Published: November 2024

Metering fluids is critical in various industries, and researchers have extensively explored factors affecting measurement accuracy. As a result, numerous sensors and methods are developed to precisely measure volume fractions in multi-phase fluids. A significant challenge in multi-phase fluid pipelines is the formation of scale within the pipes. This issue is particularly problematic in the petroleum industry, leading to narrowed internal diameters, corrosion, increased energy consumption, reduced equipment lifespan, and, most crucially, compromised flow measurement accuracy. This paper proposes a non-destructive metering system incorporating an artificial neural network with capacitive and photon attenuation sensors to address this challenge. The system simulates scale thicknesses from 0 mm to 10 mm using COMSOL multiphysics software and calculates counted rays through Beer Lambert equations. The simulation considers a 10% interval of volume variation in each phase, generating 726 data points. The proposed network, with two inputs—measured capacity and counted rays-and three outputs—volume fractions of gas, water, and oil—achieves mean absolute errors of 0.318, 1.531, and 1.614, respectively. These results demonstrate the system’s ability to accurately gauge volume proportions of a three-phase gas-water-oil fluid, regardless of pipeline scale thickness.

U radu je provedena kauzalna analiza učinka ekološki održivih mješavina s cementom na tlačnu čvrstoću betona i smanjenje emisije CO2. Primijenjen je Bayesov model kauzalnosti, skupova stabala odlučivanja i dubokih neuronskih mreža. Model se zasniva na velikom skupu podataka, broj uzoraka n = 1030 i p = 9 varijabli sastava (cement, šljaka, lebdeći pepeo, voda, plastifikator, krupni agregat, sitni agregat, vrijeme i tlačna čvrstoća betona). Model je usmjereni aciklički graf (DAG) određen heurističkim postupkom optimiranja Bayesova informacijskog kriterija (BIC). AI model dobiven strojnim učenjem omogućuje predikciju tlačne čvrstoće betona s prosječnom apsolutnom pogreškom 3 MPa (4,3 %) u odnosu na pogrešku od 10 MPa za višestruki linearni model. Za eliminaciju interferirajućih efekata među varijablama primijenjen je kriterij usmjerenog razdvajanja (d-separacija) za određivanje kauzalnih učinaka pojedinih varijabli na tlačnu čvrstoću betona. Pojedini učinci izraženi su kao srednji efekti učinaka (engl. Average Treatment Effect, ATE). Rezultat kauzalnog učinka vremena pokazuju dvofaznu dinamiku kinetike nultog stupnja. Najveće vrijednosti ATE (MPa/kg m–3) tijekom prve faze procesa pokazuju: krupni agregat 0,53, plastifikator 0,35 i sitni agregat 0,19, dok najveći negativni učinak ima voda −0,3. U drugoj fazi procesa najveći pozitivni ATE od 0,5 pokazuje plastifikator, a najveći negativni je za krupni agregat od −0,23. Zbog kompleksne interakcije varijabli i složene dinamike procesa predložen je genetički algoritam optimiranja sastava smjese. AI model predviđa znatno potencijalno smanjenje emisije CO2 upotrebom lebdećeg pepela i upotrebom zgure.

The purpose of this study was to determine the effects of different types of catalysts – sulphuric acid titanium dioxide, and Amberlite – and to investigate the effect of catalyst loading (0.1 g, 0.5 g, 1.0 g) on the relative conversion to oxirane (RCO %). This study examines the influence of these different catalyst types and their loadings on the epoxidation of palm oil to identify the optimum conditions for the process. The epoxidised palm oil was analysed using RCO % and Fourier transform infrared spectroscopy (FTIR). The results showed that 0.5 g sulphuric acid as a catalyst with a loading of 0.5 g achieved the highest RCO % at 76.16 %. FTIR spectra revealed the presence of an epoxy group at 833.10 cm–1. In conclusion, using 0.5 g of sulphuric acid as the catalyst provides the optimum conditions for the epoxidation process.

