Abstract: Multidimensional integral equation of the first kind with the hyperbolic sine function in the kernel over pyramidal domain is studied. Solution of this equation in closed form is established, and necessary and sufficient conditions for its solvability in the space of summable functions are given.

Abstract: The actual problem of oil oxidizability after hydrogenation and cleaning processes is considered. The separation capacity of various adsorbents is analyzed. The group composition of oils and its effect on stability are analyzed. The main theories of oxidizability, mechanisms and causes are also considered. The thermal stability of the dewaxed residual product of vacuum gas oil hydrocracking after purification and with the introduction of an inhibitor was analyzed.

Abstract: The issues of using digital processing of surface images during microhardness tests to determine the geometric dimensions of prints and deformation zones are considered. An image processing algorithm has been built and a processing program has been implemented. The simulation results can be used when testing polymer films for microhardness to determine the strength characteristics: microhardness, crack resistance, specific energy of adhesion.
