The diploma thesis is focused on the combustion of the low calorific gaseous fuels. The first part is devoted to the characterization and usage of low calorific fuels. Then combustion theory focused mainly on emissions and thermodynamics. Next characterization of burners and their modifications for low calorific value fuels is described. Safe storage and handling of chosen gases is also included in the last chapter of the theoretical part. Practical part includes the description of the laboratory experiment, which was a part of this thesis. It consists of the experiment description, experimental plan, calculation and evaluation of emissions, high and low heating value, density, flame temperatures and heat flux. Laboratory experiment was carried out with different fuels. Low calorific fuels were simulated by gradual increase of the concentration of inert gasses in the natural gas. Increased concentration of inert gasses had positive effect on the emissions. Measurement of the flame temperatures confirmed that the decrease of emissions corresponds to the inert gas addition to the noble fuel. Heat flux and thermal efficiency of the combustion was almost identical for each configuration.

This thesis is oriented on use of nature in art education. It consists of teortical and practial part. Theoretcial part describes possibiliteis of using nature and natural materials in art education in relationship with environmental education, history of art and art education in relationship with nature as inspiration or source of material. Practical part consits of two guidelines. The first one is focused on work with natural materials directly in nature. The second one is sectioned into another four guidelines inspirated by seasons of the year. Intention of this thesis is to point to the value of the nature in art education and offer number of possibiliteis how to use this topic. The main asset of this thesis is in summarizing knowledge about nature in relationship to art education and suggestions for activities inspirated by nature or realized directly in nature.

This diploma thesis deals with the history and the development of the gas industry in Czechoslovakia, namely the construction of the transit gas pipeline and development of the gas transit system. One of the part of this thesis is a history of the coal gas and the reasons for its gradual replacement by a natural gas. The metodology of this thesis is based mainly on interviews based on the method of oral history, on archival records, and contemporary literature. Primarily it is focused on oral history fieldwork, particularly on the personal experiences of narrators who were direct participants in the construction. This work is also focused on the circumstances of the negotiations of the construction of a transit gas pipeline and further expansion of the transit system from the seventies to the nineties of the 20th century. Keywords Transit pipeline, natural gas, gas industry, economy, energetics, coal gas, normalization

The master thesis analyzes the natural gas policy of Hungary in light of the duality in its international context. Hungarian decisions regarding energy policy are directly influenced by the EU through the country's membership and subscription to the Union's multilateral framework, but are simultaneously affected by the bilateral relationship with the key supplier of natural gas, Russia. This duality is analyzed as embodied in two natural gas pipelines projects, Nabucco and South Steam, both including Hungary as a transit country, but serving different interests. The study finds that the multilaterally defined community interests - although of increasing importance - do not prevail over bilaterally articulated interests with Russia in the field of energy.

The subject of my thesis is the exploration the landslide, landslide stabilization, design foundation and construct buildings in Brno Bystrc. Attention will be given to slopes safety factor and especially to design four-floor building construction.

Epigeic beetle communities were studied on three agroecosystems with different crops grown. All three agroecosystems were located in the vicinity of Ceske Budejovice (Lišov). The first eco-agroecosystem was alfalfa field. On the second one was meadow. The third eco-agroecosystem was permanent grassland. The agroekosystems differd not only in crops but also in agrotechnical operations during the capture. For all agroecosystems was for capture of the organisms used method of pitfall traps. Subsequently, those organisms have been studied. Then was studied the measure of human impact on the biodiversity of species of different ecological groups found in these locations.

This thesis on the topic of Technology verification in the field of wheel excavators and its excavations in the first general part deals with the analysis of the work carried out on the construction site. Wheel excavator analysis tools have been developed and used. The study included ?wheel excavators and the technical parameters and analysis with the binding on the size category of wheel excavators?. The second part of the work deals with the evaluation of the results of the data collection for the determination of the actual times of working wheel excavators; and resultant cycles, depending on the work carried out. In addition, there are factors that affect the intended performance wheel excavators and how it works in the implementation of specific operations. Part of the work is the determination of the values of the correction coefficients for the calculation of the actual performance and the determination of the actual wheel excavators, and subsequent analysis of the excavators? performance dependent upon carried out working operations. In conclusion, on the results gained from the analytical process, proposals and guidelines for the optimal use of wheel excavators within the construction industry have been attained.

In my diploma work I engage in the mechanization for the regular maintenance of building for the wateragricultural meliorations of piece of lands. The applicable mechanization: Dampr, Skrejpr, Dozer, graftmachine, bushescut{\dots}{\dots}{\dots}{\dots}{\dots} My proper work I engage on revitalization of pond names Hamerníků Doubí near by the village Lásenice. Out of the results of my proper work is evident, that the revitalization of ponds is very exacting and expensive work.

The main objective of my thesis was to project a design of a concrete chosen section of the cycling trail in the vicinity of the village of Kamenný Újezd, which is located in Southern Bohemia, south-west of České Budějovice. I propose two alternative cycling trails in accordance with the applicable standards, laws and technical conditions. A better alternative in terms of transport, economy, ecology and aesthetics, I elaborated to the phase of documentation for the notification of the construction of road according to Decree 104/1997 Sb.. In the project, I propose a direction solution, vertical solutions, width layout, road construction, earthworks, drainage, equipment and traffic signs. I analyzed property relations in the proposed cycling route and existing bicycle trails in the given locality. I suggested a cycling communication, which is multifunctional, therefore not only used by cyclists but also pedestrians, in-line skaters, and when appropriate, for occasional agricultural transport.

The goal of this master thesis is to analyse the potential of LNG for the Central European region with the emphasis on the strategic role of LNG imports in strengthening the energy security of the region and its possible role in replacing the traditional fuels in the transport sector of the Visegrad Group countries. The increasing availability of LNG, together with the predictions of its rapidly growing global supply in the following years, offers a window of opportunity for the Central European states. Particularly when it comes to their energy security, as the growing access to LNG supplies translates into a growing competition for the existing pipeline supplies from Russia. Furthermore, the thesis also focuses on the potential of LNG as an alternative fuel in the inland waterway and heavy duty road transportation of the Visegrad Group countries and the steps that these countries take to integrate LNG fuel in their transport sector.