Authors:   International Research and Training Center for Information Technologies and Systems of the National Academy of Science and Ministry of Education and Science of Ukraine., HUBSKY O.M.
Published: November 2024

Introduction. In the modern world, software (SW) is updated daily, particularly for ground control stations (GCS) of unmanned aerial vehicles (UAVs). These systems ' user interfaces (UI) ensure operator interaction with the drone, flight control, mission planning, and realtime data acquisition. These interfaces must be functional, convenient, and intuitive, allowing operators to perform their tasks effectively. Examining global experience allows for an evaluation of existing systems and the identification of areas for improvement. Important aspects include creating intuitive UIs to prevent information overload, ensuring situational awareness, adapting to extreme conditions, and integrating with other systems. The use of virtual and augmented reality technologies, as well as artificial intelligence, can enhance the functionality and convenience of GCS. Such analysis will help in creating safe, efficient, and reliable systems for UAV control. The purpose of the paper is to investigate and conduct a comprehensive analysis of existing user interfaces of software for UAV ground control stations, focusing on their functional capabilities and ease of use. Methods. The following methodological tools were used: concepts of intellectualization of information technologies, the theory of intelligent control, the methodology of building autonomous systems, decision-making theory, and artificial intelligence theory. Results. A review of global experience in user interface development was conducted. The UIs of each of the studied software were analyzed, and their functional capabilities were assessed, identifying their strengths and weaknesses. Comparative tables of interface products were compiled based on their functional capabilities and UI usability levels. Generalized recommendations were prepared for creating a unified interface that combines the best features of existing solutions and addresses their shortcomings. Conclusions. The analysis of GCS UI design for UAVs showed that all systems have strengths and weaknesses. The UI of the Mission Planner software has the most extensive capabilities, but it also requires improvement. Future development should add roles for military pilots and operators, develop a more intuitive and user-friendly interface that meets user needs, and simplify SW settings. For working in extreme conditions, the interface needs to be optimized. Enhancements in data visualization will help make information clear and easy to understand, which is critically important in fast-paced and dangerous situations. Keywords: user interface, ground control station, UAV, virtual reality, augmented reality.
Human Cyber Rights in the Context of Technological Singularity
Authors: Kolesnikov Dmitry
Published: November 2024

Introduction: the physical and technological transformations of the modern world are accelerating due to the theory of technological singularity. This phenomenon indicates that the time between fundamental technological discoveries is shortening. In the context of such a dynamic development of technology, the existing law does not always have time to adapt to new challenges, which pushes for the need to revise legal norms and introduce new concepts. The purpose of the work is to explore fundamental issues related to the impact of technological singularity on human rights as well as to propose a new concept – human cyber rights. Methods: the methods of theoretical analysis and comparative jurisprudence were used in the course of the study. The analysis of literary sources on the research topic was carried out, including the works of scientists and jurists dealing with philosophy of law, technology, and human rights. The methods of logical analysis and synthesis were also used to identify the connections between fundamental concepts and develop a new concept. As a result of the study, the main problems associated with the lag of law from technological progress have been identified. The concept of human cyber rights has been proposed, which includes the rights of an individual in the digital space. The need to adapt legal norms to new challenges, such as the rights of scanned persons and ensuring data security in the digital space, has been discussed. The study has confirmed the need to revise the legal norms in the light of technological singularity and proposed a new concept of human cyber rights as a way to adapt law to the challenges of digital transformation. Further research in this area can contribute to the development of more flexible and effective legal mechanisms to ensure the protection of human rights and freedoms in the era of the digital revolution.
The Legal Regime of the Investment Protection and Promotion Agreement
Authors: Zemlyacheva Ekaterina
Published: November 2024

Introduction: the paper deals with a new contractual structure – the investment protection and promotion agreement, which is one of the investment instruments aimed at stimulating interaction between a public legal entity and a private legal entity. According to the author, Investment Protection and Promotion Agreements are part of a group of investment agreements mediating the mechanisms of a public-private partnership. The purpose of the paper is to study the problems related to the concept, legal nature, and content of the investment protection and promotion agreement. The author also examines the place of the agreement under study in the system of investment contracts and the relationship with related concepts and categories, including the issue of applying the provisions of civil legislation to it. Methods: both the general scientific and specific scientific methods of scientific cognition are used, among which one can distinguish systematic, dialectical, structural and functional, etc. The methods of formal legal, comparative law, and legal forecasting allow taking into account the specifics of the legal nature of the concepts under study, comparing homogeneous legal phenomena, and identifying prospects for the development of legal relations in dynamics. Results: an analysis of the new contractual structure on attracting investments – the investment protection and promotion agreement led to the conclusion of the legislative confusion and difficulty in determining its content and legal nature. Conclusions: the author concludes that it is difficult to determine the legal nature of the investment protection and promotion agreement (IPPA) today due to the imperfection of the Federal Law “On the Investment Protection and Promotion in the Russian Federation,” which does not allow to unequivocally answer the question of whether an investment project should be implemented within the framework of the IPPA itself, or whether it is also necessary to conclude an additional agreement. It is claimed that the IPPA is an unnamed agreement that has no analogues in the Russian legislation. It is concluded that the structure of the IPPA includes the implementation of an investment project. According to the author, until clarification is made to the Federal Law “On the Investment Protection and Promotion in the Russian Federation,” the IPPA will not be implemented in practice.

