Efektivita nástrojů podpory prodeje v sektoru FMCG
Müllerová, Lucie ; Karlíček, Miroslav (advisor) ; Stříteský, Václav (referee)
The overall goal of this thesis is to draw relevant conclusions about the nature, impact and characteristics of sales promotions within the category of ready-to-eat cereals, based on thorough analysis of their effects. It is studied, whether sales promotions are beneficial or not for the long-term sales and how the shopper behaviour is influenced by the sales promotion activities. The effects of sales promotion on the overall consumption in the category are analyzed and other factors influencing the consumption are observed.

Optimization of measurements by the HPGe detector with a very low background for achievement of the low MDA values
ČERNÁ, Kristýna
Abstract My thesis examines the measurement optimalization when the semiconductor HPGe detectors with a low background and a high relative efficiency are used for achieving low values of MDA (minimum detectable activity). I conducted my research in the Department of Spectrometry of SÚRO (National Radiation Protection Institute) in Prague. In this laboratory the standard geometries of detectors with lower efficiency are used. The aim of this thesis is to offer a proposal of new geometry, sizes and shapes of measurement cells which will better correspond with the demand for higher efficiency of updated detectors. The assignment was to find the best mathematical function to descibe the correlation between efficiency and the direction of the radiation point source towards the detector. This function is derived from experimentally obtained data. To conduct measurements, three kinds of detectors with high relative efficiency used for activity measurements at different geometries were selected. As the source of gamma radiation, the point sources with energies of 46 keV, 661 keV, 1332 keV in different distances and positions were used. The function was applied separatelly to each of the three detectors and to the areas above the detector and sidewards of the detector. The objective of the research was to project new measurement geometries or to optimalize the current ones which could be used also in other detectors with high efficiency. After integrating the function in the cylindrical area above the detector and the annular area sidewards of the detector, areas contributing substantially to the overall efficiency were determined. These areas may be considered to be the optimal sizes for new geometries in given positions. After combining all the optimal areas above the detector, sidewards of the detector and for selected energies and the detector, optimal sizes of a new geometry were found. The function can be used both in the front part and the side part of the detector but its validity is limited. The value of MDA for the particular geometry is in indirect proportion to the efficiency square root and thus this new geometry should lead to minimum values of MDA.

The assessment of an impact of the quality management system on his effectivity in state administration
DUCHKOVÁ, Eva
The companies and organizations should take care about the control of quality. That´s why they boot quality into their systems of management. An implementation of such approaches presents the chance to directly benefit from the experiences gathered in the implementation in private sector. Main goal of this diploma work is the analysis of the systems of quality management in public administration. It treats with the assessment of an impact of quality management system on his effectivity in state administration. First chapter extends the knowledge of the systems of quality. This part talks about specific demands for quality management system used in public sector. The knowledge from first part was used in next chapter for analysis of the situation in selected organization. To review the impact of system, The municipal authority in Vsetin as a representative of transferred state administration, and Czech statistical office as a representative of central state administration were choosed. System of quality management applicated in these two examples was analysed.

Standard bioassay of the efficacy of entomoparazitic nematodes
TRNKOVÁ, Zuzana
The efficacy of three entomopathogenic nematodes (EPN) of family Steinernematidae was tested in different laboratory conditions in this study. The virulence of Steinernema arenarium, S. carpocapsae and S. feltiae was evaluated to fourth-instar larvae of Galleria mellonella and Tenebrio molitor. Standard temperature (25°C) and humidity (12,5 %) was used in bioassay No I. Trial No II focused on impact of temperature 10, 15 and 25°C on effectivity of S. feltiae and S. carpocapsae. Bioassay No III examined the influence of lower humidity and in consequence rehydration on virulence nematodes.
