Development of a model for assessing the technical condition of Baghdad bridges

The research aims to develop a significant model for assessing the condition of bridges. This model may serve as a supplementary source of information in determining bridge condition ratings not only in Baghdad, but also in other regions with similar operating conditions. The authors also used the methods of mathematical statistics, probability theory, and mathematical theory of planning to conduct an experiment using the results of bridge survey. Currently, the Commission on Audit uses financial depreciation models to determine the service life of structures, with no alternative formulas available for predicting this parameter in the country. Therefore, the authors consider a new approach on the basis of available research on depreciation models. This approach is based on assessment of the condition of 30 structural elements of a bridge, as well as the results of inspections conducted by the Department of Public Works and Highway Bridges. The purpose was to determine the applicability of available data as meaningful variables in identifying a regression model to predict the condition of such bridges in Baghdad. Statistical data for determining the coefficients and dependent variables provided a relevant model for bridge condition assessment, which can be applied to identify the technical state of bridge structures.

RESEARCH OF CHANGES IN THE POWER OF CAR FLOW AT THE SHUTTING STATION DURING THE PERIOD OF MILITARY ACTIONS

It is impossible to solve the problem of improving the system of organizing car flows in trains at the current level of information support without creating an information and management system that will integrate into a single information and computing space the most important optimization tasks covering all levels of managing the process of freight transportation on railway transport, such as such as the calculation of the routing of car flows from loaded and empty cars, the calculation of the plan for the formation of freight trains at the training ground of the main technical stations, the calculation of the plan for the formation of local trains in the areas of local work, and the construction of adjusted operational plans for the operation of stations. The aggression of the Russian Federation against Ukraine fundamentally changed the system of railway transport of Ukraine. The volume of cargo transportation by rail transport during military operations in the east of Ukraine decreased by 37% in 2022, but already in 2023, an increase in the transportation of some types of cargo began, in particular, grain cargo, mineral construction materials, dangerous bulk cargoes, military equipment. Transportation of goods by railways of Ukraine, especially during military operations, is not carried out evenly over a long period of time and has fluctuations in the capacity of car flows. The updated directions of their tracking, which depend on the technical condition of the railway infrastructure for the current period, lead to a change in the direction of tracking of car flows and, as a consequence, their organization into trains according to the formation plan at technical stations. The conducted studies established that the capacities of car flows are random values, therefore it is advisable to use mathematical statistics methods for their description, and modeling methods for forecasting work with them. Those car flows that arrive at the sorting station most of all fall under the geometric law of distribution of a random variable depending on the power of the direction of arrival, which has a significant impact on the accumulation parameter at the station. Fluctuations in the capacity of car flows are quite significant and depend on a sufficiently large number of factors. For the operational planning of the work of sorting stations, it is necessary to take the characteristics of the current state or a sample of data for short periods (a decade, a week), that is, it is necessary to constantly analyze the data from the ASK of the VP UZ - there is, therefore, a study of the capacity of car flows in the technical station during the period of changing their directions is an actual task and can be used to adjust the dispatcher routing and the plan for the formation of single-group and group freight trains.

STUDYING THE PECULIARITIES OF PHYSICAL ACTIVITY OF STUDENT YOUTH

Statement of the problem. Insufficient motor regime is caused by prolonged staying at home during classes and a large volume of academic subjects has a direct impact on the state of the student's body. Prevention and overcoming of these consequences is possible only through the introduction of a sufficient amount of physical exercises in the educational process of students. The study of various aspects of health has shown that each component is an important on the way to strengthening and improving the performance of college students. The purpose of the study is to analyze the physical activity of first and second year students of different pedagogical specialties. Research methods: pedagogical observation, questionnaire, methods of mathematical statistics. Results. The study established the concept of a healthy lifestyle and its main components. It has been found that physical activity is the most important indicator of a healthy lifestyle, and the lifestyle of student youth is a way to integrate the needs of the student. A questionnaire was conducted to assess the lifestyle of students of pedagogical specialties. The preferences and priorities, motives and factors that motivate students to be active were identified. According to the survey, students assess their health status differently: 33.4 % believe they have no health problems, 36.1 % of students believe they have minor health problems, and 30.5 % of respondents consider their health to be unsatisfactory. Instead, only 25.2 % of all students surveyed engage in health activities outside of class time, while 74.2 % prefer additional tutoring sessions with tutors. Conclusions. It has been established that different sources of information and the environment in which students live directly affect the formation of a healthy lifestyle. That is why it is necessary to reorganize and improve the system of physical education in educational institutions by forming motor activity models of student youth.

