NUMERICALLY-ANALYTICAL MODEL OF TWO-LOOP DIPOLE PROFILING TECHNOLOGIES OF VERTICAL AND STEEPLY THIN CONDUCTIVE INCLINED SEAM BY TRANSITION PROCESS

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

The paper considers the mathematical models of transient electromagnetic field of the horizontal electrically conductive seam excited by a horizontal magnetic dipole, based on which with the help of images and numerical experiment method a new mathematical model was developed describing the transient electromagnetic field of steeply thin conductive inclined seam excited by a vertical magnetic dipole – the analytical description of the technology of dipole version transients, provided mainly by physical modeling. The results of the mathematical modeling correspond to the theoretical foundations of the method, the data of physical experiments and theory of “related” technology – modifications of dipole electromagnetic profiling.

APPROBATION OF METHODS OF LONG-TERM FORECASTING OF STATISTICAL CHARACTERISTICS ON RIVER BASINS OF IRAN

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

The article considers the possibility of applying the methodology for assessing consequences of the climate change to the river basins of Iran. The paper investigates Sefīd-Rūd and Kārun river basins. Approbation of the technique was performed with the help of retrospective material with the identification of low-water and high-water content phases with the aim of simulating climate change conditions. The forecast method is based on the Fokker-Planck-Kolmogorov equation. According to the results, reliable estimates of statistical characteristics of the river flow in Iran, it is necessary to use regional dependencies for the parameters of the forecast equation.

WAVE DYNAMICS OF EXPONENTIALLY STRATIFIED MEDIUM

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

The problems of internal gravity waves dynamics in unbounded exponentially stratified medium are considered. We discuss the relevance and limits of applicability of the used stratified medium model. The basic qualitative features of the internal gravity waves plane packets dynamics are obtained. It is shown that internal gravity waves in an unbounded exponentially stratified medium qualitatively differ from acoustic and electromagnetic oscillations. The frequency of propagating internal waves oscillations can not exceed the buoyancy frequency. Internal gravity waves propagate not along the normal to the wave fronts.

MORPHOMETRIC ANALYSIS OF LEALANDS AREAS IN AGRO-LANDSCAPES OF CENTRAL BLACK SOIL REGION

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

High-resolution space images have detected more than 2,500 sites of abandoned arable land in the Belgorod Region and neighbouring administrative districts of the Kursk and Voronezh Regions. The share of localized lealands in 33 municipal districts and in the urban districts of the central part of the Russian Federation is estimated in the paper. Morphometric analysis of the sites of localized lealands was carried out according to the main indicators: Slope, exposure, height above sea level. Combinations of morphometric conditions that contribute to the abandonment of arable land in agro-landscape areas of the forest-steppe are revealed. It is shown that in order to create a representative network of supporting (key) lealand areas, sites located on the slopes of the south-western, southern and south-eastern exposition should receive the bigger share, and attention should be paid both to sites with a slope of more than 3 degrees, and relatively flat areas (slope up to 2 degrees).

OBTAINING PECTIN FROM BEET PULP

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

The paper contains the results of pectin extraction from beet pulp – the waste of sugar production. The conditions of performing extraction are optimized in order to obtain greater yield of pectin. We have developed the block diagram of obtaining pectin from beet pulp with a pectin yield of 21…29%. Obtaining pectin will allow refusing from import of this product from abroad, as well as reducing negative impact of sugar plants on the environment. The article offers an environmentally safe scheme.

PECULIARITIES OF MINING AND RECREATIONAL COMPLEXES DEVELOPMENT IN MODERN SOCIETY: LANDSCAPE APPROACH

Posted in 2017, Issue № 4(58) April 2017, SCIENCES ABOUT THE EARTH | 0 comments

The assessment of touristic and recreational potential of the territories is a topical issue of modern recreational geography. Most of the methods of such assessment are based on the integral-factor approach. The application of landscape approach in the assessment of touristic and recreational potential and the peculiarities of tourism development enables abandoning labour-intensive process of analyzing certain geo-system factors. We can, instead, move on to other principles of recreational zoning. In particular, this approach is relevant for mountain-recreational complexes, characterized by contrast and mosaic landscapes.