Authors: Demin Alexey
Published: November 2024

Introduction: the scientific paper aims to analyze the conditions for the formation of the statutory concept of the mechanism of the civil regulation of property (civil) turnover relations. The relevance of the topic is related to the specifics of property turnover relations, which determines the individual (for specific participants in legal relations) statutory concept of regulating and the need to determine the conditions for the formation of the statutory concept for regulating relations within the framework of property turnover. Methods: as a part of the study, a comparative law method was used, which made it possible to identify differences in violations when using the image of a citizen; a systematic approach; a formal logical research method. Results: the analysis of the current legislation of the Russian Federation has been carried out, and the conditions associated with the formation of the statutory concept of the mechanism of the civil regulation of relations in the field of property turnover have been determined. Conclusions: it is determined that the basic statutory concept of the civil mechanism is formed taking into account the objectives of the activities of the participants in the turnover and can be supplemented depending on the circumstances. Such a statutory concept legally ensures the satisfaction of private interests. In case of violation of interests, the protective means of the mechanism of the civil regulation are used, which “help” to restore the property status of the injured party.

The work is focused on practical results, namely, the stable and efficient operation of blockchain platforms in the field of copyright. Conclusions: it has been revealed that to fix the rights to objects of property turnover, there are both opportunities and problems of applying machine-readable law at the present stage; electronic signatures, smart contracts, and entering data into registries are used to make transactions.
Amphibolism of Legal Discourse, or the Art of Word Mastery in Professional Legal Activity
Authors: Solovyova Natalia
Published: November 2024

Introduction: the paper discusses the problems and prospects of the study of legal discourse in procedural law. On the one hand, the lack of unity and unambiguity in the definition of legal discourse makes it possible to characterize the situation as amphibolic. On the other hand, there is an awareness that everything new is just well-forgotten old. The development of the problem of language and law began as early as ancient Greek philosophers and lawyers of Ancient Rome, who for the first time drew attention to the fact that the words of the law were not identical with its “power and authority” (vin ac potestatem). Therefore, it would be at least doubtful to talk about the relevance of the problem from a position of novelty today. The art of using the word in professional activity has always been of concern to the legal community. Therefore, the paper attempts to show continuity in the study of the issue and the possibility of enriching developments in this direction, taking into account modern achievements. In this regard, the purpose of the study is to generalize the positions available in various branches of knowledge regarding what is included in the content of legal discourse, as well as to identify the functions and properties of this multidimensional concept. Methods: in the course of the research, the dialectical and general scientific methods of cognition were used – observation, description, and theoretical understanding of the material, systematic interpretation. Among the specific scientific methods of studying the subject of scientific research were the formal legal and generalization methods. Results: it is advisable to abandon the complication of the definition of legal discourse by eliminating the accumulation of various components in its content, devoid of practical content. “Do not multiply entities unnecessarily” – this is how Occam’s principle sounds. The definition of legal discourse through words in law most clearly and fully characterizes the essence of this phenomenon. Conclusions: legal discourse is the art of using the word in the professional activity of a lawyer, human common sense.

