Return to training after coronavirus (SARS-CoV-2/COVID-19) infection

The coronavirus pandemic raises an important issue of the return professional and amateur athletes to training after COVID-19 infection. Since no standard protocols for return to sports after the new coronavirus infection are approved to date, and few studies were done on SARS-CoV-2 infection short- and long-term complications in sports professionals, the question arises about the criteria for the athletes’ training restart after COVID-19 infection to protect the health of athletes and prevent long-term adverse health effects. This review is a synthesis of currently available information on the athletes’ re-involvement into the training process after COVID-19 infection

Interrelation of social and psychological adaptation and tendency to deviant behavior of students

© Canadian Center of Science and Education. The tendency to deviant behavior of students is a negatively affecting factor to the success of their socialization. Its actualization can lead to serious consequences, and become the reason of personality degradation even its death. Some reasons of the tendency to deviant behavior are violations of social and psychological adaptation. The interrelation of positive and negative factors of social and psychological adaptation with the tendency to various forms of deviant behavior is studied in this research. It is established that students' positive elements of social and psychological adaptation, such as high adaptation, self-acceptance and acceptance of others, internal control negatively effect on possibilities of the tendency development to various forms of deviant behavior. As for negative elements of social and psychological adaptation, such as disadaptation, self-unacceptance and unacceptance of others, emotional discomfort, external control and escapism can lead to strengthening of the tendency to deviant behavior. Positive and negative elements of social and psychological adaptation on the tendency to deviant behavior of students-boys are much lower than that of students-girls

Effect of liquid-phase sintering as a means of quality enhancement of pseudoalloys based on copper

Abstract. The effects of the liquid phase of a metal binder on the microstructure and properties of self-diffusion gradient composite (Cu - Al – ZnO) were investigated. For the compositions considered, it was revealed that at the temperature of about 550 °C, a liquid phase binder forms from nanoparticles Cu – Al. Applying a proper amount of a (Cu – Al) binder appeared to be beneficial for fabricating gradient composites with the desired self-diffusion process. It is also favorable for mass transfer of additives nanoparticles into the volume of a matrix during sintering and for the desired fine microstructure and mechanical properties. For the experimental conditions considered in this study, the best mechanical properties can be obtained when 6 mass % (Cu – Al) of ligature were used, which gave hardness HB at 120, electroerosion wear – 0.092 • 10-6 g / cycle, resistivity – 0.025 mcOm
