represents a continuation of the Hameldown North Reave and ascends the
eastern side of Challacombe Down to join the Headland Warren boundary wall at
SX69058039. The cairn stands at SX69107940 and survives as a 12m diameter
flat-topped mound standing up to 0.5m high.
All modern fences and other apparatus are excluded from the scheduling,
although the ground beneath is included.

Reasons for Scheduling
great wealth and diversity of archaeological remains provide direct evidence
The well-preserved and often visible relationship between settlement sites,
later industrial remains, gives significant insights into successive changes
monument types provide important information on the diversity of social
organisation and farming practices amongst prehistoric communities. They are
particularly representative of their period and a substantial proportion of
surviving examples are considered worthy of protection.
Tin has been exploited on Dartmoor since the prehistoric period and surviving
remains are numerous, well-preserved and diverse, with the two main types of
tinwork being streamworks and mines. The three different forms of tinwork
used to mine lode tin were lode-back pits, openworks and shafts. Lode-back
pits survive as shallow shafts which were sunk onto the lode outcrop to
extract cassiterite. These pits generally occur in linear groups following
the line of the lode, with associated spoil dumps. Many tin lodes have been
worked at the surface by digging pits onto the backs or surface exposures of
the lode to remove the mineral that lay above the water table. Openworks are
also known as beams and they were formed by opencast quarrying along the
length of the lode. The term openwork refers to the field evidence for
opencast quarrying of the
lode, which produced relatively narrow and elongated gulleys.
Shaft mining is synonymous with underground extraction, with access to the
lode being through near vertical or horizontal tunnels known as shafts and
adits. Underground workings are often complex in character, with considerable
layout variations reflecting developing extraction techniques. Within the
vicinity of most mines are found the remains of prospecting activity. This
generally takes the form of small pits and gulleys. Some mines have
associated surface buildings which provided a variety of services for the
working miners. The ore quarried from all three forms of mine was taken for
processing to nearby stamping mills.
A national survey of the tin industry in England was completed in 1999. This
demonstrated the number and diversity of surviving remains and the
significance of some areas for understanding the origins and development of
the industry. Dartmoor is one such area and here a representative selection
of sites with significant surviving remains has been identified as nationally
The medieval strip field system on Challacombe Down forms part of the best
preserved example of this type of field system in Devon and Cornwall. The
clearly defined lynchets are under certain lighting conditions visually
impressive and contribute substantially to the character of this part of
Dartmoor. The substantial nature of the remains also means that
well-preserved archaeological and environmental information relating to the
character of medieval upland agriculture will survive. Later tinworking
activity has caused some limited damage to the field system, but also
contributes additional information concerning the character of the
relationship between farming and mining. The earlier prehistoric remains
provide a contrast to the much more intensive historic activity and taken
together this area represents an important insight into the developing
character of a much used upland landscape.

Understanding Streptomyces cell division to improve antibiotic production
Every cell must divide to grow and to propagate. While most bacteria simply split in half, the decision when and where to divide is more complex in multicellular bacteria like the antibiotic producing soil bacteria Streptomyces. In fact, Streptomyces have two functionally distinct modes of cell division that lead to the formation of connected compartments and individual spores, which can be dispersed into the environment. We have recently identified a key determinant of Streptomyces cell division (https://www.biorxiv.org/content/10.1101/2021.06.12.448176v1). We now wish to further expand our understanding of how Streptomyces cell division and the formation of division septa.
The aims of the proposed project are:
1) To identify and characterise the components and the structure of division septa that are required for compartmentalised growth of Streptomyces; and
2) To investigate how the formation of these septa contributes to the overall fitness of the organism and the ability to produce antibiotics.
We are looking for an enthusiastic student who is interested in bacterial cell biology and keen to develop skills in molecular microbiology, biochemistry, fluorescence microscopy and metabolomics.
The successful candidate will be based in the laboratory of Dr Susan Schlimpert in the Department for Molecular Microbiology at the John Innes Centre, a world-leading institute for plant and Streptomyces research. The student will have access to cutting-edge research facilities for bacterial genetics, live cell imaging, protein biochemistry, metabolomics platform and a vibrant graduate student community and a stimulating research environment. Through the project and the range of training opportunities available at the institute the student will obtain excellent technical and transferable skills that are highly relevant for working in academia or industry.

Serval cats resemble cheetahs and stay near water. They are also solitary animals that have the longest legs in the cat family.
It is unknown where the serval cat originated, but it is believed to have come from Africa. It was originally called the African wildcat and was distributed across southern and western Africa.
The first servals were brought to Europe from Africa in the 17th century. In 1876, a serval was born at a zoo in Berlin. The mother was a European wildcat and the father was an African wildcat that had been taken from his natural habitat in the Congo and shipped to Europe as part of a menagerie.
Serval cats are not well-known in North America, but they have been taken in by some zoos as a way of preserving their species. They also live as exotic pets in some parts of North America.
Servals are now bred by humans in domestication, but they are still not considered domestic cats because they do not tolerate living with people, except as captives.

Writing a Good Research Paper
– by Dr. Kruti Lehenbauer
I. Purpose of Research Papers
Academic writing, and research papers in particular are not designed to “torture” students but rather designed to help students identify, define, analyze, and critically present their own observations in an objective manner. The intent is to encourage students to delve deeper into the topic of their choice (within specific criteria set by the class instructor) by finding expert opinions, studies, and observations pertinent to that topic. Presenting an argument, comparing various observations in the context of the topic, and defending a point of view with the help of data and facts instead of feelings is an essential component of success in the real world. It allows the student to learn how to think critically while asking the relevant questions.
A research paper that starts with “I am going to prove that this country is failing because of corruption…” is less likely to be an objective analysis of the country. On the other hand, writing something like, “This paper attempts to identify if corruption has played a significant role in the failure of this country’s economy…” allows the reader to recognize that a sincere effort has been made to consider all available explanations for a country’s economic failures, of which corruption might be a potential frontrunner!!
II. Final Paper Contents
A good Academic Research Paper should have the following 5 components:
1. Title Page
2. Table of Contents
3. Abstract
4. Body of the Paper
a. Research Statement and Introduction
b. History/Context of the Problem/Issue
c. Consequences of the Problem/Issue
d. Solutions to the Problem/Issue
e. Conclusion
5. References
III. My 5x5x5 Rules for Body of the Paper:
1. Only 5 main headings:
a. Research Statement and Introduction
b. History/Context of the Problem
c. Consequences of the Problem
d. Solutions to the Problem
e. Conclusion
2. Section (a) and (e) should be no more than 3 to 5 sentences. Your ability to present this information succinctly matters!
3. For (b), (c), and (d), create 5 paragraphs in each section; one for each “new” information that you are bringing in. Compare and contrast the ideas found in literature regarding that information and cite your sources clearly. Use both short-term and long-term views, for sections (c) and (d).
4. Use graphs and tables wherever possible to illustrate data – a good paper has at least 5 of these visual elements – remember to use them to enhance your paper, and not just to “fill in space.”
5. At least 5 scholarly articles from published and reputed journals are required. The rule of thumb is that for each page of writing, there should be 1 formal reference article – therefore, for a 10-page paper, one would usually expect 10 scholarly articles to be used.
IV. Academic Sources:
a. Using Scholarly Articles
While it is tempting to use popular (a.k.a. easy to “Google”) sources for your writing, these do not work in an academic setting while presenting your thesis or arguments. Even though “Wall Street Journal” has the word “Journal” in it, don’t confuse it for a Scholarly source. Many people confuse popular sources for scholarly sources because they don’t always understand the difference. The following sources offer an insight into what constitutes Scholarly sources for use in writing an academic research paper:
1. University Library, University of Illinois at Urbana-Champaign. “Determine If a Source Is Scholarly”(article): https://www.library.illinois.edu/ugl/howdoi/scholarly/
2. Ryerson Library “What are Scholarly Sources?”, YouTube video (3 mins long): https://youtu.be/8fpbQxcj9sQ
3. Rutgers Libraries “Scholarly Literature Timeline: Is This Article Scholarly?”, YouTube video (5 mins long): https://youtu.be/W5lQpkob2UE
b. Using Popular Sources
Typically, one should try to avoid using popular sources in their research papers, unless it is in the context of describing a recent event that is not yet covered in the scholarly literature. Sources such as Interest groups, non-profit private organizations, academic blogs, newspapers, daily journals fall under the popular sources category. I recommend that students use no more than TWO (and ideally, ZERO) popular sources in their research papers.
Open source content, such as Investopedia, Wikipedia, Dictionary.com, etc. are almost never a good idea to use in a research paper – they fall in the Unacceptable Sources category. Trust me, if it is valid, you will be able to find a better (academic or scholarly) source to use… and if it is not valid, you should not be using that to present your argument, anyway!
V. Formatting Suggestions for Research Papers:
1. Create a Title Page as suggested in the APA formatting rules published by Purdue University (https://owl.english.purdue.edu/owl/resource/560/01/)
2. Create a separate page for the Table of Contents – if you use the “Heading” style for your paper sections, you can insert a Table of Contents by using the command on the References tab in MS Word.
3. Create a separate page for the Abstract – use Page Breaks to ensure that the abstract is on its own page. Write the final abstract AFTER you have completed the whole paper. Writing an abstract before writing a paper is like putting the cart before the horse. Remember that the abstract should cover the entire scope of your paper in no more than 4 to 5 sentences. A clear and succinct explanation of what you are writing about in the paper is of utmost importance.
4. Use a standard font such as Times New Roman or Calibri (default in Office 2010 and beyond) and set font size to 11 or 12 for the body of the paper. Use double spacing between lines, unless specifically suggested otherwise. Also, don’t use two spaces after a period.
5. 1” margins for the pages (you can use the Layout function in MS Word to set this up)
6. Use Page Break to create a separate page for References. MS Word has a “References” tab that allows you to Manage Sources and create a bibliography using APA (as well as other styles).
7. Try to set up “justified” text as opposed to Left-aligned, centered, or right-aligned text for giving a clean, crisp “look” to your paper.
8. Always perform a spelling and grammar check before submitting your paper.
9. Always make sure that the articles listed on the References page are cited in the paper, and vice versa. Follow Reference guidelines available on the APA format Purdue University page, to list the articles used: (https://owl.english.purdue.edu/owl/resource/560/05/)
10. Avoid using first person verbiage. If a point requires a more “personal” presentation, it is better to use “we” or “us” (to include the reader) rather than “I” or “me”. This automatically discourages the tendency of presenting unsubstantiated information or opinions. For instance, I might call the time 4:00 PM, afternoon… but you might prefer to call it early evening. If I were to present this in a paper, having to use “we” forces me to avoid both of these and find a more objective statement such as “We observe that around 4:00 PM…”
I hope this article helps you with your research paper writing for this class. I am always happy to respond to any questions, concerns, or clarifications you might need help with.

BA On Defensive Catching Prospects
New, 11 comments
BA listed the top 10 defensive catchers in each of the top four levels and the Astros landed three....
Troy Taormina-USA TODAY Sports
Analyzing catcher defense has been a significant focal point in saber metrics for awhile now. Pitch framing has been one of the largest focal points, however that is something that we just don't have much data for in the minors.
Baseball America attempted to do that yesterday with an article ranking the top defensive catching prospects based on what information we do have. Now, this is limited to passed balls, caught stealing, and caught stealing rate. What they did was use the caught stealing totals and passed ball totals compared to league average.
The Astros landed three on the lists for the four full-season levels.
Tyler Heineman and Rene Garcia both landed on the Double-A list. Heineman came in at number three while Garcia was tenth.
Roberto Pena landed on the High-A list as the top defensive catcher. He had an astounding caught-stealing rate of 56.5%. That was the highest among all listed catchers at all levels. Interestingly, in the notes they mentioned he didn't have the same raw arm strength as others.

Note on the Randic Energy of Graphs
Jun He, Yan-Min Liu, Jun-Kang Tian
If $G$ is a graph on $n$ vertices, and $d_i$ is the degree of its $i$-th vertex, then the Randic matrix of $G$ is the square matrix of order $n$ whose $(i, j)$-entry is equal to $1/\sqrt{d_id_j}$ if the $i$-th and $j$-th vertex of $G$ are adjacent, and zero otherwise. In this note, we obtain some new lower and upper bounds for the Randic energy.

