It is called stress when an individual begins to act different physically and mentally as a result of the fact that he or she is affected by the environment he or she lived and worked in. To block or balance the process of adaptation to stressful circumstances of people can be in different ways. However, it may not be possible to get rid of stress completely. So that, an individual who is overstressed can suffer aggressiveness, nonconfidence, difficulties in focusing, chronic tiredness, tension, sadness, anxiety, ...

Approximately 110x106 m3 of oil (100x106 tons) had been recovered from 38 fields in the Croatian part of the Pannonian basin during more than 60 years of exploitation (1941-2003). Based on their cumulative production, number of reservoirs, average porosity and permeability, obtained recovery and depositional characteristics of reservoir rocks, the Croatian hydrocarbon fields may be divided into three groups (oil), or four groups (gas) (Table 1, 2). In the period 1941-1990 the production started in 38 fields, 13 of...

Rural area of Croatia covers 90\% of land in Croatia, and there 47\% of total population living in it. These are mostly poorly developed areas in Croatia, and they are being expanded all the time, which causes the emigration of population. In order to trigger the development of rural areas, some measures are planned, among other things the land consolidation that might increase the economic efficiency of family farms, and hence, prevent the emigration of population from villages. Namely, small family farms being l...

ANALYSIS OF GEODETIC DATA FOR INVESTIGATING POLAR MOTION

(SGEM Scientific GeoConference, 2008, Tsenkov, Tsenko, Gospodinov, Slaveyko)

Show more

Theoretical and experimental investigations have been made to study the polar motion based on the IERS (International Earth Rotation Service) solution. A set of 9 mathematical models is proposed to examine the time series of polar motion. We have proved by statistical tests that the ARMA (2,1) model is the “best” one of the proposed set of competing models. Estimates have been obtained of the spectral characteristics by investigating the cyclic polar motion variations. Criteria are applied to assess the adequacy o...

Analytical model of the stress-deformed state of the rock mass in production mining is proposed. In comparison with conventional ones, the model takes into account the depth of coal extraction, thickness seam and the existence of the total zone of mining subsidence displacement. As is shown by calculations, effect of said factors results in complete reconsideration of the stress-strain state pattern of the rock mass and may serve as the basis for the development of mining subsidence displacement theory.

In the detailed exploration and reserve estimation, with separating the alteration (as the controller of the grade) in ore reserve and estimating the reserve in each alteration, the estimation variance will decrease and the accuracy of the estimation will increase. This paper tries to quantify and separate the alterations using discriminant analysis, a multivariate statistical method, and distribute them through sequential gaussian simulation in the Sungun copper deposit. A simple linear discriminant function tran...

SEQUENCE ANALYSES OF STREAM SEDIMENTS FROM ABANDONED SB-MINING AREAS (POPROC AND DUBRAVA) IN SLOVAKIA

(SGEM Scientific GeoConference, 2008, Sottnik, Peter, Lalinska, Bronislava, Jurkovic, Michal Sutriepka Lubomir)

Show more

Sb-mineralization had been exploited in many localities in Slovakia. Contamination of environment by Sb, As and other heavy metals is specific problem of Slovak mining regions. Natural background for groundwater in Slovakia was appointed to 1 $\mu$g/l for Sb and 5 $\mu$g/l. Two localities Poproc (in eastern part of Slovakia) and Dubrava (in The Low Tatras) are abandoned Mining areas where the stibnite ores had been exploited for many years. These areas represent high potential environmental risk because of transpo...

With regarding to population and increasing growth rate of civilization, one of the ecological problems that bring some difficulties to human being and social life is to produce industrial culch. It is natural that such an increasing growth will bring some difficulties the same as follows: Howe to product culch (rubbishes) and how to resumption them in a good way . The main aim of this research is to find some suitable ways for resumption of the used materials in educational workshops in Golestan province, Iran. T...

Recent data demonstrate a significant capacity of mushrooms to retain the pollutants from soil, so being realised the mycoremediation of soil. Nitrogen oxides are major atmospheric pollutants. The main oxides, nitrogen monoxide and dioxide, penetrated in human body cause important toxic effects: methaemoglobinemia, haemolysis, vasodilatation and even cancerogenesis. The accumulation of these oxides in mushrooms, as nitrites and nitrates, is dependent on: species, environmental conditions and chemical composition o...

ZERO-VALENT IRON AS APPROPRIATE REACTIVE MATERIAL FOR SB AND AS REMOVAL - THE APPLICATION OF INSITU PERMEABLE REACTIVE BARRIER TECHNOLOGY

(SGEM Scientific GeoConference, 2008, B. Lalinska, P. Sottnik)

Show more

Antimony mineralization has been intensively exploited at numerous deposits in Slovakia from 17th century until a while since. Weathering and dissolution processes in the environment of mine tailings and closed mines, mobilize elevated levels of toxic elements such as arsenic and antimony, which represent dangerous contaminants for the surrounding ecosystem. The problem of contaminated groundwater should be solved and one of the possible remediation method is the Permeable reactive barrier system (PRB). The choice...

SORBENTS OF NORTH-WESTERN BOHEMIA, THEIR UTILIZATION FOR RECLAMATION WORKS AND POSSIBILITIES OF SMECTITE STRUCTURE MODIFICATION

(SGEM Scientific GeoConference, 2008, T. Lang, M. Rehor, L. Zizka, V. Cablik)

Show more

Clay sorbents from the North Bohemian Brown Coal Basin represent important but still somewhat neglected accessory raw material. Submitted paper is concerned with relation between mineral structure, sorptive efficiency and reclamation exploitation of these rocks. Characters and localities of main clay sorbents from the North Bohemian Brown Coal Basin are shortly evaluated in an introduction. In next part, methodology of mineralogy survey for these accessory raw materials is stated, it is based on diffract analyse w...

UTILISATION OF RENEWABLE ENERGY SOURCES BY INCREASING ENERGETIC EFFICIENCY IN SLOVAKIA

(SGEM Scientific GeoConference, 2008, Kralikova, Ruzena, Badida, h.c. . . Miroslav, Krupa, Marek)

Show more

Renewable energy source is a source which energetic potential permanently renews with nature´s processes or with the activity of man. Renewable-based energy sources have as yet played a negligible role in Slovakia´s energy balance. However there is the global trend toward more intensive use of these clean energies, therefore their higher utilisation is enshrined among the strategic goals of energy policies of most of the countries worldwide, including Slovakia. Necessity of energy and exploitation of the energetic...
