Current state of knowledge of the liverwort and hornwort flora of the Vologda Region, Russia

An annotated checklist of liverworts and hornworts is presented for the Volodga Region, Russia, based on the authors’ collections and those of their colleagues, as well as the literature. The paper presents the first published checklist for the region and includes 84 species from 42 genera and 22 families. Three species are reported for the first time for the region: Conocephalum salebrosum Szweykowski et al., Scapania subalpina (Nees ex Lindenb.) Dumort., and Trichocolea tomentella (Ehrh.) Dumort.

Temperature-dependent magnetospectroscopy of HgTe quantum wells

We report on magnetospectroscopy of HgTe quantum wells in magnetic fields up to 45 T in temperature range from 4.2 K up to 185 K. We observe intra- and inter-band transitions from zero-mode Landau levels, which split from the bottom conduction and upper valence subbands, and merge under the applied magnetic field. To describe experimental results, realistic temperature-dependent calculations of Landau levels have been performed. We show that although our samples are topological insulators at low temperatures only, the signature of such phase persists in optical transitions at high temperatures and high magnetic fields. Our results demonstrate that temperature-dependent magnetospectroscopy is a powerful tool to discriminate trivial and topological insulator phases in HgTe quantum wells

VARIABILITY OF GENES OF FOLATE CYCLE IN CHILDREN WITH ESSENTIAL ARTERIAL HYPERTENSION

We realized, the definition, of polymorphic variants of genes of folate cycle (C677T, A1298C, A66G) in children with, essential hypertension, having the burdened, and not burdened, hereditary anamnesis of thrombosis. Frequency of the incidence of low functional allele polymorphisms C677T and. A1298C didn't exceed, ubiquitous in the general population, and. in agreement with, those obtained, in other studies, with, an unfavorable genotype GG A66G gene was more frequent than in the population. In all groups of children studied, most often occurred in the carriage of any one of the polymorphic genes, but the combination, of two or even three adverse alleles also met with, relatively high, frequency. No statistically significant differences in the distribution, of genotypes between groups were found

Private Health Insurance in the Post-Pandemic Era: Spatial Econometric Market Development Analysis

The post-COVID era has posed unprecedented challenges to healthcare systems worldwide, urging a reevaluation of healthcare financing mechanisms. This study investigates the evolving landscape of private health insurance markets in the aftermath of the pandemic while considering the influence of international sanctions. Employing a spatial lag model (SLM), data from Albania, Russia, and Malaysia were analyzed to uncover the intricate interplay of factors shaping private health insurance coverage rates. The findings reveal nuanced patterns and disparities across these countries. The significance of variables varies: while private insurance share and government health expenditure consistently exhibit positive and substantial impacts on coverage rates, the unemployment rate presents differential effects. COVID-19 deaths influence coverage in Russia, emphasizing the pandemic's specific impact. Moreover, hospital beds’ significance in Malaysia underscores healthcare infrastructure's varying importance. Importantly, the spatial lag effect is consistently significant, emphasizing regional interdependence. Collectively, our study highlights the multifaceted determinants of private health insurance coverage, revealing insights crucial for policymakers navigating post-pandemic healthcare financing challenges among international sanctions. Doi: 10.28991/ESJ-2023-07-06-013 Full Text: PD
