Authors: Tsukerman V A , Ivanov S V 
Published: February 2022

Abstract
The work considers the problems of the mining industry in the sphere of mining and processing waste formation and use by industrial enterprises in the Arctic Zone of the Russian Federation. The methodological basis of the work are the annual reports of enterprises, official documents and scientific publications. In result it was determined that the dynamics and efficiency of waste use by companies differ both in quantitative indicators and in the constancy of growth dynamics and the current situation is characterized by low market motivation and lack of incentives. Proposals to increase the involvement of industrial waste in economic circulation and processing was developed. It was established that it is necessary to involve industrial waste in use because of its potentially valuable consumer properties, to develop and implement low-waste technologies in cooperation with scientific organizations, and to increase the transfer of waste to other organizations as resources for the production of products.

Published: February 2022

Abstract
One of the main tasks of the state is to ensure food independence and security. Achieving food security in a particular region is possible, among other things, through the production of healthy food based on local agricultural and wild-growing raw materials. The agricultural sector of the Amur Region is characterized by large volumes of production of non-genetically modified soybeans, and wild berries grow on the territory of the region. These raw materials can be used for the production of functional foods. One of the promising objects for enriching the chemical composition and imparting the properties of a functional food product are jelly desserts. The article investigates the possibility of obtaining gelatinous soy-based desserts using wild berries, a sweetener and a structurant. The inclusion of these components in the recipe allows you to get desserts enriched with vegetable proteins, fats, carbohydrates, minerals and vitamins. Protein gelled desserts prepared according to the developed technology and recipes were highly appreciated in terms of organoleptic characteristics, they have a pleasant appearance and color, strong jelly-like consistency, light fruity aroma, moderately pronounced natural sweet taste and pleasant aftertaste.

Authors: Tsukerman V A , Ivanov S V 
Published: February 2022

Abstract
The Arctic zone of the Russian Federation (Arctic) is a unique region which ecosystems have low resilience and recovery. The exploitation of natural resources in the Arctic in particular mineral and raw materials as well as oil and gas complexes can lead to negative impact on the environment which consequences of are often irreversible. In this regard, scientifically based proposals to ensure the technosphere safety of the Russian Arctic are required in order to maintain the ecological balance during industrial exploitation which is the most important not only for the Arctic but for the entire planet. The aim of the work is to study the amounts of emissions of pollutants and greenhouse gases into the atmosphere by enterprises that directly operate in the Arctic and develop proposals to reduce the negative impact. The analysis of the largest resource companies as: PJSC NOVATEK, PJSC Severstal (Division Severstal Resources), PJSC “MMC “Norilsk Nickel” and PJSC ALROSA was carried out for the period 2015 - 2019. The analysis showed that there is no reduction in emissions at PJSC NOVATEK while at the enterprises of other companies there is a decrease associated with a reduction in production volumes or the withdrawal of certain enterprises from the company rather than the implementation of new environmental technologies in sufficient quantities. Despite the measures taken by the enterprises for environmental safety the considered indicators do not always demonstrate stable positive dynamics indicating the insufficient effectiveness of the current environmental policy and the need to develop and implement effective innovation resource-saving technologies.

Published: February 2022

Abstract
The article highlights the relationship between ensuring world food security and the pace of technological transformation of agriculture, taking into account the impact of global challenges, based on the study of theoretical approaches of leading scientists. The authors use analysis and synthesis, expert, statistical and comparative methods. The history of technological changes in agriculture are considered through its evolution from traditional food systems to Agriculture 5.0 – the post-industrial system with the use of robotics, big data and artificial intelligence systems. The authors prove that the level of agricultural development and the rate of its technological transformation are sharply differentiated by country. The cross-country analysis of indicators of food security, innovation potential, production and food net trade of the leading food-producing countries allowed us to draw two conclusions. First, developed countries that are at the top of the innovation rating and ensure national food security at a high level have negative food net trade. In the near future, these countries will not be able to have a significant impact on world food security. Secondly, countries with export-oriented agriculture are characterized by low innovation and have limited opportunities for labor productivity growth in agriculture.

