Authors: Prisnyi A A
Published: March 2021

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

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.

Authors: Dolobeshkin E V , Gumbarov A D , Bandurin M A
Published: March 2021

The 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

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.

Authors: Nikitina M A
Published: March 2021

To 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

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.

Authors: Mokhirev A P , Medvedev S O , Bragina N A
Published: March 2021

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: Lytkin L V , Syromyatnikov I I
Published: March 2021

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.

Authors: Kovaleva I V , Voronkova O Y , Kucherenko T V
Published: March 2021

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.

Authors: Sablin K , Tripathi Sandeep
Published: March 2021

The paper is devoted to the study of traditional energy projects as an instrument of political influence in the foreign affairs. In the contemporary international politics, the importance of natural and mineral resources is actualized. These resources are not only an item of international trade in the world economy, but also it is a bargaining chip in the political bargaining between states. Approaches to the study of political influence are considered, as well as the role of traditional energy in foreign affairs is revealed. Projects of the largest resource-extraction companies in Russia are highlighted. The authors show that these projects are used by the Russian leadership as an instrument of political influence in various macro-regions of the world. Resource-extraction companies are used as geopolitical instrument to consolidate position of Russia and its allies. At the same time, the problem of searching options for "restructuring" the model of extensive extraction and export of raw materials is especially important on the way of the economy transformation into a model of integrated development. There is the pyramid of enclaves of wealth according to the fact that the Russian economy is developing between the poles of economic fragmentation and political-administrative centralization.

Authors: Zaytseva A I , Sagdeeva L S , Savintseva S A
Published: March 2021

The problem of assessing the innovative potential of the regions is the focus of domestic and foreign scientific research. This topic becomes especially relevant for the so-called resource-type regions, where the dependence of the economy on the industrial sector has traditionally been very high. Since there is no category "resource sector of the economy" in the Russian statistical register, data on the structure of gross value added of the region were used for its allocation. And according to the structure of value added 18 regions were included to the group of resource-type regions. A system of the indicators for the assessment of the innovation potential of the recourse-type regions is suggested in the paper. The integrated indicator over 2017 year has been calculated using the geometric mean and compared with the indicator over 2013 year. The results of the analysis let the authors divide the regions into three groups according to the value of integral indicator of assessing innovative potential and detect the most significant differences and gaps in each group.

Authors: Savelyev M Y , Sokolova N G , Polyakov Y N
Published: March 2021

In order to identify the features of economic development and the historical fate of new industrial countries (NIC), an econometric analysis of their strategies and development dynamics since 1950 was carried out based on the parameters of real GDP growth rates and their standard deviation. 6 types of development were identified. The dynamics of development for 8 economic cycles and paired correlations between countries are estimated. 4 waves of growth rates and 5 waves of MSD were revealed. It is hypothesized that the correlation of growth rates shows the similarity of countries in their use of opportunities, and the correlation of MSD shows that of their responses to threats. Connection graphs are constructed and 3 clusters of countries with similar historical destinies are obtained as a result of the analysis. It is recorded that there are 3 groups of 11 countries with a similar development strategy. The other 10 have no development analogues. Determined: China applies import substitution and export strategies, it can become the leader of the NIC and compete with the global dominance of the OECD countries; the post-industrial development of the NIC cannot be based on a liberal, import-substituting or export strategy. As an alternative, a strategy for improving the living standards is proposed.

The article analyzes the existing forms of cooperation, primarily in the framework of the Northern Dimension Partnership in the field of transport and logistics. The charter document of the Memorandum of Understanding 2009 is considered in more detail. First of all, attention is focused on the compliance of the established international legal norms in the Memorandum with the practical actions undertaken by the participants of the Partnership. The current situation regarding relations between the European Union and the Russian Federation is analyzed through the prism of the political tendencies of our time. The article emphasizes the importance of the research, especially in the field of transport and logistics, as transport is a strategic arsenal of any state. The future economy of the country depends on the development of transport relations with partners. At the beginning of the article, an important issue is studied – cooperation, as a form of interaction between the subjects of international public law. The specificity of cooperation is noted, which consists in the fact that as a form of interaction, it is fixed in several international legal acts and is considered as a generally accepted principle of public international law, and, accordingly, as jus cogens norms. The article also presents an excursion into the history of the origin and further development of relations on the issue of transport and logistics between the European Union and the Russian Federation. The purpose of the research is to identify specific prospects for the future interaction of the Partnership participants, and also, on the basis of the existing information, to suggest areas in which there is need to work with great effort.
Recovering Infrastructure Public-Private Partnership Projects as Effective «Epinomic» Policy in Fighting the COVID-19 Pandemic
Authors: Vaslavskiy Ya I
Published: March 2021

