Published: February 2022

Abstract
The article considers the problem of creating standardized lighting in sports facilities (gym halls). The article assesses the impact made by the reflection coefficients of the surfaces in the room, the chromaticity of the lamp radiation, and the distribution of light from lighting fixtures on the qualitative and quantitative indicators of lighting. The authors have carried out studies of the actual lighting in the premises intended for sports events, as a result of which it has been established that the lighting of sports facilities is an important and difficult task that helps both athletes achieve the desired results and fans who watch spectacular competitions in the stands and on television. Not only the comfort and convenience of athletes, but also the general safety of the participants in the competition, judges and spectators depends on how well the lighting of the stadiums is organized. Correctly selected stadium lighting fixtures play an important role in the presentation of spectacular events, and poor-quality lighting can even affect the course of the game. Therefore, the purpose of this work is to study the impact of the light environment on the health of athletes, in particular, at sports facilities of a higher educational institution. In the course of work, the authors determined the ways of solving the problem. Based on the study of the actual illumination of the playing hall and according to the calculated indicators, we were able to give recommendations for the modernization of the artificial lighting system, namely the use of 36 LED floodlights of the Feron LL-925 2835 SMD 250W 6400K IP65 AC220V/50Hz type. The required power of the developed artificial lighting system will be 9 kW and the purchase of lamps will cost about 350 thousand rubles.

Abstract
Recently, the use of various information data has significantly increased the growth of cities. Previously, the development of projects for the sustainable development of urban road transport infrastructure lasted for many years, but today most urban road transport problems are solved in a short time, due to intelligent transport systems (ITS). ITS is a “smart” innovative system, the main goal of which is to optimize the safe movement of transport. In this article, the authors present the analytical review and propose effective directions for solving the road transport problem by including an element of reverse traffic in the “Smart City” program to improve the efficiency of the road network and sustainable development of the road transport infrastructure of the city of Volgograd.
Fluorocarbon Production Residue in Composite Coating Used for Protecting Heat-and-Power Equipment from Damage
Authors: Fux S L , Devyaterikova S V 
Published: February 2022

Abstract
Most often breakage in heat-and-power facilities is caused by decomposition of heating elements while in process. The reason of it is a thick layer of boiler scale on their surface caused by hardness salts and ferric carbonates in industrial water, as well as by roughness of the surface of the heater. The quality of the surface is improved by polishing and covering it with a layer of nickel. The above-mentioned processes could be replaced by covering the surface with a composite electrochemical coating (CEC nickel-fluorocarbon) using fluorocarbon production residue which contains a mixture of fluorocarbon and carbon black. Estimate of the parameters of the process of getting CEC nickel-CFx showed that nickel current output does not depend on presence of a dispersion phase (CFx) in conditions of high current density. Throwing power is even, so that it is possible to get uniform nickel coatings and CEC nickel-CFx. It was stated that the physical characteristics, as well as anti-scaling and anti-corrosion characteristics of CEC nickel-CFx are higher than those of nickel coating. CEC nickel-CFx is recommended for using in heat-and-power equipment.
Research of the Dependence of the Pipeline Ends Displacement Value When Cutting Out Its Defective Section on the Elastic Stresses in the Pipe Body
Authors: Shammazov I A , Sidorkin D I , Dzhemilev E R 
Published: February 2022

Abstract
In the process of repairing main oil and gas pipelines with cutting out defective sections, due to the elastic stresses in the body of the pipeline at the end of the first cut, there is a sharp displacement of the pipeline ends on both sides of the cutting site. This sharp displacement poses a threat to the lives of workers, and also complicates the further process of welding a new section of the pipeline due to the need to center its ends relative to each other. At the same time, to reduce the displacement of the ends of the pipeline, it is often pressed down with an excavator bucket before cutting, which contradicts the safety rules for conducting repair work. This article examines the dependence of the displacement value of the ends of the pipeline on the existing elastic stresses in it in order to substantiate the need to take into account the elastic stresses in the body of the pipeline in the used repair methods, as well as the need to develop safe and technologically efficient equipment for fixing the position of the pipeline before cutting and further centering its ends relative to each other.

Published: February 2022

Abstract
In the modern world, industrial development often negatively affects the environment, including the state of water bodies. Pollution of various types, from thermal to chemical (oil spills, industrial waste dumping and thermometric disturbances), have a detrimental effect on flora and fauna. Continuous monitoring of water areas allows timely detection of pollution. One of the tasks of analyzing the state of water resources is monitoring the water surface and monitoring the coastal zone. The aim of the study is to compare classical approaches based on the application of spectral characteristics and machine learning methods to the analysis of the state of water bodies. The studies show the disadvantages of classical methods of remote sensing in solving problems of autonomous monitoring, consisting in poor resistance to noise and the need for constant expert assessment. The paper presents solutions to the problem of detecting pollution of water bodies using machine learning methods.

