Project of building: solar hot water
Статья научная
The rapid development of urbanization in China has led to an increase in high-rise residential buildings, leading to a surge in the construction industry. However, this prosperity has brought about a significant increase in energy consumption, prompting people's demand for alternative energy. As a solution to this problem, solar hot water systems are becoming increasingly popular in China. The following contents need to be considered in the design of solar hot water systems. The general solar hot water system consists of solar collectors, solar water distribution pipes and water storage tanks. The arrangement of the water storage tank and the water distribution pipe is matched with the design of the building, which has great influence on the operation of the solar energy in the building. With the rapid increase in building height and the increase in residents, the roof area has not changed. The architectural layout will have an impact on the absorption performance of solar radiation. Therefore, in order to optimize the use of solar energy, regional planning should be considered. Different solar radiant intensity and different locations of solar collectors will lead to different collection efficiency and hot water supply conditions of solar water heating systems. Throughout the entire process of architectural design, the application of solar energy technology in buildings also requires consideration of the operating area conditions and architectural style, in harmony with the architectural style.

Among the alternative energy sources, of particular importance is hydrogen energy, which is likely to address the acute environmental problem of large cities in the near future, in terms of pollution of the environment, first of all, of air pollution from vehicles. Among hydrogen-containing raw materials, which can be used in a fuel component, hydrogen sulphide is of particular importance. It is well-known that the Black Sea the largest basin on the planet by the amounts of hydrogen sulphide dissolved in water. In that regard, the Black Sea is the object of the attention of scientists, since its deep waters contain hydrogen sulphide, hydrosuphide and suphide ions in large quantities. The sources of their origin are gases erupted from the volcanic and geological splits existing at the bottom of the sea, as well as organic substances and products of decomposition of microorganisms brought down by the rivers. In this regard, the Black sea may become a potential source of hydrogen energy, and simultaneously that may improve environmental situation in the Black Sea. The paper analyzes the challenges existing in the use of hydrogen obtained from hydrogen sulphide of the Black Sea, as an alternative fuel in the internal combustion engines of vehicles, as well as the prospects for addressing these challenges.

Prospects of soft fresh cheese production in Kazakhstan
Статья научная
In this article, the relevance of increasing the production of cheeses on the domestic market of the Republic of Kazakhstan is shown. In accordance with changes in the structure of the population’s nutrition and protein deficit, increasing attention is being paid to increasing the use of protein resources for food purposes, including the creation of new products. According to the Food and Agriculture Organization of the United Nations, the volume of world cheese production is constantly increasing. When polling the population in recent years it became clear that the cheese-curd market is waiting for the local producer. Therefore, the concept of development of low-cost cheeses remains to be topical - with high yield and accelerated maturation periods, which will be analogues of import-brand brands. The advantages of organizing the production of soft fresh cream cheese and cheese products of this type for domestic cheesemakers lie on the surface: this is a relatively new product for our market, soft cheeses have an extremely high yield, which makes their products very cost-effective, and this kind of cheese now has steady and constantly growing demand. The difference between fresh soft cheeses is that they are not pressed in production, the dairy raw material is gentle heat treatment, thanks to which useful substances remain intact in cheese. Proceeding from this, it can be concluded that the innovations and increase in the production of soft fresh cheese are real and possible and necessary.

PsbS Dependence in Lipid and Pigment Composition in Rice Plants
Статья научная
Plants acclimate to fluctuations in light conditions by adjusting their photosynthetic apparatus. When the light intensity exceeds, an unbalanced excitation of the two photosystems occurs. It results in reduced photosynthetic efficiency. Photosystem II (PSII) is the most susceptible and dynamically regulated part of the light reactions in the thylakoid membrane. Non-photochemical quenching of chlorophyll fluorescence (NPQ) is one of the short-term photoprotective mechanisms, which consist of the number of components. The strongest NPQ component — qE is localized in the PSII antenna and induced in plants by lumen acidification, the activation of the pH sensor PsbS, and the conversion of the violaxanthin to zeaxanthin within the xanthophyll cycle. Here, I present data that characterizes the role of the PsbS protein in organization of PSII structural components in isolated PSII-enriched membranes. The preparations were isolated from wild-type (WT) and PsbS-less (PsbS-KO) mutant rice plant. Based on the obtained results, the PSII-enriched membranes from WT and PsbS-KO differ as in the level of lipids, also in carotenoids. I conclude that the PsbS-dependent changes in membrane fluidity in PsbS-KO mutant plants compensated with increased lipid level in mutant plants.

Psycholinguistic features in advertising discourse: understanding the cognitive
Статья научная
Advertising discourse is a powerful tool employed by marketers to persuade consumers and drive purchasing behavior. Understanding the psycholinguistic features embedded within advertising messages is crucial for comprehending how these messages influence consumers' cognitive processes and decision-making. This article explores the intricate relationship between psycholinguistics and advertising discourse, shedding light on the cognitive mechanisms that underpin persuasion in marketing communications. Drawing on theoretical frameworks from psycholinguistics, cognitive psychology, and marketing, we examine how linguistic elements such as language choice, rhetorical devices, and semantic priming impact consumers' perception, comprehension, and evaluation of advertisements. Additionally, we discuss the role of psychological principles such as cognitive fluency, persuasion techniques, and emotional appeals in shaping advertising discourse. By elucidating the interplay between language, cognition, and persuasion, this article contributes to a deeper understanding of the mechanisms driving consumer behavior in the context of advertising.
