he basic ideas about the process of introducing cores into protective barriers and the most common core patterns and their location in conventional and sub-caliber small arms bullets are discussed. The materials used for manufacture of cores are analyzed. It is concluded that for mass bullets of increased armor penetration the most rational choice can be considered the use of high-carbon low-alloy steels of a new generation with a natural composite structure and hardness of up to 70 HRC. For specialized armor-piercing bullets, cores made from promising economically-alloyed high-speed steels characterized by a high complex of «hardness—bending strength» are better alternative than ones made of hard alloys or tungsten alloys.

Infectious diseases in the modern world continue to claim millions of human lives despite the achievements of medicine. While in developed countries the main cause of death is cancer and diseases of the cardiovascular system, it is the infectious processes that occupy leading positions in the structure of mortality in the third world countries. About 1.7 million children die from infections that could have been avoided by vaccination according to the World Health Organization. In contrast to the countries of Western Europe, where preventive vaccinations for the population are carried out for a fee, preventive vaccination in the Russian Federation is funded by the state. Immunoprophylaxis includes not only prevention of 12 major infections included in the calendar of preventive vaccinations (diphtheria, polio, tetanus, whooping cough, tuberculosis, measles, rubella, mumps, hepatitis B, pneumococcal infections and haemophilus influenzae, influenza), but also vaccination against 17 additional infections in case of epidemiological indications.

Development institutions are an important modern instrument of government regulation of the economy in all developed countries. The system of development institutions of the Russian Federation includes the federal and regional development institutions. Key federal development institutions include such well-known state corporations as the investment fund of the Russian Federation; the State Corporation "Bank for Development and Foreign Economic Activity (Vnesheconombank)"; the state corporation "Russian Corporation of Nanotechnologies," etc. According to experts of the Ministry of Economic Development of the Russian Federation, about 200 regional development institutions operate on the territory of the constituent entities of the Russian Federation. The objectives of this extensive system of development institutions so far have been to overcome the so-called "market failures," which cannot be optimally realized by the market mechanisms, and to promote the sustained economic growth of a country or an individual region. In November 2020, the Government of the Russian Federation announced the reform of the system of development institutions in the country. The article analyzes the goals and main directions of the announced reform. On the example of the system of development institutions of the Far East, an attempt was made to assess its possible consequences.

Risk Categories

Normative legal acts of the Russian Federation establish that the criteria for assigning control objects to the categories of risk of causing harm should be formed based on the results of the assessment of the risk of causing harm. In the developed countries of the world, as a rule, the distribution of objects of control by risk categories and the substantiation of the frequency of their inspections are carried out depending either on the point risk assessment, or on the number and importance of the violations of mandatory fire safety requirements revealed during the inspection of the object of control. The purpose of this work is to substantiate the frequency of scheduled inspections of the objects of control by the state fire supervision bodies depending on whether the objects of protection belong to a particular category of risk of causing harm. As a criterion for assigning control objects to various categories of risk of causing harm, it is proposed to use the risk of causing harm (damage) as the result of fire in the buildings of various classes of functional fire hazard, which is understood as the product of the probability of fire occurrence, the probability of causing socio-economic harm (damage) as the result of fire and the value terms of socio-economic harm (damage). A mathematical model was developed to determine the risk of causing harm (damage) as the result of a fire in a building, and an assessment of its values for the buildings of various classes of functional fire hazard is given. Distribution of the buildings by categories of risk of causing harm (damage) was carried out depending on the calculated value of the risk of causing harm. It is shown that the distribution of control objects by risk categories significantly depends on the degree of detail in the fire record card of the characteristics of the building in which the fire occurred. The optimal terms for carrying out scheduled inspections of the objects of control are proposed depending on the category of risk to which they are assigned. Proposals are formulated concerning the improvement of the risk-oriented approach in the activities of the state fire supervision bodies of the EMERCOM of Russia.

This article explores the vulnerabilities of Russia in the digital environment, as well as such phenomena of modern digital economy as cryptocurrencies, blockchain, big data, artificial intelligence, and robotics. The question is raised on the risks that humanity faces in the digital space, which entail the implementation of the latest technologies in society. The author offers the ways for their minimization. The article covers the project “Digital Economy” developed by the Government of the Russian Federation, which is intended for creation of sustainable and secure information and telecommunications infrastructure for high-speed transmission, processing and storage of data bulk, accessible to all organizations and households. Analysis is conducted on the modern enterprise in the sphere of information and communication technologies and the concept on the protection against personal data theft. The crucial role of the IT specialists in digitalization is highlighted. The conclusion is made that in digital space, the major threat to national security is the hacker attacks aimed at the theft of personal data, intellectual property, etc. The author believes that the minimization of risks detected in the course of research requires providing technology opportunity for the Russian Federation to store the collected data locally, rather than abroad. The all-round government influence on the research and legislative sphere, legislative orientation towards stimulating the development of innovation technologies would ensure safe and effective integration of socioeconomic sphere into the digital space.

