TL;DR: In this article, the selfconsistent relativistic linearized-augmented-plane-wave method is applied to local density calculation of electronic structure of TmS. The influence of spin-orbital interaction is shown for different symmetry states of electrons.
Abstract: The self-consistent relativistic linearized-augmented-plane-wave method is applied to local-density calculation of electronic structure of TmS. It is found, that thulium monosulphide is a metal with a trivalent state of thulium. The influence of spin—orbital interaction is shown for different symmetry states of electrons. Calculated densities of states are used for the estimation of the electron—phonon coupling constant. And in conclusion it is shown that TmS is a high temperature Kondo-like system.

TL;DR: In this paper, the problem of crack propagation through an elastic material, containing many arbitrary located microcracks, is examined, and the problem is reduced to the system of singular integral equations and its solution is obtained by using the method of a small parameter.
Abstract: The problem of crack propagation through an elastic material, containing many arbitrary located microcracks, is examined. Mathematically, the problem is reduced to the system of singular integral equations and its solution is obtained by using the method of a small parameter. The change of stress intensity factor and the initial propagation direction of a macrocrack is obtained for different orientations of microcracks.

TL;DR: The pK's of short-lived aminic free radicals from 1,2-dihydro- and 1, 2,3,4-tetrahydroquinolines were determined as mentioned in this paper.
Abstract: The pK's of short-lived aminic free radicals from 1,2-dihydro- and 1,2,3,4-tetrahydroquinolines were determined. It was shown that the free radicals are stronger bases than the starting amines.

TL;DR: It was shown that γ -aminobutyric acid (GABA) is the precursor in the formation of aglycone IS-glucoside, and appears to be the main utilisation pathway of this amino-acid.
TL;DR: In this paper, the conditions of applicability of the dipole approximation in interactions with a laser field in scattering problems are investigated, and the results obtained are compared with the well-known Bunkin and Federov formula for induced multiphoton bremsstrahlung.
Abstract: In the first nonvanishing order of perturbation theory for the interaction with electromagnetic radiation, accurate expressions are obtained for the cross sections of two-photon processes in scattering on aδ potential. The conditions of applicability of the dipole approximation in interactions with a laser field in scattering problems are investigated. The results obtained are compared with the well-known Bunkin and Federov formula for induced multiphoton bremsstrahlung.
