FEATURES OF THE CSTO FUNCTIONING
Authors:   International University Ala-Too, Bektur uulu Ormon
Published: December 2023

This article describes the process of forming the CSTO organization as part of the creation of a system that will ensure collective security. Both the strengths and weaknesses of the international regional organization are considered. They are determined by the specifics of its structure. Referring to the data of the Russian Institute of Contemporary Development, the author lists the following trends: excessive multifunctionality, lack of unity and internal organizational discipline, search for common goals and values, weak positioning in the system of regional and international security structures, lack of a clear system for resolving conflicts in the post-Soviet space. These factors hinder its effective work and often lead to hostilities between the countries participating in the treaty and other incidents.

Published: December 2023

Sufficient conditions are established for lower bounds and tending to infinity as the argument of solutions to a weakly non-linear second-order Volterra integro-differential equation with delays on the half-axis grows unbounded. For this purpose, a non-standard method of reduction to a system, the method of transforming the equations of V. Volterra, the method of partial cutting, the method of integral inequalities with delays and the method of estimating solutions from below Yu.A. Ved are developed. It is shown that solutions with initial data from a certain manifold have lower bounds, and such solutions tend to infinity according to the exponential law with unlimited growth of the argument. This article proposes a technique for solving the problem of estimating from below on the half-line solutions of a weakly nonlinear Volterra-type integro-differential equation of the second order with delays, while the main role is played by the non-standard method of reduction to the system and the method of estimating solutions from below Yu.A.Ved (1965).

Authors:   International University Ala-Too, Mohammad Imtiyaz Gulbarga , Shaidullaev Nurlan ,   University of Central Asia
Published: December 2023

Memory analysis is essential for spotting malicious programs since it can record a variety of traits and behaviors. The detection rate and sophisticated malware obfuscation are two major challenges in malware detection, even though there has been a lot of research in the area. An effective framework that focuses on identifying obfuscation and hidden malware is desperately needed because advanced malware employs obfuscation and other tactics to avoid detection. The VolMemLyzer has been improved in this study to focus on hidden and obfuscated malware when used with a stacked ensemble machine learning model to build a framework for effectively identifying malware. It is one of the most updated memory feature extractors for learning systems.

Managing training load in rugby union is crucial for optimising performance and injury prevention. Contact training warrants attention because of higher overall injury and head impact risk, yet players must develop physical, technical, and mental skills to withstand the demands of the game. To help coaches manage contact loads in professional rugby, World Rugby and International Rugby Players convened an expert working group. They conducted a global survey with players to develop contact load guidelines. This commentary aims to describe the contact load guidelines and their implementation, and identify areas where future work is needed to support their evolution.
Of Rainbow and Granite: Androgynous Narrative in Virginia Woolf’s Orlando and Ali Smith’s How to Be Both
Authors: De Riso Giuseppe
Published: December 2023

L’articolo si propone di delineare un’analisi comparativa tra Orlando (1928) di Virginia Woolf e How to Be Both (2014) di Ali Smith. In particolare, si intende dimostrare come l’opera di Smith rielabori in modo creativo il romanzo di Woolf, andando così ad incarnare e ad esprimere con vividezza il concetto di ‘mente androgina’ teorizzato dalla stessa autrice. Ciò avviene attraverso la rimozione dei confini temporali tra passato e presente, l’ambiguità sessuale delle protagoniste e, soprattutto, attraverso un paradigma letterario capace di indagare la necessità di un’interazione reciproca tra autrici e lettori, e di un più ampio dialogo tra il testo letterario e le altre influenze artistiche e culturali con le quali instaura un imprescindibile rapporto dialettico.

Unfinished business
Authors: Gribble Jayson , Thyssen Ashwin , Jacobs Dewald
Published: December 2023

In this essay, we seek to relate the prophetic critique of the Belhar Confession to several matters that could be classified as “unfinished business” for the Uniting Reformed Church in Southern Africa (URCSA). In particular, we argue that Belhar – which has been a confessional document of the church since 1986 – speaks to several ongoing issues which impact South Africa and URCSA in particular. For the sake of this essay, we focus specifically on the “unfinished business” of Belhar as it relates to patriarchy, within the context of femicide, the question of the inclusion of queer bodies within the body of URCSA, and the continuing societal problem of xenophobia and Afrophobia in South Africa at large.

