Analysis of lithodynamic flows and soil-reclamation studies, based on the plastic relief map, allowed for a systematic analysis of the main components of the natural environment. The ways of migration of chemical elements in the soil are established. For the first time, causal relationships of spatial differentiation of the degree and chemical composition of saline soils in the Zarafshan river valley were revealed. The Zarafshan river basin has a clearly defined border, as we can judge from the map of plastic relief made up in 1: 100 000 scale. Here three cascade systems are well distinguished, which is very important for the formation of the reclamation state of the territory. In this area, that is, the subsystem, on the proluvial-alluvial deposits is the main volume of groundwater, which is closely related to the surface. This subsystem is part of the catchment area of the Zarafshan river basin, which is the main source of removal from the territory of a huge mass of dissolved and solid substances.

Mansi folklore is the richest material for research in the field of folklore, linguistics, ethnography and other sciences. Comprehension of folklore genres and images opens new boundaries for the study of representations reflected in codes and symbols. The characters of folklore are people, animals, elements, fantastic (mythical) creatures. In this article we will focus on one character - Miskhum. In Mansi folklore, he is presented as a forest man, whose main function is to help forest dwellers, hunters, disadvantaged orphans. Miskhum belongs to a local group of characters living in the forest. Extensive information about him is contained in fairy tales, stories and myths. The aim of the study is to conduct a systematic analysis of the image of Miskhum on the material of folklore texts and folk ideas. The research materials were field material of the author, as well as the texts of Mansi fairy tales published in various folklore collections, in periodicals. This work adds to the scientific knowledge about the Mansi folklore. For the first time, on the basis of folklore, linguistic and literary data, the image of a forest man is subjected to system analysis, and its functionality is revealed. The anthropomorphism of the image, its desire for socialization, distinguishes the folklore image from the mythological. Possession of the ability to metamorphosis, the desire to provide assistance, to bestow people with magical objects and abilities, all these qualities allowed Miskhum to be elevated to the rank of higher beings. In the traditional views of individual local groups, the Mansi Miskhum is exalted to the status of a patron spirit. The complex of prohibitions, ritual actions, the system of amulets existing in the Mansi determine the boundaries and degree of human interaction with Miskhum. The material opens up possible prospects for continuing research into the character and plot structure of Mansi folklore.

Disaster floods on the Carpathian rivers and surrounding areas as a result of radial and lateral erosion have predetermined to significant changes in geomorphological levels: the rivers bottom in some areas deepened to 100 cm or more, the coastline has shifted to 15–20 m, landslide processes first of all on the shores was invigorated. Due to the flooding in 2008 the soil and vegetation cover of the floodplains was completely destroyed, where the surface alluvial sediments and, often, the bedrock of the river valley went out. To prevent the river influence on the floodplain, the floodplain has become a terrace, so from this moment the alluvial soils have changed their place in the classification system. Pedogenesis in the river valley is certainly correlates with the specified geological and geomorphological processes, and therefore one question arises: in which taxonomic of soil classification the soil is, which now is located outside of floodplain, but the time that has passed from this moment is too short for the genesis of the first terrace soil (formed before our eyes). Shall we talk about the ancient age of alluvial deposits if they were formed in the last 100–1000 years? It is apparently that we need to consider the simultaneous genesis of thesediments, the landforms and the soils under the influence of the geological processes. We have studied the valley of the river Lyuchka, belonging to Prut River basin. We have described the soils that are placed on the ecotopes that have a direct contact with a coastline of the river, on different height levels above the top of watercourse, as well as the cuts of zonal soils which were not under the influence of the river during of the historical time. Soil samples for analytical studies have also been selected. We have studied the cuts of such soils: 1) В-6, К-1 and К-2 – zonal; 2) В-1, В-2, В-5 and В-7 – soils placed on the first terrace; 3) В-3, В-4, В-2а and В-3а – soils placed on the floodplains. The results obtained are summarized as follows. Soils of Lyuchka valley are developing on the alluvial deposits under which the bedrock are placed that in the area of research is clayey flysch; all these soils are on the development stage. Soils of the first terraces are Fluvisols on the complex alluvial deposits, mostly they have the average thickness and the soils are characterized of such morphometric features: humus horizon is from 33 to 66 % of the thickness of profile and transitional horizon is from 34 to 67 % of the thickness of profile. The problem of their selection is establishing of the age, because for alluvium is not specified definitions of "old, ancient". It really could be aged of alluvial deposits are a hundred-thousand years or even as whole Holocene. Another problem is a quick output time of the floodplain from the influence of the river and the formation of the first terrace. This requires a change of the name of the soil (maybe the output from Fluvisols). It remains an open question whether this change of belonging of classification reflects the inner essence, and whether all the soils of river valleys should be admitted young, genetically related (monogenesis) and therefore whether they should occupy one position in the classification system.

The article continues the author's research on the toponymy of the North-East of the Sakha Republic, in particular the Kolyma river basin, in the aspect of the interaction of related and unrelated languages. The relevance of this work is defined in the description of local geographical terminology of Yukagir origin, as a valuable and important material in the further study of toponymy of the region. For the first time, the toponymy of the Kolyma river basin becomes the object of sampling and linguistic analysis of toponyms with local geographical terms of Yukagir origin in order to identify and analyze them linguistically. The research was carried out by comparative method, word formation, structural, lexical and semantic analysis. As a result of the research, phonetic and morphological features are revealed, the formation of local geographical terms and geographical names of Yukagir origin is outlined, and previously unrecorded semantic shifts and dialectisms are revealed. The most active in the formation of terms and toponyms is the geographical term iилil / eҕal 'coast‘, which is justified by the representation of the Yukagirs’ coast' home, housing

Social Forestry (SF) schemes have been implemented in India since the 1980s to combat deforestation, increase the supply of fuel-wood and fodder, and provide minor forest products for the rural populaton. The relevance of such Schemes in the Mayurakshi River Basin is basically due to its environmentally degraded state. Latterly the Basin has been brought under the Mayurakshi River Valley Project, but unless measures are undertaken to mitigate problems of soil erosion, the efficiency of the Project will be hampered.

The single crystals of langbeinite-related K2BiZr(PO4)3 have been obtained for the first time by spontaneous crystallization method from K-Zr-P-O-F molten system. The compound crystallizes in a space group P213 with cell parameter a = 10.30360 Å. The framework is built up from isolated Bi/ZrO6 octahedra connected together by PO4 units. For the two K+ cations two types of oxygen coordination numbers 9 and 12 are observed. The photoluminescence (PL) spectroscopy studies of K2BiZr(PO4)3 are carried out under the VUV synchrotron excitations. The electronic structure of K2BiZr(PO4)3 crystal is calculated by the FLAPW method. The PL spectra reveal two main components in the UV and visible spectral regions (peaking near 3.6 and 2.7 eV respectively). It is assumed that the <st1:address><st1:street>UV PL</st1:street></st1:address> component of K2BiZr(PO4)3 originates from transitions in ZrO6 polyhedra, while the visible one is related to Bi3+ ions in oxygen coordination.
