Studying at a university is challenging for students, often accompanied by emotional overload. Modern students experience low physical activity levels, which affect their mental performance. Additionally, they tend to experience increased fatigue, and deteriorating cognitive processes, memory, and attention, leading to impaired body functions and weakened immunity. It is crucial to maintain students’ health throughout their university education. A graduate should not only possess solid knowledge but also be in excellent health to support creative endeavors throughout life. To preserve and enhance health, students must be taught how to properly organize their daily routines from the very first days at university. The most important place in the daily routine should be given to physical education and physical activity. Numerous studies have confirmed that physical activity positively affects the entire body’s functional processes, particularly mental performance. During the day, it is essential to alternate between mental and physical activities. A well-structured class schedule, taking into account the dynamics of performance changes throughout the day and week, is also of great importance. This article analyzes changes in mental performance among first-year students during their educational process and offers recommendations to enhance their efficiency.

Lung cancer is one of the most common oncological diseases in the world. The World Health Organization identifies radon as the second most important risk factor for the development of this malignant neoplasm after smoking. The study of DNA repair gene polymorphisms plays a key role in uncovering the mechanisms of radon-induced carcinogenesis.

The aim of this study was to assess whether OGG1 (rs1052133), ERCC1 (rs13181, rs11615, rs3212986), XRCC1 (rs25487), and XRCC3 (rs861539) gene polymorphisms are associated with the risk of radon-induced lung cancer.

As part of the work, a meta-analysis was conducted to study the associations between these genetic polymorphisms and the likelihood of radon-induced lung cancer. Four studies, covering 1,648 patients with radon-induced lung cancer and 1,750 controls, were included in this meta-analysis. The results of the meta-analysis showed no significant association between the development of radon-induced lung cancer and the following polymorphisms: ERCC2 (rs13181), ERCC1 (rs11615), XRCC1 (rs25487).

Statistically significant associations were found for the following genetic polymorphisms: OGG1 (rs1052133) in additive and dominant models; ERCC1 (rs3212986) in a recessive model; XRCC3 (rs861539) in recessive and dominant models. These results indicate a possible association of OGG1 (rs1052133), ERCC1 (rs3212986) and XRCC3 (rs861539) polymorphisms with predisposition to radon-induced lung cancer.

The article defines the effect of various amounts of vermicompost on the growth, productivity and chemical composition of the biomass of Citrullus vulgaris. In the research work, biohumus was used, made with the help of California worms at the educational base of the Aktobe Higher Agrarian and Technical College named after Sh.Bersiev, located in the village of Kenes Nokin, Aktobe region. Watermelons were grown in two different ways, grown with seedlings and seeds in the open ground, after introducing vermicompost into the soil. The results of biometrics have shown that the introduction of vermicompost into the soil has a significant effect on the growth and development of watermelons, the formation of their vegetative biomass, and an increase in yield. The yield of watermelon was observed on the basis of the introduction of vermicompost compared with the average weight of one watermelon by the observer, that is, an increase from 5.5 kg to 7.8 kg of yield was found and amounted to 16.5 kg/m2, which was 5.8; 7.8 and 45.4%, respectively, compared with the control. The content of dry substances, vitamin C and total sugar in watermelon fruits was within the permissible norm and above the control level. During the mass harvest of watermelon fruits, the nitrate content in the product was several times lower than the established norms (MPC for watermelon is 60 mg / kg), that is, the product is environmentally friendly [1].

