Monitoring of 0+ juvenile fish communities was realized in years 2012 and 2013 in 39 localities in 25 selected Moravian rivers. It was realized in collaboration with Povodí Moravy SOE research workers. The aim of this diploma thesis was to conduct a survey of 0+ juvenile fish communities and evaluate basic attributes of these ichthyocenosis (species richness, biodiversity, equitability, abundance and domiance). Secondary aim was the evalutation od hydromorphological conditions and water quality based on data provided by Povodí Moravy SOE. This monitoring was realized using the mobile FEG 1500 electrofishing device. The electrofishing crew moved upstream using continuous fishing strategy. Each locality was selected by highly experienced research workers of Povodí Moravy SOE. Caught fish were determined immediately and carefully retruned to the stream. In total there was present 28 0+ juvenile fish species. The most frequent was chub (Leuciscus cephalus, 23 localities), gudgeon (Gobio gobio, 19 localities) and roach (Rutilus rutilus, 19 localities). In 13 localities occured the fish fry of barbel (Barbus barbus) wich is positive surprise due to its sensitivity to water pollution. In contrast the massive presence of round goby (Neogobius melanostomus) in some localities was an unpleasant finding. 4 localities were without fish fry. This survey has observed increasing trend of biodiversity depending on improving of hydromorphological status while the abundance showed almost no diference. Saprobic index of 0+ juvenilie fish community increased with deteriorating of water quality which could mean that the fish fry is relatively reliable indicator of water quality. The results of this diploma thesis could be used in documenting of Moravian streams and in comparisson with another monitorings in these localities.

Revitalization generally are activities leading to the recovery of ecosystems in the landscape and their stabilization.

There are two nuclear power plants in the Czech Republic for which measures to protect the population are proposed in the case of a radiation accident. This diploma thesis deals with one of them by decontamination of persons and techniques in the emergency planning zone. The theoretical part of the diploma thesis focuses mainly on knowledge and concepts in the field of ionizing radiation, radiation protection and emergency planning. The main objective was to analyze, compare and evaluate the existing and newly introduced decontamination means of persons and equipment of the Fire Rescue Service of the Czech Republic and the Army of the Czech Republic. For this purpose, eight decontamination devices have been selected for use in a radiation accident. One of the partial objectives is also to compare the decontamination methods and procedures of both components. The quantitative processing of the parameters studied was used to compare, and a multi-criteria decision-making method was used to obtain the results, using the scoring method. In order to obtain data and information, searches of available publications, methodological sheets and instructions for decontamination equipment were carried out. All information has been consulted with chemical experts from the Fire Brigade of the Czech Republic and chemical units of the Army of the Czech Republic. The results of the comparison showed that the decontamination facilities of the members of the Fire Rescue Service of the Czech Republic are more suitable for use in the radiation accident. Their main advantages are a more effective solution for wound decontamination and a system for capturing and collecting contaminated water. However, the Army of the Czech Republic would be able to do the same work after the partial modifications. The decontamination equipment for solving the radiation accident is constantly being refined. An example is the Portable Frame Gamma Detector. This allows you to speed up the decontamination process and saves the forces and resources deployed to deal with an emergency.

Sand-pits which were formed especially in the floodplain of the Lužnice River since the 1950s currently constitute important landscape element of the Třeboň Basin. My diploma thesis is focused on the assessment of the impact of land use on the former sand-pits in the region of Veselí nad Lužnicí. Field investigations were carried out from the beginning of June till the end of August 2008. I mapped the land use of this area by using a map key. I put down particular areas {--} agricultural areas, forest areas, water areas, bild-up areas, other areas {--} into map photographs. The total area of the mapped territory was 989 hecteres. The biggest part of the area comprises of forest growths and field-grown plants. Water areas (with the main element of the mapped area {--} a system of former sandpits) formed 23% of the total area. On the bank sof the sand-pits were placed phytosociological relevé, which illustrated littoral vegetation and environment in which this vegetation is located, and what is the influence of human activity on vegetation. I placed 74 phytosociological relevé in this system. I recorded 125 plant species {--} out of these were 104 herb plants and 21 woody species. I recorded 41 nitrophilous, 52 wetland, 16 ruderal and 2 stronngly endangered species. Altogether, 20 water samplings were carried out. Horusice I sand-pit is the richest in nutrient, the poorest in nutrients is Horusice sand-pit.

The amount of data obtained by barcoding of prokaryotic 16S rDNA from natural habitats is increasing exponentially. Thus, methods enabling us to extract useful information from these data are of increasing importance. In this thesis microbial communities from water, sludge and drilling dust were analyzed by 16S rDNA sequencing in three geologically well described sedimentary aquifers in Bohemian Massif. The main goal of this research was to establish how different analytical approaches can be useful in interpretation of groundwater biogeochemical processes. Three approaches were used: First, taxonomy and metabolic traits of the most abundant microorganisms were assessed. Second, ordination methods showing metabolic and taxonomic variability between communities were used. Last the analysis of phylogenetic dissimilarity using UniFrac metrics was performed. When analyzing individual localities separately, the shift in microbial community composition corresponds with the change of environmental conditions. The unconstrained ordination method based on the variability in metabolic traits indicated, that sludge samples are more informative than water samples when asking which electron donor is used in microbial communities. On the other hand, unconstrained ordination methods were useless when the...

In my master thesis I deal with the issue of the identity of 19th century Russian society and the role of the Volga River in it. I focus on the characterization of Russian identity in the broadest sense, on the relationship of human society to nature, and on two case studies from the Upper Volga region. In the theory of Russian identity I consider four of its characteristic features - ambivalence, patriotism, spirituality and sentimentalism - to be crucial. The analysis of the relationship between human society and nature includes a section devoted to the reasons for human attachment to landscape, discusses the concept of national landscapes, and presents the dominant idea of the Russian landscape at the end of the 19th century. The last section is devoted to research on the role of the Volga River in the self-identification of the inhabitants of the Upper Volga region. In a study of the worship of the source of the Volga and in research on folklore, I note the attitude of various influences towards this river and, on this basis, define the place of the Volga River in the life of different social classes. The conclusion of my study is that the role of the Volga River in the life of the Upper Volga inhabitants was in many ways the same as its role in the national social discourse, but quite out of...

The aim of this diploma thesis is to point out European Union´s goals such as low carbon economy, mainly future increasing the use of renewable sources as a potential source of energy. Slovak republic has due to its position in central Europe, rich in natural healing sources of water, which are considered as the most perspective sources of renewable energy in this country. The problem was solved as energy, economic and environmental analysis of Balneotherapy at Slovak Heath Spa Piešťany a.s. This analyzation was provided by real experimental measurement of temperature and flow rate and computational simulation of technological devices in opened natural healing water system. Experimentally measured data were afterwards use for elaboration conceptual design of new technological devices in order to increase efficiency of collection energy from potential renewable source of energy. The research shows that with help of new design technological devices connected to existing ones will be possible to cool down temperature of hot natural healing water from 67 °C to 21 °C, which decrease operation costs of Balneotherapy for more than 1 414 € per day. By Slovak republic entering to European Union it was necessary to accept global goals of low carbon economy. This diploma thesis provides an attention on potential energy in natural healing sources of water as renewable source of energy and helps Slovak Health Spa Piešťany to decrease amount of green-house gases released to atmosphere by efficient increasing the use of energy potential in natural healing source of water.
