MAGNETIC PARTICLES` FORMATION IN CONDITIONS OF THE LOW-TEMPERATURE PLASMA AND MAGNETIC FIELD
01.00.00 Physical-mathematical sciences
DescriptionChemical processes are often connected with use or formation of condensed dispersed phase (CDP). Dispersed particles can change mobility of charges, as well as other parameters of the low-temperature plasma. The aim of this work is to study the effect of magnetic field on the processes of dispersed particles formation in argon-oxygen plasma containing iron and carbon atoms at atmospheric pressure. The equilibrium composition of iron and carbon atoms containing mixture simulated at temperatures of 1000-5000K for optimization of the plasma-forming gas composition. It is shown that in case of oxygen excess, the CDP particles contain only iron oxides. The literature data about the phase transition processes in a low-temperature plasma, as well as the data about the processes with participation of ferromagnetic particles in a constant magnetic field analyzed. The results of investigations of the dispersed particles forming in argon-oxygen plasma of arc discharge in the presence and in the absence of the magnetic field are shown. The formed disperse phase was deposited on the substrates and studied by the electron microscopy and X-ray methods. It was found that with the lack of oxygen the size of the iron-oxide particles created in the arc discharge containing iron and carbon is affected by magnetic field: in a magnetic field of 10 mT the particles are larger than in its absence

PHYSICAL BASIS OF ISOTOPE-ENRICHED LAYERS FORMATION IN FIBER OPTICS
01.00.00 Physical-mathematical sciences
DescriptionIt is known that transmission coefficient of quartz glass containing the same amount of 28Si and 30Si in the silicon optical fiber is lesser than in commercial LEDs for telecommunications. Therefore it is topical to develop the method of optical glass formation with specified isotope composition in the core and in the shell. The article provides an analysis of physical and chemical processes occurring at the formation of quartz optical fiber blanks by vapor deposition from the gas phase. It is shown that the part of the silicon tetrachloride oxidation stages passes through the radical processes. Therefore for quartz glass formation with specified isotope composition it is possible to use the paramagnetic phenomena caused by the external magnetic field in a high-temperature flow at the quartz glass chemical deposition from the vapor phase. In this case alloy additive using is not necessary. Alloy additives can form density inhomogeneities in the glass. Simultaneous silicon glass formation and silicon isotope separation process bring to significant reduction of the fiber cost in comparison with isotope-enriched materials using. The permanent magnets can be used for magnetic field formation at existing process units

10.00.00 Philological sciences
DescriptionThe article analyzes the particular characteristics of the logical and psychological sides of argumentation as a means of a persuasive effect in the speech of a public linguistic identity. The relevance of the research is defined by the importance of problems of studying the language of the given linguistic identities. The novelty is in the aspect of setting the problem of studying various types of public linguistic identities and in involving previously unresearched material. The object of study is a rhetorical speech portrait of a public language identity (prosecutor). The subject is particularities of logical and psychological lines of reasoning as ways of persuasive effect. The method used is scientific description with elements of speech portraying, observation. As a whole, the speech of the prosecutor corresponds to the rhetorical canons, having a standard logical composition: introduction, analysis and evaluation of the evidence gathered in the case, personality characteristics, conclusion. Various types of logical and rhetorical (psychological) lines of reasoning were distinguished in the course of the analysis. It is found that the text is rich in affective evaluation and metaphors. The general strategy is the prevalence of the psychological side of persuasive speech over the logical. The public language identity chosen strategy turned out to be successful, i.e. it made the speech expressive, original, assisting the formation of the judge's opinion in terms of conviction
