The Zayamchay basin is selected by its complex structure, various climatic conditions, rich vegetation and soil–rich rocks. This variation of soil–forming factors has led to the formation of various forms of soil cover structure within the basin. Therefore, the study of land and its space manifestation — the soil cover structure, detail mapping, evaluation and optimization — both scientifically–theoretical and practical. The Zeyamchay basin, which is located on the north–western slope of the Lesser Caucasus, is the object of the research. The Zeyamchay basin is selected by its complex relief structure, various climatic conditions, rich vegetation and soil–rich rocks. The area of the basin is 94200 hectares. The basin covers part of Tovuz, Shamkir and Gadabay districts from the administrative point of view. These kind of soil–forming factors have led to the formation of different forms of soil cover structure within the basin. During the research, empirical information is collected from cartographic, soil research, aerospace, landscape and geomorphological methods and so on was used.

With the emphasis of the Oxford History of the Ancient Near East firmly placed on the political, social, and cultural histories of the states and communities shaping Egypt and Western Asia (including the Levant, Anatolia, Mesopotamia, and Iran), this introduction to the five-volume series seeks to place the region in its environmental context. It discusses the lay of the land between the North African coast and the Hindu Kush, including the role of tectonics and geomorphology. It also considers some key issues regarding climatic conditions, focusing in particular on the significance of the Inter-Tropical Convergence Zone and the potential impact of megadroughts and pandemics.

The aim of the research is identifying the role of the futurological theories of the XX century in the mod-ern design of modular structures in the water environment. The leading research approach is based on the analysis of the principles of habitat organization from the point of view of the main visionary concepts of the XX century, which developed the idea of life on the water in the future, such as: architectural "metabolism", "mobile" architecture, arсology, architectural biomimetics and bionics. The approaches outlined in the framework of the futurological concepts of the last century include modularity, interchangeability of struc-tural elements, adaptation to changes in climatic conditions, application of the principles of growth and ag-gregation in natural systems to the architecture. The revealed approaches have been elaborated in the contemporary architectural concepts devoted to the development of the extreme water environment. Based on the analysis of implemented and conceptual pro-jects of the floating structures on the water, the types of spatial organization of modules are identified: line-ar, continuous, multiple, arbitrary, centralized. A graphical diagram illustrating the mechanism of aggrega-tion of modules for each type is made. These typologies can be applied in further design and experimental developments and theoretical studies in the field of biosphere-compatible architecture in the context of the aquatic environment.

AbstractFormer studies proposed that the speciation of the subgenus Paraphlebotomus happened in the Neogene Epoch in the circum-Mediterranean region due to the geographical segregation effect of the former Paratethys Sea. It was aimed to study whether the modelled Neogene ranges of Phlebotomus sergenti and Phlebotomus similis support or contradict this barrier role of the Paratethys in the speciation of Paraphlebotomus sandfly. For this purpose, the potential Neogene geographical ranges of Phlebotomus sergenti and Phlebotomus similis were modelled based on the present climatic requirements of the taxa. The Miocene models do not support the circum-Paratethyan migration of the ancestor of Phlebotomus similis. In general, Phlebotomus similis shows a low affinity to the North Paratethyan shorelines during the entire Miocene epoch. The only exceptions are the Tortonian and early Messinian periods when the climatic conditions could be suitable for Phlebotomus similis in the North Paratethyan shorelines. It was found that neither the modelled late Miocene, Pliocene nor the mid-Pleistocene period distributions of Phlebotomus sergenti and Phlebotomus similis shows notable differences in the suitability values in the Balkans and the Middle East. It is most plausible that the divergence of the Phlebotomus similis and its relatives was related to the tectonic subsidence of the Hellene Orogenic Belt and Phlebotomus similis specialised in the Balkan Peninsula and the present-day North Pontic area during the middle-late Miocene epoch. The Messinian desiccations of the Mediterranean Basin and the Zanclean re-flood caused the migration, but not the speciation of Phlebotomus similis and its sister taxa.

