The article considers the topographic location, chronology, economy and excavations of the medieval site of Koskuduk, located in the Shui Valley. Although the first information about this site entered scientific circulation in the late 1980-th, accurate and scale excavations were not carried out. The Shui archaeological detachment (head Y.Sh. Akymbek) of the Institute of Archaeology named after A.Kh. Margulan in 2018 in the eastern corner of the medieval site of Koskuduk was organized the test pit, shurf and in 2019 on the site of the North-Eastern gate excavates and receives valuable information about the periodization, fortification, the economy of medieval city. The authors of the article draw the special attention to the etymology of the names of the gates in general, medieval gate structures in the Shui Valley, based on researched of other city gates. The radiocarbon analysis of charcoal from pit was carried out in 2018, and it was established that the site dates back to the XI-XII centuries (1043-1104 (41.1%) calAD; 1117-1211(54.3%) calAD). The ceramics complex, discovered at the gate site, is dominated by tableware. The X-ray diffractometric analysis of one instance of kitchen and dining utensils was carried out in order to determine which minerals are contained in the clay of the detected ceramic products. As the result, although the minerals and other impurities in the clay composition of the dishes are generally the same, there are significant differences in percentages. There are number of whole buried skeletons of dogs and partially entire preserved skeletons of horses were found at the gate zone. In addition, archaeozoological analysis of other osteological materials identified in the excavations was carried out, as well as comparative studies of the external forms of pets (cattle and dogs).

Xenophyophores are a group of giant deep sea protists characterized by intracellular barium sulphate (BaSO4) crystals. X-ray diffraction, electron diffraction and electron microscopy studies have been performed on barium sulphate crystals from three xenophyophore species (Aschemonella ramuliformis, Reticulammina labyrinthica, Galatheammina lamina) obtained at bathyal and abyssal depths in the north-eastern Atlantic. Two populations of crystals were observed. The first were tablets, ~2μm in length and rhombic or hexagonal in outline. In both cases, the tabular face was of index (100). The second population consisted of much smaller particles (<0·5 μm) of poor crystallinity. A comparison of the larger xenophyophore crystals with synthetically grown crystals indicated that the former probably grew at low supersaturation (S<25) in solutions of low to moderate ionic strength (I<l·0 M). Some preliminary observations of the cellular organisation of A. ramuliformis are reported. The protoplasm is multinucleate and characterized by what seems to be a system of extracellular lacunae formed by imaginations of the cell wall. Similar features have been observed in the deep sea foraminiferan Rhizammina algaeformis. Possible origins of the BaSO4 crystals and the taxonomic relationship between xenophyophores and certain foraminiferans are discussed.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

Income is an important indicator for assessing the level of economy development as well as identifying and assessing living standards. The population in Northeast border is poor, facilities are outdated, people’s life is difficult, but it hold great potentials for economic development. However, the region’s biggest challenge today is low living standards and high poverty rate. Differences in income and living standards across regions and strata tend to increase the gap. The sustainability of the trend of income increase and improvement of living standards of the population is not stable. As a result, the development of mountainous areas is dependent on poverty reduction solutions for ethnic minorities through the increase of incomes and improvement of market connectivity for ethnic minorities in mountainous areas.
