INNOVATIVE FATTY PRODUCTION TECHNOLOGIES IN THE HUMAN HEALTH CARE
Description
Ensuring food safety for a long time has a global character. The results of world scientific studies confirm the negative effect of trans-isomers of unsaturated fatty acids on the human body, convincingly proving that their consumption increases the risk of various diseases, including cardiovascular diseases. Taking care of public health, many European countries at the legislative level strictly regulate the content of trans-isomers of unsaturated fatty acids, obliging manufacturers to also issue information on the quantitative content of TIUFA on packaging. Such measures can reduce morbidity and mortality, but require the introduction of progressive technological processes. The work analyzes numerous literature sources and generalizes the material on existing types of technological modifications of fats - transesterification and fractionation, which allow obtaining specialized fats without trans-isomers or with a low content of trans-isomers of fatty acids

IMPROVEMENT OF A MULTILEVEL SYSTEM OF TRANSPORT LINKS OF FOREST ENTERPRISES AT THE REGIONAL LEVEL
Description
This article considers the structure of the regional transport system of the forest complex, in which each mode of transport is characterized by a certain structure, technology of functioning and means. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. Analytical dependence expressing the formal relationship between the parameters of various modes of transport is presented, the objective function of the organizational structure of the regional transport system management is presented, reflecting the efficiency of the entire transport system as a whole. The formulation of the problem is considered from the standpoint of game theory, in which there are four players with disparate interests: the organizational structure of the regional transport system and the three transport subsystems, each of the participants has its own control vector that belongs to the given set. We consider the case of full awareness, in which the hierarchical structure and all the objective functions of the system are known to the participants. The resulting statement of the problem is modeled by the game of four persons with conflicting interests. The game is viewed from the perspective of transport subsystems. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. An algorithm for solving the problem is given

SCENARIO APPROACH TO PROJECT MANAGEMENT
Description
The study was carried out with the financial support of the Russian Foundation for Basic Research, within the framework of the RFBR research project 17-02- 00475a "Application of metaheuristic algorithms to solving direct and inverse problems of optimizing control of spatially distributed complexes". The article considers the task of scenario approach to project management in case of abnormal progress of its implementation. Various contingencies have been analyzed in the course of project implementation. A model of the scenario approach for project management using the training principle with reinforcement is proposed

Description
In this article, on the basis of phenomenological consideration of kinetic processes in semiconductors volume, we have conducted an analysis, in order to estimate the drift and diffusion components of the output current for hot carriers in the total output of the conductivity structure of the chip. The result revealed amplitude and frequency characteristics of this component of the conductivity, illustrating a greater amount of its modulus and phase inversion near the field-strength values of Ghan effect. This can be used for designing oscillators of millimeter range of wavelengths. It is shown that the nonlinear diffusion component along with the drift is important for the output conductance of the test specimen

MODERN TECHNICAL EQUIPMENT FOR WORK IN GARDENS
Description
Gardening is one of the high-value and highly profitable branches of agriculture. However, the level of fruit production in Russia still lags far behind the needs of the population: 20-25 kg of fruits and berries per year are grown per capita, which is a quarter of the minimum consumption rate. Currently, domestic gardening has a low efficiency due to non-compliance with the criteria of world production of fruits. The production of gardens is not competitive enough and does not meet the requirements of the highest quality categories of domestic standards. To increase fruit production, it is necessary to increase the level of intensification of fruit growing using the most valuable varieties and progressive technologies of cultivation. In this article, we consider devices for soil content in orchards, as well as for pruning trees - the main agrotechnical techniques in the technology of growing pomegranate crops that promote the production of stable, optimal harvests of fruit crops. The universal device of fruits is also covered, which makes it possible to reduce labor costs during the laying, care and harvesting of the fruit garden. The wide development of intensive technologies for growing fruits adapted to specific climatic conditions and ensuring a high level of competitiveness and profitability of production is one of the necessary conditions for the further development of gardening in Russia
