ABOUT COMPARATIVE POLARITY OF As=N AND P=N GROUPS

abstract 0781204019 issue 78 pp. 222 – 233 30.04.2012 ru 1851
By the method of the dipole moments the connections of (p-XC6H4)3As=N-C6H4-Y series have been examined. The method of the vector-statistical analysis of the dipole moments helped to define the ranges and directions of the moments of (Сар)3As=N-Cар, (Сар)3As=N и N-Cар series. There has been shown that the substitution of the para-assistants X and Y in aromatic groups doesn't lead to an additional interaction influencing the electronic properties of the (Сар)3As=N-Cар group. The comparative analysis of the (Сар)3Э=N-Cар (Э=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As

ABOUT AN INTERACTION OF 3-AMINOTHIENO[2,3-b]PYRIDINE-2-CARBOX-AMIDES WITH AROMATIC ALDEHYDES UNDER CONDITIONS OF ACID CATALYSIS

abstract 1111507039 issue 111 pp. 695 – 707 30.09.2015 ru 1215
The present article belongs to the area of organic chemistry, namely, to chemistry of heterocyclic compounds. For the purpose of optimization of a method of synthesis the threecyclic heteroaromatic systems containing a pyridi-ne, thiophen and pyrimidine ring in one molecule, - tetrahydropyridothienopyrimidinon and dihydropyri-dothienopyrimidinon – reaction 3-aminothieno[2,3-b]-pyridine-2-carbokxamides with aromatic aldehydes is studied, some of which contain pharmacolodical groups. Reaction was carried out in the conditions of an acid catalysis – is used p-TsOH. Influence of the nature of solvent (toluene, ethanol, mix ethanol-dimethilform-amide (1:1)) on the course and the direction of reaction are studied. It is established that carrying out reaction in toluene leads to the dihydropyrimidine containing in situation 2 phenyl, 4-bromphenyl deputies. In the presence in a molecule of initial aldehyde of the deputy in orto-situation tetrahydropyrimidine are formed. Use of ethanol mainly leads to formation of a tetrahydro-pyrimidine ring. Boiling of initial substances in mix ethanol-DMF yields the results similar to use of toluene, but time of reaction is reduced twice. The way of receiving the dihydroderivatives short-term boiling of tetrahydropyrimidine is found in mix isopropanol-DMF (a volume ratio of solvents 1:3). Identity of the received substances is proved by method of a thin layer chroma-tography. The structure of the synthesized connections is confirmed with the element analysis. The structure of tertagidropirimidinon and digidropirimidinon is proved with use of data of IK and NMR 1H of the spectral analysis

ABOUT A VARIETY OF MEDIA GENRES IN MODERN RUSSIAN AND FOREIGN JOURNALISM

abstract 1151601062 issue 115 pp. 999 – 1008 27.01.2016 ru 837
The article deals with media genres in Russian and foreign journalism in the conditions of modern realia. The researches of this sphere find some reasons, caused by different approaches and criteria existing in different language systems as in Russia, as in abroad. The author of the article has been studying scientists’ works to point out some definitions of genres. In Anglo-American journalism genres have the category of sub-genres, including news report, the news interview, or the news headline. It is also pointed out that with the development of new information technologies many journalistic genres loose its timeliness. They are sketch, satirical article, editorial, press review, other (interview, comment, essay) – in the contrary, increase its existence. New genres are noted, among them are journalistic investigation, confession, version, conversation, press release. In spite of the variety of genres, theorists note their irregularity and migration from one sphere into another (lecture, debates, cross examination). Among all, there are new genres such as Rapinfo – news in patter and fatics which helps to contact with reader, forge and boost links with audience

ABOUT A QUESTION OF SELFORGANIZATION IN DEVELOPING SYSTEMS

abstract 1071503026 issue 107 pp. 374 – 383 31.03.2015 ru 1160
The problem of transition from the abstract and general dialectics to the concrete and common theory of development, the problem of diachronic of dialectic and synergetic cognition’s culture in the context of comporation between the philosophic and natural science are discussed in the article. The hypothese of cosmologic singularity the birth of tte world from «nothing» and the role of «dark materia» in the developing’s process of our Universe are also described. The author points out on the features of synergy, which using the linearity аnd nonlinearity in the theory expresses the aspects of material unity of the world, linked to the general properties of self-development of complex systems. The universe is seen as a dissipative system with periodically removable elements (elementary dissipative systems). The spontaneous disbalance of symmetry and the appearance of new physical forms of existence are characteristic for the elementary parts. The order? The symmetry and the spontaneous disorder in the symmetry are the phenomena of self-organization of the material. The scientific results which we found with the quantum theory of field, can give us the theoretical descriotions of such forms of existence that’s why the structural unity in all levels of materia can be explained in the quantum and field image of the world

ABOUT A QUESTION OF DEVELOPMENT OF MICRO-, MACRO- AND MEGAWORLD IN THE POSTNONCLASSIC ONTOLOGY

abstract 1331709012 issue 133 pp. 124 – 133 30.11.2017 ru 739
In the article, we discuss a possible institutionalization of postnonclassic ontology. It is shown that the nonlinearity, deterministic chaos, fractality phenomena change classic views on possible forms of existence, cause of nature. The work discusses conceptual foundations of the particle physics. This theme is examined in connection with problem of logical and philosophical analysis of physical language and its usage in cognitive procedures. The article refines the modern model of three-component structure of the Universe on the basis of post-nonclassical consideration of the Universe. Features of synergetic as interdisciplinary scientific direction, the concept of a universal evolutionism, value of information in nature development are discussed. Methodological basis of the process of integration of scientific knowledge is the interdisciplinary direction of the research which important component is the synergetic. It plays an important role in the concept of coevolution realization which considers mutual relation of the person and the nature, the micro- and the megaworld. The article demonstrates that having revealed the laws of functioning of complexly evolutionizing, nonlinear systems, synergetic thus posed the fundamental questions of both epistemological and ideological and value nature. Conceptual shifts occurring in cognition open up the new sides in the interpretation of not just order and disorder but also the categories they generate
