The use of clover-grasses in the structure of fodder crops grown on arable soil, especially those with intergeneric hybrids as the main component part, could avert the negative current trend, i.e. further decreasing the area of perennial fodder plants or fodder crops as a whole on arable soil. They have an irreplaceable role in crop sequences and in preserving the cultural character of the countryside, above all due to the fact that they improve soil fertility and microbial life in the soil and that they have an excellent pre-produce value, and, at the same time, they are applied in various farming systems (both conventional and ecological) and in various climatic conditions, and agricultural businesses are well equipped for growing, harvesting and storing them. In the Czech Republic, the area of fodder crops grown on arable soil was decreased from 1,019.9 thousand hectares to mere 396.7 thousand hectares between 1980 and 2009, which is 15.6 % of the total area of arable soil whereas perennial fodder plants only take up 8.5 %. Fodder from clover crops and clover-grass growths on arable soil are one of the main resources of voluminous fodder for dairy cows. Most of this fodder is preserved through a fermentation process (silages, hay storage); a smaller part is fed as fresh fodder, or serves for production of hay. Silages made with perennial fodder plants are the most important source of both proteins and other nutrients for ruminants, especially for high-yielding milch cows. The basis of fodder production systems are the conservative elements of the landscape area (geomorphology) in combination with the progressive elements (weather conditions, plants and human labour) and relict ones, the representative of which is the soil. The fodder production systems in Europe are divided into five main fodder production zones. From this point of view, the areas where short-term clover-grass mixtures are grown on arable soil could be classed with Zone 4, i.e. intensive fodder production and cattle breeding. This characterisation corresponds with the Vysočina Region (the Czech Republic), which is the focus of our work even though extensive breeding can be found in this area on a smaller scale as well. Therefore, our aim was to verify the production and qualitative parameters of the fodder crops and mixtures included in the test in chosen agricultural businesses in the Vysočina Region and to recommend the most suitable variant for the given area. A statistically significant correlative relationship (P < 0.05) was proved between the net energy for lactation contents and the percentage of organic matter digestibility. The evaluation of the production parameters evidently shows the favourable influence of the grass component part or of intergeneric hybrids on the stability of dry matter yield per hectare as well as on the stability of individual nutrients.

The Stability

We predict the stability of breeding values (BVs) for direct effect (DE) and maternal effect (ME) for live weights at 210 days of age in the entire population of purebred Aberdeen Angus cattle in the Czech Republic according to an increase of progeny number in performance recording over a period of 11&nbsp;years (1997 to 2007) and the course of BVs for DE and ME during the years of observation in animals born until 1997.&nbsp; Furthermore we compare genetic trends of BVs for DE and ME among animals born in different years and detect the level and significance of correlation coefficients among predictions of BVs for DE and ME performed during the years of observation. The animal model and the BLUPF90 programme were used for these predictions. The used model included the effects of animal, sex, contemporary group, dam, age of dam, and permanent environment of dam. The variance of BVs ranged from 4.96 to 10.87 depending on the year of evaluation and whether it was related to maternal or direct genetic effect. The animals were initially assigned to groups according to their BV in 1997, and this ranking was not affected by the BVs predicted in subsequent years. The existence of a negative correlation between direct and maternal effects was confirmed. The significant correlations (P &lt; 0.0001) demonstrated a strong relationship between the BVs predicted in successive years, e.g. the correlation coefficient for the relationship between BVs for direct effect predicted in the last years of the examined period was above 0.9 and that for maternal effect was above 0.8.&nbsp;

The resistance of concrete constructions to high temperatures at present is a much monitored issue for many scientific teams and experts in the stated area. This fact is mainly caused by fatal consequences originating in the case when concrete constructions are loaded by the effect of fire and consequent loss of their load-bearing capacity, for the population and the environment of our planet, in which we live in. The development of society goes hand in hand with the development of new building materials and as a consequence the requirements for building constructions increase which bring about extraordinary strict regulations in the area of fire safety. So, many high, non-traditional or specific constructions originate, e.g. nuclear power plants due to permanently higher demand for transport linkage and many tunnels have originated between European countries as a result. Unfortunately, in this relation the threat of terrorist attacks increases and unexpected natural disasters which also threaten the stability of the mentioned constructions. The objective of the article is to familiarize readers with the results of research concerning the improvement of the resistance of the concrete to high temperatures originated during fire instances.

Current State

An important characteristic for efficient management of production systems is the ability of a product, component or material to be tracked. That is, to be assigned with a unique symbol, number, or other code (identifier) that can be traced back both within the production process and to the customer (e. g. when complaining about a defective part). Traceability leads to a cost reduction in eliminating the risks associated with the difficult identification of the material or parts, their handling in pre-production, the manufacturing process, or the storage and sale of finished products to customers. In case of problems, it makes it easier to implement the necessary measures and reduces the time to remedy the situation either within the company or even outside. Individual companies within the Czech Republic usually solve the identification and traceability independently. The paper deals with the results of the analysis of the current state of record keeping and identification of metallurgical materials in selected companies, and presents a proposal for improvement of the current situation in a specific company, especially in the field of work with remaining material.

Abstract This paper aims to characterize and interpret the trends in reserves, resources, and in the mine production of crude kaolin and output of beneficiated kaolin between 1999 and 2015 in the Czech Republic. With nearly 1.2 billion tonnes of total resources, kaolin belongs to the key industrial minerals of the Czech Republic. With an annual output of about 3 to 4 million tonnes of crude kaolin and of around 0.6 million tonnes of beneficiated kaolin, the Czech Republic ranks among the top European and world kaolin producers. Mine production of crude kaolin has been relatively stable since 1997, while the output of beneficiated kaolin has been increasing gradually during the same period. The increased production and yield of beneficiated kaolin resulted from the use of progressive methods in kaolin processing, primarily high-intensity electromagnetic separation. The positive growth trend was not a reflection of the stability of the extractive sector and domestic industry, but it was the result of a pro-export orientation. The amount and share of exports are continuously increasing and constitute 80% of the entire kaolin production sector at the present time. The only exception occurred in 2005-2008, when exports declined by one-half as a result of the government´s export restrictions. The results of analyses were not optimistic for the Czech economy and indicated a sharp downturn in the domestic mining industry. Moreover, a similar situation exists in the case of other essential industrial minerals such as feldspar, clays, and silica sand.

The reaction of the Belarusian authorities to the August 2020 demonstrations, drew strong condemnation from the Czech Republic. The article analyzes the reasons for such close attention of the Czech officials to the Belarusian problems. The historical context of the Czech Republic’s support for the Belarusian opposition is outlined; revealed the human rights and value aspects of the foreign policy of Prague, where support for democracy and human rights is an integral feature of Czech diplomacy at its present stage of development. The author examines the «Program of Transformational Cooperation» of the Czech Ministry of Foreign Affairs. He comes to the conclusion that the Belarusian direction has always been among the priorities and has not disappeared from the agenda. However, the stability of the Belarusian regime led to the fact that the Czechs began to contribute to the development of democracy in other countries, where its «implantation» was more real.
