The presence of metals in aquatic environment is known to cause several health problems to animals and human beings. The levels of heavy metals in wastewater and drinking water must be reduced to the maximum permissible concentration. Clays are abundant and inexpensive layered alumino-silicate minerals that have adsorbent properties. In general, chemical species can interact with clays either by ion exchange or physisorption, both being reversible processes. Among the mineral clays, smectites, especially montmoril...

LEGISLATIVE ASPECTS OF SPATIAL DATA PUBLICATION

(STEF92 Technology, 2017-06-20, Vondrakova, A., Netek, R., Pohanka, T., Pour, T., Malacka, M.)

Show more

In spatial data processing, the area of legislation is crucial but often neglected by the expert's community. Knowledge of the various legal aspects related to the data collection, data processing, and analysis of data, as well as publishing the results of spatial analysis and its visualization, is an essential prerequisite for effective work. Legislative aspects are understood as a set of legislative standards, their relationships and their influence on other fields of human activity. In the context of geoinforma...

ROLE OF THE CALEDONIAN AND VARISCAN OROGENIES IN SHAPING THE EAST EUROPEAN PLATFORM IN POLAND

(STEF92 Technology, 2017-06-20, Golonka, J., Barmuta, J., Krzywiec, P., Pietsch, K., Papiernik, B.)

Show more

The East European Platform (EEP) in Poland belonged to Baltica plate during Cambrian and Ordovician times. Baltica originated as a result of disintegration of supercontinent Pannotia, which occurred during Early Cambrian. Baltica included part of Poland and adjacent areas northeast of Teisseyre -Tornquist zone. This zone is associated with Teisseyre - Tornquist Line, which ran from Scania through Western Pomerania, central Poland to the Black Sea. The Baltica plate originally included also area south-west from thi...

IMPROVEMENT OF SOIL HEALTH AND QUALITY USING COMPOST APPLICATION IN WHEAT CROPPING SYSTEM - LYSIMETRIC EXPERIMENT

(STEF92 Technology, 2017-06-20, Moraru, Ioana, Ciuciuc, E., Hladky, J., Kynicky, J., Brtnicky, M.)

Show more

Depletion of soil fertility due to decrease in soil organic matter content represents a considerable problem in both developed and undeveloped countries. This paper deals with the comparison of compost (Cp) and mineral nitrogen fertilizer (NF) application on selected soil parameters which indicate state of soil environment, its health and quality. The main objectives of this study were (a) to investigate influence of Cp and NF application on total nitrogen (TN) and carbon (TC) content in soil (b), to determine pos...

ANALYSIS OF THE POTENTIAL OF FOREST BIOMASS USING GIS

(STEF92 Technology, 2017-06-20, Gergelova, M., Kuzevic, S., Kuzevicova, Z.)

Show more

Use of biomass for energy purposes is one of the viable priorities of the energy and forestry policies of the state. Given the expanse of forest in Slovakia include the forest biomass among one of the best renewable energy potential. It is used in the traditional way as it is burning, but also further processing of the products in the form of pellets or briquettes. Appropriate are also fast-growing trees. Currently, large amounts of available biomass are unused. These are mainly so-called biomass waste residues of...

MACROMYCETES SPECTRUM UNDER CONDITIONS OF FOREST STANDS OF PROSISKO NATURE RESERVE (SLOVAK REPUBLIC)

(STEF92 Technology, 2017-06-20, Pavlik, M., Kmet, J., Bukharina, I., Sulekova, M.)

Show more

Protected natural areas are ideal for monitoring relatively undisturbed natural development of both inorganic and organic parts of ecosystem. The stock-taking of species occurring in the nature reserve is not only crucial to maintain the function of natural reserve, but also to monitor the development of species spectrum, as well as the diversity and succession under conditions relatively undisturbed by anthropogenic factors. Prosisko nature reserve was established in 1998 in order to protect forest ecosystems wit...

CONTINUOUS MONITORING EQUIPMENT CALIBRATION OF THE DUST AND GASEOUS COMPOUNDS EMISSION FROM A CEMENT PLANT

(STEF92 Technology, 2017-06-20, Ciobanu, C., Voicu, G., Toma, M.L.)

Show more

This paper aims to bring the latest information on annual calibration of measuring equipment installed in cement plants. Calibration should be certified to confirm the quality of continuous measurements, namely the measurements of plant equipment is controlled by parallel measurements with standard reference methods by an authorized testing laboratory (accredited). These types of measurements are referred to as instant annual measurements or measurements for the chimney testing. A continuous emissions monitoring e...

Industrial history of many places still interacts with the present time. Ostrava (Czech Republic) as former industrial city is a typical example of problems and barriers which can be found in process of regeneration, revitalization or redevelopment of areas used formerly for heavy industry. The article is focused on retrospective description of development of areas which can be known as backfields or mega sites. The article will be focused on five areas for which there are expectations and likely huge potential fo...
