Golden horde sites at the Aral Sea bottom: human adaptation to ecological changes in the region
No full textThe research described in the paper aimed to investigate the Golden Horde sites in the Aral Sea Basin and human adaptation to the region’s changing ecology. At present, several known settlements at the drained Aral Sea bottom – namely, Kerderi-1, Kerderi-2, and Aral-Asar – testify to the lake’s shallowness during XII-XV centuries. In August 2021, a group of archaeologists from Korkyt-Ata Kyzylorda University conducted a research mission to the location of the former settlement of Aral-Asar as part of the ESERA Project. The results of the study show that Aral-Asar existed for approx. 200 years as a full-fledged economic entity hosting cereal, ceramics and brick productions. In general, the data obtained indicate that environmental changes had led to the desolation of certain cities and development of new lands by humans in the Syr Darya River Delta, including these found at the drained bottom of the Aral Sea
Water management issues of Aral Sea
No full textIn the introducion of this seminar paper author deals with former natural conditions of Aral lake. It focuses on climatic conditions, morphology, hydrology and local land use situation.Because the region of Central Asia has been historically wedged between the three empires, it is also appropriate to describe closer the historical and political development of the region. The focus of the thesis is to analyze the causes of hydrological changes, when the desertification of Aral Lake has a catastrophic impact on the ecosystem and human society in the region. The return of Aral Lake to the situation sixty years ago is, unfortunately, unrealistic, but various remedial measures are being implemented to improve the situation as much as possible. The goal is to make the most of the situation. This is also done through various international projects. Therefore, the vision of the future development of the region around Aral Lake is outlined. There are also similar cases in the world, most notably the Dead Sea. The work concluded that at least some hope for recovery unfortunately only has the northern part of Aral's lake, while the southern part is probably lost forever

Although the procedure of indirect determination of reference intervals using stored data is not defined in any guide, it was showed that the reference intervals could be estimated by indirect method in lots of studies. We aimed to constitute a model of using stored data in verifying the reference intervals of prothrombin time (PT) and activated partial thromboplastin time (APTT) with exclusion of certain clinics in this study. Materials and Methods: Results of PT (N11,363) and APTT (N7,034) test requests of ambulatory patients aged 15 to 80 made from outpatient clinics of surgical departments before surgical interventions in 2008 were retrieved from the electronic medical record. Certain clinics were excluded. Thromborel S and Actin (Dade Behring, Germany) were used for the tests which we done on the Sysmex CA-1500. We used Bhattacharya and Hoffmann methods as a retrospective quality control procedure for each study week. When we compared the sensivities of these methods, the results were similar. Results: We determined the weeks where there was disagreement between the results of internal quality control and patients tests and excluded the results of these weeks in estimation. When we compared the sensivities of these methods (Bhattacharya and Hoffmann), the results were similar.The indirect reference intervals estimated by using the stored data with the exclusion of certain clinics and the retrospective evaluation of the internal quality conrol results were overlapping with the data stated in the insert. Conclusion: The model which we constituted using stored data, may be particularly suitable for confirming reference intervals of the laboratory and evaluation of the results of the presenting population

