The paper presents the results of the analysis of foreign and Russian experience in the field of research and development of new methods for the accelerated determination of frost resistance of concrete, as well as a description of the experimental method for determining frost resistance by exposing the tested samples to extremely low temperatures. The development of the building materials market, the improvement of construction and installation work technologies require the use of modern high-tech technologies and means, including in the implementation of construction control at unique construction facilities. Currently used regulatory documents of the Russian Federation and standards of foreign countries imply large time costs and high labor intensity. Foreign and domestic scientific research describes other methods of testing using expensive equipment, a large amount of mathematical calculations and mathematical modeling. Reducing the time interval for testing will slightly change. The developed experimental method takes into account the requirements of the regulatory documentation in force on the territory of the Russian Federation, and implies cyclic freezing of samples saturated in a 5% aqueous solution of sodium chloride at extremely low temperatures achieved by using liquid nitrogen. Based on the results of parallel tests in accordance with the requirements of regulatory documents and in accordance with the developed experimental method, a positive convergence of the results was obtained. A significant decrease in the time of testing to determine the frost resistance of concrete was recorded, which allows concluding that it is advisable to use this experimental method, especially if it is necessary to quickly control the quality of concrete at unique construction facilities.

The article is meant to analyze current problems and prospects for the development of effective tax policy as part of digital transformation of Russian economy. Introduction of a digital tax and the consequences of the digital tax reforms in the EU, the USA and OECD countries are highlighted. The necessity of qualitative transformation of the tax system of the Russian Federation in response to modern challenges is substantiated, taking into account the changes of the Tax Code of the Russian Federation adopted at the end of July 2020. The authors suggested their own concept of a digital tax and the prospects for its adoption in Russia, and consider it inappropriate to impose taxes on Internet users who do not use the Internet for business. Today, the main focus should be made on creating and testing effective technologies that allow on-line monitoring the tax basis of digital economy entities, taking into account the cross-border movement or use of digital products (goods and services). In addition, it would be extremely important to provide for a potential tax exemption for part of the profits of international ICT companies that are received on the territory of the Russian Federation and reinvested in joint with Russian companies projects in the high-tech for civil purposes area.

