Understanding how species that follow different life-history strategies respond to stressful temperature can be essential to efficient treatments against agricultural pests. Here we focus on how the development and reproduction of C. medinalis is influenced by exposure to different rearing temperatures in the immature stage. We found that low (18 or 22 °C) or high (30 and 34 °C) rearing temperatures negatively affected the immature development and flight performance compared to the normal temperature 26 °C, with higher larval and pupal mortality, lower pupation and eclosion rates and shorter flight duration and distance. Low rearing temperatures significantly slowed down the immature process, but accelerated adult reproduction. However, high rearing temperatures had the opposite impacts. Interestingly, the flight of adults with un-mature rearing low temperatures (18 and 22 °C) significantly decreased their lifetime fecundity and mating frequency, but increased pre-oviposition period of females compared to the control; On contrast, high rearing temperatures (30 and 34 °C) significantly accelerated onset of oviposition and enhanced synchrony of spawning. These results indicate high rearing temperatures in the immature stage are more likely to trigger the onset of migration, but low rearing temperatures induces adults to have a greater resident propensity with stronger reproductive ability.

Direct-acting antivirals for the treatment of COVID-19, which is caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), are needed to complement vaccination efforts. The papain-like protease (PLpro) of SARS-CoV-2 is essential for viral proliferation. In addition, PLpro dysregulates the host immune response by cleaving ubiquitin and interferon-stimulated gene 15 protein (ISG15) from host proteins. As a result, PLpro is a promising target for inhibition by small-molecule therapeutics. Here we have designed a series of covalent inhibitors by introducing a peptidomimetic linker and reactive electrophilic “warheads” onto analogs of the noncovalent PLpro inhibitor GRL0617. We show that the most promising PLpro inhibitor is potent and selective, with activity in cell-based antiviral assays rivaling that of the RNA-dependent RNA polymerase inhibitor remdesivir. An X-ray crystal structure of the most promising lead compound bound covalently to PLpro establishes the molecular basis for protease inhibition and selectivity against structurally similar human deubiquitinases. These findings present an opportunity for further development of potent and selective covalent PLpro inhibitors.

Inflammatory burden is associated with COVID-19 severity and outcomes. Residual computed tomography (CT) lung abnormalities have been reported after COVID-19. The aim was to evaluate the association between inflammatory burden during COVID-19 and residual lung CT abnormalities collected on follow-up CT scans performed 2–3 and 6–7 months after COVID-19, in severe COVID-19 pneumonia survivors. C-reactive protein (CRP) curves describing inflammatory burden during the clinical course were built, and CRP peaks, velocities of increase, and integrals were calculated. Other putative determinants were age, sex, mechanical ventilation, lowest PaO2/FiO2 ratio, D-dimer peak, and length of hospital stay (LOS). Of the 259 included patients (median age 65 years; 30.5% females), 202 (78%) and 100 (38.6%) had residual, predominantly non-fibrotic, abnormalities at 2-3 and 6-7 months, respectively. In age- and sex-adjusted models, best CRP predictors for residual abnormalities were CRP peak (odds ratio [OR] for one standard deviation [SD] increase=1.79; 95% confidence interval [CI]=1.23-2.62) at 2-3 months and CRP integral (OR for one SD increase=2.24; 95%CI=1.53-3.28) at 6-7 months. Hence, inflammation is associated with short- and medium-term lung damage in COVID-19. Other severity measures, including mechanical ventilation and LOS, but not D-dimer, were mediators of the relationship between CRP and residual abnormalities.