This article is devoted to the study of the fauna and population structure of small mammals as indicators of the current state of the Polar Ural landscapes. The results of field studies conducted in July 2022 on the coast of Lake Bolshoe Khadatayoganlor, in the floodplain of the Kharbey, Khadata, Malaya Paypudyna, Engayu, Longot'yegan rivers in July-August 2024 and in the floodplain of the Vostochny Nyrdvomenshor stream were analyzed for the paper. In total, 1450 traps (put per a day) and 355 cylinders (used per a day) were worked out, 168 individuals of 9 species of small terrestrial rodents (Rodentia: Clethrionomys (=Myodes) rutilus Pallas, 1779, Craseomys rufocanus Sundevall, 1846, Alexandromys oeconomus Pallas, 1776, Agricola agrestis L., 1761, Lasiopodomys gregalis Pallas, 1779, Alexandromys middendorffi Poljakov, 1881) and insectivores (Eulipotyphla: Sorex tundrensis Merriam, 1900, Sorex caecutiens Laxmann, 1788, Sorex minutus L., 1766) were caught. All the registered species are typical for the Polar Urals and adjacent plain and mountainous regions. Their abundance indices are comparable with the research literature data for the Polar, Subpolar and Northern Urals. The species composition, ecological and faunogenetic structure of the small mammal population correspond to the zonal-subzonal and altitudinal position of the studied landscapes and their biotopic structure. The studied small mammal communities are characterized by low indices of diversity, evenness and stability. Such characteristics are typical for small mammal communities of high-latitude and high-mountain landscapes and are explained by the severe natural and climatic features of the territory. Small mammal communities from the coast of Lake Bolshoe Khadataeganlor, from the floodplain of the Malaya Paypudyna River, from the floodplain of the Vostochny Nyrdvomenshor Stream, which are distinguished by a greater intra-landscape diversity of habitats and a milder microclimate, are characterized by comparatively higher indices of diversity and stability. The studied small mammal communities of the Polar Urals have an undisturbed diversity-evenness structure typical for subarctic landscapes. The studied landscapes do not contain small mammal species with a high degree of anthropogenic adaptability. Along with low integral indices of anthropogenic adaptability and an excess of elastic stability indices over the resistant ones (except for the landscapes at the Morozov Cordon in the floodplain of the Khadata River, where tundra grassing is observed due to musk ox grazing), this indicates, on the one hand, the absence of significant anthropogenic impact on the studied landscapes, and on the other hand, the low adaptability of the studied mammal communities to anthropogenic transformation of the habitat.

This article focuses on examining the main types of natural hazardous phenomena, describes their causes and consequences. It also examines the methods and peculiarities of teaching them in the school geography curriculum, and offers effective methodological approaches aimed at improving students' knowledge.

Natural hazardous phenomena are natural processes that significantly impact the ecological balance on Earth, human life, and economic activities. Their occurrence is related to changes in the Earth's crust, atmosphere, hydrosphere, and biosphere. Earthquakes, volcanic eruptions, storms, floods, mudslides, and landslides are examples of disasters that demonstrate the dynamic nature of natural systems. Some of these phenomena may develop over a long period and can be predicted, while others occur suddenly, leading to large-scale catastrophes.

Currently, the frequency and intensity of natural disasters are increasing. According to scientists' research, climate change, urbanization, deforestation, and anthropogenic impacts on ecosystems contribute to the intensification of these phenomena. Therefore, education about natural hazards is one of the key tasks of the school geography curriculum. It is important to provide students with a comprehensive understanding of the causes, distribution areas, impact on humanity, and preventive measures for natural hazards.

Through the geography course, students not only acquire theoretical knowledge but also develop safety culture, learn to work with maps, and study methods of preventing natural disasters and protecting from them. During lessons, real-life examples of natural disasters are discussed, their consequences are analyzed, and prevention strategies are examined. This helps students to scientifically understand natural phenomena and encourages them to take responsibility for the environment.

The article offers innovative circuit engineering solutions in the field of electric vehicles. The existing electrical and functional circuits of electric cars imply the presence of expensive electronic components, both in the control unit and in the wireless charging unit. An analysis of existing low- and medium-weight electric cars suggests that existing electronic circuits can be upgraded by replacing expensive elements with more affordable electronic components.

In particular, it is proposed to introduce the STM32 microcontroller into the control and charging system of electric cars, which is actively used in technical projects of small and medium complexity. It is also acceptable to control a low-mass electric car using KYL-300L radio modules operating in the megahertz range.

The electrical structural schemes proposed in the study will make it possible to implement simplified circuit design solutions for small and medium-weight electric cars. In the future, the authors plan to create a mock-up of a small electric car based on the proposed schemes.

The article considers the names of objects necessities used in people's daily lives within the framework of an onomastic ethnochrematonym. The author claims that, although the names of objects of material culture have not yet been studied in Kazakh onomastics as a noun сhrematonym. The world of chrematonyms is one of the main semantic features and concepts characterizing various inherent properties and features of the names of household items used in the everyday life or profession of people who lived in this environment. Concrete examples show that the names of the necessary products are words that have an impact on the formation and development of the Kazakh ethnonym, including regional tribes. In the life of modern society, scientific and information resources have substantiated and proposed ways to determine the existing functions and semantic features of words recognized by ethnochrematonyms, with the opinion of research scientists dealing with this problem.

The article considers that the chrematonym should be studied within the framework of the poetonym of onomastics (stylistic rhythm and emotionally expressive essence, etc.).
