Currently, stocks of hardwoods in the Russian Federation are severely depleted and there is a shortage of raw materials on the market. One solution to this problem is the possibility of replacing hardwoods with pressed wood obtained from softwoods. As a result of the performed study, the change in the layer-by-layer density in the thickness of blanks made of pressed wood was found. The variation of density in the thickness of the workpiece depends on the moisture content of the wood at the time of pressing. At a humidity of 15 %, the wood is more compacted in the Central part than on the surface of the workpiece. When the humidity corresponds to the saturation limit of the cell walls of 30 %, the wood on the contrary is less compacted in the Central part, as well as on the surface of the samples. It was found that with the same average density of blanks made of pressed wood, the difference between the densest and less dense parts of the workpiece averaged 7.6-10.1 %. Based on these data, it is possible to obtain pressed wood with a given density distribution over the thickness of the workpieces. The results of the experiments will be useful in obtaining pressed wood with specified quality indicators, as well as in the manufacture of various structural elements and components from pressed wood.

The growing role of the judicial community in reforming the judicial system actualizes the scientific problems of law enforcement associated with understanding the essence of the regulatory impact of the Councils of Judges of the Russian Federation as a body of the judicial community to prevent the emergence of conflicts of legal interests in judicial activity. The purpose of the research is to theoretically substantiate the essence of individual regulation of conflicts of legal interests by the Council of Judges of the Russian Federation, aimed at optimizing its activities to combat corruption. The worldview and methodological basis were the works of theoretical scholars and their methods of integrative understanding of law to substantiate the impact of the Council of Judges of the Russian Federation on judicial activity through individual regulation. The conclusion is substantiated that the activities of the Commission of the Council of Judges of the Russian Federation on Ethics, related to the drawing up of opinions on the assessment of conflicts of legal interests and other corruption risks for both acting judges and retired judges, is an individual regulation of legal relations through: interpretation of law; overcoming gaps and conflicts in the law; individuali zation of rights, etc. The content of the interpretation of law by the Commission of the Council of Judges of the Russian Federation on Ethics is: the application of certain norms of both international and national law in a specific legal relationship when assessing conflicts of legal interests among judges through a systematic interpretation of the norms of law as a system of elements, defining its role in law, identifying other norms, as well as the principles of law; interpretation of the principles and norms of law, through the legal-logical interpretation of a normative act as logically interconnected structural elements of a single, internally agreed and consistent system of principles and norms of law, when deciding on the presence of conflicts of legal interests in the activities of judges, etc. The paper substantiates that in relation to conflicts of legal interests, individualization should be aimed at determining by the Council of Judges of the Russian Federation typical situations of such conflicts for their correct assessment and development of recommendations related to the optimal behavior of judges, when circumstances arise that lead to conflicts of legal interests.

The increasing demand for zinc and a range of zinc-related metals (for example: lead; indium; tin; cadmium; and copper) in the Russian Federation cannot be satisfied by the existing production plants due to the lack of raw materials. At the same time, ferrous and non-ferrous metallurgy and the chemical industry have accumulated hundreds of millions of tons of zinc wastes (falling into the hazard categories 2 to 4), the processing of which could not only make up the raw material base, but also improve the environmental situation. In the world, over 85% of ferrous dust is recycled using the Waelz process. The Waeltz process is used for distilling separation of elements under reducing conditions. In this study, a block diagram for production of the following elements from industrial wastes is proposed: zinc, cadmium and indium in form of massive metals; zinc and indium in the form of fine powders; and clinker as a raw material for cement production. The technical and scientific details of this new process have been patented in the Russian Federation and abroad. For the first time, the following operations have been implemented with the use of large-sized Waelz kilns: vapour-oxidized Waeltz treatment of polymetallic wastes; recycling of heat from gases and solid products with generation of process fumes; and implementation of alternative flux (dolomite) and alternative fuel (petroleum coke). Keywords: Waelz process, industrial wastes, heat recycling, vapour-oxidized Waelz processing

