Analysis of trace pollutants in water and their photocatalytic degradation
Štěpánková, Sandra ; Rathouský, Jiří (advisor) ; Nesměrák, Karel (referee)
Mesoporous TiO2 films with variable thickness were prepared by dip-coating. Two kinds of sols were used, sol 1 and sol 2, which were separately tested and compared. The activity of samples of these sols was tested employing photocatalytic degradation of 1.10-4 mol.dm-3 4-chlorphenol. The efficiency of the degradation of 4-chlorphenol was increasing proportionately with each additional layer. The optimum turned out to be three layers.

Barvínková, Tereza ; Pátková, Jana (advisor) ; Chmel, Rudolf (referee)
The thesis is of an analytical/interpretative character, focusing on paradigmatic analysis of the motives, images, symbols and allusions in the works of Slovak novelist Stanislav Rakús. The object of the analysis is the short story collection Pieseň o studničnej vode, first published in 1979. The multilayeredness of Rakús's texts urges the reader to search for different interpretative possibilities. The language of images, symbols and allusions affects not only the motivic and expressive structure of the text, but also e.g. the temporal and spatial identification of the stories, and in a specific manner it also affects the narrative situation implied. The thesis focuses on detailed analysis of individual layers of the literary texts.

Darmovzalová, Marie ; Komínková, Dana (advisor) ; Hořická, Zuzana (referee)
Urban streams are influenced by number of human activities. Diploma thesis discusses the impact of urban drainage (specifically storm water drains) on toxic metal concentrations, of, in one of Prague's minor creeks - Zátišský Creek. Zátišský Creek flows from the right side to the Vltava River. The creek is 3080 m long with a natural flow 1.9 m3 /s. The creek is affected by seven storm water drains and three rain settling tanks. The creek was monitored from April 2009 to June 2010 during this period six sampling campaign was conducted. The samples were collected from seven remote sampling points, located both upstream and downstream from the storm water drains and rain settling tanks. The impact of storm water drains was assessed based on monitoring of toxic metals content in different parts of the aquatic environments, samples of water, sediment and aquatic biota (benthic organisms and attached algae) were collected and analyzed. The sediment samples and organisms were dried by lyophilisation (freeze dry), and digested in a microwave oven using a solution of nitric acid and hydrogen peroxide. Metal concentrations were determined by Atomic Absorption Spectrometry utilizing instrument Solaar S. Overall nine metals were identified: cadmium, lead, nickel, chromium, copper, zinc, aluminum, manganese...

The bachelor thesis describes semantic specifics of the Czech and Russian paremias which include "water" as a key word. The aim of the thesis is to discover similarities and differences among paremias which incorporate the "water" component formally. The main methods displayed in the following thesis are comparative and semantic analysis. In Part 1 the main group of paremias (proverbs and sayings) problematics is described, as well as their interaction with other types of fixed expressions (phrasemes, idioms, adages etc.). Part 2 contains two classifications one of which is based on semantic properties of the "water" component; the classification includes the most typical oppositions within which the component is realised in Czech and Russian. The second classification of paremias with key word "water" is founded on the theory of semantic fields (taxa).
