Guerilla marketing and its use in commercial communications
Koišová, Stanislava ; Filipová, Alena (advisor) ; Zeman, Jiří (referee)
The topic of my thesis is "Guerilla marketing and its use in commercial communications." The main objective of my thesis is to define new forms of marketing communication and to assess their possible application in the segment of small and medium-sized businesses, with particular emphasis on guerilla marketing. The thesis has three basic parts. The first two chapters present a theoretical view on marketing, commercial communications and new trends in the field, as well as on Guerilla marketing, through its definition, the definition of its main characteristics and basic types. The third chapter is formed by introducing two specific marketing campaigns using tools typical for Guerilla Marketing and was concluded with the analysis of the questionnaire.

Differences of autogeny and anautogeny population of mosquitoes Culex pipiens quinquefasciatus Say
DIVOKÁ, Petra
The aim of submited Thesis was to contribute to illustration on differences in development of female genital organs in autogeny and anautogeny population of mosquito Culex pipiens quinquefasciatus Say. Currently, a consequence of ekdyson agonists was tested for change evoked in the development and fertility this species. Gained results showed that in anautogeny population is process of vitellogenesis depended on blood- feeding. In autogeny population, there is no need to blood- fed during the first gonotrophic cycle. Tested compound indicated vitellogenesis in a sublethal doses then egg-laying was followed. In comparison with that, application of higher doses showed sterilisation effect. Gained results show this compound useful for regulation of mosquitoes population, especially in the area of disease transmitted by them.

Histological and histochemical methods used in study of development of internal male sex organs
VÁVROVÁ, Martina
Presented thesis devotes to comparative study of usability of fixation agents and colouring methods for the study of histology and histochemistry of Culex pipiens s.l. mosquito males. The study was carried out in males of Culex pipiens quinquefasciatus Say, which is a significant transmitter of filariasis. Histological and histochemistry studies of the structure of the whole abdomens or prepared testicles were carried out on the material fixed by fixation agents Carnoy and Bouin of Dubosque-Brasil modification. Fixed tissue was cast in paraplast or resin. Histological sections were done by means of automatic microtome Leica and half-thin sections by means of ultra microtone Reichert. Section preparations were coloured by Mayer or Harris haematoxylin or by colouring method according to Mallory. Semi-thin sections from materials cast in resin were coloured by toluidine blue. Fixation agent Bouin, Dubosque-Brasil modification proved as more convenient than Carnoy, either for the preparation of paraffin sections or for fabrication of half-thin sections from tissues cast in resin. The next advantage of this fixation is that fixed tissue can be stored for unlimited period of time without over fixation of the tissue as it is in the case of fixation by Carnoy. For general histological preparations Mallory colouring is apparently the most convenient from the used methods; it provides better orientation in coloured tissue thanks to the whole spectrum of colours-pink to red colouring of cell nuclei, blue colouring of tissue and secretions. In case of colouring of male genital organs all used colourings (Mallory, Harris and Mayer haematoxylin) seem to be comparable. Casting in resin with connection to colouring by toluidine blue (also histochemistry proof for carbohydrates) has shown to be suitable for visualisation of finer structures, in male genital organs particular developmental phases of male sex cells were distinguished.
