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)3Ð=N-Cар (Ð=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As
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

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
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
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
