Introduction. It is possible to give rise to synergy as a result of science-intensive industries combination with innovative eco-technologies for subsoil use only by developing a brand new approach to nature-like auxiliary technologies. Insufficient adaptability of turbomachines that ensure industrial safety increases the production cost of the mining and oil and gas complexes of the Russian Federation by more than 15%, reducing its competitiveness. Research methodology. Based on the hypothesis of the hydrodynamic analogy of the mechanisms of deceleration of the flow around the airfoil and the formation of its profile resistance, Karman's theory of attached and free vortices, the Zhukovsky-Chaplygin-Kutta hypothesis, the method of conformal transformations, the theory of similarity, the method of singular points by Chaplygin S. A., the criteria for the similarity of natural proportionality are obtained, that is, for the hydrodynamic similarity of the mechanism of energy interaction between the blades of the turbomachine impeller and the wing of a bird. Results. It has been proved that the dominant control over the nature-like proportionality of the aerodynamics of turbomachines is the ratio between the speed and flow acceleration circulation around the airfoil. It has been established that the coefficients of the airfoil resistance, lift and aerodynamic quality of the airfoil cascade are hydrodynamic analogs of the coefficients of the circulation of the velocity and acceleration of the flow and their ratio. Conclusions. It has been experimentally confirmed that the use of the proposed criterion of natural proportionality in the design of turbomachines increases their coefficient of aerodynamic adaptability by more than 2 times, increasing the area of economical operation by 83%.

Competitive growth of enterprises in the mining and oil and gas industries of the Russian economy, combined with industrial safety requirements, updates the task of developing the design and production methodology for the aerodynamically adaptive turbomachines with a nature-like dominance. Such machines adequately and economically soundly establish the necessary parameters of the air environment in the technological space that implement the concept of optimal subsurface management ecotechnology. This article proposes a production methodology for the energy-efficient turbomachines using the aerodynamic adaptability criterion that determines the relations between the velocity circulation and flow acceleration around the vane cascade profiles as the nature-like dominance of the process for converting the mechanical rotational energy of impeller into the internal energy of the air flow. The Karman theory of bound and free vortices, the Chaplygin-Joukowski-Kutta hypothesis, the conformal mapping method, and curve irregularities are used for development of a mathematical model for controlling the aerodynamic adaptability. It is proved that the control dominant is the intensity of the sources distributed over the turbomachine impeller vane profile that determine the flow diffusivity and as a result the acceleration circulation around the profile. It has been experimentally confirmed that the use of profiles obtained using the proposed technique increases the aerodynamic adaptability coefficient of the turbomachine by 51%, while increasing the area of its cost-effective performance by at least 2 times.

Автор статьи выявляет неверную квалификацию так называемого грузино-осетинского конфликта, вызванную ошибочной исторической интерпретацией международной правосубъектности сторон конфликта. На основании метода исторко-правового анализа документов и норм национального и международного права в настоящей статье описывается факт вхождения единой Осетии в состав РСФСР в 1921 году. На основании этого факта в статье рассматривается правосубъектность двух суверенных государств (ГССР и РСФСР) в контексте правомочности их юрисдикции на территории Осетии, для политико-правового анализа ответственности каждого из них за нарушение целостности Осетии и этнического суверенитета осетин. В силу неделимого качества этнического суверенитета осетин, она путем самоопределения могла быть передана только одному федеративному государству – Российской Федерации. Автор статьи квалифицирует конфликт как грузино-российский, что открывает совершенно новый подход к урегулированию конфликта посредством переноса его на открытый равносторонний международный уровень. Investigating the problems of the so-called Georgian-South Ossetian confl ict, the author of the article revealed an incorrect qualifi cation of the confl ict caused by an erroneous historical interpretation of the international legal personality of the parties to the confl ict.Based on the method of historical and legal analysis of documents and norms of national and international law, this article reveals the fact of the entry of united Ossetia into the RSFSR in 1921. Based on this fact, the article examines the legal personality of two sovereign states (the SSR of Georgia and the RSFSR) in the context of the legitimacy of their jurisdiction on the territory of Ossetia, for a political and legal analysis of the responsibility of each of them for violating the integrity of Ossetia and the ethnic sovereignty of the Ossetians. Due to the indivisible quality of the ethnic sovereignty of the Ossetians, it could be transferred by self – determination to only one federal state-the Russian Federation. Due to this fact, and the impeccable international legal personality of Georgia and Russia as actual members of the UN, the author of the article qualifi es the confl ict as Georgian-Russian, which opens up a completely new approach to resolving the confl ict by transferring it to an open equilateral international level.

The article is devoted to the quality of well casing at the Pyakyakhinskoye oil and gas condensate field. The issue of improving the quality of well casing is associated with many problems, for example, a large amount of work on finding the relationship between laboratory studies and actual data from the field; the difficulty of finding logically determined relationships between the parameters and the final quality of well casing. The text gives valuable information on a new approach to assessing the impact of various parameters, based on a mathematical apparatus that excludes subjective expert assessments, which in the future will allow applying this method to deposits with different rock and geological conditions. We propose using the principles of mathematical processing of large data sets applying neural networks trained to predict the characteristics of the quality of well casing (continuity of contact of cement with the rock and with the casing). Taking into account the previously identified factors, we developed solutions to improve the tightness of the well casing and the adhesion of cement to the limiting surfaces.

