The paper presents the results of a study examining the practices of using medicinal plants (chamomile, wormwood, dog rose, and hawthorn) among the population of the Chuvash Republic, as well as an assessment of respondents’ attitudes towards the independent harvesting of herbal raw materials and towards pharmaceutical forms. The aim of the study was to test the hypothesis that there is a high level of public trust in the healing properties of traditional medicinal plants and to identify the reasons for preferring purchased raw materials over self‑collected ones. The empirical part included an...

This study presents a comparative analysis of how sucrose (C 12 ​ H 22 ​ O 11 ​ ) concentration affects aqueous solution density, interpreting the data through biochemical and physical‑chemical mechanisms (hydration, hydrogen‑bond network rearrangement, osmotic effects); a direct correlation between sucrose concentration and density was confirmed, with the maximum density increase (1.280 g/cm³) observed at a 44.4 % mass fraction, reflecting solution structure compaction due to intermolecular interactions, and supporting the use of the areometric method for rapid carbohydrate concentratio...

The paper presents the results of a study on the physicochemical properties of water and their role in natural and biological systems. An analysis of the water molecule structure was carried out, and its key characteristics — high heat capacity and selective dissolving power — were demonstrated experimentally. The significance of these properties for stabilizing the environment and supporting vital functions was also assessed. The aim of the study was to demonstrate the fundamental importance of water’s anomalous properties, which are often perceived as commonplace. The results confirm that th...

This study presents the results of a comparative analysis of the effects of acoustic stimuli on the psychophysiological state of domestic animals (dogs and cats). An experimental assessment was carried out of behavioral and physiological indicators — including rest/sleep duration, heart rate, and relaxation index — under the influence of various music genres and species‑specific compositions. The aim of the research was to test the hypothesis regarding the species‑specific nature of animal responses to music, depending on its acoustic parameters (tempo, frequency spectrum, and harmonic structu...

This study presents the results of a comparative analysis of the prevalence of vision defects and risk factors among students, as well as an experimental assessment of key parameters of the visual apparatus — the near point of clear vision and the area of the blind spot. The aim of the research was to evaluate the impact of increased visual load from digital devices on the visual health of young people and to test the effectiveness of simple physiological tests for the rapid assessment of certain visual functions. The practical component included a sociological survey of students and a series...