Authors: Dubrovina Anastasia
Published: November 2024

Introduction: in the light of modern socio-economic realities, an urgent problem is the effective protection of the property interests and rights of spouses who own a family business. The conclusion of a prenuptial agreement provides spouses who have a family business and are parties to the prenuptial agreement with the opportunity to reduce financial risks and provide themselves with additional legal protection in the event of termination of the marital relationship. The inclusion of legally verified contractual structures in a prenuptial agreement is very effective in preventing future conflicts between spouses who own a joint business. Purpose: to reveal the legal content of the prenuptial agreement concluded between spouses who own a joint business in the system of contractual structures and to develop recommendations for improving the contractual regulation. Objectives: to identify conflicts related to the legal guarantees of respect for mutual interests of spouses who have a family business and are parties to a prenuptial agreement; to identify contractual structures used to minimize conflicts between the subjects of a prenuptial agreement; and to develop a conceptual model for concluding a prenuptial agreement between spouses who own a joint business remotely via the Internet. Methods: the methodological framework for the research is based on the general scientific methods: systematic analysis, abstraction, and the dialectical method, as well as a set of specific scientific methods: structural and functional, formal legal, comparative law, forecasting, and modeling. Results: it is proposed to amend Art. 11 of Federal Law No. 193-FZ dated July 27, 2010, “On an Alternative Dispute Settlement Procedure with the Participation of an Intermediary (Mediation Procedure),” supplementing its paragraph 8; in the context of the effective implementation of the concept of “Electronic State,” the Federal Notary Chamber it is proposed to develop, test, and implement a virtual assistant based on artificial intelligence technologies, which will function not only on the Federal Notary Chamber website but also on the online resources of the notary chambers of the constituent entities of the Russian Federation. Conclusions: it is recommended to normalize the mediation procedure for spouses who have a family business and are parties to a prenuptial agreement through information and communication technologies; as part of the implementation of the concept of “Electronic State,” the Federal Notary Chamber should develop, test, and implement a virtual assistant (“chatbot”) based on artificial intelligence, which will be available not only on the Federal Notary Chamber website but also on the websites of notary chambers of the constituent entities of the Russian Federation, and at the request of users, including spouses who have a joint family business, it will perform an advisory function when drafting a prenuptial agreement.

Criminal Charge: Scientific Discourse and Problems of Legislative Consolidation
Authors: Manova Nina , Ustinov Dmitry
Published: November 2024

Introduction: “free” use of the term criminal charge at the legislative level and in its official interpretation is largely a consequence of the scientific discourse on the essence of criminal charge, the controversy that has been waged for decades in the theory of criminal procedure on problems related to the concept of criminal charge. In the paper, the authors set a goal to consider the admissibility of polysemicity when using the concept of criminal charge, to identify possible aspects of this legal phenomenon that allow us to reveal its essence and the procedure for its implementation in criminal proceedings. Methods: the methodological framework for the research is a set of methods of scientific cognition, such as the methods of information processing and logical analysis, synthesis, induction, deduction, and generalization. Results: the results of the scientific discourse on the essence of the criminal charge presented in the paper make it possible to understand the problems associated with the polysemicity of the legislator’s use of this concept and demonstrate the influence of doctrinal ideas about the essence of legal phenomena on their legislative consolidation. Conclusions: the concept of “criminal charge” is an integral, interrelated system of aspects, the totality of which allows us to fully express its essence. Only consideration of criminal charge as a multidimensional phenomenon and as an integral systemic category that has certain natural properties and allows revealing its essence explains the ambiguity of using this concept in the text of the law.

Authors: Kutuzov Alexey
Published: November 2024

Introduction: the paper analyzes the scientific positions of understanding footprints and evidence processed exclusively in digital form, their nature, and their relationship with generally accepted categories. The current discussion allows for developing a unified approach to understanding the nature of digital footprints and their interpretation in the science of criminalistics, criminal procedure, and other branches of legal science. The study aims to examine the most influential scientific perspectives on comprehending the fundamental nature of digital footprints and evidence, with the goal of subsequently incorporating these understandings into the criminal law sciences and legislation. The author analyzes the controversial issues of the nature of digital footprints and evidence, clarifies some judgments, and identifies potential solutions. Methods: the dialectical, systemic, and logical methods (general scientific) were used in the course of the study. Among the specific scientific research methods, the formal legal and generalization methods prevailed. Results: based on the results of the conducted research, the most general theoretical positions on understanding the essence of trace and evidentiary information in the digital (electronic) environment are highlighted. The information on the main approaches to understanding this category is summarized, and some additions to the domestic legislation are proposed in order to eliminate existing contradictions. Conclusions: the use of data created and processed in electronic form as orienting and evidentiary information is an objective necessity. The available scientific views on the problem under consideration have studied its essence quite comprehensively, operate in various terms, and, in the author’s opinion, require the development of a conceptual construct, including those enshrined in the legislation to optimize criminal proceedings.

This article demonstrates the technical feasibility of replacing natural sand with stone dust in mortar mixtures. Laboratory tests were conducted to characterize sand and stone dust samples, an industrial by-product originating from quarries. Using a 1:8 ratio and a water/cement ratio of 0.5, according to ABNT NBR 13.276, the materials were used for mortar mixtures for bricklaying and coating. Cylindrical specimens were molded and stored in a humid chamber for different curing periods (7, 14, and 28 days). Compression tests and verification of the elastic modulus were conducted following ABNT NBR 7.215 recommendations. Additionally, experimental panels were built and coated with mortar mixtures dosed with sand and stone dust. Tensile strength tests on the coating were conducted on these panels. The results indicated that stone dust can replace natural sand in mortar mixtures for bricklaying and coating. In all curing periods studied, the specimens with stone dust showed performance equivalent to those dosed with natural sand. The elastic modulus also showed statistically similar values in both mixtures. Therefore, using stone dust to replace natural sand offers the construction industry a sustainable alternative, reducing environmental impact by utilizing quarry by-products instead of non-renewable natural materials.

