Reservoir Basin

On the north-eastern slope of the Lesser Caucasus, within the boundaries of Shamkir administrative district, the most common soils in the Shamkirchay reservoir basin are gray-brown (chestnut) soils. Since the commissioning of the reservoir, these lands have been intensively used as new irrigated areas under agricultural production. To some extent, non-compliance with planting norms when using irrigation can lead to a decrease in soil fertility parameters, soil degradation, and an increased risk of salinization. The main purpose of the study is to analyze the current state of the main physicochemical and fertility indicators of soils in the basin and the relationship between them in the gray-brown (chestnut) soils spread within the basin boundaries of the reservoir. Diagnostic indicators, agrochemical properties and results of their analysis of soil plots placed in characteristic places were analyzed in tables and explanations. The main indicators are humus, total nitrogen, phosphorus and potassium, granulometric composition (sand, dust, silt and clay fractions), soil environmental reaction (pH) and carbonate content (CaCO3), statistical analysis. The article has covered studies in dark, conventional and light gray-brown (semi-brown) semi-soils in three sub-areas of gray-brown (chestnut) soils, mainly distributed in the Shamkirchay reservoir. In each of the three subclasses, profiles are set in specific locations. The practical part has been implemented in 2 stages. During the field studies, 9 profiles have been excavated, relevant samples have been taken, and analysis has been performed to determine the diagnostic performance. The results of the analyses have been presented in the respective tables and have been analyzed in detail. All analyses have been carried out on the basis of modern methods.

The article is devoted to the development of a plan for distribution of surface water resources for river basins of the North-Eastern slope of the Lesser Caucasus within Azerbaijan in compliance with the requirements of the EU Water Framework Directive. This is, in fact, the first such plan for the country’s river basins. Its main components are consisted of existing surface water resources, the quantity of environmental flow, water use indicators for drinking water supply and irrigation. Some of these components have been determined based on the data over the recent years, while others have been calculated using specific methods or estimated indirectly. The volume of environmental flow, as one of the priority components of the plan, had been determined in two different ways. Given that the water resources of the studied region are limited, the amount of environmental runoff was taken at 20% of the long-term annual runoff in water distribution plan. The main water user in the region is agriculture. Eleven water reservoirs have been built with the aim to achieve rational use of river runoff. Water losses in the irrigation systems of the region are at least 21%. The plan is designed both for the modern period and for 2035. It is shown that the water management balances of the studied river basins are characterized positively. However, if the extremely dry period of 2014–2020 is going to continue, the situation may worsen. A number of gaps were identified in the process of compiling the plan that affect the accuracy of evaluation of individual components. These gaps concern technical, legislative and institutional issues. It was noted that the approach used in this study could be used in other river basins of the country. It is also necessary to include groundwater resources and their use in water allocation plan.

On the highlands of the north – eastern part of the Lesser Caucasus were investigated ontogenetic characteristics Cerastium davuricum in different type of plants. There are found that cenopopulation spices goes through a 4- and 10-year periods. Age composition cenopopulations species is very variable and is associated with the biological characteristics of species composition of the sward, the economic use of pastures. In research found the following types of cenopopulation: normal, invasive, regressive. Meanwhile, the predominance of vegetative individuals in the population in the first case indicates the weakness of cenopopulation, and in the second case, the high number of generative individuals indicates the sustainability of cenopopulation. This arrangement of population under less favorable conditions compared with another one.

The rivers flowing from the north-eastern slope of the Greater Caucasus are among the rivers that flow directly into the Caspian Sea. Sludge, sand, various suspended solids, organic compounds, mineral salts, etc. in river water. both naturally and through irrigation. As a result of multi-year irrigation, agro-irrigation horizons of different thicknesses are formed by the accumulation in the soil of water-derived organic and mineral compounds. Significant changes in the mechanical composition of the soil occur due to the accumulation of materials here. First of all, the amount of small fractional physical activity increases, geophysical and geochemical processes change. The density of the soil increases, the reclamation condition deteriorates, the drainage capacity weakens, and the air and water regime are negatively affected. During the research, the hydrological features of the area rivers, feeding regime, areas irrigated by the rivers, ecological analysis of the river and canal waters and the complex of physical-geographical factors causing it were studied. Key words:water supply, water consumption, irrigated areas, canal water, ecological analysis of river water, physical-geographical factors

Background: Numerous studies have documented the association of the ABO blood groups with the occurrence of cancers. Aim was to find out an association of ABO blood groups and various cancers in the North Eastern region of India.Methods: The study was a retrospective observational study that included 1000 cases and 1000 controls. The data included the ABO blood typing of the selected cancer sites which were head and neck, esophagus, stomach, breast, cervix, and ovary. Patients who attended blood bank of regional cancer center with requisition for blood transfusion from 2014 to 2016 were included. The control group was healthy blood donors. Chi square test was used to assess the difference among the compared groups. Risk was calculated by regression analysis. P value <0.05 was considered as statistically significant at 95% confidence interval.Results: Out of 1000 cases and 1000 controls, O blood group were seen in 377 (37.7%) and 395 (39.5%) cases and control, respectively. Significant reduced odds ratio (OR) in non O blood groups for head and neck, esophagus, stomach, and breast was observed. In case of carcinoma cervix, OR for B group was 1.5 (P=0.05), and for blood group A OR=2.2 (P=0.02) was seen in carcinoma ovary.Conclusions: In the studied population, patients with O blood group are at an increased risk of developing head and neck, esophagus, stomach, and breast cancers.

The article presents materials from the excavation work of the mound 1 from the Egorlyk group. The mound was formed over two burials of the Yamnaya culture of the early Bronze Age era. The only inlet burial was placed in the center of the mound during the transition period from the late Bronze Age to the early Iron Age. The discovery of this monument is significant because it is the first monument of the Bronze Age explored on the north-eastern slope of the Stavropol height, in-between the rivers Egorlyk and Kalaus and bounded from the east by the lake Manych.

The article describes the physical-geographical position, geomorphological, geological, climate and hydrological conditions of the North-Eastern slope of the Great Caucasus. The morphogenetic picture of the typical mountain-forest brown, residual calcareous mountain-forest brown, and mountain grey-brown soil profiles is given. The morphogenetic description of the soil resource horizons in the soil profile was performed according to the WRB system. The modern state of agricultural land was comparatively analyzed by examining principal diagnostic indices. The study was confined to Gusar District of the Republic of Azerbaijan. The geographical coordinates of each soil section were determined. The soil formation conditionswere characterized depending on vegetation cover, soil forming rock, slope exposition, and hypsometric level. The soils have been comparatively assessed by humus quality (main indicator of soil fertility), total nitrogen content, pH, calcareous quantity, granulometric composition, and base exchange capacity.
