TiO2 pillared clay for photocatalytic purposes
Fiala, Michal ; Šoukal, František (referee) ; Ptáček, Petr (advisor)
Bachelor’s thesis describes preparation of mixed catalytic systems kaolin/ TiO2 and metakaolin/ TiO2. Samples were prepared via hydrolysis of TiCl4 in kaolin suspension. Catalyst metakaolin/ TiO2 was prepared by calcination of this material under static oven atmosphere at 600 °C. Thermal analysis (simultaneous TG-DTA), infrared spectroscopy (FT-IR) and electron microscopy (REM) were used for samples characterization. Catalytic efficiency of mixture kaolin (Sedlec Ia) or metakaolin with TiO2 (anatase) was compared with pure kaolin. Experiment is based on oxidation of ethylalcohol, which was introduced in to reactor in flow of inert gas (argon). Amount of decomposed ethylalcohol is proportion to concentration of oxygen in gas product outputting from reactor. System kaolin/ TiO2 show higher catalytic performance than metakaolin/ TiO2 catalyst.

Beránek, Tomáš ; Žádný, Jaroslav ; Jakubík, Pavel ; Církva, Vladimír ; Storch, Jan
In this work we focused on preparation of novel bidentate and fully aromatic N,N-ligand and its ruthenium complexes. 6,7-Diaza[5]phenacene (1) was synthetized from 4-bromoisoquinoline by microwave-assisted tandem Hyama-Heck cross coupling reaction3 followed by photocyclization (Scheme 1). With 6,7-diaza[5]phenacene (1) in our hand, we prepared some new ruthenium(II) complexes (e.g. 2) , characterized them from structural point of view and determined some of their electronic and optical properties with regard to their application potential.

Vzdělávání jedinců s poruchou autistického spektra na střední škole
Dvořáková, Jitka
My bachelor thesis deals with secondary education of people diagnosed with Autism spectrum disorder (ASD). The aim of my theoretical part is to summarize the education possibilities for ASD children in South Moravia region based on comparison of particular opinions of different authors and school legislation. The information will clarify the current situation concerning counselling services for ASD patients. There will be also listed counselling offices in South Moravia available for ASD patients. ADS patients' possibilities of inclusive education and principles of work with them used during upbringing and educating will also be analysed. The theoretical part also includes the definition of autism, its etiology, a triad of symptoms, particular kinds of students and cognitive processes of people suffering from this disorder. The analysis and synthesis of available information, reference literature study and comparison of statistic data will be used in the theoretical part. The practical part targets at revealing the problems teachers and other pedagogical staff might be experiencing while integrating and educating ASD students at secondary school. One of the fractional aims is also collect the opinions of pedagogical assistants -- what they think of secondary education of ADS individuals, how they prepare the individual curricula of students. To get this information dialogues with pedagogical assistants will be used. As far as the main object of the thesis is concerned, questionnaires collecting data will be used. It will be aimed at problems teachers and their assistants are facing while integrating ASB students. Respondents are teachers of the "Střední zahradnická škola" in Rajhrad who participate in educating the above mentioned students. The results of questionnaire survey will be the base line for a dialogue with a specialist from Specialized Pedagogical Centre in Brno (Štolcova street). The obtained data will be analysed and interpreted so that the outcome of the whole survey could form a handbook for secondary school teachers who work with ASD students.

Synthesis of unsymmetrical derivatives of azaphthalocyanines and their complex formation with pyridine
Žižkovská, Jana ; Zimčík, Petr (advisor) ; Miletín, Miroslav (referee)
1. Summary Synthesis of unsymmetrical derivatives of azaphthalocyanines and their complex formation with pyridine Mgr. Jana Žižkovská Department of Pharmaceutical Chemistry and Drug Control Faculty of Pharmacy in Hradec Králové, Charles University in Prague I prepared the mixture of six possible products (AAAA, AAAB, ABAB, AABB, ABBB, BBBB) using a statistical condensation starting from two different precursors - 5,6- bis(diethyamino)pyrazine-2,3-dicarbonitrile (A) and 5-diethylamino-6-[2-(4,4'- dimethoxytrifenymethoxy)-ethylamino]pyrazine-2,3-dicarbonitrile (B). Only compound of AAAB type was isolated by column chromatography from the mixture, purified and was characterized by NMR, IR, MS, UV-VIS spectroscopy. The precursor (B) was changed - 5-diethylamino-6-[2-(4,4'-dimethoxytrifenymethoxy)- ethylmethylamino]pyrazine-2,3-dicarbonitrile - and the statistical condensation was done the same way. Unfortunately the desired AAAB product was unstable and therefore the work was finished. In another part of this work I have studied a formation of proton-transfer complex with two molecules of pyridine. Three different AzaPc with hydroxy groups on periphery were used in this study. The influence of hydroxy groups on the rate constant was not confirmed. Then I used only one AzaPc -...

