Authors: Alekhin A.D. , Bilous O.I. , Rudnikov Ye.G. 
Published: November 2021

Based on the literature data of PVT measurements, the amplitudes of the equations of the critical isotherm D0(Zk), the critical isochore Г0(Zk), the phase boundaries В0(Zk) are expressed in terms of the critical factor of compressibility of the substance Zk=PkVk/RTk in the entire fluctuation region near the critical point. By doing so, a phenomenological method has been used for calculating the values of the critical exponents of the fluctuation theory of phase transitions based on the introduction of small parameters into the equations of the fluctuation theory.
It has been shown that, within the limits of the PVT measurement errors, these dependences D0(Zk) and В0(Zk) on the compressibility factor are linear, and Г0 practically does not depend on the compressibility factor Zk.
The relationship of these amplitudes with the amplitudes a and k of the linear model of the system of parametric scale equations of state of substance near the critical point has been established. It has been shown that the dependences k(Zk) and а(Zk) are also linear in the entire fluctuation region near the critical point. The obtained dependences k(Zk) and а(Zk) agree with the known relationship between the amplitudes of the critical isotherm D0(Zk), critical isochore Г0(Zk), phase boundaries В0(Zk) Aerospace Institute of the National Academy of Sciences of Ukrainewithin the framework of the system of parametric scaling equations.
The relations а(Zk), k(Zk) make it possible, on the basis of a linear model of the system of parametric scale equations of state of substance, to determine such important characteristics of the critical fluid as the temperature and field dependences of the correlation length Rc(T,m) and the fluctuation part of the thermodynamic potential Ф(T,m) in the entire fluctuation region near the critical point.
Then, based on the form of the fluctuation part of the thermodynamic potential Ф(T,m)~Rc(T,m)-3, the results obtained allow one to calculate the field and temperature dependences of the thermodynamic quantities for a wide class of molecular liquids in the close vicinity of the critical point (DP<10-3, Dr<10-2, t<10-4), where precision experiments are significantly complicated, and its can also be used when choosing the conditions for the most effective practical application of the unique properties of the critical fluid in the newest technologies.

Published: November 2021

The rheological properties of the gel-like material, the monomer of which is a crosslinked and modified 2-propenamide of acrylic acid, were determined by relaxation rheometry methods. The values of its elastic modulus and modulus of losses and complex viscosity depending on: deforming stress and its frequency are determined; relative deformation; temperature in the range (20-100) ° C and the regularities of these dependences are noted. It is established that: 1) the dependence of the modulus of elasticity (G'); modulus of loss (G'') and complex viscosity from: relative deformation; voltage; temperature; frequencies indicate that in the linear scale they change according to nonlinear dependencies, and in the transition to the logarithmic scale contain plateau-like areas; 2) analytical dependences of the above parameters on stress, strain rate and temperature are complex and difficult to establish; 3) in the range (20-80) ° C and relative deformations (10-100)% hydrogel has a virtually unchanged value of the modulus (G ') ten times greater than the modulus (G' '), whichdetermines the uniqueness of its rheological and biophysical properties ; 4) in the region (20-80) ° C hydrogel in terms of modulus of elasticity and tangent of the angle of loss is close to a completely elastic body; 5) when the frequency of the deforming voltage is more than 15.8 Hz and the relative deformation ≥100%, the gel is brittlely deformed; while the modulus of its elasticity decreases abruptly and the modulus of losses increases rapidly with increasing frequency of the deforming stress. 6) the dependence of the elastic-viscosity characteristics of the samples washed and unwashed in saline gel in the temperature range (20-80) ° C differ little and indicate that the equilibrium structure of the hydrogel 2-propenamide acrylic acid belongs to the typical colloidal dispersed structure of gelatinous substances.

An investigation of the saturated vapor pressure for the solutions of propane in the two type of industrial compressor oils ProEco®RF22S and RENISO SP46, also as in oil ProEco®RF22S containing fullerene C60 6.837·10-4kg·kg-1is presented in this paper. The measurement of the saturated vapor pressure was conducted using a static method in a temperature range (273…333) K and thepropanemass fraction (0.11…0.595) kg·kg-1.
An analysis revealed that the expanded uncertainties of the measured saturated vapor pressure do not exceed 0.0419·105Pafor solutionpropane/ProEco®RF22S,0.0716·105Pa for solution propane /RENISO SP46, and 0.0095·105Pa for solution propane/ProEco®RF22 Scontaining C60.The temperature and concentration dependences of the saturated vapor pressure for the object of study have been discussed. The excess of saturated vapor pressure for the solution of propane in oil ProEco®RF22S over the pressure of the solution of propane in oil RENISO SP46 reaches 1.5 105 Pa at a temperature of 330 K and propane fractionof 0.1 kg·kg-1. This effect decreases with temperature decreasing and propane fraction increasing.It was proven that the additive of the fullerene C60 increase the saturated vapor pressure of the solution propane/ProEco® RF22S up to 0.4·105Pa at low temperature and low propane mass fraction insolution.
The results obtained proved the expediency of the introduction in the industry the solution of propane/compressor oil ProEco® RF22Scontaining the fullerene C60 as working fluid of vapor compression refrigeration system. The ability of C60additive in oil to increase the saturated vapor pressure of considered working fluid will contribute to increasing the energy efficiency of refrigeration systems.

