Authors: Prisnyi A A 
Published: March 2021

Abstract
Excessive concentrations of heavy metals in food we eat are among the current issues of food safety. This becomes especially evident if we consider highly toxic elements such as copper, lead and cadmium. With regard to the foregoing, it would be helpful to get information about use of novel sorbents in livestock farming and their effects on distribution of heavy metals in animal bodies. The drug we study is based on natural mineral raw materials and contains up to 60% of silicon dioxide. It has prominent sorption properties. The drug was introduced to diets of brood sows, growing piglets and finishing pigs in a dose 120 mg/kg of body mass. Lead concentrations in three-month-old piglets decreased by 17% in striated muscle tissue; and in the skin and hair covering of the piglets receiving sorbents there were just traces of lead. In striated muscle tissue of piglets in the control group the cadmium levels were 0.14±0.003 mg/kg, i.e. 2.8 times higher than the maximum permissible concentration. Sorbents introduces to the piglet diet caused decrease in concentrations of this metal by 35%. Use of the sorptive dietary supplement has certain prospects as a method of obtaining organic food.

Published: March 2021

Abstract
This paper attempts to define key trends observed in new-generation mining engineer training today. A comparative analysis, which looked at recent developments in teaching concerned with innovative technology and transformation of scientific knowledge in general, indicates the need for a new educational paradigm. Actual interaction between humans and their environment was taken as a hypothesis about professional knowledge and skills. The role of the axiological components of the new paradigm was revealed in the light of the communication nature of the society. A methodology was developed to build a new-generation engineer model. The paper reveals the role of a learner’s metacognitive ability in the development of new teaching techniques. The paper highlights how important it is that an engineer was striving for environmentally friendly technology. The authors defined the effect of the altered environment on engineering. The paper substantiates why one can only be said to have hard & soft skills if one is able to apply critical and creative thinking. It was found that training an engineer under the new paradigm is inevitably related to the ability to reflect. Analysis of the linguistic modality serves to support this statement.

Published: March 2021

Abstract
The paper is devoted to the analysis of the structural and thickness characteristics of the sedimentary mantle of the northern part of the Surgut arch (Western Siberia, Russia). Based on the results of generalization of the structural surfaces of the Meso-Cenozoic sedimentary mantle reflecting horizons, the specifics of the surface relations have been determined. It was found that the relationship between the reflecting sedimentary horizons controls the oil and gas content of the YUS1 formation in the area studied. To determine the prospective oil and gas content of the area, the relationship between the reflecting horizons has been analyzed in detail. The resulting specifics have been analyzed, and the identification of zones has been justified. Zoning of the study area has been performed. The identified zones are characterized by different structural surface relation patterns and correspond to areas with similar sedimentation conditions and tectonic regimes manifested during the sedimentation period.
Monitoring of Arable Land Fertility Based on Agrochemical Analysis and Dynamics of Changes in Soil Organic Matter Reserves
Authors: Dolobeshkin E V , Gumbarov A D , Bandurin M A 
Published: March 2021

AbstractThe article considers the problems of food security on the example of assessing the initial state of arable land fertility. Agrochemical soil analysis makes it possible to determine the direction of a complex of reclamation measures that can significantly increase soil fertility. The need for this is defined due to the development of degradation processes in the soil, as a result of which the reserves of soil humus and basic nutrients necessary for the productive development of plants have sharply decreased. The authors of the article proposed the evaluation of the initial fertility of arable land on the main agrochemical parameters (humus G, nitrogen N, phosphorus P, potassium K and hydrolytic acidity Ng). Based on the data of agrochemical soil laboratory in the farm "Memory of Lenin" in Krasnodar Territory, an initial average agrochemical state of arable land, which was the initial and maximum index of fertility (S(G), S(NPK), S(Ng) and the composite index of the soil - S). The complex of reclamation measures should be aimed at: increasing the reserves of humus in the soil, as a result of additional input of soil biomass; increasing the doses of mineral fertilizers, bringing the ratio of mineral nutrition elements to the optimal. To determine the trend of changes in the state of arable land, it is necessary to forecast it.

Published: March 2021

Abstract
The article reflects the results of a study to determine the operability of an interval radial-thrust in-line device, intended for use in the repair of the linear part of main gas pipelines. The paper contains information characterizing the stress-strain state of the most wear-out elements of the inline shell. The problem is reduced to finding the equivalent stresses for the initially selected material. The results of the study indicate that under the conditions of a one-sided force factor (pressure) of the gas pipeline medium, the limiting state of the material of the end element is not reached. As a methodological basis for the study, the use of finite element analysis is assumed. The result of the study is a picture of the distribution of equivalent stresses in the plane of the end element.

