Authors: Kasich N. , Bondar T. , Krivobok T. 
Published: March 2024

Purpose: to reveal the peculiarities of the influence of music in the process of teaching swimming to students. Methodology: the work used analysis and generalization of methodological, psychological- pedagogical and educational-methodical literature, analysis of the educational process of teaching swimming to students, generalization of the author's own experience of teaching swimming to children and adults, pedagogical observation, questionnaires, surveys.
Scientific novelty: The article is devoted to the issue of optimizing the process of teaching students to swim in sectional classes on physical education with the help of music. In our turbulent time in the conditions of Russian aggression, one of the most important issues is the physical development of youth and students. One of the most important means of physical education is swimming. Mastering swimming skills is an important means of preventing accidents on the water, improving the physical development and adaptive capabilities of the students' bodies. The use of music during sectional classes helps students to concentrate and optimize their sports achievements. Despite the presence of a certain number of publications on swimming teaching methods, the problem of special selection of music to optimize this process remains almost unexplored. A selection of specific musical compositions for relaxation and achieving a tonic state of student swimmers is presented.
Conclusions: the introduction of a new system of learning to music allows students to relax, distract from fear, improve learning conditions, which, in turn, stimulates students' desire to acquire the vital skill of swimming.
We note that along with the existing traditional approaches to teaching swimming, the issues of developing a program for mastering swimming skills with the use of music remain unresolved, which requires further research.

The process of physical education of schoolchildren in institutions of general secondary education should ensure proper physical fitness of its pupils. However, the data of numerous surveys of a wide contingent of students indicate a low level of physical fitness, which is primarily due to insufficient development of physical qualities. The emergence of negative cases during physical education lessons in the institution of general secondary education in recent years requires the use of such effective means that without much stress affect the physical fitness of schoolchildren.
The purpose of the work is to determine the dynamics of the general physical fitness of 16-17-year-old boys during sectional athletics classes.
Research results. The established indicators of physical fitness for the experiment formed the basis for further selection of means aimed at increasing the level of physical fitness of high school-aged boys.
Thus, in the experimental group, a section on athletics for young men was created. Classes were held after school twice a week: on Mondays and Thursdays, lasting 60-90 minutes.
Classes in the athletics section contribute to better assimilation of the program material, make it possible to significantly expand and deepen the scope of acquired skills and abilities, and increase the level of physical fitness. While conducting the preparatory part of the sectional class (warm-up), we drew the attention of the young men to the need to remember the exercises, their dosage and sequence. It was explained that a properly conducted warm-up helps prevent injuries and more effectively solve the tasks. Periodically, we offered the young men to warm up first in small groups, and then individually. When learning new exercises, in order to avoid mistakes, they were first demonstrated.
Conclusions. The dynamics of growth rates of physical fitness indicators of young men during sectional athletics shows that the greatest progressive changes were achieved in indicators of speed, endurance and speed-strength qualities.

Scientific and methodological approaches to the problem of implementation and realization of health-oriented technologies of students of medical groups are disclosed in the dissertation research.
The solution of important issues regarding the deterioration of the state of health of student youth, a decrease in the level of their motor activity, an insufficient level of motivation for physical education classes, which requires the creation and implementation of practical measures aimed at the implementation of modern technologies in the process of physical education of students of a pedagogical profile with weakened health, remains relevant. The choice of the research topic "The method of teaching physical exercises by means of sports games for students of the pedagogical profile with weakened health" is due to the need to increase the effectiveness of the process of physical education of students of pedagogical profile with weakened health, which meets socio-economic requirements and is carried out under the "condition of implementation" of health learning technologies in the process of physical education of student youth. The proposed model of the methodology of teaching physical exercises and the development of physical qualities by means of badminton in the process of physical education of students of a pedagogical profile with weakened health, we propose to present as a system with defined components, which is formed by the totality, subordination and ratio of internal connections between its elements. In this regard, the motivational and target component is the main, system- forming part of the learning process and includes the purpose, tasks, functions and orientation of physical education of students of the pedagogical profile with weakened health, which contributes to the formation of students' motivation and a conscious attitude to the educational process of physical education, its means and methods, independent motor activities, the desire to constantly improve physical culture and sports skills.