The article discusses the results of a four-year study (2016-2019) of breeding lines of spring soft wheat of the selection of Federal Agricultural Research Center of the North-East named N.V. Rudnitsky in the soil and climatic conditions of the central and southern parts of the Volga-Vyatka region. The promising lines C-65, C-103, H-154 were selected as they exceeded the regionalized standard variety Simbirtsit in average yields (3.41...3.56 t/ha; the increase is 0.04...0.19 t/ha), and in terms of potential yield (5.61…6.93 t / ha; the increase is 0.48...1.80 t/ha). According to the long-term average indicators of the crop structure, the selection lines П-57, P-63, С-65 and С-103 were attributed to the sources of valuable properties. Genotypes P-63, H-154 showed higher values and stability of gluten formation in grain relative to the variety Simbirtsit (22.8-24.1%; the increase to the standard is 3.1 - 4.4%). Using the variation coefficient, the degree of variability of economically useful traits (productive bushiness, plant height, ear length, number of grains per ear, grain weight per ear, 1000 grain mass, yield, gluten content in grain) was determined in different ecological environments. It has been established that the variability values of individual characteristics of productivity in one variety are not always consistent with each other and have genotypic conditionality. Yield stability can be closely related to the level of variation of individual elements of its structure. Genotypes that were more stable in yield indicated high variability of productive bushiness and low variability of plant height, grain weight per spike, and mass of 1000 grains. It has been shown that from practical point of view the most valuable genotypes were the ones with steadily high values of the spike length and the number of spike grains, as having a high adaptive response to cultivation conditions.Conflict of interest: the authors stated that there was no conflict of interest.

<p>The North-East of India has been a hotly debated territory of India with voices coming up from different states such as Nagaland, Manipur and Assam demanding separate nations for themselves. These separatist agitations have got further confounded with a constant influx of Muslim immigrants from Bangladesh which began to impinge on the local cultural identities and demographics. This resulted in a prolonged militancy coupled with agitations yielding space for the Pakistani/Sri Lanka/Bangladesh based militants to infiltrate into India through porous borders of the North East and engage some disgruntled ultra outfits in the North East to wage a battle against India. In fact, Naga agitation for separate country bears a lot of similarity with the LTTE’s struggle for separate Eelam in Sri Lanka. Both have a lot of diaspora support and web-based campaign movements (Maya Ranganathan, 2010: 127-149). All these developments have complicated the prospects of the economic and industrial growth in this region. This resulted in the staggering illiteracy and unemployment for over a decade. Towards addressing the problems of the region, the government of India has taken a political decision to establish as many as seven central universities under its direct funding to ensure that the region gets the best education which might contribute further for enhanced employment opportunities in the region. Also, various department under Assam Government such as the Tourism Department, Health Department, Education Department, Social welfare Department etc has been provided with e-governance facilities for the users. The study assumes significance from the point of view that how far the e-services of various departments leads to the sustainable growth of the state and what is the role of media, government and educational institutes to improve the sustainable growth of the states through e-services.</p>

Break Up

The mid-winter break-up of a competent river ice cover can cause ice jamming and flooding, which can have profound impacts on the structure and strength of the ice cover. This research identifies 52 mid-winter break-up events in western Canada (1950–2008) and Alaska (1950–2014) and evaluates the hydro-climatic drivers including temperature and precipitation. The identified mid-winter break-up events are primarily located in the temperate zone, defined as the region between 400 and 1,000 winter (December–February) freezing degree-days. Further delineation by terrestrial biome revealed considerable variability in hydro-climatic triggers, particularly the role of freeze-thaw days (Tmax &gt; 0 °C and Tmin &lt; 0 °C) in Tundra and Boreal Forest/Taiga biomes and short-term (3-day) warming events in Temperate Coniferous Forests and Temperate Grasslands, Savannas, and Shrublands. The classification of 5-day sequences of mid-tropospheric circulation indicates that a persistent trough of low-pressure over Alaska and the North Pacific is the dominant pattern preceding mid-winter break-ups. Furthermore, the trough is stronger for events in British Columbia and Alberta compared with Alaska and the Yukon. The results of this research improve our understanding of the hydro-climatic conditions that generate mid-winter break-up events in western Canada and Alaska and will aid in the prediction and risk management of such events.

