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.

Educational specifics of pupils with autism
Jiříková, Adéla ; Šiška, Jan (advisor) ; Šumníková, Pavlína (referee)
This thesis deals with educational specifics of autistic pupils. In the beginning, the author describes the elemental areas of disorders within the Autism Spectrum Disorders (ASD) and the basic methods applied on work with such disordered individuals. The thesis also briefly presents the system of education of pupils and students with ASD in the Czech Republic. The core of the thesis is constituted by a description of TEACCH Program, which is thought to be the most effective method within the work with autistic students. There is also a research attached to the paper, which is grounded on informations gained from teachers and parents of pupils of the Special nursery school, Special primary school and Special school of ELPIS, where the ASD pupils are handled according to the principles of TEACCH Program. The survey was made by using the method of structured conversation and there were six subjects of the research, six particular pupils. The aim of the research was to find out, how much the treatment in school and at home varies and how are the six subjects influenced by this differences. The results should point out advantages and weaknesses of the application of TEACCH Program in the Czech Republic, show the degree of cooperation between family and school and also can serve as an inspiration for...

Molecular factors of artherogenesis in chronic kidney disease with experimental model of chronic inhibition of Nitric Oxide Synthesis and its Effect of HMG-CoA reductase inhibitoin
Lecian, Dalibor ; Matouš, Bohuslav (advisor) ; Tesař, Vladimír (referee) ; Zadražil, Josef (referee)
The experimental part of the thesis covered the markers involved in nitric oxide deficiency model in rats. The analogue of arginine N-nitro- L -arginine-methyl ester ( L -NAME) was used. L -NAME administration resulted in sustained elevation of BP, decreased GFR, and in higher albuminuria compared to control animals. The administration of hypolipidemic drug - atorvastatin to Wistar rats was studied. The statin used caused lower albuminuria and prevented decreases in GFR in L -NAME rats without having an impact on hypertension. CAV1 protein expression was similar in all groups of rats. In contrast, VEGF expression and RhoA activity was increased in L -NAME-treated animals, and normalized with coadministration of atorvastatin. Clinical part of the thesis focused on the analysis of markers of oxidative stress in obese and non-obese patients with CKD and after kidney transplantation. The patients with CKD had elevated serum concentrations of AGEs, sRAGE and ADMA with the maximal concentrations of AGEs in the patients on hemodialysis. The successful kidney transplantation decreases the AGEs, sRAGE and ADMA concentrations but not to normal value according to general population. Patients with obesity exhibited lower concentrations of sRAGE in CKD as a protective factor for cardiovascular disease. Concentrations of...

Application of trihalomethane formation potential to evaluation of drinking water treatment efficiency
Halešová, Barbora ; Dolejš, Petr (referee) ; Mega, Jaroslav (advisor)
The aim of bachelor thesis was to develop a literature search for the potential creation of oftrihalomethanes (THMs FP) as indicators of water quality in surface water treatment. The THM FP test was monitorated to evaluate the effectiveness of current technological methods of treatment of natural water with special consideration of water with increased content of humic substances. The attention was focused on comparison of the THM FP values with the normally applicable water quality parameters; it means the concentration of dissoluble organic carbon (DOC), UV254, CODMn, CODCr. The obtained evidence suggests that THM FP test allows sensitively assess water quality in term of content of chemically and biologically easily biodegradable organic substances. The potential of THM formation has been proved as a valuable tool for quantify non-specific organic contaminants in treated water, which can usefully complete previously used criteria for assessing quality of treated water.

Substituated Poly(ethylene Glycols) as Drugs Carriers
Pravda, Martin ; Hrabálek, Alexandr (advisor) ; Dittrich, Milan (referee) ; Kalendová, Andrea (referee)
The aim of this dissertation thesis was preparation of drug delivery systems for polyene antimycotics, especially amphtoricin B(AmB). Series of pH-sensitive conjugates of AmB with substituated poly(ethylene glycols) (PEG) have been synthesized and characterized for this purpose. The intermediate PEGs possess a 1,4-disubstituted benzene ring with aldehyde group at the end of the chain. The benzene ring is connected with PEG at its 4-position (with respect to the aldehyde group) by various functional groups (ether, amide, ester). Reaction of terminal aldehyde group of the substituted PEGs with AmB gave conjugates containinga pH-sensitive imine linkage, which can be presumed to exhibit antimycotic effect at sites with lowered pH value. The stability of prepared conjugates under the different physiological conditions was studied. Phosphate buffers (pH = 7,4 or 5,5) were used as model media. Stability of conjugates in human blood plasma and human blood serum was examinated. The imine linkage is split to give free AmB with half-lives of 2-45 min. The rate of acid catalysed hydrolysis depends upon substitution of the benzene ring; however, it does not depend on molecular weights ofthe PEGs used. The conjugates with ester linkage undergo enzymatic splitting in human blood plasma and/or blood serum at pH 7.4...
