Theory of continental drift – causes of the motion. Outline of the theory

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.

Compositions of Arylalicyclic Copolyimide with Alkylated Monthmorillonite

The results of studies on the preparation and study of the properties of composite materials based on compositions of arylalicyclic copolyimide and alkylated montmorillonite (AMM) modified with polyethylene glycol to increase the affinity of a natural mineral to polymer matrix are presented in the work. It was found that an increase in the compatibility of composition’s components is due to the addition to copolyimide solution of previously prepared mixture of alkylated montmorillonite in 5 % and 2 % polyethylene glycol solution in methylpyrrolidone.

Theory of continental drift – causes of the motion. Historical review and observations

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.

Principles and the mechanism of state regulation of the economy

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.

Modification of the Catalytic System for the Industrial Chlorine Processing of Ethylene in 1,2-Dichloroethane

A new mechanism for the reaction of direct (additive) chlorination of ethylene with chlorine from the formation of 1,2-dichloroethane in the presence of FeCl3 catalyst promoted by NaCl has been proposed. It was found that the rate depends on the active phase concentration of the catalyst and the promoter, as well as the formation of the Na[Fe(C2H4Cl)4] complex, which is a surface intermediate of the reaction.

Concept of administrative and legal support and its mechanism

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.

Spectrophotometric Determination of Ruthenium Utilizing its Catalytic Activity on Oxidation of Hexacyanoferrate(II) by Periodate Ion in Water Samples

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).

Kinematics of the mechanism of shelf attachment of elevator shelving

The structural design of the mechanism of stabilization of horizontal position of the shelf of elevator shelving with a chain drive is proposed. The analytical dependencies for determination of the motion trajectory of supporting and guiding rollers of the shelf supporting mechanism are derived. The formulas for defining the horizontal and vertical displacement of the center of the arc of the trajectory of the guiding roller relative to the center of the driving star of the chain transmission during the shelf passing through the "characteristic" regions are presented.
