Papers are presented on such topics as mutual diffusion between metallic plates, temperature fields in thermionic converters, asymptotic methods for solving problems of elasticity theory, traveling electromagnetic waves in a ferromagnetic half-space, and flow past an arbitrary porous shell. Also considered are the Cauchy problem for degenerate quasi-linear hyperbolic equations, diffusion from an
