Authors: Mustaev R N , Kerimov V Yu , Ismailov J J
Published: March 2021

The article analyzes the evolution of hydrocarbon systems in the Tersk-Caspian trough. In general, the modeling results confirmed the existing distribution of oil and gas content across the sedimentary cover of the region. Thus, according to modeling data, confirmed hydrocarbon deposits are located in reservoirs of upper Cretaceous chemogenic limestones in the areas: Andreevsk, Starogroznensk, Khayan-Kort, Pravoberezhsk, etc. The degree of reservoir saturation, excluding field development, is high – up to 80-90%. Subsalt bundles of the upper Jurassic may become promising objects for searching for hydrocarbons. According to the results of geological and geochemical modeling, there are significant volumes of hydrocarbons in the advanced anticline folds in the upper Jurassic subsalt deposits. The oil saturation here can reach 80% or more

Published: March 2021

In this paper a comparative assessment of the efficiency of electrical and thermal energy production and consumption in a particular region of the Arctic areas of the Republic of Sakha (Yakutia) is presented. Based on the analysis, the existing threats of power supply are revealed and recommendations for effective power supply of the Ust-Maysky District in the Eastern economic zone (EEZ) of the Republic of Sakha (Yakutia) are given. The relevance of the study stems from the fact that the analysis of cost and not only natural indices of electrical and thermal energy production and consumption has been carried out for the first time and no relevant studies have been conducted in the Republic of Sakha in recent years, especially in the context of each locality and the main groups of consumers. The study allows us to propose recommendations for efficient electricity consumption in the context of the settlements of the Ust-Maysky District of the Eastern economic zone of the Republic of Sakha (Yakutia).

Authors: Pershin G D , Kosarev L V , Karaulov N G
Published: March 2021

Research objective is improvement of engineering methods for calculating the main indicators and parameters of the process of cutting rocks with a carbide tool. The sawing coefficient is defined as the ratio of the total forces that arise during the cutting of rocks with a carbide tool. Numerical estimation of the coefficient is conducted using two methods, both on the basis of experimental data from previous studies, and according to the developed analytical theory for calculating the system of contact forces, which characterize the resistance of the rock material to shear and compression deformations. Energy-power assessment of the process of separation of the surface layer of rock with cutting tool is reduced to determination the system of contact forces, which on the one hand characterize the resistance of the rock material to compression and shear deformations (reactive forces), and on the other - acting from the cutter to the rock active forces. The conducted research makes it possible to calculate the effective power spent on the cutting process, as well as to determine the share of energy that goes to the destruction of rock, tools and heat generation as a result of mutual friction. These results will be in demand by production companies engaged in the extraction, processing of facing stone and also design of stone-cutting equipment.

Investigations of the Liquid-Jet Gas Pump’s Mixing Throat Lengths for Well Operations and Associated Petroleum Gas Utilization
Authors: Karabaev S D
Published: March 2021

One of the solutions of water-alternating gas injection technology and utilizing of associated petroleum gas enhancement is application of pump-ejector system technology, which uses a liquid-jet gas pump (LJGP) as a water and gas mixer. This paper is devoted to the test bench studies of the LJGP’s performance characteristics with change of the mixing throat’s length at excess pressures of the ejected gas. As a result of the bench studies, it was obtained that the excess pressures of the ejected gas Pin
require a different approach when choosing the optimum length of the LJGP’s mixing throat, as compared to atmospheric pressure. So, it was determined that at Pin from 0.05 to 0.18 MPa, a long mixing chamber should be chosen, and Pin from 0.18 to 0.6 MPa, the optimal length is medium. It was also obtained that with an increase in Pin
, the optimum working range of the mixing throat lengths increases, which makes it possible to select the mixing throat in wider ranges, without losing the efficiency of the LJGP. With the optimal length of the mixing throat, the highest gas injection coefficients were in the range of Pin
= 0.2 – 0.5 MPa.