Role of Psb28 proteins in the biogenesis of the Photosystem II complex in the cyanobacterium Synechocystis sp. PCC 6803
BEČKOVÁ, Martina
The thesis focuses on the role of Psb28 proteins, namely the Psb28-1 and its homolog Psb28-2, in the biogenesis of the Photosystem II complex (PSII) in the cyanobacterium Synechocystis PCC 6803. The aims of this work were to localize the proteins within the cells, and to determine their function. A fraction of both Psb28 proteins was identified in the monomeric PSII core complexes but most proteins were found in the unassembled protein fraction associated with thylakoid membranes. Psb28-1 was mostly detected as a dimer while Psb28-2 as a monomer. Psb28-1 also differed from Psb28-2 by its higher affinity to the PSII core complex lacking CP43 antenna. Characterization of Psb28-less mutants suggested regulatory function of the proteins in PSII biogenesis in connection with chlorophyll biosynthetic pathway. Analysis of preparations isolated using FLAG-tagged versions of Psb28 proteins showed their association with Photosystem II - Photosystem I supercomplexes, especially under increased irradiance, and supported a role of Photosystem I in the PSII biogenesis.

Study of magnetic nanostructures for spintronics
Kameš, Jaroslav ; Nebojsa, Alois (referee) ; Urbánek, Michal (advisor)
The Cu/NiFe/Cu/Co/(CoOx) spin-valves have been prepared by the ion-beam sputtering method. Their GMR ratio and the time stability have been investigated by the magnetoresistance and the MOKE measurements at room temperature. The reproducibility of the preparation of the samples have been studied as well, i.e. two identically configurations of the layers should have the same magnetotransport properties.

The Specifics of Nurse´s work on a Psychiatric Ward
HŘEBEJKOVÁ, Blanka
Theoretical background Psychiatry belongs to fundamental branches of medicine. Its task consists of diagnostics, treatment and prevention of mental diseases. Psychiatry includes adult psychiatry, child psychiatry and adolescent psychiatry, gerontopsychiatry, psychiatric addictology, psychiatric sexulogy with psychiatric rehabilitation. Nowadays, importance of the psychiatric branch is increasing; according to epidemiologists, we can see a slightly upward trend in the number of psychiatric patients. Work of a nurse in the department of psychiatry differs considerably from work in other standard departments. Such work is demanding both physically and mentally. In the department of psychiatry, it is extremely necessary that the nurse builds up a close relationship with the patient and acquires their confidence. Goals of the thesis The goal of the thesis was to map differences relating to work of a nurse working in the department of psychiatry, to find out what communication skills a nurse working in the department of psychiatry must have and in addition, to find out what the possibilities of further education within the framework of life-long education for nurses working in the branch of psychiatry are available. Methodology The qualitative methodology was applied to the research. The data were obtained by the interview method. Prior to execution of the research as such, the staff nurse was asked for permission and she agreed with execution of the research concerned. In cooperation with the charge nurse and the head nurse of the department of psychiatry, seven interviews with the nurses were made. The interview consisted of twelve questions and was absolutely anonymous. The written records of the interviews were analysed and the results were divided into categories and sub-categories subsequently. Results Based on the research, it was discovered that work of nurses in the department of psychiatry is much different from work thereof in other departments. The nurse working here should be interested in the field and should have good knowledge of the psychiatry-related issues. The nurse working in the department of psychiatry should be competent, resourceful and should be well informed of the patients to be able to perceive early possible changes in their behaviour. In the psychiatric nursing care it is important in particular to communicate correctly with various types of patients. Therefore, it is vital for the nurse to be well versed in mental diseases and symptoms thereof. Behaviour, perception and communication of the psychiatric patient are often affected by the disease as such. There are various communication barriers which the nurse has to cope with. Therefore, the nurse should be able to use all components of verbal as well as non-verbal communication correctly. Preparation for incidents consists of in particular regular training in the area of occupational safety and protection of health at work, fire protection and study of methodological guidelines and standards of the department of psychiatry. Certain preparation for incidents is included as well. There are sufficient possibilities of further education in psychiatric nursing care available. As it followed from the research, the nurses show active interest in education and search therefor independently. The nurses are sufficiently supported by their superiors in the search for suitable educational projects. Conclusion Considering the overall view of the thesis results, it is possible to say that the research questions were answered and the set goals of this thesis were achieved. The results of this bachelor's thesis may serve as supporting source material for lectures on nursing care in departments of psychiatry. In addition, the thesis may serve students as study and source material for their own studies and work.
