Maintenance work design for small transport aircraft
Bednář, Ondřej ; Koštial, Rostislav (referee) ; Třetina, Karel (advisor)
The aim of this thesis is to design maintenance work for a small transport aircraft. This thesis is focused on an overview of the activities, which are carried out in the maintenance of small transport aircraft with a capacity about fifty passengers. The first part of this thesis is conceived as a theoretical part and summarizes the activities used during maintenance - maintenance methods, a typical part failures, diagnostics, network analysis and equations for the calculating of the cost of maintenance. At the beginning are showed the basic characteristics of selected representatives of this category and regulatory requirements on them. The design of maintenance work is in the second half of the thesis. It includes the visualization of the database that could be used for the maintenance of aircraft and which could be subsequently evaluated. This is a general description of the maintenance work, which ca be performed during the pre-flight inspection, re-inspection for repeated flights, preliminary preparation and periodic maintenance.

The design of clamping equipment for tensile testing of car door hinges
Daněk, Jiří ; Čípek, Pavel (referee) ; Klapka, Milan (advisor)
This thesis deals with the problem of clamping fixture for tensile tests of car door hinges. The aim of the thesis was to design a new preparation that will replace the current one that is not satisfactory. All the goals of the thesis were met, the output of the thesis is a design of a product that meets the requirements of the standards and the customer. On the basis of the control calculations, drawing documentation was created and then Edscha had the new product manufactured. The product has been in operation for more than half a year and meets all requirements.

Aminoclays - optimization of preparation and characterization
Plotěná, Michaela ; Sedláček, Petr (referee) ; Pekař, Miloslav (advisor)
The objektive of this paper is to give an overview of synthetis, properities and application of magnesium phyllosilicate with 3-aminopropyl functional groups (aminoclay). The research in this paper focuses on preparing aminoclay, specifically to prove the prescribed procedure and its modifications. The structure of the final product was verified by X-ray analysis and scanning electron microscope. The main motivation is the synthesis of aminoclay opportunities in the pharmaceutical industry. Aminoclay would serve as an adsorbent that would ensure greater bioavailability of the drug.

Polymeric nanocomposites - preparation methods
Černý, Miroslav ; Žídek, Jan (referee) ; Kučera, František (advisor)
Literature search of bachelor thesis was focused to methods of CaCO3 nanoparticles preparation, surface modification and PS/CaCO3 nanocomposites processing. Experimental part was based on two methods of PS/CaCO3 nanocomposites preparation: emulsion and bulk technique of styrene radical polymerization in presence of CaCO3 and by compounding CaCO3 with PS in Brabender mixer at 220 °C. Prepared samples were observed using electron microscope.

Preparation and Characterization of Biochar - the Effect of Pyrolysis Conditions and the Source of Used Biomass
Novotný, Maximilián ; Pořízka, Jaromír (referee) ; Kalina, Michal (advisor)
This diploma thesis is focused on preparation of biochar samples, which were characterized to reveal influence of preparation conditions on biochar properties physical-chemical properties. Preparation conditions covered temperature range of 400 °C to 700 °C and 2 different residence times were used. Biochars from each source biomass has its own characteristics, however the similiarities between biochars from different sources were found. Biochar yields were specified and the minimum yield was at least 24 %. Analysis on content revealed, that oat brans, mixed wood and corn residue contain a lot of organic matter, relatively, and also contains a lot of organic carbon. Results of structural analysis confirmed individual structural properties, porosity and content of function groups in particular. Influence of higher pyrolysis temperature results in slightly lower yields, however it provides products with higher content of organic carbon and higher surface area, in majority of cases. Subsequently, it was found out that short residence time of 10 minutes does not have to be enough for all used biomasses. On the basis of gained data, the preparation or production can be optimalized in effort to make usage of residue biomass more effective in different application, not only in agronomy sector.