Currently, a wide demand for the implementation and use of various cloud solutions is a modern trend and the driving force behind the development of network technologies. The growth of cloud application services delivered through data centers with varying network traffic needs demonstrates the limitations of traditional routing and load balancing methods. The combination of the advantages of software defined networks (SDN) technology and artificial intelligence (AI) methods ensures efficient management and operation of computer network resources. The paper proposes an approach to neural network multipath routing in SDN based on a genetic algorithm. The architecture and model of an artificial neural network has been developed to solve the problem of multipath routing in the SDN, which is able to predict the shortest paths based on the metrics of communication links. To optimize the hyperparameters of the neural network model, it is proposed to use a modified genetic algorithm. A visual software system SDNLoadBalancer has been developed and an experimental SDN topology has been designed, which makes it possible to study in detail the processes of neural network multipath routing in SDN based on the proposed approach. The obtained results show that the proposed neural network model has the ability to predict routes with high accuracy in real time, which makes it possible to implement various load balancing schemes in order to increase performance of SDN.
ASXL1 MUTATION ANALYSIS IN CHRONIC MYELOID LEUKAEMIA PATIENTS
Authors: Hamid Mohammad , Mohammed Aras , Mohamad Dlnya
Published: December 2023

BackgroundIn recent years, additional sex comb-like 1 (ASXL1) gene mutations have recently been linked to several myeloid cancers.
Objectives To characterize ASXL1 mutation prevalence, determine if these abnormalities might constitute a significant event in CML prognosis, and establish the correlations if these mutations are associated with CML transformation and/or imatinib (IM) resistance, Here we designed a study to investigate ASXL1 gene that is frequently mutated in myeloid malignancies and evaluated their occurrence in a well-defined group of CML patients.
Patients and MethodsThe study population consists of 80 patients diagnosed with CML under treatment with TKI (Imatinib 400,600,800 mg/day and Nilotinib). Ten healthy subjects were checked as controls. Depending on their molecular and/or cytogenetic response, CML patients will either be classified into imatinib-resistant or imatinib-good responders. Then the DNA was extracted depending on the Salting-Out protocol. Then genome amplification was performed on exon 12 and in the HOT spot region for the detection of somatic mutations, using conventional PCR.
ResultsNine out of 80 CML samples (11.25%) were determined to have mutations with the ASXL1 gene. We identified a novel Mutation (c.1808_1820delCCTCCTGCCGGGG S603Ffs*96) in one of the patients that has not been reported before. We also identified three other mutations (c.1933_1934del G p.G645Wfs*12, c.2047A>G p.T683A, c.1900_1922 delAGAGAGGCGGCCACCACTGCCAT  E635Rfs*15).
ConclusionOur discovery of an ASXL1 mutation, a potential tumour suppressor gene, is a significant genetic aberration in CML. Our findings suggest that ASXL1 mutations are common in patients with late stages of the disease and imatinib therapy resistance.

Background. Landscaping of urban environments significantly mitigates the negative effects of "urban heat islands", which in turn has a positive effect on many aspects of human life. Therefore, the purpose of our research was to identify droughttolerant rare and decorative species of woody plants with further recommendation for their inclusion in the ecosystems of the urban environment. Methods. For research, we selected from the collections of the Botanical Garden named after acad. O.V. Fomina 25 highly decorative species of trees with a height from 10 to 50 m, which come from temperate and continental climate zones. Among them, 14 species are uncommon and 11 species are widespread in mass culture in the Polissia and Forest-Steppe zone of Ukraine. The drought resistance test was conducted twice: in early June and also in early September. Relative drought resistance was assessed by following parameters: tissue hydration and water loss per unit time. Results. According to the results of the study, most of the 25 species of tall trees showed a high or average level of drought resistance. The most drought-resistant light-loving and shade-tolerant species were recommended. Species that may require additional care during cultivation (Phelodendron amurense and Styphnolobium japonicum) have been identified, which must be taken into account when landscaping urban areas. Conclusions. Among shade-tolerant trees, the following species can be recommended for cultivation in urban conditions as highly drought-resistant: Acer mandshuricum, Acer velutinum, Corylus colurna and Prunus padus. The following light-loving plants turned out to be the most drought-resistant: Liriodendron chinense, Ginkgo biloba, Acer saccharinum, Catalpa bignonioides, Catalpa fargesii and Tilia europea.

