The thesis deals with public participation in the process of assessment of environmental impacts EIA in the case of biogas stations in the Czech Republic. The theoretical part is focused on some issues, explanations of key concepts and contexts. In the practical part are analyzed specific plans in terms of public comments and taking them into account in the final statement. Everything is accompanied by the results of the survey.

My work assesses the technology use of corn silage extrusion for biogass production based on biological proces, technological limits, legislation and financial indicators of the biogass station. The theoretical part of the thesis is focused on the extrusion process. Based on the robust simulation of the experimental part we can conclude, that the pressure of 1.372 MPa probably moves close to the biotechnological optimum in the relation to the kinetics production of CH4 in certain conditions (the temperature of 38 °C, the delay time of the corn silage in the high pressure extruder CZ UV 21314 was 600 s). From the economic point of view, the assessment was carried out using the net present value (NPV), which serves as a criterion for evaluation of the profitability of investment projects. The technology seems to be a very interesting alternative not only for financial viability reasons, but also in relation to the environment.

Diploma work is based on technological, economic and legislative assesment of the problem of using bekary returns to propose alternative solution in relation to the processing technology of anaerobic fermentation. The participation of bakery returnts were laboratory simulated in automatic anaerobic fermenters called Stix. Teoretical part is focused on valid legislation. The economical assessment was evaluated by the index of the net present value. The highest production of methan was evaluated in propotion 100:0 of bakey returns and dung. Although the ideal proportion is 50:50 from economic assessment.

Many agricultural biogas stations process predominantly phytomass specifically grown for power engineering purposes as a primary raw material. This results in gradual increase of maize proportion in sowing sequences at the exclusion of traditional area-specific crops, which presents various potential negative effects. The aim of study is to evaluate the substitution of maize with wheat straw in the anaerobic fermentation process from the biotechnological and economic viewpoint. For this purpose, wheat straw pellets were pretreated using the high-pressure extruder in compliance with UV CZ 21314 at different runtime parameters. Cumulative methane (CH4) production in quarter-mode operation simulation, based on the extrusion pressure, cycle duration and fermentation temperature, was the main evaluation criteria. Optimal run time parameters were derived from the approximation ? extrusion pressure 1,35 MPa, reaction time 210 s, in order to achieve maximal CH4 production at mesophilic fermentation temperature (38 °C). For fermentation temperature 48 °C, optimal pressure 1,25 MPa and cycle duration 180 s were approximated. The discount rate of Net Present Value (NPV) was established as a main comparative criterion considering overall executive, legislative and technological aspects of analyzed biological effects. Based on these findings suggest, wheat straw extrusion is interesting, unconventional and profitable technology in the field of biogas production.

This work aimed to evaluate long-term changes of selected chemical and physical parameters of rainwater from their own rain gauge stations Stropnicko. Chemical and physical parameters influence the rate of loss of substance in the landscape through the soil environment. In particular, the amount and concentration of dissolved sulphates and nitrates, affecting the value of the current pH. Samples were taken from their own rain gauge stations Stropnicko. Names of stations from which samples were taken are Horní Stropnice, Nakolice, Paseky and Nové Hrady. Rainfall were measured between the years 2005-2011 and were subjected to chemical analysis.

In the master thesis the focus is laid on assessment of data and values from particular biogas generation units. For this topic I introduced in particular chapters of the thesis own opinions and experience of various experts. Expert data have been compared with own results gained by testing and evaluation of such received data. In this master thesis further technical parameters for the technology of anaerobic fermentation have been put together as well as information and data about other new technologies for biogas treatment and cleaning. Attention has been paid also to the outlook for using this environmentally friendly and green way of energy harvesting in the future.

This thesis on the "Establishing of a TV station in the digital era" describes and evaluates the influence of digital technologies and changing viewer behavior on television industry. It analyzes the Czech TV market regarding television operators, distribution technologies, the development of viewing shares and ad revenues and developing trends. The aim of this thesis is to show the status quo of the Czech TV market and to examine opportunities for the establishing of new television stations. Chapters of the first part focus on the current state of the Czech television market, main operators of TV stations, legislative, distribution platforms, assessment of ad revenues and the evaluation of research results. The second part of this thesis focuses on a case study on the establishment of a TV station.

This diploma theses analyzes issues in suggestions of ridding track, their conception and conditions of realisation. Thesis also deals with financial aspect of ridding track realisation. Suggestion of ridding track in Bohemian forest is dealt as a work frame based on feasibility study.

The objective of this thesis is to check the preciseness of the total station Leica TC(R) 407 ser. No.660021 by using the defined methods. The data collected through measurements and by the computation procedures according to the relevant standards and the proceedings described by the professional literature were compared with the data stated by the manufacturer. The accuracy of the telemeter and the goniometric part of the device was tested. The theoretical part of this thesis is focused on the basic measurement methods and distance determination, principle of the electronic direction measuring and the error theory. The practical part of the thesis is focused on checking the accuracy of the measured horizontal direction and the zenith angle, as well as checking the preciseness of the telemetric part of the device. As a result the standard deviations of the measured distances and directions have been determined.

The aim of this diploma thesis is reconstruction of an existing heat recuperative station. The reason is morally and physically survive to the device. Introduction to focus on the heat exchangers. The next section is devoted to the actual design of technological devices exchange stations, which represents the heat exchangers, pumps, control valves, safety devices, etc. The final phase is an economic analysis aimed at determining return on investment.
