Socio-cultural centre with townhall for the district Brno-Kohoutovice
Ľuptáková, Lenka ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
The building of the town hall Brno Kohoutovice is situated on the site next to the local hospital. Currently, there is a widespread paved area, which has become the place for markets and other cultural activities. Town hall completed urban structure, built on the most visible plot, and closes the plaza on the east side. From the south, the square is open to Kohoutovická valley. It is closed and opened at the same time by a colonnade. Functional composition is expressed in both - size and material. On a solid concrete base, which holds cultural and social events, lie two light steel boxes dedicated to the town hall. The middle part is cantilivered into the square, which symbolizes the proximity of town hall offices to the citizens. It is dedicated to the departements, which are in daily contact with the public. The upper part with large terrace has representative function. There are the internal departements and a ceremonial hall.

Optimization of optical and transport properties of PVA based hydrogels
Zahrádka, Jan ; Kalina, Michal (referee) ; Sedláček, Petr (advisor)
The main goal of this bachelor thesis is to design and optimize a suitable method for preparation of transparent physically crosslinked hydrogels with manipulable transport properties. Polyvinyl alcohol (PVA) crosslinked by cyclic freezing and thawing was chosen as the model gel-forming material. From the originally proposed three mechanisms of influencing optical properties of thus prepared PVA gels, the influence of freezing rate was selected on the basis of pilot screening experiments for a deeper follow-up analysis. The mechanical properties of prepared hydrogels were analyzed by rheology using strain sweep test. The internal structure was visualized by scanning electron microscopy (SEM). The optimized technique for preparation of transparent PVA gels was subsequently used for preparation of gels with an interpenetrated polyelectrolyte component (poly (styrene sulfonate)). It was then experimentally verified by diffusion pair method with methylene blue as diffusion probe that the hybrid hydrogel network has modified transport properties.

Processing of compact polycrystalline YAG ceramics
Kaplan, Lukáš ; Pouchlý, Václav (referee) ; Kachlík, Martin (advisor)
In the literary part of this master thesis a research on various methods of preparation of dense polycrystalline YAG ceramics and the effects of sintering on the densification and other desired properties of such prepared YAG ceramics was carried out, the transparency after addition of dopant elements was also discussed. In the experimental part of the thesis, samples of dense polycrystalline YAG ceramics were prepared by SSR method and the effect of sintering on the densification and porosity of the YAG ceramic samples was studied. Relative density, porosity, phase purity and transparency were measured on the sintered samples. These measurements were compared with the results of the works reported in the literature section.

Sprayable elastic biopolymer hydrogels for wound healing
Waclawiková, Petra ; Nedomová, Eva (referee) ; Vojtová, Lucy (advisor)
Cíle prezentované bakalářské práce jsou zamšřeny na přípravu a charakteristiku sprejovatelných hydrogelů z vhodných netoxických látek, za účelem vyvinutí gelů aplikovatelných pro řízené hojení ran. Teoretická část se zabývá obecnými vlastnostmi hydrogelů, způsoby jejich síťování, a uvádí vybrané přírodní a syntetické materiály používané pro přípravu hydrogelů. Obsahuje také krátký přehled již připravených sprejovatelných hydrogelů, které ale zatím nejsou komerčně využívány. Experimentální část popisuje výběr a použití lehce dostupných netoxických materiálů a měření chemicko-fyzikálních vlastností z nich připravených gelů. Jako strukturní polymery byly zvoleny gum Karaya, poly(vinyl alcohol) a alginát sodný společně s různými fyzikálními síťovadly a aditivy. Polymery včetně aditiv byly podrobeny zkouškám rozpustnosti, a v určitých poměrech byly smíchány a následně síťovány za tvorby přednostně transparentních hydrogelů. Poté byly vyhodnoceny jejich optické a reologické vlastnosti. Z měření optických vlastností vyplývá, že gum Karaya ovlivňuje růst jak žlutosti, tak i transparentnosti připravených hydrogelů. Reologické měření prokázalo že vyšší obsah polysacharidu gum Karaya snižuje mechanickou odolnost připravených hydrogelů. Tuhost hydrogelů byla ovlivněna jak nízkou tak i vysokou koncentrací síťovadla, kde optimální množství vykázalo nejlepší výsledky. Správný poměr a dávkování použitých látek jsou tedy hlavními parametry pro získání nejvhodnějších vlastností hydrogelů pro sprejovatelné obvazy na hojení ran.

Socio-cultural centre with townhall for the district Brno-Kohoutovice
Valošková, Tereza ; Pechman, Tomáš (referee) ; Sochor, Jan (advisor)
From a theoretical perspective, concept of City Hall building is built on three values: openness, transparency and community support. I understand these values at two perspektive: literally, as access to buildings not only in the opening hours of the town hall, and figuratively, as openness to other than bureaucratic functions. Town Hall should also promote cohesion and dynamism of the local community. Not just a casual setting where people spend just a neccesary time, but a space where people will want to delay a meeting. The value of transparency in my political and social environment is essential. Town Hall can, and should, give citizens view into the working space officials, as well they should not be cut off from events in the city. Flow of information to and perceptions can be beneficial for both sides.

Accountability of international NGOs
Staša, Michal ; Skovajsa, Marek (advisor) ; Muhič Dizdarevič, Selma (referee)
Diploma thesis concerns two current issues filling scholarly magazines in recent years. The first one is a discourse about the global civil society, its existence, definition and scope. Thesis maps the basic approaches and creates three groups of authors: globalists, skeptics and empiricists. The second issue is about the need of better accountability which arises after few scandals of global institutions in the early years of new century. The scandals didn't avoid the international non-governmental organizations. The diploma thesis summarizes few types of typologies of accountability and introduces the basic areas divided into the two groups: moral and political accountability and procedural and internal accountability. The research part of thesis comprises the accountability assessment of three branches of international non-governmental organizations: Amnesty International, Greenpeace and Hnutí DUHA - The Friends of the Earth. The goal was to find the appropriate methodology for assessing the national branches and verify it. The main result is the modification of an existing methodology of One World Trust organization and the finding that the organizations have the low rate of accountability.

Anonymous Private Party Funding in Denmark: How do journalists cover this issue?
Merved, August Kaae ; Shavit, Anna (advisor) ; Turková, Kateřina (referee)
This thesis intends to examine the amount- and reasons for the news coverage related to the controversial party funding system in Denmark. This is achieved through comparisons of other political cases during the Danish 2022 and 2019 elections in a quantitative media analysis. The results are then analyzed and discussed using the data from eight interviewed Danish journalists working on some of the seven most prominent Danish media outlets. These qualitative interview data provide insights into reasons, motives, and causes for the fluctuation and difference in the coverage between the other observed and analyzed political cases in the past two elections. The findings show that the journalists deem party funding a complex and technical subject, but still, a subject deemed important to cover by journalists. However, in a fast-paced news agenda, the non-transparent party funding is covered less in comparison with news topics or cases during elections that are more emotionally charged and personalized, or topics that can provide a more direct influence on society, according to the qualitative data - as opposed to the more complex cases of political funding.
