Abstract
Basic spatial and temporal regularities for development of the processes of generation, migration and accumulation of hydrocarbon fluids in the eastern part of the Scythian platform are determined and particularities of the generation and accumulation hydrocarbon systems in the northern platform boundary – Karpinsky ridge-Mangyshlak and Eastern Ciscaucasia oil and gas producing rocks are studied on the basis of application of the techniques for basin analysis and modeling of the hydrocarbon systems. The results of studying and modeling of the hydrocarbon systems prove that five hydrocarbon systems– Triassic, Jurassic, Cretaceous, Paleocene-Eocene and Oligocene-Miocene generation and accumulation hydrocarbon systems (GAHS) – can be defined within the sedimentary mantle of the eastern part of the Scythian platform. Two-dimensional models based on the regional seismic profile crossing the tectonic elements in the eastern part of the Scythian platform were created using the Temis Suite software package. Main directions for further performance of prospecting and appraisal works in the eastern part of the Scythian platform were determined on the basis of the performed investigations and modeling of GAHS. Differentiation of the investigated area is performed in terms of the type of predicted oil-and-gas content, age of the promising oil and gas complexes and their confinedness to the tectonic structures and zones.

Published: February 2022

Abstract
We assessed the prospects of lentil cultivation in the Russian Federation and the most favorable regions for this. The following tasks were set: we assessed the importance of lentils in the country’s economy, identified promising regions for growing lentils, taking into account agronomic and economic conditions. When analyzing suitable regions for lentil cultivation, not only the agrotechnical conditions of cultivation were taken into account, but also economic factors, for example, the proximity and volume of sales markets, including exports. The selection of promising regions for growing lentils was made on the basis of its agrobiological properties, existing cultivation volumes and agro-climatic conditions of the regions of the Russian Federation. The impact of global climate change and the dynamics of lentil cultivation volumes in recent years were taken into account. Canada, as one of the world leaders in growing lentils, is located at the same latitude with the regions of the Saratov and Volgograd regions. In Russia, the Saratov and Volgograd regions are in good soil and climatic conditions for growing lentils. The high gross harvest was the result of an increase in the acreage under lentils, the value of which in 2019 amounted to 274 thousand hectares, which is 3 thousand hectares more than last year. The production of lentils is going on with a noticeable increase, which is due to the significant orientation of the cultivation of this crop for export. According to the AB-center, in 2015, export deliveries of lentils amounted to 7.4 thousand tons; in 2016-17.2; in 2017-64.6 thousand tons, 2018-77.9 thousand tons; 2019 – 79.8 thousand tons. In the course of research, it was found out that lentils play an important role in the national economy of the country. It is determined that the regions of the Saratov and Volgograd regions are the most promising for expanding lentil production both in terms of agro-climatic conditions and economic potential.
Liquid Energy Reduction with Centrifugal Rotating Motion
Authors: Konoplev N G , Korobkov G E 
Published: February 2022

Abstract
This article provides equation for calculating the pressure loss for a fluid and energy for a rolling ball moving in a logarithmic spiral from the action of inertial forces. Classical formulas give incorrect results when calculating coils with a changing twist radius. The calculation of the parameters of the fluid flow in the spiral bend and in the blades of the centrifugal impeller can now be determined only by numerical methods of calculation and, as such, formulas reflecting the energy losses associated with inertial forces do not yet exist. Based on the results of experimental and theoretical work, formulas were obtained that describe the energy losses of a liquid and a ball, when they move along a logarithmic spiral. For the correct derivation of formulas for a moving fluid, it was first necessary to obtain formulas for a rolling ball and a material point. The movement in a logarithmetic spiral is the basis for the movement of particles in a vortex.

Lactation Characteristics of Red Steppe and Simmenthal Cows in Yakutia
Authors: Zakharova L N 
Published: February 2022

Abstract
This article considers the comparison of the lactation characteristics of local and imported cow breeds.
The winter rations of milk cows contain 9.4 EFU of fodder and 1139 g of digestible proteins, which is 89.9 and 107% of the feeding reference values. The rations comprise 36% of bulk feed, 24% of succulent feed, and 40% of concentrated feed. The proportion of sugar and proteins is 0.43, which means that the content of carbohydrates in the diet is insufficient. The authors established that the research cows had different lactation curve levels even if they had the same housing conditions and diets. For both groups, lactation curves were at the highest during the summer with 5-6 months of lactation and when animals were in the open grazing. The lactation curve of the dairy breed beings to drop rapidly since the 6th month of lactation, and the lactation curve of the local Simmenthal cows reduces more smoothly.
The lactation persistency coefficient for the Red Steppe breed equaled 66.5%. Local Simmenthal cows had the highest lactation productivity of 89.7%.

