The seasonality expressed in motility of frog Rana Ridibunda Pall 1771 erythrocytes and leukocytes in agarose gel under the influence of the temperature

The agarose migration test rexealed the influence of temperature on seasonal fluctuation of locomotional activity of nuclear hemocytes of frogs of the genus Rana Ridibunda Pall. It’s been shown that at different incubation temperatures, the spontaneous migration area of blood cells changed in spring and summer, and did not change during autumn and winte

Effect of temperature on the morphometrical and physical parameters of erythrocytes and polymorphonuclear leucocytes in Carassius gibelio (Bloch)

Dynamics of the morphometric and physical properties of hemocytes of the Prussian carp Carassius gibelio (Bloch) under the influence of a temperature factor has been studied with atomic force microscopy in experiments in vitr

Seasonal fluctuations of migratory activity of ertebrate nuclear hemocytes at different incubation temperatures

Agarose migration test has shown that nuclear erythrocytes of Cyprinus carpio, Rana ridibunda, and Gallus domesticus are capable for spontaneous locomotions. The migration of red blood cells from frogs is associated with formations of long pseudopodia, whereas that from carps and hens - with short protrusion

Functional capabilities of cardiovascular system of adolescents

We have studied functional capabilities of cardiovascular system in young men of service age in terms of indicators of сardiointervalography. It was stated that people who are 18-21 years old demonstrate increase of values of systolic, diastolic pressure and heart rate after physical activity in comparison with the values obtained in the rest state, while range values of Р, Q, R, S and Т deflections, interval sizes of P-Q, QRS and Q-T, reference and actual reference systole and systolic indicator decrease. Vagosympathetic index of the test persons after the functional test increased as compared with the rest state, which provides evidence of increase in tonus of sympathetic nervous system after physical activit

Improving educational process quality in the lessons of natural and mathematical cycle by means of stem-training

Today, the educational process is focused on the development of personal characteristics that meet the requirements of a modern educated person. In this regard, the task of educational institutions is to adopt the educational process to today’s realities. To achieve this goal, STEM education is implemente

Leukocytes phagocytic activity under moderate hypotension conditions in some representatives of bony fish, amphibians and reptiles

The leukocytes phagocytic activity against Bacillus subtilis and agromerulated latex particles in representatives of bony fish, amphibians and reptiles under reduced medium osmolarity conditions was studied. It was found that in moderate hypotension compared with isotonia, the white blood cells absorption capacity of the fish was not changed, but it was reduced for amphibians and reptile

Digitalization in STEM education: experience of empirical research

The purpose of the study is to identify the interest of schoolchildren in STEM disciplines, to study the factors and features of their teaching in general education organizations in Russia and the Republic of Kazakhstan, to identify ways to solve the problem of STEM education digitalization for further development of senior schoolchildren motivation to professional self-determination and education in the scientific and technical field of activit

Physical modeling of various processes in development of the system for monitoring the concentration of suspended particles in the air

The paper shows the need to develop a system for monitoring the concentration of suspended particles in the atmosphere, ensuring industrial safety at enterprises, facilities and in rooms with high dust content. The main possible consumers of this system are presented. Different measuring techniques of suspended particles and their fractions in the air are described, their advantages and weaknesses are mentione