Published: October 2021

The relevance of the study is to determine the scale of informal employment, as well as to identify the factors affecting this segment of the economy. In the course of the study, a relationship was established between informal employment and the following indicators: unemployment, investment levels, small business development, and average wages. The relationship between the presented macroeconomic factors was revealed, both in the short term by means of correlation analysis and in the long term by tracking changes in the dynamics of informal employment and the presented macroeconomic factors for the period from 2010 to 2019. This study supports the theory of E. de Soto about the forced specifics of informal economic activity, in other words, when there is no employment opportunity (too difficult) in the official economy, citizens are forced to resort to the informal sector of the economy in order to replenish their well-being. In a situation where welfare increases, economic actors can transform and move to employment in the official economy. However, the data obtained in the short-term period did not find confirmation in comparison with the long-term, on the contrary, they showed the opposite picture, which indicates the heterogeneity of informal employment in Russia. Previously, citizens involved in informal labour relations were assessed exclusively as low-skilled, uneducated employees. Currently, informal employment is more assessed as a certain economic activity with its own specifics. Based on the results of the study, a set of measures was drawn up to help reduce the number of informally employed citizens, and to withdraw some of the informal economic entities into the official economy

Modeling of filtration processes of technological solutions in block underground leaching
Authors:   Transbaikal State University, Zozulya А. , Ovseychuk V. ,   Transbaikal State University
Published: October 2021

PAO “Priargunsky Production Mining and Chemical Association” has been working on reserves of uranium deposits of the Streltsovsky ore field for more than 50 years. During this period, most of the rich ores have been worked out by traditional mining and physical technology. The share of poor and ordinary ores remains significant, but traditional technology does not provide the necessary level of profitability. Therefore, the widespread introduction of physicochemical technology: underground block (BPV) and heap leaching (KV) can be a decisive moment in the continuation of the operation of these deposits. The applied technology of underground block leaching has one significant drawback – a low rate of uranium recovery into a productive solution, which significantly reduces the effectiveness of this technology in the development of poor uranium deposits. To increase the yield of uranium into the productive solution, it is necessary to analyze the entire preparation and leaching process and establish the main reasons for the low rates of transition of uranium to a mobile state. For this purpose, it is proposed to simulate the underground leaching process by building visual models of halos spreading of solutions along shrinked ore mining mass accumulated in an underground chamber. During the simulation, it was found that the distribution of the size classes of the broken ore pieces in the chamber can be predicted at the stage of drilling and blasting operations, and when determining the line of least resistance W and the distance between the ends of the wells, take into account the diameter of the controlled crushing zone R_p. At the same time, 3 zones of granulometric compositions are formed: a re-grinding zone, an optimum zone and a non-carbarite exit zone. The flow of solutions through these zones will differ the more significantly, the higher the height of the chamber. In a zone with larger crushing, an almost steep distribution of the solution spreading front is expected. Accordingly, the smaller the fraction, the lower the front to the horizontal is. The following functions are offered to simulate filtering processes: – it is possible to control the flow of working solutions to the fan of irrigation wells in order to achieve optimal leaching parameters, i.e. to quickly control the process; – knowledge of the law of distribution of irrigation flares makes it possible to select the optimal grid of location of single sprinklers

The relevance of the research is the need to recultivate the waste from the enrichment of gold-bearing ores that lie in the immediate vicinity of the residential areas of Baley city, which have a negative impact on the environmental situation in it, as well as to develop a technological approach to the extraction of gold and silver. The purpose of the study is to study the material composition and develop a technology for extracting precious metals. The object of the study is the stale tailings of the ZIF-1 plant “Baleizoloto”. The subject of the study is mineral composition of stale tailings, content of useful components and their extraction technology, the method and methodology presented by mineralogical and chemical analyses of enrichment tailings. Results. The analysis of the tailings dumps’ state of the gold recovery factories of the Baleizoloto plant was carried out. The contents of gold and other chemical elements, among which arsenic, zinc, copper, antimony, and lead predominate, were determined. The gold content prevails in the stale tailings of the ZIF-1 factory, which processed the ores of the Baley deposit, and is in the range of 1.09-1.37 g / t, on average – 1.17 g/t. This determines the prospects for their primary processing. The gold in the clay-sand fraction of the stale tailings is mainly found in thin accretions with quartz, carbonates, pyrite, arsenopyrite, sulfosols, and tellurides. The field of application is processing of technogenic raw materials. Conclusions. It was determined that the sizes of gold inclusions are in the range of 0.7-0.03 mm, the gold penetration varies from 63 to 91.15, and on average is 82.13; the main impurity in gold is silver with a content of 8.85-37%; the average silver content in the tailings of the ZIF-1 factory is 1.85 g/t; the recommended technological scheme for processing stale tailings of ZIF-1 of the Baleizoloto plant has been developed, including the following operations: photoelectron-activation preparation, pelletizing with active solution, heap leaching, two-stage sorption with bubbling with ozone

