Biogenní aminy v hroznech révy vinné a ve víně
Veverka, Jaromír
The aim of this work was the determination of selected biogenic amines in selected varieties vine fruit. The literature review describes the characteristics of biogenic amines, their creation, It is specified formation of biogenic amines individual microbiological agents and their health effects on the human organism. Then work characterized the winemaking process, and possible effects creation and content of biogenic amines in its manufacture. Custom work is divided into several parts Were monitored randomly collected samples of wines from around the Moravian region and analyzed the contents of biogenic amines. During alcoholic fermentation, malolacical fermentation and purification process was monitored training and development of these substances. Was observed dynamics of biogenic amines during fermentation and BA were determined after malolactical fermentation . Investigate the possibility of elimination of biogenic amines in wine clarification - were studied reduction of biogenic amines using standard fining agents (bentonite, gelatin, PVPP, Tosil). Watch biogenic amines (histamine, tyrosine, tryptamine, cadaverine, spermidine, spermine and putrescine) will be analyzed in a sample of chromatographic separation and quantified by comparison with standards.

Disintegration of sludge thickened by flotation
Veverka, Jakub ; Jecha, David (referee) ; Houdková, Lucie (advisor)
The main topic of this thesis is a research of influence of disintegration of sewage sludge on the production of biogas during the process of anaerobic fermentation. The theoretical part deals with issues and specific methods used during the process of waste water cleaning, furthermore it contains simplified description of waste water treatment plants and particular devices. The number of ways of processing sewage sludge and its potential utilization id also discussed. Following parts of the thesis analyze in detail my own process of anaerobic fermentation including important factors influencing this process. Comparison of aerobic and anaerobic fermentation and ecological perspective on the issue are included in this part. Another important part of the thesis deals with disintegration and description of the disintegration methods and devices. The fundamental part implies the analysis of the executed experiments. Experiments analyze the growth of biogas during anaerobic fermentation depending on the disintegration of sewage sludge. After that the evaluation of the experiments is stated together with economical calculations of the disintegration process executed in laboratory conditions.

Manipulator of fruit products
Riesner, Tomáš ; Veverka, Josef (referee) ; Kašpárek, Jaroslav (advisor)
The work deals with construction project of manipulator for loading of fruit products to a means of haulage (lorry semi-trailers, railway wagons). One part of the writnig is an idea concept of whole machinery and a detailed project of a lifting part with its strentght calculation. That was firstly worked out manually as a design and then subsequently optimalised by the Finite Element Method. Design documentation was made up based on the construction project and the calculated values.

Domestic heat pump
Veverka, Jakub ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
The aim of the Bachelor's thesis is the ,,Heat pumps and house heating " . The thesis is divided into four main parts. The first part briefly describes the principle of operation and the types of heat pumps (The variants are water to water, air to water, earth to water), including the advantages and disadvantages of their use. Heat pumps are effective solutions to home and hot water heating. The part describes the heat transfer between the condenser and the heating pipes. The second part includes a proposal for using the specific heat pump, a brief description of the selected object and calculate the heat loss. The third part pays attention to calculating the energy performance of buildings. Economic evaluation of the selected system and financial returns are contained in the fourth part of this work.

House in Letovice
Veverka, Jiří ; Hofman, Petr (referee) ; Müller, Jan (advisor)
This work deals with the design of a newly-built single-family house, which is located in the cadastral area of the town of Letovice. It is a two-floor house without a basement, which is designed for a family of five. The house is detached. The vertical loadbearing structures are lined with sand-lime block SENDWIX, insulated by contact thermal insulation system from polystyrene plates. The building is covered with a gable roof with a slope of 40° a gable dormer window on the south side and with an elongated part of the roof above the garage with a slope of 18°.

The Analysis of the Relationship between Inflation and Unemployment in the UK in the Second Half of the 20th Century
Veverka, Jaroslav ; Mirvald, Michal (advisor) ; Rod, Aleš (referee)
The main goal of this thesis is to analyse the mutual relationship between the inflation rate and the rate of unemployment in the United Kingdom on quarterly based data 1962-1967. At first this thesis introduces papers and empirical studies of some important authors who formed the concept of Phillips curve. Furthermore, there are described also studies which criticize this macroeconomic concept. Within the regression analysis is researched the mutual relationship with aid of the linear, hyperbolical and the logarithmic regression model. The result of this thesis has confirmed the mutual inverse relationship between the inflation rate and the rate of unemployment in the analysed period of time which implies the existence of the Samuelson-Solow modification of the Phillips curve in the United Kingdom in 1962-1967.
