Use of soil conservation technologies in the growing of sugar beet
Hybler, Jakub ; Urban, Jaroslav (advisor) ; Vladimír, Vladimír (referee)
More recently we meet with many extremes of weather. One such are sudden and heavy rainstorms. Now most these rains endanger the agricultural land the emergence of water erosion. Most sensitive to water erosion are wide row crops, including sugar beet also. For these reasons, in recent years we paid great attention to the impact of tillage effects on soil water erosion.
The aim of this thesis was evaluate the influence of autumn tillage on water erosion soil in the stand of sugar beet, but also on the yield and quality parameters of the crop. A secondary aim was to assess the effect of increasing the leafy ground cover beet on water erosion soil.
For this purpose over the years 2012-2015 based on accurate field trials on lands Agro Chomutice Inc. Experiments were set up in three variants namely shallow loosening (10 cm) deep plowing (25 cm) deep loosening (25 cm). In various growth phases proceeds artificial rainfall. In the first growth phase was not sugarbeet involved either in row and not in the between rows. In the second growth phase of the beet involved in the row between rows but not yet. In the third growth phase has been fully involved growth. Itself artificial rainfall was performed field simulator rain and was observed soil loss from individual variants.
At artificial rainfall it was found that sugar beet is the most threatened by water erosion soil in the early growth phase and at this phase the most evident difference autumn tillage to sugar beets. In the first growth phase of sugar beet, which was carried artificial rainfall, the best results both for deep loosening and deep plowing. In 2012 (24. 5. 2012) was measured with a deep loosening of soil loss of 1.30 t ha-1, representing a decrease of 64.76% compared to the shallow loosening and by 40.91% compared to deep plowing. Conversely, in 2014 (2. 6. 2014) was evaluated as the best variant of deep plowing the soil loss of 0.11 t ha-1. Such loss soil is 78.43% less compared to the deep loosening and lower by 91.41% compared to the shallow loosening. Similar results were achieved for both deep loosening and deep plowing in the later phases of growth, which was carried artificial rainfall. From the results it was found that the sugar beet at later growth phases better resists water erosion. This is illustrated in 2012, when the first artificial rainfall (24. 5. 2012) was observed soil loss of 2.20 t ha-1 for deep plowing. In the second artificial rainfall (6. 6. 2012) 0.03 t ha-1, and the third (1. 8. 2012) have been measured zero loss soil. The same results were achieved in the following experimental years.
On deep loosening achieved the largest root yield (99.71 t ha-1), but the difference between deep plowing (99.32 t ha-1) was only 0.39%. The highest sugar content reached variant with deep loosening (18.95%). When the statistical treatment has not been established between the variants statistically significant difference. The greatest yield root recalculated at 16% sugar content reached variant with deep loosening (122.32 t ha-1), but again the difference between deep plowing (119.81 t ha-1) was only 2.10%.
Results from four years has clearly demonstrated beneficial effect of deep loosening and deep tillage on soil water erosion in the sugar beet crop. Furthermore, it was found that with increasing abundances leaf and root growth of sugar beet decreases danger of water erosion. Sugar beet is the most susceptible to water erosion in the early phases of growth, and at this time was applied deep autumn tillage. For a fully wired vegetation were not detected significant loss soil, and at this time ceases to be a dangerous erosion sugar beet crop. For yield and quality parameters of sugar beet was found positive effect of deep loosening and deep tillage on yield and quality of sugar beet. The least favorable results in all experimental years was achieved in a shallow loosening.