In the current legislation of the Russian Federation, there is no concept of a land dispute, which causes difficulties in determining the competence of an arbitration court in cases in which the object of the dispute is land. The article analyzes the general legal concept of a dispute and the sectoral concept of a land dispute developed by scientists. The author identified the characteristic features of a land dispute and its structural elements. The work reveals the influence of the structural elements of the land dispute on the type of production in which the dispute will be considered. In addition, the author concludes that the correct definition of the structural elements of the land dispute enables the arbitration court to determine the appropriate persons participating in the case, the subject of proof, the relevance and admissibility of evidence, and ultimately make a lawful and wellgrounded court decision.

Research background: A series of changes towards the greater openness to the influx of foreign labour force made in recent years in the Russian Federation prompts for analysis of immigration to this country as adopted solutions in the field of the migration policy affect other regions of destination (e.g. EU). Liberalisation of access of migrants to the Russian labour market is a part of a wider problem: competition (on an international scale) for an influx of foreign labour force. In this context, it is worth examining how the crisis which affected the Russian economy influenced the scale of immigration to Russia from the main sending countries, i.e. the countries of the Commonwealth of Independent States (CIS). Purpose of the article: The aim of the article is to show the impact of the crisis which affected the Russian economy in recent years on the scale of immigration from the CIS countries to Russia. The main hypothesis is as follows: the factor explaining immigration from the CIS countries to Russia is the difference in the level of income measured by GDP per capita (PPP) between the sending state and the country of destination. Such studies have not been undertaken so far and, due to the role of factors inherent in the concept of post-imperial migration, it becomes relevant to examine whether the factors shaping migration (including the differences in the level of income) recognised in the neoclassical theory of migration are important in explaining the flows in this area. Methods: In order to check the relationship between immigration and the economic crisis in Russia, the analysis of correlation and regression was used. Findings & Value added: It has been shown that despite the decline in GDP in Russia, immigration from the CIS countries to Russia is not decreasing. Therefore, it is a dependence different from the assumptions of the neoclassical economy according to which the reduction of differences in the level of income between the sending state and the country of destination reduces the scale of international migrations. As it has been shown, the scale of migration to Russia may not be explained by the difference in the level of GDP per capita in all CIS countries and, inter alia, political factors, conflicts or naturalisation processes become more important in shaping the scale of migration to Russia.

The Murmansk region is a region with the largest enterprises of the mining complex of the Russian Federation: KF JSC “Apatit”, JSC “Kola MMC”, JSC “Olkon”, JSC” Kovdorsky GOK”, JSC” North-West Phosphorus Company”, LLC”Lovozersky GOK”. They provide the majority of the country’s demand for phosphate ores, zirconium raw materials (baddeleyite), niobium, tantalum, and rare earth metals. In addition, the mining and processing of copper-nickel, iron and chrome ores, nepheline and ceramic raw materials, facing stone and building materials is carried out. At the same time, the activities of enterprises have a very negative impact on the environment. The issues of environmental safety in the extraction and processing of minerals, storage of mining waste in the Arctic zone of the Russian Federation are of particular relevance. The definition of sustainable development in relation to the mining industry is given. The concepts of available best technologies, circular economy, and “green growth” are considered from the point of view of their contribution to sustainable development. It is shown that the sustainable development of enterprises at the present stage is impossible without improving the environmental friendliness of production. The article analyzes the legislation of the Russian Federation and the practice of its application to identify mechanisms that promote sustainable development and eliminate barriers to the implementation of this concept in the mining industry. New technological solutions have been developed for mining enterprises of the Murmansk region, aimed at reducing aero-technogenic emissions, cleaning waste (mine) water, processing tailings of enrichment as man-made deposits, which allows both to minimize man-made environmental impacts and to increase the full use of mineral raw materials. Thus, the expediency of using the principles of “green growth” for the development of economic development policies in the Arctic is justified.