Question: Is it hard to date someone with schizophrenia?
Can you live with someone with schizophrenia?
Do schizophrenics cry?
If theyre frightened by the perception, they might try to hide their fear, or cry out or run away. Some people have persistent visual hallucinations, such as small children or animals that frequently appear or follow them around.
What do schizophrenics fear?
Schizophrenia affects a persons perception and can involve hallucinations and delusions. When these happen, it can be hard to know what is real and what is not. Paranoid delusions can cause a person to fear that others are watching them or trying to harm them.

Organizations that facilitate structured and competitive markets for purchasing health coverage. The Health Insurance Marketplace, or "Exchange," offers standardized health insurance plans to individuals, families and small businesses. Certain states operate their own marketplace, while others opt for a partnership exchange where the federal government manages the marketplace. In each state, various private insurance companies submit plans to be included in the marketplace. The marketplace plans are separated into four primary levels: Bronze, Silver, Gold and Platinum, each based on the average percentage the plan pays toward health-care services.

Production and technology choice under emissions regulation: Centralized vs decentralized supply chains
Publication in refereed journal
摘要To study how emissions regulations impact supply chain operations, we consider a supply chain where a supplier produces and sells raw material to a manufacturer, who then uses it to produce a final product to satisfy random market demand. Both firms are equipped with two production technologies, one of which is costlier, but generates fewer emissions than the other. Each firm’s emissions are capped by the amount of allowances it holds, and if the firm over-emits, it pays a penalty. We solve the optimal solutions of a centralized system, both jointly regulated and separately regulated, and a decentralized system. We find that the relationships between the emissions abatement cost, the emissions penalty, and the salvage value of the allowance largely determine the technology choice of the firms. For the centralized system, joint regulation results in a higher profit than separate regulation, but it may not result in a larger production quantity. For the decentralized system, under a more stringent regulation (fewer allowances), the firms may produce more while not using more of the green technology; and if the manufacturer has fewer allowances, the manufacturer and the whole chain may be better-off. The numerical study further illustrates that adding a green technology is always economically beneficial to the centralized supply chain, although it may hurt the manufacturer and the decentralized chain. In the scenarios where only either the supplier or the manufacturer is regulated, we show analytically that the centralized system produces more, uses more green technology, and generates more emissions than the decentralized one. More interestingly, the decentralized supply chain with the regulated supplier produces more, has a higher profit, and emits more than the supply chain with the regulated manufacturer when the emissions intensities of the production technologies are the same for the firms.

Send from email partner
After the email client application and Interchange have been configured properly, use the following guidelines for sending email messages with attachments from the email client to Interchange.
1. Each email message can have one or more attachments. Upon receiving the email, Interchange treats each attachment as a separate document. In the case of multiple attachments, Interchange identifies each document as being split from an original message.
2. Use the Interchange partner’s email address as the “to” address.
3. If the Interchange partner is the true receiver of the message, leave the subject line of the message blank. In other words, leave the subject line blank when the Interchange partner does not re-route the message to a third party.
4. If the Interchange partner plans to re-route the message to a third party, add to the message subject line the routing ID of the ultimate receiver (the party to whom the Interchange partner forwards the message) and the routing ID of the sending party (the email client). The subject line format must be:
5. truereceiverID;truesenderID
6. If the routing IDs contain spaces or non-alphanumeric characters, enclose the IDs in quotes like so:
7. "true receiver ID";"true sender ID"
8. Although supported, non-alphanumeric characters in routing IDs is not a best practice.
9. If the email sender does not know what routing ID to use, ask the Interchange partner who performs the re-routing.
10. In a re-routing the scenario, the Interchange partner who performs the re-routing is called the hub. The hub partner must enable re-routing. To do so, click Trading partners on the navigation graphic at the top of the community summary page. Select Allow messages to be re-routed and click Save changes.

Smart reliability and cost are defined by
Smart Materials Classification Smart Materials- Introduction Classification of Smart Materials Different Types of Smart Materials Their Applications Conclusion References Materials are essential and primary thing to the construction of any engineering structure, from the smallest integrated circuit to the largest bridge. In a new day every technology, the performance, reliability and cost are defined by the which materials is being used.
As a conclusion, the drive to develop new materials and processes to improve existing properties of materials science and engineering is one of the most important and dynamic engineering disciplines. Materials science and engineering have strong relationships among the structures, properties, processing and performance of materials are very resulted to their function in engineering structures. Materials design engineers design materials for particular applications and develop improved processing techniques and structures. Materials encompasses in different types of areas, it is often divided according to types of materials like metals, ceramics, polymers, and semiconductors. Material has to many applications such as biomaterials, electronic materials, magnetic materials, structural materials. Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled by external boost such as stress, temperature, moisture, pH, electric or magnetic fields. Smart materials have been around for many years and they have found a large number of applications. The use of the terms ‘smart’ and ‘intelligent’ to describe materials and systems came from the United States and started in the 1980’s despite the fact that some of these so-called smart materials had been around for decades.

Many of the smart materials were developed by government agencies working on military and aerospace projects but in recent years their use has transferred into the mechanical and civil engineering sector for applications in the automotive, construction, transport, medical, leisure and domestic areas. Smart material system which has intrinsic sensor, actuator and control mechanisms whereby it is capable of sensing a stimulus, responding it and reverting to its original state after the stimulus is removed. Smart materials are also called as functional materials. A material can be considered smart when an input stimulus of a variable changes the output of other variables not given as input. There are many groups of smart materials each exhibiting particular properties which can be used in a variety of high-tech and everyday applications. These include shape memory alloys, piezoelectric materials, magneto-rheological and electro-rheological materials, magneto strictive materials and halochromic materials, pH sensitive polymer, smart inorganic materials, temperature responsive polymers, ferrofluid, photomechanical materials, polycaprolactone, self-healing materials, die-electric elastomers, which change their color in reaction to various stimuli. The distinction between a smart material and a smart structure should be emphasized.
A smart structure incorporates some form of actuator and sensor which can be made from smart materials. It controls hardware and software to form a system which reacts to its environment. Like a structure of an aircraft wing which continuously alters its profile during flight to give the optimum shape for the operating conditions at the time.
Shape Memory Alloys What is shape memory alloys? Shape memory alloys are one of the most well-known types of smart material. The shape memory effect was seen in the gold-cadmium alloy in 1951. After ten years, in 1962 an equitoxic alloy of titanium and nickel was found to exhibit a significant shape memory effect and it is named as “Nitinol”, because it is made from nickel and titanium.
Working of shape memory alloys Shape memory alloys display two distinct crystal structures. Temperature and internal stresses which play a role in part of super-elasticity. It determines the phase that the Shape memory alloys will be at Martensite exists at lower temperatures, and austenite exists at higher temperatures. When a Shape memory alloys is in martensite form at lower temperatures, the metal can easily be deformed into any random shape. When the alloy is heated, it goes through transformation from martensite to austenite state. In the austenite phase, the memory metal “remembers” the shape it had before it was deformed. From the stress versus temperature graph as given below, we can see that at low stress and low temperature, martensite exists. At higher temperature and higher stress, austenite exists.
Shape memory alloys undergo temperature-dependent phase changes so it also changes its structure as given graph below:- Uses of Shape Memory Alloys in Aerospace Engineering Shape memory alloys have a large number of uses in aerospace, medicine and the leisure industry which is described as given below: It is uses in variable geometry chevron (VGC) and variable area fan nozzles (VAFN). It is uses as different type of actuators as given below: -Telescopic wing system -Servo valve -Retractable landing gear -Reconfigurable Rotor Blade (RRB) Uses of Shape Memory Alloys in Medical Engineering Material nitinol is biocompatible, it can be used in the body without an adverse reaction, so it has found a number of medical uses. These include stents in which rings of SMA wire hold open a polymer tube to open up a blocked vein, blood filters, and bone plates which contract upon transformation to pull the two ends of the broken bone in to closer contact and encourage more rapid healing. It is also possible to use in dentist field for orthodontic braces which straighten teeth. It can be made in desired shape of the teeth. Uses of Shape Memory Alloys in Domestic applications Shape memory alloys can be used to replace bimetallic strips in many domestic applications. It offers the advantage of giving a larger deflection and exerting a stronger force for a given change in temperature.
They can be used in cut out switches for kettles and other devices, security door locks, fire protection devices such as smoke alarms and cooking safety indicators. Uses of Shape Memory Alloys in Manufacturing applications It can be used as couplings for connecting two tubes. Diameter of couplings is made slightly smaller than the tubes. The coupling is deformed such that it slips over the tube ends. The temperature changed to activate the memory. The coupling tube shrinks to hold the two ends together but can never fully transform so it exerts a constant force on the joined tubes.
Piezoelectric Materials The piezoelectric effect was discovered in 1880 by Jaques and Pierre Curie who conducted a number of experiments using quartz crystals. It makes piezoelectric materials the oldest type of smart material. These materials, which are mainly ceramics, have since found a number of uses. What is the piezoelectric effect? The piezoelectric effect and electrostriction are opposite phenomena and both relate a shape change with voltage. As with shape memory alloys the shape change is associated with a change in the crystal structure of the material and piezoelectric materials also exhibit two crystalline forms.
One form is ordered and this relates to the polarization of the molecules. The second state is non- polarized and this is disordered. If a voltage is applied to the non-polarized material a shape change occurs as the molecules reorganize to align in the electrical field. This is known as electrostriction.
Conversely, an electrical field is generated if a mechanical force is applied to the material to change its shape. This is the piezoelectric effect. The main advantage of these materials is the almost instantaneous change in the shape of the material or the generation of an electrical field.
What materials exhibit this effect? The piezoelectric effect was first observed in quartz and various other crystals such as tourmaline. Barium titanite and cadmium sulphate have also been shown to demonstrate the effect but by far the most commonly used piezoelectric ceramic today is lead zirconium titanite (PZT). The physical properties of PZT can be controlled by changing the chemistry of the material and how it is processed.
There are limitations associated with PZT; like all ceramics it is brittle giving rise to mechanical durability issues and there are also problems associated with joining it with other components in a system. Uses of piezoelectric materials The main use of piezoelectric ceramics is in actuators. An actuator can be described as a component or material which converts energy (in this case electrical) in to mechanical form. When an electric field is applied to the piezoelectric material it changes its shape very rapidly and very precisely in accordance with the magnitude of the field. Applications exploiting the electro strictive effect of piezoelectric materials include actuators in the semiconductor industry in the systems used for handling silicon wafers, in the microbiology field in microscopic cell handling systems, in fiber optics and acoustics, in ink-jet printers where fine movement control is necessary for vibration damping.
The piezoelectric effect can also be used in sensors which generate an electrical field in response to a mechanical force. This is useful in damping systems and earthquake detection systems in buildings. Most well-known application is in the sensors which deploy car airbags.
The material changes in shape with the impact thus generating a field which deploys the airbag. Magneto and electro-rheological materials There are some smart fluids which change their rheological properties in accordance with their environment. What are smart fluids? There are two types of smart fluids which were both discovered in the 1940s. Electro-rheological (ER) materials change their properties with the application of an electrical field and consist of an insulating oil such as mineral oil containing a dispersion of solid particles. Magneto- rheological materials (MR) are again based on a mineral or silicone oil carrier but this time the solid dispersed within the fluid is a magnetically soft material such as iron and the properties of the fluid are altered by applying a magnetic field. In both cases the dispersed particles are of the order of microns in size.
Working of smart fluids In both cases the smart fluid changes from a fluid to a solid with the application of the relevant field. The effect takes milliseconds to occur and is completely reversible by the removal of the field. The small particles in the fluid align and are attracted to each other resulting in a dramatic change in viscosity as shown in below given figure.
Schematic diagram showing the structure of an electrorheological fluid between two electrodes. Uses of smart fluids Uses of these unusual materials in civil engineering, robotics and manufacturing is explored. Automotive and aerospace industries where the fluids are used in vibration damping and variable torque transmission.
MR dampers are used to control the suspension in cars. Dampers are also used in prosthetic limbs to allow the patient to adapt to various movements. Chromatic materials Chromatic materials refer to those which change their color in response to a change in their environment, leading to the suffix chromic.
A variety of chromic materials exist and they are described in terms of the stimuli which initiate a change as given below: Thermochromic materials change with temperature. Photochromic materials change with the light level. Piezo chromic materials change with applied pressure. In the case of electrochromic, solvate chromic and Carso chromic materials the stimulus is either an electrical potential, a liquid or an electron beam respectively. Thermochromic, photochromic and piezo chromic materials are the most popular with the first two groups finding everyday applications. Working of thermochromic materials There are two types of thermochromic systems as given below: Based on liquid crystals rearrangement Bases on molecular rearrangement In either case at a given temperature a change in the structure of the material occurs giving rise to an apparent change in color. The change is reversible so as the material cools down it changes color back to its original state. In liquid crystals the change from colored to transparent takes place over a small temperature range around 1 C and arises as the crystals in the material change their orientation as shown in figure.
Above figure shows liquid crystal contains needle shaped particles which are arranged randomly below the transformation temperature at top. Above this temperature the particles are aligned, changing how the material reflects light, thus showing a change in color bottom. However, liquid crystals are relatively very expensive and so where there is no need for the color change to take place in a very narrow temperature window molecular rearrangement material are employed. Leucocytes change color by molecular rearrangement and the color and active temperature range of the dye can be controlled by changing the chemical groups on the corners and central site of the molecule. Leucocytes have a broader temperature range than liquid crystals and will usually become colorless over approximately 5 C. In both cases the thermochromic material is encapsulated inside microscopic spherical particles to protect it.
These encapsulating molecules must themselves be transparent and able to withstand the thermal cycling which the thermochromic artefact will undergo. Uses of thermochromic materials Since thermochromic pigments can be used in a variety of ways they have found a varied range of applications. The pigments can be incorporated in to dyes for fabric to produce clothing which changes color with temperature. Thermochromic inks can also be used for printing on to clothing and food packaging. Thermochromic toothbrushes have been produced that change color as they are warmed in the hand. It takes roughly two minutes to warm the brush enough to see a change in the color and this is the length of time dentists recommend teeth should be brushed. Thermochromic thermometers have been developed as they offer significant safety advantages over traditional glass or mercury thermometers. The plastic substrate consists of stripes of different colors representing the different temperatures.
This is then coated with a layer of thermochromic dye of varying thickness. It is thinner at the cool end of the thermometer. It is higher at temperature end. As the thermometer is warmed by placing it on the forehead the thin layer of dye warms up and becomes transparent first. The higher the temperature the thicker the layer of dye which can be warmed sufficiently to change color. This principle is also employed in the tester strips which appear on the sides of some batteries, but this time the heat is generated by the resistance heating effect of a small electrical current flowing across the battery. Thermochromic materials have also found safety applications in kettles and baby spoons. The body of the kettle is actually made from pink plastic.
However, this contains a small amount of a thermochromic dye which is blue at room temperature and becomes transparent when warm, thus showing the pink color. A series of photographs showing the change in color as the kettle is boiled are shown in figure as given below: Figure shows gradual change in color as the thermochromic kettle boils. Thermochromic pigments have also been employed in baby spoons which change color to warn if the food is too hot for feeding. Babies generally like to eat their food no hotter than one degree above body temperature, so the spoons are designed to change color at 38 C. The room temperature and hot states of such a spoon are shown in figure as given below: Figure shows that thermochromic baby spoon at room temperature (top) and after immersion in boiling water (bottom). The food more rapidly and spoon changes from red to yellow.
The bright yellow color has been achieved by immersing the spoon in boiling water. Thermochromic dyes with a higher temperature resistance and higher transition temperature have also been produced and incorporated in to pans. These pans have a small colored circle in the bottom which changes color when the pan has reached the optimum temperature for cooking. Polymers A polymer is a large molecule or macromolecule, composed by many repetition subunits. Because of that range of properties, both synthetic and natural polymers play a very essential and ubiquitous role in everyday life. Polymers range from familiar synthetic plastic such as synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function.
Polymers should be in both natural and synthetic form. That are created via polymerization of many small molecules which is known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, visco-elasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.
Polymers has two types: Natural polymeric material such as shellac, amber, wool, silk and natural rubber. y of other Natural polymers exist such as cellulose which is the main constituent of wood and paper. Synthetic polymers includes polyethylene, polypropylene, polystyrene, polyvinyl chloride, synthetic rubber,phenol formaldehyde resin or Bakelite, neoprene, nylon, polyacrylonitrile, PVB, silicone, and many more.
Polymerization process Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. For example, in the polymerization of PET polyester.
The monomers are terephthalic acid (HOOC-C6H4-COOH) and ethylene glycol (HO-CH2- CH2-OH) but the repeating unit is -OC-C6H4-COO-CH2-CH2-O-, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. Laboratory synthetic methods are generally divided into two types as given below: Step-growth polymerization Chain-growth polymerization Polymer structure An important microstructural feature of a polymer is its architecture and shape which is related to the way branch points lead to a deviation from a simple linear chain. Branched polymer molecule is composed of a main chain with one or more substituent side chains or branches. Types of branched polymers include star polymers, comb polymers, brush polymers, dendronized polymers, ladder polymers, and dendrimers.
A polymer’s architecture affects many of its physical properties but not limited to such as solution viscosity, melt viscosity, solubility in various solvents, glass transition temperature and the size of individual polymer coils in solution. Mechanical properties of polymers: Tensile strength The tensile strength of a material quantifies how much elongating stress the material will endure before failure. Very important applications are polymer’s physical strength and durability.
Tensile strength increases with polymer chain length and cross linking of polymer chains. Young’s modulus of elasticity Young’s modulus quantifies the elasticity of the polymer. It is defined as for small strains as the ratio of rate of change of stress to strain. Like tensile strength, this is highly relevant in polymer applications involving the physical properties of polymers such as rubber bands. The modulus is strongly dependent on temperature.
Visco elasticity describes a complex time-dependent elastic response, which will exhibit hysteresis in the stress-strain curve when the load is removed. Transport properties Transport properties such as diffusivity relate to how rapidly molecules move through the polymer matrix. These are very important in many applications of polymers for films and membranes.

