Synthesis and Attestation of Titanium Dioxide Nanotubes Based Photocatalyst for Water and Air Purification out of Harmful Organic Impurities

In the present work we have synthesized nanotubular TiO2 film with a nonstoichiometric layer in the vicinity of titanium foil by anodization during 120 min. The catalytic activity of nanotubular titanium dioxide films formed during the oxidation of acetone to carbon dioxide under the action of visible light with a wavelength of 450 nm was found to be approximately 2 times higher compared to standard titanium dioxide (Degussa P25). Such a pronounced enhancement of activity may be attributed to a more efficient absorption of visible light by the films due to narrowing of the optical gap because of difference in the nonstoichiometry of titanium dioxide near the interface between nanotubular film and the titanium foil substrate. Keywords: photocatalysis, nonstoichiometric titanium dioxide, purification of wate

Rhetorical Lacunes: Causes, Implications, Warning

The article analyzes the current state of rhetoric as an academic discipline and the prospects for its study. Rhetorical skills and skills of the student are one of the significant results of educational achieve­ments. However, in Russia, their formation is hampered by the absence of the majority of native speakers of ideas about the logical, stylistic and ethical laws of public speech. Purpose of article - based on the analysis of works devoted to modern rhetoric, to characterize the state of rhetorical education in modern society and the place of rhetorical (communication) disciplines in the system of school and university education. The causes of the decline of rhetoric, the ways of its development as a factor in the education of a rhetorical person are considered, the problem of speech influence and its study in a higher educational institution is touched upon.В статье рассматривается современное состояние риторики как учебной дисциплины и перспективы ее изучения

The Small-angle X-Ray Scattering Investigation of Advanced Beryllium Materials

The small-angle X-ray scattering (SAXS) technique allows to determine size distributions of inhomogeneities in materials and to predict their properties in Xray optics devices. A number of beryllium materials for the manufacturing of X-ray optics (refractive lenses and speckle suppressors) have been studied by the SAXS.Various composite materials based on porous beryllium have been studied. The effect of adding detonation nanodiamonds to the beryllium matrix on the scattering ability of the material is discussed. Keywords: porous beryllium, SAXS, detonation nanodiamonds, speckle-suppresso

Expression of Integrins, Anchorage Dependent Apoptosis and Invasiveness of Multidrug Resistant Human Breast Carcinoma Cells

The aim of the study was to investigate the role of integrins in anchorage dependent apoptosis (anoikis) and in vitro invasion of human breast cancer cell line MCF-7 and its multidrug resistant subline MCF-7Dox. Acquisition of MDR was associated with markedly decreased expression of collagen specific a2ß1 and avß3 integrins, laminin specific a3ß1 and a6ß1 receptors and dramatic up-regulation of fibronectin specific a5ß1 integrin. The MDR subline was substantially more resistant to anoikis than their wild type counterparts. Furthermore, MCF-7Dox cells secreted MMP-9 collagenase and invaded Matrigel. We demonstrate for the first time that stimulation of ß1 integrin signaling strongly sensitizes MCF-7 cells to anoikis

NORMATIVE ORIENTATION OF THE LANGUAGE OF FICTION: LINGUISTIC-AESTHETIC ASPECT

Purpose: The article conducts the study implementation of the normative orientation of the language of fiction: linguistic-aesthetic aspect Methodology: This is analytical-logical research done by content analysis. Result: In the article, it is argued that normative orientation of the fiction speech is rather different from that of functional styles in which, as a rule, not only non-literary language elements but also specific phenomena of other styles are not used. Applications: This research can be used for the universities, teachers and education students. Novelty/Originality: A number of outstanding scientists such as V.D. Levin, N.A. Meshchersky, N.M. Shansky, N.L. Maksimov, D.N. Shmelev, K.A. Panfilov and others consider the language of fiction as a special type of the literary language which is characterized by aesthetic function and in which the particular peculiarities of all other functional styles can be found as well as non-literary linguistic means of different kinds: colloquial, slang, dialectal, etc

An educational technology for developing professionally-oriented EFL communicative competence: its acmeological potential

AbstractThis paper addresses the problem of creating effective educational technologies aimed at developing university students’ professionally-oriented EFL communicative competence in research-oriented higher educational settings. Two techniques (mini-research and individual educational trajectory), being actional components of the educational technology developed, were analyzed from the acmeological potential perspective based on the study undertaken. The study participants were undergraduates and master's students majoring in non-language-related fields
