Dedicated to the 120th Birth Anniversary of Academician Nikoloz Muskhelishvili

This book is dedicated to the 120th birth anniversary of the famous Georgian Academician Nikoloz Muskhelishvili. Works of academician N. Muskhelishvili had a great impact in the further development of the elasticity theory and deferential and integral equations of mathematical-physics. Works of N. Muskhelishvili represents a basis of the numerous scientific researches in number of fields, which are used in order to solve technical problems. In the represented book, the following problems are considered: non-classical mathematical models describing pollution transfer and diffusion of various mixtures in the water streams; a non-stationary magneto hydrodynamic flow of conducting fluid between two infinite rotating porous discs lying from each other at a distance-h and the problem of wave propagation in an orthotropic half-plane.
