© 2015, Mediterranean Center of Social and Educational Research. All rights reserved. Activation person’s creative potential on the background of deepening democratization of social interaction is the brightest trend of society development in XXI century that stipulates transformation of practically all spheres of living environment and, above all, the sphere of education. Traditional approaches to education on every its level based on the priority of educational information transferring/uptake processes absolutely do not meet requests of intensively developing socium coming to collision with real demands of general educational services’ consumers. One of the important problems of pedagogic education in Russia is being insufficient practical training of future teachers for professional activity. In this connection the present article is dedicated to the problem of renewal of content of pedagogical training of future teacher of basic general school in accordance with new requirements to labour activity defined as Professional pedagogic standard and also to professional actions reflected in Federal state standard of general education. In the article there are model of substantial renewal of pedagogical cycle’s disciplines, improvement of their practical aspect on the basis of network interaction between educational organizations of general and higher education (school-university partnership). Authors suggest the content of “Disciplines of professional training” module and also give general trajectory for student’s actions aimed at its uptake. The represented model will be approbating in the Elabuga University of the Federal University of Kazan during 2015

Psychological-pedagogical follow-up of university students' civic consciousness formation

The author addresses the necessity of formation of civic consciousness of pedagogical university students in modern Russia. The author considers the particularities of the process of civic consciousness formation analyzed in the works of leading world specialists in the sphere of education. Relying upon the definition of civic consciousness as integrative personality feature the author identifies the components of this process. The contents, forms and methods of psychological-pedagogical follow up of students' civic consciousness formation are defined. Formation of students' civic consciousness is considered in class and out-of-class work, effective forms of this process are identified. Experimental study of students' civic consciousness formation is described. © IDOSI Publications, 2013

ГАЗОХРОМАТОГРАФИЧЕСКОЕ ОПРЕДЕЛЕНИЕ КОЛИЧЕСТВЕННОГО СОСТАВА ПИЩЕВЫХ ЭМУЛЬГАТОРОВ Е471

Nutritional supplement E471 designates number of monoglycerides and diglycerides of fatty acidsand applied in the food industry as an emulsifier-stabilizer additive. It is most often used by production of margarine, ice cream, mayonnaise, yogurts and other products with the high content of fat. The technique of gas chromatographic determination of the quantitative composition of food emulsifiers on the basis of monoglycerides (E471) was developed. The essence consists in transformation of components of sample into more flying silyl derivatives in the presence of pyridine and N-Methyl-N-(trimethylsilyl)trifluoroacetamide and the subsequent gas chromatographic determination with application of internal standards (propylene glycol and tricaprin). Theanalysis was carried out on a gas chromatograph Bruker 451 GC with a flame ionization detector, capillary column - BR-5ht (100 %-dimethylpolysiloxane). Identification of the reaction products was performed with application of a mass spectrometer Scion TQ and library of mass spectrums NIST11. Selected chromatographic conditions are characterized by a short duration of the instrument analysis (35 min) and the absence of overlapping peaks. The content of glycerin and a diglycerin, free fatty acids, mono-, di- and triglycerides in seven commercial samples is established.Keywords: emulsifier E471, monoglycerides of fatty acids, gas chromatography(Russian)DOI: http://dx.doi.org/10.15826/analitika.2015.19.2.004 A.V.

Problem-solving tasks in studying agrarian question of history of Kazakhstan

© 2017 Serials Publications.The relevance of the article is to show the problem method of training and a possibility of its application by means of introduction in process of training at lessons of history of Kazakhstan of problem and informative tasks is considered. The purpose, types and stages of work of this technology are defined. Concrete examples of tasks for pupils of 8 classes as the problem of agrarian crisis in the territory of Kazakhstan during his stay as a part of the Russian Empire is subject to consideration (the end of XIX - the beginning of the 20th centuries) are given that corresponds to program material of this age category. The importance of application of the methods aimed at independent search of knowledge and more expanded comprehension of knowledge of pupils reveals. The statå stage of experiment where the initial level of knowledge of pupils reveals is shown in article and the importance of application of problem tasks at further stages of work is proved, questions for questioning at identification of initial knowledge of a subject, and also direct steps in work on drawing up and application of similar tasks are offered. Article Submissions are of practical value for children. having entered life, the child will be more protected from stresses. Problem training forms harmoniously developed creative person capable to think logically, find solutions in various problem situations, capable to systematize and accumulate knowledge, capable to high introspection, self-development itself also corrections. Continuous setting of problem situations leads to the loss of fear by a child to face problems, a child seeks ways to resolve them, and the creative personality, always capable to search is formed

Aspen Tension Wood Fibers Contain β-(1→4)-Galactans and Acidic Arabinogalactans Retained by Cellulose Microfibrils in Gelatinous Walls

Contractile cell walls are found in various plant organs and tissues such as tendrils, contractile roots, and tension wood. The tension-generating mechanism is not known but is thought to involve special cell wall architecture. We previously postulated that tension could result from the entrapment of certain matrix polymers within cellulose microfibrils. As reported here, this hypothesis was corroborated by sequential extraction and analysis of cell wall polymers that are retained by cellulose microfibrils in tension wood and normal wood of hybrid aspen (Populus tremula × Populus tremuloides). β-(1→4)-Galactan and type II arabinogalactan were the main large matrix polymers retained by cellulose microfibrils that were specifically found in tension wood. Xyloglucan was detected mostly in oligomeric form in the alkali-labile fraction and was enriched in tension wood. β-(1→4)-Galactan and rhamnogalacturonan I backbone epitopes were localized in the gelatinous cell wall layer. Type II arabinogalactans retained by cellulose microfibrils had a higher content of (methyl)glucuronic acid and galactose in tension wood than in normal wood. Thus, β-(1→4)-galactan and a specialized form of type II arabinogalactan are trapped by cellulose microfibrils specifically in tension wood and, thus, are the main candidate polymers for the generation of tensional stresses by the entrapment mechanism. We also found high β-galactosidase activity accompanying tension wood differentiation and propose a testable hypothesis that such activity might regulate galactan entrapment and, thus, mechanical properties of cell walls in tension wood.This work was supported by the Swedish Governmental Agency for Innovation Systems, the Swedish Research Council, the Russian Foundation for Basic Research (grant nos. 15–04–02560 and 15–04–05721), and the Biotechnology and Biological Sciences Research Council (grant no.
