The study is dedicated to the assessment of fish fauna of the natural and artificial water bodies in Nakhchivan in 2018-2022 and the environmental factors that have impact over them. It was determined for this period that fish fauna is distributed in 10 water bodies. Out of those water bodies, Nakhchivan reservoir dominates both from the perspective of species and fish hunting. Along with the study of fish fauna in aquifers, the factors influencing their development were also assessed. Although the balance is disturbed as a natural factor, factors such as industrial waste, garbage and solid waste, sewage waste, detergents and artificial fertilizers, agrochemicals, oil and oil products, radioactivity and thermal pollution are the main factors of environmental pollution. Other factors: untimely and excessive hunting, fishing during reproductive migration, the introduction of new fish species into freshwater sources, anthropogenic factors such as hydropower also have a significant impact on fish development.

The article discusses the effects of different tillage methods, predecessors, and mineral fertilizers on the soil bulk density and soil moisture content of light-gray-brown soils at the rainfed condition. The results of the research conducted during the years 2014-2017 under cereal crops reveal that the soil bulk density and soil moisture content exhibit dynamic changes within the vegetation period, depending on the tillage method, the growth stages of the crops and other factor. Furthermore, there is differentiation in the moisture content and soil bulk density between the topsoil and the subsoil layer. During the research period moisture content varies depending on precipitation, crop growth stages, predecessors. Optimum moisture level is observed within periods of relatively higher precipitation and intensive growth stage of crops. Soil bulk density has varied within the range of 0.97-1.53 g/cm³. Favorable physical condition has been observed under the conventional and minimum tillage. Based on the research findings, the bulk density and moisture content of light-gray-brown arable soils can be assessed satisfactory through relevant quantitative indicators.

В статье говорится об употреблении понятия avaritia «жадность» в сочинениях Цицерона. Целью исследования является системный анализ понятия на основе квантитативного метода. Имеется более 150 случаев употребления понятия avaritia и его производных (avarus, avare) у Цицерона. Чаще всего термин встречается в речах (около 100 раз), особенно в инвективах «Против Верреса» (55 раз), меньше всего - в переписке (6 раз). Для Цицерона жадность - один из самых серьезных пороков, подразумевающий преувеличенное мнение о деньгах. Наряду с отрицательными нравственными категориями (luxuria / luxuries, crudelitas, superbia и др.) и положительными (этическими понятиями стоической философии (honestum / honestas, virtus, officium, justitia, liberalitas, cogitatio, temperantia и др.) и исконно римскими этическими и политико-правовыми терминами (dignitas, jus, lex и др.), противопоставленными алчности) понятие avaritia образует ядро этико-философского и политического понятийного аппарата сочинений Цицерона.

The possibility of preventing salmonellosis in chicken (pathogen agent - Salmonella enterica , serovar Enteritidis (SE)) by using specific yolk IgY was discussed in presented article. There has been raising the number of reports in the scientific periodicals about increased antibiotic resistance of Salmonella . SE is one of the most common Salmonella serovars worldwide that causes food poisoning in humans. At the same time, infected chicken eggs and meat serve as the main source of infection. For extraction of the IgY, 10 laying hens were used. All layers were hyperimmunized by a vaccine containing live attenuated strains of Salmonella enterica , ser. Enteritidis and Salmonella gallinarum Pullorum. The control group with the same number of layers was not vaccinated. A feed additive for newly hatched chicken and solution with purified and isolated IgY were prepared from egg yolks of immunized and non-immunized birds. During oral administration as a feed additive in per os and intraperitoneal experimental infection by a lethal dose of SE the examination of the efficiency of the obtained product on six-day-old chickens were conducted. Thereby, conducted examinations have shown the high efficiency of the feed additive and preparation with purified immunoglobulins prepared from the yolks of eggs of immunized chicken in experimental infection with a lethal dose of Salmonella Enteritidis.

Basic principles of the mechanism of ensuring social and economic security
Статья научная
The choice of the hierarchical principle of the structural organization of the mechanism of ensuring socio-economic security is consistent with the presentation of the role of its components in the regulation of financial and economic processes. Thus, in the performance of the functions of defence, the role of the components of the mechanism in the schemes of direct and current relations, information channels, management conclusions and administrative work is inevitable. Apart from this, the inter-element relations of the mechanism of ensuring social and economic security are mediated by financial and economic relations and, first of all, commodity-money, which is based on the coordination and specific subordination of financial and economic interests. This means that the process of ensuring social and economic security must not be strictly subordinate to the hierarchy of public administration, and be one of its intensive components, which plays a dual role. On the one hand, it has the ability to be needed as the 1st of the methods of implementation of the state financial and economic interests...

Big data analytics and ethical responsibility in the digital age
Статья научная
Big data analytics possesses the capability to process vast volumes of digital content and analyze societal sentiment trends in real time. Such analyses offer comprehensive insights and detailed models on how social awareness forms and evolves, particularly during periods of crisis. However, due to the immense, diverse, and complex nature of these datasets, traditional analytical methods often fall short, necessitating the ongoing development of novel interdisciplinary approaches and methodologies. At the same time, significant debates continue regarding the extent to which these datasets accurately represent the real world, given the existence of the digital divide and the ethical frameworks governing the collection and application of big data. This article explores the theoretical and methodological foundations of big data-driven research, the societal impacts arising from inequalities in data access, and the ethical issues that emerge during the collection and analysis of extensive datasets. The study consists primarily of secondary data obtained from existing literature, case studies, and the application of big data analytics in various research fields.

Biodiversity of ravine flora of the northeastern part of the Lesser Caucasus
Статья научная
As a result of the study of the areas, the geographical features of the ravine flora were studied. The flora is grouped by geographical elements according to the existing scheme of geographical elements. Geographical analysis shows that pontic and nemoral geoelements are dominated by Eurasian, European, and ancient Mediterranean areas. Nemoral and pontic geoelements cover all areal types. Cosmopolitans dominate. It should be pointed out that as a result of human economic activity, the species composition in the ravines has decreased sharply. Ravines occupy an important place in the formation of the vegetation of the north-east of the Lesser Caucasus and play the role of soil protection and water protection. Systematic, biomorphological, ecological cenotic, geographical analysis shows that the ravine flora is similar to the zonal flora of the meadow steppe system, but at the same time has its own characteristics. It is heterogeneous in species composition. One of the peculiarities of the flora is the predominance of weeds, forest vegetation and migrants.