Степень технологической и технической зависимости отечественных производителей овощных культур от зарубежных производителей с.-х. техники, а также их техническая оснащенность специализированными машинами объясняется высокими затратами на производство овощей, особенно на уборку, что при общем дефиците ручного труда приводит к сокращению площадей, нарушению технологии выращивания и соответственно снижению урожайности. Цель исследований – определить современное состояние технологического и технического обеспечения производства овощных культур в Российской Федерации. Для достижения поставленной цели использовали методологию системного анализа и синтеза, математической статистики, численные методы решения аналитических зависимостей. Статистические исследования современного состояния технического обеспечения производства овощей в России могут служить основой для построения модели и разработки концептуальных принципов модернизации технологического и технического обеспечения работ в овощеводстве. Определена потребность товаропроизводителей в современных высокотехнологичных комплексах машин для производства овощных культур. Проведенные статистические исследования позволили оценить современное состояние с.-х. машиностроения по выпуску необходимого для товаропроизводителей количества машин. Повышение объемов производства овощной продукции неразрывно коррелирует с уровнем технического обеспечения отрасли овощеводства в целом, что подтверждает уровень локализации с.-х. машиностроения РФ, а также Беларуси и Казахстана, где с.-х. машиностроение представлено широкой номенклатурой предприятий, выпускающих комплексы машин от предпосадочной обработки почвы до послеуборочной обработки товарной продукции. Для возрождения с.-х. машиностроения и развития рынка средств механизации аграрного производства определены основные механизмы обновления парка сельхозтехники – преимущественно привлечением кредитных ресурсов коммерческих банков и лизинговых компаний. Кроме того, интенсивность ведения сельского хозяйства в современных условиях производства невозможна без высокого уровня насыщения машинно-технологических комплексов средствами интеллектуализации. Получать качественную конкурентоспособную продукцию можно только при использовании современных высокопроизводительных машин, обеспечивающих совмещение технологических операций, в конструкциях которых заложены системы автоматизированного управления технологическими процессами, учета почвенного плодородия, обеспечения экологической чистоты агроландшафтов. The degree of technological and technical dependence of domestic producers of vegetable crops on foreign producers of agricultural machinery, as well as their technical equipment with specialized machines, is explained by the high costs of vegetable production, especially for harvesting, which, with a general shortage of manual labor, leads to a reduction in area, disruption of cultivation technology and, accordingly, a decrease in yield. The purpose of the research is to determine the current state of technological and technical support for the production of vegetable crops in the Russian Federation. To achieve this purpose, we used the methodology of system analysis and synthesis, mathematical statistics, numerical methods for solving analytical dependencies. Statistical studies of the current state of technical support for vegetable production in Russia can serve as a basis for building a model and developing conceptual principles for modernizing technological and technical support for work in vegetable growing. The need of commodity producers for modern high-tech complexes of machines for the production of vegetable crops is determined. The conducted statistical studies made it possible to assess the current state of agricultural engineering for the production of the number of machines necessary for commodity producers. The increase in the production of vegetable products is inextricably correlated with the level of technical support for the vegetable growing industry as a whole, which confirms the level of localization of agricultural machinery in the Russian Federation, as well as in Belarus and Kazakhstan, where agricultural machinery is represented by a wide range of enterprises that produce complexes of machines from pre-planting tillage to post-harvest processing of commercial products. For the revival of agricultural machinery and the development of the market of agricultural production mechanization tools, the main mechanisms for updating the agricultural machinery fleet are determined-mainly by attracting credit resources from commercial banks and leasing companies. In addition, the intensity of agriculture in modern production conditions is impossible without a high level of saturation of machine-technological complexes with means of intellectualization. It is possible to obtain high-quality competitive products only with the use of modern high-performance machines that ensure the combination of technological operations, in the designs of which there are systems for automated control of technological processes, accounting for soil fertility, ensuring environmental cleanliness of agricultural landscapes. Key words: vegetable growing, vegetable seeders, transplanters, vegetable harvesting equipment.

Abstract According to the US Energy Agency (EIA), Russia is the world leader in terms of the volume of technically recoverable "tight oil" resources (U.S. Department of Energy, 2013). To convert them into commercial production, it is necessary to create cost-effective development technologies. For this purpose, a strategy has been adopted, which is implemented at the state level and one of the key elements of which is the development of the high-tech service market. In 2017, the Minister of Energy of the Russian Federation, in accordance with a government executive order (Government Executive Order of the Russian Federation, 2014), awarded the Gazprom Neft project on the creation of a complex of domestic technologies and high-tech equipment for developing the Bazhenov formation with the national status. It is implemented in several directions and covers a wide range of technologies required for the horizontal wells drilling and stimulating flows from them using multi-stage hydraulic fracturing (MS HF) methods. Within the framework of the technological experiment implemented at the Palyanovskaya area at the Krasnoleninskoye field by the Industrial Integration Center "Gazpromneft - Technological Partnerships" (a subsidiary of Gazprom Neft), from 2015 to 2020, 29 high-tech wells with different lengths of horizontal wellbore were constructed, and multistage hydraulic fracturing operations were performed with various designs. Upon results of 2020, it became possible to increase annual oil production from the Bazhenov formation by 78 % in comparison with up to 100,000 tons in 2019. The advancing of development technologies allowed the enterprise to decrease for more than twice the cost of the Bazhenov oil production from 30 thousand rubles per ton (69$/bbl) at the start of the project in 2015 to 13 thousand rubles (24$/bbl) in 2020. A significant contribution to the increase in production in 2020 was made by horizontal wells, where MS HF operations were carried out using an experimental process fluid, which is based on the modified Si Bioxan biopolymer. This article is devoted to the background of this experiment and the analysis of its results.