In what way can high school teachers better improve students’ study interests?
1. Applying more technology in class
2. Explaining the close connection between what they are learning and the world
3. Arranging students to work in group assignments
Choose one of them and explain the reasons. Use specific details and examples to support your answer.
Most high school students often find studying rather boring, most likely because the textbooks are too plain and teachers’ lecturing is not engaging. Some teachers hence employ various technology and organize group discussions to engross students in class. In fact, neither of the two methods is viable. A teacher should primarily explain to students how the knowledge in class is closely connected with the real life.
* Viable adj. 可行的
* Engaging adj. 引入入胜的
Firstly, it doesn’t take a leap of imagination topicture how chaotic a class would be during group discussions. Instead of remaining seated, some students may move around to exchange papers while others are in a heated with frequent digressions. The noises they make may “disturb” those free riders in a group - those who are glued to their phone and contribute nothing to the discussion. Teachers, sophisticated or otherwise, can hardly intervene in such a troubled environment, and if teachers fail to keep the group assignments well organized, what is the point of arranging group assignments? And if most students are doing irrelevant things, how can their study
* Digression n. 离题
* Sophisticated adj. 干练的
* Intervene v. 干预
* Be glued to 黏在；盯着
Secondly, due to the distractions, the application of modern technology, like some electronic gadgets, is no better than the arrangement of group assignments. To clarify, the use of multi-media tools in class, which seems to be fresh at first glance, may intrigue students, but over time, owing to the aesthetic fatigue, students minds might wander off as teachers switch among blackboards, screens and textbooks. Not to mention, what students really interested in may not be the knowledge integrated in the slides or videos, but the gadgets used instead.
写作时除了句间的衔接，段落与段落间的衔接也有，三选一驳回的两段间的衔接不妨就在中心句写明两个选项的对比，即A 不比B 好到哪里去。
* Fatigue n. 疲劳；v.使疲劳
* Wander off 漫游；闲逛
It thus follows that showing the real-world connection to the lesson is the most desirable way to interest students. As high school students always hope to glimpse the world outside the ivory tower, teachers should take advantage of such hope and try to relate their subject to how it can be applied in a workplace or everyday life. After knowing what they are learning mirrors real-life context, students can be more motivated to learn new concepts and skills. My personal experience as a writing teacher is a telling example of this point. My students always nod off when I am using some big words like logical or critical thinking, and they wouldn’t be energized simply because I play a video or ask them to discuss with each other. Contrarily, they are more intrigued when I tell them that a well-articulated resume can talk their way into a promising job or an Instagram post with many punchlines can increase their followers.
* Nod off 打瞌睡
* Well-articulated 说的清楚的
* Promising 有前景的
* 通过xxx方式完成某事
verb+one’s way+preposition+something
With the aforementioned points made, the first and the third options can be quick dropped, and the second option, which better caters to student’s genuine needs, is obviously more productive in improving students’ study interests.
* genuine need 切实的需求
* drop v. 略过，不予考虑

What is intrinsic value and how do you calculate the intrinsic value of stocks?
Assessing the intrinsic value of an asset is a common way of finding out whether shares are over- or undervalued. Find out what intrinsic value is and how to calculate it.
Charts (1)
What is intrinsic value?
Intrinsic value is the measurement of how much an asset is worth, given the current financial performance and level of risk. It is a way of assessing the true value of an investment, without other market factors playing a role in the analysis.
There are different ways to arrive at a valuation for an asset, but the intrinsic value is based on objective calculations of both qualitative and quantitive factors, rather than just its current market value. These factors include:
• Business model
• Governance
• Target markets
• Financial ratios
• Financial statements
Most commonly the term intrinsic value is used to describe the price of a company’s stock. Not all assets have cash flows, which make it difficult to calculate the intrinsic value. For example, commodities or cryptocurrencies themselves do not generate a stream of income, only by market speculation.
What is the intrinsic value of a stock?
The intrinsic value of a stock, or a business, is the combined value of all its expected future cash flows – with the discount rate applied. The intrinsic value only considers the business’ factors (earnings and dividends) rather than any speculation and comparisons to other stocks in the sector.
Financial analysts will build models to assess the intrinsic value of a stock, outside of its perceived market value. The traders who use these models as part of their strategy are known as ‘value investors’ or ‘value traders’.
The theory goes that any differences between the true value of a stock and its current market price can be exploited for profit.

How to calculate the intrinsic value of a stock
There are a few different ways to calculate the intrinsic value of a stock, the most popular models are:
1. Dividend discount-based
2. Residual income-based
3. Discounted cash flow-based
1. Discounted cash flow model
Discounted cash flow (DCF) analysis is the most common valuation, which simply assesses the cash flows over several future periods. It attempts to assign an intrinsic value based on the projections of how much money a company will make going forwards.
The value of expected future cash flows is calculated using a discount rate – an interest rate that helps determine if cash flows will be worth more or less than in the present.
The discounted cash flow formula requires three values:
1. The estimated future cash flow (CF)
2. The discount rate (r)
3. A method for valuing the company at the end of the cash flow estimate, known as terminal value (TV)
The formula works as follows:
DCF = CF1/(1+r)1 + CF2/(1+r)2 + … + TV/(1+r)n
You’d add a cash flow for any subsequent periods under examination. For example, if you wanted to look two years ahead, five years, ten years, and so on.
If the DCF is above the current cost of the investment, the opportunity could result in positive returns.
2. Residual income model
The residual income model looks at the difference between the earnings per share and per-share book value to calculate the intrinsic value of a stock. It is the income a company generates after accounting for its cost of capital equity. So, it uses shareholders’ earnings opportunities to create a valuation.
The calculation for residual income is net income – equity charge (equity capital multiplied by the cost of equity). The residual income valuation method takes this figure and uses it as follows:
Stock value = the current book value of a company + the sum of the residual income of a company divided by the cost of equity + 1.
The model looks at the company’s economic profitability, but it is a forward-looking estimate so not entirely reliable.
3. Dividend discount model
A lot of models will consider a company’s cash flow. The dividend discount model (DDM) accounts for the company’s ability to pay dividends out to shareholders, reflecting its perceived future cash flow. There are a few different versions of this model, the most basic of which is:
Stock value = expected dividend per share / (cost of capital equity - dividend growth rate)
How does intrinsic value change over time?
The intrinsic value of a company will change over time as its financial performance alters. If a company experiences significant periods of growth that improve its cash flow projections, its intrinsic value will rise. Likewise, if the company experiences a period of downturn and incurs large losses, its intrinsic value will fall.
It’s important to note that changes in the intrinsic value of a company might not be reflected in its share price. For example, some companies – like start-ups – often make huge losses for years, but their share prices rocket on the back of speculation.
Why do shares trade above their true value?
Shares that trade above their true value are ‘overvalued’. This happens when the market price is driven by illogical or emotional decision making that doesn’t reflect the intrinsic value.
Although investors and traders don’t want to pay above the odds for shares, they can get swept along amongst market hype surrounding a stock. This is what happens in speculative bubbles.
Eventually, an overvalued stock will decline in price. This is known as a stock market correction.

