Vlastnosti a zpracování masa nutrií
Hermanová, Nikola
The meat from nutrias is one of the possible variants how to make our menu more interesting. Nutria meat has realy high nutritional value, its composition is quite similar to well known rabbit meat. For a low fat and cholesterol content and high protein content the meat from nutrias is classified as dietetic and is recommended for a healthy diet. In relation to meat quality, there are important factors such as age, sex, nutrition, farming methods and colour type of nutria. Furthermore, physical properties such as pH, meat colour and oxidation stability. Nutrias are mostly home slaughtered on a farm. The slaughter consists of mechanical strike directed at the nape of nutria to stunt an animal and subsequent bleeding out. After slaughtering an animal usually follows skinning called "to the bag". Nutrias are farmed not only for a meat, but also for other valuable resources such as fur, teeth and skin of the tail.

Charge Carrier Transport in Ta2O5 Oxide Nanolayers with Application to the Tantalum Capacitors
Kopecký, Martin ; Koktavý, Bohumil (referee) ; Hudec, Lubomír (referee) ; Sedláková, Vlasta (advisor)
Studium transportu náboje v Ta2O5 oxidových nanovrstvách se zaměřuje především na objasnění vlivu defektů na vodivost těchto vrstev. Soustředíme se na studium oxidových nanovrstev Ta2O5 vytvořených pomocí anodické oxidace. Proces výroby Ta2O5 zahrnuje řadu parametrů, jež ovlivňují koncentraci defektů (oxidových vakancí) v této struktuře. Vrstva oxidu Ta2O5 o tloušťce 20 až 200 nm se často používá jako dielektrikum pro tantalové kondenzátory, které se staly nedílnou součástí elektrotechnického průmyslu. Kondenzátory s Ta2O5 dielektrickou vrstvou lze modelovat jako strukturu MIS (kov – izolant – polovodič). Anodu tvoří tantal s kovovou vodivostí, katodu potom MnO2 či vodivý polymer (CP), které jsou polovodiče. Hodnoty elektronových afinit, respektive výstupních prací, jednotlivých materiálů potom určují výšku potenciálových bariér vytvořených na rozhraních kov-izolant (M – I) a izolant-polovodič (I – S). Dominantní mechanizmy transportu náboje lze určit analýzou I-V charakteristiky zbytkového proudu. Dominantní mechanizmy transportu náboje izolační vrstvou jsou ohmický, Poole-Frenkelův, Shottkyho a tunelování. Uplatnění jednotlivých vodivostních mechanismů je závislé na teplotě a intenzitě elektrického pole v izolantu. Hodnota zbytkového proud je významným indikátorem kvality daného izolantu. Ten závisí na technologii výroby kondenzátoru, významně především na parametrech anodické oxidace a na materiálu katody. I-V charakteristiky zbytkového proudu se měří v normálním a reversním módu, tj. normální mód značí kladné napětí na anodě a reversní mód záporné napětí na anodě. I-V charakteristika je výrazně nesymetrická, a proto tyto kondenzátory musí být vhodně polarizovány. Nesymetrie I-V charakteristiky se snižuje s klesající teplotou, při teplotě pod 50 K a je možno některé kondenzátory používat jako bipolární součástky. Z analýzy I-V charakteristiky lze určit řadu parametrů, jako tloušťku izolační vrstvy a koncentraci defektů v izolační Ta2O5 vrstvě a dále lze odhadnout parametry MIS modelu kondenzátoru - stanovit hodnotu potenciálových bariér na rozhraních M – I a I – S. Měření C-V charakteristik při různých teplotách v rozsahu 10 až 300 K je využíto pro určení výšky potenciálové bariéry na rozhraní I – S, závislosti kapacity na teplotě a dále pro výpočet efektivní plochy elektrod. Z výbrusu vzorků na skenovacím elektronovém mikroskopu byly určeny tloušťky dielektrika Ta2O5 pro jednotlivé vyhodnocované řady kondenzátorů.