Published: February 2022

Abstract
In areas of intensive construction on the Arctic coast, river valleys of the Republic of Sakha (Yakutia) non-freezing taliks with a high concentration of pore solution (cryopegs) are found in the strata of permafrost soils. N. P. Anisimova made a great contribution to the study of the cryopegsformation in the cryolithozone [1]. For solutions of any composition, it is established [2] that there is a general dependence of the relative freezing temperature on the relative concentration of the solution. It has also been established that the effect of dissolved salts is additive. The freezing temperature of the solution in the pores of dispersed media is affected, in addition to the concentration and composition of the solution the adsorption capacity of the material in relation to the components of the solution.

Authors: Glyaznetsova Yu S , Zueva I N , Lifshits S Kh , Chalaya O N 
Published: February 2022

Abstract
The paper presents the data on 8-year monitoring of the remediation of disturbed lands and the assessment of the effectiveness of biological treatment of oil-polluted soils. The positive effect of the clean-up work was clearly saw annually for only one summer season. An increase in the level of pollution by the beginning of each next season was most likely due to the oil migration from the underlying soil horizons to the near-surface ones. The data obtained on chemical composition of the soil samples taken from a depth of up to 100 cm showed, that oil content was 2 times higher than on the surface. With depth increasing the amount of hydrocarbon components had become more in the composition of soil extracts, while the content of resins and asphaltenes had decreased. This could mitigate the positive effect of reclamation work.
Interaction of Blast Waves with Multilayer Surfaces and Multiphase Media
Authors: Chernyshov M V , Kapralova A S 
Published: February 2022

Abstract
The possibilities and methods of attenuation of blast waves when they are reflected on any limiting surface in terms of the peak pressure and momentum of the compression phase are of real practical interest. This interest stems from the need to eliminate or maximally mitigate the harmful effects of accidental and terrorist explosions. Porous materials are widely used in a variety of engineering structures due to their superior energy absorption capacity and other advantages in mechanical and physical properties. But when the porous material was used in protective structures to resist an explosive shock wave or high velocity impact, the protective function of the porous material was questionable. There are data indicating both a weakening and an increase in the explosive load on the protected object, depending on the structure of the porous material, the thickness of the protective layer, the duration of the positive phase of the blast wave pressure.

Forecast and Management of the State of the Mountain Range
Authors: Gorbunova N , Mirkushov O 
Published: February 2022

Abstract
This article discusses the safety issues of geomechanical processes in the joint development of oil and potassium salts. The problem is solved by the finite element method. To predict changes in the stress-strain state of a rock mass in the mining area, a method has been developed for calculating the values of rock deflection and reference pressure. On the territory of the Berezniki and Solikamsk districts there are huge areas and valuable salt deposits, and under them - oil fields of industrial importance. Such joint development is unique, and geomechanical processes in this matter are poorly understood. To ensure the safety of mining operations, as well as the safety of ground structures in these conditions, it is necessary to know the stress-strain state of the rock massif and the nature of the manifestation of the movement process during the joint development of oil and potash deposits. Over the ever-increasing excavation space, there is a deflection of rock layers with subsequent subsidence, which both positively and negatively affects the technological processes of production.

Published: February 2022

Abstract
The rapid development of society, increase in the population, land urbanization, growth of human economic activity contribute to the involvement in economic turnover of an increasing number of natural resources, the main part of which is water. Along with the depletion of water bodies, their pollution is also intensively occurring. The analysis of ecological state of basins of small rivers in the South of Russia shows a constant increase in the emission of pollutants into their channels. On the territory of Rostov region there are 5.572 rivers with a total length of 36.064 km. 90 % of rivers of Rostov region are less than 10 km long. On average, a local runoff in the amount of 3.36 billion m3 is formed on the territory of Rostov region per year. Increased anthropogenic activity leads to the disruption of functioning and stability of natural systems, which has a significant impact on small rivers, which are the most common elements of the hydrographic network. About 30 % of urban and about 90 % of rural population live in catchments of small rivers, while the greatest density is observed in the immediate vicinity of water banks. Small rivers significantly affect the hydrological, biological and biochemical regime of landscapes, maintaining the balance and redistribution of moisture and are important for water supply of the population.
Key Profitability Factors for Strategic Alliances in Shipping Industry
Authors: Rusinov I , Ouami A 
Published: February 2022

