Published: June 2020

Abstract
The microstructures of an Al-Bi immiscible alloy and the corresponding composites containing TiC (1 wt.% and 2 wt.%) were explored for melt temperatures of 800 °C, 850 °C, and 900°C. It was demonstrated that serious coarsening and macrosegregation of Bi-rich minority phase particles occurred, which was slightly alleviated by increasing the melt temperature from 800 °C to 900 °C. By adding TiC particles, the coarsening and macrosegregation of Bi-rich minority phase particles were significantly impeded. Scanning electron microscopy and energy-dispersive X-ray spectroscopy revealed that TiC particles were located inside and on the surface of Bi-rich minority phase particles, exhibiting heterogeneous nucleation and self-assembly behaviour. By properly increasing the holding time of the melt, finer and more uniform Bi-rich minority phase particles were obtained.

Published: June 2020

Abstract
Two-step annealing after cold rolling is proposed for the optimization of the annealing process of AISI 316L austenitic stainless steel toward more intense grain refinement. It was revealed that the first step of the annealing process at lower temperatures (i. e. 750 0C) can be used for the reversion of strain-induced martensite to austenite without uninhibited grain growth and recrystallization of the retained austenite. Afterwards, the primary recrystallization of the retained austenite takes place in the second step of the annealing process at higher temperatures (in the range of 850 to 950 0C). Carefully controlling the second annealing step resulted in a finer grain size and better mechanical response compared to those of a conventional one-step annealing approach.

Authors: Bismak O. , Safontsev D. 
Published: June 2020

The article highlights the use of mechanotherapy in traumatic injuries of the peripheral nerves of the upper limb. Damage to the nerves of the upper extremities is one of the frequent and severe types of injuries that can dramatically change the quality and lifestyle of a person, both in everyday household and professional environments. The classification of simulators and mechanotherapeutic devices that are advisable to use for traumatic neuropathies of the upper limb, the principles of motor rehabilitation. It is noted that mechanotherapy can be used to facilitate the execution of any movement (robotic mechanotherapy) and with the goal of training with increasing intensity, aimed at strengthening the motor, cardiovascular and respiratory systems (active mechanotherapy). The characteristic of the main robotic devices that are used to train hand function with the presence of feedback and the use of a gaming or virtual environment is given. It is noted that the modern direction of training rehabilitation is robotic mechanotherapy, the basis of which is the use of robotic devices for training hand function with the presence of feedback and the use of a game or virtual environment.The advantage of robot therapy is a higher quality of training compared to classical mechanotherapy due to the greater accuracy of repetitive cyclic movements, a constant training program, the availability of tools to assess the success of the classes with the possibility of demonstration to the patient. Robotic devices in rehabilitation treatment of the upper limb include MITMANUS, ARM Trainer, mirror-image motion enable (MIME) robot, Armeo, etc. The authors draws attention to the fact that training on modern simulators and devices in no way replace traditional means of physical therapy and should be used in conjunction with other rehabilitation measures in neurological patients.

Published: June 2020

The article discusses a relevant topic that is developing and requires attention to promote the development of a harmonious personality of the younger generation and the identification of value orientations, respectively.
The present tells us that the gender approach in physical education acts as an opportunity to expand the horizons of life, individual abilities and the makings of each person. After identifying these features, which in the future will contribute to a greater involvement of students in physical education and increase their motivation for classes, which as a result will ensure the growth of a healthy nation. By taking into account the gender characteristics of value orientations toward physical education, not only the physical condition, but also the spiritual one is improved in the personality, which contributes to the harmonious development of it. Human activity is carried out through the formation of motives and interests, choice of means, process of activity and result. The formation of their motivation is influenced by various factors (external and internal). Research of limiting and stimulating factors of motivation to physical activity and observance of factors of healthy lifestyle of persons of different sex will give an opportunity to determine organizational-methodical conditions of involvement of more children, teenagers and young people in systematic physical training and sports.
The authors argue that taking into account the gender stereotypes of adolescents in relation to physical culture and sport will help to influence their involvement in various types of physical activity, which will facilitate the realization of gender equality in the field of physical culture and sports.
The purpose of physical culture of the individual - the comprehensive and versatile development of physical and spiritual abilities of man, his self-realization in the development of spiritual and physical abilities through physical activity, the development of other values of physical culture.

