Kodišová, Lucie ; Otavský, Karel (advisor) ; Mudra, Aleš (referee)
Key words: Charles IV, Luxembourgs, medieval Bohemia, goldsmith, Secular and Ecclesiastical Treasury in Wienna. This bachelor thesis is about significant Czech goldsmith works produced in the 14th century Bohemia which are nowadays located in Secular and Ecclesiastical Treasury (Weltliche und Geistliche Schatzkammer) in Vienna. After depicting of a concise development Viennese court collections the text concentrates on the seventeen works of art, specifically on their history, technical qualities, artistic or art historical charakteristics. The thesis includes several items of the Holy Roman Empire treasury which were modified or supplemented between 1350 and 1378, when Charles IV managed them. Afterwards it discusses tree reliquaries, which became a part of the Holy Roman Empire treasury during the Sigismund of Luxembourg era. The treatise also deals with a Czech royal spehere and scepter, which were used until 1627. In conclusion there are described another three reliquaries deposited in the Ecclesiastical Treasury in Vienna. The possibility of their Czech origin is a matter of great concern for some authors.

Thermal Effects in Physics and Dynamics of Small Bodies of the Solar System
Čapek, David
Thermal Effects in Physics and Dynamics of Small Bodies of the Solar System Abstract of the Ph.D. thesis \s David Capek It has been shown, that the thermal effects are very important in the dynamics of small Solar System bodies. A phenomenon which is known as the Yarkovsky effect is able to secularly change the semimajor axis of an orbit, while the YORP effect affects the rotation state of a body. The Yarkovsky effect and the YORP effect were previously calculated with many constraining assumptions like spherical shapes of asteroids, circular orbits, small variations of the surface temperature, principal axis rotation, constant thermal parameters, etc. We developed a sophisticated numerical model of the Yarkovsky/YORP effect without such simplifications. With this model, we have been able to describe the shape, the orbit, the rotation and the thermal behaviour of an asteroid in a very precise way. The YORP effect was studied on a sample of artificially generated shapes, roughly resembling Main Belt asteroids, and also on several shapes of real asteroids. The depen- dence of YORP on the obliquity and the thermal parameters of the surface were studied (Vokrouhlicky and Capek, 2002; Capek and Vokrouhlicky, 2004). A wide variety of pos- sible YORP evolution paths of the spin state was found. The possibility of...

Molecular and Biochemical Features of Threee Enzymes that May Serve as New Drug Targets in Cryptosporidium Parvum
Čtrnáctá, Vlasta ; Staňková, Marie (advisor) ; Kraml, Jiří (referee) ; Nečas, Emanuel (referee)
Molecular and biochemical features of three enzymes that may serve as new drug targets in Cryptosporidium parvum Cryptosporidium parvum is a unicellular, obligatory and intracellular parasite belonging to the Phylum Apicomplexa. This parasite can infect both humans and animals, causing an acute diarrhea in immunocompetent persons, and a chronic life threatening infection in immunocompromised individuals. Although many drugs, to combat this parasite, have been empirically tested, there is no completely effective therapy to treat cryptosporidiosis in humans or animals. In recent years, the completion of the genome sequencing projects in C. parvum and C. hominis along with advances in molecular methods have significantly helped to increase our general understanding of the C. parvum metabolic machinery. However, our knowledge concerning many specific pathways and enzymes in Cryptosporidium is still limited. Their better understanding in this organism would aid in experimentation of new drugs and new strategy development to treat cryptosporidiosis in humans and animals. In this dissertation, three essential metabolic enzymes of C. parvum have been tested: Pyruvate:NADP + oxidoreductase (PNO) is a unique, core metabolic enzyme, responsible for converting pyruvate to acetyl-CoA. It is a rare fusion of an...

Analysis of videokymographic images
Zita, Aleš ; Zitová, Barbara (advisor) ; Novozámský, Adam (referee)
In ongoing basic human vocal chord functionality research, scientists try to describe the dependency of the glottal wave characteristics on tone generation and vocal chord properties. One of the affordable vocal chord visualization techniques for clinics is the Videokymography - technique based on recording the vocal chord vibration using a CCD camera modified to a line-scanner. Recorded rows are than combined to form a spatial-time recording. These records are suitable for computer based extraction of the vocal chord characteristics, including the characteristics of the glottal waves. In this thesis the method for automatic detection of the glottal waves was developed and implemented utilizing the digital image processing techniques. The proposed method is primarily focused on processing the healthy vocal chords videokymographic images as they gives us a good reference for the physiology of the human vocal chord organ.

Medical Services from the Point of View of People with a Sight Handicap
Nováková Peršínová, Lenka ; Holmerová, Iva (advisor) ; Jarolímová, Eva (referee)
My thesis deals with the provision of medical services to people with a severe sight handicap. My research focuses on fully blind people. The aim of my thesis is to find out the situation of these people within medical facilities. I try to reveal blind people's experience of how healthcare workers communicate with them, how well prepared healthcare professionals are and how blind people themselves are prepared. I also examine what technical obstacles are encountered by blind people in medical facilities during the provision of medical services. My research is conducted by means of a quality approach and I have held semi-structured interviews with 16 informants. The theoretical section of my thesis includes a brief anatomy and physiology of the optic tract, the development of visual perception, visual impairment classification according to the WHO, the most common types of eye defects, a brief description of the development of persons with a visual impairment, a brief psychology of a handicap, what people with a visual impairment need to have a good spatial orientation and the possibility of unassisted locomotion, the requirements for healthcare facilities to be able to be used without barriers, the principles of being in contact and communicating with persons with a sight handicap, a model governmental...

Magnetooptical properties of semiconductor quantum structures
Uxa, Štěpán ; Grill, Roman (advisor)
Title: Magnetooptical Properties of Semiconductor Quantum Structures Author: Štěpán Uxa Department: Institute of Physics of Charles University Supervisor: Assoc. Prof. Roman Grill, PhD Supervisor's e-mail address: grill@karlov.mff.cuni.cz Abstract: In this theoretical work, a detailed study of optical properties of excitons in double quantum wells subject to magnetic and electric fields is presented. Starting from the well-known Luttinger formulae describing the real valence-band structure of III-V semi- conductor compounds, we developed an efficient way to solve the Schrödinger equation of a coulombically-bound pair electron-hole forming an exciton. Derived formulae were illus- trated on relevant figures, giving us an opportunity to better understand the effects of external fields on the studied system. Dispersion relations, the shift of energy levels in an electric field, absorption and photoluminescence spectra, and charge density distribution were calculated and achieved results were discussed in detail. Keywords: exciton, double quantum well, coupled quantum wells, Luttinger (-Kohn) hamiltonian, valence-subband mixing

Image processing within determination of topographic surface parameters
Boháč, Martin ; Ohlídal, Miloslav (referee) ; Šťastný, Jiří (advisor)
This work deal with determination topohraphic parameters of a randomly rough surface by the help of method of shearing interferometry. It is a optical method for determination surface roughness. The basic idea is based of on deformation interference strips which are made by interference of the same mutually translated monochrome luminous wavefronts. The wavefront is created after transit or reflection monochrome lights from the surface of a studied sample. The wavefronts creates picture with deformed interference strips , which carries information about character of the surface. This information can be profited by algorithms of image processing from the picture . The thesis was developed in research project MSM 0021630529 Intelligent Systems in Automation.