Published: October 2021

The article is relevant, as it provides an assessment of the information security of universities. Ensuring the security of corporate information, which is increasingly stored, processed and disseminated using information and communication technologies (ICT). This is a particularly important problem for knowledge-intensive organizations such as universal ones; the effective conduct of their main educational activities and research activities increasingly depends on the availability, integrity and accuracy of computer information resources. One of the more important mechanisms to reduce the number of security breaches, and thus corporate information, is the development and implementation of a formal information security policy (ISP). Although much has now been written about the importance and role of information security policies and approaches to formulating them, there is relatively little empirical material that is incorporated into the structure or content of security policies. The purpose of the article is to fill this gap in the literature through this method of using the structure and methods of authentic information security policies. Having established the parameters and key features of university policies, the article critically examines the concept of information security embedded in the policy. Two important conclusions can be drawn from this study: 1) the wide variety of disparate policies and standards used, whether there will be a consistent approach to security management; and 2) the range of specific issues explicitly covered by university policy, a surprisingly low and highly technocentric view of information security management. This article is one of the first to objectively, rigorously and independently assess the content of authentic information security policies and information security documentation frameworks in a well-organized organizational environment. The article notes that there are four different levels of information policy: “system security policy, product security policy, community security policy, and corporate information security policy.” All policies involve: personal use of information systems, information disclosure, physical security, breaches and hacks, viruses, system access control, mobile computing, internet access, software development, encryption and contingency planning

The review article makes the first attempt to outline a wide geographical spread of translations and studies of Siberian and Northern Chinese Evenks’ texts of XVIII-XXI centuries in Russia and abroad. Studying the reception of indigenous people culture is important for understanding how this process relates to the strategies of ethnopolitics and geoculture in Russia and China. The authors focus on certain research centers and the works of their representatives, which are studying the emergence of Evenk literature and the spreading of Evenks’ creativity in today’s world. The article reveals the outgrowth of Evenks’ texts of the XVIII-XXI centuries’ translations and traces the direction of Evenk culture’s research in Russia and abroad. The study has shown that the reception of Siberian and Northern Chinese Evenks’ texts in various historical periods is uneven and depends on the current social and political situation in the countries that affects ethnodifferentiation vs. ethnointegration strategies and the urgent tasks of ethnopolitics and geoculture

The increase in the efficiency and competitiveness of mining enterprises is limited by the insufficient efficiency and adaptability of the currently used centrifugal pumps. Using the vortex theory of turbomachines, Theorems Stokes’ and Helmholtz, the principles of hydrodynamic analogy and superpositions, a mathematical model of the hydrodynamic calculation of centrifugal pumps with adaptive vortex sources integrated into the impeller blades is obtained. A significant influence on the hydrodynamic parameters and adaptability of pumps of the energy characteristics of adaptive vortex sources has been proved. Criteria for the similarity of the hydrodynamic process of fluid flow in the interscapular channels of impellers and adaptive vortex sources and their influence on the hydrodynamic characteristics of pumps are obtained. Mathematical and experimental modeling uses a regression equation to calculate the parameters of vortex chambers and their impact on the efficiency and adaptability of pumps. The optimal geometric parameters of the vortex chambers, the diameter of which does not exceed 5…7 % of the impeller diameter, increase the hydrodynamic loading by at least 13 %, the nominal efficiency. not less than 6 %, adaptability not less than 8 %. On the basis of the proposed developed mathematical model, after the positive test results obtained on the laboratory pump K 20/30, tests were carried out on the CNS 300-300 pump