Authors: Danilov D A , Vayman A A , Yanush S Y
Published: March 2021

Changes in the agrochemical state of old arable soils on two-membered sediments under the formed mature stands of pine and spruce in the Leningrad region of Russia are considered. It is noted that different pH and organic substances content of soil profile is observed depending on rock composition and granulometric condition of soils. The greatest acidification of all horizons along the soil profile occurs in stands with spruce predominance. At all objects studied the humus content is higher in the horizon of formed forest soil. The largest organic substances stock in the former arable horizon is found in areas dominated by pine. In general, in the investigated sites with spruce and pine stands in the soil complex, the amount of mobile phosphorus (P2O5) decreases as the pH value increases along the genetic horizons. As for mobile forms of potassium (K2O), the dependence of its content reduction on the genetic horizons of the soil in the bottom profile from litter to loamy bedding is observed, where there is some increase in its content. High potassium content in postagrogenous soils under the forest indicates the ability of the soil to keep its level in equilibrium for a long time. The return of the former old arable soils and the native state has not yet happened.

Fluid accumulation is not always easy to predict and recognize because a thorough diagnostic analysis of the well data is required, but accurate prediction of the problem is vital for timely action to be taken. Three methods are considered for determining the minimum required flow rates for the removal of water from flooded wells under the Yamburgsky conditions.
Influence of Climate Change and Anthropogenic Impacts on Worldview of Indigenous Northern Nations (as Exemplified by the Verkhoyansk District)
Authors: Vasil’eva G S , Starostin V P
Published: March 2021

This article examines global climate changes occurring in the Arctic region of Yakutia through the consciousness of the indigenous peoples of the North as expressed in their mythology. It turned out that the small numbered people native to this territory for hundreds of years preserved and continue mythologizing the changes they see in the surroundings while adapting to them and interpreting them according to the folk wisdom, mythological images, and ethnic moral standards. While the global changes have been scientifically rationalized, the locals do not see these changes as disastrous, which allows them to go on surviving in extreme climate conditions, even though adverse natural, industrial and anthropogenic impacts on their lifestyles, health, and moral standards should not be underestimated. Besides, the authors focus on the correlations between the meteorological factors and the disease rate among the local populace. The dispersion analysis methods were used and explained to illustrate this causal link. The authors pioneer in combining and comparing modern scientific knowledge of the life of the northerners, the impact of various adverse factors on their lives, and the folklore of the indigenous Northern peoples. This research used general theoretical and empirical methods, and to some extent, specialized methods including cross-subject methods to analyze the complex environmental, economic, and spiritual processes and phenomena in the lives of the indigenous peoples in the Arctic region of Yakutia.

Published: March 2021

In accordance with the scheme of the experiment animals in the control group received the basic diet (BD), Experimental Group I–BD + feed additive, replacing 30% of the concentrated part of the ration with the inclusion of salts of sulfates of cobalt and manganese, Group II – BD + feed additive, replacing 30% of the concentrated part of the ration with the inclusion of nano - and microparticles of cobalt and manganese.

In situ studies found that the dry matter digestibility of feed additives containing chemically pure metal particles of cobalt and manganese and inactivated feed yeast was 15.4-20.0% (P<0.05) lower than in additives with wheat bran. However, when simulating rennet digestion (in vitro), it was found that the dry matter digestibility of feed additives containing chemically pure metal particles of cobalt and manganese and inactivated feed yeast increased by 1.5-2.2% in relation to additives containing wheat bran. Comparing the availability of pure manganese, we note that in the mixture with feed yeast, it was higher than with bran by more than 2.6 times. Similar values were observed for its inorganic form.

