Experimental investigation of a control synthetic jet
Němcová, L. ; Kordík, Jozef ; Trávníček, Zdeněk ; Kopecký, V.
Synthetic jets were used in previous studies to control a continuous round air jet. This study focuses on the single synthetic jet, which is measured using Constant Temperature Anemometry (CTA) and Particle Image Velocimetry (PIV). Velocity profiles and frequency characteristics of the single synthetic jet are discussed and the velocity maps at frequencies of 30 Hz, 81 Hz and 190 Hz are presented. Finally, velocity, flow rate and momentum coefficients featured the present flow control are evaluated, and examples of actively controlled round air jet are put on. The results confirm efficiency of the present flow control method.

Splicing of atypical introns in S. cerevisiae
Cit, Zdeněk ; Půta, František (advisor) ; Pichová, Alena (referee)
Pre-mRNA splicing is a vital process of gene expression important for all eukaryotic organisms. For the proper function of this very complex and dynamic event the presence of few specialized RNA and many proteins that hold a variety of tasks is necessary, not only inside the splicing complex itself, but also beyond this complex. The Prp45 is one of the proteins involved in pre-mRNA splicing in yeast Saccharomyces cerevisiae. Its human homologue, SNW1/SKIP, is involved in splicing but also in other crucial cell processes. The Prp45 protein was reliably reported only to participate in the second transesterification reaction of splicing. But there are also data suggesting its possible involvement in the first transesterification reaction. This work provides further evidences linking protein Prp45 with the first splicing reaction, obtained by the research of cells carrying the mutant allele prp45(1-169). Cells carrying this allele show dropped splicing and accumulation of pre-mRNAs. This thesis therefore also investigated the possible influence of Prp45 protein on the RNA export from the nucleus to the cytoplasm. But no connection between this protein and RNA transport was discovered. Keywords pre-mRNA splicing; Saccharomyces cerevisiae; Prp45; Mer1; Mud2; Prp22; Rrp6; AMA1; SNW1/SKIP

Anti-Plague texts in the late Middle Ages and the Early modern period.
PAMPUSCHOVÁ, Marie
The theme of this work are late medieval and early modern time anti-plague treatises and official regulations against plague. In times when many countries and even continents were affected by plague, many city councils and rulers themself had the treatises printed in order to reduce the risk of transmission of the infection and development of the illness. The treatises adjusted regulations of towns and villages. These official decrees against plague were supplemented with plague treatises that were written for inhabitants of towns affected by black death. Many of them were written in Latin and therefore incomprehensible to uneducated people. It changed when a doctor Jan Černý wrote such a treatise in Czech language. The treatises advised not only how to prevent plague but also how to treat it. I divided my work into two parts. In the first part I describe particular plague epidemics that took place especially in Bohemia and Moravia. I progressed chronologically from antiquity to the 18th century and described whole course of epidemics in various regions. In the second part I focused mainly on different ways how these treatises deal with prevention and treatment of the disease. I made a comparison of various plague treatises from Prague, České Budějovice and Nepomuk. In order to gather data and informations I focused on historical sources and literature that give us informations from people who had first-hand experience of plague. I do the overall comparison and critique of these sources in seperate chapter. I believe this work can work as an educational material for students and teacher

Initial Stage of Mutual Diffusion of Carbide in Iron
Čermák, Jiří ; Král, Lubomír
Initial stage of mutual diffusion close to carbon/iron interface was investigated in the present work. SIMS technique of concentration profiles enabled to study the carbon redistribution in the very early stages, when the diffusion process occurs – at least partly – in regions, where the carbon concentration exceeds the carbon concentration limit. It was observed that carbon diffusion coefficients are much lower under such conditions, than in Fe matrix with equilibrium carbon concentration. The measured carbon diffusion coefficients approached values reported for carbon diffusion in carbides.