The relevance of the publication topic is argued by the need for an in-depth study of the globalization process, which is global financial, political and cultural integration, unification, the global division of labour, the planetary migration of capital, human and productive resources, standardization of legislation, and interference of cultures of the world community. The theoretical and practical goals of the publication are to study causal algorithms for the formation of a negative scientific and production balance of the Russian Federation and an increase in disproportions between the import and export of high-tech products, as well as a comparative description of global development as a symbiosis of contradictory trends in the subordination of the world economy to the interests of transnational capital. The theoretical and methodological basis of the publication was the scientific works of domestic and foreign scientists studying the globalization of the industrial economy due to the intensification of international scientific and technological competition and the expansion of the innovation market, deepening of specialization and division of labour, and the increase in the risks of producing high-tech products at the national and world levels. Scientific novelty lies in the authors’ interpretation of such socio-economic advantages of globalization as economies of scale, stimulation of labour productivity, rationalization of production at the interstate level and the spread of innovative technologies, cost reduction, price regression, achieving sustainable growth in the well-being of society, on the basis of which the development is confirmed global industrial economy on a research basis characterized by such attributes interdependence, asymmetry, regionalization and diversification, regression efficiency, inclusiveness, resource and raw material demarcation, a high degree of uncertainty and of the economic risk. The practical significance of the results obtained is determined by an in-depth analysis of the American (based on differentiation of labor and specialization of personnel, demarcation of labor duties, concentration of scientific and production efforts on a purely economic result) and Eurasian (characterized by mobility and compactness of production processes, saving transaction costs, adaptability to market conditions and availability of labour-tolerant staff) strategies for innovative development of industrial economics. Based on a critical rethinking of the American and Eurasian strategies, proposals and recommendations are formulated on the formation of the scientific and technical policy of the Russian Federation

Objective. To analyze legislation regulating medical care for children with rheumatic diseases in the Russian Federation. Materials and methods. We analyzed regulatory documents of the Ministry of Health of Russia, including the rules of medical care for children with rheumatic diseases, the resolution regulating the distribution of medicines at a discount or for free, and regional legal acts regulating routing of children with rheumatic diseases. Results. The legislation regulating medical care for children with rheumatic diseases is imperfect and needs to be updated. We identified shortcomings in the system regulating preferential provision of certain groups of patients with medicines. The results of our analysis can be used as a rationale for changes and amendments to existing regulatory legal acts and for the development of new regulatory documents. Conclusion. This analysis of legal documents allows us to suggest amendments to the existing legal framework in order to reduce tensions (including legal tensions) associated with distribution of preferential medicines, reconsider establishment of disability in patients with juvenile idiopathic arthritis, expand opportunities to prescribe biologicals for non-disabled patients with systemic scleroderma, juvenile dermatomyositis, and systemic vasculitis in regions. We justified detailed description of regional legal documents regulating distribution of preferential medicines among patients with rheumatic diseases. Key words: rheumatic diseases in children, regulatory framework, health care organization, drug provision

The features of the effect of wind on a prismatic-type building with different methods of determining the coefficient of wind pressure along the height are considered. The study was carried out on the basis of studying the main provisions of regulatory documents governing design and development activities in the Russian Federation, as well as current publications of domestic and foreign scientists, corresponding to research in this area. The research method is structural and analytical analysis using the correlation dependences of the factors under study. Analytical dependencies for determining the wind forces for various methods of assigning the wind load coefficient along the height of the building and their graphic interpretation are given. The work is based on the provisions of domestic building codes and relevant information contained in other domestic and foreign sources. For prismatic buildings with a height of up to 80 meters, there are areas where the forces from the main wind load significantly depend on the method of its determination. The conducted research indicates the ambiguity used in the practice of designing the parameters of the wind load, allowing the possibility of excess or underloading of structures or individual elements.