Effect of fertilization of permanent grassland on the substrate biogas yield
Stibůrek, Jakub ; Fuksa, Pavel (advisor) ; Jiří, Jiří (referee)
The aim of this study was to extend knowledge about the influence of permanent grassland fertilization on the yield and the quality of biogas.
During the years 2013 and 2014 three levels of fertilization (non fertilized control, N50PK, N200PK) were tested. Samples were taken from the experiment site Černíkovice, Benešov region. For anaerobic digestion, a 40 day mesophilic conditions batch test was chosen.
A statistically significant decrease of substrate biogas yield (SBY) and area biogas yield (ABY) with higher doses of fertilizers occurred between non fertilized control (575.4 ml/g; 3332.4 m3/ha) and N200PK variant (460.5 ml/g; 2605.7 m3/ha) in 2013. The only statistically significant differences in the quality of biogas were found during the first day of anaerobic digestion, when the highest doses of fertilizers caused higher concentration of methane (33.2 %) compared to control variant (22.6 %).
Application of fertilizers had no significant effect on SBY in 2014. Still, the highest SBY was obtained from the non fertilized control (762.7 ml/g) compared to N50PK (707.6 ml/g) and N200PK variant (732.8 ml/g). Furthermore, significant most of the ABY was obtained from the N50PK (2911.5 m3/ha) compared to the non fertilized control (2296.3 m3/ha). The only significant differences in biogas quality were found during the initial 7 days of the test. Most of the methane was contained in biogas from the non fertilized control (59.1 %), and least amount of the methane was found in the N50PK variant (57.9 %).
ABY is highly influenced by the yields of phytomass, which were negatively affected by the late first cut caused by unfavorable site conditions in 2013.
Cumulative biogas production showed that the most important part of anaerobic digestion was during the initial 14 days, which produced upwards of 80 % of total biogas yields in both years.

Music as an Expression of the Lifestyle in the UK in 1960s. Contribution to the European Consumer Society after 1945.
Vlčková, Petra ; Soběhart, Radek (advisor) ; Kozmanová, Irena (referee)
This thesis focuses on the British music scene in the 1960s. Popular music was one of the main manifestations of consumerism and influenced the behavior of most young people. The aim of the thesis is to explain the extent in which popular music played a role in the establishment of a consumer society and, above all, the impact caused by interpreters and music groups on the lifestyle of their listeners and audiences.The thesis also examines how the British music developed in the Sixties and how it was characterized.The thesis is based on the assumption that the 1960s' is a key decade in the postwar history of modern society, a time when fundamental changes occurred in the value systems of most Western societies, notably the British. New generations of young people associated with economic prosperity surfaced at that time, fostering the development of the phenomenon of consumer society, thus changing people's lifestyles.The first part of the thesis is dedicated to economic and social assumptions of the development of the consumer society. The second part of the thesis addresses the social structure of the British society, focusing on the youth - arguably, the social extract that was most appealed by popular music. The core part of the thesis analyses the British music scene in the 1960s, with focus on the music groups and also the music industry and its impal on the lifestyle of youth.

The influence of Representatives of the Czech Republic men's basketball at gaming performance from their parent team
PIXA, Zdeněk
Men's basketball league season from 1998 to 1999 to the present, much has renewed all the monitored indicators - the number of players, minutes played, the points scored and the coefficient of usefulness. The main part is played by the increased interest in the engaging foreign nationals in the Czech teams. Their representation in the NBL increased since 1998/99 from 7.6% to 41.8% in 2008/09. Influence of this growth is there less participation of Czech players younger than 20 years of course and the high fall of the Czechs above 20 years. If you complete the top ten, twenty and thirty of the best players in NBL we´ll have always of predominance by foreigners. But they could be represented only those players with Czech nationality. Question referred to the project is how these best Czech players will stand in the future. The goal is to determine how the ten most representative of players for the last 3-5 seasons affects the game performance in the parent team. The basic method of the investigation will be analyze statistics of the game (technical register) - gaming performance of the individual player representatives (eg in relation to the results of the team, its composition, etc.). The research sample will be composed by the selection of the men's NBL teams, 10 representatives of the Czech Republic, always two to one of the player post. Authenticated facts gathered from the implementation of the project will be provided to the experts through the periodicals.