In recent years, the export volumes of Russian coal to the Asia-Pacific countries have been continuously growing. Coal dust is among of the strongest air pollutants. The article describes the study of airborne particulate matter in large transport hubs of the Primorsky Krai (Russian Far East): Nakhodka city and Posyet urban-type settlement using the method of measuring the mass and quantitative concentrations of particulate matter. It is shown that the air of these areas is polluted with particulate matter with diameter below 10 microns (PM10). The absolute dominance of 0.3 μm and 0.5 μm particles was revealed in the air of both areas. According to the Russian hygienic standard, the maximum permissible concentrations of PM were exceeded only at several sampling points. However, when compared to some international standards, the content of PM exceeded maximum permissible values at 42% of sampling points in Nakhodka city and at 43% of sampling points in Posyet settlement. It is advisable to install systems for continuous environmental monitoring of air pollution with coal dust particles near coal terminals.

Authors: Pinigin D D , Nikolaeva N A , Nogovitsyn D D
Published: March 2021

Environmental monitoring studies are of primary importance to assess the characteristics of anthropogenic changes in the environment on the territory of the Elginsky coking coal deposit, which is one of the largest resource potential of the Republic of Sakha (Yakutia). Due to the inaccessibility and territorial remoteness of the field, remote research methods are a valuable tool for environmental monitoring. The article shows the experience of using the satellite image analysis method for assessing anthropogenic impact and spatial detection of changes in the components of the natural environment in conjunction with field study. On the territory of the Elginsky deposit there is a complex of production, infrastructure and linear structures: coal mine, processing plant, hydraulic structures, shift camp, power transmission lines, roads and railways, as well as a railroad bridge under construction. Technical structures interact with the components of the natural environment and modify them, forming geotechnical (geotechnical) systems. Two geotechnical systems were considered in the article: (a) ‘Elginsky coal mining complex - natural environment’ and (b) ‘River – Bridge’ on the Undytkan River, formed as a result of interaction of the valley of the Undytkan River and a complex of linear road structures of railway track “Ulak – Elga”. And the analysis of high-resolution satellite images, as well as data from expeditionary ground-based studies, made it possible to establish that the formation and functioning of the transport geotechnical system led to a change in a number of components of the natural environment — mesorelief, hydrological parameters of surface waters, inhibition of vegetation cover, and changes in soils associated with increased water level, as well as with icing processes.

Authors: Filatov E A
Published: March 2021

During the rapid flow of events of the XX century, there were structural changes in the world economy, which provided all the observed scientific and technological progress. High-tech industries have become the main factor in the development of world scientific and technological progress. In the second half of the XX century, a special category of technologies, industries and products was formed, which were called «science-intensive» or «high-tech». Before the next global financial crisis, it is most important to study the impact of the level of knowledge intensity of invested capital on economic efficiency. The article deals with the analysis of the knowledge intensity of invested capital. Knowledge intensity is an important parameter for determining the efficiency of the economy. The author introduced into scientific circulation indicators: knowledge intensity of invested capital, science intensity of gross regional product and investment return of gross regional product. The article reveals the influence of factors influencing the change in the knowledge intensity of the invested capital of the Irkutsk region of the Russian Federation and gives the author’s methodological approaches to its calculation (the author’s methods of factor analysis). The article presents the author’s analytical, systematic statistical material for the analysis of key indicators revealing the impact on the change in the knowledge intensity of the invested capital of the Baikal region of the Russian Federation (Irkutsk region, Republic of Buryatia, Zabaikalsky Krai). The paper is produced in the framework of the scientific project of the Siberian branch of the Russian Academy of Sciences No. XI.174.1.4 «Activation of the internal development potential of regions of the resource specialization (on the example of the Baikal region)».
Development of Sea Ports in the Far East of Russia: Economic Aspect
Authors: Gudkova E V , Zaostrovskikh E A
Published: March 2021

In the work, within the framework of a new model for the development of the Russian Far East, the trends in the development of seaports for the period from 2000-2019 are studied. In this vein, a theoretical and methodological platform has been studied, which is used in the analysis of the relationship between the port and the region’s economy, and an assessment of the economic effects for the region from the implementation of large projects in the medium term has been carried out. A quantitative analysis of the interdependencies between the specialization of the port and the regional economy was used. It has been established that the implementation of these projects in the medium term will not have a significant impact on the port region: the economic effects will gradually decrease, and the negative consequences will increase. Leveling transport costs through tax incentives of the Free Port of Vladivostok, on the one hand, will create competitive advantages for Russian cargo in the international market, and on the other hand, will stimulate a negative impact on port regions. The economic activity of the ports will not cause a chain reaction of industrial production growth in the port region. Consequently, ports can act exclusively as ports that affect the economy of the port region only through an increase in the volume of their work. For this reason, the priority issue in the development of coal ports in the medium term is the creation of modern specialized terminals with reliable environmental protection, which would combine social, economic and environmental values.