Biological Weathering

The study of suspended solids in the West Siberian rivers is of great importance from the point of view of biogeochemistry, since in the rivers there are the formation and transformation of abrasion products of banks and bottom, suspended and dissolved organic matter and solid river flow, which are carried out from the land to the Kara Sea and further to the North Arctic Ocean. Studies of river suspension are necessary to understand the processes of modern sedimentation, as well as for the ecological assessment of the water area state. Mechanisms of sedimentation are largely associated with the processes of physical and biological weathering, generation, transformation and transport of suspended matter from the catchment to floodplain landscapes. In this regard, the role of studying the connection of the qualitative composition of river suspended matter with landscape parameters (level of the catchment area swappiness, nature of the soil cover, composition of soil-forming rocks, presence (absence) of permafrost, etc. is high. For example, the river of the north-taiga subzone, the catchment area of which is heavily swamped, and the river of the tundra zone with a slightly swampy watershed are represented. The influence of flood waters on the concentration of some elements in rivers with contrasting watersheds is considered. The contribution of groundwater and the effect of soil solutions on the overall migration flow are estimated.

Direct Sowing

The variability of morphometric indicators of typical chernozems is considered based on long-term field experiment in a grain 4-field crop rotation (winter wheat, corn, barley, peas) to assess the impact of plowing as a traditional farming system that uses soil treatment and no-till, in which plowing is not used. On the example of four experimental fields (each with an area of 2.4 hectares), the variation of indicators associated with the features of the soil cover structure and the applied farming systems was revealed. The tillage leads to an increase in the thickness of the soil profile leached from carbonates, and direct sowing leads to its decrease. The highest variability degree is found in the boiling depth of soil. It is shown that the tillage leads to the homogenization of the soils surface layer and the transformation of the soil cover structure, as a kind of ”insurance system " against weather risks reducing its effectiveness. The direct sowing usage leads to the restoration of degraded properties and natural of soils heterogeneity in the soil cover structures, which can be considered as a process aimed at ecological improvement of both specifiс soil sites and the soil cover structures. The mutual influence of the soil cover structure and agricultural systems can be traced in time and space. The soil structure and the cultivated crops yield related to the sustainability of agrosystems to adverse climatic conditions and other risk. For these it is necessary monitoring soil as the basis for the qualitative assessment of soil and selection of the most optimal directions of agriculture development, a new technologies development in the production of agricultural products.

Introduction. Currently, one of the directions in medicine is the study of the issue of the quality of life of patients. This indicator is a complex characteristic in terms of the physical and psychological component of health. The state of health is influenced by many factors and one of them is the peculiarities of the climatogeographic region where a person lives. The conditions of the Far North are characterized by extreme climatic and industrial conditions. In such areas, a rotational method is used, which assumes distance from the permanent place of residence. Thus, the influence of the climatic conditions of the Far North on the quality of life of respondents working on a rotational basis determines the relevance of this study, which was carried out in the Khanty-Mansi Autonomous Okrug — UGRA (KhMAO — Ugra).The aim of the research was to study the quality of life of respondents working on a rotational basis in the Far North.Materials and methods. Only men took part in this study — 207 people working in the conditions of the Far North (KhMAO — Ugra) on a rotational basis. All respondents were divided into four age groups: group 1 — 24–28 years old (n=36); group 2 — 29–34 years old (n=63); group 3 — 35–38 years old (n=78); group 4 — 39–45 years old (n=30). The duration of follow-up ranged from 1 to 3 months. A simple survey of all respondents was used to obtain information. In order to study the quality of life (QL) of those working in the Far North on a rotational basis, the MOS SF-36 questionnaire was used. Statistical analysis was performed using the STATGRAPHICS 12 Plus for Windows software in accordance with the general principles of QOL research in medicine.Results. With a long stay in the Far North, a restructuring of the adaptive mechanisms is noted, which goesthrough several stages: initially, minor physiological changes are noted that do not lead to serious changes in the body systems. The second stage is characterized by stable working capacity, but already there is a decrease in health indicators on all scales of the SF-36 questionnaire. The third stage or period of uncompensated fatigue is characterized by a significant decrease in psychological and physical indicators. Conclusion. Unfavorable from the point of view of the medico-biological aspect in the work on a rotational basis in the Far North is the coincidence of the period of work with the phase of the greatest adaptation falling on the first month of stay in the North.