The history of uranium mining with particular emphasis on the 21st century
FUKA, Stanislav
Uranium is a chemical element with the brand U discovered in 1789 by German chemist Martin Heinrich Klaproth. Initially it was not particularly interesting for mankind, it was used mainly for colouring the glass. A major turning point came after the Second World War, when uranus began to be used for nuclear weapons and later for nuclear industry. At that time Czechoslovakia was the great world power in the production of uranium. The aim of my bachelor´s work is a description of the uranium research characteristics and development of uranium mining in the 20st and the 21st century in the Czech Republic and in the world. An intergovernmental contract between Czechoslovakia and the Soviet Union about an uranium supply was signed in 1945. Jáchymov was the key place for the Soviet Union, there was only a research carried out in other places of Czechoslovakia. There were exported 98 500 tons of the separated uranium ore and the concentrate to the USSR. The uranium industry employed 40 000 people in the fifties of the last century and it should be mentioned that a considerable part consisted of inmates and prisoners. At the turn of the fifties and sixties, the supply for military purposes is filled up and the uranium begins to be used mainly for nuclear energy. The mining is reduced after 1989 mainly due to an overproduction of uranium. The uranium mines are gradually closed and the places of extraction and chemical finishing departments of the ore are recultivated. The only mine, which is still in operation, is in Dolní Rožínka in the Bohemian-moravian highlands. A significant problem nowadays after the extraction seems to be the location of Stráž pod Ralskem, where the uranium is mined by the method of chemical infusion (In Situ Leach), and the chemical finishing department of the ore, mainly a MAPE Mydlovary. The price of remedial work estimated at 40 billion Czech crowns in Stráž pod Ralskem and will last approximately for the next 20 years. Redevelopment in the 5 MAPE Mydlovary is estimated in the tens of billions of Czech crowns and it will take about another ten years. Bachelor´s thesis is divided into two parts. In the theoretical part, there are described the sources and methods of uranium mining, the concepts of radioactivity, uranit. After that there is described the current state of environmental burdens in the MAPE Mydlovary in Českobudějovicko. In the practical part I deal with the issue of the impact of uranium mining on man and the environment, the development in uranium mining in developing countries and the perspective of the extraction and a comparison of the uranium reserves in the Czech Republic and in the world. A section of the practical part follows up the development of the price of uranium in world market.

Assessment of flood control measures to protect the population in selected cities of the South Bohemian Region (the Lužnice basin)
CHLISTOVSKÝ, Miroslav
The Diploma thesis on the theme "Assessment of flood control measures to protect the population in selected communities of the South Bohemia region in the catchment area of the river Lužnice" is divided into theoretical part and the research part. The theoretical part is a general whole, which in the sections refers to the relevant legislation of the flood problems, it explains the flood as the concept and everything associated with it. In particular it introduces the readers with flood characteristics of the territory of the Czech Republic and with the characteristics of the catchment area of the river Lužnice. It describes the selected municipalities by its flow, which are the subject of the research. It explains the difference between a natural and an extraordinary flood, describes the historic and contemporary floods and their damage. It deals with the protection from natural disasters, characterizes the activities of the relevant organs of the protection flood. In the context of the protection of the population it defines the summary measures that help to ensure the protection of life and health of the people, property and environment in emergencies, which are warning, evacuation, hide and emergency survival of the population and other measures to ensure the protection of life, health and property. The aim of this work is to evaluate the effectiveness of flood control measures from the perspective of the number of the protected inhabitants on the territory. In order to achieve the goals, it was necessary to make several consecutive steps. On the basis of assessed results it could be returned to the research question, whether the built flood protection measures are effective in relation to the protected values of the life, health, property and the environment. For the fulfillment of the objectives of the work and verification of research questions,it was need to be familiar with the relevant legislation of the subject, then with the implemented measures, flood protection plans of the municipalities including analysis of their substantive and organisational components. After that to perform the qualitative processing of the survey, the respondents of which were the statutory representatives of the municipalities, who are in charge of the flood protection, and other charged people (e.g. crisis management staff, officers of the Department of the environment or Building office, etc.). The found facts served to the description, evaluation, comparison and analysis of the flood control measures in relation to the number of the protected inhabitants within the catchment area of the river Lužnice. In this way the concrete results were obtained and discussed in the comments of this Diploma thesis. The submitted Diploma thesis in its research part assesses the effectiveness of the flood control measures in the framework of the protection of the population in the South Bohemia municipalities - Bechyně, Tábor, Planá nad Lužnicí, Soběslav, Dráchov, Veselí nad Lužnicí by the flow of river Lužnice, that touches the ranked in the river kilometres from 10,6 to 77,3 km lines. The inspiration for the processing of this Diploma thesis there were the consequences of disastrous floods in 2002, 2006 and 2013 in these areas, which have caused enormous damage and even loss of life. Then the personal interest of the author, as a resident of the town Veselí nad Lužnicí and respectively the member of the crisis management of this town. The research question and the methodology of the research were designed to be filled the objectives of this thesis, it means the evaluation of the effectiveness of the flood control measures from the perspective of the number of the protected inhabitants on the territory. The thesis evaluated the current status of flood protection, description, comparison and analysis were made. There were designed some of the other possible measures that would, in my opinion, led to the improvement of flood protection...
