Social Meaning of Culture in a Stalinist Prison Camp
Реферат: The Stalinist prison camp system - popularly known as the Gulag archipelago - existed for a relatively short period (from 1931-1960) and became world famous as a synonym for terror, humiliation and human suffering. This article focuses on the social significance of culture in one of the biggest Stalinist prison camp - Karlag in Central Kazakhstan. The first part of the article gives an overview of the institutions of culture in prison camps and their activities. It also gives an overview of unofficial cultural activities and the consequences of being engaged in the unsanctioned creation of art. In the second part of the paper, the social significance of culture in Stalinist prison camps is discussed. Official and non-official art were not separate and existed in symbiosis: people crossed the border between these spheres. Moreover, the camp administration recognised the material value of art produced in the camp and began to organise the production of pictures or handicrafts in order to sell them outside the camp. Nevertheless, both official and unofficial cultures had a deep social meaning for the people. Producing unsanctioned paintings and other objects of artistry can be seen as an act of resistance, producing sanctioned art helped the artists to create their own social and mental space and distance themselves from the everyday grind of the camp. In general, culture and its institutions in the prison failed to fulfill their original purpose - instead of re-educating and changing inmates, culture helped to maintain human dignity and integrity.

Реферат: Computer simulation of the properties of the crystal lattice gives to use up to 1010-1012 atoms. Using the described technique can be obtained from any of these atomic systems, as well as changes in the radii of coordination spheres at various distances. Simultaneously, you can get a number of nearby neighbors, the location of atoms on the coordination sphere. The initial structure is taken compound GaAs. The resulting model is given for different distances from the central atom. There are the distances from one to six. The result is an uneven growth of the number of atoms grouped along the radius of coverage. For the other elements of the possibility of uniform methods increase the number of atoms, such as Ga. We can develop an algorithm for constructing the structure of compound semiconductor-type A3B5, based on this principle. For example, to the type of A3B5 of semiconductor compounds it is used compound GaAs.

Реферат: Speech (word) culture is one of the branches of linguistics, dealing with the study of word-use correctness in accordance with language norm. Teaching this course is an actual problem connected with increase of students\' intellectual and cultural level and bringing up of linguistic personality. For developing students\' speech culture it is necessary to create the following conditions: leading principles of developing oral speech, productive methods and ways, communicative approach to teaching process, rational organization of lesson, students\' orientation towards independency in doing tasks, didactical materials, meeting certain requirements, system of exercises and technical equipment. All mentioned above must be directed to the development of students\' speech culture.
Impact of energy saving cultivations on soil parameters in northern Kazakhstan
Реферат: Recently the cost of soil processing for agricultural production has been rapidly increasing because of expensiveness of agricultural machinery, energy, and agricultural chemicals. Intensive soil cultivation is costly and adversely affects soil fertility due to accelerated mineralization of soil organic matter. By minimizing mechanical disturbance to the soil, costs can be reduced and the enviroment enhanced. About half of the global CO2 emissions from the soil come from decomposition of the annual plant litter including agricultural crops. We studied methods of soil tillage that help stabilize the yield of crops while maintaining soil fertility and saving energy and labour at the same time. Three types of crop cultivation experiments were studied: 1) cultivation intensity (simplified ST, common CT, and intensive IT): 2) tillage depth (shallow S, and deep D subsoil till), and 3) minimum MT, and zero till ZT. The results showed that under ST the soil biological parameters were more favourable than under CT and IT. Shallow subsoil till maintained higher levels of soil nutriens, and reduced CO2 emission compared with the deep subsoil till. The minimum and zero tills positively influenced soil physical and biological through improvement in soil aggregate stability and soil enzymatic activity.
Karst and Pseudokarst of the West Kazakhstan (Republic of Kazakhstan)

Реферат: An analysis of the formation of karst and karst-suffosion forms on the territory of the West Kazakhstan region is presented in this paper. Numerous literary sources were used as the information database for the analysis of the relief features of the West Kazakhstan region. Evaluation of the morphometric features of the collapsed new formations on the basis of materials of our own field research is presented here for the first time. According to the research objectives there were defined localization places of the karst-collapsed phenomena where the reconnaissance field surveys were carried out. Survey points\' localization has been carried out by means of GPS system with the help of 12-channel GPS-receiver of Garmin eTrex model. Geoinformational technology, based on MapInfo 9.5 and ArcGIS 9.2 packages was used for the building of the information and cartographic database. Original thematic maps compiled on the basis of the research results\' analysis have been obtained in this research. The features of the Caspian Basin\'s karst landscapes, formed as a result of salt-dome tectonic manifestations (Inder Mountains, Malaya Bogdo Mountain, Bish-Chokho hill) are described in this paper. The important elements of the Caspian Basin salt-dome landscapes are landforms of the karst origin from large karst depressions of the karst-tectonic origin to modern forms of the sulfate karst: sinkholes, wells, polje, knobs (\"Kurgantau\"), arches, caves and grottoes. Some karst formations have a non-salt-dome origin. Three areas with the collapsed forms that have the karst-suffosion origin have been identified (near Konyr village, Berezovka village and Zhanatalap village). The mechanism of these sinkholes formation is due to the changes of the groundwater regime and the displacement of limestone eluvium as a result of active anthropogenic impacts. The sinkholes occurrence near Zhanatalap village, which is located near the Karachaganak oil and gas field, is probably due to the anthropogenic initiation of karst-suffosion processes.

Реферат: Current trends of construction industry development by the criterion of rational environmental management deman scientific approach on further ensuring production of construction materials with available raw material resources, decrease in labor costs and energy recources. For the purpose of decrease in roasting temperature, sensitivity coefficient to drying for energy consumption when drying, and also inereases of strength indicators, the influence of bentonite clay for obtaining front wall ceramics was investigated. Rational structures of ceramic composition of ceramic brick by the method of semidry pressing with the use of low-grade loam and bentonite clay were received as a result, influence of temperature of roasting on change of physicomechanical properties of the samples on the basis of the develored structures of composition was investigated, consistent patterns of structure and phase formation of ceramic composition depending on roasting temperature were determined. At the research of physicomechanical properties of the obtained samples, it was revealed that mix modifying by bentonite clay previously activated to nanodimensional particles, led to the inerease in crack resistance of ceramic mass, durability inerease for 30-40 % at the general decrease in temperature of roasting for 100-150 C.