Education of endurance in children of middle school age in lessons of physical culture
Authors: Portnaya I. , Ivanko V. 
Published: June 2020

The influence of a set of exercises on the development of endurance of secondary school students is revealed in the article. One of the factors that adversely affects the health of school-age children is the low mobility of life. Therefore, physical education occupies a special place in the system of physical education of school-age children. Physical fitness testing is an element of stage control both in the sports training system and in the practice of physical education. However, the ability of children of different ages to exercise some physical activity is limited by the adaptive potential of the growing organism's systems, and as practice shows, the reserve capacity of the student body is significantly reduced, which negatively affects the physical qualities of children, and especially endurance. Endurance is considered one of the basic motor abilities of the person. The endurance index with great precision indicates the overall health of the person and the functionality of the respiratory and cardiovascular systems. Analyzing the indicators of the level of endurance development in the studied contingent of children it is established that the level of endurance development of students of 4-5 grades, is equal to the mark of 3 points, which corresponds to the "average level". The study shows changes in the level of endurance development in students engaged in the recommended complexes and the relationship of endurance types with indicators of overall physical performance. The results of the correlation analysis showed the presence of a high correlation of static endurance with dynamic endurance (r = 0,883). Also, a high statistical relationship is observed in the study of the relationship of dynamic strength endurance and speed-endurance (r = 0,858). Preparing a physically healthy and in all respects advanced generation is an important task of our society. Properly organized physical education and sports, which should be included in the daily life of young people from an early age, occupy the first place in this task.

The article deals with the problem of physical therapy after total hip arthroplasty. The urgent issue of early mobilization and activation of patients after total hip arthroplasty by means of physical therapy is raised. The purpose of the article is to evaluate the effectiveness of the proposed complex of means of physical therapy of patients after total hip arthroplasty.
The study involved 16 patients at the Clinic of Orthopedics, Arthrology and Sports Injury, which were divided into two groups: control and primary, 8 people each.Empirical research methods were the WOMAC Western Ontario and Mc Master Universities osteoarthritis Index and the Leken algal function index. The main group was engaged in the method of N. Kehlet, active mobilization of patients began in the first day after surgery, the control group received traditional physical therapy with verticalization on the second day after surgery. The average hospital stay was 7 days. This is due to the requirements of the surgeons and does not depend on the functionality of the patient. Physical therapy after surgery was aimed at: reducing swelling; prevention of blood clots; pain control; prevention of constipation; improving sleep; improving postural control; increasing exercise tolerance.
At the present stage, the method of total hip replacement is one of the progressive and widespread types of surgical treatment of coxarthrosis. Today, due to the introduction into clinical practice of high-efficiency technologies of prosthetics, the use of modern joint designs, orthopedic surgeons in most cases manage to achieve effective results and restore lost function.
The patients of the main group had reached the functional criteria of discharge several days earlier. The study are presented, according to the results of which we believe that the work by the method of N. Kehlet is quite effective and that it should be used in working with middle-aged persons after total hip replacement due to deformable coxarthrosis.

Expand and deepening of detailed researches into the problems of training future primary teachers in physical education is very necessary under modern conditions. Scientists pay special attention to the creation and introduction of active methods of study, the skilful use of which would contribute to increasing efficiency in the acquisition by students of professional knowledge, skills in the organization of physical education process of pupils. Physical culture lessons in their modern format are insufficient in themselves to maintain health of children, because they are often carried out unskilled, uninteresting, which creates an additional study load, negative attitude of pupils to school physical culture is produced as a kind of secondary educational subject. There is a hopeless situation under such conditions, at first sight. Therefore, the way out of the situation that now has developed is to review fundamentally tasks, essence, functions, forms and technological foundations of physical education at school. First of all, it is necessary to go beyond the traditional perception of physical culture as means of conducting only appropriate lessons. Physical culture should be considered a key component of human culture and not only as the development of individual physical qualities of the body, as universal means and prerequisite for the formation of all qualities of the individual - ethical, emotionally and strong-willed, intellectual and creative, permissive-entertainment, spiritual in general. The activity components of the organizer of sports and mass work at primary school, listed in the research, are interconnected, constitute the main content of the structure of his abilities, although they are constantly improved in the processes of their manifestation. Also our observations convince that each individual teacher is most often dominated by some one of the components just named. One teacher is well produced with organizational tasks, another with Gnostic, and another with communicative tasks. This is the individual style of activity and the development level of his pedagogical abilities.

Published: June 2020

The article examines the motor activity of students of musical arts using the Framingham method and identifies the ways to increase it through organized recreational activity and rational organization of free time.
The data revealed a significant decrease of average indicators and lack of higher levels of motor activity for students of musical art. The total value of daily motor activity at basic, sedentary, and small levels is 91.6% among students. The assessment of motor activity showed that students of I and II year do not exhibit high levels of motor activity. Students in their third year of study showed very low motor activity.
It is revealed that a lack of motor activity in students of music arts is associated with the static standing/sitting position to improve professional skills and the irrational distribution of free time.
The results obtained prove that it is highly important to increase the motivation of students of musical arts to exercise and engage in sports.