Abstract
International alliances (or strategic alliances) are combinations of global agreements between linear shipping companies. These agreements were signed in the mid-1990-es, and they include ocean carriers operating the main global routes. Alliances became a crucial phenomenon in shipping in the last few decades. In the past, the cooperation of linear shipping companies stipulated the coordination of prices and volumes. In the last two decades, global alliances of competing companies appear that distribute vessels to increase their operational efficiency and expand service areas. The character of these alliances changed over this period as described in this article. Besides, the authors formulated hypotheses that justify the key determinants impacting the success and efficiency of shipping company alliances. They also provide the results of reliability studies for the data impacting alliance efficiencies, such as the cross-company coordination, organizational training, alliance costs, its duration, and company size.
Analysis of Impact of Urbanization Development on the Deterioration of Ecological State of Rivers
Authors: Bandurin M A , Prikhodko I A , Bandurina I P , Rudenko A A 
Published: February 2022

Abstract
The peculiarity of small rivers is the dependence of erosion-accumulative processes in their beds on the intensity of soil erosion in the catchment area: the smaller the river, the greater the contact with the catchment area of its channel, where mineral particles, washed off from its area, directly enter it. Soil erosion leads to the entry of an excessive amount of them into the channel of a small river, as a result of which sediment accumulation begins in it, siltation of the channel occurs. It leads to changes in the water regime of small rivers - a decrease in inter-soil runoff (up to the drying up of rivers), a sharp reduction in underground power supply. In the humid zone, due to the high water content, the siltation of small rivers is poorly expressed and has a local character. Siltation of small rivers is especially characteristic for the forest-steppe and steppe zones, as well as for the south of the forest zone. In the steppe zone of the European part of Russia, as a result of siltation, rivers of the first order completely disappeared, up to the fourth (up to 40-50 km long), leading to a total reduction of the river network by up to 30 %. In the forest zone, due to the disappearance of sources, the number of rivers of the first and second orders (up to 20 km long) decreased by 2.2 times. During the agricultural period (about 300 years), a layer of sediment with a thickness of 0.5 to 1 m accumulated in the beds and floodplains of small rivers in the southern half of the European part. The erosion of small riverbeds reaches on average only 20 % of washed off products, which is about 60 % of the total river sediment runoff. The rate of siltation of small rivers in the Don basin is 6-12 mm / year with a length of up to 25 km and about 1 mm/year with a length of 100 km and above. Siltation of small rivers is not typical for regions where the soil is washed away by meltwater, since the maximum flow of sediment into the rivers coincides with high water, when the channel-forming activity of water flows is most active.

Published: February 2022

Abstract
The analysis of the current state and prospects for implementation of the integrated land reclamation program in Krasnodar Territory is one of the main tasks in the development of the agro-industrial complex to reduce the risks of industrial safety in the region. The article pays special attention to the crucial importance of the agro-industrial complex of the region in supporting and ensuring food security of the country on the example of Krasnodar Territory, since the Southern region makes a great contribution to the formation and development of the agro-industrial complex of the country. In accordance with the documents of the Program, Krasnodar Territory is a key element in the creation of the “main food base of the country” on the territory of the Southern Federal District on the basis of the formation of a national mega cluster of the agro-industrial complex. The article also pays special attention to the problematic aspects and difficulties in the practice of creating and operating a reclamation complex in the regions of Southern Russia. Taking into account the accumulated experience, the key components of the integrated land reclamation of Krasnodar Territory are identified, providing for improvement of physical and physical-chemical properties of soils through the use of modern irrigation technologies, introduction of new methods for removing excess water during the growing season and expansion of the use of progressive methods of anti-erosion land reclamation. Forecasting the effectiveness of the use of complex land reclamation in the conditions of Krasnodar Territory should show its feasibility and necessity. Thanks to the implementation of comprehensive measures, it is possible to reduce soil degradation, increase the effectiveness of drainage systems, as well as irrigation in general, and ultimately get a positive economic effect. An example of such an economic approach to agricultural lands of Kuban can be the improvement of the overall organic and chemical state of soils, which is mainly reflected in an increase in the gross harvest of agricultural crops.
