“…It is enough to differentiate (25) and equate the derivative to zero to find the temperature, at which the maximum entropy is realized. It seems impossible to analytically determine the position of this maximum due to the difficulty of freeing the temperature from the resulting transcendental equations; therefore, this temperature Smax T was determined numerically for all metals, for which reference data are available [11]. In general, the formation of the function maximum (24) is necessary, since these functions take zero values both at T = 0 and at T ⟶ ∞ due to presence of only one kind of particles at this value, respectively 1 crm P  and 1 vm P  , due to which all fragments of equation ( 24) are zeroed both by the condition 1ln1 0 …”

The authors of the article have developed the concept of chaotic particles based on the Boltzmann distribution over the kinetic energy of the particles’ chaotic motion. This distribution allows to combine the solid, liquid, and gaseous states of matter with the help of energetic particles called crystal-mobile, liquid-mobile, and vapor-mobile. The ratio of the proportions of such randomized particles determines a certain state of matter aggregation. The sum of the shares of these particles in all combinations at any temperature is equal to unity. During the study it has identified that qualitative and quantitative analysis of states with a priority basic effect of a randomized component of a substance can be conducted. Certain regularities of states were discovered, independent of the specific type of substance and consistent with the physicochemical properties. The entropy of mixing of all three energy classes of chaotic particles was calculated for simple substances. It was characterized by a maximum in the interval of the boiling point of substances. This feature testifies to the unique variety of possibilities for the implementation of the most complex heterogeneous processes in terrestrial conditions at atmospheric pressure, which ultimately ensured the self-organization of life

It is known that after being infected with phytoviruses plants do not recover. Breeding virus-resistant cultivars also does not give reliable results due to the high variability of pathogens and their diversity. And since it is impossible to obtain stable forms then one of the goals of protection a virus-free material and preventing its re-infection. To improve the health of vegetative propagated plant species, you can use the method of tissue culture of the apical meristem. In some cases true seeds can be healed by thermal or chemical treatment. The data on viruses infecting the main agricultural crops of the Russian Far East are presented; the features of their distribution and interaction with plants are described. Possible measures are given to prevent of phytoviruses spreading and re-infection of virus-free plants in the process of breeding and seed production, in gardening and landscape design.

This paper is the review of literature data on the prevalence of weeds as possible reservoirs of plant viruses in agroecosystems of Ukraine. The information presented here about the most distributed weeds as reservoirs of harmful plant viruses will be useful for understanding the pathogens ecology, analyzing the virus epidemiology and for disease management. Since legumes are the main crops grown in Ukraine, the paper focuses on weeds spreading in the agrosystems of cultivated plant. The paper provides information about the primary sources of soybean viruses (Soybean mosaic virus, Cucumber mosaic virus, Alfalfa mosaic virus, Tomato ringspot virus) and bean viruses (Bean yellow mosaic virus, Bean common mosaic virus) as well as the main factors contributing the virus transmission in agrocenosis.
