Optimization of hydrogel carrier for assessment of antimicrobial activity of biocidal surfaces
Antálek, Adam ; Jančovičová, Viera (referee) ; Králová, Marcela (advisor)
This diploma thesis deals with the optimization of the composition and properties of hydrogels as carriers of microbial populations for the evaluation of the antimicrobial effects. There are standardized procedures for assessing antimicrobial surfaces, but they have shortcomings, such as the necessity of testing exclusively under laboratory conditions. In the presented work, a new evaluation methodology is proposed, which utilizes a modified resazurin test and hydrogels as platforms for bacterial seeding, enabling the assessment of the investigated antimicrobial surface. The composition and properties of hydrogel carriers were successfully optimized with respect to their swelling and mechanical properties, thereby improving recovery compared to standardized procedures. Tests on antimicrobial materials showed that the bacteria used on hydrogels continued to grow, rendering the use of composite hydrogels for this application impractical.

Deformation Surveying of Bridge Abutment and Top of Earth Fill
Malota, Matěj ; Kuruc, Michal (referee) ; Švábenský, Otakar (advisor)
The subject of my bachelor´s thesis is shift observation of abutment and the top of earth fill at western side of the Ivančice viaduct. It is unstable due to complicatedhydro-geological conditions while merging the abutment and the adjacent, 23 metres high slope of embankment.In my thesisI am processing previous periods of GPS monitoring, which were measured since spring 2000 to autumn 2009, and also two of my own measured periods at spring 2012 and 2013.
