The article is devoted to studying adsorption of enzymes,
antioxidants contained in horseradish root on
starch to create enterosorbent with anti-oxidant properties.
For this goal, we have studied adsorption isotherm
calculated constants, thermodynamic parameters
(change of enthalpy, entropy, and isobaric-isothermal
potential); sorption kinetics of enzyme-antioxidants on
starch and calculate the main characteristics. The
method of producing of enterosorbent - antioxidant on
based starches has been developed based on the experimental
data. The ready sorbent is a white powder having
no taste and smell. Insoluble in biological fluids
and water. It is the solid component. The enterosorbent
can be used to protect the gastrointestinal tract of humans
and animals against a wide variety of oxidants
and peroxide. The results of this work will form the
basis for the study of the antioxidant properties of the
resulting enterosorbent

The problem of environmental protection from the contamination by toxic products, contained in the exhaust gases, is one of the most topical in the modern world.
Nitrogen oxides and soot particles are the most toxic.
Getting into the environment and the human body, they cause heavy chronic disease and significantly impair the quality of animal and plant products. The developed gas purification system SCR, the technology of plasma purification of exhaust gases have not found wide practical applications because of their high value.
The study of papers dedicated to reducing exhaust gas toxicity shows that the use of combined means of purification, which usually include mechanical, thermal and catalytic methods of purification, is the most effective. Our work deals with the issue of purifying the diesel engine exhaust from fine particulate matter resulting in the combustion of fuel and oil motor partly.
The article notes that the carbon is not magnetic, so the use of a magnetic field acting as an agent for the purification of exhaust gas from the carbon soot particles is impossible. The purification in a centrifugal field requires the creation of structurally complex centrifuges, so it is ineffective. We consider the possibility of purifying the exhaust gases from the soot particles in the electrostatic field. The device presents the collecting electrode, which is shaped as a cylinder, and an axial central electrode, which is mounted on an insulated spacer within the cylindrical body. The study deals with the physical and mathematical simulation of processes occurring in the proposed device of the purification of exhaust gases. The equality of the Coulomb force and the Stoks force determines the magnitude of the electrostatic field strength that is necessary for the purification of exhaust gas from the soot particles. We have identified the desired length of the collecting electrode
In the article, we have considered indicators for
assessing import dependency by key
characteristics of industrial production
(technology, raw materials, equipment). The work
shows necessity of the transition from
determining the level of import dependence for
individual characteristics to determine its overall
(integrated) assessment. It presents the criteria of
evaluation of technical, technological, raw
material import dependence of production. We
have developed a model of calculation of the
generalized indicators of evaluation of level of
import dependency of production. The proposed
Toolkit allows using an expert way to assess the
level of import dependence of production of
various types of products. In this comprehensive
assessment, it takes into account the dependence
of the acquired import of components, raw
materials and borrowed technologies, and the
extent of use of imported equipment. The use of
indicators characterizing the degree of
dependence of production on foreign technology
and equipment is very important in the conditions
of modernization and technical re-equipment of
production
The state of any economic system depends on the values of its parameters, both in the current period and at previous times. Therefore, in the process of optimization of production management, it is necessary to take into account this feature of the development of the systems under consideration. The most important task of economic research is the establishment of an equilibrium price. The most suitable hysteresis converters for solving this problem, the formal description of which is based on their operator interpretation. However, at present, when analyzing the functions of supply and demand, a cobweb-like model and its analogues are used, as a rule. This article discusses the unresolved problem of optimizing production under conditions of hysteresis pricing and competition. Taking into account that their mathematical modeling is the main method of analyzing economic systems with hysteresis properties, different pricing models (discrete and continuous) are considered in the article, as well as economic and mathematical tools for optimizing production activity under hysteresis pricing conditions. The developed models can be used to increase the adequacy of the formal mathematical description of the corresponding systems, which is the basis for more accurate forecasts of their development. In the conditions of hysteresis pricing, production optimization algorithms will allow to create optimal (in terms of achieving maximum profit) price and production strategies for the development of economic systems