Mild blast-induced traumatic brain injury is common among the military, resulting in cognitive impairment, reduced socialization, which leads to disability and, as a result, a deterioration in the quality of life. It is considered that blood-brain barrier disruption and microvascular dysfunction are the key to this type of injury. The purpose of study was to study changes in brain vessels after air shock wave exposure. The study was carried out on 48 mature male Wistar rats, which were randomly divided into 2 groups: an experimental group, in which animals were subjected to inhalation anesthesia using halothane and exposed to a shock wave with an overpressure of 26.4±3.6 kPa, and a Sham group. After simulation of injury on days 1st, 3rd, 7th, 14th, and 21st, the rats were euthanized and the brain was removed and after all subjected to standard histological procedures and stained with hematoxylin and eosin. For immunohistochemical studies, as primary antibodies were used eNOS. The finished preparations were examined by light microscopy and photographed. Disorders of the cerebral vessels in experimental rats were detected from day 1st of the posttraumatic period. It was found that the blast wave led to vascular rupture, as well as increased vascular permeability with diapedesis of red blood cells and cerebral edema for up to 21st days. Focal violations of the vascular wall integrity in cortical and hippocampal hemocapillaries, venular link of the submembrane vessels; changes in the morphology of the metabolic vessels endothelium; uneven blood filling of the brain vessels were of major importance. These changes indicate that increased eNOS expression leads to dilation of cerebral vessels, which is a compensatory mechanism in response to injury to improve cerebral blood circulation. However, eNOS is not involved in vasodilation, which we observed up to 21st day post-trauma.

Quercetin is a flavonoid with potential health benefits and it may help prevent cardiovascular diseases, reduce the risk of degenerative brain processes and cancer, and has antioxidant properties that neutralise free radicals. Substances in this group also have antioxidant properties, which help the body protect itself from the harmful effects of free radicals by neutralising these unstable molecules. Research indicates that the impact of free radicals on cell structure is associated with the development of chronic diseases such as diabetes, cancer, and cardiovascular pathologies. The aim of the study was to investigate the effect of quercetin administration on electron microscopic changes in the interstitial endocrinocytes of the testes under long-term central blockade of the synthesis of luteinising hormone by tryptorelin. The experiment involved 35 sexually mature male white rats. They were divided into two groups: the control group (I) received saline, while group II received subcutaneous injections of tryptorelin at a dose of 0.3 mg of active ingredient per kg of rat body weight to induce experimental central deprivation of luteinising hormone synthesis and additionally, quercetin was administered three times a day by gastric tube in terms of body weight. The study has demonstrated that the administration of tryptorelin results in structural and functional changes in the connective tissue components of rat testes. Specifically, there are quantitative and qualitative disorders in the population of interstitial endocrine cells, as well as electron microscopic changes at the subcellular level. Various pathological changes and abnormalities in the functional activity of the internal components of the cell were detected on days 270 and 365 of the experiment. The frequency, number, and size of Reinke crystals in relation to the cell volume correlated with changes in cells and increased at later stages of the study. A similar correlation with testosterone levels has not been found in the literature, which leads us to classify Reinke crystals as the result of degenerative processes in the cell. Thus, additional administration of quercetin reduces the adverse effect of tryptorelin and delays the onset of changes in the structure of interstitial endocrinocytes from day 180 to later observation periods.

Performance and Causes of Failure for Circumferential Welds and Welded Branch Connections for 23Cr-45Ni-7W Alloy Under Internal Pressure Conditions
Authors: Kubushiro Keiji , Tokuda Kenji , Nomura Kyohei 
Published: March 2024

Abstract
23Cr-45Ni-7W alloy (HR6W) is a material being considered for use in the high temperature parts of A-USC boilers in Japan. In order to establish an assessment method of creep damage for welded components made using HR6W, two types of internal pressure creep tests were conducted. One is for straight tubes including the circumferential weld and the other is for welded branch connections. The test results for the circumferential welds ensured that the creep rupture location within the area of the base metal, as well as the time of rupture, can be assessed by mean diameter hoop stress. On the other hand, the creep rupture area was observed in the weld metal of the branch connections, although the creep strength of Inconel filler metal 617 was higher than that of HR6W. FE analyses were conducted using individual creep strain rates of the base metal, the heat affected zone and the weld metal to clarify this difference in the failures of these two specimens. Significant stress was only produced in the weld metal as opposed to the base metal, due to the difference in creep strain rates between the welded branch connections and creep crack were initiated in the weld metal. The differences between the two failure types were assessed using the ductility exhaustion method.