Published: March 2021

Abstract
One of the parameters that allow us to predict the capacity of forest roads is the speed of the logging truck. It can act as an indicator of the road condition and be used as an optimality criterion for optimizing timber transport processes in the development of forest massive. This article is devoted to the study of the dependence of this indicator on natural and climatic factors when driving on various categories of forest roads at different times of the year. The object of the research is automobile logging roads located in the intensively used logging areas of the Krasnoyarsk territory. To obtain regression equations, the planning of the experiment was performed. Regression models were found that describe the influence of road slope and the amount of precipitation on the speed of a logging truck. The indicated dependencies are obtained for different categories of roads and periods of the year when driving in empty and cargo directions. All equations have fairly high accuracy and are statistically significant. The constructed dependencies are graphically illustrated. The results obtained can be used in planning the development of a road network in the forest area, selecting means, methods, and volumes of wood removal.

Published: March 2021

Abstract
This paper deals with the problems of effluent disinfection due to hydrodynamic cavitation caused by using the biogas technology. Effluent disinfection due to the acting hydrodynamic field makes it possible to destroy pathogenic microorganisms without using chemical reagents. The effect of the hydrodynamic field on microorganisms can be studied experimentally. Therefore, for experimental studies, a laboratory unit to create a cavitation field is developed. The paper presents the methods and results of experimental studies on the effluent disinfection in Venturi tube with the help of the cavitation field. The results of the experiment showed that for the E. coli bacteria group there is a threshold of sensitivity to cavitation action. The liquid flow rate at which the intensity of cavitation can destroy the microbial cell is shown. The dependence of effluent disinfection degree on cavitation regime parameters is established. The results of experimental research prove the efficiency of effluent disinfection in the cavitation field.

Authors: Nikitina M A 
Published: March 2021

AbstractTo make management decisions, it is necessary not only to have reliable data, but to adequately and timely analyze them as well. Applying digital technologies in agriculture, decision support systems for diet formulation with mathematical exactness will allow planning animal’s feeding taking into account many factors (animal genotype, age, seasonality, etc.). The growth and development of animals, their productivity depend primarily on the level of balanced feeding. The article proposes a computer system methodology for evaluating and optimizing the diet of animal feeding based on a structural-parametric model. The advantage of the structural-parametric model of animal feeding is that it considers the whole variety of factors of nutrients influence on the processes occurring in the animal’s body, depending on its current physiological state; allows one to establish patterns, the knowledge of which with a sufficient degree of confidence speaks about possible deviations in feeding, the reasons for their occurrence; allows one to find a solution to replenish the imbalance in the required macro- and micronutrients. The use in agriculture of science-intensive decision support systems based on knowledge of the subject matter experts and strictly verified mathematical methods will increase the productivity of animals and provide a high-quality product with the ability to trace the trophological chain from the field to the counter.

The Operation of a Tillage Tool Smart Control System
Authors: Redreev G V , Demchuk E V , Golovanov D A 
Published: March 2021

Abstract
Studying control systems is associated with a number of problems related to the operation of the system components and the dynamics of links between the components. The development of control systems is required to interact with the changing controlled object. Some continuous processes involve products or media that are significantly longer than the machine used, which has to move to operate. In such cases, it is quite difficult to ensure the proper operation of the control system because of the stochastic properties of the medium and the high movement rate of the mechanism. The problem lies in the lack of knowledge about the content, structure, and operating algorithms of smart control systems for the working tools interacting with the soil as a polyphase medium. The creation of a mathematical model for a smart control system for the tool interacting with the soil marks the employment of innovative digital and smart technologies for cultivation. The tool and soil parameters can be recorded both before and after tillage.
Analysis of the Influence of Temperature and Precipitation on the Beginning of Wood Removal in the Summer