Authors: Grishaeva Yu M , Spirin I V , Kiseleva S P , Napolov O B , Matantseva O Yu 
Published: February 2022

Abstract
The article discusses the main directions of improving the management of municipal solid waste in accordance with the requirements of the concept of sustainable development. The concept of “solid municipal waste “is analyzed in its comparison with the concept of “solid household waste”. The problems associated with the functioning of the sphere of solid municipal waste management are emphasized. The tasks of the development of this industry for Russia in the near future are defined. Environmental control of MSW is difficult, since the main sources of MSW are households and organizations of municipal services of settlements. These sources are numerous, highly dispersed (scattered throughout the territory). Insufficient eco-cultural training and inadequate self-awareness of the population prevent the regulation of MSW flows and the spread of SD in everyday life. Therefore, the solution to the problem of solid waste should use an adequate methodology, including administrative regulation and systematic improvement of the level of ecological culture of the population.

Authors: Kerimov V Yu , Lavrenova E A , Guryanov S A 
Published: February 2022

Abstract
The results of studying the hydrocarbon systems with application of the modelling techniques using the Schlumberger PetroMod software complexes are considered. Modeling of sedimentary basins of the Bering Sea and their hydrocarbon systems is performed. Estimation of the probability of discovery of oil and gas accumulations related to the marine hydrocarbon systems showed that the highest probabilities of the discovery characterize the GAHS correspondent to the Eocene-Miocene (Mainitsky-Sobolkov) sediments. Probabilities of discovery of the deposits within the younger Gagarin-Avtatkul hydrocarbon systems (Lower to Middle Miocene) are substantially lower. The perspectives of discovery of oil and gas accumulations are related to oil and gas generation and accumulation capacities of insufficiently studied and distributed along the area of the deep-water region Cretaceous-Cenozoic or more ancient sloping deep sea sedimentary complexes, total capacity of which is higher in the northern and eastern near-slope zones of the Aleutian basin comprising 6 to 8 km or more. Studying of the above complexes would apparently facilitate a substantial increase of total hydrocarbon potential of the Bering Sea.

Authors: Musina D R , Yangirov A V , Kharitonov S V 
Published: February 2022

Abstract
In this article, the authors suggest complementing the strategical management methods for the agricultural sector of the region with cognitive modeling technologies. In particular, they developed an integrated cognitive management model comprising two identifying models: the cognitive model of the research subject (the regional agricultural sector) and the cognitive model of the environment (the static model of the region’s agricultural sector), as well as the dynamic cognitive model that allows for the modeling of controlling actions in the sector and assess the results of management decisions. The practical significance of the research lies in the formalization of the management decision-making to implement the model when creating a digital twin of the industry on the digital communications platform for the region’s agricultural sector. The model is versatile because it can be used to model strategic control actions in any of the regions of Russia. One of the drawbacks of this model is the use of the expert approach because of its subjectivity.

Published: February 2022

Abstract
Currently, to determine the productive characteristics and diagnose the state of the bottomhole zone of wells (BHZ) operating the gas condensate deposits of the Beregovoye field, studies are being carried out, which include a set of interrelated methods that differ in theoretical basis, technology and execution technique. The purpose of these studies is to obtain information on the thermobaric parameters of the formation fluid in the reservoir, on the productive characteristics of wells, on the filtration-volumetric and mechanical properties of the porous medium. In this case, the curve of the derivative of the pressure drop at the bottom of the well with respect to the logarithm of time, built in two logarithmic axes, is widely used. To construct this diagnostic curve, three types of data are used: pressure recovery curve (HPC); pressure stabilization curve at constant well flow rate and studies with arbitrary change in flow rate and bottomhole pressure. Using the curve of the derivative of the pressure drop over the logarithm of time, a very wide range of possible structure of the wellbore area, the shape of its drainage boundaries, fractures, double media, etc., is diagnosed. When determining the productive characteristics during the development of the reservoir, the nature of the pressure change over the reservoir area was studied. The frequency of measurement of reservoir pressure by wells was established taking into account the geological features of the Beregovoye field and the rate of formation gas withdrawal from the reservoir.

Abstract
An attempt is made to explain the features of the distribution of deposits and zones of improved reservoirs in the carbonate part of the Vendian-Cambrian oil and gas complex. The conditions of oil and gas content of the carbonate part of the section of the Nepsko-Botuobinskaya anteclise (NBA) are proposed: the formation of a fault zone with feathering cracks → circulation of aggressive solutions along them with the formation of secondary fractured-cavernous reservoirs → vertical migration and accumulation of hydrocarbons in the formed secondary reservoir. According to the presented scheme for the formation of zones of improved reservoirs, promising zones and subsoil areas within Western Yakutia are indicated.

Published: February 2022

Abstract
The article considers an algorithm for estimating the moments of correction of the list of controlled and measured parameters, selecting control points and correcting an individual model of a geotechnical object. As a criterion for correcting the list of parameters, it is proposed to use the moments when the values of the controlled parameters approach the critical zone. The choice of parameters for measurement is carried out on the basis of optimization of the ratio of the cost of monitoring to possible damage. The definition of key control zones is carried out according to the criterion of sensitivity of monitoring zones to changes in external parameters. The practical verification was carried out on the data of geotechnical monitoring of a three-storey building in which destructive processes were recorded.