Authors: Antonova A V , Zheleznov Y A
Published: March 2021

The present research featured the level of cross-border water pollution in a resource- type region. In spite of the fact that the cross-border water pollution abatement spans more than half a century of experience, its actions rarely go beyond administrative measures, which is why the problem remains as relevant as before. Nevertheless, all stakeholders are highly interested in solving the issue, which means that the existing measures have to be tested for performance. The issue requires new recommendations on the convergence of various highly effective institutional arrangements. The article presents a rationale for assessment and analysis of the composite indicators of measures aimed at solving the problem of cross-border water pollution. The authors believe that performance should not be confused with the actual solution of the problem, not to mention reaching the goal of sustainable development on a particular territory. The research delivered some practical recommendations concerning the matter of cross-border water pollution in a resource-type region. The recommendations go beyond the scope of administrative management and focus on inter-municipal cooperation and eco-compensation trade schemes.

Authors: Baryshnikova N A , Dushevina E M , Kiriliuk O M , Naidenova N V , Shkryabina A Y
Published: March 2021

At the present stage of development of the world and Russian economies, research on problems in the field of human capital development in its close relationship with economic growth is due to the transition to digital technologies and qualitative changes in the labor market. In Russia, these processes are complicated by persistent imbalances in regional development. The economic lag of regions, which is also caused by the low level of development and quality of human capital, leads to the formation of institutional traps: low incomes, reduced returns on education and, as a result, lack of motivation to invest in human capital lead to increased regional inequality and create a vicious circle. The authors justify the need to develop a regional policy in the "poor" and "middle" regions aimed at developing and improving the quality of human capital by increasing public investment in education. In addition, the article highlights barriers to quantitative growth, qualitative development and effective use of human capital in Russian regions.

Authors: Filimonova I , Chibilyova V , Sviatokha N
Published: March 2021

Recently, it has become obvious that local recreational resources should be utilized. This is connected to the spread of coronavirus which led to the development of local and regional tourism as the only available opportunity to fulfill the recreational needs of people. Tourism companies are forced to search for new types and forms of recreation. Archaeological tourism is one of the types that have been growing in popularity in recent times. In Orenburg oblast, a model steppe region and a birthplace of many ethnicities, both nomadic and settled, archaeologists found over a thousand objects of material archaeological heritage. The archaeological tourism in the region, however, is not widely spread due to, among other things, the insufficient promotion and inefficient positioning of attractions promising for this kind of tourism.

This article deals with the identification and classification of archaeological tourism resources in the steppe zone that led to the mapping of the most promising tourist attractions and the compilation of recommendations on the development of archaeological tourism in the region. The archaeological sites that are the most attractive for archaeological tourism include the Kar-galy mines and the Alandskoye settlement site that belongs to the archaeological group of set-tlements known as the Country of Towns.

One of the recommendations concerning the development strategy for archaeological tourism suggested by the authors is to take into account the desires of the potential tourists from the neighboring Republic of Kazakhstan.

