The paper defines a new class of algebras, the theory of which is a special case of Jonsson theories. This class applies to both varieties and Jonsson theories. The main results of this article are the following two results. ...

The aim of this work was to study virucidal activity against SARS-CoV-2 of several anionic disinfectants, which are antiseptics recommended by the U.S. Environmental Protection Agency (EPA), and to prepare their complexes ...

One of the main priorities in the modern thermal power engineering development is the problem of energy saving due to the economical use of fuel and energy reserves. Increasing energy consumption with a simultaneous ...

In this paper we consider a boundary value problem for a loaded fractional diffusion equation. The loaded term has the form of the Riemann-Liouville fractional derivative or integral. The BVP is considered in the open right ...

The thermal properties of a copolymer based on polyethylene glycol fumarate with methacrylic acid in a ni-trogen atmosphere were studied in this paper. Four various heating rates and two types of a polyester resin composition ...

The optimal conditions of catalytic hydrogenation of oil sludge (Atasu-Alashankou) and the change in the kinematic viscosity of the fraction to 350℃ from the studied factors using the method of probabilistic-deterministic ...

The possibility of using the polymeric matrix obtained as a result of “cold” polymerization of polypropylene glycol fumarate (p-PGF) with methacrylic acid (MAA) as a polymeric base for obtaining new adhesives of domestic ...

This study examines the main factors influencing the formation of labor re-sources, which are interconnected with demographic changes that affect labor resources and, as a result, economic growth. This, of course, depends ...

The quantum chemical modeling and full geometry optimization of sisomicin and gentamicin were carried out by the correlation functional B3LYP using augmented with polarization functions for heavy atoms 6- 311G(d) and ...

The study of issues of increasing the efficiency and improving the man-agement activities of rural and local self-government seems to be a fairly relevant topic, the study of which will allow us to draw a number of ...
