TO RECENT BASE FOR PALEOECOLOGICAL RECONSTRUCTIONS BASED ON HUMUS OF URAL PALEOSOLS [№ 12 ' 2017]
When carrying out the reconstruction of the natural environment of the past by paleopedology methods the humus composition is used as one of the significant diagnostic features. Interpretation of materials is based on the recent basis — similar characteristics of modern soils of different formation conditions on both the territory of location of the paleosols and adjacent to them. Revealing the Holocene-Pleistocene evolution of the Ural natural environment requires the materials of exploring the specific features of the humus composition of different types of soils in its different regions including the Middle Urals for which data on humus are not generalized. On the basis of the original and literary material data generalisation of the humus composition specific features of the modern Middle Ural types of soils, the closeness of most humus characteristics and the reliable differences of some of them in the most common in this region plain sod-podzolic and brown mountain-forest soils are revealed. It was established that the differences in the content of individual groups of humus substances and the integral index Cha:Cfa are unreliable. Significant differences were revealed only for the following characteristics of humus composition: the content of total organic carbon, as well as FA1a, FA2, and FA3. The parameters of the composition of humus in gray forest soils of the Middle Urals are typical for similar soils of other regions of the Urals and adjacent territories. The obtained limits of variation of the integral indicator of the composition of humus in soddy-podzolic, brown mountain-forest and gray forest soils of the modern Middle Urals, will allow to reconstruct the conditions of humus formation in paleosols in similar bioclimatic conditions. It has been established that the sod-podzolic and brown mountain-forest soils of the Middle Urals, forming within the boundaries of a single bioclimatic zone at different positions in the relief, have close characteristics of the qualitative composition of humus.

PALEOECOLOGICAL CONDITIONS IN SUBBOREAL SUBATLANTIC PERIODS AND FOREST-STEPPE ZONE SOUTH URAL [№ 10 ' 2015]
The peculiarities of composition and properties of paleosols exposed in Baturino quarry and archaeological site Stepnoe-7 in the Southern Urals are studied. Diagnostics of paleoecological conditions in the Subboreal and the Subatlantic periods within the modern forest-steppe of the Southern Urals was carried.

URANIUM AND THORIUM CONTENT IN THE HUMIC ACIDS OF PALEOSOLS BURIED UNDER BARROWS AND CULTURAL HORIZONS OF ARCHAEOLOGICAL OBJECT STEPNOE 7 (SOUTHERN URALS) [№ 10 ' 2013]
In this paper the contribution of humic acids in the total soil pool of radioactive elements U and Th was estimated on the example of paleosols, buried in the Bronze Age, the cultural horizons of the same time and territorial localization, as well as modern background soils in forest-steppe conditions of Southern Urals.

HUMIC ACID ELEMENTAL COMPOSITION OF DIFFERENT FORMATION CONDITION VIRGIN CHERNOZEMS [№ 10 ' 2012]
Humic acid element structure characteristics of virgin chernozems of different regions (ETR, Southern Ural, Western Siberia and Mountain Altai) and different formation conditions are discussed. It is shown that the mass percentages, share of individual element content and their relationship clearly responsible landscape conditions. Materials can serve as a basis for assessing agricultural land and use for revealing of anthropogenic transformation specificity and diagnostic environment as well.

THE INFLUENCE OF STRUCTURE OF THE SHARE CAPITAL ON RESULTS OF ACTIVITY OF THE COMPANIES [№ 6 ' 2003]
The traditional approach to the analysis of influence of structure of the share capital on results of activity of the company is investigated. In opinion of the authors, the given approach is excessively narrow. The carried out analysis has shown, that at an estimation of influence of structure of the capital on activity of the company the big value has not only the size of a share of the capital of the shareholder, but also functional value of the shareholder for the company.

THEORETICAL AND METHODOLOGICAL FOUNDATIONS AND HYPOTHESES WHICH RESEARCH A PERSONTS VITAL WORLD CHARACTERISTICS [№ 7 ' 2002]
The article examines some theoretical and methodological foundations while researching a personTs spatial and temporal organization. Some theoretical proposition of self-organizing psychological systems are examined as these foundations. The article also gives some hypotheses which research the personTs vital space characteristics.
