Thermodynamic modelling of hydrogen fuel cells
Nováček, Marek ; Pavelka, Michal (advisor) ; Němec, Tomáš (referee)
In this thesis, proton exchange membrane fuel cells are studied. At the beginning, the ideas underlying their function are exposed and some possibilities of usage are pre- sented. Thereafter, we aim to describe the processes inside the fuel cells with the aid of thermodynamics and in agreement with constitutive relations that have been obtained experimentally. Namely, we are interested in the fluxes of water and protons inside the membrane, where they are acted upon by thermodynamic forces, and the electrochemical reactions at the electrodes, which can be described by the Butler-Volmer equations. Also do we study the efficiency of the fuel cell by evaluating the production of entropy due to the diverse processes that take place in the fuel cell. It is the goal of the computational part of this thesis to propose a zero-dimensional model and compare it with the results provided in the supervisor's doctoral thesis. 1

Günter Grass - Politic of iterature
Králová, Marie ; Kubíček, Tomáš (advisor) ; Peterka, Josef (referee)
The thesis deals with prose Peeling the onion written by a German author Günter Grass and with responses to this novel. Controversial moments of Grass's life which were never reported before are revealed in this commemorative literary work. It has evoked very contradictory reactions worldwide. The object of the thesis is to monitor the work in a broader social context and to reveal its controversy through the public reactions. Attention is also given to the literary analysis of the commemorative book. The aim of the thesis is to provide a very comprehensive view on this novel of Günther Grass, a political writer.

Brand engagement on social media: Case study of intercultural raction comparison to commercial media content of Purina brands
Kubínová, Monika ; Zezulková, Markéta (advisor) ; Lütke Notarp, Ulrike (referee)
The aim of this thesis is to understand how the same marketing media content affects audiences of different cultures. Many global brands are managed centrally with unified marketing communication shared across the nations. Content relevance is tested abroad and may not be relevant to all countries where the communication is published. McQuail in his book Introduction to Mass Communication, mentions that different cultures accept the same media content with different effects. I will use a case study for the analysis of intercultural communication of centrally managed brands that will examine the difference in responses of Facebook users to centrally created marketing communication of the Felix and ProPlan brands that belong under the umbrella brand Purina. I divided the case study into two parts, the first part will be devoted to the content analysis of documents, statistics and already existing research from which I formulated research questions. The second part is a semiotic analysis of comments of the Facebook users to the Purina brands that is answering the research questions. The data from the comments shows that the reactivity within the two countries studied differed significantly and depended on the cultural differences defined by Hofstede's cultural comparison. Based on this case study, it...

Presidents at war with media - paralels in media attitude towards presidents in USA and the Czech Republic
Pešková, Iva ; Miessler, Jan (advisor) ; Cebe, Jan (referee)
The aim of this thesis is to look for paralels in reactions and attitudes of Czech and American media towards offensive statements of presidents of the Czech Republic and USA with the focus on mainstream media. In a theoretical part of the thesis the role and function of media in liberal democracies are defined. Following part describes an actual media landscapes of USA and the Czech Republic. The main part - research, is based on the description of the media landscapes in both countries and analyzes the media reactions and attitudes towards one specific presidential statement (one by US president Donald Trump, one by Czech president Milos Zeman). Each statement had to be at most critical, attacking the media and had to raise high media response. Media reactions were afterwards analyzed using qualitative content analysis according to the principles of grounded theory. In the conclusion the categories given by the analysis are being compared and analyzed.

Factors influencing customer experience in context of new format retail stores
Brišová, Jana ; Koudelková, Petra (advisor) ; Jesenský, Daniel (referee)
The bachelor thesis "Factors influencing customer experience in context of new format retail stores" is focused on in-store customer experience phenomenon and on factors companies use in order to influence customers' purchasing behaviour and their decision-making pro- cesses. The theoretical part of the thesis explores, reviews and presents the theory on customer experi- ence, customer experience management, in-store customer experience and customer's internal responses to the marketing stimuli (cognitive, affective and physical) and customer's social interactions with other actors present in the retail store. By conducting a survey in a chosen new format retail store, the empirical part of the bachelor thesis then reviews the situation on the Czech market. It examines reactions, emotions, sensations and attitudes towards the retail shop- ping environment and subsequently analyses whether customer's loyalty is influenced by the character of those reactions.

Amphiphilic Dendritic Compounds as Drug Delivery Systems.
Edr, Antonín
To enable an easy detection of supramolecular objects assembled from 1 or 2, I am currently working on preparation of their unsymmetrical analogues 3 and 4 bearing a fluorescent tag. Final liposomes or micelles will be prepared from mixtures of fluorescent and nonfluorescent analogues.\n

Cognitive functions and performance in MMA
Toman, Karel ; Mudrák, Jiří (advisor) ; Pavelka, Radim (referee)
Title: Cognitive functions and performance in MMA Objectives: The goal of the work was to figure out the effect of cognitive functions to performance in MMA. Methods: Vienna test system, determination test Results: Research compares sample reactions to acoustic and visual impulses among three groups - professional MMA fighters, amateur MMA fighters and intact population. The results of the research show that MMA individuals, regardless of the category (professional and amateur MMA fighters), have better results than recreational athletes from the intact population. There were no significant differences among the group of professional MMA fighters and the group of amateur MMA fighters. Keywords: stress, reactions, Mixed Martial Arts, cognitive functions