Published: February 2022

Abstract
In conditions of reduced freshwater reserves, the problem of its extraction of transportation and storage requires scientific justification of the relevant technical and technological solutions and the development of technical means. The article offers a mobile drinking water module. The design of the module provides for its placement in a thermally insulated container including a system of heating, power supply, distribution, filling and disinfection of water. For the development of the drinking water module, modern technical solutions are used to reduce the heat loss of the tank due to the use of a composite material and a cable of electric heater system. Reduction of microorganism propagation activity in water is provided by ultraviolet treatment and disinfection through ultraviolet gate. The design of the container is designed taking into account the possibility of its transportation in all modes of transport as a separate cargo unit. With the device of belts for loading and unloading. For loading into cars without the use of crane equipment, extendable outriggers are installed in the container, which can be used to install the container on water distribution sites. Mobility of the drinking module is ensured by the inclusion of a diesel generator unit in its composition. The tank of the module is made of stainless steel ensuring the safety of water without the formation of harmful impurities in it, and the coating of the tank with a composite material creates the effect of a thermos. The function of filling and distributing water from the tank is implemented using a distribution column with a vortex pump of a system of shut-off valves and hoses for supplying water. Experimental studies of mobile module operation have been performed. It was established that in order to maintain the water temperature in the tank at 10 ° C at an ambient temperature of minus 30 ° C, the heating system should not be switched on. The innovative design of the heat insulated layer reduces the thermal conductivity of similar water storage tanks made of traditional materials by 4 times. The proposed design of the mobile drinking module provides the possibility of creating clean water reserves for catering and household supplies.

Published: February 2022

Abstract
To improve the efficiency of the main petroleum pipeline operation and planning of operating modes when using the method of changing the rotor speed, it is necessary to carefully evaluate and predict the efficiency of pumps depending on the rotor speed. Therefore, experimental research of the dependence of efficiency on the rotor speed is needed. Various modes were considered: from the current frequency of 50 Hz to 25 Hz. The results of the study show us that with a decrease of the rotor speed, there is also a decrease in efficiency, which is opposed to the theory of similarity. The obtained results indicate that during the operation and planning of work, it is necessary to take into account the efficiency of the pumps for the correct forecasting of energy costs.

Published: February 2022

Abstract
The paper shows the relevance of the mechanical properties control of the metal of pipes and welded joints when estimating the safety of pipelines based on the results of periodic inspections. Old pipelines remain in operation in the system, but the issues of aging and degradation of the metal of the pipe and there welded joints remain without proper attention. By aging of a metal, the authors mean a gradual transition to a more stable energy state. How quickly change occurs depends on many factors. Thus, the very mode of operation of the main oil and gas pipelines contributes to the aging of the pipe metal. In addition to strain aging, there are other mechanisms for changing the mechanical properties of pipelines, for example, stress corrosion. Currently, half of all destruction on main gas pipelines occurs due to stress corrosion, the article shows the mechanism of stress corrosion. The paper contains an analysis of the aging and degradation mechanisms of pipe metal. Moreover, not only directions of development of metal control methods are shown but also have taken close look into aging and degradation during the long-term operation of pipelines.

Published: February 2022

Abstract
One of the ways to solve the problem of technogenic pollution is to implement biotechnologies for agricultural lands. The study aims to assess the efficiency of microbiological preparations in the cultivation of potatoes near metallurgical plants in the south of Eastern Siberia. The research was conducted in 2015-2016 on three plots located near Shelekhov aluminum production plant. The Japanese preparation EM and the Russian microbial preparations Baikal EM1 and Fitosporin-M were used. The effect of biological products on plant protection from fungal diseases was observed only in 2015. The two-year application of Fitosporin-M increased the potato yield (by 13-22%) on cultivated alkaline soils; on weakly acidic soils, an increase in the yield (by 26%) was observed only in 2016. When applying EM preparations, a stable increase in the yield (14-22%) was observed on weakly acidic soils; on alkaline soils, an increase in the yield was observed in less than 50% of cases. In general, the stable yield enhancement was observed when applying Fitosporin-M on the alkaline soils. The effectiveness of the EM preparations depended on the agrophone and weather conditions.

Published: February 2022

Abstract
Developing multi-purpose AUV with through-body thrusters capable of undertaking both survey-style missions and low-speed interaction requires sophisticated thruster allocation algorithms. The paper presents the adaptive optimal allocation method. This method allows a smooth transition between different motion styles by exponentially decreasing through-body thrusters’ involvement according to their hydrodynamic model. The proposed method is compared with the prioritized direct allocation method. The simulation result of the control allocation for the AUV “MMT-300” propulsion system model is provided.
