The habitats with a high number of mountain sheep include the Karaganda, Turkestan, Dzhambul and Almaty regions of the Republic of Kazakhstan. The paper aims to estimate the changes in argali’s number and reveal the basic influencing factors. The total number of wild mountain sheep in Kazakhstan is 17954 heads. The paper shows that the share of the influence of environmental and anthropogenic factors on the number of argalis is 99.7%. The main influence on the number of snow sheep is exerted by anthropogenic factors such as poaching and economic use of the range of wild mountain sheep by humans. From time to time, severe fires affect the deterioration of the habitat. The authors attribute the creation of specially protected natural territories and the inclusion of subspecies in the Red Book of Kazakhstan to the positive impact of human activity on the argali population. In modern conditions, the natural potential viability and survival of mountain sheep and further naturalization are weak, although there is an increase in the number of argalis. These aspects indicate that the anthropogenic factor affects animals intensely. The analysis of variance shows and testifies to the high influence of the anthropogenic factor on the number of argalis in regions of Kazakhstan. Today, to improve the protection of mountain sheep, it is advisable to organize a network of specially protected natural territories in the mountainous regions of the south and south-east of Kazakhstan.","PeriodicalId":21854,"journal":{"name":"Siberian Journal of Life Sciences and Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49557861","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}

In this regard, the rapid development of new drugs and methods, as well as modification of existing methods in order to increase their effectiveness, is currently required. The paper aims to develop and study two promising agents for photodynamic therapy. We discussed a new binary complex based on the widely used photosensitizer chlorin E6 with europium, which can solve one of the main disadvantages of drugs for photodynamic therapy: it can be used to treat deeper tumors and act more effectively by transferring luminescence energy between europium and chlorin E6. Our other agent was copper-containing chlorophyllin. Chlorophyllin is a natural component, which is always promising in the development of new drugs. The optical and fluorescent parameters of the agents were determined using physicochemical methods; their ability to generate reactive oxygen species in the presence of two fluorescent probes was studied: 2ʹ, 7ʹ-dichlorodihydrofluorescein and dihydrofluorescein. Thus, we showed the effectiveness of chlorophyllin in comparison with chlorin E6 by 1.92 times at 50 μg / ml E6 and showed the effectiveness of the binary complex even at the minimum concentration of 10 μg / ml.

The macrofossil analysis and the degree of peat decomposition were studied by the microscopic method, the moisture content and the dry bulk density were studied by the gravimetric method. The ash content was determined by burning, the content of organic matter was calculated by the difference between the mass of dry peat and the ash content. The carbon content (%) in peat samples was calculated based on the dry bulk density, the organic matter content and the mass fraction of carbon for each volume of peat. The rate of vertical growth of peat and intensity of peat accumulation in periods of Holocene were calculated based on the results of radioactive dating. \u0000The parameters of surrounding landscapes during the mire genesis were characterized by the results of the palynology analysis and the estimation of fire activity. The intensity of fires in paleolandscapes was studied by the content of coal particles in each (1 cm3) sample of wet peat. \u0000Results. The genesis of the Podkosmovo mire is presented by 5 stages which were took place under the stable conditions of water-mineral nutrition. The carbon accumulation in the genesis proceeded at the rate of 45.7 g/m2/year on average. At the same time, the surrounding landscapes differed in the degree of afforestation and the intensity of anthropogenic press. \u0000Conclusion. The moderate hydration and nutrition with mineralized waters ensure the stability of the mire development and the intensity of carbon accumulation, despite the change of surrounding landscapes under the influence of climate or human. However, the active transformation of the surrounding landscapes can have a negative impact on the functioning of the mire and reduce the intensity of carbon accumulation.","PeriodicalId":21854,"journal":{"name":"Siberian Journal of Life Sciences and Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42527325","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}

