Recently, optimization has become an important aspect of educational process management. The goal of the optimization process is usually reduced to reducing the total amount of the pedagogical load of the university, as well as to the formation of an optimal schedule of training sessions with the existing classroom fund. This article discusses the main aspects of the ...

The durability of the targets and entrance window foils of the Dubna gas-filled recoil separator working at high intensive heavy ion beams was considered. The temperature, as a factor determining their durability, was calculated as a function of time in the conditions of their pulsed heating by heavy ion beam, followed by radiative cooling by radiation emitted from their ...

We study a class of shear-free, homogeneous but anisotropic cosmological models with imperfect matter sources in the context of f (R) gravity. We show that the anisotropic stresses are related to the electric part of the Weyl tensor in such a way that they balance each other. We also show that within the class of orthogonal f (R) models, small perturbations of shear are damped, ...

This paper presents a ROOT based program that allows processing the data from experiments on the ROT-asymmetry in the angular distribution of fission products and present the results of the experiment in a convenient and visual form. The program can work with huge data sets and detect very subtle effects. The algorithm used by the program is given in this work. The overall ...

The paper is devoted to the study of radiation-induced damage kinetics in beryllium oxide ceramics under irradiation with low-energy helium ions with fluences of 1015–1018 ion/cm2 . It was revealed that at irradiation fluences above 1017 ion/cm2 , a decrease in radiation-induced damage formation and accumulation rate is observed, which indicates the saturation effect. At ...

Excavation of pits, trenches for foundations of civil buildings and industrial structures in saturated clayey soils often leads to soil structural change and great decrease in the soil strength and deformation characteristics. In some cases, an artificial sand base is used as a method for construction on saturated clayey soils. However, technology violations and unsuitable ...

In this article we derive the post-Newtonian limit of a class of teleparallel theories of gravity, where the action is a free function L(T,X,Y,ϕ) of the Torsion scalar T and scalar quantities X and Y built from the dynamical scalar field ϕ. We restrict the analysis to a massless scalar field in order to use the parameterized post-Newtonian formalism without modifications, such ...