Pozornost je proto věnována klimatickým poměrům, morfologii, hydrogeologii i využití tamní krajiny. Protože oblast střední Asie byla historicky zaklíněna mezi tři říše, je na místě přiblížit i historicko-politický vývoj regionu. Těžiště práce pak spočívá v analýze příčin hydrologických změn, kdy má vysychání Aralského jezera katastrofický dopad na ekosystém i lidskou společnost v regionu. Návrat stavu Aralského jezera do situace před šedesáti lety je bohužel nereálný, ale přesto jsou uskutečňována různá nápravná opatření, která mají za cíl situaci v rámci možností co nejvíce zlepšit. Děje se tak i prostřednictvím různých mezinárodních projektů. Nastíněna je tudíž i vize budoucího vývoje regionu v okolí Aralského jezera. Ve světě existují i analogické případy, z nichž asi nejznámější je Mrtvé moře. Práce dochází k závěru, že alespoň trochu reálnou naději na záchranu má bohužel jen severní část Aralského jezera, kdežto pro jižní část je nejspíše navždy ztracena.Ústav hydrogeologie, inž. geologie a užité geofyzikyInstitute of Hydrogeology, Engineering Geology and Applied GeophysicsPřírodovědecká fakultaFaculty of Scienc
Natural and anthropogenic rapid changes in the Kara-Bogaz Gol over the last two centuries reconstructed from palynological analyses and a comparison to instrumental records
No full textPalynological analyses (pollen and dinocysts) of a sediment core taken in the Kara-Bogaz Gol have been used to
reconstruct rapid and catastrophic environmental changes over the last two centuries (chronology based on 210Pb). A
natural cyclicity (65 years) of water level changes in the Caspian Sea and in the Kara-Bogaz Gol and anthropogenic
factors (building of a dam separating the CS and the KBG waters) combine to induce rapid changes in water levels of
the KBG, in the salinity of its waters and in vegetation cover of its surroundings. The impact of low water levels on
the dinocysts is marked by a lower diversity and the survival of two species that are typical of the KBG, the Caspian
Sea species present in the KBG having disappeared. During periods of higher water levels (AD 1871 to 1878), the
lake is surrounded by a steppe-like vegetation dominated by Artemisia; whereas during periods of low water levels
(AD 1878 to 1913 and AD 1955-1998), the emerged shore are colonised by Chenopodiaceae. The period of AD 1913
to 1955 corresponding to decreasing water levels has an extremely low pollen concentration and a maximum of
reworking of arboreal taxa. During the last low-level period, humans responded by abandoning the shores of the bay.
What happened to the KBG can be used as an example of what may happen in the future for the Aral Sea.
A problem of reworking of Tertiary dinocysts into modern deposits has been detected owing to the knowledge of the
modern dinoflagellate assemblages recently made available through a water survey. A comparison to modern surface
pollen samples from Central Asia (Anzali, Caspian Sea south and central basins, Aral Sea, Lake Balkhash, Lake
Issyk-Kul and the Chinese Tien-Shan range) allows us to establish the potential reworking of at least five arboreal
pollen taxa possibly by run-off and dust storms
SCIENTIFIC STUDY OF THE ARAL SEA AND ITS COASTLINE BETWEEN 1848-1849
No full textThe article deals with the scientific study of the Aral Sea, which began in the mid-XIX-th century during the strengthening of the Russian Empire in the Central Asian region. Based on archival materials and scientific articles, the course and results of expeditions conducted by A.I. Butakov are described. The article reveals the details of the study of the Aral Sea, as well as the coast of the Aral Sea in 1848-1849. The author pays much attention to the discovery of new islands in the Aral Sea, as well as the process of scientific observations and surveys made from the sea. It is shown that the Aral Sea and its coast remained unstudied for a long time because of its remoteness and inaccessibility
armagan aral dissociation dataset
No full textThis is raw and analysis data for empirical study, entitled 'Dissociation and Trauma Impact Non-suicidal Self-injury in Adolescents'.The main objective of this study was to explore the role of dissociation and social problem solving in Non-Suicidal Self-Injury (NSSI). Secondary aims were to demonstrate possible variables related to NSSI functions and test whether dissociation is a mediator of the pathway from trauma to NSSI. The sample consisted of 90 adolescents, aged 12-18 years, and 90 age and sex-matched control subjects. Hierarchical logistic regression analysis was performed to predict the occurrence and recurrence of NSSI. The findings showed that depersonalization (OR=3.91 and OR= 12.13, respectively) and depression severity (OR=1.05 and OR=1.22 respectively) were independent predictors of the occurrence and recurrence of NSSI. Depersonalization (b=.0129) accounted for significant mediation in the relationship between trauma severity and NSSI recurrence
Defining absolute environmental limits for the built environment
No full textThe question addressed is whether it is possible to define working limits on environmental impacts from the built environment in terms of global carrying capacity. The main focus is on energy-related impacts, since these are global and relatively well-understood. Four possible approaches to defining limits are explored: static equilibrium, asymptotic, integral of excess and planned future. The conclusions that emerge from this exploration are that global environmental constraints are very tight, but also that they are dynamically and strongly influenced by the trajectory of social and technological development over the coming century. Their use as the basis for practical, quantitative metrics of sustainability, therefore, involves a large measure of subjectivity. A fifth approach - the developmental approach - is identified, which instead of focusing on long-term external constraints to human activity, focuses instead on the internal, short- to medium-term dynamics of the built environment itself. It appears likely that the developmental approach, guided by qualitative conclusions from the analysis of global carrying capacity, is likely to be most fruitful

Present state of the Aral Sea: diverging physical and biological characteristics of the residual basins
No full textLatest data on the hydrophysical and biological state of the residual basins of the Aral Sea are presented and compared. Direct, quasi-simultaneous observations were carried out in the central part of the Western Large Aral Sea, the northern extremity of the Large Aral known as Chernyshev Bay, Lake Tshchebas, and the Small Aral Sea in October 2014. The Large Aral Sea and Lake Tshchebas transformed into hyperhaline water bodies with highly special taxocene structure. The Small Aral Sea was a relatively diverse brackish ecosystem, which was rather similar to the pre-desiccation environment. The Small Aral Sea and Lake Tshchebas exhibited a fully-mixed vertical structure, whereas the Western Large Aral Sea was strongly stratified. Our data show that during desiccation, different parts of the Aral Sea experienced different environmental conditions, resulting in qualitative and quantitative differences in the physical and biological regimes among the different residual basins
