Analysis of the scientific literature shows that data on nitrogenous derivatives of ketoaldehyde and ketoesters, their synthesis, tautomerization and Complexing ability are incomplete, in some cases their coordination compounds remain abstract, which requires special attention. As a result of the study of the electronic and spatial structures of the complex molecules, it became possible to determine the causes of the "composition-structure-properties" relationship of chemical compounds in a much more complex structure. The structure and tautomerization of para-exchange acylgases of ethyl ether of 2,4-dioxopentanoic acid in various solvents are studied in the article. role of Stephen Krashen's ideas in the theory of second language learning

This article identifies and presents the generalized difference (g-difference) of fuzzy numbers, Fréchet and Gâteaux generalized differentiability (g-differentiability) for fuzzy multi-dimensional mapping which consists of a new concept, fuzzy g-(continuous linear) function; Moreover, the relationship between Fréchet and Gâteaux g-differentiability is studied and shown. The concepts of directional and partial g-differentiability are further framed and the relationship of which will the aforementioned concepts are also explored. Furthermore, characterization is pointed out for Fréchet and Gâteaux g-differentiability; based on level-set and through differentiability of endpoints real-valued functions a characterization is also offered and explored for directional and partial g-differentiability. The sufficient condition for Fréchet and Gâteaux g-differentiability, directional and partial g-differentiability based on level-set and through employing level-wise gH-differentiability (LgH-differentiability) is expressed. Finally, to illustrate the ability and reliability of the aforementioned concepts we have solved some application examples.

Many derivatives of 2,3-dim ethoxy-4-hydroxypyridine, which were designed from examination of the structure-activity relationship of piericidins, were tested for inhibition of NADH-UQ reductase. The lipophilic side chain of those compounds was indicated to be a key part for activity and its optimal length was conjectured. By the use of two different phases of assay material, intact mitochondria and submitochondria, the size of a membrane effect was shown to depend on the structure of the side chain. 4-Hydroxyquinoline derivatives were also tested for an analogous role in relation to the electron transport function of menaquinone, and they were proven to be inhibitors of NADH-UQ reductase as good as the pyridine derivatives.

For the last twenty years, polymer hybrid nanocomposites have enjoyed unflagging interest from numerous scientific groups and R&D departments, as they provide notable enhancement of properties, even at low nanofillers’ content. Their performance results from many factors, the most important of which is the uniform distribution in the entire volume of the matrix, that still is very challenging, but is the right choice of two types of nanoparticles that can lead to an increase of dispersion stability and even more uniform distribution of fillers. The incorporation of two types of nanofillers, especially when they differ in aspect ratio or chemical nature, allows to additively reduce the price of the final composite by replacing the more expensive filler with the cheaper one, or even synergistically improving the properties, e.g., mechanical, thermal, and barrier, etc., that can extend their usage in the industry. Despite numerous review papers on nanocomposites, there is no review on how the introduction of a hybrid system of nanofillers affects the properties of polyolefins, which are the most commonly used engineering plastics. This review deeply focuses on the structure–properties relationship of polyolefins-based hybrid nanocomposites, especially based on two types of polyethylenes (low-density polyethylenes (LDPE) and high-density polyethylenes (HDPE)) and polypropylene.

Phenothiazone has been found to be a strong inhibitor of glyoxalase activity of human and rabbit erythrocytes. Concentrations for 50% inhibition were 10−6 M for intact cells and 10−4 M for haemolysates with added glutathione. Glyoxalase activity was also markedly inhibited by phenothiazine, methylene blue, and p-chloromercuribenzoate; slightly inhibited by alloxan and phenylhydrazine; and not affected by dialuric acid. Enzyme inhibition did not parallel methaemoglobin formation. The possible relationship of these findings to the haemolytic action of phenothiazine is discussed.