Importance of bank stress tests in response to financial crisis
Honcová, Eliška ; Blahová, Naděžda (advisor) ; Brada, Jaroslav (referee)
This thesis deals primarily with issues of stress testing the banking sector in response to the current financial crisis. The first chapter briefly describes the basic causes of the financial crisis and its impact on the banking sector and the subsequent expansion into the European Union. A brief description of selected accepted European regulatory and supervisory reforms is followed. Their content is related to the stress tests. The second chapter describes in detail both the original and current stress testing methodology and shows the development in testing, which passed just after the outbreak of financial crisis. The additional tests of banks and the subsequent verification of test results are an integral part of the chapter. A key part of this work is to analyze the stress tests in Europe and then in CR for the year 2011. Test scenarios and specific test results are described here. In conclusion, the work tries to evaluate the adjustment of the Czech stress tests and their explanatory value compared to the European tests.

Dynamic Elasticities of Tax Revenue: Evidence from the Czech Republic
Havránek, Tomáš ; Iršová, Zuzana ; Schwarz, Jiří
Tax revenue elasticities with respect to tax bases are key parameters for the modeling of public finances. Yet the existing studies estimating these elasticities for post-transition countries disregard the effects of tax reforms on tax revenue, which renders their estimates inconsistent. We use a unique data set from the Czech Republic to account for the effects of reforms and estimate both short- and long-run tax revenue elasticities. Our results suggest that the long-run elasticities are 1.4 for wage tax, 0.9 for value added tax, 1.7 for profit tax, and 1 for social security contributions. The adjustment process for value added tax and social security contributions is fast, but for the remaining two categories it is important to distinguish between the short- and long-run elasticities: the initial response of revenue to changes in the bases is weak. In the case of wage tax it takes half a year for the elasticity to surpass unity.

Study of light microclimate in a chosen vegetation type during vegetation season
STOLIČKOVÁ, Martina
The aim of Bachelor thesis is the analysis of light microclimate depending on the production profile of sedge vegetation ( Carex acuta L. ) during the growing season. The light transmission of the growth of sedge and its changes during the growing season were examined. Then the seasonal cycle of the incoming and reflected solar radiation, including the albedo was evaluated.The seasonal changes in increase of aboveground live biomass, the amount of dry matter in the vertical vegetation profile, the distribution of leaf covering and the extinction coefficient changes during the growing season were assessed. The study of light microclimate and the biomass sampling was conducted in Mokré Louky near Třeboň close to pond Rožmberk. The largest representation of plant species has got Slender sedge ? Carex acuta L. there. The findings of relative insolation and light transmission was measured by pyranometer and the sampling of aboveground part was conducted by destructive method. These results show that the transmission is the highest at the vegetation surface and it decreases with the declining height. In August there was a radical decrease in the impact and the reflection of solar radiation due to the higher concentracion of water in the soil and air and this led to a reduction in albedo. Live biomass was measured: in July 1820g, in August 1670g and in September 1789g.The values of LAI and dry matter, recorded from July to September,were gradually decreasing and with the growing measured layer of growth there was a reduction in amount of dry matter and value of leaf area index.The extinction coefficient value varies depending on the age of stand. With the vegetation age the extintion coefficient increased up to 200,38. The Bachelor Thesis was developed within the research project of Faculty of Agriculture MSM 6007665806 ? The sustainable methods of farming in the foothills and mountainous areas,aiming to create harmony between their production and non-production application?.

