Resistance of solonetzic soils to rocket and space activity impact in central Kazakhstan.

Introduction. This paper provides the results of a comparative analysis of physicochemical and biological characteristics of soil cover at the fall places of the first stage of “Proton" Launch vehicle (LV) in the area of Yu-2 (Central Kazakhstan). In particular, we considered the ecological stability of brown solonetzic soils in combination with Solonetz soil, to chemical pollution and variability of soil microflora to mechanical stresses during the fall of the separated parts of space launch vehicles (SLV SP). Materials and Methods. We have chosen those Kazakhstan's territories that are used by the Baikonur Cosmodrome as an impact areas of separating parts of space launch vehicles (SLV SP IA), in June 2017, to conduct ecological studies in those places, where the first-stage vehicles of the Proton rocket have been fallen in the Yu-2 zone (Central Kazakhstan). Here the pollution of UDMH (unsymmetric dimethylhydrazine, rocket fuel, substance of the 1st class of toxic hazard) has been detected in soils in 2000-2007. Control point were also chosen in the adjacent territory. Morphological and physico-chemical properties of soil profiles have been studied. In 10 soil samples, indicators of the state of microflora and phytotoxicity were determined. Results and Conclusions. Based on the results of the analysis of the characteristics of solonetzic soils at the fall places of separated parts of space launch vehicles "Proton" in the Yu-2 zone (Central Kazakhstan), it was concluded that they have high resistance to chemical pollution of UDMH. The processes of physico-chemical transformation of UDMH and its processing by soil microorganisms are assumed in the illuvial B horizons, due to the high content of exchangeable sodium, against the background of sufficient soil moisture with an alkaline pH-medium (up to strongly alkaline). At the same time, low microbiological indices, the absence of spore-forming bacteria, and the presence of plant phytotoxicity were found in soils of the fall places. Microbiological restoration of fertile top soil in technogenic disturbed lands of the Yu-2 zone is extremely difficult in conditions of high soil alkalinity, in the presence of saline clay and increased content of carbonate

Vaginal biotope in women of reproductive age with pelvic floor dysfunction

The article indicated the relevance of pelvic floor dysfunction in women of reproductive age. The dependence of the vaginal biotope and cervical disease from having NTD revealed the earliest pathognomonic sign of of pelvic floor dysfunction

Pathogenes,diagnostics and treatment of chronic endometritis

Chronic endometritis (CE) is a cause of a reproductive loss in 30-35% of the cases (E.B. Johnston-Macannany et al., 2009). 80–90% of patients are women of reproductive age. Today there is no strict algorithm of observing women with CE, including all links of pathogenesis. Latent course, absence of clinical manifestation, lack of self-descriptiveness of routine methods of diagnosis define difficulties of prevention and treatment of CE. Studying possible mechanisms of development of CE, creation of the most effective methods of diagnostics, treatment and rehabilitation of the patients with such a disease are the most urgent problems of modern obstetrics and gynecology

Compliance and its importance in pelvic organ prolapsed

The analysis of recent data on the prevalence and effectiveness of various treatments for pelvic organ prolapse in women justifies the need to study compliance surgical and “conservative” approach in the treatment of this disease

Biotechnology of the Recultivation of Technogenically Disturbed Landscapes in the South and East of Kazakhstan (биотехнология рекультивации техногенно – нарушенных ландшафтов наюге и востоке казахстана)

Reclamation of technogenically disturbed lands requires several procedures and assignments. In the South of Kazakhstan during the field development of phosphate deposits, pastoral type lands were disturbed. Reclamation works were done in two stages - technical and biological. The technical stage included the dump planning, loamy ground delivery for bottom lining, layer-bylayer covering and stabilisation. The biological stage included planting of phyto-meliorants, biochar and carbamide insertion under crops. In the city of Ridder, around the mining processing industry, the black humus soil was exposed to aggressive emission of zinc plant. The soil is currently degraded and devoid of vegetation cover, and undergoing deep erosion processes. Biological reclamation was carried out on this site utilizing biochar and phyto-meliorant

TR-therapy in case of inconsistency of the pelvic floor

The failure of the pelvic floor (NTD) is a common syndrome in the modern female population, in which there is a combined or isolated prolapse of the pelvic floor and pelvic organs. In the study, tissues of the vaginal walls of 20 patients were studied by pelvic floor failure using light microscopy, PCR diagnostics, and immunohistochemistry before and after treatment with contact diathermy method. The results of the study of the material obtained after a course of diathermic treatment indicate compensation of chronic oxidative stress at the molecular level by leveling the imbalance of collagen and elastin and restoring the architectonics of the vaginal wall. © 2019, Advanced Scientific Research.

Soil-forming processes in the phosphorite deposits dumps «Kokdzhon» in Zhambyl region

According to the description of sections on the natural overgrown areas dumping deposit «Kokdzhon» initial signs of soil formation revealed. At the site where it has the character of the natural overgrowth of single plants the process of soil formation is absent or very weakly expressed. The differentiation of dwarf horizons is visible on the profile of all cuts. In the process of soil formation, particle size distribution varies. The upper horizons of the soil profile are enriched with silt particles in the accumulation of clay minerals and humus; when lessivage and other processes is the transfer of sludge or its breakdown products from the upper to the lower horizons. At the study sites the finer fractions increase indicates, that may have accumulated due to water erosion and weathering of surface rock dump. Humus determination of suggests that soilforming processes are affected by the upper layers of soil dump, in the lower horizons of the humus content varies from 0,17 to 0,54 %, which corresponds to the stripping waste dumps. Despite the paucity of plant foods and stiffness of the climatic conditions, the presence of representatives of the micro-and mesofauna in soil on the Kokdzhon deposits gives grounds to assume that the initial process of soil formation in the dumps is grayed out, slowly.По описанию разрезов, заложенных на естественно-зарастающих участках отвала месторождения «Кокджон», были выявлены инициальные признаки почвообразования. На участке, где естественное зарастание имеет характер единичных растений, процесс почвообразования отсутствуют или очень слабо выражен. По профилю всех разрезов заметна дефференциация карликовых горизонтов. В процессе почвообразования гранулометрический состав изменяется. Верхние горизонты почвенного профиля обогащаются илистыми частицами в результате накопления глинистых минералов и гумуса; при лессиваже и других процессах происходит перенос ила или продуктов его распада из верхних горизонтов в нижние. На исследуемых участках отмечается увеличение более тонких фракций, которые, возможно, скапливаются вследствие водных эрозионных процессов и выветривания поверхностных отвальных пород. Определение содержания гумуса свидетельствует, что процессами почвообразования затронуты верхние слои почвогрунтов отвала, в нижних горизонтах содержание гумуса колеблется от 0,17 до 0,54 %, что соответствует вскрышным породным отвалам. Несмотря на скудность растительной пищи и жесткость природно-климатических условий, присутствие представителей микро- и мезофауны в почвогрунтах месторождения «Кокджон» дает основание считать, что начальный процесс почвообразования на отвалах идет неактивно, медленно

On Guaranteeing Global Dependability Properties in Collaborative Business Process Management

Abstract. The Service-Oriented Architecture (SOA) paradigm supports a collaborative business model, where business applications are built from independently developed services, and services and applications build up complex dependencies. Guaranteeing high dependability levels in such complex environment is a key factor for the success of this model. In this chapter we discuss issues concerning the design of such software sys-tems, evidencing the limits of the proposed approaches, and suggesting directions for advancements in this field. Moreover, we also discuss issues concerning the case of self-adaptive SOA systems, whose goal is to self-configure themselves, to cope with changes in the operating conditions and to meet the required dependability with a minimum of resources.
