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. 1. Suárez M., Fernández A., Menéndez J.

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. 1. Jelezko F., Gaebel T., Popa I. et al. Observation...

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 ...

This article studies the effect of an extern heavy atom (KI salt) on the effi-ciency of nonradiative spin-forbidden singlet-triplet (S-T) transfer of elec-tronic energy between the rhodamine 6G (donor) and acriflavine (acceptor) dye molecules in polyvinyl alcohol films. The delayed fluorescence intensity enhancement and an increase in the lifetime of the acceptor triplet states in the presence of KI have been established. The constant rates of deactivation of the singlet and triplet states of dye...

Kant’s turn to the subject has changed the epistemological conditions for theology. Four intellectual backgrounds of objections are examined: an Aristotelian and Thomistic teleological order of nature (1); Augustinianism based on original sin in which human agency is completely attributed to God’s grace (2); a Hegelian critique of the deontological conception of an “unconditional ought” which also puts Kant’s postulate of the existence of God into question (3); the combination ...

We consider a new way of solving the problem of the sinusoidal wave on the surface of a homogeneous perfect fluid. Its feature is used instead of the potential speed of the original characteristics of wave motion: horizontal and vertical components of the velocity and pressure. It is noted that it will generalize the problem under consideration in the event of a multi-layer liquid. The results, including the dispersion relation, fully consistent with the known. Specially considered long-wave approximation...

A detailed analysis of sinusoidal waves in two-layer liquid is made. The dispersion relations for short and long waves are studied. The success was helped significantly by a technique created by us. 1. Сретенский Л. Н. Теория волновых движений идеальной жидкости. М., 1977. 2. Каменкович В. М.

The author analyses the works of singer songwriters, i. e. lyrics of bard songs and rock poetry, from the point of view of their plot and their place in the typology of texts. The author identifies a discrepancy between the principles of building the plot of songs and the methods of creating the poetic model of the world in the central and peripheral areas of this type of songs. This internal asymmetry of the analysed context is associated with the borderline position of the songs in literature....
