Quaternary time scales for the Pontocaspian domain: interbasinal connectivity and faunal evolution

The Pontocaspian (Black Sea - Caspian Sea) region has a very dynamic history of basin development and biotic evolution. The region is the remnant of a once vast Paratethys Sea. It contains some of the best Eurasian geological records of tectonic, climatic and paleoenvironmental change. The Pliocene-Quaternary co-evolution of the Black Sea-Caspian Sea is dominated by major changes in water (lake and sea) levels resulting in a pulsating system of connected and isolated basins. Understanding the history of the region, including the drivers of lake level and faunal evolution, is hampered by indistinct stratigraphic nomenclature and contradicting time constraints for regional sedimentary successions. In this paper we review and update the late Pliocene to Quaternary stratigraphic framework of the Pontocaspian domain, focusing on the Black Sea Basin, Caspian Basin, Marmara Sea and the terrestrial environments surrounding these large, mostly endorheic lake-sea systems

Return migration issues in Kazakh-Chinese relations: Mobility and immobility in migration of Kazakh diaspora in China

In the paper the Kazakhstan migration research is carried out, its role in social and economic life of Republic is defined, main stages are established. Recommendations on improving Migration policy of the Republic of Kazakhstan are proposed. As a result of the research, it was revealed that the current Law on Migration of the Republic of Kazakhstan may not positively stimulate the process of resettlement of ethnic Kazakhs from China. It is recommended to work directly with Kazakh youth abroad in order to give a new impetus to the process of migration of the Kazakh diaspora to Kazakhstan

SPECTROPHOTOMETRÄ°C STUDY OF THE COMPLEX FORMATÄ°ON OF COPPER (II) WÄ°TH 1-PHENYL-2- [2-HYDROXY-3-SULFO-5-NÄ°TROPHENYLAZO] 1,3-BUTADÄ°ONE Ä°N THE PRESENCE OF CATÄ°ONÄ°C SURFACTANTS.

Based on benzoylacetone synthesized 1-phenyl-2- [2-hydroxy-3-sulfo-5-nitrophenylazo] 1,3-butadione (PHSNPAB). Studied complex formation of copper (II) with 1-phenyl-2- [2-hydroxy-3-sulfo-5-nitrophenylazo] 1,3-butadione (PHSNPAB) in the presence and absence of the third component such as cetylpyridinium chloride (CPCl), cetylpyridinium bromide (CPBr) and cetyltrimethylammonium bromide (CTMABr). Single ligand complexes are formed at pH = 3, λ = 444nm, and mixed ligand complexes at pH = 2 λ = 456, 454, and 461 nm, respectively (CPCl, and CPBr, CTMABr). İdentified the relations of the reacting components in homogeneous composition of Cu-R (1: 2) and mixed ligand Cu-R-CPCl (1: 2: 2), Cu-R-CPBr (1: 2: 2) and Cu-R-CTMABr (1 2: 1) complexes, which concentration interval subordinated to Beer's law. The influence of external ions and masking substances on complex formation was studied. Method for the photometric determination of copper in the rocks was established

The Salts of Nitronic acid as CO2-Corrosion Inhibitors

The salts of nitronic acids were obtained by nitration of higher olefins, both normal and isomeric structure in the presence of aqueous alkali. The resulting salts (Na+, K+, NH4+), were tested in CO2 -media as a corrosion inhibitor. The results showed that, the protective effect of the linear nitronated olefins increases by increasing the number of carbon atoms. This is due to the fact that because of  the branched structure of the compounds, it is much more difficult to form a dense protective layer on the metal surface. 20% solutions of nitronated ethanolamine in isopropyl alcohol was synthesized and tested as corrosion inhibitor in carbon dioxide environments. The results showed that diethanolamine nitron based on a mixture of normal olefins C16-C18 at a concentration of 50 ppm has a high protective effect of  99.69%

Raise of short-stemmed vaviloid branched spike lines and their cytogenetics

Hybridization between hexaploid species of wheat (Triticum L.) and triticale (Ч Triticosecale Wittm.) is used widely in genetic research and breeding when studying mutual introgressions of genetic material to original species. As far as the hexaploid triticale obtained in our Institute possessed a strong potential of morphogenesis, we decided to use it in crosses with bread wheat. During the process of morphogenesis in hybrid population of the second and third generations derived from the crosses between hexaploid triticale with different bread wheat cultivars (Opal and Chinese Spring) and variety (Triticum aestivum var. velutinum), plants with wheat, rye, intermediate, and triticale-like spike types were noted. Starting from the third generation, constant short-stemmed vaviloid branched spike plants were isolated among populations under study. Despite instability and numerous meiotic aberrations observed in the first generation of plants, including branched-spike ones, the subsequent progeny demonstrated meiotic and morphological stability. The chromosome composition of one of the lines (378/3SD) was characterized by fluorescence in situ hybridization (FISH) and genome in situ hybridization (GISH), and it was identified as a substitution line. Chromosomal identification of such lines will allow their use in genetic studies concerning specified traits, in particular, the vaviloid branched spike
