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.

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.

<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>

Purpose. The study is aimed at revealing the structural regularities and variability of the fields of temperature, salinity, the colored dissolved organic matter and total suspended matter concentrations, and also the factors that form them in the Sivash Bay. Besides, the results obtained are to be compared with the already known features of the fields of the values under investigation which are typical of the Azov-Black Sea coastal zone; and the response in the considered fields to the North Crimean Canal damming is to be assessed. Methods and Results. Based on the data of 8 expeditions carried out by Marine Hydrophysical Institute in 2013–2016, the structural regularities and variability of the fields of temperature, salinity, the colored dissolved organic matter and total suspended matter concentrations, and the factors that form the fields of these values in the Sivash Bay were revealed. The quantitative indicators of changes in the fields of the considered values, which arose after the North Crimean Canal was dammed, are represented. Conclusions. In the region under study, a number of constantly acting factors that determine formation of special, not typical of the coastal area, features of the oceanological values fields are identified, namely: the influence of the Azov Sea and the North Crimean Canal waters, the rivers inflowing to the water area of the Sivash western coast, the isolated lakes, the swampy shallow bays and the isolated, relatively deep, parts of the coastline. Three years after the North Crimean Canal was dammed, in the northwestern Sivash salinity increased by 20 PSU. The opinion that Sivash is not a typical sea bay, but a connected with the Azov Sea reservoir with the signs of a salt swamp is confirmed

The article is devoted to the study of the role of the North Caucasian muslim factor in the Astrakhan region in the late XX - early XXI centuries. It is concluded that the reduction in the number of traditional population groups against the background of a strong migration flow over the past two or three decades (especially from the North Caucasus) changes the ethnic situation in the region and the interethnic balance in the direction of migrants. In many ways, it was in connection with the influx of migrants from the North Caucasus to the Lower Volga region at the end of the XX century that the ideas of radical islam began to penetrate the region. Key words: Astrakhan, islam, muslims, migrants, salafism, North Caucasus, sufism

The vast catchment area of the Lake Ladoga is characterized by variety of underlying surface types and a complex hydrographic network. The processes of eutrophication of the southern littoral areas of the Lake Ladoga determine the relevance of assessing the removal of solid matter from the river flow to the estuaries of the tributaries of the Ladoga. Observations of sediment runoff of the main tributaries the Lake Ladoga were not carried out. In this regard, for each tributary were selected rivers-analogues the main criteria in the selection was the slope, the grain size of sediments and the catchment area (water availability). The modeling of annual solid runoff and turbidity of the Ladoga tributaries is based on an analytical formula for sediment flow by M.V. Shmakova and a stochastic model of annual solid runoff (M.V. Shmakova). According to the calculations, the annual flow of sediment entering the Ladoga water area is about 432 thousand t/year. The main sources of sediment are three major tributaries of the Lake Ladoga – the Svir, Volkhov and Vuoksa rivers, which account for 253 thousand t/year or 59 % of the total amount of sediment received in the lake. However, these watercourses have the smallest annual module solid flow, due to retention of sediment of backwater areas before hydroelectric dams on these rivers and as a consequence, a decrease in the overall sediment discharge. At the same time, the average annual solid runoff modulus for the Ladoga lake catchment area is 1.53 t/(km2·year), which corresponds well to the previous estimate of this value for the territory under consideration. The analysis of the annual module of solid runoff showed a good correspondence between the obtained values of this value and the conditions for the formation of solid runoff in the catchment, the characteristics of its soils.

The story about the vision of Cyril Belozersky is the first description of the Virgin’s appearance, indicating the place of the monastery’s foundation, in Russian hagiography. The text of this story is read in the North Russian Lives of the monasteries’ founders: Therapont Belozersky’s, Alexander Svirsky’s, Ephraim of Perekom’s, Cyril Novoezersky’s, Philip of Irap’s. From our point of view, there is a process of mastering by hagiographers the episode of the vision from the Life of Cyril Belozersky as a literary device for constructing the situation of the ascetic’s religious retreat in the listed monuments. In them the story of the vision is introduced by the authors in the narrative when the title character for some reason cannot make religious retreat, and this vision helps him to achieve what he wants. There is a similar plot schemes in these Lives, but the borrowed episode is used differently by their authors. They use it in accordance with the characteristics of the ascetic’s holiness. From this point of view, we have already examined the using of the plot fragment from the Life of Cyril Belozersky in the Life of Therapont Belozersky. The author of Therapont’s Life introduces Cyril and almost literally replicates description of the saint’s religious retreat from his Life without making Therapont the visionary. The story about the vision of Cyril Belozersky in the Life of Alexander Svirsky is used otherwise. In this article the analysis episodes of Cyril and Alexander’s religious retreat reveals the role of a similar story in the concept of two different Lives. In the Cyril’s biography, the observed vision marks the stage of the ascetic’s transition to the foundation of the monastery. This is the main achievement of Cyril. In the Life of Alexander, a similar story marks only one stage of the ascetic’s spiritual path. Alexander, like Cyril, became the founder of the monastery. But above all, he is known as the visionary of the Holy Trinity. This vision is the most significant in the concept of his Life. The most important stories of the visions in the Cyril and Alexander’s Lives had influenced the iconography of the saints becoming the basis for popular iconographic versions of compositions “The Apparition of the Virgin to Cyril Belozersky” and “The Apparition of the Holy Trinity to Alexander Svirsky”.

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.