Published: October 2021

The antimony industry in the Russian Federation is currently experiencing difficult times. The main enterprise that produces and enriches antimony today is GeoProMining LLC, which owns a processing plant at the Syralakhskoye field (Yakutia), where the ore of the Sentanchansky field is processed, production on a smaller scale is carried out in the Krasnoyarsk Territory at the Udereyskoye field of the Novoangarsky GOK, and associated production is carried out at the Olympiadinsky GOK from the tailings of the gold-antimony ore enrichment. Many fields are not being developed at all. The reason for this is the profitability of the development and processing of antimony deposits, due to the low price of metal and the difficulty of obtaining conditioned concentrates due to the presence of metal oxide forms in antimony-containing deposits. Oxide forms of metal in deposits occur in the form of lenses and films, which complicates the enrichment (extraction) of such metal due to the lack of methods and methods or the high cost of processing. The article presents the relevance of the problem of extraction and processing of antimony ores. The reagent-collector of antimony oxide forms KCSb is presented and, based on its application, the parameters of flotation ore dressing of the Zhipkhosha deposit are developed, which contributes to a significant increase in metal recovery. It is noted that the use of КCSb is more effective in comparison with other known reagents used for the enrichment of antimony oxides. The results of studies of this collector reagent, when it is introduced into the technological scheme of flotation of antimony oxide forms, are obtained, which indicate the feasibility and effectiveness of its use. This fact is confirmed by a technical and economic calculation, according to which the conditional profit is 30-31 million rubles per 1 million processed ore per year. The increase in the resulting products (concentrate) is about 700-800 tons, with a quality (antimony content) of 32-36 %, corresponding to the KSUF-3 brand. This method is recommended for use in various antimony and antimony-containing deposits containing oxide minerals (from 10 % or more)

Published: October 2021

The relevance lies in the need to have objective data to assess the belonging of pyrite outcrops to the day surface to the supra-ore zones of gold deposits of a shallow gold-silver formation based on objective data on its chemical composition and forms of crystals and their aggregates. The purpose of the study is to determine the chemical composition of pyrite, the forms of its crystals and aggregates as typomorphic signs of their belonging to the supra-ore zone of the deposit of this formation. The object of the research is pyrite of the supra-ore zone of the Taseevskoye deposit, which is unique in terms of gold content and reserves. The subject of the research is the chemical composition and forms of pyrite separation. The method and methodology are presented by optical and electron microscopy with the determination of variations in the chemical composition of pyrite and morphological features of crystals and their aggregates. Results. The determination of the chemical composition of pyrite was carried out and it was found that almost all crystals are characterized by a sulfur deficiency, the formula coefficients of which are 1.801–1.939 with a change in content from 48.39 to 52.62 %. In 70 % of the measured pyrite crystals, arsenic is present from 0.72 to 4.78 % the formula coefficients of which are 0.007 - 0.076. In 2 % of pyrite crystals, along with As, antimony was found in an amount of 0.21 - 0.71 %, formula coefficients are 0.006 - 0.007. The forms of pyrite crystals are cubic, cubopentagondodecahedral, rarely cuboctahedral and subspherical aggregates, less often lenticular and veinlet, predominate. Conclusions. For the first time, original data on the chemical composition of pyrite in the supra-ore zone of the Taseevskoe gold-silver deposit were obtained. It is shown that its feature is high arsenic content (0.72 - 4.78 %), which can be an important typochemical sign for determining the belonging of chalcedony-like quartz containing it to the supra-ore zone of a shallow gold-silver formation

Published: October 2021

The article presents the waters study results, the composition of which is formed in various hydrogeochemical and ecological conditions. All investigated waters are ultrafresh: TDS of streams and springs does not exceed 30 mg/l, water of Lake Imandra at sampling points is 40 and 73 mg/l. All waters are calcium bicarbonate, but the lake’s waters have an increased content of sulfate ion, chloride ion, and especially sodium. This composition is due to the influence of wastewater from the Kola MMC. It is shown that the 7 km stream is mainly groundwater discharge; however, judging by the concentrations of heavy metals and aluminum, the lateral soil water runoff also takes part in the formation of the stream’s water composition. For all studied waters, the gross concentrations of Ni and Cu hardly change after filtration through a membrane filter with a pore size of 0.45 μm, that is, these metals migrate in a dissolved form (a combination of colloidal and truly dissolved forms). The similarity of the results of determining the migratory forms of Ni and Cu in ultra-fresh waters by experimental and calculation methods is shown. Therefore, according to the assessment of the ratio of suspended, colloidal and truly dissolved forms of copper and nickel based on the results of an experiment using filtration and equilibrium dialysis, in the waters under consideration, the truly dissolved form of migration of Ni and Cu is predominant. The application of physicochemical modeling using the HydroGeo software package made it possible to show that nickel migrates mainly in the form of the Ni2+ ion, and copper in combination with the organic ligands Cu(FА) and Cu(FА2)2-. In addition, it was found that with an increase in the pH value of waters, the proportion of complex compounds increases and the amount of simple ions Ni2+ and Cu2+ decreases

