Design of airframe mold for ultra-light aircraft manufacturing
Zatočilová, Aneta ; Dočkal, Aleš (referee) ; Paloušek, David (advisor)
This diploma thesis deals with digital data processing during the design of a mould of ultralight airplane airframe. The final digital model meets the demands on manufacturability by using CNC machining. The realization, in compliance with the reverse engineering approach, was conceived in four phases, which had to be solved step by step in order to preserve the continuity of the process. The phases correspond to the main chapters of the practical part of the thesis. The first part is focused on 3D digitalization of airplane fuselage by using an optic scanner ATOS and photogrammetric system Tritop. The result of this part is digital data of fuselage geometry in form of polygon grid. Next part deals with software reconstruction of collected data – by optimizing polygon grid in order to provide suitable base for surface modeling. The third part, the most time demanding, handles the creation of airplane fuselage surface model. Geometry has to satisfy requirements for smoothness and tangential or curvative connection of surfaces, including other requirements resulting from model usage. The final part of the thesis documents the procedure of deriving a mould from the aircraft fuselage geometry.

The motivation of blood plasma donors between the ages of 18 to 26 in the Czech Republic in 2016
Vilímková, Helena ; Barák, Vladimír (advisor) ; Krebs, Vojtěch (referee)
This bachelor thesis deals with the motivation of blood plasma donors between the ages of 18 to 26 in the Czech Republic in 2016. The first part of the work defines and describes the system of blood donation and its components in the Czech Republic. Furthermore, the work examines fundamental theoretical concepts concerning blood plasma donation and it also explores private plasmapheresis donation centers. Finally, it inspects the motivation of blood plasma donors. The practical part of the thesis analyses author s empirical research. The collected data showed that the biggest motivation factor is financial compensation, despite the fact that positive feeling about oneself goes hand-in-hand with the financial reward in most of the cases. The rationale behind this practice is student s need to enhance their financial situation as they are yet to have full income.

Algorithm of imaging methods in suspicion on pulmonary tuberculosis
MIKULÁŠOVÁ, Jana
Tuberculosis is an infectious disease which more than 8 million people are taken ill with throughout the world every year. During the last decade more than 30 million people succumbed to it. The Czech Republic succeeds in decreasing the number of TB cases, despite of it the physicians warn how dangerous is still this infectious disease. Basic diagnostic examination in pulmonary TB is an X-ray examination. Radiophotography, so called {\clqq}štítovka`` enacted remarkable part in combating TB. This apparatus was used in past for collective X-ray examination. The disadvantage of this technique is substantionally higher radiation load. In my work I dealt mostly with contemporary possibilities of radiodiagnostics in pulmonary TB examination (with regard to radiophotography). I carried out measurement of entering surface kerma with the help of water phantom in different work places, with different types of machines. In my thesis I compared examination techniques, both from the point of diagnostic yield , and from the point of patients´ radiation load. X-ray diagnostics participates in big rate in medical irradiation, which is the most important part in human irradiation from artificial radiation sources. Implementation of new diagnostic methods (especially computer tomography) resulted in important expansion of diagnostic possibilities . On the other hand, historical equipment still functions, e.g. cabin machines for imaging from the photographic plate. The most important factors affecting radiation load of patients is modern machine equipment, regular running of tests of long-term stableness and working steadiness , as well as protective aids use. In every work place with sources of ionizing radiation a permanent supervision on respecting of radiation protection rules must be ensured.

Early diagnosis of occupational asthma is important especially for the prognosis of this disease. The confirmation of the diagnosis of occupational asthma is sometimes difficult using diagnostic methods available nowadays. That is why searching new methods is very important. Analysis of exhaled breath condensate (EBC) by liquid chromatography combined with mass spectrometry enables the separate detection of cysteinyl leukotrienes (LT) - LTC4, LTD4, LTE4; LTB4 and 8-isoprostane. If patients with occupational asthma and controls were compared, only LTC4 was significantly higher among all EBC parameters studied in asthmatics (despite corticosteroid treatment). This marker could be used in the future diagnostics. Monitoring of 24-hours variability of EBC parameters in patients, in whom occupational asthma is suspected, showed relatively high intraindividual and interindividual variation. It is evident therefore, that if only one daily measurement in asthmatics would be possible (which is common in articles of several authors), it should be collected in the same period of day in all persons. In negative bronchoprovocation tests significant changes of EBC parameters were not found. The evaluation of positive bronchoprovocation tests was limited by small number of patients, however in five persons from six, the...

The possibilities of use of the robotic system da Vinci for treatment of localized prostate tumor
Podzimek, Michal ; Kočárek, Jiří (advisor) ; Kolombo, Ivan (referee)
Cancer of prostate is the most frequent male malignity and also it is the second most common cause of death in Europe and in the USA. There are 2 228 new cases reported in the Czech republic per year. The probability of occurrence of this disease is one to six during whole life. There is a good success in detection of his disease in the early stage due to development of screening methods. In such case the radical prostatectomy is very successful method of treatment. Besides of operation methods like open radical prostatectomy and laparoscopic prostatectomy there is a new operation method using robotic system da Vinci. The aim of this machine is to bring the advantages of the miniinvasive surgery together with keeping intuitive handling like in open surgery. First da Vinci system was bought and installed in the Central military hospital in Prague, Czech republic in 2005. The common knowledge about using this method is very low in both general public and specialists. Nor patients, neither their doctors often know about possibility of surgery using da Vinci system. The main objective of this thesis is to evaluate almost three years of experience of treatment localized prostate tumor using da Vinci system, and to describe its possibilities, benefits and disadvantages. Collection of 255 patients files aged...

The introduction is devoted to directives that make up a harmonized legal framework and the Czech legislativ, which specifically prescribes behaving of depositories. The main part is devoted to the depositary functions, such as operating in the Czech market conditions. This part of work is focused not only on the distribution of the depositary market, but also on the collected amount of the fees, the efficiency of regulation in the real market enviroment and in the importace of depositories in the Czech market. The final section is devoted to the findings, including the final assessment of the depositaries. As a first of its kind, this thesis gives a comprehensive view of activity of depositories and their importace for the Czech market, as the depositaries represent entities that control whether funds act in accordance with the legislation. Depository oversees as to prevent fraud and to qualified investors or collective investment contributed to the further development of the capital market, which is necessary for the further development of all economic sectors.
