Economic life of Hořovice town until 1945
Kroupová, Kristýna ; Hnilica, Jiří (advisor) ; Foltýn, Dušan (referee)
Podbrdsko is characteristic area of iron processing. The local production of iron goes along human lives for centuries. Komárov ironworks, which had a unique effect for the whole region, were very important in iron processing evolution. Domestic production was the second type of iron processing. Hořovice were well-known for domestic production of nails. Around 1850, domestic production began to gradually disappear. The reason was the move to the factory production. Many large iron processing factories was founded in Hořovice. Harmonicas manufacturing, match industry or hospitality services were other important economic sectors in Hořovice.

New sampling approaches for evaluation of real remediation studies
Kroupová, Kristýna ; Cajthaml, Tomáš (advisor) ; Innemanová, Petra (referee)
This diploma thesis has been carried out as a part of the project Utilization of long term (passive) sampling methods combined with in situ microcosms for assessment of (bio)degradation potential (PASSES). In the frame of the project groundwater remediation took place in the premises of Farmak a.s. in Olomouc using a pilot photooxidation unit and efficiency of the remediation was monitored through passive and active sampling methods. Pilot photooxidation unit is a technology based on the H2O2/UV-C photochemical oxidation of organic pollutants. In this work optimization tests of the pilot photooxidation unit were performed. The residence time of the groundwater in the photoreactors, required for its sufficient decontamination from pharmaceuticals and aromatic hydrocarbons, was 2.5 hours. 91% degradation of the pharmaceuticals and 80% degradation of aromatic hydrocarbons were reached during this interval. Although the removal efficiency of the pharmaceuticals by the photooxidation unit was high, the pilot photooxidation unit was not able to effectively remove the pharmaceuticals at the studied locality. By comparing the results of the pharmaceuticals from active and passive groundwater sampling during the remediation attempt, passive Polar Organic Chemical Integrative Sampler (POCIS) was found to be...

Influence of fish pond management, land use in catchment and climate change on species composition of blue-green algae blooms
Kroupová, Kristýna ; Stuchlík, Evžen (advisor) ; Pivokonský, Martin (referee)
The aim of the thesis was to explain expansion of cyanobacterial blooms and the change of their species composition in surface standing waters during the last 2-3 decades as a result of fishery management, land use in catchments, and climate change. Cyanobacteria possess a range of unique and highly-adaptable eco-physiological traits, which enable them a mass occurrence and a dominance over the other phytoplankton groups under recent anthropogenic changes (nutrient loading and rising temperatures). Moreover, many species of cyanobacteria produce cyanotoxins, which increase their resistence against zooplankton grazing and cause severe deterioration of the water quality. In consequence of changes in fishery management (a decrease in the use of superphosphate as a fertilizer during the year 1970), the fish stock density increased and the clear water phase disappeared. This is responsible for a change in species composition of cyanobacterial water blooms. Summer blooms of Aphanizomenon flos-aquae were replaced with A. flos-aquae var. klebahnii. The current composition of water blooms in ponds differs considerably from the typical composition in the 1990s. For example, recent expansion of Woronichiniana naegeliana is caused by the higher stock densities and the shift from a two-year cycle of fishery management...
