Study of titanium dioxide photocatalytic activity by fluorescence spectroscopy
Blašková, Martina ; Vala, Martin (oponent) ; Dzik, Petr (vedoucí práce)
This thesis deals with principles and methodology of evaluation of photocatalytic activity of titanium dioxide by fluorescence detection of hydroxyterephthalic acid and assessment of use this method in batch reactor. To the fluorescence study of activity we used hydroxyterephthalic acid as a primary product of oxidation terephthalic acid as a solution or in the form of immobilized layers. In the liquid phase we monitored fluorescence of hydroxyterephthalic acid by using a conventional fluorimeter and fiber spectrometer. In the solid state we monitored fluorescence of hydroxyterephthalic acid by spectrofluorometer with holder of solid samples.

Fluorescence probes for immobilized photocatalyst activity monitoring
Blašková, Martina ; Dvoranová, Dana (oponent) ; Dzik, Petr (vedoucí práce)
This diploma thesis deals with the use of fluorescent probes for evaluation of photocatalytic activity of immobilized photocatalyst. To the evaluation of photocatalytic activity of TiO2 were used three different fluorescent probes – terephthalic acid, coumarin and benzoic acid, wherein was monitored the increasing intensity of fluorescence of their oxidation products – hydroxyterephthalic acid, 7-hydroxycoumarin and salicylic acid for the photochemical degradation of various fluorescent probes. To the evaluation of photocatalytic activity was used solid phase (photocatalyst) – liquid phase (probe) system and was used three sources of radiation. Fluorescence of oxidation products was monitored by the fiber spectrometer and a conventional cuvette fluorometer.

Ekonomický přínos geocachingu pro konkrétní obce
Blašková, Martina ; Hrdlička, Pavel (vedoucí práce) ; Markéta, Markéta (oponent)
Diplomová práce Ekonomický přínos geocachingu pro konkrétní obec v teoretické části charakterizuje obec Třebenice. Využito je deskripce pro charakteristiku obce a její polohy, publikace zabývající se makroekonomií, je zde objasněna metodika určení ekonomického přínosu a nakonec je provedena deskripce geocachingu. Na základě vytvoření nových geocachingových schránek a dotazníku, který byl zveřejněn po dobu 8 měsíců je zjištěn ekonomický přínos pro obec Třebenice od lidí, kteří přijeli do obce primárně za geocachingem. Na vybraném vzorku 10 lidí za pomoci druhého dotazníku je zjištěn ekonomický přínos od lidí, kteří do obce nepřijeli primárně za geocachingem. Na základě těchto výsledků probíhá vyhodnocení a je zjištěn ekonomický přínos pro obec Třebenice a to prostřednictvím zvláštní formy cestovního ruchu a to geocachingem.