The objective of the research was to apply composting techniques and social technology to treat food waste in a low -income condominium in southern Brazil, with the joint participation of university researchers and residents. The purpose was not only to reduce the environmental impact caused by waste, but also generate organic compounds of environmental and agronomic value. The project started with an observational visit to the condominium to identify appropriate spaces for the execution of the work. Then the researchers promoted the project through posters and direct conversations with the residents. After this interaction, training workshops were held for participating residents, totaling 40 families and 122 people. The workshops addressed topics such as the impacts of food waste, segregation at source, the composting process and social technology. Educational materials were distributed to assist in the learning process, and visual resources, such as workshops and educational videos, were used. Finally, the composting process was implemented. Social technology played a significant role throughout the process. During workshops and interactions with residents, participants became active learning agents, sharing traditional knowledge and integrating them with scientific knowledge. Educational materials have represented an important tool for social technology, providing information in an accessible and motivational way.  The active participation of researchers and residents was also a positive aspect of this investigation, as it strengthened the condominium community, created social bonds and promoted awareness of environmental responsibility.

Published: November 2024

The construction industry is responsible for the intensive consumption of natural resources and the generation of large volumes of construction and demolition waste (CDW), which are often disposed of improperly. This research developed concrete blocks using recycled CDW aggregates, promoting sustainability and circular economy by reusing these materials in urban infrastructure. Waste was collected from a recycling plant over five months, selecting Brita 1, Brita 0, and Pó de Brita to compose the concrete mixes. Particle size distribution, bulk density, and specific gravity tests were performed, and blocks and specimens were molded with 100% replacement of natural aggregates by CDW. The compressive strength tests were carried out at 14 and 28 days, while the abrasion test was performed only at 28 days. X-ray fluorescence (XRF) and Scanning electron microscopy (SEM) were used to characterize the products. The results indicated a compressive strength of 34.3 MPa at 28 days, close to the minimum required by the standard (35 MPa). XRF analysis showed a predominance of SiO₂, CaO, Al₂O₃, Fe₂O₃, MgO, SO₃, and K₂O oxides, all within normative limits. Leaching and solubilization tests, conducted according to NBR 10005 and NBR 10006, classified the waste as non-hazardous and non-inert. This study demonstrates that using CDW in concrete block production is a viable and sustainable alternative, contributing to waste reduction, material reuse, and the development of sustainable urban infrastructure.

Nonetheless, when a significant disparity in degradation data distribution exists between source and target domains, single-source domain TL may lead to misleading or negative transfer. Multisource domain TL partially mitigates these issues but fails to account for substantial discrepancies in feature-label correlations, impairing RUL prediction accuracy. To cope with this problem, we propose a multisource domain unsupervised adaptive learning method powered by a temporal convolutional network. Using a multilinear conditioning strategy, we combine degradation data and subregion labels to construct input characteristics for the domain discriminator. Additionally, we design a feature extractor that produces label-related features invariant across domains, thereby enhancing prediction precision. We evaluate our method using the publicly available C-MAPSS degradation dataset, demonstrating its effectiveness through a case study and ablation experiments.

One of the important factors affecting the technical condition of vehicles is driving style. This paper investigates the extent to which vehicle repair duration depends on different driving styles. Driving style was assessed based on average fuel consumption, which is an indicator of driving behavior. Three distinct driving styles were identified: mild, moderate, and aggressive, each characterized by different levels of average fuel consumption. The analyses were carried out on the basis of actual operating data of vehicles included in the fleet of one of the transport companies operating in the city of Lublin, Poland. The results of the study showed how vehicle repair time can be reduced by changing driving style from aggressive to mild, and can help answer the question of whether it is justified to increase drivers' competence in economical driving in order to improve vehicle reliability.
Reliability and Fire Performance of Built-up (Battened) Cold-formed Steel Columns: Numerical study
Authors: Zhao Yang
Published: November 2024

Cold-formed steel (CFS) columns play a crucial role in modern construction due to their lightweight, prefabricated, and recyclable characteristics, contributing significantly to structural safety and reliability. However, unprotected CFS columns lose their load-bearing capacity within 10-15 minutes under fire conditions. This study reviews recent advancements aimed at improving the fire resistance of CFS columns, focusing on factors such as steel thickness, grade, cross-sectional shape, and fire protection materials. Using ABAQUS software, validated against experimental data, parametric studies reveal that thicker sections and higher-grade steels enhance fire resistance, delaying structural failure. Fire protection strategies, such as plasterboard encasement, further bolster safety. The Complex cross-sectional shape demonstrated the highest load capacity (178.51 kN), while G450 steel outperformed other grades in both load capacity and fire resistance. Columns with 1.95 mm thickness provided the longest failure time (73.49 minutes).

