Документ Theoretical calculation of the activity coefficients of dilute aqueous solutions taking into account factors of electrical nature(2022) Kravchenko, M.; Bereznytska, Y.; Vasylenko, L.; Fedorenko, S.The work is devoted to development of the diluted water solutions activity coefficient calculation methodology, using the equalization of the self-agreed systems continuum electrodynamics and allocating processes which are characteristic for the electric system. The dependence of calculated ion activity factors on concentration of diluted water solutions, which are divided into three groups, was obtained. It is justified that for single- and two-valent electrolytes of the first group the influence of the general mechanism of interaction between ions is characteristic, which is determined by the action of ion electric gravity and it`s features. The growth of activity in the area of large concentration values for electrolytes containing hydrogen ion and lithium ion is shown. It has been found that the activity values in the area of electrolytes large concentrations increase is connected with the manifestation of forces of pushing electrical origin in processes, which are accompanied by redistribution of charges. On the basis of equalization for the dielectric component properties of electrolytes water solutions are described. The dependence for calculation of electric field potential, field strength and charge density were obtained. Given the change of diluted water solution internal energy for "i" class ions and free energy is obtained the expression for chemical potential ions. The calculation of the diluted water solutions activity average coefficient is proposed taking into account the nature of electric factors.Документ Environmental management as a component of Ukraine’s modern economy: Management under the conditions of martial law(Construction of Optimized Energy Potential (CoOEP), 2022) Fedorenko, Stanislav; Vasylenko, Lesya; Bereznytska, Yuliia; Kravchenko, MarynaThe development of environmental management in Ukraine is determined by the urgent need to overcome environmental problems and ensure the environmental safety of society, especially under the conditions of martial law. Today, the domestic economy is three times more resource-intensive than the world economy, the technological base and infrastructure complex of public production are rapidly wearing out, which leads to a decrease in the level of technological and environmental safety. Environmental management is related to the national economy and forms information about the need to use natural resources when promoting effective development. A comprehensive project-targeted approach to the develop ment of new forms of ownership and market economy reflects the interrelationship of all parts of the nature management project. The development of the scientific foundations of nature management is facilitated by the formulation of a general plan for the placement of productive forces. The ecological situation in Ukraine has long been called a crisis. In recent decades, new scientific directions have appeared, the result of which have been new ideas about human, society and nature and their coexistence. One of these directions is environmental management, which today is the ideology of production activity manage ment, as it provides an effective toolkit for solving current problems and preventing the emergence of new production environmental and economic issues.
