Analýza současné energetického postavení Evropy v návaznosti na celosvětovou situaci v těžbě a dodávkách zemního plynu a posouzení rizika závislosti celého regionu na třetích zemích, především na Rusku. Popis procesů, které v současnosti probíhají v evropském plynárenství. Jde především o snahu diverzifikovat evropské zdroje zemního plynu do budoucna a zajistit si tak bezpečnost dodávek, tak aby byla uspokojena jeho vzrůstající spotřeba.

The thesis builds on previous work comparing biodiversity of small terrestrial mammals at four localities with different management. The thesis significantly extends the previous work. The theoretical part consists of a literature search on the issue of the occurrence of small mammals in an area around the town Třeboň, their microhabitat preferences and the impact of farming on biodiversity of their communities. The practical part describes the species composition of small terrestrial mammals? communities and changes of their abundance and biomass during the three growing seasons, depending on the climatic characteristics of the locality. It includes evaluation of the results of the regular catches in traps (CMR method), which were realized from June to September between 2009 and 2011 (three catches once a year) at four sites with different management: Mokré louky - non mowed, Mokré louky - mowed, Cirkvičný meadow and a pasture (meadow) Jeţek. A total there were 553 individuals of small terrestrial mammals caught and we noted nine species: Microtus arvalis, Microtus. agrestis, Micromys minutus, Apodemus sylvaticus, Sorex araneus, Sorex minutus, Neomys anomalus, Neomys fodiens, Crocidura suaveolens and Apodemus sylvaticus. Various characters of biotopes provide differently suitable conditions for the establishment of populations according to their habitat requirements. The predominant species in Mokré louky mowed and non-mowed was Microtus agrestis and in the Cirkvičný meadow and Jeţek it was Microtus arvalis. The highest abundance and diversity were recorded in Mokré louky mowed and non-mowed. The highest biomass was recorded in 2009 and 2010 in summer, when temperatures were highest. In 2011, there was the highest biomass in the spring, probably because the previous winter was very warm. The highest Simpson's index of species diversity was in Mokré louky mowed in 2010. The relative abundance was highest of Microtus agrestis, Apodemus sylvaticus and Sorex araneus, alternately in Mokré louky mowed and non-mowed. Microtus arvalis had the highest abundance for all three years in the Cirkvičný meadow. The probability of capture during capture was always increasing, reaching 100%, as in the Microtus arvalis, Microtus agrestis, as well Apodemus sylvaticus. The highest probability of re-capture was at Apodemus sylvaticus, where 33% of the second day and 43% of the third day. The results presented in the thesis contributed to the project NPV 2B06023 MŠMT.

The main target of my diploma thesis was the comparison of wolfspider fauna on cattle and sheep grazing pastures. For this reason I laid pitfall traps at these pastures during three months of 2017. I collected pitffall traps every month. Totally I got 90 samples. 3418 spiders were caught in total, from this 1164 individuals belonged to wolfspiders. I determinated all adults wolfspiders and sorted them into 6 species. Ammount of spiders and wolspiders of course varied during the time of study. The most abundant month was May (2532 spiders, 876 of wolfspiders), the number of caught spiders was decreasing rapidly in following months. The most numerous wolfspider spieces was Pardosa palustris (77 % of all wolfspiders). No red list or rare species of wolfspider was caught. Results of study prove that abundance or species diversity of wolfspiders isn´t influenced by species of grazing animal. But intensity of grazing has influence on species diversity and abundance of wolfspiders and spiders generally. Both indicators are decreasing with increas of grazing intensity.

This master thesis deals with issue of natural gas liquefaction, its transport, storing and regasification. Part of this work was designing off a small liquefaction cycle and regasification unit.

This Thesis is titled ?qThe availibility of support from the European Union energy saving in the trafic in South Bohemia region??. It is focuses on the situation in transport in the European Union and the Czech Republic. The transport strategy for next year is to use different types of alternative fuels. This Thesis will describe the possibility of taking the financial subsidies to promote the alternative sources of transport in the European Union, or other sources.

The dissertation with the topic Ground as an Energy Source discusses the utilisation of horizontal heat exchangers as sources of heat at low temperature for heat pumps. Chapter Current Situation in the Field describes the environmental properties of heat pumps, the effects existing in the ground and the individual types of ground heat exchangers. Chapter Objectives and Hypotheses of the Dissertation lays down the individual hypotheses of the research and the objectives of the dissertation. The theoretical part of the Set of Methods chapter gives an understanding of the mathematical relationships describing the theory of heat sharing in the ground, the measurement methods, the method of processing experimental data, and the measuring instruments used. The Results and Discussion chapter includes the basic findings and opinions processed on the basis of values measured. The final chapter Conclusions and Recommendations for Practical Use comments on the results achieved and elaborates on utilising horizontal heat exchangers in practice.
