Assessment of the diversity of vascular plants in phytocenoses with a share of Quercus mongolica on the territory of Relic Oaks State Reserve

In this paper, we assess the diversity of vascular plants in phytocenoses with Quercus mongolica (family Fagaceae) on the territory of the Relic Oaks State Reserve (Eastern Siberia, Transbaikal region), where Q. mongolica is located at the northwestern boundary of the areal. The descriptions of phytocenoses have been processed in the PAST3 application. The similarity of species composition has been determined using the Jaccard index. The resulting tree diagram shows two groups of descriptions at a similarity level of 0.14-0.15. The first group includes the descriptions of mixed forest quadrats, in which Q. mongolica is a co-edificator. The second group of descriptions presents the communities where Q. mongolica is the only species in the tree layer. The analysis of the tree diagram shows the dependence of species richness within the phytocenoses on the surface patterns and edaphoclimatic conditions. The phytocenoses located on steep southern slopes show less diversity

Seed morphology of some species in the family Gentianaceae

In this work, we investigated the outer and inner morphological characters of the seeds of 13 species in the family Gentianaceae. We also identified the main morphometric parameters and described the shape, coloration and sculpture of the seed surface. Some aspects of their internal structure were analyzed as well

Regional Aspects of Nosocomial Infection As a Medical and Social Problem

Prevention of nosocomial infection (NI) is an important medical and socioeconomic problem. And though certain organizational and practical measures are implemented in Russia every year to reduce NIs, the problem is still relevant from medical and social points of view. The risk of infection are both for patients and medical workers. In Russia, the minimum economic damage caused by NIs is 2.5–5 billion rubles annually. According to the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Republic of Mordovia, the total incidence of NI in the region is at a low level. The incidence rate was 0.01 per 1000 patients in hospitals. The dynamics of the last five years demonstrates a decrease in hospital-acquired infections. In the dynamics of the last five years, incidence rates of purulent-septic infections of newborns and postpartum women, postoperative purulent-septic complications and post-injection complications had an unstable downward trend. Thus, purulent-septic infections of newborns and postpartum women and postoperative infections are dominated in the structure of nosocomial infections. Analysis of dynamics of morbidity in recent years in the Republic of Mordovia suggests that the measures taken to prevent NI are quite effective and are manifested with consistently low rates

Complex correlation of two language systems: modern literary German of Germany and Austrian variant of German

The article presents a research of Austrian variant of German lexical variety. German language of Germany is a pluricentric language. It exists in some variants: standard variant of modern literary German of Germany and two variants of German in Austria and Switzerland. The relations between the standard form of the language in Germany and its variant in Austria are the main issue of the researc

‘World Will Never Be Same’: Phraseologisms during Coronavirus Pandemic

Issues related to the semantics, structure and functions of new super-word linguistic units that have come into active use during the coronavirus pandemic are considered. Particular attention is paid to the statistics of searching the Internet for a certain phrase for a month and specific digital indicators of its existence as a stable one. The novelty of the research is seen in the fact that identifies phraseologisms of the late XX — early XXI centuries, which need a full-fledged phraseographic description (origin, semantics, examples of use). Phrasemes are combined by the authors into thematic groups: 1) remote work and study, 2) administrative measures to combat coronavirus, 3) features of a new disease and its treatment. It is shown that in the texts of mass communication Phrasemes perform nominative, communicative and pragmatic functions. Investigating stable turnovers, the authors dwell upon their structure, which is represented by three models. It is noted that the result of the work will be a dictionary of phraseological neologisms, which, along with others, will include units that appeared during the coronavirus pandemic

Genetic factors in the development of pulmonary embolism

The article presents a literature review on the study of the relationship of FGA, FGB, F2, F5, PAI, ITGA2 gene polymorphisms with the development of pulmonary embolism (PE). We concluded that genetic factors in the development of PE are to a greater extent mutations in the F2, F5, PAI, ITGA2 genes. There is a positive correlation between the presence of combined genetic mutations and the development of PE. The study of allelic polymorphism of hemostasis genes makes it possible to predict coagulation system disorders, including PE
