Authors: Ortega Matías , Garzón Beatriz
Published: June 2020

La provincia de Tucumán, Argentina, viene creciendo en la concientización sobre la problemática de los Residuos Sólidos Urbanos (RSU), mediante la generación de instituciones gubernamentales, organizaciones civiles, cooperativas de trabajo, etc. El objetivo principal es dar cuenta de una práctica reciente en un sector urbano muy próximo al área central de la ciudad de San Miguel de Tucumán, en la que, a través de la vinculación tecnológica entre el sector social y el académico, se buscó propiciar condiciones de participación vecinal en la gestión del espacio público. Es así que la metodología seguida fue la Investigación Acción Participativa (IAP), buscando justamente generar conocimiento y trasformar con esto una realidad existente, mediante una dinámica participativa y colaborativa. Se realizó un relevamiento fotográfico planimétrico del área de interés para su análisis, se conocieron las percepciones de la comunidad involucrada mediante la elaboración de entrevistas y encuestas sobre el estado actual de la situación en el sector; se sistematizaron los datos cualitativos recabados y se redactó un informe diagnóstico preliminar. Como resultado se generó un proyecto piloto de Reforma Urbana sintetizando lo trabajado y generando una base para avanzar a nivel colectivo. Se organizó un taller participativo con los vecinos interesados y se asumió el compromiso para seguir trabajando en la gestión conjunta con el municipio capitalino y el ferrocarril, actores de la administración pública involucrados en el sector. Se concluye que la vinculación tecnológica entre diferentes sectores sociales es necesaria para promover la gestión colectiva del espacio público, concientizando sobre la recuperación de los RSU.

Terrestrial evaporation and global climate: lessons from Northland, a planet with a hemispheric continent
Authors: Lague Marysa , Pietschnig Marianne , Ragen Sarah , Smith Timothy , Battisti David
Published: June 2020

From a climate perspective, land differs from the ocean in several fundamental physical ways, including albedo, heat capacity, amount of water storage, and differences in resistance to evaporation. These differences alter the surface energy and water budgets over land compared to ocean, with implications for both surface climate and atmospheric circulation. In this study, we use an idealized general circulation model (Isca) to explore the climate state of Northland, a planet with a northern land hemisphere and a southern ocean hemisphere. These idealized simulations are motivated by the asymmetry of continental distribution on the globe, with a greater concentration of landmasses in the northern hemisphere and a larger area of ocean in the southern hemisphere, and further illuminate the basic role that land-sea contrasts play in global atmospheric dynamics. We find a much larger seasonal cycle of temperature over land compared to ocean, as expected. The continent is seasonally wet in the tropics, has a subtropical desert, and a moist high-latitude ``swamp, where moisture transported from the tropics accumulates. Decreasing the land albedo leads to warming. In contrast to past studies, suppressing evaporation from the land surface cools the climate, resulting from decreased atmospheric water vapor and reduced trapping of longwave radiation, which dominates over the warming associated with reduced evaporative cooling at the surface. The ITCZ in the Northland simulations extends farther polewards over both the land and ocean hemispheres than the ITCZ in an aquaplanet. Our results demonstrate the potential for land and hemispheric asymmetries in controlling the large-scale axisymmetric atmospheric circulation.

Undertaking a study on security issues, it is initially necessary to define the concept precisely, and to make it concrete. The term security, when used without any defining of its meaning, represents only a conceptual formation, which has no reference of existence in the material world. The aim of the article is to concretise this concept. To this purpose, it is necessary to indicate: to whom or what it may concern. In addition, in this article the author undertakes to indicate the perception of the situation for specific entities or objects with a possible insecurity or its opposite, i.e. safe situation. Possible threats caused by given subject, object and situation are also analysed.