What happens when a stock trades below its intrinsic value?
A stock trading below its intrinsic value is known as an undervalued stock. An undervalued stock isn’t in financial hardship, but its share price does not reflect its current earnings.
Once investors realise a stock is undervalued, they’ll enter the market and the share price will rally. Identifying stocks below their true value and taking advantage of the upswing can be a great strategy for earning profits. But it can be difficult to identify when a share price will rally.

Fahrenheit 451: The Rise And Fall Of The Nazi Regime
708 Words3 Pages
Pre-1953 saw the rise and fall of the Nazi regime over most of Europe, during the 1930’s an associated symbol with the regime included book burnings carried out by Nazi Germany. These burnings played a major role in repression as there was heavy censorship of information throughout this era. War is reflected throughout Fahrenheit representing the repression and censorship experienced by society creating an atmosphere of fear. The Cold War that followed in later years against the Soviet Union and the West world idealised communism over democracy. Creative and artistic freedom was cracked down upon as writers and film makers where required to regulate content although Americans at the time where guaranteed freedom of speech and freedom of press. A heavy pressure to conform within society, following the wars again sparked fear worldwide; reflected in the novel Montag strives to keep up with society’s dismissal of books, if he speaks out…show more content…
Similar to today, the attempt to censor formats of media arises from organised pressure groups, these usually determine what is accessible to children; whether through films/television or today’s internet.

The Influence Of The Renaissance And Reformation
1625 Words7 Pages
One of the main points of debate during the Renaissance and Reformation was the issue of who held the ultimate authority in the church. The intellectual leaders, called Humanists, of the Renaissance, the reformers of the Reformation, and the Roman Catholic Church each had their view, and each believed they stood on the word of God in defense of said view of that authority. Much debate occurred, friendships were lost, lives were lost, popes asserted their power, kings pushed back, the world was changing, Protestantism was growing, and people were looking for a personal relationship with Jesus Christ. The Humanists of the Renaissance did not challenge the truth of Christianity, but instead focused on man’s ability to achieve excellence through his own effort, like the Greek word arete, meaning human excellence. In northern Europe, humanism was very religious and remained deeply attached to the Holy Bible and the church.1 The Renaissance brought about a spiritual revival to northern Europe. The Italian humanists already knew Greek and Latin, while the northern humanists wanted to learn these languages to further their study of the bible in its original text. As the humanists’ appetite for knowledge and growth in Christianity continued to expand, their criticism of the Roman Catholic Church increased. This prompted the leaders of the Roman Catholic Church to flex their religious might to establish their authority over spiritual matters. This will be discussed later. John

Hormones and Steroids
Hormones are chemical messengers that have diverse chemical structures including eicosanoids, steroids, amino acid derivatives, peptides, and proteins that are secreted into the blood, which carries them to organs and tissues of the body to exert their functions. They are essential for every activity of life, including the processes of such as digestion, metabolism, respiration, tissue function, sensory perception, sleep, excretion, lactation, stress, growth and development, movement, reproduction, and mood. Many hormones, such as neurotransmitters, are active in more than one physical process.
Hormones are the chemical signaling molecules that are secreted by the glandular system directly into the circulatory system which are carried further to the target organs. Steroids are four ringed organic compounds which are diverse chemical structures of hormones. Hormones and steroids act in a very organized way in our everyday life. They enhance the body working mechanism. The over dose or less production of any one of them may result in various side effects leading to hormonal imbalance. They play a vital role in everyday activity of our life such as sleep, metabolism, digestion, growth, reproduction, excretion, lactation, movement, mood swings etcetera.

The founding event of the Republican Party is a matter of some dispute. Some point to a mass meeting in Ripon, Wisconsin in March 1854; others cite a later gathering in Jackson, Michigan. In any event, there appeared to be a spontaneous outpouring of anger following passage of the Kansas-Nebraska Act. Large public meetings were held in numerous Northern communities, some of which used the term “Republican.” The ranks of the emerging Republican Party were filled by the following:
• Northern Whigs united in their opposition to the Kansas-Nebraska Act, but leaderless following the deaths of Henry Clay and Daniel Webster, both in 1852
• The Free-Soil Party, which had played a spoiler role in several presidential elections, but now was bereft of effective leadership
• The Know-Nothing movement, whose roots lay in the fear of immigrants in general and Roman Catholics in particular
• Northern Democrats who deserted their Southern cousins over the slavery issue.
The party was strongly influenced in its early years towards the idea of liberal capitalism, in opposition to the monopoly capitalism of the National Republican wing of the Whig party. Among the supporters of this position were Whigs like William Seward and Horace Greeley and Democrats like William Cullen Bryant and Preston King. Despite the claim of the modern Democratic Party to be the inheritors of the philosophy of Thomas Jefferson, the originators of the Republican Party considered Jefferson also to be one of their guiding lights, partly because he had been influential in keeping slavery out of the territories that were covered by the Northwest Ordinance of 1787. In addition, they drew on the ideas of Alexander Hamilton. The new party experienced almost overnight success, winning control of the House of Representatives in the fall of 1854. Issues that brought the Republicans together included:
1. Repeal of the Kansas-Nebraska Act—the Republican opposition to the extension of slavery was based more on economic concerns than moral ones
2. Support of the central route for the construction of the transcontinental railroad
3. Support of a Homestead Acts, which would ease the process for settlers to own western lands
4. Support of high protective tariffs and liberal immigration laws—both were attractive to Northern manufacturers.
Importantly, the Republicans were the party of free working white men; they were opposed to the spread of slavery because they did not want to compete against unpaid labor in the lands opening in the West. They were no particular friends of the blacks, slave or free. Further, the Republicans were purely a sectional party; they did not attempt to run candidates in the slave states. Their plan was to gain complete political control in the North; if they did, they would have sufficient electoral strength to elect a president.
They vigorously argued that free-market labor was superior to slavery and the very foundation of civic virtue and true republicanism. “Free soil, free labor, free speech, free men” was coined when John C. Fremont was nominated for President by the new Republican Party in 1856. (Read the Republican Platform of 1856 )
Even though Republicans were a ‘third party’ in a two party system of Democrats and Whigs, Fremont received 1/3 of the vote.
Four years later, Abraham Lincoln became the first Republican to win the White House in 1860.
The Civil War erupted a year later. During the war Lincoln signed the Emancipation Proclamation that freed the slaves. The Republicans of the day worked to pass the Thirteenth Amendment, which outlawed slavery, the Fourteenth, and Fifteenth Amendments which guaranteed equal protection under the law and secured voting rights.
The Republican Party played a leading role in securing women the right to vote. In 1896, Republicans were the first party to favor women’s suffrage. When the 19th Amendment finally was added to the Constitution, 26 of 36 state legislatures that had voted to ratify it were under Republican control. The first woman elected to Congress was a Republican, Jeanette Rankin from Montana in 1917.
Today the Republican Party still stands for the individual to have a life, liberty and pursuit of happiness.
Individual Rights
The Republican Party is the Party of Liberty and the Constitution. To live in a civilized society, man only requires one thing from his fellow man and that is the freedom of action. Man requires rights to those actions necessary to support his own life. The most fundamental right is the right to life, from which all other rights, including the right to liberty, property, and the pursuit of happiness, derive. These rights are given to us by our Creator (unalienable rights).
The Republican Party works to secure the Blessings of Liberty for all individuals through the principles premised in the Declaration of Independence. These principles are protected by the U.S. Constitution and the Bill of Rights. Your unalienable (God-given) rights cannot be taken away or given by Government.
Limited Government and Sovereignty
The Republican Party stands firm on the issue of Limited Government. The United States of America is a Constitutional Republic. Government was intended by the Founders of our great Republic to be limited. The Constitutional Convention for the “Bill of Rights” expressed a desire to prevent misconstruction or abuse of its power and further restrictive clauses were added. The Federal Government is enumerated with specific powers and the rest are retained by the States and the People.
The Republican Party also stands firm on the issue of Sovereignty, as our Founding Fathers envisioned! The United States Constitution does not delegate sovereignty to the United Nations, U.N. Resolutions or any other Foreign Government Authority. Many died in the War of Independence and have died in Wars protecting our Liberty. The Republican Party honors those whom have given their lives for Liberty.
Government holds the sole monopoly on force. Therefore, Government is intended by the Founding Fathers to use force, according to objectively defined laws, only to “protect” your person and property against those who initiate force against you.
Separation of Powers
The United States Constitution clearly separates the power of the Legislative, Executive and Judicial Branches. It assures that all Americans stand equal before the law, including those whom represent us. In the Union, the States are Sovereign with limited Federal power over them. The founders of our Republic had the foresight to balance the powers of Government so that no one branch of Government would infringe on the other or monopolize and centralize power. Separation of Powers secures the Blessings of Liberty. The Republican Party aligns itself with these values.
Economic and personal liberties are moral issues. Rights are unalienable and they may not be morally infringed upon. Rights are not guarantees to things, but only guarantees the freedom of action – right to liberty, and a guarantee to the results of those actions – right to property. A free people use voluntary exchange as the force behind prosperity. An economy based on sound money and keeping the fruits of your labor provides the long term security for business, Government, families and individuals.
National Defense and Foreign Policy
Peace through strength. The U.S. Constitution enumerates the power for a Common Defense against foreign and domestic enemies. A strong National Defense secures the Blessings of Liberty. A Constitutional Foreign Policy provides for such actions as the Declaration of War, Letters of Marque and Reprisal and Treaties. The U.S. Constitution does not delegate sovereignty to the United Nations or U.N. Resolutions.
Examples of a strong national defense will include border security and ILLEGAL immigration control. It also includes a well trained, well funded military to include rules of engagement to overthrow the enemy rather than endanger the men and women in uniform. It also includes the exclusion of documented and known domestic/foreign enemies and enemy sympathizers in Government, law enforcement, military and intelligence agencies.
Social Issues
We hold these Truths to be self-evident that all human kind is created equal. Honoring the freedom and liberty of individual beliefs and traditions provide for a foundation for domestic tranquility. Human life in all forms is not the province of federal government force and coercion.
The Republican Party respects moral issues because they are the foundation of any civilized society. A society without moral standards collapses as proven throughout history. Our Founding Fathers understood this and in many places stated that their ideals were grounded in Biblical Religion. As a result, The Republican Party respects and honors the same since it is our Founding history.
The Republican Party rejects all collectivist ideologies and Fascist models. They are models for Tyranny, which infringe on Liberty and the unalienable rights of the individual.
Bipartisanship is not possible when the ideals of liberty and the collectivist ideals are in play. It is only when parties can agree on liberty based issues rather than collectivist based issues that bipartisanship can be achieved.

