Opis:: A beam propagation at inhomogeneous medium is treated in parabolic approximation. For a liquid with gas bubbles a model equation which combine Khokhlov-Zabolotskaya equation with a weak dispersion was derived. Equation with new coefficients which are revised for compressible liquid is obtained. That is essential for dynamics of bubbly liquid with small volume concentrations of bubbles. A physical realistic ranges of parameters in which the derived equation is valid are specified.

Opis:: The results of the study of melting of Bi-Sn and Pb-Sn polycrystalline layered film systems with the thickness of 200-400 nm on a substrate with temperature gradient are given. Multilayer (each layer is of 10-20 nm) and bilayer films (layers are of 100-200 nm) of the same total thickness have been investigated. Broadening of the melting range in all films and lowering of melting point in multilayer samples compared to the bilayer ones have been observed. The observed phenomena are discussed within existing thermodynamic concepts in consideration of interfacial energy of contacting layers of components and energy of grain boundaries in polycrystalline films.

Opis:: The stress-strain of thin multilayered coatings covered the surface of the rail is studied near the region of side contact in turning motion. The stress-strain state is studied for various geometric and mechanical coating parameters' values. A theoretical and a finite element models are developed. Stress-strain state analysis has been made based on models developed and recommendations were given for an optimal coating parameters' selection.
