FEATURES OF COMMUNICATION IN THE ELECTRONIC INFORMATION AND EDUCATIONAL ENVIRONMENT IN THE CONDITIONS OF DISTANCE LEARNING ^{[№ 2 ' 2022]}
The field of higher education can be called one of those that the COVID-19 pandemic has had the most impact on a global scale. The changes affected, first of all, the format of communication. The aim of the study was to study the preferences of students in the use of social networks, instant messengers for communication, platforms for posting content, video conferencing services for online lectures and consultations during the periods of May-June and November-December 2020. The study showed that in the period May-June 2020, respondents preferred WhatsApp in 50% of cases, email 42.8%, video conferencing services Zoom Meetings 3.6%, Google Meet web application 3.6%. That testified to the role of mobile means of communication in the educational process. The second survey, which took place in November-December 2020, showed a trend of using Zoom Meetings at 50%, email at 28.6%, WhatsApp at 7.2% of cases. According to the respondents, Zoom Meetings proved to be the most convenient tool (72.4%), which, according to users, has a functional interface (75.8%), the ability to share a screen (89.6%), an audio recording and video recording service of a conference ( 96.5%. In turn, Skype was considered convenient for video conferencing by only 13.8% of respondents, along with this, a big minus was noted — there was no possibility of screen sharing. Thus, it is difficult to overestimate the impact of the pandemic on the transition of higher educational institutions to a remote form of work, which radically changed communication in the electronic information and educational environment of universities and posed the problem for the teaching staff in an extremely short time to master digital tools for implementing the educational process using distance learning technologies.

PSYCHOPHYSIOLOGICAL AND METABOLIC ASPECTSOF ADAPTATIONAND DISADAPTATIONOF STUDENTS ^{[№ 13 ' 2015]}
Stress factors are the causes of emotional stress, reduced functional reserves of the organism, stress leads to increased morbidity and mortality. That's why studying of the mechanisms of adaptation and disadaptation of person has special importance. The article presents the results of long-term studies of the psycho-physiological and metabolic parameters'changes during the adaptation to various environmental conditions. The peculiarities of physical development, lifestyle, eating habits, bad habits, as well as cardio and metabolic parameters in students of different ethnic groups were investigated. Elemental portrait of young men with information about the features of the element status shows that most abnormalities are not related with ethnicity, but are related with the region of residence. At the same time, it was shown the influence of the person individual characteristics on the process of adaptation of students. Correlation analysis between psychological indices and the parameters of adaptation showed that the largest number of correlations between psychological characteristics and cardioindicators were in the group of Tatars. In addition, it is was shown that the functional hemispheric asymmetry of the brain affected on the body's ability to adaptation. Right hemisphere dominant young men hada higher rate of reaction according to the tests "assess attention", "noise immunity", "simple hand-eye reaction". Regardless of the type of functional hemispheric asymmetry, the young men had deficient of cobalt, selenium, an excess of lithium, iron and zinc, compared with the optimal interval centile. Thus, the adaptability of the organism depends on many factors, and defining factors are ethnic characteristics, the type of functional hemispheric asymmetry, lifestyle and environmental living conditions.

CHARACTERISTIC SPECIFIC FEATURES TO BIND CADMIUM TREES CITY OF ORENBURG ^{[№ 10 ' 2015]}
In this article the problem of specific feature of bodies of wood plants (leaves and bark) of the city of Orenburg is considered to accumulate cadmium. The main way of intake of cadmium to trees of the city of Orenburg is not the root, but foliarny way, and the main source of cadmium for trees of the city of Orenburg is an atmospheric precipitation. The total coefficient of biogeochemical activity showed that kadmiysvyazyvayushchy ability is higher at wood plants from the area with low cadmic loading that testifies to inclusion by trees from areas with high loading cadmium of the physiological barrier mechanism. The content of cadmium in leaves and bark depends on a species of wood plants and level of anthropogenous pollution and exceeds maximum concentration limit at a birch warty (Betula pendula L.) and poplar black (Populus nigra L.) from the area with authentically high level of pollution by cadmium of the soil and a snow cover. The content of cadmium in leaves and bark of other studied species of wood plants meets standard. The vidospetsifichnost of ability of wood plants to cadmium accumulation which is reliable above at a birch warty (Betula pendula L. is revealed.). A specific number of trees on ability of leaves to connect cadmium following: birch warty (Betula pendula L.)> poplar black (Populus nigra L.)> elm fine-leaved (Ulmus pumula L.)> ash-tree ordinary (Fraxinus excelsior L.). For gardening of an urban environment of Orenburg it is expedient to use a birch warty (Betula pendula L.) as a look capable to high accumulation of cadmium in elevated bodies, and capable to absorption of cadmium not only from the soil, but also from atmospheric air.

THE TOTAL CONTENT OF LEAD AND ITS MOBILE FORMS IN GROUND REGIONS ORENBURG REGION ^{[№ 10 ' 2015]}
One of the important problems of modern ecology is the accumulation of heavy metals (HM) in ground in the plant communities of which is reflected in all components of the biosphere. Analyzed the accumulation of heavy metals — lead in different plant ground steppe zone Orenburg region. Soil science has significant dates about the patterns of behavior of trance elements in soils. The content and distribution of trace elements depends on many chemical, physical and physical-chemical properties of the soil, the main of whish are state grain size, content and quality of humus, the reaction medium. However to find quantitative relationships between different indicators of soil properties, and the content of trace elements is very difficult, because the soil is a complex heterogeneous system. Studying the influence of the properties of soils and rocks on the content of trace elements in the topsoil have been devoted to domestic and foreign scientists. Many studies have shown that the accumulation of trace elements in soils primary rove belongs to the soil-forming rocks. The material resulting from the destruction and weathering of parent rock, naturally reflect their composition in relation of micronutrients. Soil, geochemical usually, inherit the trains of their parent rocks, but on the content and distribution of trace elements in the soil-forming process is applied influence. Content as a gross and moving forms of trace elements in soils determined by their concentration in soil-forming rocks. Significant impact on the migration of trace elements in soil environment. Closely related relative activity of the cations and anions of a chemical reaction between the elements and thus the formation of there or other natural compounds characterized by different solubility and availability for plants. Heavy metals can accumulate in the lower soil horizons, regardless of their origin. The total content of mobile forms in less characteristics of sandy soils in much greater-for loamy. That is, there is a close relationship between the content of mobile forms of elements and the composition of soil texture.
