Agrochemical characterization of podzolic-yellow soils fertilized for a long time
Статья научная
It is known from our research that in the last 40-50 years, as a result of intensive use of podzol-yellow soils, the reserve and amount of humus reduced, mechanical composition relatively lightened, but relatively stabilization was observed in humus quantity in the areas where the crop rotation was available. It is known that among the agricultural plants, the standard soil for tea plant - weakly podzolic yellow soil has a score of 100 points on the quality scale. Every year application of mineral fertilizers is required in order to get a lot of green leaf crops from the tea plant bushes in terms of soil-ecological requirements. Therefore, physiological acid ammonium-sulfate fertilizer is applied to bushes at a high dose every year. The super-phosphate fertilizer with more gazh in its composition is applied together with nitrogen fertilizer in order to increase its efficiency. In addition to it, potassium-chlorine or potassium-sulfate is applied. According to the research results it can be noted that humus of moderately washed sort decreased 0,1-1,30%, total nitrogen - 0,07-0,08%, absorbed ammoniac - 20,60-40,14 mg/kg, ammoniac dissolved in water - 1,56-4,38 mg/kg, nitrate - 0,24-2,34 mg/kg, total phosphorus - 0,04-0,05%, gross phosphorus - 2,28-23,54 mg/kg, total potassium - 0,14-0,80 %, exchangeable potassium - 50,0-77,4 mg/kg compared to non-degraded sort.

According to the article, grasslands amount for 103,816 hectares out of 5,502.78 km2 total area of Nakhchivan AR. The grasslands play a vital role in the development of livestock, especially rearing of bovine animals, small-horned livestock and beekeeping. Descriptive research work has been conducted in the field, in order to determine the role of grasslands in the development of livestock farming. There is a strong need for conducting study of the area on the basis of landscape planning. As a consequence of a series of natural and anthropogenic factors, a number of environmental issues have arisen on grasslands, and as a result, some areas have become unusable. 58,020 hectares or more than 50% of grasslands became unusable. On the other hand, 45,796 hectares are in good condition. It should be outlined that since destructive factors outpower restorative factors, there is a risk of losing grasslands in the future. It is about time to seriously engage in the solution of environmental problems related to grasslands. Otherwise, we will face bitter consequences. Therefore, landscape planning should be applied in every research work. Hierarchical landscape composition of the area and the problems in each composition should be clearly defined, and the solutions should be developed accordingly. Research work is notably topical in this context.

Allergic reactions during anesthesia and their management
Статья научная
Allergic reactions during anesthesia, although relatively rare, represent one of the most critical emergencies in the operating room. This review highlights the main triggers, clinical signs, and evidence-based strategies for diagnosis and management of perioperative allergic reactions. Recent literature (2010-2024) was analyzed, focusing on epidemiology, risk factors, and management guidelines. Six widely cited studies and international recommendations were included. Neuromuscular blocking agents, antibiotics, and latex remain the leading causes. Clinical manifestations range from mild urticaria to life-threatening anaphylaxis. Serum tryptase levels and postoperative allergy testing are essential for confirmation. Prompt administration of epinephrine, airway support, and fluid resuscitation remain the gold standard for treatment. Early recognition and rapid intervention are crucial for survival. Standardized management protocols, preoperative allergy screening, and postoperative follow-up significantly reduce morbidity and mortality associated with allergic reactions during anesthesia.

Alternative analysis: the prime numbers theory and an extension of the real numbers set
Статья научная
Here we consider the theory of prime numbers at a new methodology. The theory of prime numbers is one of the most ancient mathematical branches. We found an estimate of the all prime numbers sum using the notions of infinite lager numbers and infinitely small numbers, farther we estimated the value of the maximal prime number. We proved that Hardy-Littlewood Hypothesis has the positive decision too. The infinite small numbers define a new methodology of the well-known function o(x) application. We use the sets of the theory of prime numbers and infinitely small numbers with a linear function to formulate the alternative extension of the real numbers set.