Authors: Krivelevich M , Berezhnova E
Published: March 2021

Internationalization of the world trade and severe competition for the position in global value chains stimulate countries all over the world to create special economic zones (SEZ). For the Russian Far East, the SEZ are the major element of fostering industrial growth and overall economic development. There are Free Port of Vladivostok, Territories of Advanced Economic Development and other development programs created to ensure inflow of investors into the economy of the macro-region. The state offers both tax deductions for up to 10 years and direct budget expenditures for creating infrastructure for the future project sites. Natural consequence of that is the problem of very different financial efficiency of potential projects and dire need to sort or filter those projects that will, probably, be mutually beneficial both for investor and for the state budget from those that, again probably, will benefit only one party or even fail for both. We started from applying standard mechanisms of project evaluation, based on sum of the discounted cash flows comparing to discounted investments, and then enrich it with instruments of working with probable events to make it more flexible. Then based on real-options approach, we show an anticipated cash-flow as the representation of project’s efficiency and create strategy matrix for private and public parties of the cooperation.

In this work the technique of improvement of transport and technological vehicles maintenance is presented. A high-quality organization of technical service is impossible without determining the characteristics of the intensity of requests for a certain type of repair work. The failure flow as a set of successive failures of parts and assembly units is considered as a stationary Poisson process. The check of the stationarity of the failure flow was carried out using the Pearson criterion. The presented technique for researching the failure flow can be extended to any structural elements of technological machines. The results of calculations using this technique can be used, for example, to organize a rational supply of spare parts in order to reduce downtime and material losses during the technical operation of equipment.
About One Task of Managing a Hierarchical System
Authors: Khayrullin R Z
Published: March 2021

The metrological support system for special equipment and special objects considered in the paper is modeled by a three-level hierarchical system. The metrological support system is considered as park of measuring equipment: high-precision instruments installed, working standards and working measuring instruments in a hierarchical sequence. The statement and solution of the problem of program - target planning for the development of the measuring equipment park is given. The goal of the development of the park is to provide the required number of verifications with working measuring instruments. The verified devices are measuring devices installed at special techniques and special objects. As the control actions on the park, the procurement of high-precision installations, working standards and working measuring instruments is strictly used in a certain proportion, determined in accordance with the hierarchy of the system

The mathematical model of the relationship between hierarchies is proposed. The model is based on the equation of the temporal balance of the park’s potential power and the required amount of time for verification, taking into account the frequency of verifications. In the general case, in a hierarchical model, correspondences between levels can be of the type: one to one, one to several and several to one. This circumstance leads to the necessity of solving NP – complete problem of discrete optimization. The article gives an algorithm for setting this NP – complete problem for different cases of violation of the uniqueness of correspondence between elements of different levels. The effective algorithm for estimating the dimension of this problem has been developed. Assessment of the dimension of the problem allows you to choose the appropriate algorithm for solving the discrete optimization problem (branch and bound method, genetic algorithm, ant algorithm, exhaustive search method). The results of mathematical modeling are presented.

Authors: Iurieva L V , Dolzhenkova E V
Published: March 2021

The article contains the author’s methodological toolkit for managing the financial stability of an industrial enterprise, as well as the results of its use. To manage the financial stability of an industrial enterprise, it is proposed to form signal indicators that allow evaluating the work of circulating capital management. For this, it is proposed to make evaluation according to the following groups of signal indicators: indicators characterizing the level of receivables; indicators characterizing the level of external obligations of the enterprise. The result of the author’s algorithm use is the determination of the integral indicator of financial stability, the value of which includes three components: structure indicators, dynamics indicators and indicators of the intensity of the obligations use. The specific weight of each group was determined by expert judgment and is associated with the recommended values of signal indicators. The results of the calculations show that the use of signal indicators in the management of the financial stability of an industrial enterprise makes it possible to timely identify and eliminate problems in the regulation of circulating capital and to increase the financial potential.

In the context of the aggravated economic crisis in many countries, including Russia, there has been a sharp decline in investment activity in the real estate market in recent years.

In conditions of economic crisis, invariably there is a drop of supply and demand in the property market on the one hand due to the decline in real incomes, on the other hand the growth of prices for construction materials which in turn leads to increased property values. The increase in inflation also provokes a reduction in investment activity. [7]

Accordingly, all this leads to the fact that Russian investors began to refrain from real estate development projects. Construction of capital commercial real estate objects in Russia currently has a low profitability and a high risk of loss, as the price of objects decreases while the cost of materials and labor increases. Against the general background, the share of the transactions in the secondary market of both residential and commercial real estate is growing, this is primarily due to the increase in profitability from renting out real estate.

