Published: February 2022

Abstract
The introduction of digital technologies in the context of limited investment resources in agriculture requires an informed choice of specific goods and services in a complex saturated market. Traditional methods of expert assessments often lead to inconsistency of expert opinions and difficulty in making decisions. Therefore, the purpose of the article is to develop and test a methodology for choosing digital technologies for agriculture (using the example of software for performing cadastral works). To achieve the goal, the methodology of quadratic penalties was used. At the first stage of the study, the most important criteria for evaluating software were selected (performance, analytical capabilities, taking into account Russian legislation). These are functions that are not obvious to a non-professional buyer, which significantly affect the efficiency of cadastral work on agricultural land. At the second stage of the study, several variants of the programs were directly evaluated and the most effective ones were selected (with a minimum square-law penalty). Their use will allow not only drawing up documents for cadastral registration, but also to determine the exact boundaries of the fields for fair taxation, work planning. The research results can be used to substantiate decisions on the choice of certain digital technologies by agricultural enterprises.

Abstract
At present, in the production of crop products, traditional energy-intensive (classical) methods of soil cultivation are used - plowing, disking, cultivation. At the time of the start of the development of this project, two patents were obtained: No. 2671480 dated October 31, 2018 and No. 2732021 dated September 10, 2020 on the technology of deep pin tillage. In the first version, the technology is implemented using a metal drum with a diameter of 2.5 and more meters with pins 25 or more centimeters long installed on its surface. A drum made on the principle of a wide bicycle wheel from 3 meters or more, is fixed by an axle on the frame, which clings to the tractor. The drum, rolling over the soil, under the action of its own weight under the action of the rotating spokes of the drum, which are endlessly rotating Archimedes levers, loosens spoilage with pins fixed on the outer surface of the drum. The larger the diameter of the drum and, accordingly, the spokes, the lower the energy consumption for loosening the soil and the greater the non-technological mass of such a unit. As a result of the continuation of the study of scientifically grounded ecological-geographical location and more efficient production of spring wheat in the forest-steppe conditions, to explain the possibilities of increasing yields up to 56 kg/ha.

Abstract
Karaganda region is located on the most elevated central part of the Kazakh Upland -Saryarka. This region is a peculiar and geomorphologically heterogeneous, sharply elevated natural country. The paper considers the natural conditions of the Karaganda region and thematic factors of the physical-geographical, geological, engineering geological, ecological-geological directions of research, for the preparation of the foundations for the compilation of an engineering-geodynamic map for the assessment and typification of geo-risks, as well as their geonomization. A series of methodological requirements have been developed as monitoring criteria for a comprehensive assessment of hazards, risks and vulnerability of the population and the territory to the processes of long-term mining by open-cut and underground coal mines in the study area. Of all the geological structures, the most thoroughly studied is the Karaganda synclinorium, elongated in the sublatitudinal direction. The middle part of the synclinorium is occupied by a coal basin. A geological and ecological basis for compiling a new engineering-geological and ecological-geological map for assessing and typing geo-risks is presented, which takes into account coal-bearing formations, coal grades, mining areas and geo-risks manifested in 2020. Data have been developed for the certification of geo-risks of various types that appear as a result of the continuation of the development of a coal deposit in order to minimize their negative impact.

Abstract
The main optimal directions of research work related to the control and regulation of the development process in relation to the Khankalskoye field, while ensuring fire and environmental safety, are identified. The study of reservoir and filtration properties of the reservoir layers is usually carried out by hydrodynamic studies of wells, by methods of steady-state sampling and unsteady processes for restoring bottom-hole pressure in wells. Graphical dependencies are obtained that allow us to study and analyze changes in individual indicators during the development of the deposit and their mutual relations, thanks to which, it is possible to correctly assess the state of development and find the right ways to regulate the processes in terms of ecology and fire hazard. The article presents research on the wells of the Khankalskoye field. The analysis of the control of indicators revealed a number of reasons that influenced the failure to meet the project indicators for oil production.

Abstract
When studying the process of formation of soot nuclei in a flame, it is necessary to pay attention to the sequence of chemical transformations of fuel molecules in order to determine the concentration of dangerous toxic components in the exhaust gases (EG) of a diesel internal combustion engine (DICE). Today, numerous studies are being conducted to establish a detailed kinetic mechanism of the process of carbon condensation and gasification in a DICE. Despite significant progress in understanding the essence and some regularities of the processes occurring in a DICE, it is not yet possible to compile a numerical model that can predict the main indicators of soot content. A semi-empirical mathematical model of soot formation and burnout in a DICE is presented, compiled on the basis of a kinetic model that reliably predicts the dynamics of soot content in the cylinder and the concentration of soot in the EG in a wide range of operating modes of a DICE. The model makes it possible to facilitate the process of studying the factors of soot formation and reduce the cost of conducting experimental studies related to the search for alternative fuels and improving the design of a DICE, optimizing the operation of fuel supply and gas distribution systems.