Background. Systemic inflammation is recognized a sone of the key features of Alzheimer's disease (AD) – a neurodegenerative disorder, which is characterized by cognitive decline with progressive memory loss and affects millions of predominantlyeld erly people. Recent literature data suggest the involvement of periphera limmune cells in the initiation and progression of AD. However, our understanding of the population composition of peripheral blood leukocytes and its contribution to disease progression remains limited. The use of anima lmodels plays an important role in investigating possible mechanisms linking the periphera limmune system to the inflammatory processes underlying neurode generation. The aim of this study was comparative assessment of the composition of leukocyte subsets in rats with AD, induced by intrahippocampa linjection of amyloidbeta (Aβ) 1–40 and Aβ 25–35. Methods. Male Wistar rats were used in the experiments, including intact and sham-operated animals as controls. Disease development was confirmed b y assessing cognitive impairment in the Barnesmaze be havioral test and by the loss of dopaminergic neurons. Hematological parameters were evaluatedat the end of the experiment (day 37 after the disease initiation), including absolute leukocyte count, as well as absolute and relative count of their main subsets: lymphocytes, monocytes, andneutrophils. Rats with AD induced by Aβ 1–40 exhibited granulocytosis (a fivefold increase in absolute granulocyte countin the circulation). Absolute and relative count of lymphocytes In these animals were decreased on average by 2.5 times, monocyte count – on average by 3 times as compared to those in intactand sham-operated rats.In rats with Αβ 25–35-induced AD, leukocytosis with slightly decreased lymphocyte proportion, increase in monocyte count twice at average and unchanged neutrophil countwere revealed. Results. Therefore, animalswith AD, inducedby Aβ 1–40, had hematologic markers of systemic inflammation (leukocytosis, granulocytosis, lymphocytopenia, andmonocytopenia). Conclusions. These results suggest that the Aβ 1–40-induced AD model more accurately reproduces the hematologic signs of systemic inflammation observed in patients with this pathology.

Published: December 2023

Background. Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) infection was first reported in Wuhan, China in December 2019, and then spread rapidly worldwide, causing an estimated 771 million active cases with ~7 million deaths as of September 2023. The pandemic of the new coronavirus SARS-CoV-2 poses a great threat to the world in many aspects: medical, social, economic and other. A comprehensive understanding of the interaction of the virus with the body is fundamentally important in the fight against SARS-CoV-2. During the 2019 coronavirus disease (Coronavirus disease 2019, COVID-19), epithelial cells of the respiratory tract are affected, which is manifested by symptoms of a respiratory infection. The SARS-CoV-2 virus, as an infectious trigger, causes damage to other organ systems, in particular, the musculoskeletal system, and can also complicate the condition of patients with comorbid diseases. Мethods. The aim of the work was to determine the expression of LRP1 and OLR1 genes in the blood of patients with osteoarthritis after SARS-CoV2 infection. All study participants were divided into three groups. The first group (n = 10) is conditionally healthy people. The second group (n = 22) – patients with osteoarthritis of the knee joints II-III degree. The third group (n = 14) is patients with osteoarthritis of the knee joints II-III degree, who suffered a mild and moderate form of COVID-19 6–9 months ago. The expression of LRP1 and OLR1 genes was determined in the blood. RNA was obtained by the Chomczynski method. Synthesis of cDNA and quantitative polymerase chain reaction in real time (Real-time PCR, qPCR) using the commercial kit "Thermo Scientific Verso SYBR Green 1-Step qRT-PCR ROX Mix" ("Thermo Scientific, Lithuania). Processing of research results was carried out using generally accepted methods of variational statistics. Results. In the blood of patients with osteoarthritis, the expression of the LRP1 gene decreases and the expression of the OLR1 gene increases compared to a group of conditionally healthy people. In patients with osteoarthritis after infection with SARS-CoV-2, more significant violations of the expression of the studied genes are shown. Conclusions. The obtained data indicate a violation of the metabolism of lipoproteins in the body, the activation of free radical processes and the development of systemic inflammation, which leads to a decrease in vascular protection and endothelial dysfunction in patients with osteoarthritis, which increases under conditions of additional infectious load on the body under the influence of SARS-CoV2 infection.

