The article is devoted to the issues related to the phenomenon of “aging society”. The relevance of creating a barrier-free environment for the elderly is dictated by the current demographic trend towards an increase in life expectancy, an increase in its quality. The number of centenarians with functional impairments (senile dementia, Parkinson’s and Alzheimer’s) who require care at a qualitatively new level is increasing. Innovative form of organizing the leisure of the elderly «Kindergarten for the elderly people» is considered as one of the ways to solve the problem. Based on the data of a study conducted by the Federal state budgetary educational institution of higher education of the Far-Eastern state medical university of the Ministry of Health of Russia in 2020, identified the need to create a social institution «Kindergarten for the elderly people». The article notes the need for older people to adapt to the changing conditions of their life in the society saturated with gadgets and information.

Realizing conversion between fluid power and mechanical energy, the closed circuit axial piston transmission (CCAPT) plays a vital and indispensable role in miscellaneous industries. The frictional loss and leakage loss inside the system give rise to the inevitable temperature rise. In order to prolong the life of the device, a cooling structure on the outside of the CCAPT is designed for promoting heat dissipation. Based on the relevant heat transfer law and the temperature distribution of internal machinery elements, a spiral fin structure is designed at the shell side. With the help of numerical simulation, the effects of fin height, fin pitch, and fin thickness on the thermal performance are studied. The flow field and temperature field on the outside of the fin structure are obtained as a guidance for enhancing heat dissipation effect. Results indicate that the area of rotating elements tend to accumulate heat, where more attention should be paid for a better cooling effect. In addition to this, a moderate increase of fin height, fin pitch and fin thickness has a positive effect on heat transfer enhancement. The peak value of Nusselt number is obtained with a fin height of 7.5 mm, which is about 2.09 times that of the condition without the fin structure. An increase in fin pitch improves both heat transfer performance and comprehensive performance at the same. When fin pitch is 30 mm, Nusselt numberincreases 104% over the original condition.

Using the basic principle of heat transfer, tribology and numerical simulation, a two-dimensional heat transfer model of the three-layer composite brake pair materials were established. The temperature fields of brake pairs during the process of friction were analyzed. Applied given heat loads at different time node on the brake pair model, the temperatures of different bicycle brake pairs were compared and analyzed. Results show that the improved surface structures of brake pair have positive effect on decreasing the temperature of contact areas than that of ordinary surface structure.

The paper is devoted to the analysis of the state of the equipment recycling system in Russia and the issues of improving the legislative framework that accompanies it. The role of state structures in solving the problems of forming a resource-saving ecooriented system for the disposal of decommissioned equipment is reflected. To analyze the work in the field of waste management, to reflect the state of the legislative framework for the existing system of recycling equipment in Russia and abroad, to make recommendations for its improvement. Problems with waste appear when, in the process of production and consumption of substances, objects (equipment), he/she becomes unnecessary for their owners, their owner tries to get rid of this object in the most accessible way. According to numerous information, the disposal of equipment in Russia is mainly carried out (black waste collectors), which control more than 60 % of the scrap of non-ferrous and ferrous metals, so the solution to the problem of creating an effective system for the disposal of equipment becomes not just relevant, but vital for our state. The scientific community in Russia is constantly conducting research on the creation and implementation of a system for the disposal of decommissioned equipment, so, for example, MADI scientists proposed a regional car recycling system for implementation, the scientists of the Federal State Budgetary Educational Institution FNAC VIM also developed a regional system for the disposal of agricultural recycling equipment. In order to quickly solve the problem of working out a general strategy for creating an effective system of recycling equipment in Russia, taking into account the revision of the legislative framework, it is advisable to "run-in" it at the industry level, for example, in the agroindustrial complex, with subsequent replication in other industries.

Important Challenge

Tuberculosis (TB) is a socially significant disease for the entire world community. An important challenge in successfully combating this infection is the avalanche increase in the number of drug-resistant tuberculosis. Currently, among the reasons for the development of pulmonary tuberculosis, a complex of etiological and pathogenic factors contributing to the disruption of the immune response to M. tuberculosis and the formation of secondary immunological failure (SIF) accompanying the disease are of particular importance. However, the issues of discoordination of cellular components of the local immune system of the lungs leading to T-cell deficiency, as well as the ineffectiveness of the B-cell link, reduction of lymphocyte proliferative activity and activation of apoptosis, cytokine imbalance and activation of immunosuppression mechanisms are not fully studied and have a scattered nature, which does not allow us to assess the overall picture of violations. The goal: determining the immunophenotype of lymphocyte population in lung tissue biopsy specimens of patients with various forms of secondary tuberculosis depending on resistance in case fibrosecavernous tuberculosis (FCT). The material in the study was pulmonary tissue fragments of 30 patients with the verified diagnosis of FCT, and distributed in 2 main groups: resistant forms of secondary tuberculosis (n = 15) and 15 patients not resistant forms of secondary tuberculosis. The standard histological method was used. Immunohistochemically panel of markers included CD68, CD4, CD8, CD20, CD138. The study was conducted at the Center for the collective use of scientific equipment «Molecular Biology» of the Medical Academy named after S.I. Georgievsky in the framework of the grant № ВГ 09/2019, supported by federal state autonomous educational institution of higher education «V.I. Vernadsky Crimean Federal University». The results of the study have shown that in the conditions of secondary tuberculosis, regardless of resistance, the formation of local immunodeficiency with an immune response along the Th-2 pathway is determined. The prevalence of cytotoxic lymphocytes in the area of specific granulation tissue and the draining bronchus indicated the prolongation of inflammation and its transfer to the latent phase. The increase in the number of T-helpers and activated plasma cells can serve a reliable prognostic and diagnostic marker for the reactivation of the tuberculosis process.
