The atmospheric electric field Ez is the most urgent problem of study of the physics of the atmosphere and the processes occurring in it. The conducted studies show the relationship of the electric field with atmospheric processes. Monitoring its changes is necessary to solve practical problems. This article presents brief characteristics of the installation of the EFM-100 electrostatic fluxmeter of the scientific cosmophysical experimental complex at the L.N. Gumilyov Eurasian National University (ENU) and its experimental data obtained in 2020. The article presents the results of observation of atmospheric-electrical characteristics near the Earth's surface and monitoring of the electric field of the atmosphere of the city of Nur-Sultan, in particular, estimates of the variation of the electric field of the surface layer of the atmosphere during sunrise and sunset based on data obtained by the EFM-100 fluxmeter. The comparison of meteorological data with the data of the electric field strength of the atmosphere is given. The analysis of the days and months in September and October 2020, when the conditions of “good weather” were manifested, was carried out. The series of electric field data obtained at other measuring stations show the characteristic periodicity of the electric field behavior. It is established that the value of the atmospheric electric field increases during sunrise with the manifestation of the solar terminator effect. It is interesting to study the relationship between the magnitude of the electric field of the atmosphere and the intensity of the cosmic ray flux, especially in the case of Forbush effects. The data of the ENU ground-based experimental complex allows us to conduct research on the study of atmospheric physics, including atomic electricity, as well as their interaction with cosmic rays and meto-conditions.

Based on Zakharov's equations, Karpman et al. claimed that there were solitons in the magnetosphere. According to the model proposed by Goldreich and Julin, there is a strong induced electric field in the magnetosphere. It seems that we should include the nonlinear effects of the electric field on the polarization of hydrogen atoms if there really are some hydrogen atoms spreading in the magnetosphere of the pulsar. Assuming the magnetosphere is symetric, therefore the electric polarization of hydrogen atoms is of the form P=χ(1)E +χχE3. We treat χ(1) and χ(2) as scalars because most hydrogen atoms in the universe are in the ground state and χ(3) is much smaller than χ(1).

This study was made to investigate the relationship of surface meteorological data and corresponding surface refractive indices to radio field strengths in the FM frequency band. For meteorological observations during which the wind speeds were equal to or greater than 10 mph, and when fronts, low overcast clouds (less than 5000 ft), rain, thunderstorms and fogs were excluded, a 0.70 correlation coefficient was found between hourly surface refractive index and hourly median field strength over a Washington-Richmond path at a frequency of 96.3 Mc.

Electrorheological fluid (ERF) is a new kind of smart materials, which has a great deal of market value and broad application prospects. To meet the needs of the ERFs performance testing, design and produce of the ERF's performance test system are based on the relationship of the apparent viscosity, shear stress and electric field strength. Select the NDJ-8S digital viscometer, high voltage DC power supply, liquid container, and other parts to constitute the ERFs performance test system after considering the relationship of the apparent viscosity, shear stress, shear rate and electric field strength. The system has potentials to control voltage, change velocity, change the distance between the parallel panels, and test the yield stress of the ERF, shear stress, viscosity and other parameters. The study introduces the hardware and software device, the related experiments, and obtains the relationship of the viscosity, rotational speed, voltage, and plate gap.

The Relationship

Based on the analysis of geological data and meteorological data of landslide, the mechanism of rainfall-induced landslides was analyzed, and the relationship between landslide and rainfall was further discussed, including the landslides and rainfall distribution, the relationship between landslide and frequency of rainstorm, and the time relationship between landslide and rainfall. The results show that the probability of landslide occurrence and the quantity of landslides have positive correlation with rainfall. The landslides mainly occur from May to September in which the monthly mean rainfall is large. Meanwhile, landslide occurrence is closely related to the characteristics of rainfall of that day and rainfall of early days. When the daily rainfall exceeds 50mm or 10 days accumulative rainfall exceeds 100mm, the landslide is prone to occur and the occurrence rate of the latter is higher.

The main objective of the study is to find out about physical activity of students from Poland and Ukraine, and its determining factors, as well as the amount of their free time. The study was conducted in March 2020 with 100 students from two universities surveyed (50 persons from each). They were students of Tourism and Recreation at the Jan Długosz University of Humanities and Sciences in Częstochowa and 50 students with major in Tourism at the Lesya Ukrainka Eastern European National University in Lutsk. The students surveyed were both undergraduate and graduate. No relationship was found between the distribution of gender and nationality (p = 0.799). There is also no relationship between the distribution of the amount of free time and nationality: on school days (p=0.062) and at weekends (p=0.294). The relationship of the distribution of practising physical activity in free time and a nationality (p = 0.029) was found. What is significant is also the impact of nationality on the distribution of responses (p=0.013) as for the analysis of who accompanies students during physical activity in their free time. In turn, there is no relationship between the distribution of students' motivation to practise physical activity in free time and nationality (p=0.175). Physical activity in free time is practised by 92.00% of students from Poland and 76.00% of students from Ukraine. The leading role in the promotion of physical activity in free time among Polish (46.00%) and Ukrainian (64.00%) students is played by teachers. The most popular form of physical activity is walking (Poles 52.00%, Ukrainians 70.00%).
