mechanism

Kinetics and mechanism of ligand substitution reactions on square planar platinum (II) complexes have been explored continuously over the last few decades. This was after the fortuitous discovery of the antiproliferative activity of cisplatin by Barnett Rosenberg in 1965, which attracted much attention from various other investigators to design new Pt(II) drugs with better activity and fewer side effects. Cisplatin's clinical success as a chemotherapeutic drug has promoted the discovery of succeeding generations with efficacy and less toxicity.

Purpose: Ensuring the operation of a monitoring mechanism for the use of tactical planning methods within the system of circular business models of enterprises facilitates effective resource management, waste minimization, and supports sustainable development. The formation of well-founded strategic and tactical decisions in this context is based on effective planning methods, monitoring of key performance indicators, identification of trends and changes, uncovering interconnections and patterns, etc.

The article undertakes a comprehensive examination of the theoretical and applied dimensions of the implementation of novel management technologies within enterprises engaged in foreign economic activity.

The article describes the main stages of the mechanism for managing a company's foreign economic activity based on the principles of sustainable development. The research is based on an analysis of the scientific works of domestic and foreign scientists, as well as on the practice of managing the foreign economic activity of international and Ukrainian companies.

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 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.

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 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.
