The theory of mantle convection currents as the cause of lithospheric plate movements has several major problems, including the absence of an adequate energy source. As shown in our previous contribution, an unbiased interpretation of geochemical data does not support the assumptions of a significant amount of radionuclides in the lower mantle or even in the core. It is our assertion that solar radiation is the primary energy source in the lithosphere. This energy is converted into mechanical energy via thermoelastic waves, even in depths with minimal temperature fluctuations.

The theory of continental drift was published as early as 1912, but the mechanism and energy source of this motion has not yet been elucidated. In many cases, the generally accepted model of convection currents in the mantle contradicts observations such as the spreading of the ocean floor, the extension of rifts from triple points to all  sides, the more or less unilateral movement of the lithosphere relative to the mantle, and others.

The dynamics of the adsorption process in the fixed-bed column was experimentally studied on the example of the system natural zeolite - water solution of copper salt with low concentrations, which are characteristic for wastewater treatment processes from toxic contaminants. The initial curves of the adsorption process for the height of the sorbent layer of 5 and 7 cm were constructed. The equilibrium of such processes can be described by Henry's linear equation. The adsorption process in the layer consists of two stages, which are examined in the study.

The major issues concerning principles and the mechanism of state regulation of the economy as a part of the mechanism of state regulation are considered. The contents of the mechanism of state regulation of the economy on the basis of studying the mechanism of public administration, the etymology of the word “mechanism” with the nature of the state regulation of the economy are revealed. The component structure of the mechanism of state regulation of the economy is defined and its components are revealed and characterized.

The article analyzes the principles of development and security management of the foreign exchange market of Ukraine.

The topicality of the article is due to the need for scientifically substantiated definitions of the concepts of administrative and legal support (hereinafter referred to as ALS) and its mechanism, the formulation of which is its purpose. A systematic approach, methods of analysis and synthesis, expert assessments were used in the process of realization of the article purpose. The analysis of a number of views on the essence and structure of administrative and legal support has been done.

The catalytic effect of ruthenium chloride on the outer sphere electron transfer of hexacyanoferrate(II) by periodate ion in aqueous alkaline medium has been effectively employed to determine ruthenium(III) at micro level. The optimum reaction condition has been established and fixed time procedure is adopted. A linear relationship between changes in absorbance and added Ru(III) concentration has been utilized for the trace level determination of Ru(III).
