In this article, we study the degree of dependence of heart rate variability in healthy adolescents and young adults on the average rhythm frequency. In the study group, heart rate variability decreased as heart rate grew. Although there was no difference in the increase in the heart rate, the variability of the ...

Frequency and variability of heart rate served as instruments to assess the stress resistance of two groups of students with different average academic performance in different periods of the educational process: at the beginning and at the end of the autumn semester. Mental stress always ...

A medical examination on a selected group of young people demonstrated a negative correlation between the body mass index and the heart rate at rest, which disappeared after some physical activity. Physical activity was observed to change the heart rate variability under the influence of the changes mag­nitude in the initial heart rate. No correlation between body mass index and heart ...

The Kaliningrad region has a sub-replacement fertility rate (with a total fertility rate of about 1.8) and a slightly negative rate of natural increase. With a net migration of up to 10,000 people per year (Russian regions account for 37 % of this figure), the population of the region is increasing and the ...

This article focuses on the major problems of studying one of the key aspects of the demographic history of the Kaliningrad region – the evolution of mortality rate in urban and rural population. Based on an analysis of statistical data from archival documents, the author considers the dynamics and characteristics of mortality rate. The key mortality rate indicators and the factors behind its decrease in the ...

The article is discussed about the structure analysis of the birth rate of the population of Kaliningrad region in 1949—1950th against All-Russian (RSFSR) and some regional indicators, drawn the conclusion about considerable originality of the structure of the birth rate as well as about greater significance of the ...

... 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 ...

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, ...

... water-plant -Galium palustre L.; grass — Solidago Canadensis; cereal — Secale cereal L. Collection and processing of the material was made in the area of Berlin/Brandenburg, Germany. Clark sensor-based method made it possible to determine the amount and rate of the oxygen evolution by plants in the dark and light phase. Under the reaction norm the average amount of the oxygen evolved and the average rate of metabolism processes during dark and light phases are changing simultaneously. Parabolic and periodic ...

... babies and disability in children and the need to accompany premature babies by a pediatric neuropsychologist in the Kaliningrad region. The disabled children in the Kaliningrad were registered from 2016 to 2020 through statistical reports of the birth rate of premature babies. Against the background of a decrease in the overall birth rate, there is no trend towards a decrease in the birth of premature babies, the disability of the child population has stable indicators. As a result, the most urgent ...

... breeding in urban conditions. Seven years’ (1999—2003, 2006 -2007) field studies resulted in the compilation of an atlas of the Kaliningrad region’s nesting birds. The city territory was divided into 206 plots of an area of 1 km2. The urbanisation rate was estimated on a scale of 1 to 5. Kaliningrad is home to 208 breeding pairs of coots and 56 of moorhens. The Coot is more widespread (present in 25.2 % of the plots) than the Moorhen (13.6 %). The population density of the Coot reaches 10—15 ...
