Proposal of Database for Pivní burza pub
Heneš, Radek ; Hrušková, Lenka (referee) ; Kříž, Jiří (advisor)
Restaurant and pub Pivní burza is first of its kind on Czech market. The Pub operates on the principle of exchange (organized market), where the price of beer is floating and with increasing demand for one product, price of the other products is changing in real time. Customer can monitor the price developments and realize an order on the touch panel, which is located on the restaurant tables. Thesis is focused on the analysis of the current status of the restaurant, own solution design and suggestions for future improvements.

Radon-in-waters measurement methods
Hrušková, Lenka ; Goliáš, Viktor (advisor) ; Třískala, Zdeněk (referee)
Higher concentrations of radon are probably harmful to our health, on the other side its lower concentrations have terapeutical effect, which is used in a spa. Its characteristical properties are suitable for mineralogical research, hydrological and environmental studies and for an earthquake and vulcanic prognosis. In this work, there are explained methods of ray measuring, scintilation detektor and ionization chamber and there are compared devices like radon-in-air monitor, device with a hydrphobical membrane and device with a method using olive-oil. dtto cz.

Dlouhodobé skladování sadebního materiálu buku lesního (Fagus sylvatica L.)
Hrušková, Lenka
This bachelor thesis aims to determine suitable conditions for long-term storage of European beech planting stock in freezing conditions. In this thesis, we used a method of storing in freezing boxes with temperatures set at -3 °C, -6 °C and -8 °C. The main objectives of the thesis were to determine the temperature limit for the plants survival, the length of storage and acclimatization of the plants before planting, the effects of the fungicide application and the insulating properties of cardboard boxes and polyethylene bags. Two evaluations were performed in which we evaluated morphological parameters, plant vitality and plant loss. Our results suggest the temperature -3 °C as optimal for long-term storage in freezing boxes. The plant survival limit was set at -6 °C. No significant differences were observed between the types of packaging and the application of the fungicide for long-term storage in freezer boxes was not found to be necessary. For suitable acclimatization, we recommend more than 4 days. The total period for storage can reach over 4 months.

Springs of the radioactive medicinal water in the Lázně Libverda - Świeradów-Zdrój area
Hrušková, Lenka ; Goliáš, Viktor (advisor) ; Vylita, Tomáš (referee)
The main radionuclide causing high water radiation is 222 Rn with half-life 3.82 days. Concentrations of radon in radioactive mineral water in the Krkonoše-Jizera Crystalline Complex are very high and do not correspond with the concentration of uranium in the source rocks. These springs probably well up near the uranium mineralisation. Search for radioactive mineral water started in 2005 in Orlice- Sněžník Dome built by orthogneisses, which was the first promising area for such research. The research continued to the areas of Jánské Lázně and Horní Malá Úpa built by the Krkonoše orthogneisses in the next few years. In the last two years research was conducted in Lázně Libverda. Until then there were only a few known springs with radioactive mineral water. Lázně Libverda-Świeradów-Zdrój area is located in the Krkonoše-Jizera Crystalline Complex built by Cambrian/Ordovician orthogneisses and Variscan granite pluton. Jizera orthogneisses and the contact of these two objects were considered to be very promising in terms of finding springs of the radioactive medicinal water. Another criterion for a successful exploration is also an abnormal tectonic deformation of the zone. Uranium exploration was also conducted in 1950s, so we could use data available from the emanatory survey on a scale of 1:5000 and...

Phytoplankton in experimental ponds: colonization and seasonal succession
Hrušková, Lenka ; Nedbalová, Linda (advisor) ; Lukavský, Jaromír (referee)
Artificial ponds are excellent for the study of phytoplankton ecology. They permit repeatable initial conditions and sufficient replication of independent experimental units in complex experiments to test hypotheses about the control of structure and function in natural communities. There were 20 experimental ponds constructed in Kokoř nsko Protected Landscape Area, from which samples were taken and analyzed. This study was part of the EU BIOPOOL. During the first two years after the filling of the ponds the colonization and the seasonal development of phytoplankton communities in the ponds were examined. The phytoplankton species composition was determined, then species richness and relative abundance of individual taxa were quantified. Species composition data were compared with the environmental parameters measured (temperature, oxygen concentration, pH, transparency, conductivity, depth, chlorophyll-a concentration, and zooplankton). In the spring 2007, the ponds were periodic, and followed a similar trend over time (February- April). There were dominated by the following taxonomic groups: Dinophyta, Chrysophyta, Cryptophyta, and Euglenophyta. After installing foil on the bottom of the ponds, the ponds were of permanent character. In terms of environmental parameters, the individual ponds...