Published: October 2021

The article is devoted to the current state and prospects of cooperation between the BRICS countries in the field of cinema. The forms of cooperation are presented through the prism of the formed experience, the architecture of the modern system of international relations, the processes of globalization, the actual search for new ways to improve the development strategy. Today, the search for new ways to improve the development strategy and strengthen the overall potential of “soft power”is extremely important for the BRICS members. The first meeting of the BRICS Ministers of Culture, held in June 2015 in Moscow and the draft agreement on cooperation in the field of culture adopted at it, are considered as a starting point for actions on cooperation in cinematography in the aspect of transmitting universal and national values to the world community through the art of cinema. During the meeting, the organization outlined the most promising trajectories of cooperation between the countries, and cooperation in the field of cinema was highlighted as one of the most promising areas. The research focus of this article is to analyze the external pressure factors that encourage BRICS participants to cooperate in the field of cinema, to examine in detail the experience of countries in organizing media platforms for showing films, as well as to predict the prospects for cooperation between the BRICS countries in the field of film production. From the perspective of prospects, the article analyzes such forms of partnership as the formation of the film market, the development of the film business, the creation of professional personnel exchange programs, a joint repository of media materials, international agencies and foundations, holding film festivals, discussions, symposiums, etc. One of the promising areas for developing cooperation between the BRICS countries in the field of cinema is the creation of a single database of actors. Such a project can significantly facilitate the search for the necessary types of directors from the BRICS countries. The participants confirmed their readiness to strengthen and expand cooperation within the framework of BRICS. For this purpose, a BRICS Working Group on Culture will be established, whose members will annually exchange information on multilateral cultural cooperation, as well as inform each other about upcoming large-scale events that will be held in their countries

Published: October 2021

The article aims at monitoring the information content of the websites of municipalities based on the case of Kemerovo Region-Kuzbass, one of the subjects of the Siberian Federal District. The main assessment criteria include such indicators as availability of regulatory information on the website, basic information about the municipality, information about the reception of citizens, thematic range and frequency of filling websites with information, availability of special interactive features, and others. This kind of research is relevant due to the need for further development of democratic practices at the regional level as the official websites of municipalities, along with developing social networks, are today a significant communication channel between the authorities and the population. As before, official websites allow solving a number of communication issues: they disseminate information about current events, ensure the work of “virtual reception offices”, provide an opportunity to make a request or file a complaint about the poor performance of their duties by public utilities. In addition, high-quality and timely updating of information on the websites of municipalities does not only affect the public sentiment with regard to representatives of the municipal level, but also shapes public assessment of the work of all authorities at the regional level – the parliament, the Government of Kuzbass and the head of the region. The monitoring results made it possible to identify a number of recommendations to the regional and municipal authorities of the region, in particular, the need to create a unified modern format of the website structure for all municipalities with high-quality, attractive appearance, the need to unify the structure of official sites for the convenience of both finding information and working with it, and creating special needs versions of websites for the visually impaired (when such versions are absent)

