The aim of the study was to determine the influence of various drinking liquids on an the dentoalveolar system in rats. The study was carried out on 25 white male rats from the nursery of Krolinfo branch of the Moscow region which were kept in standard vivarium conditions. Age of rats-3-6 months, weight - 150-200 grams. The study was carried out in accordance with the ethical principles of humane treatment of animals, in accordance with the current legislation of the Russian Federation. To assess the effect of consumed fluids, groups of 5 animals of the same sex (males, females) were used. The animals were randomly assigned to groups. Observation of animals was carried out for 6 months, during this period the animals were in conditions of free access to food and as drink received the studied liquids ad libitum. Experimental groups within 3 months received the following types of drink: I (control group) - tap water; The II group - Coca-Cola; The III group - honey water; The IV group - the distilled water; The V group - light water. The results obtained by the authors and the data provided in literature confirm that among the factors that affect the teeth condition, in particular the characteristics of the hardness of enamel and dentin, the use of various sugar-containing drinks, as well as the duration, quantity, and frequency of their use, can play a significant role. These factors remain largely unexplored at present. It is obvious that in order to stop caries, it is necessary to develop and carry out a set of preventive measures, including limiting the consumption of sweets and beverages containing sugar, along with regular dental care and a balanced diet.

The European pond turtle (Emys orbicularis) is a wide-ranging, long-living freshwater species with low reproductive success, mainly due to high predation pressure. We studied how habitat variables and predator communities in near-natural marshes affect the survival of turtle eggs and hatchlings. We followed the survival of artificial turtle nests placed in marshes along Lake Balaton (Hungary) in May and June as well as hatchlings (dummies) exposed in September.

The aim of this experiment was to investigate the effects of rumen fluid and molasses on the nutrient composition, fermentation quality, and microflora of Caragana korshinskii Kom. The trial included four treatments: a control group (CK) without additives and experimental groups supplemented with 7% rumen fluid (R), 4% molasses (M), and 7% rumen fluid + 4% molasses (RM). 15 days and 60 days of ensiling.

While numerous studies have established correlations between parasite load and negative effects on their hosts, establishing causality is more challenging because parasites can directly compromise host condition and survival or simply opportunistically thrive on an already weakened host. Here, we evaluated whether Ixodes uriae, a widespread seabird tick, can cause a decrease in growth parameters (body mass, bill length and growth rates) and survival of chicks of a colonially seabird, the black-browed albatross (Thalassarche melanophris) breeding on New Island (West Falkland). To investigate this, we daily removed the ticks from 28 randomly selected chicks during their first 14 days of life (treated chicks) and compared their growth and survival with 49 chicks of a control group.

This paper presented the preparation, characterization, and adsorption properties of Brazil nut shell activated carbon for catechol removal from aqueous solutions. The equilibrium adsorption of catechol molecules on this activated was experimentally quantified at pH 6 and temperatures ranging from 25 to 55 °C, and at 25 °C and pH ranging from 6 to 10. These results were utilized to elucidate the role of surface functionalities through statistical physics calculations.

Accurate prediction of runoff is of great significance for rational planning and management of regional water resources. However, runoff presents non-stationary characteristics that make it impossible for a single model to fully capture its intrinsic characteristics. Enhancing its precision poses a significant challenge within the area of water resources management research.
