Determination of selected metals in soils and mushrooms in the vicinity of the D1 highway.
HORÁKOVÁ, Tereza
The aim of the bachelor thesis was to determine the concentrations of heavy metals in edible mushroom samples and underlying soils. The elements measured were mainly copper, iron and zinc, followed by manganese, strontium and rubidium. The literature search contains brief information on each element and their content in soils and fruiting bodies of mushrooms in other studies. The theoretical part also includes chapters on fungi, soils and their contamination, the effect of vehicular traffic on the heavy metal content of soils and the used analytical method, which was atomic absorption spectrometry. For the practical part, 24 samples of eight different species of edible mushrooms were collected in the autumn of 2020 and 2021 in the vicinity of the D1 motorway. As part of the collection, the soil beneath the mushroom was also sampled to a depth of approximately 15 cm. The samples were first perfectly dried, then processed by microwave digestion, and finally analysed by AAS. All work was carried out in the laboratories of the Department of Applied Chemistry, Faculty of Agriculture and Technology, University of South Bohemia in České Budějovice. The results of the measurements were tabulated and processed statistically and graphically. Finally, they were evaluated in a discussion. The analysis showed that birch and birch goosefoot accumulate the least heavy metals in their fruiting bodies. The spruce budworm, the pink toadflax, the celandine and the brown mushroom accumulate metals on a large scale. In total, 4.2-45 mg.kg-1 dry weight Cu, 97,4-4166 mg.kg-1 Fe, 52,1-338,7 mg.kg-1 Zn, 3-61,4 mg.kg-1 Mn, 1,3-7 mg.kg-1 Sr and 7,7-300,9 mg.kg-1 Rb were measured in mushrooms. In soils, the values were as follows: 5,2-78,6 mg.kg-1 Cu, 2 965-41 983 mg.kg-1 Fe, 25,8- 174,2 mg.kg-1 Zn, 49,7-1 868 mg.kg-1 Mn, 6,2-25,2 mg.kg-1 Sr and 12,2-114,5 mg.kg-1 Rb in dry weight. These results show that strontium was the least represented heavy metal studied and iron was the most represented.

Integration of Financial Markets
Horáková, Tereza ; Horváth, Roman (advisor) ; Chalupka, Radovan (referee)
In our thesis we offer an empirical analysis of relations between financial markets of the Czech Republic and the Euro area countries in the period between 1999 and 2008. We use the theoretical background of financial integration and existing research findings on it as groundwork for our analysis. In our empirical analysis we examine the similarities in volatility behavior and possible volatility transmissions to offer an additional perspective on the financial market interdependencies. Our methodology is based on the GARCH family of models that we use to assess the pattern and relationships between the conditional volatilities in the foreign exchange, equities and bond markets. Results of our empirical analysis did not allow us in most cases to conclude on significant volatility spillovers and therefore to confirm our hypothesis, which we formulated as existence of significant relationships between the Czech and Euro area financial markets in terms of their volatilities. However we believe that the indications that we have presented bring some additional insights on the interdependencies between the Czech and Euro area financial markets and their evolution over the past years. The correlations between the fluctuations indicate the strongest degree of interrelatedness in the foreign exchange market.

Zásady reprodukce savců chovaných v zoologických zahradách
Horáková, Tereza
This work on the Principle of reproduction of mammals bred in zoos has been developed as a bachelor thesis at Mendel university in Brno and deals with the selected mammal species, that we commonly see in our zoos. The work is divided into several parts - the general principles of the reproduction of mammals, tracking, and monitoring of reproductive status, reproductive biotechnology and the reproduction of bears is described in more detail. The first part describes the reproduction physiology, which includes the neurohumoral activity and the sexual cycle of mammals; and anatomy of the reproductive systems of males and females, where are described all the morphological differences between the different groups of animals. In the second part I looked at the possibilities of reproductive status monitoring when we can monitor external signs, use ultrasonography or control reproductive hor-mones. In the third part are described the basic reproductive biotechnology, which can be used in the reproduction of mammals. This is all about artificial insemination, in vitro fertilization, embryotransfer and cloning. In the last part, the reproduction in bears is described in more detail. It shows the preparation of animals for the reproductive period, starting their sexual behavior. It also describes the procedure for the use of natural breeding, reproductive biotechnics, methods of diagnosis of pregnancy, their birth, care of young animals and rearing within the Czech Republic and the world.

Diminutive and augmentative suffixes in portuguese
Horáková, Tereza ; Svobodová, Petra (advisor) ; Hricsina, Jan (referee)
The aim of this diploma thesis is to prove that augmentative and diminutive suffixes are not always just bearers of senses "big" / "of big size", in the case of augmentative suffixes, and "small" / "of small size", in the case of diminutive suffixes, and that they can also be accompanied by various connotations. The thesis is divided into several parts. The first part is concentrated on the topic of the morpheme in Portuguese in general. The next two parts are dedicated to particular augmentative and diminutive suffixes, concretely to their origin and especially to their specifics. Fundamental is the last part which focuses on the systematization of the senses of suffixes mentioned in previous chapters. Key words: word-formation, derivation, suffixes, augmentative suffixes, diminutive suffixes, connotation

Fair and Equitable Treatment and Legitimate Expectations in Investment Disputes
Horáková, Tereza ; Balaš, Vladimír (advisor) ; Trapl, Vojtěch (referee)
The concept of legitimate expectations plays a significant role in international investment law. Although it is only in the past roughly fifteen years that the concept has come to the spotlight, its importance and utilization is on the rise. Generally speaking, the concept of legitimate expectations, under certain conditions, allows a foreign investor to claim compensation in situations where the conduct of a host State creates a legitimate and reasonable expectation that the investor may rely on such conduct, and consequently the host State fails to fulfill those expectations, causing damages to the investor. However, the concept of protection of legitimate expectations has stirred up debates as to the legitimacy of its use in investment law and raised concerns due to its imprecise boundaries and excessively extensive interpretation. Accordingly, it is the goal of this thesis to either confirm or refute two main propositions. The first proposition suggests that the principle of protection of legitimate expectations is an established principle of investment law with traceable origins in both domestic law and general international law. The examination of the first proposition addresses theoretical roots of the concept of legitimate expectations justifying its application in investment law together...