Superparamagnetic nano- and microparticles with hydrophilic surfaces
Babič, Michal ; Horák, Daniel (advisor) ; Šňupárek, Jaromír (referee) ; Šafařík, Ivo (referee)
This work deals with a preparation of superparamagnetic nano- and microparticles with hydrophilic surfaces for bioapplications. The wok is divided into three parts in consonance with experimentally solved problem. First part describes a choice and an optimalization of synthesis of iron oxides nanoparticles with appropriate toxicological, morphological and physico-chemical properties, which surface can be post synthetically modified. Maghemite - γ-Fe2O3 particles were prepared by consequent oxidation of mangnetite - Fe3O4 as an initial substance for a preparation of materials for diagnostics and separations. A conventional alkaline coprecipitation method of magnetite preparation was modified to produce nanoparticles with narrowed size distribution without use of surfactants during their synthesis. Prepared maghemite nanoparticles were cca. 6 nm in diameter and their saturation magnetization was Ms ~ 70 A·m2 ·kg-1 . Such observed value is far higher in comparison with the state of the art and argues thus a proposition the Ms depends not on the preparation method, but only on the nanoparticles size. Maghemite nanoparticles morphology was evaluated by picture analysis of SEM and TEM micrographs, hydrodynamic size and zetapotential was measured with DLS. The structure of the maghemite was confirmed with...

Troubles on stage: theatrical representation of the conflict in Northern Ireland
Kristenová, Lenka ; Pilný, Ondřej (advisor) ; Wallace, Clare (referee)
The objective of this thesis was to provide a detailed analysis of three modern Irish plays which share one common feature - the portrayal of the conflict in Northern Ireland. Apart from the common background of the Troubles, the plays focus on different aspects of the conflict which also demands different theatrical design. Furthermore, each play was analysed from three social perspectives - religion, gender and locale - in order to examine the ways in which these notions were influenced by the conflict as well as on the ways in which this influence is manifested on individual people. Attached to each play are short conclusions to their respective analyses. Despite their difference, the analyses of the plays also revealed several interesting similarities. Firstly, in the issue of gender, there is a certain discrepancy between the officially proclaimed and recognised division of gender roles and the reality of everyday life. Whereas officially the women are in an inferior position to men, and are expected to be an element of passivity, the three plays suggest that it is rather the men who represent passivity. The plays also point out how the position of men and women in society is further determined by the sectarian conflict. In all three plays, women prove to have stronger characters than men: in Tea in a...

Structural study of metal-CeO2/Cu(111) model systems by RHEED
Beran, Jan ; Mašek, Karel (advisor) ; Jiříček, Petr (referee)
The cerium oxide was deposited by reactive vacuum evaporation on the (111) surface of copper single-crystal in oxygen atmosphere at constant substrate temperatures of 25řC, 300řC and 450řC and at increasing temperature from 25řC to 450řC. In each case, the cerium oxide grew epitaxially with the (111) plane parallel to the substrate. The lattice parameter of the oxide increased up to the value of 5,28 during the deposition. At increasing temperature the growth of additional three-dimensional domains with tetrafold symmetry and (100) plane parallel to the surface was observed. Lattice parameter of these domains exhibited the value of 5,36 in the direction parallel to the surface. These domains were also observed by STM. The palladium grew on the cerium oxide surface in form of epitaxial islands having (111) epitaxial plane parallel to the substrate surface. The palladium deposition resulted in the partial reduction of the oxide layer. The reduction was caused by the interaction of the palladium and oxygen atoms leading to the formation of PdO phase. This feature became more pronounced during annealing at 300řC. Annealing at higher temperatures led to coalescence of the palladium islands and thermal induced decomposition of the palladium oxide.

Low EV/EBITDA multiple: inefficient market or a hidden potential for Fortuna Entertainment Group?
Bochkareva, Ekaterina ; Strouhal, Jiří (advisor) ; Strnad, Martin (referee)
This thesis was initiated by Penta Investment as a reaction on the significant difference in EV EBITDA multiple of Fortuna and its peers, European listed betting and gaming companies. It seeks to find the reason for more than twice higher multiple and a possibility to increase it by applying best international practices in case there is a feasible way to do it for Fortuna. Three hypotheses address the possible reasons for the difference, peers incomparability, market inefficiency and opportunity for Fortuna to increase the multiple by bringing the most influential KPIs the average level of its peers. The analysis is done with a help of comparative analysis, benchmarking, regression analysis and interviews of equity analysts. As a result, action plan for increasing EV EBITDA multiple for Fortuna is developed.
