Adventist and Mormon congregations in Czechia: Distribution, position and manifestation of social capital
Reeves, Daniel ; Havlíček, Tomáš (advisor) ; Daněk, Petr (referee)
This research examines the congregations of two relatively young, "western" Christian churches (namely the Seventh-day Adventist Church and the Church of Jesus Christ of Latter-day Saints - Mormons) within Czechia, as sources of social capital for their members. To place these congregations into a spatial context and to shed light on the organizational base of their extensive social networks, the distribution and position (in terms of percentage of adherents as a portion of the total population) of the respective churches are explored at global, regional (European) and local (Czechia) levels. Quantitative and qualitative methods are used to attempt to measure the strength of Adventist and Mormon congregations in Czechia as a viable source of social capital and to explore the diverse ways in which members benefit from belonging. The levels of trust and participation measured within congregations indeed suggest that they present ideal conditions for the development of social capital. Experiences and specific examples of active participants in Adventist and Mormon communities in Czechia confirm the existence of social capital benefits arising from their participation in a congregation.

The process of ERP system selection of a distributor
Gregůrek, Tadeáš ; Lorenc, Miroslav (advisor) ; Martínez, Felipe (referee)
This thesis deals with the choice of ERP system from the perspective of companies engaged in the distribution of lighting signs. The theoretical part covers the concepts of ERP systems, current trends in ERP systems, different versions of these systems and the risks that may arise in this process. The practical part is focused on describing the distribution company, current ERP system that the company uses and the parameters that existing and new system have to comply. The primary aim of this thesis is to evaluate current ERP system offer on the market and to recommend the best suitable system for Dencop Lighting through decision matrix. For this part, methodology of analysis is used. The secondary aim is to asses risks that may arise in the process of changing ERP system.

Investigation of titania dispergation by ball milling
Gregůrek, Martin ; Pekárková, Jana (referee) ; Dzik, Petr (advisor)
This bachelor’s thesis deals with preparation of dispersed suspensions of titania suitable for material printing. The theoretical part deals with the properties of dispersions, methods of their preparation and capabilities analysis particle size of the dispersions. Experimental work has been focused on the study of the efficiency of milling depending on time. The particles were prepared by ball milling with glass balls in n-butanol of oscilating shaker LT2. Characteristics of the dispersions was evaluated on the device for measuring particle distribution Lasentec D600L by laser diffraction. The results were verified on the devices Zetasizer Nano ZS using dynamic light scattering and scanning electron microscope Carl Zeiss Ultra Plus.

Oral morphogenesis in the Mexican axolotl: developmental origin of tooth germs in evolutionary contexts
Soukup, Vladimír ; Černý, Robert (advisor) ; Slípka, Jaroslav (referee)
Mouth in the majority of vertebrates develops throughout an ectodermal stomodeum which posteriorly contacts the foregut endoderm, together forming an oropharyngeal membrane. This ecto-/ endodermal membrane gradually thins and become eventually perforated, which causes opening of the stomodeal cavity into the pharynx. Teeth are then understood as organs arising within the stomodeal part of the mouth, where the ectodermal epithelium produces tooth enamel and neural crest mesenchymal cells form dentine and tooth pulp. This project was meant to study the dynamics of the ectoderm and endoderm during the formation of mouth and teeth in the Mexican axolotl. By utilizing transplantations of the oral ectoderm from GFP-transgenic embryos and injections of fluorescent tracer DiI into the endoderm, it was possible to follow the fate of both germ-layers during the course of embryonic development into details. By using this approach it was demonstrated that the mouth in the axolotl develops in a different way, i.e. via the stomodeal collar. Teeth were found to arise within the stomodeal collar ectoderm as well as in the more posteriorly situated endodermal areas. Moreover, some tooth germs were generated also directly at the ecto-/ endodermal boundary. Thus, the formation of teeth does not seem to primarily...

Potential photodynamic active compounds based on nitrogenous macrocycles
Kostka, Miroslav ; Hartl, Jiří (advisor) ; Macháček, Miloš (referee) ; Král, Vladimír (referee)
77.. SSUUMMMMAARRYY During the dissertation I have managed to prepare various compounds of phthalocyanine (Pc) structures and measure their production of singlet oxygen. The synthesis of Pc is not overly problematic, however complications arise during purification. Phthalocyanines are known for their instability in visible light spectrum and their aggregation in more concentrated solutions. The singlet oxygen quantum yield is usually low at the aggregates, thus further work is limited. The aim of my work was to create new Pcs with both increased solubility and functional groups suitable for conjugation with biomolecules. First experiments were performed with silicon complex of Pc (SiPc). However, synthesis of axialy substituted SiPc was not successful. Similar compounds with peripheral alkylsulphanyl substitution were also not obtained. These compounds disintegrated during synthesis. Another method that I have tried to insert a central aluminium atom into a Pc platform that was soluble into common organic solvents. Not all peripheral substituents were suitable (5, 6). Even by this method I haven't achieved satisfactory reactions yields. We have then turned our attention to zinc and magnesium complexes of Pc (ZnPc, MgPc). These synthesis methods are already known. Their reaction conditions are less...

Indoor optical wireless link design
Kaňa, Leoš ; Tošovský, Petr (referee) ; Hudcová, Lucie (advisor)
In last years phenomena of wireless communication technologies became a primary interest of big development laboratories whole world. Domain of point to point links which are realized by laser technology with narrow beam divergence and very sensitive photo-detectors is ordinarily used these days. This trend of using light waves as carrier medium turned interests of scientist to the sphere of wide area networks which is domain of wi-fi radio technologies. One of new trends in this sphere is also in-door free space optics. With expansion which leads to using LED's in everyday applications and with technological progress of last years, also grows tendency of most effective utilization of LED systems. The result of this effort is thought which considerate LED as source of artificial lighting and source of carrier medium for modulated signal. This kind of device must fulfill hygienic standards for illumination and also must be able to work with high frequency by which is signal modulated. These systems can provide links with sufficient capacity in order of hundred megabits.

Measurement of camera spectral response
Melich, Radek ; Václavík, Jan ; Žídek, Karel
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.

This master‘s thesis treat of car safety. It includes an introduction into already existing active and passive safety systems and briefly describes their basic principles. It also includes a description of basic principles of car electronic systems. It will acquaint us also with elementary calculations in the area of car crashing into a solid obstacle. On base of this information was developed and consequently realized development module of an automatic car accident alarm that transfers information using SMS messages to a cell phone. The message contains date, time and GPS coordinates of the accident and acceleration sensor readings in three axes.
