Sobotová, Kateřina ; Ducháčková, Eva (advisor) ; Oborilová, Mária (referee)
This bachelor thesis deals with insurance of tour operators. At the beginning are characterized differences between tour operators and travel agents that have to be distinguished for this insurance product. The second chapter focuses on development of tour operators insurance in the Czech Republic. There is described the legislative process of the law 159/1999 Sb and its amendment about some conditions of entrepreneurship in the field of tourism. There are also specified conditions for gaining and sustaining guarantee insurance in case of tour operator bankruptcy. A part of the chapter is devoted to the bank guarantee and the state supervision. The next chapter provides an overview of insurance companies that offer this type of insurance. Last two chapters are more practical. One of them analyses the amendment of the law 159/1999 Sb. issued on 1 January 2016. There are summarized reasons of this amendment and comparison of the law before and after the amendment. The other practical chapter describes the reasons of bankruptcy of tour operator called Marine Tour and the procedure in case of tour operator bankruptcy.

Monolayers of platinum nanoparticles prepared by dip-coating
Černohorský, Ondřej ; Grym, Jan ; Yatskiv, Roman ; Pham, V.H. ; Hudry, D. ; Dickerson, J.H.
Platinum is a transition metal known for its catalytic properties, which are further enhanced when employed in a nanoparticle form. We have recently shown that a monolayer of Pt nanoparticles deposited on semiconductor substrates forms high quality Schottky diodes, which were used in sensitive hydrogen sensors with a detection limit of 1 ppm of H-2 in N-2. Preparation of ordered monolayers of Pt nanoparticles is essential for the understanding of the behaviour of such an interface. To obtain a hexagonal closed-packed nanoparticle array, we prepared Pt nanoparticles stabilized by oleylamine and oleic acid with a narrow size distribution and uniform shapes. A monolayer prepared by dip-coating of Si substrate in the suspension containing Pt nanoparticles showed hexagonal arrangement within separate domains with the surface coverage up to 90%. The increase of the surface coverage with increasing withdrawal speed of the dip-coating process was observed

THE EFFECTS OF HIGH TEMPERATURE HELIUM GAS ON THE FRACTURE BEHAVIOUR OF ODS MA957
Rozumová, L. ; Hojná, A. ; Kalivodová, J. ; Bublíková, P. ; Hadraba, Hynek ; Di Gabriele, F.
Oxide-dispersion-strengthened steel (ODS) MA957 has been studied as a candidate material for Tritium Breeding Blanket for fusion reactors with helium coolant, where temperatures 250-650 degrees C are expected. Helium is one of type as primary coolant in High Temperature Reactor and Gas Cooled Fast Reactor with working temperature 500-1000 degrees C. \n\nThis work presents results of the study of behaviour of ODS (MA957) under influence of high temperature helium environment. Microstructure of the material and the interaction with He was investigated. The average exposure temperature was held at 720 degrees C. Subsequently, the surface changes were determined. Impact testing and material surfaces were studied in detail by means of SEM and TEM microscopy. It is essential to understand the He effect on microstructure and mechanical properties of structural materials since the He embrittlement in TBB may be significant.

Biochemical methods as tool for study of reproductive proteins
Postlerová, Pavla ; Zigo, Michal ; Pohlová, Alžběta ; Jonáková, Věra
Study of molecular mechanisms in reproduction is essential for the understanding of this outstanding process. Our lab studies proteins secreted by reproductive organs and sperm using various biochemical methods for a long time. We have expertise in protein extraction from spermatic cells using different approaches, and by kits for proteins from the sperm surface and distinct subcellular compartments. The proteins of reproductive organ fluids are separated by chromatographic methods, such as size exclusion chromatography, high-performance liquid chromatography with reverse phase (RP-HPLC) and affinity chromatography on matrices with various ligands. Proteins are subjected to SDS- or 2D-electrophoresis for their characterization and comparison of various extraction methods, different mammalian species, and sperm in different functional development. Electrophoretically separated proteins may be transferred onto nitrocellulose membrane (Western blot) for antibody detection or binding studies with lectin-labelled ligands (lectins, polysaccharides, zona pellucida glycoproteins). We use immunoprecipitation method with specific antibody for protein determination followed by the MALDI identification. Proteins are localized by immunofluorescent techniques on/in spermatic cells and tissue sections of reproductive organs. Isolation of proteins from reproductive tissues and fluids, and the antibody detection is crucial for the studying of reproductive protein origin.

Fracture Behaviour of Steels and Their Welds for Power Industry
Al Khaddour, Samer ; Kohout, Jan (referee) ; Válka, Libor (referee) ; Dlouhý, Ivo (advisor)
Práce byla zaměřena na ověření platnosti koncepce master křivky pro hodnocení heterogenních svarových spojů, resp. teplotně stárnutých svarů. Současně bylo cílem disertace vyvinout kvantitativní model pro predikci referenční teploty lokalizující tranzitní oblast na teplotní ose za použití dat získaných z tahové zkoušky, a to za použití metody umělých neuronových sítí. Studie je současně zaměřena na heterogenní svarový spoj připravený tavným svařováním. Je zacílena na hodnocení lomového chování v tranzitní oblasti nejméně odolné části svaru, tj. tepelně ovlivněné zóny ferritické oceli v blízkosti zóny natavení s vysokolegovaným materiálem. Pro predikci referenční teploty master křivky je použita zmíněná metoda neuronových sítí, a to za použití dat z tahových zkoušek a měření tvrdosti. Predikovaná referenční teplota byla ověřována na základě výsledku experimentálních měření. Vytvoření modelu za použití neuronových sítí vyžaduje dostatečné množství dat a není vždy snadno tuto podmínku splnit. V případě sledovaného problému to znamenalo použití dat z dostatečně věrohodných zdrojů (skupiny Křehký lom ÚFM AVČR) a se známou metalurgickou historií. Smysl práce je tak možno spatřovat ve vývoji modelu neuronové sítě, která bude dostatečně přesně predikovat referenční teplotu. Celkově byla pro tyto účely použita data z 29 nízkolegovaných ocelí. Pro účely vývoje byly použity kromě hladkých zkušebních tyčí, rovněž tahové zkoušky s obvodovým vrubem testované při kritické teplotě křehkosti (mez makroplastických deformací) a při teplotě pokojové. Při tvorbě modelu byla postupně v různých kombinacích využita všechna data z uvedených zkoušek. Studie ukázala, že referenční teplota charakterizující tranzitní chování lomové houževnatosti oceli s převažující feritickou strukturou je jedinečným parametrem predikovatelným na základě vybraných charakteristik tahových zkoušek.

Personal Charasteristics and Social Aspects in Some Social roles in Bullying
ŠTĚPNIČKOVÁ, Lucie
My diploma thesis deals with social support of chosen roles which occur while bullying the role of a victim and a defender. The diploma paper is divided into two consecutive parts a theoretical and a practical one. In the beginning of the theoretical part I introduced the problems of bullying and identified the roles which can be present while bullying. I also focused on the characteristics of terms: social support, capturing its forms, the participants of bullying and last, but not least the differences in children´s age. The practical part contains mixed (quantitative and qualitative) research methods. There are two goals of the research, the first is to reveal the potential roles of participants of bullying in a class team, and the second one is to detect the level of social support provided by teachers and classmates to defenders and victims of bullying. The qualitative research works as a supplement, it is focused to opinions and attitudes of defenders and victims considering the behaviour while bullying.