The functioning of any complex system is usually assessed by observable parameters that are obvious to the researcher. Depending on the complexity of the system, there can be a fairly large number of such parameters (indicators) that can be measured based on existing measurement systems (scales). This is especially true for complex socio-economic systems. In this regard, at least two main tasks arise: how to determine the state and dynamics of the entire system as a whole and what is the influence and mutual influence of the elements of the system among themselves. One of such complex elements is the production potential of the region, the state and dynamics of which cannot be directly assessed. Usually, to assess it, indices, regression relationships, and an assessment of its main components (primary indicators) are used. This article discusses an approach based on the assessment of production potential using indicators derived from factor analysis. Factor analysis makes it possible to reduce the number of observed features (indicators included in the assessment of production potential) by searching for a smaller number of hidden (latent) factors (we called them indicators). The same approach was used to search for indicators reflecting the socio-economic development of the region. The article also examines the impact of the level of development of production potential on the socio-economic development of the region. At the same time, primary statistical indicators processed using factor analysis were used as the basis of the evidence base. Identified indicators reflecting the development of individual components of production potential. A rating assessment of the regions of the Central Federal District was carried out according to the proposed indicators.

For effective management of the commercial real estate, it is important to determine the capitalization rate. For this purpose, the revenue approach is used. In order for the result to be real for each segment of commercial real estate, it is important to determine the capitalization rates as accurately as possible. This article discusses two methods for calculating the capitalization rate. For the purity of the experiment, the same commercial real estate items in three different segments were used for both methods. This is an office, retail and industrial warehouse. Based on the comparison, one of the two options is selected, which is optimal and detailed. All calculations were made on the example of the city of Yekaterinburg. The time period is six months. Based on the experience gained, the authors suggest using the data obtained for further calculation of the capitalization rate. For clarity of the results obtained, graphs of the dependence of values were compiled. To calculate this indicator, the authors formed a sample of 26 pairs of offers that were simultaneously in the status of full sale and lease. The article presents a constructive and consistent analysis of the capitalization rate calculation using various methods, as well as informative conclusions. We hope that this method will be useful for practical evaluation.

Published: March 2021

Currently, the use of additive technologies is becoming relevant instead of traditional production technologies. The market offers a fairly large selection of 3D printers with different designs and kinematics. Each design and kinematics has its own disadvantages and advantages. The article demonstrates various versions of the kinematics of FDM 3D printers, the main units and parts, as well as their impact on the quality of 3D printing of parts. The results of structuring the quality function (QFD) and analysis of the types and consequences of potential inconsistencies (FMEA) of an FDM 3D printer for prototyping and manufacturing parts and assemblies for unmanned aerial vehicles are presented. A qualimetric assessment of the quality of FDM 3D printers with various kinematics design based on the QFD interconnection matrix was carried out. The aim of the study is to analyze the design and kinematics of FDM 3D printers for the manufacture of high-quality parts and assemblies for unmanned aerial vehicles without further post-processing based on the application of the QFD methodology. Based on the results of the study, recommendations and proposals for improving the design of FDM 3D printers were developed.

Published: March 2021

The implementation of the reform of the solid municipal waste management system (MSW) consists not only in creating the necessary infrastructure for collecting, transporting, processing, recycling and disposal of MSW, but also the necessary organizational and managerial (territorial schemes for handling MSW, investment programs, the creation of specialized institutions, in particular, the Russian environmental operator, etc.) and financial and economic (tariffs, financial instruments, economic levers, mechanisms for attracting investment) tools. The paper considers the possibilities and advantages of using project financing as a mechanism for attracting private investment in the MSW management system. The conclusions and practical results can be used by the bodies authorized to carry out the reform of the MSW management system, while creating favorable conditions for the development of the project financing mechanism in the MSW management system and improving its effectiveness.