Authors: Romanova G , Pesterev S , Romanov A 
Published: February 2022

Abstract
since 2010, the stevedoring companies in the Primorsky region have been actively increasing the volumes of coal handling due to growing demand for coal production (in 2.5 times) in the countries of the Asia-Pacific region.
At ¼ 2020, in the context of the stagnation of the global economy, the demand for coal remained stable in the countries of the Asia-Pacific region. Thus, in order to maintain the positions of the Russian Federation in the coal markets of the Asia-Pacific region countries, it is necessary to have due understanding of the handling capacities efficiency, the quality of coal processing services and the environmental impact in the seaports of the Primorsky region. Despite the fact that the closed coal handling technology at the specialized coal terminal used by JSC «Vostochny Port» is considered the most effective, the most local stevedoring companies use non-specialized coal handling technology by clamshells.

Published: February 2022

Abstract
The organization of the city’s passenger transport route system is the most important task of transport planning. Public transport stops in places with high demand for transportation are hubs of passenger traffic and are used jointly by different routes. This leads to queues of vehicles and causes delays in the movement of buses and trolleybuses. Reduce vehicles queues is achieved when the stops are distributed by dividing them into several landing pads. The purpose of the article is to develop recommendations to rationalize the location of urban transport stops to improve the quality of passenger service and ensure transport mobility. Methods are used in the preparation of the article: mathematical modeling, queue theory, and the results of transport research. Recommendations for transport planning have been developed: a) distribute stops into multiple parts proposed using a queue theory model, b) some models for the rational placement of landing pads at a combined stop are proposed.

Published: February 2022

Abstract
The Far Eastern Federal District (FEFD) of the Russian Federation (RF) includes 11 constituent entities with a total area of 555.3 million hectares, which is 48.5% of all forest lands in the country. Stock of wood forest plantations in the Far Eastern Federal District are 31% of the total stock of the Russian Federation, and ripe and over maturity stands prevail here. Most of the forests of the Far Eastern Federal District are boreal forests, which are known to be the regulator of the planet’s climate. The process of intensive development of natural forests in this area can lead to the release of large amounts of carbon. The unique biogeography of the region has led to a combination of unique species of flora and fauna in a single ecosystem, and, unfortunately, most of the commercial forests are concentrated in the same area. Exhausting forest management practices reduce the many interrelated protective and ecological functions of forests of local, regional and global importance. The implementation of the state policy in the field of forestry in this area is under the jurisdiction of the Department of Forestry for the Far Eastern Federal District. The current state of forestry and plans for its management are reflected in the reports of the official statistics of the department. First of all, at the state level, it is recognized that there are no relevant forest inventory materials on a part of the territory. The indicator of the availability of a stock of seeds for reforestation purposes has been fulfilled by 51.5% of the plan; the shortage of seeds of small-coniferous species is of concern. Extinguishing forest fires takes place in a controlled area, here the burning rate continues to remain last year, and the area covered by the fires increases in area. Forest fires are not extinguished in uncontrolled areas. An important problem in the region is crimes committed in the field of violations of forest legislation, namely, illegal logging of forest plantations is of an organizational nature. With all the natural uniqueness of the territory under consideration, economic activity here is fraught with a number of difficulties, which it is not possible for the executive authorities to solve on their own. Special attention should be paid to forestry in the Far Eastern Federal District.
Improving the Energy Efficiency of a Gas Compression System at a Compressor Station

Published: February 2022

Abstract
For natural gas pumping via main gas line gas compressor units are used. During the gas compressor units’ operation, there are natural gas consumption as a fuel and for technological needs. To prevent the escape of gas from the internal cavity of the centrifugal compressor N-370-18-1 into machine room, the design considers a hydraulic seal “oil-gas”. The feature of centrifugal compressor with hydraulic seal “oil-gas” is the discharge of gas from the degassing chamber through a candle into the atmosphere. Rational use of wasted gas make it possible to gain a benefit by saving raw and reducing environmental charges. The gas discharged into the atmosphere is proposed to be used in the fuel gas system of the unit. This requires to bring gas parameters in particular pressure and temperature, to the required ones. The kinetic energy of the low-pressure (passive) gas directed from the gas separator to the candle can be increased by direct contact (mixing) with the high-pressure (active gas) flow in the gas-jet ejector. The complexity of the mathematical description of all processes occurring in ejectors with a three-dimensional flow, and the high cost of conducting experiments with gases other than air, make it cost-effective to use CFD (Computational fluid dynamics) modeling methods to study the processes of gas flow in ejectors. The article presents the gas flow modeling results of the gas flow in an ejector by the ANSYS Fluent software package.