Belt and Road Initiative w Afryce i jej wpływ na rozwój The Joint Africa–EU Strategy
Authors: Leszek Karolina
Published: June 2020

The purpose of the paper is to analyse how the progress of the Chinese Belt and Road Initiative (BRI) and the participation of African countries may affect the shape and development of the Joint Africa–EU Strategy (JAES), established in 2007. Since 2013, when BRI was presented to the world for the first time, we have been able to observe increased activity of representatives of the People’s Republic of China (PRC) in promoting and implementing the project. Due to the fact that BRI is going to connect the trade route of China with the countries of East Africa, Central Asia, the Middle East, and Europe, which is supposed to trigger the extension of the Chinese financial and infrastructure activities, it should be considered as a priority for the Chinese government. However, taking into account of still unclear concept of the initiative we should focus on analysing the impact of the Belt and Road Initiative on the European Union’s strategy towards African countries.

Authors: Shields Nora , Stukas Arthur A. , Buhlert-Smith Kirsty , Prendergast Luke A. , Taylor Nicholas F.
Published: June 2020

Purpose: The purpose of this study was to determine whether positive changes in self-reported attitudes toward disability were retained after students had participated in a 12-week voluntary community-based exercise programme for young people with disability. Method: Sixty-eight physiotherapy and exercise physiology students (45 women, 23 men; mean age 21 y) volunteered. Each student was matched with a young person with disability, and the pair exercised together twice a week for 12 weeks at their local gymnasium. The primary outcome measure was self-reported attitude toward disability. Secondary outcomes were self-reported professional skills competency, confidence, future work intentions, and motivations for volunteering. The outcomes were measured at Weeks 0, 13, and 24. The data were analyzed using generalized linear mixed-effects models, ordinal regression, and linear regression. Results: The students’ attitudes toward disability were more positive at Weeks 13 and 24 than at baseline, but positive changes were not fully retained by Week 24. Small statistically significant reductions occurred after Week 13. Self-reported skills competencies, confidence, and future intentions of working in disability were higher at Weeks 13 and 24. Students’ motivation for volunteering was wanting to support others, wanting to learn, and perceived positive career effects. Conclusions: Positive changes in students’ attitudes toward disability were generally retained 3 months after volunteering in a community-based exercise programme.
On the evaluation of the constrained studded pressing method for producing nanocrystalline copper sheets
Authors: Torkestani Ahad , Dashtbayazi Mohammad Reza
Published: June 2020

In this study, the experimental setup of a constrainedstudded- pressing method (CSP) as a severe plastic deformation process was investigated to produce nano-crystalline copper sheets. The sheets were CSPed up to 35 passes. The crystallite size and the dislocation density of CSPed samples were calculated by X-ray-diffraction pattern analysis. Also, tensile tests were used to investigate the mechanical properties of the CSPed samples. The results revealed that increasing the number of CSP passes augmented the density of dislocations, reduced the crystallite size to 124 nm (while for the as-received sample it was about 7.8 lm), enhanced the yield-strength and the ultimate-tensile- strength, and lowered the elongation of samples. This study for the first time has challenged the ability of the CSP method to produce nanocrystalline materials.
Charge transport measurements in compressed bulk graphene oxide
Authors: Onwona-Agyeman Boateng , Sun Yong , Hattori Hayami
Published: June 2020

Charge transport measurements in compressed bulk graphene oxide (GO) have been studied within the temperature range 15-450 K. Structural properties and surface morphologies of the bulk compressed GO were studied using X-ray diffraction and transmission electron microscopy. Raman and X-ray photoelectron spectroscopies were also used to confirm the presence of graphitic phases and the various functional groups in the GO, respectively. Current-voltage characteristics of the GO measured with gold (Au) electrodes at different temperatures showed no Schottky barrier at the Au/GO interface. At low temperatures and low bias voltages, the electron transport through the compressed GO sample showed no significant voltage dependence, which is consistent with a direct tunneling mechanism at all the bias voltages (0.01 -1.0 V). It was also observed that no Fowler- Nordheim transport mechanism occurred within this bias voltage range.