Time will tell: Secular change in metamorphic timescales and the tectonic implications
Chowdhury, P. and Chakraborty, S. and Gerya, T.V.
Volume: 93 Pages: 291-310
DOI: 10.1016/
Published: 2021
The pressure-temperature-time (P-T-t) evolution of metamorphic rocks is directly related to geodynamics as different tectonic settings vary in their thermal architecture. The shapes of P-T paths and thermobaric ratios (T/P) of metamorphic rocks have been extensively used to distinguish different tectonic domains. However, the role of metamorphic timescales in constraining tectonic settings remains underutilized. This is because of the poorly understood relationship between them, and the difficulty in accurately constraining the onset and end of a particular metamorphic event. Here, we show why and how the intrinsic relationship between thermal regime, rheology and rate of motion controlled by the heat, mass and momentum conservation laws translate to differences in heating, cooling, burial, exhumation rates of metamorphic rocks and thereby, to the duration of metamorphism. We compare the P-T-t paths of the orogenic metamorphic rocks of different ages and in particular, analyse their retrograde cooling rates and durations. The results show that cooling rates of the metamorphic rocks are variable but are dominantly <50 °C/Ma during most of the Precambrian before increasing by an order of magnitude (>100 °C/Ma) during the late Neoproterozoic to Phanerozoic. To seek what controlled this secular change in metamorphic cooling rates, we use thermomechanical modelling to calculate the P-T-t paths of crustal rocks in different types of continental orogenic settings and compare them with the rock record. The modelled P-T-t paths show that lithospheric peel-back driven orogenic settings, which are postulated as an orogenic mode operating under the hotter mantle conditions of late Archean to early Proterozoic, are characterised by longer durations of metamorphism and slower cooling rates (a few 10s of °C/Ma) as compared to the modern orogenic settings (a few 100s of °C/Ma) operating under relatively colder mantle conditions. This is because peel-back orogens feature: (1) hot lithospheres with very high crustal geotherms being sustained by high mantle heat-flow and profuse magmatism, and (2) distributed deformation patterns that limit vertical extrusion (exhumation) of the metamorphic rocks along localized deformation zones and instead, trap them in the orogenic core for a long time. In contrast, modern orogens mostly involve colder lithospheres and allow rapid exhumation through localized deformation, which facilitates faster cooling of hot, exhumed metamorphic rocks in a colder ambience. Thus, we propose that the secular change in metamorphic cooling rates indicates a changing regime of orogenesis and thereby, of plate tectonics through time. Predominance of the slower metamorphic cooling rates before the Neoproterozoic indicate the occurrences of peel-back orogenesis and truncated hot (collisional) orogenesis during that time, while the appearance of faster cooling rates since the late Neoproterozoic indicates the transition to modern style of orogenesis. A transition between these orogenic styles also accounts for the prolonged longevity (>100 million years) of many Precambrian orogenic belts as compared to the Phanerozoic ones. This study underscores the strength of timescales in combination with P-T paths to distinguish tectonic settings of different styles and ages. © 2021 International Association for Gondwana Research

Einstein’s Gravity
From Science News comes a captivating anthology of articles exploring the concept of gravity and Albert Einstein’s enduring influence on the way humans understand it.
From the ancient Greeks to Galileo to Sir Isaac Newton, gravity has long fascinated scientists and laypeople alike. One of the most mysterious forces in the universe, gravity as a theory has developed and changed over the centuries, but no single person has had as much to do with its evolution, and our understanding, as Albert Einstein.
This collection of articles from the Science News archive looks at Einstein’s development of the general theory of relativity and considers its impact. Thanks to his revisions of Newton’s theories, we have come to predict and understand phenomena such as gravitational waves, black holes, and the expansion of the universe. But Einstein did not just provide explanations—his work has raised new questions that scientists continue to investigate today.

Vril Society
(redirected from Vril)
Also found in: Dictionary, Wikipedia.
Enlarge picture
Karl Haushofer founded the Brothers of the Light Society, which became the Vril Society.
Vril Society
This German secret society believed that whoever possessed the Vril force could conquer the world and meet the master race from the earth’s interior as equals.
In 1871, when the occultist Edward Bulwer-Lytton wrote a novel about a small group of German mystics who had discovered the truth about a race of supermen living within the earth’s interior, he inspired the founding of the Brothers of the Light, the Luminous Lodge, the Vril Society. Bulwer-Lytton’s The Coming Race told the story of an advanced civilization of giants who thrived in the inner earth. The superrace had built a paradise based on the Vril force, a form of energy so powerful that the older beings had outlawed its use as a potential weapon.
In 1919 Karl Haushofer, a student of the Russian mystic George Gurdjieff, founded the Brothers of the Light Society in Berlin and soon changed its name to the Vril Society. As Haushofer’s Vril grew in prominence, it united three major occult societies, the Lords of the Black Stone, the Black Knights of the Thule Society, and the Black Sun and chose the swastika, the hooked cross, as its symbol of the worship of the Black Sun. While these societies borrowed some concepts and rites from Theosophists, Rosicrucians, and various Hermetic groups, they placed special emphasis on the innate mystical powers of the Aryan race. The Vril and its brother societies maintained that Germanic/Nordic/Teutonic people were of Aryan origin, and that Christianity had destroyed the power of the Teutonic civilization.
In 1921 Maria Orsic (or Orsitsch), a medium in the Vril Society, began claiming spirit messages originating from Aryan aliens whose home star was Aldebaran. Orsic and another medium, Sigrun, learned that the aliens spoke of two classes of people on their world—the Aryan master race and a subservient planetary race that had evolved through mutation and climate changes. A half billion years ago the Aryans, also known as the Elohim or Elder Race, began to colonize our solar system. On Earth, the Aryans were identified as the Sumerians until they elected to carve out an empire for themselves in the hollow of the planet. The Vril force was derived from the Black Sun, a large ball of “Prima Materia” that provided light and radiation to the inhabitants of the inner earth.
The Vril Lodge believed that whoever learned control of the Vril would become master of himself, those around him, and the world itself, if he should so choose. This ancient force had been known among the alchemists and magicians as the Chi, the Odic force, the Orgone, and the Astral Light, and the members of the Vril Society were well aware of its transformative powers to create supermen out of ordinary mortals. Such members of the lodge as Adolf Hitler, Heinrich Himmler, Hermann Göring, Dr. Theodor Morell (Hitler’s personal physician), and other top Nazi leaders became obsessed with preparing German youth to become a master race so that the Lords of the inner earth would find them worthy above all others when they emerged to evaluate the people of Earth’s nations.
In 1922, members of Thule and Vril built the Jenseitsflugmaschine, the Other World Flight Machine, based on the psychic messages received from the Aldebaran aliens. W. O. Schumann of the Technical University of Munich was in charge of the project until it was halted in 1924; the craft was then stored in the Messerschmitt aircraft company’s Augsburg facility. In 1937, after Hitler came into power, he authorized the construction of the Rundflugzeug, the “round or disk-shaped vehicle,” for military use and for spaceflight.
In April 1942 Nazi Germany sent out an expedition composed of a number of its most visionary scientists to seek a military vantage point in the Hollow Earth. Although the expedition of leading scientists left at a time when the Third Reich was putting maximum effort into the drive against the Allies, Göring, Himmler, and Hitler are said to have enthusiastically endorsed the project. Steeped in the more esoteric teachings of metaphysics, the führer had long been convinced that Earth was concave and that a master race lived on the inside of the planet.
The Nazi scientists who left for the Baltic island of Rugen had complete confidence in the validity of their quest. In their minds, such a coup as discovering the opening to the inner world would not only provide them with a military advantage, but go a long way in convincing the masters who lived there that the German people truly deserved to mix their blood with them in the creation of a hybrid master race to occupy the surface world.
Students of the Vril Society also insist that aliens worked with Nazi scientists to create early models of flying saucers. The UFO researcher Vladimir Terziski believes that an “alien tutor race” secretly began cooperating with certain German scientists from the Thule, the Vril, and the Black Sun in the late 1920s. Working in underground bases with the alien intelligences, Terziski says, the Nazis mastered antigravity space flight, established space stations, accomplished time travel, and developed their spacecraft to warp speeds.

There is no state coercion of any kind; instead, convention and custom govern the lives of the Vril-ya thanks to their ability to self-discipline their behavior through the aid of Vril. All the Vril-ya put the common good before all other considerations, thus producing an authoritarian order in which a single magistrate rules, albeit with no formal coercive power, and citizens abide by the motto "No happiness without order, no order without authority, no authority without unity;" Language such as this calls to mind the totalitarian dystopias of George Orwell's 1984 or Alan Moore's V for Vendetta.
Gradually, however, he becomes critical of their power and values as well as increasingly aware that he cannot ever participate in their society--he is biologically incapable of controlling vril or the Vril staff, and is thus permanently excluded and inferior.
One of the oddities of the 19th-century utopias was Edward Bulwer-Lytton's The Coming Race (1871) in which each person had a power, called 'vril', which could be used to instantly annihilate another person.
Named Vril, the colt is out of Phantom Creek, a daughter of Mr Prospector and a half-sister to champion juvenile Arazi and top-class miler Noverre.
And yet, while these positive images of a brave new world spilled through into the nineteenth century--with authors like Jules Verne (An Ideal City) Edward Bulwer-Lytton (Vril, The Power of the Coming Race) and Edward Bellamy (Looking Backward) perceiving prosperity and order as the ultimate fate of an increasingly technological society-the apocalyptic spirit of St John had never entirely gone away.
They live in a sort of perfect matriarchy that nonetheless has decided to allow the men to run things, and they possess a secret invisible power called Vril, which seems to be--surprise!--a form of electricity.
Peer counseling, information and referral, and skills training are some of the services provided under the VRIL contract.

[(essay date April 1997) In the following essay, Drout explores Cooper's use of Anglo-Saxon source materials for her creation of the The Dark is Rising sequence.]
Legendary, mythological, and historical materials have long been sources for English literature, and the study of the ways sources are adapted has been a significant aspect of critical practice. One of the standard assumptions of source study is that sources carry their histories with them, and therefore readers encountering legendary or historical materials are able to supply a fuller context for the reference from their existing cultural knowledge. Part of literary-critical practice for the past hundred years has been the explication of such references and the attempt to understand and explain the contexts they bring to bear. Such work is most evident in the study of ancient and medieval cultures, where it focuses on the recovery of lost contexts, but it can also be found, for example, in the work of Joyce-scholars attempting to unwind the layers of multilingual references in Finnegans Wake.
There are serious theoretical objections to the reflexive practice of source study, the most obvious being that source-based interpretations privilege the experiences of a particular (and perhaps privileged) group of readers who possess the context to which a reference metonymically refers. This objection is strengthened in the case of source-study of children's literature. Whereas it is reasonable to assume that adult readers possess at least a modicum of the shared cultural context necessary to ensure communication through reference, the intended readers of children's books are likely to be encountering many references for the first time. Presumably they do not have what E. D. Hirsch calls the "cultural literacy" (10-18) to reconstruct a reference from an allusion. Nor may they be sophisticated enough to understand fully the idea that the adaptation of a source is equivalent to its modification, or that adaptations often work to fix ambiguous meanings. What would appear to an adult reader or critic as the adaptation of source material would seem to be to many (particularly younger or less acculturated) child readers either authorial invention or, more problematically, factual history.
Source study would therefore seem to be an unrewarding approach to the analysis of children's literature. Such study privileges one sort of reader, the informed, educated critic, at the expense of another, the less educated (perhaps naive) child and replicates in discourse the sorts of vertical power relations stereotypical of the interactions between adults and children. These sort of objections are reasonable, and I do not intend to refute them in this paper. I hope to demonstrate, however, that examination of the sources for a certain type of children's literature can be a fruitful critical practice. I will argue the counterintuitive proposition that even though children cannot be expected to reconstruct the cultural context of historical and mythological allusions, these allusions--or, more accurately, the allusions intertwined with their previous political appropriations--fundamentally shape the text beyond the control of the author and beyond the conscious apprehension of the...