Published: December 2023

This systematic review investigates the current state of research on Generative Artificial Intelligence (GenAI) and its implications for (EMI) Higher Education. The study employs a methodology based on an evidence-informed and theoretically credible framework to answer two research questions: (1) What studies of relevance to (EMI) Higher Education have been published thus far, considering the most recent developments of GenAI? and (2) Which key areas are currently lacking in extant literature and in need of further scholarly exploration in this regard in (EMI) Higher Education research? The results of the study reveal a limited number of pertinent publications, indicating a sparse scholarly landscape with a dearth of work on the implications of Generative AI in EMI Higher Education. Based on these findings, preliminary recommendations have been made to guide future research in this area. This study contributes to the literature by highlighting the need for further research on the potential of GenAI to enhance the teaching and learning experience in (EMI) Higher Education and provides a theoretical framework to guide future research. These findings may inform researchers and educators interested in exploring how GenAI may be leveraged from different educational perspectives.

Authors: Rajeev Neeraja , Al-Fataisi Abdullah M , Kariyattil Rajeev
Published: December 2023

Adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas are known to be associated with behavioural changes but acute presentation including psychosis and delirium are less common. We report the case of a 42-year-old female patient with a known medical history of hypertension and diabetes mellitus, presenting with acute onset behavioural changes suggestive of psychosis to a tertiary care centre in Muscat, Oman in 2022. Further evaluation revealed an ACTH dependent Cushing’s disease with a pituitary microadenoma. The patient was admitted for endoscopic resection of the adenoma. During the peri-operative period, she experienced worsening of psychosis in addition to delirium. She also developed episodes of unresponsiveness, posturing, severe diaphoresis and dyspnoea accompanied by tachycardia and hypertension which were managed with midazolam and levetiracetam. A seizure work-up and computed tomography brain scan were unremarkable. At follow-up, she showed full resolution of symptoms with good blood pressure and glycaemic control.

Authors:   Saratov State University, Lobanov Nikita , Matveev Oleg ,   Saratov State University, Morozova Maria ,   Saratov State University
Published: December 2023

Purpose. The purpose of this paper is to investigate the effect of nonlinearity on formation mechanism and characteristics of Bragg resonances in vertically coupled magnon crystals with periodic groove system on the surface. In this paper a wave model is constructed, a nonlinear dispersion relation for surface magnetostatic waves in such a structure is obtained and the characteristics of each of the Bragg resonances are numerically studied with increasing input signal power. Methods. Theoretical methods of investigation of spin-wave excitations in a wide class of structures with ferromagnetic layers have been used. In particular, the following theoretical models have been used: coupled wave method, long-wave approximation. Results. This paper presents the results of a theoretical investigation of the effect of magnetic nonlinearity on Bragg resonances in a sandwich structure based on magnon crystals with periodic grooves on the surface separated by a dielectric layer. A mechanism for the formation of band gaps at the Bragg resonance frequencies in the presence of media nonlinearity has been revealed. It is shown that with increasing input power the frequency interval between the band gaps decreases. With increasing magnetization difference of magnon crystals, the effect of nonlinear convergence is more pronounced. Conclusion. The identified features extend the capabilities of sandwich structures based on magnon crystals for frequency selective signal processing by controlling the frequency selectivity, both via static coupling parameters, periodicity and layer magnetisation, and dynamically via the input signal power.

