Authors: Sokolskaya Oksana , Gura Dmitry , Gribkova Irina , Belokon Ilya , Turk Gennady
Published: August 2023

The height of buildings and the layout of territories are among the factors influencing various climatic conditions of the city. This area of research is relevant, given the current trend of urbanization of spaces. The conditions formed during the construction and further operation of cities have a significant impact on the condition of a person living in this territory. Also, an important factor is the coverage of the road network. The correctness of the choice of approach to building does not always occur with the accuracy with which it should, which leads to various deviations. There are different types of territory layout: compact, free, group, and mixed. When considering the height of buildings, there are such types as low-rise, medium-rise and high-rise buildings. The city of Krasnodar has historical prerequisites for low-rise buildings, no higher than the crowns of trees. However, with the development of the city, this arrangement of the territory changed to a high-rise one, which affected various living conditions of people. The type of building and the roadbed also affect the temperature regime of the city, as a result of which various deviations from the norms may occur. In the city of Krasnodar, various thermal anomalies are observed due to the heterogeneity of the building. When studying the city's territories and temperature data, various deviations are traced, thanks to which it is clear that in areas with low buildings the temperature is more comfortable for a person, which cannot be said about other areas where taller buildings prevail. It has been established that when studying biospheric conditions on the territory of the city of Krasnodar, the most suitable type of layout is free, and low-rise buildings have a more positive effect on the climate than other types.

Published: August 2023

The article presents the problem of constructing the “city” concept at the current level of urban studies development. The authors proceed from the position that the existing approaches to the analyzed phenomenon do not allow to formulate a concept that can cover various types of socio-territorial organization of people’s lives, referred to as the word “city”. Various researchers offer different grounds for constructing the desired definition: production-economic, territorial, cultural, etc. The authors believe that the definitions used in science are outdated, and the content of the “city” concept requires revision. The article does not claim to be an exhaustive solution to the problem, but rather accentuates the spatial and temporal lines of analysis of the city phenomenon.

Published: August 2023

Resource conservation of water in certain regions of the country is directly related with the use of water and human activity. The unsatisfactory condition of sewage treatment plants, distribution networks and the shortage of capacities of water treatment facilities for environmental management have led to negative environmental consequences. To solve this problem, a technology of ozone-sorption water purification with a remote filtration module has been proposed. A water purification device has been developed in which water is being ozonized and solid precipitation being formed during ozonation is then purified by the usage of special filters. The ozonation process is multifactorial, its implementation is being accompanied by the oxidation of metal cations, as well as organic compounds that are being removed from the water during subsequent filtration. For this purpose, a remote filter filled with activated carbon has been being used, as well as a self-cleaning filter, which uses fundamentally new filters made of porous polymers with filtration, adsorption properties and the ability to self-regenerate. In addition, water disinfection has been provided. When using a filtration module in installations for ozone-sorption water purification, the performance of which corresponds to the performance of the installation, the quality of purified water from consumers is guaranteed.

Published: August 2023

This article discusses related aspects of the formation and provision of the functional quality of the load-bearing elements of frame systems. The subject of the study is the analysis of the state of steel structures with the possible manifestation of violations of the shape of structural elements in flanged joints. The formation and provision of the functional qualities of metal structures and their connections is carried out at all main stages of the life cycle. The scientific hypothesis consists in the assumption that the analysis of the parameters of the stress-strain state in metal structures, characterized by the presence of deviations from the established indicators of functional quality, contributes to an accurate assessment of the parameters of the state and service life. The conditions and circumstances characterizing the possibility of loss of functional qualities of flanged joints of steel structures are determined. A block diagram of the analysis of risks associated with manifestations of the shrinkage distortion of flanges, which reduce the operational reliability of steel structures, has been developed. It is advisable to supplement the methodological basis for the development of design solutions for steel structure units with a forecast (modeling) of the state and operational suitability of a flange connection in the presence of shrinkage distortion of flanges. The results of the analysis of possible states of loss of bearing capacity using a predictive model will contribute to the development of rational parameters of labor intensity and material consumption of manufacturing flanges of steel structures.

