Phosphate conversion coatings
Ševčíková, Barbora ; Trčka,, Josef (referee) ; Zmrzlý, Martin (advisor)
The main objective of the master’s thesis is to study the influence of phosphate coating structure on the mechanical properties of screw connection. The theoretical part describes the conventional phosphating process and it is followed by an analysis of current knowledge of phosphating technology. Experiments are carried out on screw valves mounted to a high pressure diesel pump by Bosch Diesel s.r.o., made of unalloyed carbon steel. To investigate the effect of the structure on the connection sealing, twelve kinds of phosphate coatings varying in one process parameter were prepared. The monitored parameters determining the phosphate structure are – type of phosphate and activation bath, its temperature and concentration and time of immersion. The sealing connection is examined during simulated assembly process by angle controlled tightening while measuring torque and permanent material deformation. Prepared layers are characterized by determination of weight per unit area and their structure observed by electron microscope.

Impact of elevated carbon dioxide concentration on the Rubisco amount and activity.
Zachová, Lucie ; Babák, Libor (referee) ; Hrstka, Miroslav (advisor)
In this diploma work changes of initial and total activities and content of Rubisco in beech and Norway spruce were studied. The plants were cultivated in conditions with ambient CO2 concentration (350 mol·mol–1) and elevated CO2 concentration (700 mol·mol–1). Three series of samples (at the beginning, in the middle and at the end of growing season) were taken. Initial and total Rubisco activities were measured spectrophotometrically and activation state was calculated. Rubisco content was determined by SDS–PAGE method. Rubisco activity in beech cultivated in elevated CO2 concentration decreased during the whole growing season while in beech growing in ambient CO2 concentration Rubisco activity decreased up to middle of growing season and then increased. Rubisco content in beech in ambient CO2 concentration slightly increased and in beech in elevated CO2 concentration decreased up to middle of growing season and then increased. Rubisco activities in Norway spruce both in ambient and elevated CO2 concentration decreased. Rubisco content in Norway spruce in ambient CO2 concentration decreased but in Norway spruce in elevated CO2 concentration first decreased and then increased.

Activation admixtures in concrete
Eger, Lukáš ; Hela, Vlastimil (referee) ; Hela, Rudolf (advisor)
The aim of my bachelor´s work is the summarization and focus on admixure concrete,and the active and inert admixure, which have some positive characteristies for fresh and hardened concrete. Theoretically, I tried to study the increase of their joining potential while this characteristic can be used by either chemici or mechnical way, their combination as well. I also Works on evaluetion of physically mechanical influence for fresh and hardened concrete that can up to 60 days old while the cement was partly substituted by admixure of different character.

Container sewage treatment plants up to 500 PE
Krejsová, Věra ; Kaštanová, Barbora (referee) ; Hluštík, Petr (advisor)
The aim of this bachelor´s thesis was making a survey of companies involved in producing container type waste water treatment plants in the domestic market. In the first part of the bachelor´s thesis there is an overview of types of plants, including the method of implementation, use and placement and subsequent operation. In the practical part there is a list of companies active in this field in the Czech Republic that were compared to each other in terms of technological, machine-technological and financial aspects depending on the population for which they are intended for. Data provided by these companies and their processing can be used in selection of container of waste water for expert and unprofessional public, which is considering the acquisition of container plant.

Design processes in customer care and support
Müller, Vladimír ; Říhová, Zora (advisor) ; Roulová, Petra (referee)
The Diploma thesis is engaged in the modelling of business processes, focusing on their design. Especially processes in area of providing support and customer care. The main goal of the thesis is application modelling method for selected business processes in a particular company engaged in telecommunications services. The theoretical part is focused on processes, process management and standards for the business process modelling. In the practical part are then described selected processes related to ABC satellite television services. These processes are designed by selected methodology. Under the proposed processes that take place after activation are calculated costs of operation the process (financial, human resources). These costs are calculated to the time when it is expected to 200,000 customers of ABC satellite television. Summary of costs is in evaluating the proposal.

Income from operations -- the comparison of the Czech legislation with the US GAAP regulations
Horváth, Miroslav ; Randáková, Monika (advisor)
In my bachelor work called "Income from operations -- the comparison of the Czech legislation with the US GAAP regulations" I have focused on the question of reporting of the income from operations according to two different accounting systems. I have chosen the US GAAP because of their unique position in the world. There are notable differences between Czech and American income from operations, such as different view of recognition of the expenses and of the revenue. Very significant difference is also activation. It is related to the expenses classification used in Czech Republic. There is not such a concept in the American system. Another difference is in the form of income from operation. In Czech Republic it is fixed, while in USA it is not fixed and it is modified with reference to the significance of items. In our time of globalization, all of the systems influence each other and there is an intention of merging. Therefore it is important to take into consideration other systems, try to learn pluses and to include them into the Czech accounting system.