Authors: Tabuñar Scarlett Mia S. , Pagkatipunan Paulo Maria N.
Published: December 2023

Objective: In developing staffing plans for emergency departments (EDs), a multifaceted approach must be considered without compromising quality of care, patient safety and personnel satisfaction. This study aims to determine the temporal trend of patient attendance and staffing in a major tertiary hospital ED to assist in establishing an optimal staffing pattern.
Methods: A 1-year retrospective ED census review of adult patients at the University of the Philippines-Philippine General Hospital (UP-PGH) was undertaken. One-way analysis of variance (ANOVA) with post hoc Fisher-Hayter pairwise comparisons were utilized to determine if the ED consults and admissions were significantly (P<0.05) associated with the month of the year and day of the week.
Results:  A total 43,632 consults at the UP-PGH ED, averaging of 3,636 per month or 121 per day, were seen in 2019. Results indicated statistically significant differences between monthly [F (11,353) =16.45; P<0.0001] and between daily means [F (6,358) =4.19; P=0.0004]. The most number of consults occur during August, September, October and November while admissions were highest during April and October.  It was busiest during Mondays and afternoon shifts (1400-2200 hours) with majority arriving as urgent in acuity. Mortality was also highest during the afternoon shifts. 
Conclusion: The temporal variations in patient visits and acuity described in our study can be used as a template for workforce scheduling and resource allocation to meet the demands in the provision of care at the ED.

State terrorism on example of Putin’s regime: present and history
Authors: Krupenya Iryna , Podriez Yuliia
Published: December 2023

The article analyses current international documents that define the criteria of state terrorism. It has been demonstrated that the political decisions taken by the President of Russia Vladimir Putin in relation to Ukraine fall under the criteria of the Geneva Declaration on Terrorism. The scientific interpretation of state terrorism is explored here separately. Furthermore, the root cause of state terror in modern Russia is explained. The authors emphasise that Putin’s rule of modern Russia is no different from the way Peter I ruled the Moscow state, which was based on terror and violence. It is no coincidence that Vladimir Putin, after having visiting in June 2022 an exhibition dedicated to Peter I, compared himself to the tsar. It has been established by the authors that in the 16th century the departure from the tradition of Western-type civilizational development and the decline of the achievements of own culture were oddly combined in the territory of Muscovite Rus with society’s rejection of the basic principles of Asian order and culture. Elements of people’s democracy (freedom) were not entirely replaced by Asian despotism. Instead, a specific phenomenon of purely Russian ungovernability – popular rebellion and despotic arbitrariness – was formed. It is emphasized that the national consciousness was enslaved by both the Leninist and Stalinist administrative and political systems, where anti-Ukrainian rhetoric prevailed. It has been established that the Russian-Ukrainian war provides a historic opportunity for Ukraine to root out pro-Russian political forces and at the same time to hold Russia accountable for international crimes committed by its troops on the territory of an independent state on the direct instructions of Vladimir Putin.
Circulation and Exportation of the Japanese Childbirth Model in Southern-East Asia Preliminary Insights from Cambodia
Authors: Schantz Clémence , Petitet Pascale Hancart
Published: December 2023

Globally, maternal health matters and birthing ideologies and practices still generate much controversy. On the one hand, those who are promoting the medicalization of childbirth argue that the mortality and morbidity risks justify the imposition of biotechnological standards and practices. On the other hand, activists for demedicalization of birth are denouncing gynecological and obstetric violence, and pointing the pathologies induced by overuse of technologies. These movements, which are part of the current’s feminist calls, advocate a women’s reappropriation over their own bodies. The paper, based on long term and more recent ethnographical investigations aims to explore these political, cultural and social controversies by examining the recent initiatives in reproductive health domain carried by Japanese cooperation in South-East Asia. Since the 2000s, JICA (Japanese agency for international cooperation), as part of its infrastructure development, institutional strengthening and training programs, has indeed carried out numerous initiatives.

