The ecostratigraphy shows significant patterns of species composition related to the succession of pedocomplexes and loess, respectively. Pedocomplexes included species that can be associated with highgrass- to forest-steppe biomes, indicating increased humidity for these sections compared to loess layers. In contrast, loess layers that relate to glacial periods are associated with gastropod species of semidesert environments with shrub- and shortgrass-steppes, indicating semiarid to arid conditions. Furthermore, the loess deposits do not show any evidence for cold-adapted gastropod species. Therefore we suggest that average July temperatures in the study area were above 10°C, even during periods of loess deposition. We propose, that the limiting factor for bios during glacial periods was aridity, rather than temperature. In addition, we observe environmental differences between the various glacial times, with our results indicating a trend towards steadily increasing aridity in Southern Caucasia across the Middle to Late Pleistocene.</p>

For the first time, a detailed study of the qualitative and quantitative composition of ginsenosides in the Panax ginseng roots was carried out with the help of high-performance liquid chromatography combined with mass spectrometry (HPLC-MS). The plants were introduced into the conditions of the Republic of Belarus at the experimental plot of the Central Botanical Garden of the National Academy of Sciences of Belarus. It was found that in the examined roots, all basic neutral glycosides of ginseng (ginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rf, Rg1 and Re), as well as their malonylated derivatives (malonylginsenosides Rb1, Rc, Rb2/Rb3, Rd, Rg1 and Re) and some “minor” ginsenosides (20-gluco-ginsenoside Rf, notoginsenosides R1 and R2, isomers of malonyl-ginsenosides Rb1 and Rd) are present. The research also showed that different parts of the P. ginseng roots differ significantly in a total content of ginsenosides: for the main root, this parameter was 3.3 % of dry mass, and for the lateral roots – 7.8 % of dry mass.

The article republishes the ceramics and bronze decorations of Komarovo and Sosnitsa cultures of the Trzciniec cultural circle (TCC) from the exposition of the Archaeological Museum of the Institute of Archeology of the National Academy of Sciences of Ukraine. Detailed descriptions of the exhibits and their author’s graphic reconstructions are given. These things, which became a textbook long time ago, previously were published only in the form of schematic and inaccurate drawings or in the form of not very high-quality photographs. The materials originate from the sites of the northern part of the forest-steppe eastern Volhynia (Wojciechowka), Kiev (Ukrainka, Zavalovka, Zdvizhevka, Plitovische, Gostomel) and Chernigov (Rudnya) Polesie. The finds refer to different periods of the formation and development of the TСC and date back to 2nd thousand BC. Special attention is paid to vessels discovered in 1956 by N. T. Evstropov at the site Gostomel, Stekol’nyy zavod 1. S. S. Berezanskaya came to the conclusion that this point is not a household site, but «a small soil burial ground with burning», referring to a series of observations of N. T. Evstropova. Detailed comparison of the primary publication of N. T. Evstropov with subsequent re-publication of the site of S. S. Berezanskaya, allow us to call into question conclusions of the latter. One of the reasons for skepticism is the miraculous transformation of «destroyed teeth of a ruminant animal» (in N. T. Evstropov publication) into «worn-out» and «calcified bones» (in S. S. Berezanskaya publications). Fragments of the teeth of a ruminant animal (bull?) are still folded into one of the vessels exhibited at the Archaeological Museum of Institute of Archeology of the National Academy of Sciences of Ukraine. Could the vessels from Gostomel be connected with ritual-funeral practice, such as the vessels found in the ritual-funeral complexes of the Malopolovetskoe, Wojciechowka, Bukovna cemeteries? It is possible, but there is no evidence for this. Similarly, they can be associated with any other rituals, as well as with the remains of an ordinary household complex. N. T. Evstropov did it at the first publication of the site. Analysis of the ceramic complex allows us to attribute the Gostomel, Stekol’nyy zavod 1 point to the turn of the middle and late stages of the TCC Sosnitsa culture and date it to the end of the 13th — the beginning of the 12th centuries BC.

. Many important issues and problems related to the future of the nation are raised and analyzed primarily by representatives of the intellectuals, including those in university classrooms. L. N. Gumilyov Eurasian National University is one of the largest universities in Kazakhstan. The university celebrates its 25th anniversary this year. The Department of Philosophy is involved in the celebration process as well. Philosophy is of great importance for the culture of thinking of modern mankind, the formation of a critical attitude towards the social face of the country, contributing to the expansion of the spiritual outlook of students and the development of national consciousness, the spiritual revival of the nation. Philosophy, which is one of the leading disciplines in the social sciences and the humanities studied in higher and professional schools, from the first days of our university through the staff of the chair has contributed to the development of young students. At the Philosophy Chair of the Faculty of Social Sciences work three academicians of the National Academy of Sciences of the Republic of Kazakhstan - Abdildin J.M., Garifolla Esim, Nurmanbetova D.N. In addition, about two dozen of doctors and candidates of sciences work at the chair, which shows the high potential and professional skills of the staff. Currently, the Department of Philosophy is headed by Doctor of Philosophy, Professor Kulshat Agibaevna Medeuova. This article will talk about the work of the teaching staff of the Department of Philosophy and about new beginnings and the importance of the activities of academician, thinker, writer, teacher and public figure, Doctor of Philosophy, academician of the National Academy of Sciences of Kazakhstan Garifolla Yesim. Since 2013, the Philosophy Department has been successfully working on a new system of research, creative, methodological work, the foundations of which were laid by Academician Garifollah Yesim. It should be said that Garifollah Yesim from the moment of his arrival at the chair of philosophy after working in the Senate was able to structure and systematize his creative search and ideas, which he pondered all his life, developed a philosophical concept «Zhaksy Kazak», directly related to the national idea «Mangilik El». This concept presents the essence of the category «Zhaksy-Kazak» considered from the image position and seven stages of its achievement. It should be said that these seven stages are worked out in the educational and methodological plan and are studied in the educational programs «Philosophy», «Culture Studies» as elective disciplines.
