The preparation of biocompatible silver nanodispersions by the reduction of their solutions
Ulahelová, Jana ; Dittrich, Milan (advisor) ; Kvítek, Libor (referee)
The aim of the thesis was focused into the range of factors influencing the size of silver nanoparticles usable as antimicrobials prepared by Tollens method. This method is based on reduction reaction of silver salts or silver complexes with reduction agents. Mono-, oligo-, and polysacharides are regarded as the most useful compounds for this purpose with regard to their minimal toxicity and high biocompatibility. It was concluded that various hydrodynamic conditions realized via usual stirring by laboratory stirrer, or microwaves source action, or in relatively static conditions, don't influence the condensation process in the different extent. Temperature rising to 85 řC didn't influence the size of nanoparticles also. Polymers and oligomers, as polyvinylalcohol, starches, and polydextroses has been found as the very appropriate reduction agents. The prepared samples consisted of very fine nanoparticles, the size characteristics represented by intensity and volume diameters were in the order of units of nanometers, the polydispersity indexes were of very low values.

ŠÍMA, Oldřich
This diploma thesis is aimed at assessing the provision of emergency electric power supply to hospitals in South Bohemia. The chapter titled Present State briefly characterises the generation of electric power, the history of power plants in the Czech Republic, the power distribution system, it lists the basic elements of the power distribution system, including its stability and security. Among other things, it presents the term of blackout and its potential impact on the society. Furthermore, this chapter deals with the infrastructure in relation with the critical infrastructure and its history. At the end of this chapter, the functioning of health service is mentioned in relation to emergency situations, including the emergency sources used by hospitals.

Molecular modelling - Structure and Properties of carbene-based catalyst
Kulovaná, Eva ; Zmrzlý, Martin (referee) ; Richtera, Lukáš (advisor)
Molekulové modelování umožňuje předpovídat chování nových látek a napomáhá při jinak obtížné interpretaci experimentálních dat. Záměrem našeho studia byla predikce vybraných vlastností polymeračních katalyzátorů na bázi karbenů, predikce jejich struktur a spektrálních charakteristik. K ověření chování karbenů a jejich prekurzorů ve formě chloridů byly studovány vybrané charakteristiky molekuly. Byla provedena vizualizace vybraných molekulových orbitalů a map elektrostatických potenciálů a elektronových hustot. Následně pomocí počítačových programů byly získány teoretické vazebné délky a úhly vybraných imidazolových a imidazolinových sloučenin a z nich připravených karbenů. Data strukturně podobných, již charakterizovaných sloučenin, byla získána z CCDC (Cambridge Crystallographic Data Centre) a následně konfrontována s námi vypočítanými daty. Byla změřena infračervená (IČ) a Ramanova spektra imidazolové soli a IČ spektrum příslušného karbenu. Tato spektra byla konfrontována s napredikovanými.

Role of social worker in a hospital
Svobodová, Nikola ; Tomeš, Igor (advisor) ; Šámalová, Kateřina (referee)
The diploma thesis is focused on the main activities of the social workers at the hospitals in Prague, the regional hospitals, and one former district hospital. Within the theoretical section of the abstract there are clearly defined fundamental concepts of social work in health care and its historical transformation. The chapters consist of four sections: ethics code, the quality of social work at the hospital, valid legislation, as well as interdisciplinary collaboration within the hospital. The theoretical part focuses on job description, competencies, skills or personality characteristics of the social worker in the hospital. The last section describes social work in the hospitals by different target groups with whom the social workers can come into contact. The empirical part of this diploma thesis is acquired by the semistructured interviews. The main research question tries to find out the role of the social worker at the hospital. The research targets three surveyed areas: The first examines the qualification skills of the social worker at the hospital. The second refers to the job description of the social worker at the hospital's core business activities. The last part of the research is dedicated to interdisciplinary collaboration among hospital staff. The discussion consists of compared...

The shooting accuracy of junior basketball in different levels ( regional league, junior league)\\
ROUBÍČEK, Martin
In my thesis I have been dealing with shooting accuracy of juniors in Bohemia Poděbrady in regional league. The aim of my work was to find out the effectivenes of shooting during matches, from particular positions and distance. The data were gained from technical records during one season period. The gathered data were compared with the results of technical records of juniors playing the first junior league and with the results of a shooting test in noncompetitive conditions. The examined group contained thirty players. Obtained results will be used for improvement of shooting training of juniors in Bohemia Poděbrady and can be the basement for works of similar kind.
