Authors: Scipin L , Scipin D , Petukhova V , Monakhova Z 
Published: November 2019

Abstract
The problem of solonetzic soils fertility is still one of the most important in the country. The areas of Siberia and Ural make up about 10 million hectares. To improve chemical properties of solonetz, chemical method of amelioration is applied. It’s possible to use this method on the bore muds. Number of mud storage pits only in Khanty-Mansisk is about three thousand. On Yamal the situation is the same. As ameliorants-coagulants in the conditions of Siberia and Ural their natural reserves, wastes of mining and chemical industry can be used. The method of tubes was used for the comparative analysis of the studied ameliorants. Equal soil and bore mud samples with increasing doses of coagulants allow to assess maximal filterability of solonetz, bore mud and reveal their optimal dose. The studies have shown that choice of ameliorant-coagulant is mostly determined by the chemism of soil and bore mud salinization, and also content of exchangeable sodium in soil adsorption complex. As promising ameliorants-coagulants we should consider the wastes of chemical industry – phosphogypsum, and as raw material of mining industry – gypsum, carnallite, calcium chloride.
Ecological, biotechnological and economic aspects of wheat grain processing

Abstract
The article is devoted to the consideration of issues related with finding ways how to reduce the environmental burden in the wheat grain processing. Based on the analysis of the current state and prospects for the development of the grain processing, flour and bakery industries, the prospect of finding technological solutions for the processing of wheat grain, precluding the formation of bran as a by-product, is substantiated. It has been shown that, due to its chemical composition, wheat bran is a valuable ingredient from a biomedical point of view for inclusion in the diet of a modern person. It is noted that currently used in the baking industry for the enrichment of high-grade wheat flour with dietary fiber and bran can not be called the best from an economic point of view, since they lead to a significant increase in the cost of the final product for the consumer. The authors proposed the most rational from an environmental and nutritional points of view, the method of processing wheat grain, the technology of grain bread of high nutritional value from bioactivated wheat. Due to the process of bioactivation, the content of phytin in the grain is reduced by 75% compared with the original, that allows increasing the bioavailability of the mineral substances of bread for the human body to assimilate. Economic calculations have shown the advantage of the proposed technology of “Bioamarant” bread compared to a wheat flour product containing wheat diet bran (“Dairy-bran bread”): the cost is lower by 19.54%. When producing bread from bioactivated wheat in the amount of 22.5 tons / day, 13.4 tons of wheat should be spent. That is, the absence of the process of grinding this amount of wheat grain prevents the formation of 2.5 tons of bran per day, as well as the formation of emissions into the atmosphere in the amount of 3.2-6.5 tons (in terms of a year) of harmful substances, which will certainly allow reduce environmental stress.

Authors: Ivanchenko O , Aronova E , Balanov P , Smotraeva I 
Published: November 2019

Abstract
This study is devoted to the problem of improving the methods of pectin obtaining from apple pomace. The relevance of the study is dictated by the fact of formation of a large amount of waste when receiving apple juice. The output of apple juice at the enterprises of the processing industry is from 50 to 75%, therefore, 25-50% is waste. In our studies we used 42 KHz frequency of ultrasonic vibrations. The powers of ultrasound waves were 30 and 50W. The output of pectin depends on the sample exposure time, and with time passing this growth decreases and eventually stops, which may indicate that a certain amount of destruction has been reached at a given power. The maximum increase in the output of pectic substances is observed when the ultrasonic treatment time is 15 minutes and it is 26%. Capacity also affects pectin output. With power increasing from 30 to 50 W, the amount of pectin released increases by an average of 10%. It is shown that the use of separation at the stage of solution partitioning from pectin allows one to increase the speed of the process by a factor of two.

Published: November 2019

Abstract
Pneumatic muscle is a new type of actuator that has a number of advantages over pneumatic cylinders, such as higher power-to-weight ratio, smooth speed adjustment, and longer operating life. Pneumatic muscle-based industrial devices can be used in combustible, explosive, and contaminated environments in different industry fields. This article is dedicated to the modeling of pneumatic muscles manufactured by FESTO, a global leader in the production of this type of pneumatic actuators. The existing pneumatic muscle models have several significant drawbacks: they can only be applied to specific types of pneumatic muscles and are inappropriate for FESTO pneumatic muscles, their accuracy is low, and they contain too many adjusting factors. The model presented in this article makes it possible to obtain static characteristics with up to 10% accuracy. The aim of this study is to assess the feasibility of application of the developed expression for modeling the dynamic characteristics of pneumatic muscle and to develop a comprehensive mathematical model of pneumatic muscle for describing the processes of raising and lowering a load.

