Description
In the dairy industry, the segment of yoghurts and yoghurt drinks is one of the most dynamically developing. Competition contributes to the production of high quality products. The transition to market relations encourages producers to use new prescription ingredients in the production of various yoghurts. In addition, it is essential to improve the existing ones and create qualitatively new technologies of products with a directed change in the chemical composition. Sour-milk drinks not only satisfy the physiological needs of the body, but also have a preventive and therapeutic purpose. Utilization of these products contributes to the prevention of numerous diseases, as well as life prolongation and increase of working capacity. The dietary properties of sour-milk drinks are determined by the presence of “live” beneficial microflora and persist for a long time, as long as this microflora remains viable and pure. The article contains data distinguishing the effects of the use of commercial fermentation starters EKOKOM Laktina, TM GoodFood, Kaprina on the qualitative characteristics of dairy clots. The article specifies the influence of fermentation starters and vegetable fillers on the organoleptic parameters of the final sour-milk product. The authors of the article further present data describing the organoleptic and physicochemical quality profile of yoghurt enriched with vegetable fillers, obtained by introducing commercial fermentation starters of various manufacturing companies

INNOVATIVE FATTY PRODUCTION TECHNOLOGIES IN THE HUMAN HEALTH CARE
DescriptionEnsuring 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
DescriptionThis 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
DescriptionThe 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