Published: November 2021

In this work we studied the emission spectra of the combustion products of low-volume dust clouds (V = 5 L) from aluminum (ASD-4), as well as clouds from mixed compositions of aluminum with inorganic powdery oxidizing agents (NaNO3, NaCl, Na2CO3·10H2O, Sr(NO3)2, Ba(NO3)2, KNO3, CuSO4, CuSO4·10H2O) and combustible (B, AlB2, Cu). This article discusses the possibilities of purposeful modification of the emission spectrum of the base composition using various inert and optically active dispersed additives that shift the maximum of the emission spectrum of the fuel composition to the region of longer waves or cause a local change in the emission spectrum in the corresponding spectral regions.
In the course of the experiments, it was revealed that the introduction of additives into the basic composition of dispersed fuel does not significantly change the dynamic characteristics of the suspension. However, the additives lead to a decrease in temperature (by about 100–200°K in the presence of an additive up to 25% by weight) and to a corresponding shift in the maximum of the radiation spectrum.
The possibility of a significant local modification of the spectrum in the yellow region with the help of inorganic additives to the fuel of sodium salts with a low decomposition temperature (additives Na2CO3·10H2O) was shown experimentally. Boron additives and boron compounds (B, AlB2) leads to a significant increase in the luminosity of the flame in the green region of the spectrum with a maximum radiation in the range Δλ = 530 ÷ 580 nm. The article presents the lighting characteristics (luminous intensity, light sum) of large clouds (V ≥ 10 m3) of mixed compositions based on PAP-2 aluminum powder.
It was found that the introduction of inorganic additives to the base fuel does not lead to a noticeable change in the lighting characteristics, but somewhat increases the time of the cloud glow both in the visible and infrared parts of the spectrum.

Published: November 2021

Problem statement. It is shown that the main scientific vectors of the study of the personality image of the future can be considered philosophical, sociological, psychophysiological and psychological. In psychology, the future is revealed as a property of the mental. It is determined that the psychological phenomenology of the image of the future is that it is a holistic view of the individual about the future. It is in the mind and constantly affects behavior, activities, and its emotional state. The ability of an individual to construct his own future is due to the peculiarities of his individual psychological representations. This aspect is little studied in psychological science. The purpose of the article is to present methods and techniques of research of representations and designing the world image of the future by the person. Results of the research. It is noted that the process of forming the image of the future is not only a vision of the end result, but also the impact on the assessment of behavior, consolidation of moral, volitional, intellectual efforts to realize their own expectations. This emphasizes the subjective nature of this process. In the framework of the research of mental representations and the peculiarities of constructing personality images of the future in a particular individual context were identified the mediative and moderative components that influence this phenomenon. The author’s method of assessing the world image of the future is presented. It is a technique of subjective scaling — that is, it shows how the individual imagines his future. To assess the relationship between the studied indicators, which are operationalized as concepts of psychosemantic analysis, a multidimensional deployment was used. Conclusions and prospects for further research. It is concluded that the psychosemantic approach is the most informative in the identified abilities of the individual to construct images of their own future. It is noted that the prospects for further research will be to identify the re lationship between forms and strategies for building mental representations of the image of the future with strategies for individual behavior in difficult life situations.

Published: November 2021

Abstract
Agricultural practices are generally organic and inorganic practices. Organic agriculture is more about producing agricultural products without disturbing the ecosystem, biodiversity and the soil health; whereas, inorganic farming is completely opposite of organic farming. Use of chemicals nutrients, hybridisation of seeds, chemical fertilizers, pesticides, is commonly used to get high yield. Since inorganic agriculture is practicing from long time and we are used to get more yield in less time, farmers are bit hesitant to change to organic farming. Behavioural, economic and social attributes of the farmers largely influence the future of organic farming. Objectives: The principal aim of the study is to assess the attitude, perception, lifestyle and satisfaction of organic and inorganic farmers. Methodology: A sample of 30 organic and inorganic farmers were selected from different districts of Karnataka state. Semi-structured tool was designed to collect data from the farmers through interview method. Thematic and free-listing techniques were used to analyse and present the data. Results: Organic farmers tend to be resilient and motivated as compared to the inorganic farmers. There were issues as perceived by the inorganic farmers that the organic farming was not an easy way to reap economic benefits and high yield for which conventional farming has been in practice. However, the shared views were that the agriculture has to receive the due place and dignity as compared to other market occupations which are more profitable. Conclusion: The study observes that organic farming needs sustainable systems to support, promote, advocate and practice it. Behavioural domains and economic domains are equally important to influence the lifestyle and satisfaction of the farmers.