Abstract The creation of an effective system of rescue support (the abbreviation ASO is adopted on the territory of the Russian Federation) in the implementation of the processes of oil and gas production and transportation in the Arctic seas of Russia is an urgent and difficult task. The feasibility of creating such a system for offshore oil and gas production facilities is due to the statistics of accidents and incidents at such facilities, as well as the fact that the Merchant Shipping Code of the Russian Federation, in essence, does not consider the applicability of the existing system of rescue operations on platforms that are exploring and developing mineral and other non-living resources the seabed and its bowels. The successful solution of numerous problems of rescue support, including the requirements for the quality of the system, indicators and criteria for the effectiveness of the operations carried out, can be significantly increased by using mathematical models that make it possible to identify patterns in the processes of performing urgent work, improve the quality of planning, and, consequently, the efficiency of management of various organizational systems. Applied in many areas of activity, the scientific direction "research of operations" is advisable to use when system generation of rescue support within the framework of improving the system of technical regulation of oil and gas enterprises. Determining the effectiveness of a purposeful process quantitatively will allow, on a scientific basis, with the involvement of modern mathematical methods, to solve the problem of increasing the effectiveness of the use of forces and means of the marine rescue support, including the functioning of the emergency support system in the mode of daily and emergency activities, as well as the preparation of the necessary forces and means. The novelty of the presented work lies in the application of the provisions of the theory and the apparatus of operations research to assessing the effectiveness of the system of the marine rescue support, which will further serve as a methodological basis for the development of a number of documents and provisions that are of practical importance: methods, requirements for the system of rescue support, documents in the field of control over the rescue system, etc.

In the analyzed materials of industrial incidents investigations, there is an incomplete volume of the established facts of the incidence and the causes of its occurrence. Often, when establishing the causes of incidents, biased decisions are made to establish the degree of guilt of the injured person in case of his gross negligence (from 5 to 100 %). The reason for this is the lack of regulatory and methodological documents regulating the procedures for establishing the fact of gross negligence and assessing the degree of guilt of the injured person as a percentage in an industrial incident. All this leads to an increase in the court proceedings, causing moral and material harm to the injured persons. The purpose of the work is to develop a methodology for assessing the degree of guilt of the injured person (insured) in case of his gross negligence based on of the equity principle of all the persons established by the commission for the investigation of an industrial incident in violation of the occupational safety requirements. The methodology is based on the methods of expert, point estimates and methods of incident analysis. Using this methodology, based on the materials of the investigation of a serious personal injury — the fall from the height that occurred with the driver of the tanker as a result of slipping on the slippery surface without the use of personal protective equipment, the main and related reasons of the incident were identified, the degree of guilt of the injured person and other participants of the event was established as a percentage. The developed methodology is aimed at the implementation of Article 229.2 of the Labor Code of the Russian Federation, makes it possible to bring clarity and transparency into the procedure for establishing the degree of guilt of the injured person (insured). The methodology will be useful for specialists in the field of occupational and industrial safety, state labor inspectors, insurers, representatives of the trade union organizations, i.e. all those who are directly involved in the commission for the investigation of industrial incidents.

In Russia, the reform of the regulatory guillotine is being implemented in the field of control and supervisory activity. It should result in a new regulatory system formed according to the principles specified in the key federal laws: «On state control (supervision) and municipal control in the Russian Federation» (Law on Control) and «On mandatory requirements in the Russian Federation» (Law on Mandatory Requirements) adopted in August 2020. In the field of industrial safety, this process was launched by the Decree of the Government of the Russian Federation № 1192, which will come into force on January 1, 2021. The main provisions are discussed in the article, which are related to the Law on Control and the Law on Mandatory Requirements. The Law on Control establishes the priority of preventive measures aimed at reducing the risk of causing harm in relation to the control activities, the grounds for carrying out control (supervisory) activities, the types of these activities in the forms of interaction with the controlled person and without such, the procedure for presentation of the results of control (supervisory) activity. The Law on Mandatory Requirements establishes that the provisions of regulatory legal acts should enter into force either from March 1 or September 1, but not earlier than 90 days after their official publication, and their validity period should not exceed 6 years. The drafts of regulatory legal acts developed by the federal executive bodies are subject to regulatory impact assessment. With a view to ensuring systematization of mandatory require ments, their register is kept. The federal executive body prepares a report on the achievement of the goals of mandatory requirements introduction. By January 1, 2021, 10 resolutions of the Government of the Russian Federation, 48 federal norms and rules in the field of industrial safety and 9 other regulatory legal acts of Rostechnadzor should be adopted. The drafts of all the documents are already prepared, some of the acts are completing the process of discussion and approval.
