PEDAGOGICKÁ FAKULTA UNIVERZITY KARLOVY Abstract Education and preparation for the profession of people with mental disabilities in Teplice region 21.4.2011 Zdeněk Herman Abstrakt Despite all the problems in the Ranks of the cultural environment and the composition of the people after the unemployment I was led to believe it is not always the main factor in recruitment. Or maybe education is not the main determinant, though primarily affiliated, but the nature of personality, diligence and hard work are determinants, which are the quintessence of the employer's requirements. Sometimes such values in the family of people with mental disabilities are more problematic to implement, then the values would lead the school. The success of the equipment of the positive values depends on the quality of the school and its leadership. I knew that in Teplice there are that at least two schools are for high quality and fully prepare people with mental disabilities in practical life. However several shortcomings need to be improved. the largest work can be motivation of pupils with mental disabilities to individual decision-making, working and not being comfortable, aware of the need to work and not wanting to stay at home when they have rent. Motivation is the key factor for improving the quality of life of people.

Pomocí molekulového modelování je možné předpovídat chování nových látek a napomáhá při jinak obtížné interpretaci experimentálních dat. Cílem práce byla predikce vybraných vlastností polymeračních katalyzátorů na bázi karbenů, predikce jejich struktur a spektrálních charakteristik a studie mechanismu polymerace za otevření kruhu laktidu. K ověření chování karbenů a jejich prekurzorů ve formě chloridů byly studovány vybrané charakteristiky molekuly. Byl proveden výpočet vybraných molekulových orbitalů a elektrostatických map. Následně pomocí počítačových programů byly získány teoretické vazebné délky a úhly vybraných imidazolových a imidazolinových sloučenin, karbenů a jejich možných produktů hydrolýzy. Data strukturně podobných, již charakterizovaných sloučenin, byla získána z CCDC (Cambridge Crystallographic Data Centre) a následně byla konfrontována s vypočítanými daty. Byla změřena infračervená a Ramanova spektra imidazolové soli a infračervené spektrum příslušného karbenu. Tato spektra byla konfrontována s napredikovanými. Pro lepší interpretaci spekter byla spočítána spektra možných produktů hydrolýzy. Následně byl studován mechanismus polymerace za otevření kruhu laktidu. Na základě spočítaných energií stacionárních bodů byl navržen nový mechanismus polymerace.

The subject of this diploma thesis is the study of the route of the road I/54 south of the town of Kyjov with regard to the valid zoning plans of the municipalities concerned. The projected bypass will primarily divert traffic off the southern part of the town. The reasons for constructing the bypass are to divert heavy transit traffic, to increase safety in the town and to reduce the negative impacts of transport. The diploma thesis further includes the study of the potential route of the road II/432 west of the city. The projected western bypass is based on the conceptual plans of the South Moravian Region. The western bypass will prospectively divert traffic off the town and enable the connection to the western area of Kyjov.

The main objective of this dissertation is to research the interconnectivity of energy security of the European Union and its relations with Russia. Achieving this goal entails an analysis of the current situation in the EU energy security in the context of its import dependence on Russian energy sources and an outline of the future development of strategic partnership between the EU and Russia in the energy field. The dissertation is divided into five logically arranged chapters. The first chapter provides the theoretical background, the concept of the energy security and methodological researching tools. The second chapter provides an overview of the current state of the global and the European energy industries as a basis for the evaluation of the energy security. The second chapter is also focused on the EU legislative framework concerning energy system. The third chapter deals with analysis of the energy security of the individual sectors and levels of the energy system by determining risk factors and measures to limit their impact. The fourth chapter examines the energy sector of Russia in terms of its impact on the EU energy security. The final fifth chapter outlines scenarios for the future of the EU energy security in the context of relations with Russia.

The diploma thesis is aimed to assesment of the influence of the specimen orientation during the Small Punch Tests (SPT). Steel ČSN 41 0214, or its equivalent steel RFe80, W.-Nr. 1.104 was chosen for experiments. Resulting records from SPT were evaluated using already known correlations which are reported in literature. The correlation values were compared with values obtained by the standard tests like Charpy impact test and tensile test. The influence of axial, radial and tangential test specimens orientation is discussed in relation to Ductile-to-Brittle fracture behaviour of the steel.

The thesis is focused on the prediction of the fracture toughness temperature dependence through a universal curve of fracture toughness (also known as the master curve). To determine the parameters of the universal curve of fracture toughness, values acquired from the measurement results of fracture toughness and tensile tests of structural steel P91 are used. The theoretical part is based on a summary of the relevant information from the field of fracture mechanics and brittle-ductile fracture behavior of steels that are important for the understanding of fracture-strain response of materials depending on load conditions. The experimental part of the thesis contains the results from practical measurements and analyses, which were used for determining the parameters of a universal curve of fracture toughness as well as for the evaluation of fracture behavior and description of the impact of structural parameters on this behavior in case of steel P91.

Předkládaná diplomová práce se zabývá extrakcí nanočástic oxidu titaničitého z produktů osobní péče, konkrétně opalovacích krémů a následnou charakterizací těchto částic. Počet komerčně dostupných produktů s obsahem nanočástic TiO2 se neustále zvyšuje a to se sebou přináší potřebu vyhodnotit potenciální osud a nepřímou expozici TiO2 nanošástic o různých velikostí a tvarů a zkoumat jejich celý životní cyklus. Bylo zkoumáno použití ultrafiltrace a ultracentrifugace jako extrakční metody. Dvě metody pro extrakci TiO2 nanočástic byly vyvinuty a aplikovány na vzorky opalovacích krémů. Extrahované částice mohou být použity pro ekotoxikologické studie, případně experimenty v mesokosmu. Velikost částic byla stanovena pomocí metody dynamického rozptylu světla a transmisní elektronové mikroskopie.