Authors: Dmitrienko V.A. , Maslennikov S.A. , Puchkina V.V. , Merenkova N.V.
Published: August 2023

The aim of the paper is to determine fine fractions content of mineral particles formed during the production of building materials. The production of concrete and reinforced concrete products is associated with the use of dispersed mineral substances in large quantities as aggregates. This is accompanied by dust emissions and, accordingly, air pollution. The efficiency of aspiration systems at enterprises is low due to the specifics of the location and operation of the equipment complex in space and time. Therefore, an attempt was made to develop a method for separating dust fractions when assessing the working area dustiness in the production of concrete and reinforced concrete products. Since the main method of assessing dust content is gravimetric, it is proposed to isolate the most dangerous dust particles for the human body when taking air samples with blocks by means of three filters from various filter materials. The performed calibration in laboratory conditions and measurements directly at the workplaces of LLC “Monolit-Yug” showed relatively small errors in air sampling and made it possible to estimate the total dust content and the proportion of fine dust fractions. The conducted research will be used for recommendations development to improve the efficiency of aspiration systems.

Authors: Korotkov Alexander , Korotkova Lidia , Vidin Denis
Published: August 2023

Plain bearings are an important part of many large and critical units and assemblies used in the mining industry. They are widely used in power equipment, powerful pumps, compressors, electric motors and internal combustion engines (ICE). Plain bearings usually include an anti-friction bushing, part of the shaft surface (bearing journal) and an oil layer between them. These are complex and critical parts in which dangerous defects may occur and which directly affect the durability, accuracy and reliability of the entire assembly. To ensure high reliability of equipment with plain bearings used in complex equipment, it is necessary to ensure their quality control, as well as a sufficient level of monitoring the technical condition and diagnosing emerging defects. This is one of the main operational tasks that the personnel of the maintenance and diagnostic services of enterprises have to constantly solve. This paper presents a comparative analysis of the quality of plain bearings for internal combustion engines of various manufacturers. The performance properties of bearings are given depending on the composition. The results of chemical analysis of the base, cover and intermediate layers of ICE liners are presented. Comparative characteristics of plain bearings are given in terms of the chemical composition of the layers and their thickness for various manufacturers: Cummins POL (Poland), Cummins CCEC (China), WETZ (Russia). Recommendations are formulated to improve the performance of plain bearings.

Published: August 2023

In all industry sectors and in the automotive industry, in particular, structural materials that undergo various treatment methods are widely used. Various types of plastic deformation are widely used in the manufacture of products and structural elements made of low-carbon sheet steels. The authors studied the effect of the degree of technological deformation on the fatigue process parameters of flat low-carbon steels. It has been established that the preliminary deformation within the uniform limits causes an increase in fatigue resistance. The kinetic diagrams of the fatigue failure are used to estimate the change in durability from the rate of accumulation of fatigue damage at the cyclic deformation stage until the moment of origination and propagation of the fatigue crack. The ratio of the duration of fatigue failure stages of some sheet automotive steels depending on the degree of preliminary strain by stretching at a given amplitude stress of the cycle is revealed.

Published: August 2023

It has been established that the kinetic curves of adhesion (strength increase) are of the sigma type with the displacement period of the second stage relative to the first one. The period of this displacement is determined by starting of a marked metal flow over the micro-protrusion contact sections and its passing on the baton into a harder material under the second kind stresses. Activation of the contact surface of a harder material (corundum) occurs due to a handover of the deformation of the surface layer is plastically deformed micro-protrusions (grains) of the metal due to the effect of the second kind of micro-stresses which were much higher minimum yield strength of a harder material, thereby causing plastic deformation of the latter.

Published: August 2023

The article briefly analyses the explosion and fire hazard properties of coal dust of different dispersions. It is emphasised that many experts working in the field of explosion protection and industrial safety pay insufficient attention to changes in the properties of the dust when reducing its dispersity. It is suggested to develop a new, complex methodology based on the dispersed composition of coal dust. The authors suggest to put methods of special sample preparation and dispersing of samples in two stages as a basis of the complex methodology. To do research with the help of thermal synchronous analysis of the smaller fractions, the authors propose to regrind the coal fraction obtained after the cone crusher in an analytical mill. To exclude adhesion of particles due to the process of static charges accumulation it is suggested to use impactless sieving machine of Retsch company which allows to take out the accumulated charges of static electricity. The coal dust fractions obtained after sieving were sent for granulometric analysis by a dynamic image processing method in CAMSIRE and by an optical microscopic method using a LEICA DM 4000 with image scope colour processing. A simultaneous thermal analysis was performed selectively for fractions smaller than 1000 μm. This was carried out with an STA 449 F3 and NETZSCH Proteus termal analysis application software. The authors consider that the obtained results allow to conclude that it is further expedient to carry out research work in this direction and will make it possible to develop recommendations aimed at prevention of coal dust aerosol explosions.