The relevance of the research is due to the need to increase the technological efficiency and efficiency of the production system of shipbuilding organizations in Russia to ensure an increase in the competitiveness of domestic civil shipbuilding products on the world market. The trends of scientific and technological progress in the industrial sector “Shipbuilding 4.0” have been summarized. The definition of the production system of the shipbuilding organization 4.0 has been proposed. The article reveals the industry-specific features of the functioning of the production system of the organization of Shipbuilding 4.0 on the principles of the concept of Industry 4.0, based on the use of modern digital technologies at all stages of the ship’s life cycle. The article considers the main problems of digitalization of shipbuilding and suggests ways to solve them. Special attention is paid to the unsatisfactory state of fixed production assets, low efficiency of shipbuilding organizations, low rates of introduction of innovative technologies, a shortage of qualified personnel, high cost and long terms of ship construction in comparison with foreign competitors. At the same time, some proposals have been formed: the introduction of lean manufacturing, methods of project and production engineering, the development of economic cooperation and industry standardization. The technical and economic features of shipbuilding, which determines the specifics of the digital transformation of production processes of industry organizations, have been determined. It is proposed to consider the production system of a shipbuilding enterprise as an integrated element of the ecosystem that unites all stakeholders throughout the life cycle of shipbuilding products. The key factors of specialization of the shipbuilding enterprise have been highlighted. The implementation of innovative technologies into the activities of Russian shipbuilding organizations 4.0 will increase the competitiveness of domestic shipbuilding products on the world market, creating value for stakeholders, defining new requirements for the organization of activities while reducing production and operating costs, operation execution time and increasing production efficiency

The relevance of the research lies in the need to remove sulphur-containing compounds from coal raw materials at the lowest cost to reduce the environmental load in the areas of coal use. The object of the study is coals of the “G” brand of the Kuznetsk basin of the Kirov mine. The subject of the study is the petrographic and chemical composition of coals, the content of sulphur impurities. The aim of the study is to develop selective reagent flotation modes using inorganic reagents-modifiers. Research objectives: – to determine the petrographic and chemical composition of coals; – to conduct flotation studies using the foam flotation method; – to evaluate the effect of inorganic reagents-modifiers on the φ - potential and hydration of the coal surface; – to determine the mechanism of modifiers’ action on the depression of sulphur-containing impurities of coals. Methodology and methods of research. A complex of physical, chemical and physico-chemical research methods has been used in the work. The degree of scientific development of the topic. A promising direction for reducing sulphur-containing emissions is to increase the selectivity of the flotation process by modifying the coal surface. Results: petrographic analysis of the studied coals has showed that the main micro-component is vitrinite (85 %); chemical analysis indicates that the humidity of the coals is 2.27 %, the ash content is 17.82 %, the yield of volatile substances is 32.90 %, the mass fraction of inorganic sulphur is 0.38 %, organic sulphur is 0.43 %. A comparative analysis of qualitative and quantitative indicators of coal flotation shows that the use of non-organic reagents-modifiers can significantly increase the extraction of sulfur into flotation waste. The analysis of the kinetics of changes in the electrode potential of pyrite indicates an increase in the potential values in the presence of these reagents and a decrease in the hydration of the pyrite surface. The obtained results indicate the expediency of using inorganic salts as modifier reagents that contribute to reducing the sulfur content in coal concentrates due to the depression of pyrite-containing impurities due to an increase in the hydration of their surface

The report is devoted to an attempt to analyze the religious threat as a phenomenon and as a concept used in modern social discourse in the territory of the Russian Federation. The problem disclosed by the authors is that the social discourse, devoted to assessments of religious threats, does not take into account the point of view suggesting the need to comply with the principles of equality before the law of all participants in the social process, including traditional and non-traditional religious associations. The authors conclude that in studies of threats emanating from religious associations, a distinction must be made between non-religious and religious threats. A non-religious threat should be understood as the consequences of destructive extremist activities that cause real damage to human health and life, to preserve the integrity of the state and society. The meaning of the concept of a religious threat consists in dangerous consequences of the religious doctrine influence, which serves as a cause of offending feelings of believers or unbelievers and doing them moral harm. For the practice of regulating religious interaction, it is important to understand that this type of danger, as a rule, is difficult to determine unambiguously due to subjectivity and the presence of different assessments in relation to the consequences of some of those actions