Authors: Li Congmin , Yin Yanguo , Xu Ming , Cheng Jianfeng , Shen Lan , Zhang Guotao , Chen Qi , Yang Bingxun
Published: June 2020

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.
Two-step annealing treatment for grain refinement of cold-worked AISI 316L stainless steel
Authors: Mirzadeh Hamed , Sharifian Kamyar , Kheiri Sara , Naghizadeh Meysam
Published: June 2020

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.

The development of the Ukrainian democratic state requires the creation of a qualitatively new national education system in order to ensure revival of intellectual and spiritual potential of the Ukrainian people. Teacher’s personality formation in this aspect is a complex multifaceted process. Education is one of the main problems of theory and practice of pedagogical education. Pedagogical activity in the field of pupils’ physical education is a specific form of activity aimed at the realization by elementary school teacher as constructive, communicative, organizational and cognitive functions of his professional activity. Elementary school teacher’s pedagogical work is characterized by a variety of professional responsibilities, which every teacher must be able to perform in a qualified manner. It demands from a teacher of high focus on the qualitative solution of pedagogical tasks (improving, educational, and educative) in physical education of pupils and also ethical communication with pupils, colleagues on service, parents of pupils. Pedagogical work of physical culture teacher at elementary school in consists in ability to realize aims, to unleash tasks on physical education of pupils. General and aged tasks of physical education are highlighted. General tasks of physical education, such as "strengthening of pupils’ health", "versatile physical development" "hardening of pupils" pass through the whole process of physical education from the 1st to the 4th grade. Pedagogical technology of elementary school teacher reflects tactics of implementation for educational technologies, is based on knowledge of  the regularities of functioning the system "teacher - environment - student" in certain conditions of study (individual, group, collective, mass, etc.). Common features and patterns of implementation for the educational process regardless of the specific educational discipline is inherent it. A teacher turns into a public figure responsible for each student during  all years of his  work at school,  having realized the main directions of professional work - study, upbringing and development of pupils, ensuring diverse physical development of a child.
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 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.

The article discusses the features of the interaction of players in the organization of group tactical actions in volleyball. The current state of sports training is characterized. The main methods for mastering and improving the interaction of partners in group tactical attack actions in a relatively short time are disclosed, which is essential in the training of qualified volleyball players.

The urgency of this issue is caused by the need to improve the system of sports training of students-volleyball players in connection with changes in state-administrative, structural, logistical and economic conditions of work, the need to educate healthy lifestyles in young people, one of the main factors of which should be daily occupation еxercise.

A specific feature of the game is that any technique is closely linked to other, executable teammates; players' individual tactical actions are a private expression of team tactics. The levels of physical and technical fitness of players and teams are gradually converging.

Nowadays, both in the international sports arena and in domestic competitions the sports competition is sharply sharpened. Volleyball teams fights are becoming more intense. The levels of physical and technical preparedness of players and teams are gradually approaching, and the scientific development of training methods in these sections of player training is widely known and allows to quickly eliminate the differences or lag behind the leaders of the world volleyball. In order to achieve victory in such conditions, the use of effective tactical means of conducting the game with active opposition of the opponent, which is characteristic of the modern stage of the development of volleyball, becomes of paramount importance.

The positive is well – proven numerous researches influence swimming on the health of occupying. Therefore question about affecting of employments swimming organism of young swimmers it is necessary to examine taking into account individual of anatomical and physiological features. The aim of the real research was a study of influence of physical activities of step - rising power on breathing and circulation of blood of youths 15-16, regularly visitant a section on swimming. A result of research of indexes of breathing and circulation of blood at the set loading allows describing functional possibilities of youths - swimmers. It was well - proven that the system of preparation of young swimmers was built taking into account age anatomical and physiological features of their organism, and physical activities were adequate to their physiological development. Modern living conditions are characterized by rapid development of automation of production and information technologies, which deprives a person of motor activity. Swimming is one of the most effective means of motor activity that positively influences the functional state of the cardiovascular and respiratory system. Numerous studies have already shown the positive effect of swimming on the health of the practitioners. It should not be forgotten that despite the significant differences in the functional state of the apparatus of external respiration and blood circulation in young swimmers and their peers - not athletes, the organism in both of them has not yet reached maturity and their age development and formation occurs in accordance with a single general biological regularities. Therefore, the question of the impact of swimming lessons on the body of young swimmers should be considered not only in terms of the impact on it of the specific features of the aquatic environment and the requirements of modern training, but also taking into account anatomical and physiological features.