Published: November 2021

The methodology of creating multifunctional acoustic automated devices has been further developed, it is based on the construction of simple algorithms for transforming and processing signals of measuring instruments. A differential acoustic method for controlling the physical and mechanical parameters of multilayer plates made of slag glass-ceramics has been investigated. A structural diagram of an automated device for measuring acoustic control of the ultimate compressive strength Rр of a controlled slag glass-ceramics plate is proposed. The option of automation of the measurement process considered in the article makes it possible to carry out measuring control of the strength characteristics for a relatively short period of time and by averaging the results of measurements of the physical and mechanical parameters of slag glass-ceramic plates, leads to a decrease in the values of random measurement errors and thereby contributes to an increase in the accuracy of measurements of physical and mechanical parameters of slag glass-ceramics products. The values of the relative increments of the attenuation coefficient ∆ƞ23/ƞ4were obtained, while the ranges of the values of the attenuation coefficient of a transmission of various waveforms of the piezoelectric transducer correspond to the ranges of the compressive strength Rр of the test sample. At the same time, the control of the strength of the material Rр at multiple frequencies is due to the fact that even a slight change in the geometric parameters of the slag glass-ceramics slab leads to a change in the generalized parameters of the universal transformation functions of the measuring differential acoustic devices, which are associated with the physical and mechanical characteristics of the controlled material of the sample The proposed two-parameter differential acoustic control method allows to keep in mind the linkage between temperature and mechanical parameters: the unequal distribution of the temperature along the length of the sample and the uneven distribution deformation of temperature with the localization of this plastic component in the middle part of the slag glass-ceramics plate, which is most significantly affected by temperature and, as a consequence, is subject to gradual destruction.

Based on the literature review found that the natural symbionts Medusomyces gisevii and Oryzamyces indici biotechnology are a valuable objects. It is urgent to find ways to impact on it in order to obtain these or other products of its life activity.
At present, it is urgent to search for microorganisms producing enzymes, including amylase. One of the most promising in terms of biological objects is a natural microbial symbiont Medusomyces Gisevii (tea fungus) and Oryzamyces Indici, which, thanks to the not identical, microbiological composition and different growing conditions may have a different composition of metabolites. Studies of the amylolytic activity of the culture liquid Medusomyces Gisevii and Oryzamyces indici with different cultivation periods have been carried out. Cultivation of the fungus was carried out in the laboratory according to the classic method. The optimal concentration of sucrose for Medusomyces Gisevii and Oryzamyces Indici biomass growth was set at 5%. Sucrose concentration of 15% and above is not recommended for use due to inhibition of biomass growth with increasing concentration of carbohydrates in the culture medium. It is established that these symbionts start to show the amylolytic activity already on the 10th day of cultivation cultivation in standard nutrient medium, medium supplemented with 10 % milk and serum-based medium and stores it in the course of the experiment (30 days). Over time the amylolytic activity increases. However, the intensity of metabolism of the microorganisms, the criterion of which is the ratio of the total and exogenous amylase is most pronounced in the early stages of cultivation. It was found that the culture medium of polycultures shows high amylolytic activity. This fact allows us to consider the Medusomyces Gisevii and Oryzamyces Indici inoculum as a promising biotechnological raw material source of amylase enzyme.

Abstract
The δ- and λ-variants of COVID-19 are blowing to globle economy, human life and health. The variants put the world in a harsher state. Lockdown is powerful in stopping the spread and infection. We evaluate the lockdown impact on NO2, SO2, O3, PM2.5 and PM10 in Wuhan, which reported the first COVID-19 case. Data before, during and after blokade in year 2020 were all analyzed. Lockdown significantly decreased four of the five pollutants. The decreasing reasons are discussed in social policies, people's living habits and Chinese characters. Wuhan is a transportation hub in central China. Viruses spread through it to all over the country. Although COVID-19 mainly bring bad social effects, people get chance to rethink the value of life: We should sustainablely develop and pursuing spiritual instead of excessive material enjoyment. These ultimately built more stable societies and benefit mankind itself.