Abstract
The process of cleaning and diagnostics of pipelines with high flow rates of the pumped product causes some difficulties due to the uncontrolled increase in the speed of the in-line device, and as a result, such sharp changes in speed lead to the loss of diagnostic data in many sections of the pipeline, cleaning is performed with less efficiency. This article discusses in detail the problems of operating pipelines with high flow rates of the pumped product and the main solutions. The problems of uneven movement of in-line devices in pipelines with high flow rates are considered in more detail. Special attention is paid to the problems of experience in the operation and use of in-line diagnostic devices in Russia and abroad. The process of cleaning and diagnostics of pipelines with high flow rates of the pumped product causes some difficulties due to the uncontrolled increase in the speed of the in-line device, and as a result, such sharp changes in speed lead to the loss of diagnostic data in many sections of the pipeline, cleaning is performed with less efficiency. Possible solutions to these problems are described in detail, such as: the correct choice of the in-line device used, bypassing part of the pumped product through bypass holes, reducing the volume of pumping of the transported product during cleaning and in-line diagnostics, creating back pressure at the end of the pipeline.

Development of a packer with an activation tool for the liner extension hanger in the interval of a horizontal open well
Authors: Kopeikin I S 
Published: February 2022

Abstract
Hydraulic fracturing is one of the main methods for stimulating production and putting into development non-drained hydrocarbon reserves. Its natural development is the use of hydraulic fracturing in the horizontal interval of an open hole using several ports, isolated from each other by special elastomers. One of the main and important elements in multiport hydraulic fracturing technologies is a liner hanger packer in an open interval of a horizontal well. Depending on the technology used in multiport hydraulic fracturing, a large number of liner hangers of different types are distinguished. This article discusses the design and principle of operation of a packer for suspending a non-cemented liner of a multiport hydraulic fracturing assembly in an open interval of a horizontal well, as well as the design of a hydraulic activation tool for the above packer. The technical system, consisting of a packer and a hydraulic activation tool to it, makes it possible to install a multiport hydraulic fracturing liner in the well with subsequent disconnection of the drill pipes and their extraction from the well together with the hydraulic activation tool. In addition, the design of the packer allows the connection of production tubing to perform hydraulic fracturing technology in the horizontal section of the open hole. The design of the hydraulic activation tool allows it to be reused after being pulled out of the well when running other liners of multiport hydraulic fracturing.
The potential of digital economy framework to tackle sustainability challenges in urban area
Authors: Polevoi D V , Mamai I B 
Published: February 2022

Abstract
Natural systems and techno-systems form ecosystems of urban areas that are holistic and ordered in time and space. In the context of digitalization, the assessment of the quality of the urban environment necessitates a system analysis, which will make it possible to trace the changes in each factor of anthropogenic load, and to determine the dynamics, patterns and vectors of these changes. The existing approaches to the analysis of the urban environment have a low classification accuracy due to the a priori fuzzy partitioning of the space of anthropogenic load signs. Mathematical and software support for an intelligent system for determining anthropogenic load in the digital economy based on methods of evolutionary calculations and pattern recognition has been developed.

Authors: Gerasimova O A , Vais A A , Luzina E F , Melnik A I , Mantulina A V 
Published: February 2022

Abstract
At present, observations on permanent test plots are insufficient, and they are of a local nature. All this, of course, introduces an additional factor of uncertainty in the assessment of the organic carbon budget. The purpose of the publication is to estimate the age fluxes of organic carbon in pine stands for the 70th period using the example of a local object. The data of the current increase in carbon indicate the presence of two periods in high-density pine forests (25-42 years and 51-58 years), when the forest stands, for a short time, from the objects of “sink” of carbon become its “source”. As a result, it can be stated that timely forestry activities (thinning) will prevent the process of carbon release and promote the intensification of the “runoff” process by increasing the growth of phytomass.

Published: February 2022

Abstract
This paper substantiates the relevance of a study to assess environmental pollution with specific pollutants. It has been established that wastewater treatment plants, which play a key role in the protection of natural water bodies, are “hot spots” for the spread of a new type of environmental pollution - antibiotic. The main ways of getting antibiotics into the aquatic environment are shown, as well as the methods used to detect them. Based on the analysis of the results of studies on the detection of antibiotics in waste waters of different countries, the groups of the most common antibiotics have been identified and the limits of their detection have been established. It is concluded that such studies are necessary not only in large cities, but also in small ones, equipped with a centralized wastewater disposal system, in order to reduce the negative impact on the environment.

Published: February 2022

AbstractNowadays, there is a lack of information on organic carbon stocks in forest stands of various ages. To assess the biological productivity, sketches of growth tables (GT) of various types (“normal”, “modal”, “typological”) were used, drawn up in relation to the pine forests of Karaulny forestry of the educational and experimental forestry enterprise of Reshetnev Siberian State University of Science and Technology. The research area is located in the suburban area of Krasnoyarsk. Depending on the forest density, quality of growing conditions and age, pine forests accumulate different amount of carbon. For a base age of 70 years, normal pine forests (with a density of 1.0 and more) produce 2.22 times more carbon than modal pine forests of growth class III, 2.87 times more than pine forests of growth class IV and 1.99 times more than modal stands of the prevailing forest type.

Published: February 2022

Abstract
Development of technologies for fabricating environmentally friendly fertilizers from organic wastes is an important factor for establishing environmentally friendly zero-waste production, including agriculture. Implementation of this approach entails problems associated with the treatment of byproducts of such processes. In the present study, the technology of physicochemical purification of gases produced by human waste processing was tested on lettuce plants. It has been shown experimentally that the proposed method of deep purification is able to reduce the inhibitory effect of gas on plants. The results can be used to develop agricultural technologies, closed-loop production technologies in other fields, and scientific principles for constructing life support systems intended for space missions.