The V4 – ASEAN Perspectives Cooperation and Diplomatic Missions in Southeast Asia and Central Europe
Authors: Laš Lukáš
Published: December 2023

This paper provides an overview of diplomatic missions between Central Europe and Southeast Asia and draws a picture of the political, economic, and cultural interactions between the countries of the two regions on vertical and horizontal levels. Desktop research is combined with selected theoretical views on diplomatic representation and international cooperation. A particular attention is paid to the interaction of the Visegrad Group (V4) countries with the countries of the Association of Southeast Asian Nations (ASEAN). Descriptive empirical views are interpreted in a growing “Indo-Pacific” context. The potential of the V4-ASEAN cooperation format is recognized but not yet fulfilled, which is expected to change with implementation of the EU’s Indo-Pacific Strategy.

Authors: Özlü Şerif
Published: December 2023

With the increase of complex information in applications of decision making problems, the use of probabilistic hesitant fuzzy set structure has expanded. Therefore, this paper aims to present two new operators namely q-rung orthopair probabilistic hesitant fuzzy hybrid weighted arithmetic and geometric (q-ROPHHWAG) operator and q-rung orthopair probabilistic hesitant fuzzy hybrid ordered weighted arithmetic and geometric (q-ROPHHOWAG) operator for q>0. The presented operators are better than existing operators in many respects as adding a new parameter, having more flexible structure and presenting comparative analysis in its own. Moreover, we mention from some properties of the proposed operators. In addition to, we give an algorithm and example to indicate effective, reality and flexible of presented method and operators. Then, we solve an example over Pythagorean probabilistic hesitant fuzzy sets with our operators and the results are agreement and the offered operators have superior effect than other operators.
Prospective Applying of a Switched Reluctance Motor in the Traction System of a High-Speed Electric Train
Authors: Miroshnichenko Ekaterina
Published: December 2023

Purpose: The use of switched reluctance motor (SRM) in the traction system of a high-speed electric train by increasing the performance of its bearings. Using SRM as a traction electric motor, the machine-building complex can solve problems related to the import substitution of components for rolling stock. Methods: The main reasons for the wear of the bearing assembly are the forces of one-way magnetic attraction (OMA). These forces occur when the air gap is asymmetric due to errors in the manufacture of parts and deviations in the assembly of the electrical machine. The OMA forces at a certain displacement are determined using the Maxwell stress tensor. To achieve this, the finite element method embodied in the FEMM program has been used. The dependences of the currents in the corresponding phases on the moment of time required to find the forces have been obtained using the MATLAB program (SIMULINK). Results: Calculation and analysis of OMA forces is carried out at various variants of rotor displacement relative to the axis of symmetry of the stator, including at vertical shift in the direction of gravity action. Calculations have shown that OMA forces can reach significant values. A proposal has been put forward to limit the magnitude of the OMA force to the magnitude of the force at the maximum permissible residual unbalance. Methods are proposed to eliminate irregularity of the air gap at the stage of production. Practical significance: The results of the studies can be used by the developers in the design of the traction SRM, the selection of the structural value of the gap and the assignment of tolerances in its dimensional chain. The use of SRM with a long life of bearings in the traction drive system will create the prerequisites for obtaining a new competitive rolling stock.
Evaluation of the Performance of Magnetic Indicators for Magnetic Powder Control of Railway Rolling Stock Parts
Authors: Otoka Aleksandr , Holodilov Oleg
Published: December 2023