Materials and methods. The survey involved 350 respondents (senior students, residents, practicing physicians) mainly from Moscow medical higher education institutions. Statistical analysis was carried out using the software StatTech v. 3.0.4. Methods of mathematical statistics: U-Mann-Whitney, Kruskal-Wallis, χ2 -Pearson tests. Results. It was revealed that only 52% of respondents consider the amount of theoretical knowledge acquired at a higher education institution under a specialty program to be sufficient. Students and graduates of the pediatric faculty more often consider the amount of theoretical training sufficient compared to respondents from the medical and dental faculties (p < 0.001). Only half of the respondents are satisfied with the quality of the education received. Students and graduates of the Faculty of Pediatrics more often stated that they use the knowledge and skills acquired during practical training in their professional activities (p < 0.001). Students and graduates of medical faculties of non-core Moscow universities and Russian National Research Medical University named after N.I. Pirogov are most satisfied with the amount of theoretical knowledge received within the framework of the specialty program compared to students and graduates of other higher education institutions (p < 0.001). Conclusion. The results of this study may be valuable for government agencies that determine strategies for the development of higher medical education in Russia, as well as for university leaders who plan targets for the development of educational activities with an emphasis on involving students in the educational process.

ASSESSMENT OF PHYSICAL FITNESS OF MATURE WOMEN WITH DIFFERENT TYPES OF POSTURE

Relevance of the research topic. The systematization and generalization of a wide layer of both theoretical developments and practical achievements in the field of physical culture and sports serve as a basis for stating that maturity is the longest period of ontogenesis, characterized by the tendency for a person to achieve the optimal level of development of his spiritual, intellectual and physical potential. Against this background, the age of maturity in women, according to numerous data from representatives of the scientific community, is a period of motor deficit. The consequences of the latter include, first of all, the gradual unfolding of involutional processes, negative changes in the hormonal background, the appearance of excess weight, a decrease in the elasticity of connective tissue, the appearance of the first signs of structural and functional disorders of the spine and joints. The purpose of the article is to determine the level of physical fitness of women aged 36-40 with different types of posture. Methods. Theoretical analysis of special scientific and methodical literature, pedagogical testing, methods of mathematical statistics. The results of the work. The assessment of physical fitness of women in the second half of mature age showed the following. Firstly, it was found that according to tests of strength, endurance and flexibility, women aged 36-38 were more physically fit, performing pull-ups in a lying position mainly at an average level, tilting the torso forward from a sitting position and lifting the torso in a sitting position at a sufficient level. In contrast, the physical fitness of women aged 39-40 years was much worse, in particular, most of them performed lying pull-ups at a low level, torso bending forward from a sitting position and lifting the torso in a sitting position at an average level. Secondly, the comparison of groups of women aged 36-38 and 39-40 years, taking into account the type of their posture, did not reveal any differences in pairs of different ages of each type. At the same time, it was found that women with normal posture performed much better than the other groups in exercises such as flexion and extension of the arms in a lying position, pull-ups in a lying position, and women aged 36-38 years were superior in the test of lifting the torso into a seated position. Accordingly, women with a round, flat back and scoliotic posture were less physically prepared to perform these exercises.

Особенности сжигания композиционных водоугольных топлив

Russia has large coal reserves, on the average up to 173 billion tons. Although, the share of coal generation in Russia is relatively small (about 20–22 %), it reaches 65 % in the Siberian Federal District. Russia cannot deny coal, but it is necessary to update and improve energy efficiency of Thermal Power Plants (TPP) and boiler houses that burn coal. Currently, technologies have been developed to produce and use composite coal-water fuel (CWF) with various additives, primarily of organic origin to improve its target characteristics. A study of the characteristics of such coal-water suspensions has proved the promising outlook of their use as fuel in large and small Thermal Power Plants, both from an economic and environmental safety points of view. However, the lack of experimental data on the issues of combustion of composite coal-water fuel in bench-scale and semi-industrial conditions hinders the further development of CWF technology. Thus, it is relevant to study the features of combustion of composite coal-water fuels from coals of varying degrees of metamorphism. To prepare experimental batches of composite CWF, raw coals and coal slurries of various stages of metamorphism (grades D, SS, T) have been used. They were burned in a bench-scale semi-industrial plant. The research results have been processed using the methods of mathematical statistics and regression analysis. The influence of mechanical activation of CWF on the viscosity and temperature of its ignition and combustion has been established. The features of combustion of composite coal-water fuel using pneumomechanical injectors of two types are determined. The composition of harmful emissions during the combustion of CWF has been determined. The possibility to use composite coal-water fuel to ignite high-power boilers has been established. It has been proved that the combustion of CWF is environmentally safer compared to the combustion of coal and other types of fuel.

Investigation of the mechanism of sediment formation in sedimentary rock-forming compounds

For the successful application of water-limiting technologies and methods of regulating the extraction process, which increase the effectiveness of anti-flooding measures, it is necessary to conduct a comprehensive study, including analysis of the geological and physical condition, development of rheological and filtering characteristics of the compositions used. This article presents the indicators selected as criteria for the effectiveness of isolation of aquifers with polymer solutions - with a change in one group of geological– physical, technical and technological factors characterizing the well and processing technology. Thus, the conducted studies have shown that the amount of sediment formed can be adjusted by choosing the appropriate concentration of polymer and alkali for each specific case of treatment of the bottomhole zone of the well, and thereby the effectiveness of limiting using sedimentary gel-forming compounds is achieved. In the article, we have processed the results of experimental studies using methods of mathematical statistics. At the same time, we have established the dependence of the amount of sediment on the concentration of alkali at a stable value of the polyacrylamide concentration.
