Memes and the Theory of Universal Darwinism
Havlík, Vladimír
The article deals with the philosophical presuppositions and groundwork of the memetics. The central question is an analysis of Universal Darwinism as a common and universal evolutional principle or pattern that always springs in every environment when there're fulfilled required conditions. An evolutional process could be possibly described like an algorithmic process that faces to the rise of organized orderliness. Darwinism in this generally universal sense points to a distinctness survival of any kind self replicated code of information that has some influence over its probability of replication. The article stresses methodological importance of memetics as it makes possible to introspect variety of cultural development from a simple unification perspective.

Trasfer Heat Analysis in Steam Generators in blocks of VVER 440
Roupec, Petr ; Pulec, Jiří (referee) ; Šen, Hugo (advisor)
The aim of this thesis is to analyze the heat transfer in steam generator of blocks in the nuclear power plant VVER 440. The steam generator represents the border between the primary and the secondary circuit. The heat is carried from a warm water from reactor to a cold water. The steam arises after the heat transfer and drives the steam turbine. An important quantity which represents the heat transfer is a heat transfer factor. This thesis is divided into theoretical and a practical part. In the theoretical part is mentioned a principle of the steam generator and the theoretical calculation of the heat transfer factor, which comes first of all from the character of the streaming in the steam generator. The practical part brings a comparison of the heat transfer factor calculated from data measured after the start of the third block of EDU in 1986, with the heat transfer factor which comes from the measurement after the power-increase for 105 % of nominal power of the same block in 2009. Further is shown the prediction of the heat transfer factor for next power-increase and the following service is shown too.

The Controlling Study
Herda, Tomáš ; Mikovcová, Hana (advisor) ; Herda, Zdeněk (referee)
The main goal of this Diploma´s Thesis is to make a model for calculation of water and sewer rates for the company Vodovody a kanalizace Náchod, a.s. when sticking to the set criteria both from the side of VaK Náchod, a.s. and law regulations. Based on the theoretical part an analysis of customer sensitivity to the price changes using the data for last 20 years follows. Findings from the first two parts are used in risk analysis in next part. The created model calculates the water and sewer rates based on the information from the company accounting system in the way to generate sufficient financial resources to fulfill the renovation plan of infrastructural property plant and equipment and to transfer given amount to the company funds. In addition, the model monitors whether the legal condition of maximal allowable increase of profit per m3 is met. In the customer sensitivity to the price changes part the price elasticity of demand for water and sewer rates is calculated based on the data from 1995 to 2015. The assumption of inelastic demand is confirmed. Risk analysis part is deals with potential risk regarding the demand and prices. Potential impacts for the most significant risk are quantified. The analysis uses knowledge gained in the first two parts. It was confirmed that potential risks are exiting but do not have any significant impact on the going concern of VaK Náchod, a.s. The created model has been already used for the calculation of prices for the year 2017. Customer sensitivity analysis to the price changes and link to the potential risks is an additional information for VaK Náchod, a.s. which validates that nowadays, there are no significant threats which could affect the demand and water and sewer rates significantly.

A manuscript of Italian monody from the Lobkowicz library
Kadeřábková Tašnerová, Helena ; Daněk, Petr (advisor) ; Maňourová, Lucie (referee)
Mgr. Helena Kadeřábková Tašnerová A manuscript of italian monody from the Lobkowicz library Edition of compositions included in the manuscript collection of Italian monody in the Roudnice Lobkowicz Library in Nelahozeves under signature II La 2 is the main subject of the thesis. Internal and external description of the manuscript is provided as well as analysis of its music and lyrics contents, information about the composition authors and about possible ways of this source to the Czech collection funds. Considerable attention is also paid to Bologna manuscript Q 49 closely relating to this Lobkowicz one. Their main conformities and contradictions are defined. Comparison of the two manuscripts succeeded in determining authorship of some anonymous compositions, and on the contrary, authorship of other ones was doubted. On the basis of some common filigrees that were found, it was verified that the manuscripts are of the same provenience. Clearly arranged tables comparing the two manuscripts follow, along with the redrawn filigrees, editions of all manuscript compositions and separate edition of all composition lyrics. This is the first so coherent treatment of this resource.

Contributions to Volatile Compound Generation of Arsenic, Silver and
Musil, Stanislav
(EN) The presented dissertation thesis summarizes the results contained in five original research papers that were published in prestigious international scientific journals in the field of analytical chemistry and atomic spectrometry. It is devoted to the method of generation of volatile compounds using a tetrahydroborate reaction and detection in a quartz multiatomizer by atomic absorption spectrometry. The thesis can be divided into two thematic parts - speciation analysis of arsenic based on hydride generation technique with collection and separation in a cryogenic trap and generation of volatile species of transition metals. In the first thematic part pre-reduction of pentavalent inorganic and methylated arsenicals has been studied. A simple setup for on-line pre-reduction employing thioglycolic acid as a fast pre-reductant has been developed, connected with a current hydride generator and applied/verified to oxidation state specific arsenic speciation analysis of human urine samples. In the same method the possibility of drying the gaseous phase from water vapor has been investigated to avoid incidental blocking the cryogenic trap by frozen water and to decrease fluctuations of signal baseline. Pronounced losses of methylated species have been discovered on Nafion tube dryer currently used in...
