Mathematical modeling of synthesis technologies of powder materials for the space robotics
The production process is analyzed and a brief description of the main theoretical models of spark plasma sintering (SPS) is given. The experience of the use of numerical modeling by the finite element method (FEM) using specialized software for the study of SPS is examined. Goals and objectives of numerical simulation of the process are formulated. The main shortcomings and limitations of known methods of modeling are outlined.

Photoluminescence of the 15NV–-center created by implantation
We study the properties of the spin states in single diamond 15NV–-center at the ground state level anti-crossing. Our approach uses a complete set of commuting operators. We have shown that under certain conditions in 15NV–-center it is possible to obtain a 100 % transfer of polarization from the electron spin to the spin of the 15N nucleus. We believe that these conditions can be satisfied for 15NV–-centers obtained by implantation.

The problem of hereditary sin in F.M. Dostoevsky’s novel The Brothers Karamazov
The analysis of the problem of “hereditary sin” in Dostoevsky’s novel The Brothers Karamazov is considered in the light of the discussion on the theory of “hereditary sin” within modern Orthodoxy. The author examines the “threshold situations” faced by the novel’s characters and ...