The scientific and practical relevance, timeliness and practical and applied relevance of the selected research topics are empirically substantiated by the processes of sustainable development of world labour markets, improving the quality of human resources, increasing the importance of scientific and educational activities, acquiring unique competencies, knowledge and skills by workers of modern business entities, deepening specialization and differentiation of science-intensive enterprises, permanent scientific and technological progress and acceleration of the pace of formation of industrial-industrial clusters and venture business. The theoretical and practical goals of the publication are to study the socio-economic mechanisms for solving the theoretical and practical-applied problems of sustainable innovative development of the industrial economy and the implementation of science-intensive projects characterized by high production and economic uncertainty and significant socio-economic risk, which are not amenable to formalization. The theoretical and methodological basis of the publication was the scientific works of domestic and foreign scientists-researchers of socio-economic algorithms for the development of domestic and world economies of industry, as well as venture business. Scientific novelty lies in the critical rethinking of such a constructive and creative result of the venture business as the formation of public-private partnerships and the author’s interpretation of strategically significant science-intensive segments of the industrial economy (telecommunication technologies, medicine, microbiology, production of substitute products, innovative energy trends, the search for alternative sources of energy supply, etc. etc.). The practical significance of the results obtained lies in the comparative characteristics of the American and Eurasian strategies for the innovative development of industry, as well as the empirical argumentation of their socio-economic advantages and disadvantages. The article reveals a reduction in costs and a regression of transactions between production and economic services of American companies, savings due to the narrow focus of scientific and production processes with a simultaneous absence of material incentives for labour activity and the occurrence of costs due to the regulation of labour functions of workers. The use of a progressive system of remuneration of labour and bonuses to personnel of Eurasian companies has been established in the context of a simultaneous increase in resource and raw materials and monetary costs and the liberalization of in-house management, which are of priority importance for the formation of a strategy for the development of the Russian industrial economy

The article presents the current problems faced by many of the largest companies in various industries related to the impact of the Covid-19 epidemic. The article describes the countries that have achieved high results in the process of active innovation implementation. It is revealed that financing plays an important role at every stage of the innovation cycle, from the conceptualization of a product, service or technology to their commercialization and subsequent development. Today, relatively new financing mechanisms are widespread, such as intellectual property markets, crowdfunding and solutions in the field of financial technologies. Policy measures to stimulate investment contribute to the emergence of new growth points and the achievement of long-term goals, which is important for the future development of countries. It is proved that the effectiveness of cooperation between countries and their internationally agreed research projects can effectively counter the trend of increasing protectionism and solve important social problems at the present stage and in the future
Dependence of uranium extraction into solution during heap leaching on the petrographic composition of ores

The widespread introduction of physical and chemical geotechnologies in the production of mineral raw materials makes it possible to involve ores that are poor in the content of the useful component, which are unprofitable to work out using traditional physical and technical methods. One of these new geotechnologies is the heap leaching of rocky uranium ores. When planning the volume of output of finished products, it is necessary to have an analytical apparatus that would make it possible, using the acquired knowledge, to calculate the required volume of mineral raw material production and its varietal composition. Based on their task, studies were conducted on the qualitative and quantitative characteristics of ores that affect the indicators of extraction of useful components from them. As a result of the research, the dependence of the index of uranium extraction into a productive solution during infiltration of sulfuric acid leaching on the material composition of ores was established. Ores localized in various lithological differences of acidic, medium and basic rocks were tested: granites, felsites, trachydacites, andesites and conglomerates. The ores were classified according to the size of the piece with the allocation of fineness classes +200 mm, -200 +150 mm, -150 + 100 mm, -100+70 mm, -70+ 30 mm, -30 mm. The tests were carried out in laboratory and semi-industrial conditions. The maximum extraction was obtained for the class – 30 mm in columns. When leaching in stacks, the maximum extraction of uranium into the solution was obtained for the size class -70+30 mm. The reason for the lower extraction from the -30 mm class during leaching in semi-industrial conditions was the processes of mechanical colmatation, due to the large number of fine fractions. The criterion characterizing the material composition of ores is the content of silica (SiO2). During the tests, the dependence of the uranium extraction coefficient in the productive solution on the content of silica in the ores was established. The higher the concentration of silica, the more uranium passes into the productive solution during leaching with a stable composition of uranium mineralization. The dependence is described by a mathematical formula, which allows us to use it to calculate the extraction of uranium into a productive solution, knowing the material composition of ores