Published: March 2021

Abstract
The purpose of logging roads is an effective carting out of the planned amount of harvested wood. Main problems: the problem of increasing transport accessibility of forest resources; the need to take into account and neutralize the negative impact of factors that affect the carting out of harvested wood; minimize costs across the entire supply chain. All these problems are affected by natural and climatic factors. Based on the analysis of the practical experience of logging companies, the amount of moisture in the ground has a large influence on the start of operation of summer roads. It was found that at the beginning of the summer logging road operation season, in addition to the water and heat regime (precipitation and their amount), the amount of moisture in the soil is also affected by the moisture of meltwater. Retention of meltwater in the soil depends on the freezing of the soil in the autumn-winter period, as a result, the most freezing of soils occurs when there is an excess amount of water in the soil. Research in this area is topical, since the amount of precipitation before constantly falling snow in the autumn period has an impact on the process of retention of meltwater in the ground and has a significant influence on the beginning of timber carting out in the summer. As a result, the purpose of the research is to analyze the influence of precipitation in the spring period, positive air temperature and amount of water in the soil in the autumn period on the beginning of timber carting out along summer roads, as well as to compile a corresponding regression model. The object of this research is data on the dates of the beginning of timber carting out in the summer from the logging territories of enterprises in the Krasnoyarsky kray

Authors: Gorelkina E I 
Published: March 2021

Abstract
Rational use of associated petroleum gas (APG) is the most important task of the oil industry. One of the options for its solution can be the use of pump-ejector systems for injecting APG together with water into the reservoir when implementing simultaneous water and gas injection (SWAG) in order to increase oil sweeping. However, the problem of increasing the pressure developed by the pump-ejector system is currently insufficiently studied issue. This paper presents an improved layout of the pump-ejector system, recommendations for the optimal composition of the working fluid, as well as the calculation of the system for the conditions of one of the fields in the Ural-Volga region.

Published: March 2021

Abstract
The Western Ciscaucasia, which occupies the flat part of the Krasnodar Territory, is a unique natural site of the Southern Federal District of the Russian Federation. The soil covering of this region is characterized by domination of fertile super-deep and deep Kuban chernozems. However, their intensive use has led to an imbalance between their effective and potential fertility, as evidenced by a decrease in humus reserves and a worsening of its qualitative composition; depletion in nitrogen, phosphorus, potassium, calcium; acidification; heavy metal pollution; and, consequently, an ecological imbalance in the soil–plant system.
Application of an Unmanned Aerial Vehicle for Large-Scale Mapping of Thermokarst Landforms
Authors: Lytkin L V , Syromyatnikov I I 
Published: March 2021

Abstract
thermokarst refers to cryogenic processes, as a result of which characteristic relief forms are formed, as a result of melting of icy frozen soils or an ice complex. The study of the dynamics and distribution of modern thermokarst forms is important from the point of view of using them as one of the main indicators of the degradation of permafrost soils. In recent years, unmanned aerial vehicles, which can create orthorectified images and digital terrain models (DTM) with very high spatial resolution, have been actively used to study thermokarst. This article provides an example of the use of UAVs in the study of the development of thermokarst in s. Uncure. Based on landscape-geomorphological studies and decoding of the created orthophotomap, the areas of thermokarst development were identified. The total land area covered by thermokarst is 0.66 km2, which is 19.5% of the territory of the settlement. According to the classification of P.A. Solovyov, two types of thermokarst relief were distinguished here: bylary and alasy. The largest area is covered by bylars, which are the initial stage of the formation of Alas. They are formed as a result of melting of the upper part of revein ice and form a polygonal-lowland microrelief. More than 6,000 elementary polygons with a total area of 0.4 km2 were discovered here. The landfill area varies from 6 m2 to 223 m2, and the average area is 57 m2. They are formed by local areas throughout the area of the village.

Published: March 2021

Abstract
Sustainable development of rural territories in the conditions of territorial-production localization: methodological aspect. The issues of sustainable development of territories are given great attention. However, in most of the works, general statements of problems, concepts and principles prevail: an analysis of the sustainable development of territories, a comparative analysis of the development of various socio-economic systems in the regions and other general problems of the country’s social and economic development. The insufficient depth of elaboration of conceptual provisions limits the practical value based on the recommendations existing in theories, aimed mainly at the sphere of macroeconomic regulation. This makes it necessary to further study the issues of sustainable development of rural territories. One of the promising areas is production and territorial localization. The local market is a market of a municipality of a region of the Russian Federation or part thereof, representing an economic system based on the principles of limited resources, characterized by the predominance of locally produced goods, unified logistics and a zone of price influence. Development is a process of qualitative and quantitative changes that enhance and improve the current state of the system, i.e. the process of transition from the old, simple to the new, more complex, higher, quantitative and qualitative state of the system. The concept of "development" is closely related to "management." When these concepts are correlated, the relation of the part to the whole is traced. The assessment of the level of development and location of local markets in rural areas was carried out on the basis of the adjusted XYZ analysis, which allowed us to predict development prospects.
