Dialogical organics of pedagogical discourse: linguo-pragmatic aspect
The article discusses the basic dialogue properties; it is particularly emphasized that the problems of studying the text, discourse and language of the operationalterminological apparatus are connected with the discursive concept of dialogis
Communicative search for a way out of the impasse in cross-cultural communication: conditions for narrowing the "gaps" between the languages
The paper addresses the issue of linguistic differences in cross-cultural communication and discusses communicative strategies that could be used to mitigate them. The authors argue that lingua-didactic multicultural education can help remove the main obstacle in the traditional teaching of Russian as a foreign language (RFL) - a "clash of cultures"; and not only can introduce a model of teaching to write, read, and speak in Russian, but can also offer a system of instruction that will allow the students to understand the way Russians think, which surely would make it easier for them to "translate" a text from one culture into another in a non-native "cultural environment" providing a polylingual format for interactio
Structure and properties of lymphocytes’ surfaces in patients with chronic lymphoblastic leucosis
In the investigation that was performed, the authors studied the structure and properties of lymphocytes’ surfaces in patients with chronic lymphoblastic leukemia with application of atomic force microscopy technology. It was stated that development of chronic lymphoblastic leukemia is characterized with circulation of immature forms of lymphocytic series in peripheral bloodstream, for which increase of surface potential by 456% (p<0.05) as compared with control group, is typica
Evaluation of the elastic properties and topography of leukocytes’ surface in patients with type 2 diabetes mellitus using atomic force microscope
The aim of study was to examine some morphometrical parameters (height, diameter) of the leukocytes (white blood cells - WBCs), their specific surface morphology (globular prominences and depression in WBCs) as well as their local elastic properties (Young’s modulus) in healthy persons and in patients with type 2 diabetes mellitus (T2DM) by means of the atomic force microscopy (AFM). Morphological and morphometrical parameters of human leukocytes were evaluated by AFM in tapped mod
Synthesis and property evaluations of highly filled polyimide composites under thermal cycling conditions from -190 °C to +200 °C
This paper presents data on the synthesis of composites based on polyimide and modified tungsten (IV) oxide (WO₂). The resulting, highly filled, polyimide/WO₂ composites were investigated by electron microscopy and thermal analysis in a gas environment of oxygen and argon. The maximum content of modified WO₂, in the studied composites, was 60 wt%. The introduction of WO₂ increases the thermal stability of the composite
Preparation of aluminum oxide coating on carbon/carbon composites using a new detonation sprayer
A new multi-chamber cumulative detonation sprayer (MCDS) was applied to fabricate an aluminum oxide coating on carbon/carbon composites. MCDS provides heating and acceleration of ceramic micropowders by means of combustible gas mixture detonation products with a frequency of 20 Hz and above. The ceramic aluminum oxide particle kinetic energy ensures the destruction of the weakened areas on the carbon-carbon composite material surface and the incorporation of these particles into the surface layer. The following powder particles decelerate on the already fixed particles and form a ceramic coating. The formed aluminum oxide coating is characterized by high hardness and low porosity (<1%). MCDS provides the formation of a high-quality ceramic layer, which can also serve as the basis for the formation of protective heat-resistant coating
НЕЙРО-СЕТЕВОЕ МОДЕЛИРОВАНИЕ В ЗАДАЧАХ ПРОГНОЗИРОВАНИЯ РЕЖИМОВ РАБОТЫ ЭЛЕКТРИЧЕСКИХ СЕТЕЙ
Purpose. Form a neuro-fuzzy network based on temperature monitoring of overhead transmission line for the prediction modes of the electrical network. Methodology. To predict the load capacity of the overhead line architecture provides the use of neuro-fuzzy network based on temperature monitoring of overhead line. The proposed neuro-fuzzy network has a four-layer architecture with direct transmission of information. To create a full mesh network architecture based on hybrid neural elements with power estimation accuracy of the following two stages of the procedure: - in the first stage a core network (without power estimation accuracy) is generated; - in the second stage architecture and network parameters are fixed obtained during the first stage, and it is added to the block estimation accuracy, the input signals which are all input, internal and output signals of the core network, as well as additional input signals. Results. Formed neuro-fuzzy network based on temperature monitoring of overhead line. Originality. A distinctive feature of the proposed network is the ability to process information specified in the different scales of measurement, and high performance for prediction modes mains. Practical value. The monitoring system will become a tool parameter is measuring the temperature of the wire, which will, based on a retrospective analysis of the accumulated information on the parameters to predict the thermal resistance of the HV line and as a result carry out the calculation of load capacity in real time.В статье сформирована нейро-фаззи сеть с учетом температурного мониторинга воздушной линии.

Synthesis of PI/POSS nanocomposite films based on track nuclear membranes and assessment of their resistance to oxygen plasma flow
This work presents, for the first time, data on the possibility of synthesizing polyimide nanocomposite films based on track nuclear membranes and organosiloxane (polyhedral oligomeric silsesquioxanes) POSS structures. The synthesis of the nanocomposite films was carried out by filling the tracks of a polyimide membrane with POSS structures under hydrothermal conditions in a high-pressure reactor. The surface and mechanical characteristics of the developed nanocomposite films were studied, and the results of their resistance to the flow of oxygen plasma are presente
