Forsteite and the Possibilities of its Synthesis
Nguyen, Martin ; Keršnerová, Lucie (referee) ; Sokolář, Radomír (advisor)
The aim of this Bachelor thesis is to characterize the most important properties of forsterite and its practical use. Theoretical part contains characteristics of individual raw materials, which are used for synthesis of forsterite and the assessment of raw material possibilities of Czech Republic for the production of forsterite. The main focus is placed on the detailed research of published results of the most used technologies for synthesis of forsterite. At the end of theoretical part is the design of the most suitable production technology for forsterite in the Czech Republic. The practical part verifies suggested design of the production technology for forsterite synthesis together with a comparison of basic parameters of laboratory prepared forsterite with published parameters. X-ray diffraction analysis will be used for the evaluation of purity of the synthesized forsterite.

Contemporary technology of clay bricks production - possibilities and perspectives
Polláková, Lenka ; Pavelka, Oldřich (referee) ; Sokolář, Radomír (advisor)
In the theoretical part, this diploma thesis deals with brick production, basic raw materials for brick production and the technological process of production itself. It also focuses directly on the fired brick, its legislative requirements and manufacturers who currently produce this brick in the Czech Republic and Slovakia. The possibilities of current manufacturers are assessed in the practical part, especially in terms of salinity, mineralogical composition and behavior during firing of their production mixtures. As last the optimal firing temperature of the available mixtures is designed to achieve ideal parameters as frost resistence, strenght, appearance etc.

Pivovarské technologie v ČR a ve světě
Hambálková, Pavlína
The bachelor's thesis focuses on beer production technology in the Czech Republic and around the world. It is divided into theoretical and practical parts. The theoretical part describes the history of beer from its origins to the present day. The production technology is elaborated, including the raw materials and processes used. It particularly focuses on the phenomenon of Czech beer, its characteristics and uniqueness compared to other products. The practical part presents data from sensory and analytical measurements of selected bottom-fermented beers. The aim of the thesis was to analyze the literature and compare the quality of Czech lagers with a group of foreign beers. The highest rating in sensory analysis was awarded to Pilsner Urquell, which had the most points in all selected parameters, positively correlating with the quality of raw materials and production technology of this beer and the popularity of Czech lagers in our country.

Comparison of selected quality indicators of beers produced by different technologies
BUDÍN, Dominik
The bachelor thesis deals with the comparison of selected qualitative indicators beers produced by different technologies. The practical part is focused on the comparison of ten top-fermented beers from different industrial breweries, microbreweries and home breweries production. The individual beer samples were sensory assessed on the basis of subjective evaluation among ten evaluators. Respondents rated the following using a questionnaire bitterness, drinkability, aroma, flavour intensity and overall impression of the sample. At the answers of the respondents, graphs were drawn up and then evaluated and described verbally. In the research part of the bachelor thesis it was found by qualitative research, which top-fermented beers are preferred by men and conversely, which beers are preferred by women.

The impacts of battery electric vehicles production on material use
Pěnkavová, Markéta ; Ščasný, Milan (advisor) ; Janda, Karel (referee)
The main objective of this thesis is to estimate the material impact of the BEV production with the main focus on the BEV battery material demand. This is done using the life cycle analysis (LCA) along with detailed analysis of the battery material demand which is then linked to dynamic computable general equilibrium (CGE) model. The hybrid form of a fully dynamic CGE model is used to estimate the vehicle stock and annual new registrations for five different vehicle technologies (BEV, PHEV, Petrol, Diesel, CNG) in 2015 to 2050 in the Czech republic. These estimates are done for the business as usual scenario and then six different policy scenarios. The effects of direct government subsidy on BEV purchase are modelled along with the impacts of increase in ICEV registration tax, mineral oil tax surge or an expansion in charging stations market. Consequently, the results from CGE modelling are combined with LCA as the detailed BEV battery material composition data are used to estimate the material impact of increased BEV usage. The results from CGE modelling show a clear increasing trend in BEV usage in the future years for the baseline scenario, in addition, the modelled government scenarios incentivizing the BEV usage were shown to have a pos- sitive effect on BEV sales in the Czech republic while...

Ohrožení ekonomických zájmů EU v Jižní a Střední Americe.
Frýda, Jiří ; Opatrný, Josef (advisor) ; Kovář, Martin (referee) ; Barteček, Ivo (referee)
The dissertation analyses the threats to economic interests of EU in Latin America - mostly focused on MERCOSUR's countries. Both regions share history, cultural and social bonds which were interrupted by the Cold War. During this period was Latin America a natural zone of interest of the United States (similarity with East Europe and USS R). The fundamental event is the end of bipolarity. The dissertation is mostly focused on one decade between 2003-2013. The three main chapters define the concept of economic security, the relationship between the EU-Latin America on the background of the historical insight and third main chapter analyses China's engagement in Latin America. In the post-Cold War period came a significant paradigmatic shift in the perception of economic security/vulnerability. Considering the asymmetry of relations between the two regions, we analyze a historical background, including the so-called "shared values" that partially (but not entirely) can be challenged. Relations between the two regions are viewed as highly pragmatic with a strong emphasis on trade ties. China as a new element in the region, where traditionally has competed the United States and Europe, is the core topic of the main third chapter. Latin America isn't perceived as a single region, but it is consider in...

Transformation of geopolitical importance of Arctic Ocean due to climate change.
Doboš, Bohumil ; Romancov, Michael (advisor) ; Plechanovová, Běla (referee)
Work describes and predicts future development in geopolitical situation in the region of the Arctic Ocean. Problematic is covered with regard to melting of the Arctic iceberg leading to access of mineral resources under the sea floor, as well as to opening of so-called Northern Route as the shortest sea route between Far East and European markets. Thesis is a case study, which creates the most probable development in the region and its conflict potential based on study of available sources. Specific points covered in the text are, after geographically limiting the area and summing up the historical process, problematic of peak oil and sketching probability of melting of the Arctic iceberg. Second part covers the question of recovering of the mineral resources in the area - oil and natural gas as the most important. It also deals with dependence of the countries in the area on the drilling and with impacts of the possible drilling in the Arctic Ocean on the situation inside these countries. Last topic covered in this part are tools a conventions of the sea law dealing with setting of so-called Exclusive economic zones and technical difficulties of the mining process. Third part covers topic of availability of Northern Route and North-west Passage and their fallout on the trade between Far East and Europe...
