Žerava, Zdeněk ; Houdková, Lucie (referee) ; Boráň, Jaroslav (advisor)
The first part of the thesis is focused on the problems related to sludge and evaluates sludge disposal from waste treatment plants. The thesis mentions factors influencing method selection of sludge disposal as well as it compares sludge disposal in the Czech Republic and in the other states of the EU. It describes a complete waste treatment line and sludge disposal in the area of sludge treatment and disposal. It deals with sludge disintegration and describes the most effective methods of disintegration. The second part of the thesis describes an experimental part of disintegration of waste treatment sludge. An experiment was conducted in the school laboratory in a way of thermal disintegration in the double-surface pressure tank. The disintegration was conducted to temperatures of 60 °C, 90 °C, 120 °C, 150 °C, and 180 °C. We monitored dependence of the sludge dry residue content on disintegration temperature as well as content of suspended solids in liquid fraction (FUGAT). It was possible to choose optimal temperature of disintegration in accordance with processed results.

Education of patients with ulcerative colitis
VEČEŘOVÁ, Iva
My bachelor thesis focused on " Education of patients with ulcerative colitis " has been split in theoretical part and practical part. The theoretical part has been focused on characteristicsof ulcerative colitis and education. This part has been split in nine chapters. The chapters describe anatomy and physiology of colon, definition of the disease, its causes, symptoms and complications. Furthermore, the chapters have been focused on examination methods and treatment of ulcerative colitis and nursing care. The last chapter of the theoretical part has been devoted to education. There were two aims defined for the bachelor thesis; to describe methods of educating the clients suffering from ulcerative colitis and to determine efficiency of education for a patient suffering from ulcerative colitis (in the course of 3 months after the first education). Based on the specified aims, three investigation questions were asked. What is the effect of the suggested education on health status of a client suffering from ulcerative colitis? Does observance of diet measures affect relapse of the disease? How do reasonable physical strain and psychical stress affect the disease? The practical part of the thesis has been processed through qualitative research. The research was made with respondents with the diagnoses of ulcerative colitis and with nurses who work at gastroenterologic ward in the hospital in České Budějovice, a.s. The research was split in three parts. The first part included interviewing of eight respondents with the diagnoses of ulcerative colitis. The interview was semi-structured. This included eighteen questions focused on the progress of the disease, education of the respondent, diet measures and influence of physical strain and psychical stress on the disease. Then, each respondent was educated through the education. The second part included interviewing of three nurses from gastroenterologic ward in the hospital in České Budějovice, a.s. The interview was semi-structured, too. It included sixteen questions which are very similar to allow better comparison with the patients. The third part was focused on check of knowledge and efficiency of former education of three respondents. This was a structured interview. It included five questions. These were focused on present status of the disease, evaluation of observance and efficiency of the low-residue diet and the basis of mental hygiene. The interviews were taken in calm home environment. Results of the research showed that the respondents have lack of information most frequently in the field of physical strain and psychical stress and often in the field of low-residue diet. However, the respondents are mainly well-educated about the definition of the disease and about treatment. In my opinion, my bachelor thesis is helpful because it has proven that correct education may have positive effect on the progress of the disease. The thesis might be also used as education material and it might help improve education of clients with the diagnoses of ulcerative colitis.

The concept and types of bills of exchange and promissory notes
Blaha, Michal ; Zahradníčková, Marie (advisor) ; Čech, Petr (referee)
- 1 - Abstract The topic of my diploma thesis is "The concept and types of bills of exchange and promissory notes". The reason why I chose this topic is my interest in securities law, especially in bill of exchange law, and my previous work experience. I regularly work with bill of exchange law in my employment so this is a reason why I have decided to expand my knowledge of this particular law. The bill of exchange and check act number 191/1950 Coll., as amended, is the basis of legislation for this kind of law in the Czech Republic. The most significant advantage of this act is the constancy, which is given by the general method of treatment of this issue. This advantage can be considered as one of the main disadvantages too, because the solution of unique issues is left to case law and literature. This is a reason, why the core of this diploma thesis is chapter 5, where I analyse the essential requirements of bill of exchange and promissory note. Also the issue of graphical design is a very interesting and actual topic. The diploma thesis is structure into seven chapters. The first chapter is devoted to the historical development of bill of exchange and promissory note. This chapter contains also the historical development of individual institutes of bill of exchange law. The second chapter discusses the...
