Determination of sensory active compounds in hops using GC-MS
Zlochová, Tereza ; Sobotníková, Jana (advisor) ; Čejka, Pavel (referee)
Determination of sensory active compounds in hops using GC-MS Abstract The goal of this thesis was to determine sensory active compounds from a sample of hops by gas chromatographic-mass spectrometric detection. Hop oils were selected for this determination which, despite its low representation in hops, contain up to several hundred components. Hop oils were exctracted using a new method based on fluidized-bed extraction. An integral part of this work was identifying the yield of the method that has become an instrument to defining the content of hop oils in different hop varieties. A comparsion of the obtained extracts with the literature was made and a search was done for the link between chemical structure of the hop oils and their representation in the hops sample with regard to its age. Keywords: exctraction, hops, hop oil, gas chromatography, mass spectrometry
Determination of non-volatile N-nitrosamines in malt
Vavrová, Dominika ; Sobotníková, Jana (advisor) ; Čejka, Pavel (referee)
The aim of diploma thesis has been development and optimization of method determination of N- nitrososarcosine and N-nitrosoproline in malt by gas chromatography with chemiluminiscence detector. Optimization of extraction method has been performed by response surface method. Quantification has been performed by internal standard method (N-nitrosopipecolic acid, in which matrix effects has been studied. These has been verified in münchen and pilsen malt, therefore matrix-matched calibration has been constructed. The developed method has been aplicated on wheat, münchen and pilsen malt. N- nitrosoproline was detected only in münchen malt and in other cases has been under limit of detection (LOD=4,0 µg/kg). N-nitrososarcosine was in all cases under limit of detection (LOD=3,7 µg/kg). The matrix-matched calibration has been constructed for experimental münchen malt with N-nitrosoproline concentration at 13,2 ± 2,9 µg/kg. Powered by TCPDF (
National-Cultural Comparison of Generations X and Y in the Czech Republic and Impact on Marketing Mix
Hebersteinová, Ilona ; Čejka, Pavel (advisor) ; Matoušek, David (referee)
The aim of this work is to provide a theoretical overview of research studies on cultural differences and their critical evaluation. The quantitative research on national and cultural comparison of generations X and Y in the Czech Republic will be implemented on the basis of a reduced questionnaire used in the research of European Values Survey in 2008. The data analysis will focus both on the current research and creating a time series of selected variables, using the results of previous research within European Values Survey. The starting point for comparing the behaviour of Generation X and Generation Y will be the national-cultural model of World Values Survey, and the results will be applied to marketing mix. The conclusion provides an overview and evaluation of the particular generations in terms of cultural performance as well as of marketing.

Study of diaphragm pump with linear motor
Čejka, Pavel ; Uttendorfský, Petr (referee) ; Pochylý, František (advisor)
The diploma thesis is aimed at the constructional design of diaphragm pumps with a linear motor. This pump is supposed to be used in medicine for pumping the blood or as an artificial heart. The basic facts, which are focused on the function of the heart and artificial heart, are mentioned in the first parts of the thesis. The next parts describe the diaphragm pumps and the constructional ways of their diaphragm fixation. Furthermore, the basic calculations, describing the function of the pump, are derived there. The basic parameters of the pump are also calculated. The thesis also contains the description of the body pump construction, whose working room is optimized by CFD calculation before the pump is manufactured. The final part of the thesis is concentrated on the measurement evaluation of produced pump model.

Rationality versus Irrationality in Managerial Decision Making
Daňková, Tereza ; Hiršová, Miloslava (advisor) ; Čejka, Pavel (referee)
The thesis focuses on rationality in decisions by managers. The terms rationality, irrationality and bounded rationality are defined in the first part. The current state of knowledge on the concept of bounded rationality in decision making is then followed by a specific consideration of managerial decision making. The chosen bounded rationality effects, including heuristics, are also described. The purpose of the second part of this study is to examine experimentally the differential uses of heuristics among the students of the Faculty of Management relative to completion of the Managerial Decision Making course. The effect of time to use of heuristics is examined as well.
