Chip conveyor
Lukeš, Petr ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor's thesis focuses on the construction of a chip conveyor. The construction will be based on the information resulting from the conducted research. The thesis describes the importance of chip management in current production processes. During the research, the advantages and disadvantages of individual design solutions were evaluated. The portfolio was compared in the overview of manufacturers. After choosing the machining center and the machined material, a suitable type of conveyor was chosen. Finally, individual structural elements were selected and described. After performing the functional calculations, the chip conveyor was constructed. The output of the work is an assembly drawing and drawings of important structural parts.

Permanent Way in Tunnel
Kulhavá, Daniela ; Lukeš, Petr (referee) ; Svoboda, Richard (advisor)
The master thesis deals with the comparison of railway superstructure structures in a tunnel. It compares the construction of the ballast base and the slab track - specifically the type with concreted track length and the type with prefabricated slabs. Specifically, the slab track type Rheda 2000 and ÖBB-PORR are considered. Furthermore the construction and maintenance technology of these structures is proposed. A final comparison of the advantages and disadvantages of the different types in tunnel applications is made.

Mini hockey in the 4th grade category and its differences from regular hockey viewpoint of individual play moves.
Lukeš, Petr ; Šťastný, Petr (advisor) ; Arnošt, Pavel (referee)
Thesis title: Mini hockey in the 4th grade category and its differences from regular hockey viewpoint of individual play moves. Thesis objectives: To ascertain and compare the number of individual play moves in mini hockey and modern hockey in the 4th grade by way of indirect observation and audiovisual technology. Method: For data collection we used indirect observation via a videocamera. Data thus collected was processed, filled in to charts and compared. Results: Mini hockey players made 9x more successful shots (7x more on the wicket and 2x more outside of it), the rival team's goal-keeper sent forth 4x more shots and caught 3x more. Mini hockey players handed off accurately 2x more frequently and there were also 2x more inaccurate handoffs. They processed 2x more successful handoffs and further 3x more unsuccessful ones. In personal matches, mini hockey players won 2x more pucks. The players were able to break free by changing direction or speed 2x more often, as well as by doubling. Mini hockey players were 2x more frequently in contact with the puck than modern hockey players. Keywords: Mini hockey, regular hockey, 4th grade, individual play moves

Barriers to the Development of Wind Energy Use in the Czech Republic
Lukeš, Petr ; Sládek, Ivan (advisor) ; Voják, Karel (referee)
The development of the wind energy exploitation is a sum of processes which are subject to variety of heterogeneous factors. The nature and the leverage power of those factors vary and develop over time. Each regional or national location can be characterized by variety of factors, which are specific for respective locations. The wind energy development in the Czech Republic is influenced by number of barriers which restrain or slow down further progress. These barriers stem from environmental, economical, social and institutional disposition/nature of respective technologies. This thesis at first, based on available qualitative and quantitative data, describes and analyzes the situation and development of the wind energy exploitation. Specifics of the wind energy are placed in the context of selected European countries where factors and barriers influencing the development is described. The theme is regarded with spatio-temporal distribution of a "new technology". The thesis goes on focusing on identification of barriers that have impact on the wind energy development in the Czech Republic. Those restrictions/barriers are subsequently confronted with stands and perception of specific stakeholders, which are involved in the process. Analyses are carried out not only on individual barriers but also...

NO Synthases, TGF-beta 1 and EGF Expression in Patients with Proven Oropharyngeal Helicobacter Pylori Infection and its Role in Oropharyngeal Pathogenesis
Lukeš, Petr ; Astl, Jaromír (advisor) ; Šlapák, Ivo (referee) ; Fučíková, Terezie (referee)
The thesis focuses on detection of Helicobacter pylori (HP) in the oropharyngeal lymphatic tissue and changes of selected cytokines expression according to the inflammatory response to the HP infection. HP is well known gastric pathogen, which leads to the development of chronic gastritis, gastric ulcers and malignancies such as gastric carcinoma or MALT lymphoma. According to the supposed way of transmission of this bacterium, oral cavity was investigated for HP presence recently. Data about possible colonisation of oropharyngeal tissue are insufficient. Several papers were published with inconsistent results. This inconsistency is due to different investigation methods used. The pathogenetic effect of HP in the oropharyngeal tissue was not investigated. It is supposed, that HP could lead to inflammation or carcinogenesis of oropharyngeal tissue in the same way as in gastric mucosa. The presence of HP in oropharyngeal tissue samples of patients suffering from tonsillar carcinoma, chronic tonsillitis or obstructive sleep apnea syndrome (OSAS) was investigated in this study. Real-time PCR was used. Part of the patients was investigated for gastric HP presence using UBT and PCR. Specific anti-HP antibodies and levels of EGF and TGF-beta 1 were detected in sera. Differences in iNOS, eNOS and caspase-3 were...