International involvement in the peacebuilding process on Sri Lanka
Mojžíš, Michal ; Havlová, Radka (advisor) ; Burešová, Jana (referee)
The final months of Sri Lankan civil war, the 26 year military campaign between the Government of Sri Lanka and the insurgent separatist organization Liberation Tigers of Tamil Eelam, are marked by allegations of war crimes committed by both parties of the conflict, including attacks on civilians, summary executions of prisoners, enforced disappearances, restrictions on humanitarian assistance and recruitment of children. Since the attempts to put the Sri Lankan issue on the agenda of the United Nations Security Council failed on the unwillingness of China and Russia, the UN bodies in Geneva have taken a leading role in promoting the peacebuilding process on the island. The thesis aims to analyse the impact of the Geneva-based human rights bodies, in particular of the United Nations Human Rights Council, on the process of reconciliation in Sri Lanka, for which is crucial that the alleged violations of human rights in the last months of the civil war would be properly investigated and that the perpetrators would be held accountable. In order to put the activity of the UN Human Rights Council into broader context, the paper will examine the political development in Sri Lanka since the end of the civil war in 2009 as well as the failed efforts of Sri Lankan governments to launch the process of reconciliation.

Nursing care for woman at minor gynecological surgeries
KÁPLOVÁ, Veronika
Minor gynecological surgeries are defined as surgeries after which the patients are dismissed from hospital to home care within 12 to 24 hours. The purpose of pre-surgery care provided by a midwife is to ensure thorough somatic and mental preparation of the patient for the surgery. The patient is required to sign all necessary consents with the surgery, she shall be informed about the course of pre-surgery care, the surgery itself, post-surgery recovery and naturally also about all risks involved. The result of a consistent instruction provided by a midwife shall be a patient who is calm and mentally prepared for the surgery (Henková, 2010; Repková, 2006). The bachelor thesis includes a theoretical part and a practical part with research. The theoretical part focuses on minor gynecological surgeries and nursing care before and after the surgery. The objective of the bachelor thesis was to survey the level of awareness among women about minor gynecological surgeries. Two research questions were formulated to meet the objective: what the level of awareness about minor gynecological surgeries is among women and which method of information provision would be appreciated by women. The research part of the bachelor thesis employed the method of qualitative survey. The data were collected by means of semi-structured interviews. The surveyed set of respondents consisted of 8 women. The interviews were conducted from the beginning of February to the end of March 2014. The survey was expected to provide information about whether the women had been sufficiently informed about minor gynecological surgeries. For the category of pre-surgery period we investigated the following: What is the experience of women with previous nursing care? To what extent were the women informed by their local gynecologists and were they sufficiently informed in the hospital before the surgery? The results have shown that most of the respondents did not have any previous experience with nursing care. Two respondents said that they had previously undergone a minor surgery and that they were content with the nursing care. Results of the survey have shown some gaps in the form and quantity of information provided in medical offices of the local gynecologists. One half of the respondents were not content with the information provided in the medical offices. The information provided in the hospital before the surgery was assessed positively by five respondents out of eight and they appreciated particularly the personal and accommodating approach, professional conduct and empathy. For the category of post-surgery period we investigated how the respondents saw the approach of the nursing staff in the operating room. The results have shown that the respondents evaluated positively particularly the fact that the physician introduced himself/herself to the patient and provided information about the subsequent care. For the category of post-surgery care we also investigated subjective feelings of the respondents after the surgery, their awareness of the post-surgery regime at home and the form of information provision. Results of the research suggest that patients are highly perceptive, particularly when it comes to friendly gestures and words. The information about the home post-surgery regime was rated positively by one half of the respondents and negatively by the other half. On the other hand, they appreciated the personal and accommodating approach and professional conduct. Most of the respondents were content with the form of information provision. Some of them would have appreciated to have a leaflet or information brochure containing all important information. The theoretical part of the bachelor thesis can be as used as a study material for future students of midwifery at the Faculty of Health and Social Studies of the University of South Bohemia.