Purpose: To evaluate the performance of various luminescent magnetic suspensions on the example of individual small-sized parts of railway transport, differing in geometric shape, color, surface roughness and the presence of paint coating. To show the need to test magnetic suspensions, including ready-made ones, in aerosol cans on tuning (control) samples, taking into account the color, the presence of a non-magnetic coating, and other characteristics. Methods: Comparison of the obtained magnetic powder indications during wet magnetic powder control under conditions of magnetization of rolling stock parts by the applied field method using the MD-12PSH flaw detector. In practice, identical conditions have been maintained for magnetizing components at the center of the solenoid, uniformly applying magnetic suspension through aerosol can and sprayer to the surface, as well as inspecting for the presence of accumulations of magnetic powder particles under both daylight and ultraviolet irradiation. Results: The experiment has shown that the technical characteristics of the magnetic indicator stated in the passport by the manufacturer shouldn’t be fully trusted and relied on. At the same time, the use of one or more standard or tuning (control) samples with a huge range of control objects is not enough. Practice shows that, taking into account the fact that surfaces of parts differ, it is necessary to conduct a comparative analysis of magnetic suspensions for the brightness of powder glow, contrast, measured length of the magnetic indication on parts with artificial or natural defects with exactly the same surface. Practical significance: The article shows that it is necessary to use for each control object its own tuning or control sample. Only those objects of control that are identical or comparable in size, shape, color, roughness, and other characteristics fall under the exception. Therefore, only one sample can be used for them.

Purpose: To consider structural and technological aspects of construction of steel reinforced concrete span of road bridge over the Vetluga River. To consider the issues of creating a computational model in the Midas Civil program complex with regard to the presented requirements to meet the requirements of GOST and SP. To give a detailed analysis of the stress-strain state of the model on the basis of calculation of the created model. Methods: Analysis of the design and allocation of the main parameters; comparison of the calculation models obtained taking into account the stage of concreting of the monolithic reinforced concrete slab of the roadway and without taking into account the stage of work. Results: The stress-strain state has been analyzed, and the structural and technological features of the erection of a road bridge over the Vetluga River have been considered. It is established that stresses in metal main girders increase significantly in comparison with the model that does not take into account the stages of erection. The combined operation of steel and reinforced concrete section starts only after the monolithic reinforced concrete slab of the roadway has gained strength. It is established that the development of cracks in concrete in the support zones caused by negative moments can be accounted for by reducing the elastic modulus of concrete in the support zones by 8 times. The change of stresses and strains in the structure by stages has been analyzed. The stresses and deformations arising in the structure during its erection are "inherited" from one stage to another when calculating by stages. Practical signifacance: The methods of creating a reliable calculation model of steel-reinforced concrete spans, reflecting the actual nature of the work of the structure both at the stage of construction and at the stage of operation, are shown. The methods described in the article can be recommended for creating a calculation model in the Midas Civil software package with consideration of the presented requirements to meet the requirements of GOST and SP, as well as to avoid accidents at all stages of the life cycle of the structure.

Authors: Shevlyugin Maxim , Kulikov Andrey , Semenova Darya
Published: December 2023

Purpose: To reduce economic losses in the contact network (CN) and overhead lines (OL) electrified with alternating current. The existing electromagnetic influences on the alternating current railway lead to significant economic losses. Additionally, there is a problem of the contact wire (CW) burnout during the passage of a neutral section with a raised pantograph under voltage on a high-speed railway line (HSRL). CW burnout leads to failure of the contact network, repair costs, possible damage to other people’s property and rolling stock. As a whole, all this represents significant economic losses. Methods: The analysis of material and time costs for the elimination of problems that arise due to the CW burnout or due to the use of manual labor during the installation of OL has been carried out, in comparison with the proposed solutions to reduce economic losses. Results: In solving the problem of the negative electromagnetic influence of the contact line (CL) on the OL, a mobile mechanized complex (MMC) is designed to help, which performs the transposition of the OL wires in 6 steps with scrolling by 60° each support. This method will allow us to place the OL wires equidistantly from the contact wire. Scrolling with once-per-support frequency will align the asymmetry of the linear electrical parameters. All in all, MMC performs installation in an automated mode. The problems of the CW burnout can be reduced by the insulating coupling device (ICD) of the CL. ICD CL is a set of step resistances, which are located at the outer sections of the phase wires before and after the neutral section. It is aimed at reducing the current to a safe value, which will not lead to the contact wire burnout, failure of the CN and/or rolling stock and possible damage to other people’s property. Practical significance: The result is a set of measures in the form of MMC to reduce economic losses in overhead lines from the influence of CN and ICD CL to reduce losses in the contact network by maintaining the operability of the contact wire.
