The Moravian Karst, situated in the eastern part of the Czech Republic, is the most extensive and most developed karst area in the Bohemian Massif. To protect its unique environment, the Moravian Karst was declared a Protected Landscape Area in 1956. Despite the protection, pollution occurs in some disappearing streams both on the earthпїЅs surface and underground, in caves formed by karst processes. The aim of the study was to assess the hydrochemical status of several selected streams and identify the sources of...

According Act No. 157/2009 Coll., on mining waste management, the Czech Geological Survey carried out a project of the Operational Programme Environment in 2010пїЅ2012. The project was entitled пїЅInvestigation of closed and abandoned mining waste facilities posing a serious threat to the environment or human healthпїЅ. The aim was to create an inventory of hazardous mining waste facilities and to develop a methodology for their assessment. In the Czech Republic, 300 potentially hazardous mining waste sites were i...

The paper deals with the fundamental rule of extensional logics, namely the rule of Existential Generalization. This rule can be applied in the situation when a function f is applied on its argument a to obtain the value of f at a. If the application does not fail, i.e., if the function f is defined at a, then we can existentially quantify, and derive that there is the value f(a). Our system is based on Transparent Intensional Logic (TIL). Since TIL is a hyperintensional, partial, typed lambda calculus, we examine...

The article presents selected results obtained by using of electrical resistivity tomography method in searching of different, mostly anthropogenic objects at shallow depths. The anticipated depth of the object is up to 20m. These objects are relatively small with dimensions up to maximum in first meters in diameter. In terms of the shapes of these objects it is possible to define two groups. The first group consists mainly of the objects whose shape can be replaced by a vertical or horizontal cylinder. The second...

The results of research studies from deformation investigation of geotectonic recent movements in east Slovakia are presented. Satellite measurements were implemented in the geodetic network in the Kosice Basin. Transformation of the geodetic points coordinates from WGS-84 into the Slovak national positional coordinate and height system was carried out using Helmert seven-element transformation. The aim of the deformation measurements was determining geotectonic recent movements especially in the urban agglomerati...

This article is the continuation of the paper published at the conference SGEM in 2016. European product standards generally do not specify the qualitative requirements for individual product characteristics. EN 14695:2010, which deals with the waterproofing of concrete bridge decks, is not an exception. The national standard CSN 736242:2010 sets quality requirements for bitumen sheets. The type of the modification of bitumen coating is not considered in quality requirements of this standard - the mass modified by...

In the Czech Republic, the production of energy using fossil fuels - particularly coal - is still a major proportion of total production. The energy sector is and will remain one of the most important areas of the Czech economy, ensuring supply of electricity and heat to the population and industrial enterprises. In the power and heating plants is burned primarily domestic brown coal mined in opencast mines in the north-western part of the Czech Republic, namely, Usti Region. For combustion of biomass in the Czech...