The last decade of the twentieth century was characterized by a rapid digitalization of all areas of activity from traditional research to the automation of production, trade, commerce, banking, and other activities. The CALS technology has become largely popular in the world, including Russia. Continuous Acquisition and Lifecycle Support (CALS) stands for the continuous information support of supplies and the life cycle of products, or the information support for product life cycle (IPS) The product life cycle comprises a set of processes performed from the identification of needs for specific products to the satisfaction of such needs and the scrapping of the products. The analysis of the household appliance service companies helped identify the key causes of equipment failure, one of which is failure to meet the operating requirements. We also established that servicing household appliances takes too much of the consumers’ time. They have to understand what consumables they need, when and where to buy them, and how to carry out the maintenance (themselves or through an agent). This article presents an instrument for the operation of products and services required by average consumers in their everyday lives. The tool is made up of a database that stores information about the useful life of different products by specific users as well as information about the maintenance, adjustment, and other actions required for the rational operation of the said products. The database will be used by specific vendors who will keep a database of their clients and products. Alternatively, a retail chain may keep a register of its clients and products sold to them and offer household appliance registration and maintenance services. The third option is creating a cloud service to register consumers, vendors, and service agencies.

The actualization of marketing management methods is due to the ongoing policy of import substitution and the promising development of strategic directions of industrial business. The adaptation of "old" business models and the development of new ones requires the formation of a new marketing paradigm. The purpose of this work is to systematize and evaluate traditional approaches to marketing, substantiate the need to build an adaptive marketing system. Based on the concept of strategic marketing and ecosystem approach, the methodological foundations of building an adaptive marketing system are substantiated, its main tasks and planned results are determined.
Methodology for determining the impact level of municipalities' fiscal capacity on AIC sustainability
Authors: Arzumanyan Misak
Published: August 2023

The purpose of the study is to develop a methodology for quantitative evaluation of the degree of correlation between sustainability (values of its indicators and components) of AIC development and budgetary security of municipal districts. The methodology is based on mathematical logic, represents a three-stage analysis, involves comparing the values of budget indicators (in the revenue side - two indicators; in the expenditure side - six indicators) with the values of indicators of four fundamental components of AIC sustainable development (economic (E), social (S), environmental (N), institutional (I) of municipal districts by calculating correlation coefficients, their transformation into an aggregate form, the formation of which is based on the synergy principle. The methodology is designed for researchers, whose interests are connected with solving problems of regulation of socio-economic development at the local level and the level of the subject of the Federation for making managerial decisions. The results of the analysis will serve as reliable information in substantiating the achieved level of development of the local territories of the region, forecasting the values of the components and the level of development of the AIC, based on the planned values of the indicators of budgetary provision.

Published: August 2023

The article analyses the prospects of sociodemographic development in the regions of the Central Black Earth economic region in the context of modern challenges and threats. It is noted that demographic processes today are significantly transformed under the influence of a complex of negative factors, including COVID-19 pandemic, special military operation, digitalization, etc. It is noted that these factors are ambivalent for demographic development (they can become a white swan or a black swan for demography). It is not yet clear how they will affect life expectancy, migration, employment, and employability, and the reproductive attitudes of citizens. Everything depends on how the situation develops and how effective the measures, in particular state and municipal policy in the sphere of demographic development, will be.
On the radiometric resolution of SAR signals

In accordance with the provisions of the theory of statistical decisions, an expression for the error probability of discriminating the intensities of two signals as a function of the radiometric resolution of a synthetic aperture radar is obtained. The result of observing fluctuations at the input of the processing channel over a finite interval is represented by a sequence of complex samples that are the sum of samples of uncorrelated normal noise and signal samples. This sequence is considered as a normal complex random vector with a specified normalized correlation matrix, while the processing algorithm is assumed to be given. The proposed approach is compared with known methods for determining the radiometric resolution: the heuristic method and the differential radio contrast method. The advantages of the proposed method are demonstrated.
