Strength-strain analysis of dog prosthesis
Doležalová, Veronika ; Hrstka, Miroslav (referee) ; Vlach, Radek (advisor)
Bachelor thesis deals with strength-deformation analysis of dog prosthesis. Work contains introduction to problems of prosthesis and determination of kinematice during dog’s movements. The analysis was carried out using two approaches, both analytical and numerical. In conclusion, we compare the results of both computational approaches.

Y Chromosomal Characteristics of the Modern Rural Population in Klatovy Region
Doležalová, Veronika ; Ehler, Edvard (advisor) ; Stenzl, Vlastimil (referee)
Usage of genetic markers in non-recombining part of chromosome Y has been shown as a eligible tool for a study of history, diversity and migration of population. Applicable markers of chromosome Y are SNP and STR polymorphisms. There were collected 53 unique samples of DNA as a object of this work from unrelated origin males from 9 villages around Klatovy. Samples have been analyzed and its values have been determined by using the 17 STR markers by AmpFLSTR® Yfiler® Direct Kit. In total I have observed 7 different haplogroups. I have resulted samples from villages around Klatovy and they were analyzed by AMOVA. I have compared samples with the surrounding populations in neighborly Federal Republic of Germany, Austria, Central and South Bohemia. There were no significant differences founded in the genetic profile of this population to the surrounding populations.

Chemiluminescent determination of vitamin B12 using sequential injection analysis
Doležalová, Veronika ; Hraníček, Jakub (advisor) ; Dian, Juraj (referee)
This bachelor thesis deals to find the optimal conditions for the determination of vitamin B12 by the Sequential Injection Analysis (SIA). The basis of the determination is a chemiluminescence reaction in which luminol is oxidized by hydrogen peroxide under the catalysis of cobalt ions in a basic medium. The intensity of the chemiluminescence radiation was measured using a spectrofluorometric detector and the measured intensities were recorded. Suitable experimental conditions were found experimentally before the actual determination. A total of 4 parameters were optimized, namely, the mass percentage of hydrogen peroxide, the ratio between the dosed cobalt ion sample and the luminol solution, the sample flow rate and the luminol concentration. Under optimized conditions, several solutions of known cobalt ion concentration were measured, from which a calibration dependence of chemiluminescence intensity on cobalt ion concentration could be established. For this determination, the basic characteristics were determined. For the determination of vitamin B12 itself by the SIA technique, it was assumed that the vitamin molecule contains exactly one cobalt atom, which was released from the molecule by the action of UV radiation. At the end of the work, the concentration obtained by the measurement was...