The disadvantage of a medical approach to health lies in some traditional factors. First, doctors clearly distinguish between healthy and ill people (patients) and are ordinarily reluctant to deal with transitory conditions. In Ukraine, health improvement is primarily related to medical intervention and rarely to psychological, sociological or physical education. In addition, doctors do not take into account the wide variety of factors affecting humans, especially internal ones, and focus mainly on physical, environmental and biological causes of pathologies. However, a valeological approach to health includes medical, biological, psychological and social factors. Most importantly, it elaborates a philosophy of health, which allows one to improve it at all levels of human activity. Thus, health is seen as a personal matter rather than the object of medical research. The ontological basis of valeology connects it with other social and even global aspects of humanity, including spiritual and creative development, prevention of violence, protection of rights and freedoms, which, taken together, imply developing humanism in the broad sense. The justification of valeology-oriented learning and life is somewhat complicated since health is acknowledged as a value in case of its loss or threat to it. The main task of the teacher is to overcome valeological factors which negatively affect the consciousness supporting health preservation and promotion. In addition, there is a new stereotype among the general population that doctors are “unprofitable” for the patient to heal: financially, medicine seems to be interested in maintaining long-term, process-oriented, rather than result-oriented therapy. The ontological basis of valeology connects it with other, social and even global aspects of humanity.

The conducted studies indicate various quantitative indicators of technical and tactical actions of players of different game roles. So, for goalkeepers, the largest percentage of technical and tactical actions is in long (29.8%), short (27.2%) and medium transfers (21.5%). Extreme and central defenders are more likely to perform short (29.3; 28.4%), medium (26.2; 30.8%) and long-range transfers (12.6 and 17.0%) with a relatively small amount of reference the ball (8.1 and 7.6%). Midfielders (extreme and central), in addition to a large number of transfers (short - 28.6 and 29.4%; medium - 25.7 and 26.6%; long - 12.5 and 13.2%) stroke (9.8 and 7.8%), dribbling the ball (8.0 and 8.2%) and stopping the ball for further playing action (9.2 and 9.4%). Forwards mainly use short (28.8%) and medium (25.0%) assists, as well as stroke (16.2%) and dribbling (9.8%). The results obtained indicate that for most indicators of technical and tactical actions, there is a significant difference, which requires the study of the predominant use of some of them by players of different game roles. Improving the technical and tactical training of young footballers at the present stage requires the implementation of new, scientifically sound approaches to the construction of the training process, starting with the initial stages of many years of training. The process of training young players covers a considerable time span of several years, and this period is marked by significant physiological changes in the body of athletes associated with growth and development. According to many authors, real training of a young athlete is impossible without taking into account the patterns of the developing organism. Much attention has been paid to the development of the concept of age-related dynamics of physical qualities in the theory of child-youth sports. Modern research in the field of children's youth football draws the attention of scientists including technical and tactical.

The author is of the opinion that today, education is under active reconstruction as personal or individually oriented development and confronts researchers lot of questions.

Personal interaction in the educational process should be based on the internal needs of the teacher to be the most disposed to dialogue with the student, on cooperation and co-creation. Humanistic position of the teacher should be based on maintaining a teacher of his personal integrity and understanding of the integrity of the individual student. Personal approach in education can be understood as a joint activity based on the realization of opportunities of the person as a pupil and teacher. The essence of this approach involves the integrity of the personality of the teacher.