Population biology and larval ecology of the sea urchin Centrostephanus rodgersii (Agassiz 1863) in New Zealand under the influence of global climate change
The ocean has absorbed about one third of the total anthropogenic emissions of CO2 since 1800 and, consequently, global mean surface ocean pH has decreased of approximately 0.1 pH unit. This variation of atmospheric CO2 is also correlated with decadal increases in average global temperature by 0.13°C since 1956. Atmospheric CO2 levels are rising annually of 0.5%, and, if emissions are not reduced, a further decrease of 0.14-0.41 and 0.30-0.7 pH units by 2100 and 2300 respectively is expected, in a process called “ocean acidification”. A concurrent average sea surface temperature increase of 2-4°C is predict by 2100, as another aspect of global climate change defined as “global warming”. Temperature and pH are known to affect physiology and early development of marine invertebrates and, in the case of temperature, also geographical distribution.
This thesis examines larval and population biology of the echinoid Centrostephanus rodgersii at the Mokohinau Islands, New Zealand, under global climate change. Its growth, population size and age structure and gametogenetic cycle in this region were studied and compared to populations in mainland Australia and Tasmania. The effects of temperature and pH on early life stages of C. rodgersii were compared with those of Evechinus chloroticus and P. huttoni, two echinoids endemic to New Zealand, to provide the first overview of the responses of sea urchins to global climate change in New Zealand. The effect of these variables on the embryos and larvae and the implications of this on the distribution of these species in New Zealand in warmer and more acidic future scenarios are then discussed. C. rodgersii at the Mokohinau Islands is also compared with a population in Coffs Harbour, New South Wales, to assess the potential of this species for early adaptation to a new environment.
C. rodgersii was found to grow at a slightly faster pace than the populations in Tasmania and population size and age structure suggest that recruitments occurs regularly. The timing of the gametogenetic cycle is similar to a population from Sydney and spawning takes place between late July and September. Thermal tolerance of fertilisation was very broad in all the species considered, and the process was practically unaffected by temperature. The optimal thermal range was similar through the subsequent developmental stages and was ≈16–23°C for C. rodgersii at the Mokohinau Islands, ≈17–24°C for C. rodgersii at Coffs Harbour, ≈12–18°C for E. chloroticus and ≈12–17°C. These thermal tolerances for development of C. rodgersii agree closely with its present day distribution in New Zealand, suggesting the distribution range is largely controlled by temperature dependant recruitment in this species. Fertilisation was slightly (<10%) reduced in all species by pH conditions predicted by 2100 and no buffering effect of temperature was found. A 3°C temperature increase was either neutral or beneficial for subsequent developmental stages in E. chloroticus and C. rodgersii (Mokohinau Islands), it did not affect C. rodgersii (Coffs Harbour) and was neutral or negative for P. huttoni. Lowered pH had a general negative effect, which was always minor, compared to the effect of increased temperature. Larval morphology was affected by lowered pH differently in the three species considered. Pluteus larvae showed either shorter arms (both populations of C. rodgersii and E. chloroticus) or smaller larvae with shorter arms and an altered global morphology (P. huttoni).
This study found that the effects of increased temperature and decreased pH are species-specific. It strengthens the idea that temperature is the main stressor of the early life stages and that it often contradicts the effects of pH. Global organismal responses are, therefore, hard to predict. This study also suggests that embryos and larvae of C. rodgersii in New Zealand are, at present, in suboptimal conditions and that a temperature increase could favour the extension of its geographical range to other areas, despite the negative effects of lowered pH. Further research is needed to detail distribution of C. rodgersii in New Zealand and to clarify potential interactions with E. chloroticus. Physiological measurements on embryos and larvae reared in near future scenarios are also recommended to highlight sublethal effects.

Economic impacts of Covid
Image source: The Hindu
The Coronavirus is a global health crisis that is having devastating effects on global economic activities as a whole. Most of the countries locked themselves which led to a slowdown of the economy, lockdowns damaged economies worldwide. Domestic demand and exports hit a sharp fall during the pandemic. Most of the economies faced and some are still facing Recession, though with some exceptions. This has impacted the white-collar and blue-collar workers. Many sectors have seen negative growth while few sectors have seen unprecedented positive growth rate. This has resulted in vast inequalities. According to a United Nations report, youth are the largest poverty-stricken group. A survey for BBC suggests that the coronavirus pandemic has hit the poorer countries harder than the rest of the world, sowing inequality globally. Drop in income was 69% in poor countries in comparison to 49% in rich countries. Unemployment rates have rocketed across major economies. Despite the development of new vaccines, many are still wondering what recovery could look like.
The pandemic contributed to the impacts in various sectors.
(a). Food and agriculture: The limited mobility of people across the borders and lockdowns resulted in a labour shortage in agriculture in various countries, leading to reduced production. The disease doesn’t affect the natural resources upon which production is based, therefore the direct impact on primary agriculture is limited. The government of India provided various relief measures to help farmers, like the removal of tax barriers on exports.

(b). Aviation and tourism: The pandemic hit these sectors harder than 9/11 and the financial crisis of 2008. With travel restrictions across the world, the demand for turbine fuel substantially declined.
(c). Pharmaceuticals: This is showing an upward trend since covid started. The export of Hydroxychloroquine to the world has raised considerable demand. Pharma industries struggled because the government imposed a ban on the exports of drugs. The increase in demand and decrease in accessibility is the worst combination during this time.
Many such sectors are being affected by the pandemic. A decrease in demand has increased the unemployment rate and disproportionately affects the poor and the vulnerable sections of society. The deaths caused by the pandemic left many families in misery. The Wholesale Price Index [WPI] Inflation jumped double-digit.
Way forward
It is high time to find a way to balance the demand side shocks induced by potential lockdowns and other ongoing containment measures. Countries like India have a more fragile economic and social fabric and the present situation will create more suffering for unorganised sectors and migrant labour. Government must manage multiple demands – responding to health crises, managing the consequences of the shock of the economy, ensuring the smooth functioning of the food system. Adopting new principles like the shift towards localization, cash conservation, supply chain resilience and innovation will help businesses in treading a new path in this uncertain environment.

This evening, the Illinois House passed Senate Bill 2090. The bill requires county jails and election authorities to collaborate in creating a process that ensures pre-trial detainees in jail can cast their ballot during elections. The bill also assures that eligible citizens leaving Illinois prisons and jails receive a voter registration application and information about their voting rights being restored.
“Across the country, there have been countless measures passed to make it harder for people to vote. With the passage of SB 2090, we will ensure that every eligible citizen leaving jails and prisons in Illinois know about their right to vote. If returning citizens don’t know about their right to vote, they are much less likely to exercise those rights – and it’s an essential part of democracy.
Thank you to House sponsor Representative Welch for his commitment to this issue and leadership in getting this legislation through. We look forward to Senate Bill 2090 being signed into law by Governor Pritzker.”

#FunFactFriday: Did you know that the Spring Mountains are considered a Sky Island? The term “sky island” is used to describe an isolated mountain range with drastic elevation changes and diverse life zones, which is surrounded by a lowland environment “sea”. In our case, the surrounding Mohave Desert isolates the mountain, similar to how oceans isolate pieces of land. In the picture below, you can see the radical changes as you move from the valley floor up to the mighty pine trees.

Tips for reducing gas and flatulence
Are you inconvenienced by flatulence? Although the digestive tract produces gas naturally, there are simple ways to reduce their significance.
Flatulence is caused by an accumulation of gas in the stomach or the intestine. This can cause bloating accompanied by the expulsion of gas through the anus. Burping is another way to release excessive gas in the digestive tract.
Although gas may be unpleasant, it is rarely indicative of a serious health problem. In fact, it is completely normal to have some. It is estimated that men and women generally pass wind about 12 to 25 times a day. Some people believe that this reflects poor health, but this isn’t the case at all!
The amount of gas eliminated per day depends on several factors, mainly air ingestion and the activity of bacteria in the intestine.
An important source of gas is the consumption of complex sugars that are not transformed into absorbable sugars. When these sugars go through the intestine, they are broken down by intestinal bacteria that use them as food and later produce gas.
Food rich in complex sugars
Peanut Cauliflower Lentil
Bagel Cucumber Corn
Barley Oat flour Onion
Beet Sesame flour Whole grain bread
Peanut butter Soybean Pasta
Wheat Red kidney bean Parsley
Brocoli Oatmeal Pea
Carrot Soy milk Chickpea
Cabbage Lettuce Rye
Brussels sprout Fried vegetables Tofu
Soft drinks and beer are another major source of flatulence. These products contain a lot of gas, as you can see by the amount of bubbles. Additionally, some gas bubbles are formed while drinking the beverage and are thereby swallowed.
Air ingestion
Air is frequently ingested while eating, drinking and swallowing saliva. This occurs even more often in the presence of certain factors: respiratory difficulties (e.g., nasal congestion), poorly adjusted dental prostheses, habitually eating fast or gulping down food, etc.
Various practices or habits can also increase the amount of air ingested, including:
• smoking
• chewing gum
• drinking with a straw
• sipping small amounts of hot fluids
Health problems
Health issues can sometimes cause digestive symptoms such as bloating and flatulence. This is the case for certain food intolerances, including lactase deficiency (or lactose intolerance). Those who suffer from it are unable to adequately digest lactose, a natural sugar present in milk and dairy products.
The lactose is fermented due to the activity of bacteria in the intestine, causing gas and other symptoms such as diarrhea, abdominal cramps and pain. If you have a lactase deficiency, you can avoid dairy products or take lactase enzyme supplements (these products can be purchased at the pharmacy without a prescription).
Constipation often leads to bloating and flatulence. Intestinal diseases (e.g., irritable bowel syndrome, Crohn’s disease, ulcerative colitis, etc.) or other illnesses (e.g., celiac disease, diabetes, scleroderma) can also be involved.
The prevention of flatulence
Adopting simple habits can reduce the risk of bloating and flatulence:
• Avoid beer and carbonated beverages.
• Avoid talking while eating.
• Avoid chewing gum.
• Avoid food rich in complex sugars.
• Avoid drinking while eating.
• Avoid or reduce consumption of sugar substitutes (sorbitol or fructose).
• Take the appropriate measures to avoid constipation.
• Exercise regularly.
• Learn to better manage stress.
• Quit smoking.
In order to treat an intestinal gas issue, it is essential to know the causes and to try to resolve the problem. When gas is minor or transient, it can be prevented or relieved by using over-the-counter medication.
Simethicone (Ovol®, etc.) can be taken during or after meals to prevent or relieve bloating and flatulence. It quickly breaks down gas bubbles trapped in the intestine. Under the effect of this medication, the bubbles merge, helping to eliminate gas more easily.
The alpha-galactosidose enzymes (Beano®, for example) must be taken with the first bite of a meal. These enzymes break down complex sugars that cause gas. Therefore, these enzymes will only be effective when gas is caused by unabsorbed complex sugars.
Don’t hesitate to speak to your pharmacist for additional information about bloating and flatulence.

Learning differences
People ask where do learning differences come from and there are labels such as, learning disabilities or dyslexia or attention deficit disorder. Every single human being has a matrix of skills. Somethings they're really efficient at, some they're medium at and some they're inefficient at. And that is just being a human being. And so if we can just understand how we learn, if we can understand what the mathematics problem or the writing skill is needed and then we can also say this child is really strong in their memory skills or not, then we can teach so that you can learn almost everything. It's understanding what you have to learn, how the brain works and how as a teacher can I create a combination of all of those skills to really have a successful learning experience for every person.

Evolutionary biology
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. Simply, it is also defined as the study of the history of life forms on Earth. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. A person who studies Evolutionary biology is called an Evolutionary biologist.[1] The importance of studying Evolutionary biology is mainly to understand the principles behind the origin and extinction of species.
Evolution is the central unifying concept in biology. Biology can be divided into various ways. One way is by the level of biological organization, from molecular to cell, organism to population. An earlier way is by perceived taxonomic group, with fields such as zoology, botany, and microbiology, reflecting what was once seen as the major divisions of life. A third way is by approaches, such as field biology, theoretical biology, experimental evolution, and paleontology. These alternative ways of dividing up the subject can be combined with evolutionary biology to create subfields like evolutionary ecology and evolutionary developmental biology.
More recently, the merge between biological science and applied sciences gave birth to new fields that are extensions of evolutionary biology, including evolutionary robotics, engineering,[3] algorithms,[4] economics,[5] and architecture.[6] The basic mechanisms of evolution are applied directly or indirectly to come up with novel designs or solve problems that are difficult to solve otherwise. The research generated in these applied fields, in turn, contributes to progress, especially thanks to work on evolution in computer science and engineering fields such as mechanical engineering.[7]
Evolutionary developmental biology
In evolutionary developmental biology the different processes of development can play a role in how a specific organism reaches its current body plan. The genetic regulation of ontogeny and the phylogenetic process is what allows for this kind of understanding of biology to be possible. Looking at different processes during development, and going through the evolutionary tree, one can determine at which point a specific structure came about. For example, the three germ layers can be observed to not be present in cnidarians and ctenophores, which instead present in worms, being more or less developed depending on the kind of worm itself. Other structures like the development of Hox genes and sensory organs such as eyes can also be traced with this practice.[8]
Microbiology too is becoming an evolutionary discipline, now that microbial physiology and genomics are better understood. The quick generation time of bacteria and viruses such as bacteriophages makes it possible to explore evolutionary questions.
Many biologists have contributed to shaping the modern discipline of evolutionary biology. Theodosius Dobzhansky and E. B. Ford established an empirical research programme. Ronald Fisher, Sewall Wright, and J. S. Haldane created a sound theoretical framework. Ernst Mayr in systematics, George Gaylord Simpson in paleontology and G. Ledyard Stebbins in botany helped to form the modern synthesis. James Crow,[10] Richard Lewontin,[11] Dan Hartl,[12] Marcus Feldman,[13][14] and Brian Charlesworth[15] trained a generation of evolutionary biologists.
Current research topics
First, some fields of evolutionary research try to explain phenomena that were poorly accounted for in the modern evolutionary synthesis. These include speciation,[16][17] the evolution of sexual reproduction,[18][19] the evolution of cooperation, the evolution of ageing,[20] and evolvability.[21]
Second, biologists ask the most straightforward evolutionary question: "what happened and when?". This includes fields such as paleobiology, as well as systematics and phylogenetics.
Fourth, the modern evolutionary synthesis involved agreement about which forces contribute to evolution, but not about their relative importance.[24] Current research seeks to determine this. Evolutionary forces include natural selection, sexual selection, genetic drift, genetic draft, developmental constraints, mutation bias and biogeography.
An evolutionary approach a is key to much current research in organismal biology and ecology, such as in life history theory. Annotation of genes and their function relies heavily on comparative approaches. The field of evolutionary developmental biology ("evo-devo") investigates how developmental processes work, and compares them in different organisms to determine how they evolved.
Drug resistance today
Evolution plays a role in resistance of drugs. For example, how HIV becomes resistant to medications and the body's immune system. The mutation of resistance of HIV is due to the natural selection of the survivors and their offspring. The one HIV that survived the immune system reproduced and had offspring that were also resistant to the immune system.[26] Drug resistance also causes many problems for patients such as a worsening sickness or the sickness can mutate into something that can no longer be cured with medication. Without the proper medicine, a sickness can be the death of a patient. If their body has resistance to a certain number of drugs, then the right medicine will be harder and harder to find. Not finishing an antibiotic is also an example of resistance that will cause the bacteria or virus to evolve and continue to spread in the body.[27] When the full dosage of the medication does not enter the body and perform its proper job, the virus and bacteria that survive the initial dosage will continue to reproduce. This makes for another sickness later on that will be even harder to cure because this disease will be resistant to the first medication used. Finishing medicine that is prescribed is a vital step in avoiding antibiotic resistance. Also, those with chronic illnesses, illnesses that last throughout the lifetime, are at a greater risk to antibiotic resistance than others.[28] This is because overuse of a drug or too high of a dosage can cause a patient's immune system to weaken and the illness will evolve and grow stronger. For example, cancer patients will need a stronger and stronger dosage of medication because of their low functioning immune system.[29]

