Query: Bulk Viscous Cosmological Models in General Relativity   A new class of exact solutions of Einstein's field equations with bulk
viscous fluid for an LRS Bianchi type-I spacetime is obtained by using
deceleration parameter as variable. The value of Hubble's constant $H_{0}$ is
found to be less than one for non-flat model and is equal to 1.5 for flat model
which are of the physical interest. Some physical and geometric properties of
the models are also discussed.