Published: November 2019

Abstract
In the life of modern society information and communication technology occupy a significant place, being an active principle of social changes. Practically all processes, one way or another, go along with technologies. The total penetration of information and communication technologies into all spheres of life initiates the transformation of established social relations and norms. Particular attention we pay to the study of social norms in virtual reality. We observe the main forms of deviant behavior in the network, and the mechanism of social control, aimed at their regulation. At the same time, we prove that the areas of regulation are quite mobile and do not have a clear framework. Although we try to define three main areas of this type: area of law regulation, area of moral regulation, unregulated field. All the presented areas describe the visible phenomena. The essence of the virtualization process, however, turns out to be undetected. But after all, society itself can set a socially acceptable framework for the functioning of information and communication technologies, which can vary depending on religion, national circumstances or level of economic development. As a result, it can be noted that in the modern world the social landscape is changing dramatically.

Published: November 2019

Abstract
The article is devoted to non-classical ergonomic of eSports. The theoretical foundations of non-classical and post-non-classical ergonomics of immersive and interactive environments are considered as applied to the activities of cybersportsmen. It is shown that the use of tools and the conceptual basis of classical ergonomics and engineering psychology are not enough to consider the self-organizing processes of mutual orientation of the gameplay participants in an artificial dynamic environment of activity. The new conceptual basis includes philosophical and natural science positions of radical and epistemological constructivism, which allows considering the recursive processes of autopoietic self-organization that take place in the subjective and communication sphere of gamers in the process of achieving a game result from a unified systemic position. The issues of professional training of gamers, the inclusion in the gaming environment, immersiveness and interactivity of artificial environments are considered. The problem of presence in the game world as criteria for the incarnation of the gamer’s “I” in the “I” of an effective game character is analyzed.

Published: November 2019

Abstract
Analysis of the separation devices’ operation and improvement of efficient gas mixture purification processes is relevant issue and is a great interest for the specialists of different industrial brunches. Modernization of internal devices in the cases of existing separators is the main goal in the field of increasing the efficiency of fine dispersed particles’ collection process. Design of a rectangular separator with a number of I-beams has been developed. Operation principle of the device is described. When the multiphase flow moves between the device elements, the centrifugal force appears, that ensures the coagulation of finely dispersed liquid drops, facilitating their uniform settling on the entire surface of I-beams. The advantage of these separators is noted. High values of centrifugal force are achieved at relatively low gas flow rates that allows to carry out the separation processes at low energy costs. Numerical study of the gas mixture flow through the rectangular separator is shown at different values of the flow rate and different diameter of particles. The results of separation efficiency are shown for different designs of I-beams. Increase in the rate leads to efficiency increase. Ranges of efficient operation of the separator have been determined. Studies showed the advisability of using the rectangular separators to purify the gases from finely dispersed particles.

Published: November 2019

Abstract
The main physical and chemical regularities for development of a flow gasifier for thermal processing of coal-water fuel (CWF) on condition of the set structure received syngas are presented in this article. Based on the calculations made on the residence time of a CWF drop in the reactor and the time of gasification reactions the gasifier was designed with vertical heating surfaces. Calculation of the main sizes of a gas generator for gas productivity on synthesis gas 500, 1000 and 1500 m3/h is carried out. The results of a constructive calculation show that in order to ensure the required residence time of a CWF particle in the volume of the gasifier it is necessary to ensure a certain length of the reactor, regardless of the gas throughput.

Abstract
A mathematical model of heating of inhomogeneous medium “TEH-sand-air” was constructed and investigated as an initial-boundary value problem for the heat equation in polar coordinate system with boundary conditions that take into account the peculiarities of thermal processes at the boundaries of the inhomogeneous medium. A solution is given to the initial-boundary problem and an algorithm is proposed for calculating the thermal characteristics of the heating process and regular temperature conditions. The study is relevant for development of a computer virtual model of the heating process of an inhomogeneous medium in order to clearly demonstrate the heating process over a short period of time, as well as to calculate the corresponding thermal characteristics based on real experimental data.