The emergency conditions caused by the coronavirus pandemic in 2020 made the national governments the last resort, which was forced to bear all the financial costs associated with the lockdown in the national economy, with social support of the population and fiscal and monetary help to private firms which business was blocked. Lockdowns, publicly declared in countries around the world to stop the exponential growth of coronavirus-infected patients, have brought unprecedented losses in both human lives and national welfare. As a result, the coronavirus pandemic left two fundamental priorities for the state: (1) to stabilize the epidemiological situation in the country and (2) to reopen the economy in time after the lockdown. On this basis, the term "epinomics" was introduced, which assumes the primary public task to ensure the life and health of citizens, and only under this condition allows the possibility of economic recovery. In this case, the expansion of the practice of implementing public infrastructure projects on the basis of public-private partnership realizes the essence of the state’s epinomic strategy. Moreover, in the post-COVID-19 future, infrastructure projects can become an effective form of implementation of the UN “human-first” model, since they allow solving the immediate problems of ordinary citizens mostly affected in 2020. It is about the growth of employment, the provision of workforce wages, development of socially significant infrastructure, which contribution to the economic revival of countries can hardly be overestimated. At the same time, the government through public-private partnership gets the opportunity to directly broadcast to society the results of the effectiveness of its epinomic strategy in stabilizing the epidemiological situation and reopening the economy after the lockdown.
A Digital Tool for Capacity Load Optimization in Spatially Distributed Production Systems

Published: March 2021

Improving the efficiency of the use of fixed assets is one of the priority tasks facing modern machine-building enterprises. It is particularly relevant for spatially distributed holding structures that have emerged in the process of reforming the domestic machine-building complex and include enterprises that produce similar products and have similar types of production assets.

The purpose of the paper is to develop on the basis of mathematical modeling tools for solving problems of optimization of industrial enterprises’ fixed assets development and use.

An approach to optimize the fixed assets load in a spatially distributed production system is proposed. A mathematical model in the form of a linear programming production and transport optimization problem is formulated, which allows one to find optimal production capacity load modes in a wide range of conditions. The optimal regimes of this model are studied. It is shown that in certain cases the capacity use optimization can be the only way to ensure the timely fulfillment of the customers’ orders

The use of modern digital technologies that provide dynamic forecasting and optimization of the production capacity allows to achieve a number of improvements, including the production time and cost reduction and the growth in efficiently used production means.

Published: March 2021

This paper presents a universal method of structural analysis of the commercial real estate market with a detailed step-by-step analysis. For example, the analysis was carried out based on commercial real estate in the city of Ekaterinburg. The method is unique in creating visual content that is a map of typical territorial zones of the city of Ekaterinburg. The analysis method also includes the classical structuring of information in the form of tables and diagrams based on real offers for the sale and lease of real estate. The authors formulated forecasts for each segment of the commercial real estate market. Based on this work, anyone can conduct a similar analysis in their city or use it as a base for creating a visualization of the territory according to the zoning given in the work. Having information structured in this way will make it easier to evaluate real estate objects by their real environment.
Creative Cards on Chemistry in the Mental Development of Students

The change in the professional positioning of a modern university graduate — from the narrow development of one specialty to the ability to adapt to the changing conditions of the innovation economy; reliance on creativity and mental development of an individual identified the research problem — the lack of methodological support to develop teaching aids at the university. The theory comprehension and practice of the educational process organization in the chemical direction made it possible to affirm that there are large reserves for the students’ mental development due to the completeness and depth, consistency, and logic of a high theoretical level in the chemical disciplines.

The study purpose is to develop and determine the effectiveness of the use of creative cards in the study of chemical disciplines to improve the level of students’ mental development.

The research methodology included an analysis of the essence of the concept «creative card», identification of criteria and indicators of students’ mental development, development of a set of creative cards in chemistry, determination of their influence on the mental development level, development of a methodical system of students’ mental development using creative cards, and testing the effectiveness of the system in a teaching experiment.

The basis of the chosen approach is an idea of cognitive psychology D. P. Ausubel. Presentation of new concepts and judgments through logical structures and concepts are already known; accumulated by students, identifying the main ideas of the subject, further differentiation, detailing; combining new material with previously presented information by comparing, comparing and finding connections between them is one of the effective tools to organize and present knowledge. However, the study made it possible to substantiate creative cards as means of learning that affects mental development. Developed methodological support for the use of creative cards to improve the level of students’ mental development, confirmed its effectiveness.
Development of Dedusting Technology in the Silicon Production

Published: March 2021

The aim of this paper was to identify processes forming the largest amounts of dust and to develop and test additional methods for suppressing dust emissions into the air of the working area for the main occupations, primarily at the stage of loading ore raw materials into the ore-smelting furnace for the silicon production. Using the method for determining the specific surface area of fine materials - the Brunauer-Emmett-Teller (BET) method - it was shown that gas cleaning dust of the silicon production has a developed surface and high wetting ability, which makes it possible to recommend dust suppression methods using irrigation systems. In assessing occupational risks, it has been found that the level of risk is high, working conditions are hazardous and it is necessary to take measures to reduce the dust content in the workplace through the introduction of effective dust suppression systems.