One of the most pressing problems in the world is the production of food protein. The global protein deficit is estimated at 30 million tons per year, for the Russian Federation it is estimated at 2-2.5 million tons of protein per year. \u0000The problem of protein deficit can be partially solved with the help of methanotrophic bacteria. Under optimal conditions, methanotrophic bacteria are able to oxidise actively natural gas – methane and increase their biomass, rich in valuable protein, vitamins and other biologically active substances. The feed product from methanotrophic bacteria is comparable to fish meal and soybean meal, the concentration of pure protein in it is more than 80%. \u0000Purpose. Isolation of methanotrophic bacteria from natural biocenoses and their cultivation on various nutrient media in laboratory conditions. \u0000Materials and Methods. The study was conducted from 2019 to 2022 in the microbiological laboratory of the Center for Technological Excellence “Advanced Chemical and Biotechnology” of the Tolstoy Tula State Pedagogical University. The object of the study was methanotrophic bacteria isolated from various natural and artificial ecosystems, collection strains of Methylococcus capsulatus B-2990 and Methylomonas methanica B-2110. To isolate methanotrophic bacteria, the method of seeding a accumulative culture on a solid agiarized sterile nutrient medium in Petri dishes was used. For the cultivation of methanotrophs, nutrient media of various compositions containing all the necessary macro- and microelements for the normal growth of bacterial colonies were used. \u0000Results. Colonies of methanotrophic bacteria were found in one sample of bottom sediments taken from the sphagnum swamp of the village of Kochaki in the Tula region and in samples from a methane reactor. As a result of comparison of nutrient media for isolation and cultivation of methanotrophs, it was found that the most suitable medium for isolation of methanotrophic bacteria is the standard nitrate mineral medium NMS. For the cultivation of methanotrophic bacteria, the best media were: the nutrient medium with the addition of anaerobic sludge, the ammonium mineral nutrient medium (AMS), and AMS with addition of methanol, the nutrient medium No.221 with addition of methanol. \u0000Conclusions. The use of various nutrient media for the cultivation of methanotrophic bacteria makes it possible to assess the effect of various organic substances on the growth and development of bacterial colonies. The study of various natural and artificial ecosystems makes it possible to expand taxonomic knowledge about this group of microorganisms, as well as to increase the potential of using methanotrophs in solving various problems of ecology and biotechnology.","PeriodicalId":21854,"journal":{"name":"Siberian Journal of Life Sciences and Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47999849","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}

To determine the character accentuations, the following were used: Leonhard’s questionnaire and the method of identification characterological verbal portraits – E.G. Eidemiller. To compare the groups, correlation analysis was used (Mann-Whitney U test). \u0000Results. Within group of adolescents with diabetes, the sensitive (40%) and schizoid (30%) types of accentuation prevail, while in healthy adolescents, the hyperthymic (55%) type of accentuation prevails. Adolescents with diabetes were more conflicted and less capable of self-control than a group of adolescents without a diagnosis. On average, accentuations were more pronounced in healthy adolescents, the average scores for each of the accentuations in patients with diabetes mellitus were lower. Also, the correlation coefficients between the indicators of the K. Leonhard method and the indicators of the E.G. Eidemiller method on samples of adolescents with and without a diagnosis of diabetes mellitus turned out to be different. In the group of adolescents with diabetes mellitus, correlations were observed between the following parameters: “emotive type” and “neurasthenic type” (r=0.81, p=0.05), “anxious type” and “paranoid type” (r=0.65, p=0.05), “excitable type” and “unstable type” (r=0.65, p=0.05).

As it is on its success that the provision and condition of food security of the country directly depends. Food security is very urgent, especially during the current financial crisis. \u0000To date, the instability of agriculture in Kazakhstan is the main reason for the low level of food security in the country. One of the strategic tasks for Kazakhstan is to ensure food security. There is a lack of scientific research aimed at financing and state support of agriculture as an important prerequisite for ensuring food security in Kazakhstan under the conditions of the Eurasian Economic Union, which determines the purpose of our study. \u0000The following research methods were used in the work: economic and statistical; economic and mathematical methods, including methods of statistical analysis. We use correlation and regression analysis to study the relationship between public financing of the agro-industrial complex and food security. By this we not only analyze the current situation, but also make it possible to implement a medium-term forecast. \u0000The result of the study is a structural analysis of the financing of the agro-industrial complex, which shows that the bulk of the financing is carried out by own funds, and the amount of public investment is less than own resources. Based on the study, the dependence of agriculture in Kazakhstan under the EAEU conditions on state funding and support has been revealed. The main ways and solutions to ensure food security of Kazakhstan in the conditions of the Eurasian Economic Union have been proposed. \u0000Conclusions. Ensuring food security of the population is an integral part of economic, political and national security of the country. In this context, the agro-industrial complex is the main key factor and epicentre of food security of the country, and without state financial support for agriculture, food security of Kazakhstan is and will be under threat. Only by solving this urgent problem can Kazakhstan lead among the member countries of the Eurasian Economic Union.
