The Relationship between Heart Rhythm Variability and the Heart Rate in Adolescents and Young Adults
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 ...
Young ‘s body mass index and its im¬pact on the frequency and variability of the heart rhythm at quiet and after phy¬sical load
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 Effect of Migration on Latvia’s Sex and Age Composition
The theory of Demographic Transition stipulates that the number of countries with the replacement and sub-replacement level of the total fertility rate is growing. In these conditions, population dynamics and the sex and age composition are increasingly affected by migration. The above holds true for Eastern European countries. Population decline has haunted Latvia for two and a half decades. Since ...

The LAC can occur during implantation and thus influence the observed yield of NV- centers of a certain type. We assume that during cascade transitions between the states of some NV- centers obtained by implantation,...
