Stress Factors of the Virtual Environment of a Metropolis: Perception of Youth

The purpose of this article is to study typical stress factors of the urban environment in its virtual refraction in the context of the subjective assessment of their importance by urban youth. As a result of a survey of 210 respondents, in the age range from 18 to 30, living in two large cities of the Ural Federal District, Ekaterinburg and Tyumen, a list of typical stress factors of a virtual city environment was identified, among which the most mentioned by young people are an overabundance of information and a violation of the usability of the information content, and the most stressful are the intrusiveness of virtual city services and deanonymization.The study was carried out with the financial support of the Russian Foundation for Basic Research, Project No. 20-013-00830 Real and Virtual Space of a Metropolis: Stress and Behavioural Deviations of Urban Youth”

Universal and national cultural features of the naming in sports

The features of the sports language picture of the world in the context of the French culture of language, whose key element is the linguistic personality, who acts as the actor of the communicative process related to sports activities (both professional and amateur

Comparative analysis of habitus and behavioral responses in birds in desynchronosis conditions

The dynamics of behavioral reactions is studied. Habit, live weight of roosters in artificially created models of desynchronosis: acute, due to three-day inversion of the light regime, and chronic, due to crowding - increased placing density. An assessment of the behavior, habitus, feed intake, feather cover and molting conditions in combination with the glycemia level, which together provide an objective assessment of the effect of desynchronosis on the functional state of birds and their adaptation to acute and chronic stres

The aim of the work is to create new adapted varieties resistant to the complex of biotic and abiotic factors on the basis of the use of Phacelia tanacetifolia Benth. morphological and biological characteristic

Biofouling growth on plastic substrates: Experimental studies in the Black Sea

Despite long-term research on marine litter there is still insufficient knowledge about benthic organisms associated with these substrates, especially experimental studies and methodology of sampling for complex biofouling assemblages. To predict the fate of plastic in the marine environment it is necessary to know how long the macrolitter can stay in different sea matrices and what are the steps of colonisation by marine organisms. The experiments were carried out during various seasons in situ in the north-western Black Sea coastal area. Three new types of the experimental constructions intended for different durations of exposure (1–10 months) were designed. This article is the first to present the methodology and the results of complex experiments investigating marine fouling (from microalgae to meio- and macrofauna) on plastic surfaces. Overall, 28 genera of microalgae, 13 major groups of meiobenthos and 36 species of macrofauna were found on plastic during the experiments. The microalgae fouling was mainly formed by representatives of genus Cocconeis. The species composition of microalgae was common for the research area. The average density and biomass of meiobenthos were the greatest on I construction type after 8 months of exposure. In the total macrozoobenthos biomass and density of Bivalvia and Crustacea dominated, respectively. The obtained results on the interaction between fouling organisms and plastic materials in the marine environment form an important contribution to the understanding of the "good ecological status" of the sea. Additional studies based on the tested methodology could be used as a component of ecological monitoring during development and implementation of the approaches of the Marine Strategy (descriptor 10)

Biological resources of natural forage grassland of the cretaceous south of the European Russia

The main objective of the made researches was assessment of territorial confinedness of economic and valuable plant species and also a status and productivity of a natural forage grassland within agrolandscapes of the cretaceous South of the European Russia (the territory of the Belgorod region). Biological and vegetable resources of the natural forage grasslands of the East part of the Belgorod region in a subband of the southern forest-steppe were studie

Biological resources of the Fabaceae family in the Cretaceous south of Russia as a source of starting material for drought-resistance selection

The aim of this work is the study of biological resources of the genera Medicago and Trifolium species in Cretaceous South of the Central Russian Upland as the most valuable in genetic and economic term

Some ways of filling of the vascular bed of domestic animals

In this work the assessment of some methods of filling of the mammals blood channels is presented. As injection masses there were used the gelatine solution of 5%, painted with the ink by Borisevich V.B. technique and the solution consisting of Bustilat-M glue and the water in a proportion of 2:1. The conducted researches showed that the most successful, in terms of simplicity of execution, is filling of vessels with the solution consisting of Bustilat-M glue and water, as it allows with the little effort and with the smallest expenses to fill in both large and average vessel