Lease Period Rental Agreement
| 0
If flexibility is your goal, a monthly lease is the right way to going. For example, in uncontrolled areas in California, either a landlord or a tenant can terminate a monthly lease with a period of 30 days or 60 days in advance if the tenant has lived in the unit for a year or more. A terminable lease (UK: determinable/fragile lease) is a lease agreement that can be terminated exclusively by the lessee or exclusively by the lessor without penalty (formally fixed). A mutually identifiable lease agreement can be determined by both. A non-cancellable lease is a lease agreement that cannot be terminated in this way. Generally, „leasing“ may involve a non-cancellable lease, while „lease“ may mean a cancellable lease.

Eli's Script
So Eli has writen a script. Its called War Born and its a great read. You can pull it up here http://studios.amazon.com/projects/69271 You can leave a review here.
After a hundred years of war two clans, the Ninja and the Samurai, have exhausted themselves. A neighboring merchant class country moderated as the clans agreed to a treaty. The treaty guarantees peace until one unborn child from each clan are born, trained for combat, deemed worthy, then hunt each other till one stands. Complications arise when Crow, the Samurai’s War Born, values the peace that the treaty has provided over victory.

How do I change the House and Unit Code for my Sentinel camera?
You use the remote to program the Sentinel camera with a House and Unit code. By default, the C1-C4 buttons on the CR15A remote default to the X10 addresses of A1-A4.
Programming a House and Unit Code Into the Camera
1. Pick the camera you wish to set a House and Unit code for. Follow the instructions at the beginning of the manual to set it up.
2. Set the mode switch on the bottom of that camera to Program.
3. Press one of the C1-C4 buttons on your remote control to set this camera's address.
4. Set the mode switch back to Transmit Enable.
Repeat these steps for the rest of the cameras.
Changing the House Code for the Remote
The Camera and Remote come set to House Code A by default. To change the House Code on the remote follow steps 1 through 4 below:
1. Press and release the X10 button (red indicator flashes).
2. Press and hold Setup until the red indicator lights steadily. Release the Setup button.
3. Use the number buttons to enter the number equivalent to the chosen Housecode (1=A, 2=B....16=P).
4. Press the Setup button to confirm the Housecode. The red indicator blinks to indicate the code set, (twice for B, three times for C, etc.), then turns off.
Changing Unit Codes for Buttons C1, C2, C3, and C4
The Sentinel Remote comes set to control cameras set to units 1 through 4. If you want to set your Sentinel Cameras to different Unit Codes, follow these steps to reprogram the remote:

Jigsaw overview
PSHE enables our children to become healthy, independent and responsible members of society. It aims to help them understand how they are developing personally and socially, and tackles many of the moral, social and cultural issues that are part of growing up. We provide our children with opportunities for them to learn about rights and responsibilities and appreciate what it means to be a member of a diverse society. Our children are encouraged to develop their sense of self-worth by playing a positive role in contributing to school life and the wider community.
PSHE contributes to our whole school ethos, to safeguarding our children and to spiritual, moral, social and cultural education. The teaching of PSHE should be weekly and structured to support pupils to explore their feelings and relationships in a safe, secure environment.
To implement our intent, as a school we build our PSHE / RSE teaching around the Jigsaw 3-11 programme.

The most fundamental of Hindu deities, is the Trinity of Brahma, Vishnu and Shiva - popular deities include Ganesha, Krishna, Hanuman and goddesses like Lakshmi, Durga,Saraswati.
Goddess Kamakshi
The goddess Kamakshi is a form of Tripura Sundari or Parvati or the universal mother goddess. The main abode of Kamashi is the Kamakshi Amman temple at Kanchipuram. Kamakshi is the presiding deity of the city of Kanchi.
The Goddess is called as "Sri Kamakshi. The word is derived from the heritage "Ka" means Goddess Saraswati (God of Education), "Ma" means Goddess Lakshmi (God of Wealth), "Akshi" means Eye. The name as a whole refers as the god lives in Kanchi with Goddess Saraswati and Goddess Lakshmi as her both eyes. The Lalitha Sahasranama poem is an idle example for the goddess power.
Goddess Kamakshi is considered to be the representation of Shri Vidya - Shri Lalita Maha Tripurasundari - she reigns supreme in Kanchi. The Goddess is said to reside as Bala Tripurasundari in a Bila (niche) situated under the shrine. The front mandapa is called the Gayatri Mandapa.In the Ardha Mandapa preceding the Garbhagriha, the Goddess is enshrined in a pitha, as Sri Vidya Parameswari.

SLSD Subrecord
==SLSD/SCVR SubrecordSubrecords==
SLSD and SCVR records together represent the local variables of the script. SLSD provides general info, while SCVR gives the name of the variable.
Appears to hold 24 bytes (confirmed) of data related to a local variable definition.
AppearsSLSD appears to hold 24 bytes (confirmed) of data related to a local variable definition.
{| class="greylapse" border="1" width="100%"
| Index
| 4 (dword)
| Unique index for each local variable in the script (not confirmed)? Does not follow the order of variable declaration.
| Unknown
SLSD/SCVR pairs appear in the order in which they're defined in the script at compile time. When compiling a script, the compiler will use index already assigned to the variable if it already exists in the SLSC/SCVR pair listing. If the variable is not in the list, then the next available index is assigned -- where next available index is numVars (from SCHR) plus 1.
This means:
* Changing the type of an existing variable will not affect its index number.
* Reordering variable definition will not affect their indices, though it will affect the ordering of the SLSD/SCVR pairs.
* Renaming a variable will result in a new index number being assigned, which means that savegames will effectively have the value reset. (Since savegames remember variable value by index.)
* Deleting a variable, compiling and then readding the variable will cause the redefined variable to have an new index number. This is because when the variable is deleted, it is removed from the SLSD/SCVR pair list, and so the compiler is not able to find it's old index number when the variable is redefined.
* Renaming a variable will likely cause othe scripts attempting to access it to lose it -- until they too are modified to use the new name and recompiled.
Note: It appears that the savegames store all numbers (despite their short, long, float designation) as doubles (64 bit floats). Refs are stored differently, but in the same space(?)
It seems that problems can arise if their is a conflict over what a given index means. This can happen if:
# a master defines a script with 4 variables
# a mod overrides the script and adds 2 more variables
# the master then is updated to add another variable
# player starts playing with master version 2, then loads mod (compiled on version 1 of master script), since there is now a conflict over what variable index 5 refers to.
This might in particular be a problem when a float is reinterpreted as a ref value. It is suspected that this conflict was the source of some CTDs when version 1.3 of OOO (built on top of unpatched Oblivion) was used with savegames using patched Oblivion.

Piecing it together for women and girls. The gender dimensions of HIV-related stigma: evidence from Bangladesh, the Dominican Republic and Ethiopia
Advocacy Materials
36 p.
This report focuses on the gender dimensions of HIV-related stigma. It aims to fill a gap and advance a more nuanced understanding and more effective advocacy on how stigma affects women and girls living with HIV more, less or differently to men and boys. This is an advocacy tool for use by relevant stakeholders - from international donors to global policy makers, national governments, programme managers, civil society and people living with HIV. It builds on current policy debates by providing concrete evidence from three diverse countries (Bangladesh, Dominican Republic and Ethiopia) that have implemented the People Living with HIV Stigma Index. The report starts by outlining the context: explaining the pieces of the HIV, gender and stigma "jigsaw" and providing a framework for analysis. (This framework is based on four, interwoven levels where the gender dimensions of HIV-related stigma are most prevalent: health, work, social settings and rights.) It then uses that framework to present case studies from the three countries - using quantitative and qualitative information to illustrate what the gender dimensions of HIV-related stigma mean in reality. It then draws conclusions about key commonalities, differences and issues across the countries. The report ends with a Call to Action to mobilize all relevant stakeholders to play their full role in responding to the gender dimensions of HIV-related stigma.

The proposed Education Bill 2003, up for debate in parliament, seeks to make primary education "free and compulsory." This enabling legislation, which will give effect to last year's decision to make education a fundamental right, is a noble goal, but its implications for contemporary Indian conditions must be understood alongside this intention.
The first question is "Who are we compelling"? The law is aimed both at state authorities to provide universal education, and also at parents and guardians to "cause the child to attend an approved school."
But what kind of parent withholds his or her child from school, and why? These parents are unlikely to be those that have written this bill or are reading this article. More likely such a parent will belong to the rural or urban poor. Why do some of these parents not send their child to school? According to the Public Report on Basic Education in India (PROBE) survey (Oxford University Press, 1999) parents in even the most backward states want their children to be educated. In rural Uttar Pradesh 92% of the parents considered it important for their girl children to be educated, the ratio rising to 100% when asked about boys. In Bihar, the figures were 88 and 99% for girls and boys respectively.
Motivation for education need not be the same as motivation for schooling; parents may be convinced of the value of education, and yet feel that the schooling system fails to provide much education.
If that's the case, what prevents parents from sending their children to school and achieving nearly universal education today? As PROBE states, "for one thing, motivation for education need not be the same as motivation for schooling: parents may be convinced of the value of education, and yet feel that the schooling system fails to provide much education". Further, the report notes that "even if parents are keen to send their children to school, they may be unable to do so for various reasons: lack of facilities, high costs of schooling, need for the child at home, and so on."
The report provides the example of students in rural Madhya Pradesh: Nandu is 10, and has been to school for four years. He can make out individual letters but cannot pronounce a single word. His elder sister, who dropped out after class 3, cannot read either. Nor can his friend Chena Lal who is in class 5. Chena Lal has confirmed what Nandu's uncle knew already: sending Nandu to school has been a waste of precious time and money. The Education Bill recognizes some of these problems, but its goal remains compulsory school attendance, rather than any measure of expected learning.
Parents face other constraints to sending their children to school too. Despite schooling being "free" parents incur additional costs, such as for textbooks, clothes or travel. Often, they may need older children for domestic chores such as looking after younger siblings while they are themselves at work, or for helping in farm work. In our large population, even a small percentage of such parents could number in the millions.
Creating a compulsory system, without addressing primary factors such as teaching standards and parental constraints will create another law that is directed at the people rather than for them. This could in turn lead to harassment from authorities, with the under-privileged sections bearing the maximum brunt. It would create further scenarios for corruption and extortion such as for falsifying school attendance records.
A further question relates to apprenticeships, where some children might learn a traditional family occupation as the source of their future livelihood, rather than attend a non-functioning school. Should the state force a child to attend a formal school, when s/he may instead be obtaining skills for gainful employment in a different way? This question is especially vital to rural students, who even after schooling often encounter a debilitating language shift for higher education and often find the urban employment system relegating them to chaprasi-hood in the organized sector. Again, the central question is: who should decide - the parents and children, or the State?
Alternative schooling is also applicable to some parents and children who are not poor. Even in affluent countries, some parents prefer not to send their children to regular schools for a variety of reasons - religious, social or family related - and prefer instead to "home-school" them. Later these students may be qualified to enter the mainstream education system by taking some standardized proficiency tests. Compulsory schooling may thus become an infringement on civil liberties, restricting parental choice over their child's upbringing and education and replacing it by the edict of a State dictating education through its system of recognized schools.
These factors must be considered before a proposal for compulsory schooling is passed into law. It may be better instead to put into place a system that creates universal opportunity rather than universal coercion. This includes raising the quality of state-run schools, working flexibly with parental constraints, including long-range career planning for joining the workforce and having clear metrics and accountability for learning, rather than simply school attendance.

