The minimum, maximum and average temperatures in the cave during the wintering period of R. mehelyi are equal: 6.9 oC, 15.6 oC and 12.4 oC accordingly. The minimum humidity was 89.1 %, the maximum was 98.2 % and the average was 92.7 %. It was found that the temperature inside the shelter affects the number of individuals in the visible part of the cave and the formation of individual groupings. In addition, there is an increase in the number of individuals in April before the start of migration.It was found that humidity does not affect the movement of the species inside the cave, but temperature is a factor determining the movement of animals and their crowding. Thus, to accurately record the number of species, which is important for carrying out environmental measures, it is necessary to take into account both indicators – temperature and time of research.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"7 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140732794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetic analysis of HCVs revealed partial clustering within subtypes 1a and 3a on a territorial basis. HCV subtypes 1b, 2a and 2k were grouped with other HCVs previously isolated in Russia, Armenia and Kyrgyzstan. Among the HCVs studied, no clusters were found that were common to HIV‐infected individuals with the same route of infection. Among patients who had no experience of taking DAAs, HCV resistance mutations in the NS5A region were found in 42,3 % of cases for those infected with subtype 3a virus and in 75,6 % of cases for those infected with HCV subtype 1b.The analysis of the diversity and occurrence of mutations of HCV drug resistance to direct antiviral drugs is extremely important for the development of tactics for effective treatment of CHC. The high prevalence of polymorphic mutations that affect sensitivity to DAAs indicates the relevance of introducing HCV resistance analysis into clinical practice.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"53 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140733603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relevance of the study lies in the fact that achieving the main parameters of the declared green economic course is impossible without the use of the most progressive forms, methods and instruments of financial support for environmental projects. The purpose of the work is to study the theoretical aspects of financial support for environmental projects in the Russian Federation, contributing to the transition to a green economic course and increasing efficiency in the implementation of these projects.When conducting the study, general scientific methods of cognition were used: – dialectical materialism, inspection observation; methods of economic and statistical analysis, comparison and generalization were used to generalise domestic and foreign experience in the financial support of environmental projects.Having studied the features of financial support for the green economy, the team of authors concluded that there is a predominance of state financing of investment projects in the field of ecology, while the mechanism of public‐private partnership in fact does not function at the proper level and private investments in environmental projects are unattractive from the standpoint of profitability and profitability. Currently, the volume of financing for the transition to the “green deal” is at the level of 20–25% of the required need for the implementation of an ambitious project: in this regard it is necessary to search for ways aimed at increasing the efficiency of financing the green economy.The authors studied the features of financial support for environmental projects in the green economy. Financing problems are identified and recommendations for solving them are given.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"8 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140732827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is also based on the application of methods of comparison and contrast, grouping, historical and factor analysis.The key role of the state in the creation and effective functioning of the integrated system of solid municipal waste management (MSWM) is determined by the ability to concentrate the necessary financial resources and guarantee uniform standards and requirements for system participants to achieve the stated goals of the closed cycle economy (CCE). Uniform standards and requirements for system participants must be guaranteed to achieve the stated objectives of the closed cycle economy (CCE). This is confirmed by the results of the financing of the TCO management system for 2019–2023, when the federal budget financed activities to the amount of 42.3 billion rubles. For the purposes of the federal EZC project, 8.6 billion rubles were allocated. It is important to ensure off‐budget financing of these activities and modernization of domestic enterprises, for which the use of secondary raw materials is available and economically feasible. The priority of measures to implement CCE in the Russian Federation is financial support for the creation and development of infrastructure for waste collection and recycling.The processes on improvement of the regulatory and legal framework and personnel training are related to the need to implement a \"top‐down\" approach, which determines the centralisation of decision‐making and the efficiency of attracting extrabudgetary funds dominating in the financial support of the functioning of the TCO management system and implementation of CCE.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"58 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140733355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
