review text: Summary: A new class of spatially homogeneous Kantowski-Sachs string cosmological models with bulk viscosity in \textit{K. Nordtvedt} [``Post-Newtonian metric for a general class of scalar-tensor gravitational theories and observational consequences'', The Astrophysical Journal 161, 1059--1067 (1970; \url{doi:10.1086/150607})] general scalar-tensor theory of gravitation with the help of a special case proposed by \textit{J. Schwinger} [Particles, Sources and Fields. Addison-Wesley, Reading, Mass. (1970)] is obtained. In this paper we have presented anisotropic as well as isotropic cosmological models. Some important features of the models, thus obtained, have been discussed. These exact models are new and more general and represent not only the early stages of evolution but also the present universe.
