Choosing suitable and safe valve with accessories depends on general specifications for plant. Using valve for on/off, throttling, back-flow prevention, etc., pressure drop is related with Kv value or leakages from piping systems are main factors for properly valve selection. Valve have to resist chemicals and substances that may change the state, temperature and its fluctuation, pressure, corrosion and erosion. This properties determine pressure class, temperature resistance, connection into pipe and sealing material as gland packing, seats, seal between flange etc. This and other specification, listed in this thesis, can help determine suitable type of valve. This thesis deals construction design of valve and accessories as well. The last chapters are focused on calculation of safety valve and selection safe and appropriate control valve with accessories.

CHARLES UNIVERSITY IN PRAGUE FACULTY OF SOCIAL SCIENCES Institute of Sociological Studies Pavla Procházková How people buy on internet Abstract of the Diploma Thesis This thesis describes the basic principles of human behavior in shopping on the Internet. The aim was to tell whether shopping on the Internet is rational. The work deals with theories of rationality and bounded rationality theories from the perspective of sociological, economic and psychological approaches. All theories agree that the man is rational, selects the most efficient option of possible behavior. Whether the benefits gained are economic, social or psychological. From this broad perspective, it is clear that people in most cases their actions are rational, because even the deepest emotions have some rational basis, however, that over the centuries They lost its effectiveness. Perhaps it may be irrational today due to too rapid growth of technology, information overload (information is becoming more and more widely available, but their understanding is worse, a man must decide which of them to follow). Internet for shopping feature brings greater rationality in their instruments. It also restricts such perceptions, which reduces the rationality of choice. The conclusion is that people act rationally on the Internet, buying in order to...

The problem of the sustainability of the welfare state became over several last years one of the most important political, medial and social topics in the Czech republic. Recent experience from countries of southern Europe are showing, that large welfare states are in their current size economically unsustainable, because they significantly participate on creating public budget's deficits and on the growth of government debt. In this master's thesis I deal with exploring the possibility, that political parties in the Czech republic conduct a reduction of the Czech welfare state's size. The thesis draws on the economic theory of democracy developed by Joseph Schumpeter and Anthony Downs and the argumentation builds on its assumption that political parties are rational actors motivated purely by gaining votes and winning elections. Based on this assumption, I develop an economic model of partisan decision-making and conclude conditions, that allow political parties to decide rationally in accordance with their assumed motivation to conduct the reduction of the welfare state. The fulfillment of these conditions is consequently being empirically analyzed for the specific case of the Czech republic. The results of my analysis show, that none of these conditions is fulfilled in the Czech republic - by...

As methodological basis for the research critical discourse analysis was selected, completed by analysis of metaphors. The thesis is based on the theoretical framework composed of the following concepts: 1/ discursive reproduction of the racism by so called symbolic elites, 2/ new racism and 3/ construction of national identity. The thesis also presents the social and political context of the election. The main objective of the research is to answer the following research questions: How does the political discourse of presidential candidates deepen the gap between positive self-presentation and negative presentation of the others? And to which extent in the discourse of individual candidates can it be seen? The thesis describes specific topics, topoi and discursive strategies which are used by the candidates.

The presented Thesis "Political Communication and Politainment in the Presidential Election in the Czech Republic in 2013" analyses political communication in the historically first presidential election campaign in the Czech Republic. I saw the presidential election as an opportunity to research a new platform of political communication that politainment is. The primary aim of the Thesis is to introduce this concept in the context of the current nature of political communication and at the same time to identify variables defining this phenomenon in the Czech environment. Analysis of the elements of politainment is performed on campaigns of the two most successful candidates aspiring for the office of the President of the Czech Republic - Miloš Zeman and Karel Schwarzenberg. I focused primarily on the television appearance of both candidates in TV debates broadcasted by Czech Television, which were the climax of the entire presidential campaign. I was interested in the content of communication of both candidates and the overall character of the debates. The Thesis answers the following questions: What is political communication and its role in politics? How does its form change over time? Does personalisation of election campaigns result in the emergence of politainment as a phenomenon of political...

The objective of the submitted diploma thesis is to analyze the subject of a direct democracy system in the Czech Republic focusing on the local level of governance. The possibility of being able to participate imminently in the municipal government and thus amending the current representative model became the subject of not only political discussions over the last few years. The thesis is composed of a foreword and five chapters, which are hereafter divided to subchapters for better transparency. Findings and author suggestions concerning the possible future forms of the local democracy are summarized in the conclusion. The introductory chapter presents the direct democracy in a theoretical way and shows how it differs from the representative democracy model. It also contains the definition of the five most respected forms of a direct democracy, which are: referendum, plebiscite, citizen initiative, petition and recall. Following two chapters are focused on the situation in Czech Republic, first in general, then with an emphasis on the municipal scene. Efforts to establish an individual form of a direct democracy can be observed already from the year 1918 with various results, new possibilities appeared later as Czech Republic had entered supranational communities. A local referendum still remains...

(in English) This thesis deals with the choice of the Czech secondary vocational schools. Through a description of important theoretical approaches connected to the education and a study of the Czech educational system, the paper is getting to the analysis based on qualitative interviews analysed in compliance with the grounded theory approach. Through these interviews the process of choosing the secondary school and the relationship to the chosen school is described. In this part also the data from OECD PISA 2012 are used to provide an additional context. It is argued that the choice done by the apprentices is significantly limited and that the main source of such limits is social. These conclusions are connected with overall context of the Czech highly differentiated educational system. Keywords (in English) education, qualitative research, apprenticeship training, vocational education, choice of a secondary school, relationship to the school

The multi-year gymnasium is a part of the Czech educational system for the long time. Those gymnasiums are one of the most discussed institutions in terms of usefulness. Various studies are made in dependence on that trying to find reasons for choosing multi-year gymnasiums (as thesis "Why Do Primary School Children Choose Multi-year Gymnasiums?", which preceded this work). The aim of this diploma thesis is already the next step: figuring out, if gymnasium met pupils' expectations, and also to receive feedback and evaluation of their parents. It focuses on pupils' academic self-concept, on problems associated with transfer to multi-year gymnasium and on positives, which the pupils would not probably meet at elementary school with.