Amelioration State of Soils at the Mouth of the Kur River
Статья научная
The analysis of the melioration state of soils at the mouth of the Kura River in the Salyan district was carried out in 2019-2024. The territory is mainly covered with gray-brown, gray, gray-meadow, meadow and meadow-marsh soils. In all areas of cotton and grain crop cultivation, the soils are saline and solonchakous to varying degrees, crusted, swamped, etc. Regardless of the depth of groundwater, there are various types of salinization depending on the agrochemical composition of the soils. In the territory through which the Kura River flows, there is an inappropriate use of its waters, discharge of industrial and domestic wastewater into the river. This is manifested to a greater extent at the mouth of the Kura River, causing floods that pose a threat to the population living here, and creating environmental problems in the marine area. A detailed study of environmental violations at the mouth of the Kura River is relevant. The existing hydrological condition has been analyzed, the causes of melioration problems have been determined, and recommendations have been proposed. The results obtained serve the development of sustainable agriculture and long-term conservation of soil resources in the region.

The study of the process of migration in aphids has great practical importance. Thus, the aphids pass from one plant to another by these morphs and feed there and maintain their population by growing. The literature information on the research of the photoperiodic reactions in aphids is sufficient. However, the seasonal adaptation characteristics of sugar beet aphids have not been studied up to date in Azerbaijan. For this reason, the study of an impact of photoperiod on the emergence of winged ones in the population of black bean aphid is one of the important issues. During the study of reaction of individuals fed in the same routine against the photoperiod in the next generations, it has been defined that short photoperiod is more observed in the following generations. It seems that the information collected from the former generations is directly passed to the next generations. The results show that the continuous breeding of these species by means of parthenogenesis is only available in the long day (14, 16, 18, 24 hours) routine. However, the winged individuals prevail in the short photoperiods. The preference of winged individuals in 24 hours of photoperiod rather than others (14-18 hours) is probably related to the physiological changes occurs in them.

The age and seasonal dynamics of goat infestation with parasites of the genus Eimeria in the Nakhchivan Autonomous Republic are analyzed. Observations conducted on farms in the Republic revealed that the highest level of infestation with Eimeria was recorded in the autumn months (51.4%), while the lowest was in the summer season (15.0%). Six species were recorded in the winter, spring, and autumn seasons, while only three species (E. absheronica, E. yolchijevi, and E. ninakohlyakimovae) were recorded in the summer season. The increase in the number of infestations in the autumn months is mainly due to humid and mild weather, as well as the fact that animals are kept indoors for certain periods. Under these conditions, increased contact between animals accelerates the transmission of infection. At the same time, moderate temperatures and humidity create favorable conditions for the formation of spores and the development of Eimeria oocysts in the external environment. The decline in infection rates during the summer months is explained by goats grazing more on open pastures and frequently changing grazing locations. Exposure to sunlight, especially ultraviolet radiation, high temperatures, and dry soil, leads to the destruction of oocysts, reducing the intensity of infection. It has also been established that young goats are more susceptible to eimeriosis, and the infection rate decreases with age.

This article investigates the application of digital methods to literary texts, focusing on a comparative analysis of Chingiz Aitmatov's work Samanchynyn zholu (Mother Earth) and its English translation. Recognizing the growing importance of digital humanities in advancing textual research, the aim of this article is to assess the translation's quality and explore the efficacy of Voyant Tools for analyzing texts in the Kyrgyz language, marking one of the first such attempts. Comparative analysis and Voyant Tools' functionalities, including word frequency calculation, collocation identification, and visualization (word clouds, graphs, concordances), the study processed both the 27,161-word Kyrgyz original and the 38,737-word English translation. Key findings reveal thematic alignment between the two texts; characters like Aliman and Tolgonai, and themes such as "Mother Earth," war, and daily life, consistently emerged as central. Despite linguistic structural differences, the translation effectively conveyed the core narrative and character prominence. While minor variations in lemmatization across languages were observed, Voyant Tools successfully provided quantitative and qualitative insights into textual characteristics and semantic preservation. This research demonstrates the robust potential of digital tools to complement traditional literary scholarship, offering a data-driven approach to understanding translation fidelity and enriching the study of Kyrgyz literature.

Analysis of curricula in terms of tolerance education of young school-age children
Статья научная
The subject programs of elementary school are analyzed in the context of tolerance education in children. The analysis criteria were the tasks of developing tolerance in junior schoolchildren and the ways (mechanisms) we identified for solving these problems. Professionally, a fully organized pedagogical process consists not only of didactic but also of educational foundations, which purposefully involves the organization of the classroom and extracurricular educational work. According to the authors, the main task of the school is to cultivate a sense of national identity, pride, honor and dignity in the younger generation. Only in the process of formation of the pupil's personality, some conditions of tolerance and separate ways of their realization were reflected in a superficial form.
