... research also reveals characteristic fea­tures of long-term dynamics of hydrological conditions in the south-eastern part of the Baltic Sea for 2005—2019. The average annual atmospheric pres­sure is close to regular and equals to 1014.6 ± 1.7 hPa; its growth is estimated at a rate of 0.10 hPa/year. South-west and west winds prevail and they in­crease their speed during cold season. Increase in the number of storms is shown (+ 2 storms/15 years), however, the duration of storms has decreased and the maximum recorded wind speed ...

... temperatures was evaluated by germinating seeds on filter paper at 10, 12, and 25 °C (control), as well as in soil at a constant 25 °C and under a regime of 10 °C for 10 days followed by 25 °C. Root system adaptability to low temperatures was determined by growth rate under a 25 °C → 14 °C regime and by the ratio of growth rates at low versus optimal temperatures. Correlations between traits were analyzed using SPSS and Excel. The study revealed significant differences among Vigna samples in cold tolerance ...

... grain (except rye) and industrial crops (except fiber flax) is the group of southern regions, and the commercial production of winter rye, oats, fiber flax is the agrarian regions of the central zone. For the southern regions, there is a trend of high growth rates of corn for grain, sugar beet, sunflower. The group of central regions is the main producer of livestock goods. Given the trends, the role of the southern regions in the production of beef cattle and poultry products will increase in the future....

... residents. The study con­cludes that, despite the extensive legal framework, the effectiveness of implemented measures in Saint Petersburg cannot be unambiguously assessed. First, negative trends are identified—such as declining marriage and birth rates, an increase in serious crimes among minors, and a rise in divorces—coexisting with positive developments, including the growth of large fami­lies, the maintenance of high educational achievements among schoolchildren, and the high status of children and the family in public opinion. Second, the article proposes new practice-oriented mechanisms to strengthen the family ...

... conditions. This study explores a novel freshwater microalgae isolate, Chlorella sp. B1, as a potential platform for biomass production. The research evaluated the isolate’s ability to grow in mixotrophic media. The results reveal a relationship between growth rate and dynamic changes in biomass composition. The use of granulated forms of the fertilizer “Fertika Universal” as a nutrient medium significantly increased the optical density of the initial solution to 0.087, more than doubling the results compared ...

This article presents the results of a study into changes in prices for goods constituting the minimum consumer basket. The analysis uses the indicative method based on studying variations in the chain growth rate of prices, trends method, and time series variation. The calculations made it possible to describe changes in prices for staple food in the Kaliningrad region over the past ten years. 1. Борисова А. А., Ермолаев М. Б. Проявление ...

.... Statistical processing relied on the SPSS, Statistica 8.0 software package, as well as the Microsoft Excel analysis package. Most often, women from among the indigenous small-numbered peoples of the north living in the city were underweight, while growth rates approached the newcomer population. The circumference of the hips and abdomen was statistically significantly higher among the small peoples of the North migrating to the city in comparison with those living in the village, as well as complications ...

... Western Borderlands. To attain the goal, first, the types of regions under study were identified (according to the selected typological features re­flecting the main natural and socio-economic characteristics of the regions) then GRP level, structure and growth rates were considered. The analysis re­sulted in the overall assessment of the socio-economic situation in regions of different types. Considering the typological features of the regions, the pro­spects for their future development based on the strengthening ...

This article examines the effect of prednisolone – an analogue of the ver-tebrate hormone hydrocortisone – on the activity of somatic growth, blood sys-tem function, fecundity, and reproductive rate in Daphnia Straus (1826) (Cladocera, Crustacea) in three consecutive generations. This hormone had a proven effect on the studied morpho-functional characteristics of Daphnia. It indicates that the test object is sensitive to exogenous hormones, ...
