Query: Transverse Shear Viscosity to Entropy Density for the General
  Anisotropic Black Brane in Horava-Lifshitz Gravity   In this paper we calculate the ratio of transverse shear viscosity to entropy
density for the general anisotropic black brane in Horava-Lifshitz gravity.
There is a well-known conjecture that states this ratio should be larger than
$\frac{1}{4\pi}$. The ratio of shear viscosity to entropy density is
proportional to the inverse square coupling of quantum thermal field
theory,$\frac{\eta }{s} \sim \frac{1}{\lambda^2 }$. Especially in QFT with
gravity dual the stronger coupling means the shear viscosity per entropy
density gets closer to the lower bound of $\frac{1}{4\pi}$. The KSS bound
preserves in the anisotropic scaling model.
