В статье изложены литературные данные о классификации, этиологии, патогенезе и распространенности аутизма в мире и в Республике Казахстане (РК). За последние годы резко возросла проблема здоровья детского населения, проявляющиеся нарушениями морфофункционального и психофизиологического состояния детей, факт которого связывают с возрастанием экологического и социального неблагополучия. Во всем мире отмечается увеличение заболевания расстройств аутистического спектра (РАС). Аутизм является одним из самых распространенных детских психических расстройств. В последнее время проблема аутизма привлекает к себе внимание, в виду того, что стала распространяться информация об этой проблеме в широких слоях населения, и родители, чьи дети имеют аутизм, стали обращаться к специалистам, что позволяет изучать эту проблему в РК. В статье даны классификация аутизма, основные симптомы характерные для него, показатели учета заболеваемости с 2011 года, которые демонстрируют увеличение количества детей с аутизмом. 2018-01-01T00:00:00Z http://repository.enu.kz/handle/enu/746 The primary school kids’ morphological status of Pavlodar city Tasbulatova, G.S.; Mukataeva, Zh.M. More attention is paid to the study of the peculiarities of physiological processes occurring in the growing body, since the formation and protection of the health of children, adolescents is the main task of any state. The purpose of this research is to study the features of the morphological development of children of primary school age in Pavlodar city. The study of anthropometric parameters of schoolchildren (boys and girls) 9-11 years of Pavlodar was conducted. Studied were such variables as body length (BL), body mass (BM), circumference of the chest (CC), calculated the Quetelet index (QI) and stenia index (SI). Within the scope of research, differences in physical development between boys and girls were revealed. For example, in terms of length, body weight, boys are superior to girls aged 9-10 years, while at 11 years of age girls are more important in these parameters, which is explained by earlier entry into the puberty period compared to peers. According to such indicators as the Quetelet and stenia index, significant sexual differences were observed only at the age of 9. Thus, the study of the physical development of boys and girls 9-11 years showed an increase in the ontogenesis of anthropometric indicators. An increase in the Quetelet index in the compared age of both sexes was revealed, which characterizes the growth processes. Stenia index in ontogenesis decreased in both sexes. 2018-01-01T00:00:00Z http://repository.enu.kz/handle/enu/745 The History of Donyztau flora and vegetation research Kuanbai, Zh.I.; Admanova, G.B. The investigation of the modern content of vegetation is impossible without the analysis of the history of vegetational cover study. The article reveals the historical aspect of Donyztau vegetational cover study and also scans the literature containing the information on the vegetation and plant life of Donyztau, provides the analysis of the region"s vegetation species described by different authors. Donyztau is located on the territory of Baiganinski raiyon of Aktubinskaya oblast. Donyztau chink is regarded as a part of Usturt"s northern part and refers to floristic region 13. Northern Usturt. The Donyztau plant life was being studied by a great deal of scientists but many of them studied more immense areas of Usturt. As far as Donyztau separately taken there was no special floristic research of the territory. Floristically Donyztau still refers to little studied areas of the Republic. During the long period the regional plant life was not the subject for special research. The present materials may serve as basis for the further study of the said district"s plant life. 2018-01-01T00:00:00Z http://repository.enu.kz/handle/enu/744 The emulsifying activity of several hydrocarbon-degrading microorganisms Bekturova, A.Zh.; Sagyndykov, U.Z.; Masalimov, Zh.K. It is known that biosurfactants are capable of increasing the bioavailability of hydrocarbons in oil and petroleum products, as well as modifying the external surfaces of bacteria by hydrophobizing providing direct contact with hydrocarbon molecules. In this study the index of emulsification index was studied for four hydrocarbon-degrading strains of microorganisms such as Achromobacter xylosoxidans, Bacillus subtillus, Tessaracoccus flavescens, Acinetobacter calcoaceticus. Diesel fuel and hexadecane were used as hydrophobic substrates. It is shown that for all members of natural hydrocarbon-degrading microorganisms are characterized by high rates of emulsification index. The highest index of emulsificationis has shown for Acinetobacter calcoaceticus - 80-87%. Microorganisms having an emulsification index bigger than 50% are considered promising producers of surfactants. Since the microbial cell oxidizes hydrocarbons by adsorbing on their surface, as a result, the oil-oxidizing activity of the crops depends on its ability to utilize the hydrocarbon substrate. This could indicate adestructive activity of microorganisms. 2018-01-01T00:00:00Z
