Effect of the Polyester Fibre Content in a Blend with Thermostable Fibres on the Flameproofing Indexes of Manufactured Materials

Abstract: Thermolysis processes were investigated and the flameproofing indexes of fabrics made from blends of thermostable Nomex and SVM fibres with polyester fibres were determined. It was found that difficultly flammable materials can be fabricated in the Nomex composite with a 20-25% polyester content and in the SVM composite with a 35-40% polyester content.

Composition and submicron structure of chemically deposited Cu 2 Se-In 2 Se 3 films

Abstract: Films of substitutional solid solutions of the Cu2Se-In2Se3 system containing up to 7.5 at. % In have been obtained by chemical deposition from aqueous media. The composition, structure, and morphology of the films have been studied. Data of X-ray diffraction and X-ray photoelectron spectroscopy showed that copper in the solid solution occurs in a single-valence state (Cu+). The deposited layers possess a globular morphology and are nanostructured.

Specific features of the combustion of hydrogen-oxygen mixtures near the lower concentration flammability limit

Abstract: The combustion of hydrogen-air mixtures near the lower composition flammability limit in cylindrical reactors of various diameters is studied. The speed of flame propagation in the horizontal direction is lower than that in the upward direction. Chromatographic analysis showed that, during the combustion of these mixtures, hydrogen is consumed only partially. That the flame propagates despite a low adiabatic temperature can be explained by the formation of the well-known cellular structure.

Effect of the Substrate Nature on the CdPbS Film Composition and Mechanical Stresses at the “Film–Substrate” Interface

Abstract: The role of substrates of different natures on the phase composition, morphology, and mechanical stresses at the “film–substrate” interface during the chemical deposition of CdPbS layers on silicon (111), glass ceramics, fused quartz, an indium–tin–oxide (ITO) coating, slide glass, and porous glass is studied. It is assumed that the revealed features are associated with different conditions of film nucleation and growth. It is found that a single-phase CdxPb1 – xS solid solution film is formed on fused quartz, in contrast to other substrates on which layers containing additionally from 2 to 8 mol % of the X-ray amorphous CdS phase are deposited. It is shown that an increase in mechanical compressive stresses at the “film–substrate” interface from –9.32 to –121.79 kN/m2 in the series porous glass–object glass–glass ceramics–silicon (111)–fused silica is asymbatic to the thermal-expansion coefficients of these substrate materials.

Sociological Analysis of Labor and Intellectual Migration of Young People in the Knowledge Economy

Abstract: Fundamental sociological theories of migration study reveal the motives for an individual’s and households’ making decision to migrate, as well as the social factors and consequences of the unfolding of migration processes. Structural changes taking place in society caused by both the innovative nature of economic growth as a whole and the digitalization and expansion of information and telecommunications technologies imply the perception of the phenomenon of migration not only as a territorial movement of the population in space for a long period. Digitalization and development of remote forms of work, in particular, reduces the need for physical concentration of human resources, which allows people to choose the most comfortable places to live. Special attention is paid to the Diaspora, which is one of the important tools for solving communication difficulties. The sociological analysis of migration processes in Armenia illustrates the application of the main concepts, in particular, networked migration and reliance on the Diaspora.
