Lifelong learning as an actual strategy of higher professional education modernization in Russia (in case of speech therapy teachers' training)

This article describes the main lines of implementation of the new strategy of development of the higher professional education - "lifelong learning" - within the framework of formation and development of the contemporary model of a higher education institution, the primary task of which is integration of education into science and production, and its orientation to the globalizing international labor market. Stating that in Russia, like in the leading European countries, the paradigm of lifelong learning is a strategic line of the education policy, the authors provide a constructive analysis of the educational activity of the Institute of Pedagogy and Education of the Kazan (Privolzhski) Federal University, which is an innovative center of technological development of the region implementing the primary task of integration of education, self-education, and research activity of students based on the analysis of the social order and requirements of the international education market within the framework of competent specialists training

Magnetic microstructure of oxygen-deficient perovskites

Samples of oxygen-deficient perovskites were studied by means of Mossbauer spectroscopy. The Mossbauer spectra were obtained at room temperature. X-ray data confirmed the ordered distribution of iron and copper deduced from Mossbauer spectroscopy data

Investigation of the cation distribution in perovskite-like oxides with mössbauer spectroscopy

Complex perovskite-like oxides, such as LnFe(2/3)Mo(1/3)O"3 orthoferrites, Ln(8 -) ySryCu(8 -) xFexO"2"0 (8-8-20), Pr"4BaCu"4FeO(13 - δ) (4-1-5), YBa(2 -) yLayCu(3 -) xFexO(7 - δ), and Y(1 -) yCayBa(2 -) yLayCu(3 -) xFexO(7 - δ) (1-2-3), are studied by means of Mössbauer spectroscopy. At room temperature, the spectra of the orthoferrites contain only magnetic components. The spectra of the 1-2-3 compounds contain only magnetically disordered components: iron atoms substitute for copper at Cu(1) sites, taking various configurations: planar squares, quadratic pyramids, and octahedra. Cuprates 8-8-20 and 4-1-5 have a wide diversity of spectra. In the 8-8-20 oxides, a phase related to the pyramidal environment of the iron cations is present at any iron concentration. In all the perovskites, iron cations become magnetically ordered only at octahedral sites of the structure. © 2005 Pleiades Publishing, Inc

Utilization of inorganic industrial wastes in producing construction ceramics. Review of Russian experience for the years 2000–2015

© 2016 Elsevier LtdThis paper analyzes the significant scientific publications worldwide for the last 15 years concerning construction ceramics (predominantly brick) made with various inorganic industrial wastes added to the ceramic raw material for the improvement of properties and for eco-friendly disposal. The information gap resulting from the lack of mentions of the Russian publications on this subject in English-language reviews is filled. The paper includes brief summaries of 34 dissertations and 29 patents issued in Russia since 2000. The waste additives described in these summaries are grouped by origin type (mining industry waste, ore enrichment waste, metallurgical waste, sludge, ashes, cullet, large-capacity building wastes and waste from various chemical production processes) with the ceramic mixture compositions, molding and firing conditions, final strength, water absorption and other parameters of the final ceramic samples reported. Russian scientists have expanded the nomenclature of each group of wastes significantly upon addition to the list described in English-language reviews for 2000–2015. References to the recent Russian developments in the field of ecological management in ceramic industry are provided

Mössbauer study of some perovskite-related oxides

Complex perovskite-related oxides with various structure types: orthoferrites, 4-1-5, 8-8-20, and 1-2-3 were studied using Mössbauer spectroscopy. Correlations between magnetic ordering of iron atoms and their structural coordination, as well as between oxygen deficiency and iron ion valence, were found. © 2006 by Allerton Press, Inc

Magnetic microstructure and the electrical properties of rare-earth Fe-substituted cuprates of the 8-8-20 type

Crystal structure, magnetic microstructure, and electrical properties of cuprates of rare-earth elements with a partial substitution of the atoms of strontium for rare-earth elements (REEs) and iron for copper have been investigated. The detailed analysis of the Mössbauer spectra of cuprates made it possible to assume that the substitution of strontium for REEs in iron-substituted cuprates of neodymium leads to a recharging of part of iron cations, and in praseodymium cuprates, of lanthanide ions. The measurements of electrical conductivity and thermopower of the samples confirmed this assumption. © 2007 Pleiades Publishing, Ltd

Mössbauer investigations of magnetic system stratification in europium and thulium ferromanganites

Strontium-substituted ferromanganites of europium and thulium were investigated. Samples of Eu0.65Sr0.35Mn 1-xFexO3 and Tm0.65Sr 0.35Mn1-xFexO3 were prepared using ceramic processing. Based on the data from X-ray analysis, the samples with europium had a perovskite lattice, whereas the thulium samples were crystallized in an ilmenite lattice. Stratification of the magnetic subsystem was observed in the Mössbauer spectra of certain samples at T ≈ 300 K. © Allerton Press, Inc., 2010
