Despite the rapid urbanization of landscapes and the active development of cities, situations of conflict coexistence of people and birds in cities are increasingly emerging. We analyzed the problem of increasing the number of corvids in cities, based on our own research and data for previous years.

This article presents the processed data of PM2.5 and PM10 particulate matter of the AirMQ sensor on Zakharova street, Minsk. The 15 minute readings were averaged to the daily average, monthly average and annual average values for the period August 2019 - January 2021. The analysis of data by seasons of the year, by 15-minute periods of observations and by days of the week is presented. Conclusions are made about the possible natural and anthropogenic causes of daily, weekly and seasonal changes in the content of PM2.5 and PM10 solid particles in the surface air at Zakharova Street in Minsk. An analysis is made of the relationship between solid particles and the urban heat island (surface air temperature) in the area of Victory square.

To test the effectiveness of the dose delivery system of the treatment plan in intensity modulated radiation therapy, quality assurance systems are used. The main tool for verifying the correspondence between the reference and the estimated dose distribution is Y—indexing. In the process of Y—analysis of individual dose distributions, both point dose values and geometrical offset between the reference and delivered distributions are evaluated. To check the compliance of dose distributions, the concepts of action limits and tolerances are used. The action limits are defined as the total percentage of the estimated value by which deviation of the indicators checked by the quality assurance system is allowed, with a minimal risk of harm to the patient. Tolerances are defined as the boundaries of the magnitude change within which the treatment process is considered to be performed according to the prescribed conditions.

Environnemental features of corvus frugilegus in urbanized landscapes of the capital and regional centres of Belarus are considered. The dynamics of the population of the species depending on the differentiation of housing development and anthropogenic load is determined. The nature of the biotopic, spatial distribution of rook colonies and estimated indicators of the number of species in the city of Minsk were revealed.

The complement system refers to important homeostatic active systems that are under stress from environmental factors. Taking into account the significance and role of the complement system in the effector reactions of immunity and the relationship of complement with various homeostatic systems of the body, it is important to understand how complement changes in various pathological conditions of the body. To do this, we need to have a clear understanding of the state of the complement system in a clinically healthy body.

The article presents the results of the survey of the soil cover of the estuarine territories of boreholes at the «Sary-Uzen» site. The site is located on the territory of the Semipalatinsk Test Site (STS) and an underground nuclear test was conducted in the boreholes. In the study area, a survey was conducted using pedestrian gamma-ray spectrometric surveys and assessment of levels of radioactive contamination of the soil. A total of 2 main groups were identified. The first group includes boreholes, on the mouth area of which there is radioactive contamination of the soil (19 boreholes). The second group includes wells in which there is no radioactive contamination of the surface soil layer (9 boreholes). According to the results of the survey, the specific activity values of 137Cs,241Am, 90Sr, 239+240Pu were determined.

The comparative study of the antioxidant activity of extracts of native, defatted, and fermented colostrum, as well as ultrafiltrate defatted colostrum, hydrolyzed native, and defatted colostrum and fermented defatted colostrum. The dependences of the fluorescence intensity of fluorescein on the logarithm of the concentration of all colostrum samples are obtained, from which IC50 values are graphically determined. Colostrum samples restored fluorescence of fluorescein to 66-93 % at a sample concentration of 0.23-1.0 mg/ml. IC50 values were in the range of 6.2155.1 gg/ml.
