Phytoplankton of the Tatra lakes: factors influencing taxonomic composition and biomass
Červenková, Lenka ; Nedbalová, Linda (advisor) ; Štefková, Elena (referee)
The aim of this diploma thesis was to describe species composition and biomass of phytoplankton in the Tatra Mountains lakes (Slovakia, Poland) and environmental factors influencing them. The surface layer of 89 lakes was sampled in September 2004. Flagellates from Chrysophyta, Dinophyta and Cryptophyta most frequently dominated the phytoplankton biomass. Lake in the same valley usually differed in their dominant taxonomic group as a result of different lake morphometry, catchment type and detailed geological structure. Based on the level of phytoplankton biovolume, the majority of lakes were ultraoligotrophic and oligotrophic, however, mesotrophic and even eutrophic conditions were recorded in some forest and meadow lakes. An allometric relationship between phytoplankton biomass and chlorophyll a was revealed. Specific chlorophyll content did not differ among taxonomic groups. Altogether 233 species were determined, the most diverse group were Chlorophyta. Species richness of lake was 3-46 and it was negatively correlated with altitude and positively correlated with lake area. The majority of species were rare both in term of biomass and number of lakes occupied by a particular species. Average local species biomass was positively correlated with regional distribution. The similarity of species...

Financial Evaluation of Investment Project
Červenková, Lenka ; Sieber, Martina (advisor) ; Vlček, Josef (referee)
(in English): The main goal of this bachelor work is the evaluation of the efficiency of the investment to the family passive house. The task was to identify, whether the investment to more expensive passive house is worth the expected annual savings resulting from the energy savings on heating in the passive house. The efficiency of this investment was examined on the specific case of a selected passive family house near Prague and the evaluation of this investment was done by assistance of dynamic economic methods and indicators. The first chapter of the theoretical part deals with the fundamental questions about passive houses. The second chapter is focused on investment activities and the methods and indicators of financial evaluation of investments. The practical part deals with the financial evaluation of the specific passive house itself. The indicators used for the evaluation showed, that the investment is not effective and profitable. In the end, the situation was examined, when the investment would be supported by the state financial grant. In this situation the investment to the passive house would be profitable.

Spondylopathy in La Tene period population of Bohemia and Moravia
Červenková, Lenka ; Likovský, Jakub (advisor) ; Velemínská, Jana (referee)
La Tène period is the period of Celtic civilization. This period is now one of the most popular epochs, not only in Bohemia, but generally throughout Europe. It is a period of history between the year 400 BC and the turn of the era - part of the Iron age. Skeletal remains of people from historical periods tell many things about their health and lifestyle. Diseases of the vertebrae and spine are most common pathological findings amongst skeletal material. This work is devoted to findings of congenital defects and degenerative diseases of the spine in the skeletal files from La Tène period of Bohemia and Moravia. Powered by TCPDF (www.tcpdf.org)

Analysis of competition in the regional toy market
Červenková, Lenka ; Vávra, Oldřich (advisor) ; Pešek, Ondřej (referee)
My thesis deals with analysis of competition in the local toy-market concretely with analysis of two comparable toyshops situated in shopping-centers in central Prague. Preliminary I present and define key terms that are essential at comparison of competition ability (competition, competitive advantage, toy market, customer and his specifics). To make my own research I elected standards that significantly influence customer satisfaction while shopping and determine possible future shopping, and created questionnaire. During valuation I commented point gains, looked for strengths and weeknesses and designed possible improvements. Total score were used to compare competitive ability of both the firms. My thesis is not only instruction manual for surveyed shops and determination of their competitive ability. It could be used as a general guide to increase competitive ability of other firms or as a starting point for further consecutive thesis and researches.