Currently, Russia has declared the need to develop a federal law “On urban agglomerations”; the development of urban agglomerations is declared as a necessary condition for ensuring economic growth and innovative development in the country. However, there are no evident approaches to the allocation and delimitation of urban agglomerations; the definitions given in the Russian spatial development strategy are very general. In this regard, the purpose of this article is to summarize the existing approaches to working with agglomerations in foreign and Russian science and practice. The article shows that in economically developed countries, the main approach to the allocation of agglomerations is functional, in which the area of interaction between the “core” of the agglomeration and its “hinterland” is determined, first of all, by the intensity of pendulum labor migrations; the functional approach is gradually transformed into a network approach, implying the polycentricity of agglomerations. The allocation and delimitation of agglomerations in a country can be based on a unified or individual approach. The article suggests using both options in Russia: a unified approach for improving statistical accounting of changes in the settlement system, which is close to the OECD methodology, and an individual approach for strategic planning and development of inter-municipal cooperation. The advantage of the OECD methodology is that there is no need to rely on the existing territorial boundaries of local self-government, which differ markedly across the subjects of the Russian Federation. It is also proposed to conduct a broad discussion of the approaches to the allocation and delimitation of agglomerations for the law “On urban agglomerations”; to improve the system of statistical accounting for pendulum population migrations, including in population censuses.

The article considers modern condition and development perspectives of transport at whole and the transport infrastructure of Ukraine. The basis of the country transport complex makes up its infrastructure, it joins manufacturing, users, suppliers and partners. Developed infrastructure affects not only effective and timely delivery of the products, but provides for decreased transport expenses. The beneficial geographical position of Ukraine, crossing the main transit ways between Europe and Asia, presence of active Black Sea ports, developed network of railroads, car roads and pipelines throughout the latitudinal and meridian directions create all predispositions for the transport branch development. The studies of the Ukrainian transport infrastructure and transport condition during last years evidence about non-stable dynamics, which is mainly related to economical and geopolitical crisis in the country as well as the COVID 19 consequences. Analysis of the freight transport by transport kinds shows increased volumes of car transport with decreased railway transport. The rise of the car transport share is connected to its advantages: mobility, possibility of delivery exactly to the destination, high speed of delivery, flexibility of the route choice, wide range of the shipment as well as provision of logistic services by cars. Exacerbation in the East has considerably decreased number of contracts between Ukrainian shipping companies and international partners related to the international transportation. First of all, the situation provides for decreased transportation volumes on the territory of Ukraine. The level of transport services to economic system and population of Ukraine is significantly lower than that one in the developed countries of the world. According to the car road characteristics, Ukraine has long been behind not only the countries of Western Europe, but many post-Soviet countries. A necessary condition of the effective development and managing crisis in the transport branch, particularly that caused by the COVID 19 pandemics, is development and modernizing transport infrastructure of Ukraine according to the modern technological requirements. This will provide for uniform development of all regions of Ukraine, improved population life quality, development of trade and tourism as well as creation of new economic opportunities by attracting foreign investment.

Introduction. The nutrition of the Nenets in the Arctic zone of Western Siberia is mainly based on traditional products (raw (thermally unprocessed) local fish and venison), which is the most important factor of survival in the Arctic. Storing up food products for an extended period is not relevant for the Nenets. Climate change and industrial development in the Arctic primarily affect the seasonality of consumption. Changing the calendar of fish and venison harvesting leads to greater use of imported and canned local food, increasing the length of the periods when local food completely disappears from the diet of the Nenets. Material and methods. During the expeditions to the national villages of the Yamal-Nenets Autonomous Okrug, cross-sectional screening studies were performed, in which 985 Nenets people took part. Nutritional analysis was conducted using the questionnaire method based on an album of portions and dishes. Retrospective information was collected on the seasonality of consumption of reindeer products and local fisheries (the length of the period when unserved fish and venison are available). Results. The consumption of reindeer and river fishery products is seasonal. The duration of the season of venison consumption was from 150±14.0 to 180±21.0, and raw fish - from 120±14.0 to 200±21.0 days. Despite the high level of consuming reindeer products per season, the average annual consumption of venison by Nenets in the Arctic zone of Western Siberia was 240 g/day/person that is less than in the central regions of the Russian Federation and industrially developed countries. In the studied area, the average annual consumption of fish (171.5 g/day/person) is three times higher than the average consumption in the Russian Federation. However, increased consumption of traditional food is typically only during the season of fishing or slaughtering reindeer. The average annual consumption reduced; during the off-season, the share of easily digestible carbohydrates in the diet increased. Conclusion. The creation of fish and venison stocks in villages and their year-round sale to the population is a necessary step in ensuring the food security of the Nenets people.
