The racionalization of machining of gearboxes
Sádlo, Dominik ; Růžička, Petr (referee) ; Sliwková, Petra (advisor)
Content of the thesis is the proposal of new technology using machining centres, including five controlled axis. Benefit of implementation the new nechnology is investigated at machining example, which is the gear housing of a single stage gearbox, manufactured in the company. In the first part of the thesis, the general properties of gearboxes and their housings are analyzed, as well as the procedure of the current proces of the machining representative. In practical part of the thesis is proposed necessary tool equipment and jig equipment, needed for machining of the part. After that are analyzed and filled in time studies, provided by manufacturers of machining centres. On the bases of these studies, were calculated operating times and operating costs per one piece of the housing. In the part of technical and economical evaluation is calculated the return of initial investment, including costs for byuing new machining cente and cutting tools equipment. Finaly are evaluated the overal benefits of the new technology, given the needs of the company.
Traditional working and quality of timber during repairs of timber structures
Kloiber, Michal ; Růžička, Petr
Extensive field experience with repairing timber structures shows two main limiting factors for the quality of work that are often circumvented or simplified. First, it is the quality of the timber for the repairs (replacements, additions) and the resulting problem when the recommended criteria for the selection of suitable material are not met, with regard to the long-term coexistence of the new timber with the original material. Second, a critical factor is the way in which the timber is worked - the preferred traditional working is for various reasons replaced by counterfeits. Due to the limited scope of this paper, we can only pay attention to the most blatant case, which is working of logs by hewing.
Survey report: Construction and technical assessment of the state of timber, trace analysis and surveying of a timbered barn in Skalička 3
Kloiber, Michal ; Růžička, Petr ; Buzek, Jaroslav ; Hrivnák, Jaroslav ; Bláha, Jiří
Surveys whose aggregate output is this survey report included the determination of the extent of damage to the timber, surveying, and trace analysis of the original craftsman working of a timbered barn belonging to house no. 3 in the village of Skalička u Hranic, which is located in the Přerov district in the Moravian region called Pobečví. The report has been drawn in response to the demand by the Wallachian Open Air Museum located in Rožnov pod Radhoštěm, which contained a request to diagnose the timber elements using NDT devices and carry out their trace analysis. The findings will contribute to a qualified assessment and proposal of a harmless transfer of this unique timbered building.

Preparation of constructs for overexpression and crystallisation of prohibitin complex from \kur{T.brucei}
RŮŽIČKA, Petr
Aim of this work was to prepare plasmids for overexpression of prohibitin complex from T. brucei. To overexpress this protein complex full and truncated versions of two prohibitin genes were cloned into RSFDuet-1. These constructs will be used to overexpress prohibitin complex and subsequently to resolve its crystal structure