Questioning and feedback Essay
Effective learning always allows room for improvement. Hence, academic feedback is an essential part of the whole teaching process. It is critical for the achievement of in-depth understanding. Feedback can either motivate or degrade a student and thus, good pedagogical procedures must be undertaken in order to generate positive effects. One positive effect of employing good pedagogical procedures when giving corrections to the students is that they will feel important.
They will realize that their instructor pays good attention to them and want them to perform well in class. They will understand that their teacher is not merely concerned on finishing a particular lesson, but focuses more on their own understanding of those lessons and pays close attention on their respective concerns such as opinions, clarifications and related experiences. Moreover, they will realize that their efforts are not wasted so they will be more focused and determined. Another good effect is that appropriate and accurate corrections allow the students to reflect on their own academic performances. They will try to look back on what they have done in class and will aim to perform better in order to achieve higher goals.

In this manner, academic feedback works as a motivator to the students. Moreover, corrections that are addressed quickly and in a matter-of-fact fashion create a healthier and friendlier student-teacher relationship. The classroom environment is warm and this allows the students to share their own perspectives.
The students will be more motivated to explore and experience because they understand that mistakes are nothing but natural part of learning and that their teacher is there to guide them along the way. When giving corrections, teachers must understand that its goal is to motivate the students and not degrade, humiliate and embarrass them. Academic and behavioral feedbacks which are inappropriate and insensitive will only generate fear to the students. They will then begin to fear committing mistakes, making their actions trivial to themselves because their goal will only be to do things perfectly without even understanding them. Furthermore, such kind of feedback humiliates and lowers the morale of the students. This will eventually affect not only their academic performances but most especially their social interactions with fellow classmates and other people.
Teachers must know that a school is an environment which greatly influences the character and personality of a student. Therefore, she must be sensitive enough to the feelings of the students while being objective at the same time. In addition, there is a possibility that in the long-run, students will no longer want to accept feedback because of their humiliating experience about it. If that happens, effective learning would not be achieved.
There can be different ways of employing appropriate and accurate feedback to a group. One of which is by recalling the objectives. In a particular lesson, the teacher sets specific and measurable objectives which are expected to be achieved by the end of the lesson.
By recalling the objectives, the teacher emphasizes the goals the students should meet. She enumerates these objectives one by one and allows the students to determine whether or not they have achieved the specific objective. This correction procedure includes the reflection of the students based on what they have done and initiates further involvement if needed. Another way is by providing a correction checklist. After a particular activity is done, the teacher will give the each group a slip of paper which contains specific actions needed to be undertaken by the students. This direct correction procedure will allow student to analyze why they still need the indicated corrections in order to meet specific objectives.
Moreover, they will try their best to respond to whatever is indicated in the checklist so that they will feel good about themselves for being able to successfully complete a given task. Allowing self-evaluation ad correction can be another way of employing academic feedback. In this process, the teacher gives a set of rubrics which will be the basis of each student for the evaluation of their respective groups. Afterwards, the students will take all possible corrective actions. With this procedure, they will be able to evaluate their group’s performance point by point and correct themselves. They will also be able to understand the importance of meeting the learning objectives for effective understanding. Fourth would be allowing group-to-group evaluation.
With a given set of criteria or rubrics, each group would evaluate the other and offer suggestions to achieve improvement. In this activity, not only will the students be able to internalize to corrections given to them by fellow students, they will also be able to experience giving feedbacks. From these, they will realize how important it is to give accurate and appropriate feedback to achieve success for a particular activity. Last would be reteaching. In this method, the teacher will identify the errors and re-teach a particular part of the lesson to correct the said errors. Although this may take time and result to adjustments, Hofmeister and Lubke (1991) believe that “it would be better to delay the new material a day so as to help initial success once it is introduced” because prerequisite skills are already mastered.
As the importance of feedback has already been identified, it is also significant to employ appropriate feedback strategies. First is giving feedback to the whole class. In this strategy, the teacher will talk to the class as a whole after it has accomplished a teacher-generated activity.
She will recall the objectives of that particular activity and then give both of her positive and negative feedbacks to the class. Finally, she will determine the overall performance of the class by giving the class a specific rating or score. According to the IELTS Teaching Resources (n.d.), feedback to the whole class is good if the mistakes are common to several students.
This strategy will also save up time while allowing the students to recognize their respective performances. For whole class feedback, IELTS emphasizes that giving corrections and eliciting them from the students are important. Moreover, corrections written on board and delivered orally should be balanced. Next is giving feedback to small groups. In this particular strategy, the teacher will give her feedbacks, both positive and negative to each group.
For this one to be effective, she needs to take note of everything a particular group has done, and then present it orally to the respective group and give her objective evaluations. Feedback to small groups is good if the instructor wants the students “to work out what the mistake” and to focus on interaction (IELTS Teaching Resources, n.d.). Last is giving feedback to individuals.
This kind of strategy will be employed after the class. The teacher will evaluate a student’s performance and give the appropriate feedback. Depending on the teacher, she may give her feedback to the student alone or may ask his or her parent or guardian to come. This is effective if there is a lot of time available to focus on each student’s concerns and if the instructor wants each of them to correct their mistakes in individual performance and homework (IELTS Teaching Resources, n.d.

The first two bands from the end indicate the first two significant figures of the resistance in ohms.
The third band indicates the decimal multiplier.
The last band stands for tolerance or possible variation in percentage about the indicated values.
Sometimes, this last band is absent and that indicates a tolerance of 20%.
For example, if the four colors are orange, blue, yellow and gold, the resistance value is 36 × 104 Ω, with a tolerance value of 5%.

Stamp Chumaks (salt-traders) it reflects the thematic directions:
An anniversary is the date on which an event took place or an institution was founded in a previous year, and may also refer to the commemoration or celebration of that event. For example, the first event is the initial occurrence or, if planned, the inaugural of the event. One year later would be the first anniversary of that event. The word was first used for Catholic feasts to commemorate saints. Most countries celebrate national anniversaries, typically called national days. These could be the date of independence of the nation or the adoption of a new constitution or form of government. The important dates in a sitting monarch's reign may also be commemorated, an event often referred to as a "Jubilee".
A coat of arms is an heraldic visual design on an escutcheon (i.e. shield), surcoat, or tabard. The coat of arms on an escutcheon forms the central element of the full heraldic achievement which in its whole consists of shield, supporters, crest, and motto. A coat of arms is traditionally unique to an individual person, family (except in the United Kingdom), state, organisation or corporation.
Mammals are any vertebrates within the class Mammalia (/məˈmeɪli.ə/ from Latin mamma "breast"), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. All female mammals nurse their young with milk, secreted from the mammary glands. Mammals include the largest animals on the planet, the great whales. The basic body type is a terrestrial quadruped, but some mammals are adapted for life at sea, in the air, in trees, underground or on two legs. The largest group of mammals, the placentals, have a placenta, which enables the feeding of the fetus during gestation. Mammals range in size from the 30–40 mm (1.2–1.6 in) bumblebee bat to the 30-meter (98 ft) blue whale. With the exception of the five species of monotreme (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The largest orders are the rodents, bats and Soricomorpha (shrews and allies). The next three biggest orders, depending on the biological classification scheme used, are the Primates (apes and monkeys), the Cetartiodactyla (whales and even-toed ungulates), and the Carnivora (cats, dogs, seals, and allies).
Transport or transportation is the movement of people, animals and goods from one location to another. Modes of transport include air, rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles and operations. Transport is important because it enables trade between people, which is essential for the development of civilizations.

Feedback Approaches
Both formative and summative assessment should be seen as a vehicle for providing opportunities for learning, therefore in designing assessment tasks consideration should be given to the opportunities which will be provided for students to obtain feedback.
Feedback is most helpfully conceptualised as an iterative process through which the learner submits work, receives verbal or written comments, and then has the opportunity to put what they have learnt into practice, ready for another cycle of feedback.
Prompts for critical thinking
• What types of feedback information will be provided and by whom?
• How will learners be given information about feedback and how they are expected to incorporate it into their activities?
• How will feedback be framed so that learners can respond to it constructively?
• How can peer feedback be designed creatively to engage learners in improving their own and others’ work and understanding?
• How will you facilitate dialogue about assessment, so that feedback is a reciprocal conversation, rather than a one-way process from tutor to student, enabling clarification of the feedback and increasing understanding?
Building students’ understanding of assessment (assessment literacy)
Assessment literacy develops student understanding of the nature, purpose, and methods of assessment, and the criteria and standards against which their work is evaluated. This enables students to develop as independent learners and to improve their performance. Regular opportunities for feedback will be an integral part of any assessment literacy strategy (see feedback strategy). Developing the ability to make a confident and accurate judgement of their own work against accepted academic standards will require practice and time. Therefore adopting a range of approaches will promote greater assessment literacy, for example, use of exemplars, marking exercises, and self- and peer- assessment. The prompts below are designed to help you create an effective assessment literacy strategy:
• Are learners familiar with the kind of assessment tasks you are using or will these be new to at least some of your learners?
• What does the learner need to be able to do or know about the assessment format (e.g. how to participate in role-plays, how to format portfolios, public speaking?
• How will learners know why they are completing the assessment?
• How can you best convey to learners what they need to do to address the assessment tasks?
• Are there adequate opportunities for learners to discuss and clarify what is expected?
• How might you use examples of past learners’ work to clarify what constitutes good work for present learners?
• Are there opportunities for learners to practice assessment tasks in class, e.g. through activities, short presentations or quizzes and/or discuss formative assessment activities which facilitates dialogue around expectations and standards?
• Have you integrated opportunities for students to engage in self- and peer-assessment which enables them to work with assessment criteria and standards in order deeper understanding?
• How can you best use marking rubrics with your learners to clarify expectations?
• How will you develop students’ understanding of academic integrity?

Introduction: Birth weight is considered to be an important predictor of health status of population. Macrosomia and low birth weight have a negative short-term and long-term impact on the health of newborn. The aim of this retrospective study was to investigate the evolution of parameters - birth weight and length of newborns at the Clinic of Gynecology and Obstetrics in Kosice-Saca.
Materials and methods: In two reported period (1986-1990 and 2014-2018) we analyzed demographic data of newborns and their mothers hospitalized in the first private hospital in Kosice-Saca. We recorded demographic data such as neonatal birth weight, birth length, sex but also the parity and maternal age.
Results: Overall, there were enrolled 12,193 newborns. In both study periods, we recorded a higher percentage of boys, which was not statistically significant. A significant statistical difference was observed when we compared birth length and birth weight while there was a significant decrease in both parameters (P ˂ 0.001). In the group of newborns under 2,500 g where we compared the two groups, we have found a higher percentage in the period 2014-2018, the difference was statistically significant (P ˂ 0.05).
Conclusion: Birth weight has a significant impact not only on postnatal adaptation and short-term complications but also the long-term health and the risk of chronic diseases and not only in childhood but also during adolescence and adulthood. In our study, we confirmed the trend of global decline in birth weight and length at our clinic. However, it is necessary to conduct additional studies, which could reveal the factors influencing this trend.
Key words: birth weight, birth length, newborn