Published: November 2024

The article presents an efficient multithreaded implementation of the modern 3SEQ algorithm for detecting recombinant genetic sequences, tested on viral genomes. The work was carried out within the framework of the project to create a domestic (Russian) web-platform (bioprojects.iis.nsk.su) for solving a wide range of problems related to data analysis in the field of bioinformatics, virology and epidemiology. A recombinant viral genome emerges when two different variants of virus genomes of the same species exchange their parts, which is possible in case of infection with both variants simultaneously. The emergence of recombinants is rare but important events in the context of virus evolution research. One of the most promising among the existing algorithms for searching for recombinants is 3SEQ, but the author's version works only in single-threaded mode. We implemented this algorithm with support for multithreaded computing and taking into account the dates of sample collection, which provided a significant increase in the computing speed. The developed software was used to search for recombinants in the samples of influenza A H1N1 (only PB2 segments from 2174 genomes were analyzed), Dengue fever (726 genomes), Ebola virus (865 genomes) and in two samples of SARS-CoV-2 coronavirus (776 and 2132 genomes). No recombinants were found for influenza A H1N1 (PB2 segment) and the first dataset on SARS-CoV-2 (variant from Russia), which is in agreement with the analysis of the same data by the RDP algorithm. For the second SARS-CoV-2 dataset (variants from the Siberian Federal District), the only recombinant present in the dataset was correctly found. 725 recombinants were found in Dengue fever viruses, with a recombination region length in the range from 50 to 1000 nucleotides. In Ebola viruses, the length of the recombination region was shorter – in 572 recombinants it was in the range of 50 to 100 nucleotides, and in 249 genomes – was less than 50 nucleotides.

Published: November 2024

The article presents a new method for assessing the fire resistance of monolithic girderless non-accumulating floors of buildings and structures. The essence of the method lies in the fact that thermal (fire) tests of the floor are carried out without destruction, according to a set of single indicators of the quality of working fittings and structural concrete of continuous slabs. The use of the method makes it possible to determine the fire resistance of an uncut reinforced concrete slab of a girderless ceiling of a building without full-scale fire exposure, increases the reliability of statistical quality control and non-destructive testing, reduces economic costs.

Authors: Prokopovich Anatoly Аl. , Buzovskaya Yana Al.
Published: November 2024

The article presents the results of experimental studies to assess the strength of reinforced concrete beams with varying degrees of destruction of the protective layer of the working longitudinal reinforcement, followed by its restoration with a repair mixture. The test results of three series of prototypes, three samples in each series, are presented. Within the series, prototypes were made with the same longitudinal reinforcement, and the samples in each series differed in the degree of destruction of the protective layer of the longitudinal working reinforcement in the transverse bending zone. The samples were tested as freely supported beams loaded in the span by two identical concentrated forces. The results obtained made it possible to evaluate the role of longitudinal reinforcement, depending on the degree of destruction of its protective layer, in ensuring strength, forming a stress-strain state and the nature of destruction of reinforced concrete beams of rectangular cross-section in transverse bending zones.

The article is devoted to solving urgent problems of creating and improving closed water management systems of industrial enterprises. An overview and detailed analysis of the implementation of the federal program “Waste” in the existing regional centers of the Russian Federation is provided. During the analysis, the authors identified and solved the following tasks: justification of the need for the creation of closed water management systems (ZSVH); determination of the subject composition required for the development of SPM; selection of process diagrams and corresponding equipment. The article illustrates the experience of implementing the federal program “Waste” in various regions of the Russian Federation, which testifies to the cooperation of enterprises where industrial waste is generated with enterprises where it is processed and used as raw materials or disposed of. Based on the consideration of the types of industrial effluents and the directions of activities of enterprises, the authors came to the conclusion about the advisability of special treatment of industrial effluents before disposal directly at the site of their formation to obtain a dried final product, which should be carried out in accordance with regulatory requirements in the field of waste management.
