Introductory to laboratory courses from electricity and magnetism - preparation of learning material
DVOŘÁK, Lukáš
This bachelor work deals with preparation of the new education material for physical practicum from electricity and magnetism and improves its availability in appropriate form. The bachelor work consists of ten thematic tasks (measurements of thematic phenomena). Each task contains an introduction with brief theoretical description of a physic phenomenon with practical uses, list of employed instruments, aids to be done supplemented by electrical schemes and tables for obtained data. One chapter is also devoted to the general rules of physical measurements, data processing and estimation of calculation error. Last chapter deals with basic safety rules during measurement and the first aid for accident with electrical current.

Vliv intensity míchání na filtrační cykly při úpravě vody
Pivokonský, Martin ; Pivokonská, Lenka ; Švec, Martin
The aim of this contribution is to investigate aggregation efficiencies when high (G= 260 s-1) and low (G= 60 s-1) intensity agitation is applied for a treatment of surface water with high content of humic substances in a pilot size operation. It was established that high intensity agitation represented by a fluid layer of granular material (FLGM) can be more effective for an aggregation agitation than low intensity agitation with the help of the perforated baffles (PB). The FLGM improves performance of the filters because the filtration runs in the technological arrangement with FLGM took longer periods compared with low intensity agitation.

The Active Lifestyle of Undergraduates (Students of FEE CTU)
Valjent, Zdeněk ; Slepičková, Irena (advisor) ; Teplý, Zdeněk (referee) ; Krejčí, Milada (referee)
The active lifestyle of undergraduates (students of The Faculty of Electrical Engineering of CTU in Prague) The main aim of this study was to investigate what opinions, attitudes and practices of students of FEE CTU change and develop during the university studies in selected dimensions of an active lifestyle. It was done by the mixed research. The main research was carried out by using the method of repeated cross-sectional quest, when the incoming students to the first volume in 2007 in the count of 625 were immediately underwent the questionnaire quest after their entering to the school in October in 2007 and students of higher volumes in the count of 581 then at least after 4 passed semesters of their studies in May and June in 2008. Changes between the two groups were proved by "effect size", which was calculated in each indicator as the difference of relative frequencies of "median categories" of both files. To further identify the causes of found differences by questionnaire quest using statistical methods between the collection of students of the first volume and the collection of students of higher volumes, were used techniques of qualitative research at the conclusion - individual and group interviews with 32 students of higher classes and content analysis of written text, which was...

Search Engine Optimization
Havíř, Vojtěch ; Karlíček, Miroslav (advisor) ; Holeček, Jan (referee)
The subject of this bachelor thesis is search engine optimization for web pages. In the theoretical part of this thesis you can find a brief information summary about search engines on the Czech Internet. It is followed by a list of methods that can be used as part of an optimization for improving search engine ratings and also methods which can help only in the short term and are in case of detection penalized by the search engines. In the next part of the thesis is an overview of useful instruments that provide us with a variety of information about the level of web page optimization and other information that can be useful throughout the process of optimization. On the practical side, the thesis focuses on a level of search engine optimization of a student webpage unium.cz and some of the key changes that the owners have done are mentioned and their impact on a total number of visitors is evaluated. In the end you can find some recommended adjustments that could help to better ranking among the search engines.

Study of Properties of Titanium Dioxide Nanoparticles
Procházka, Jan ; Kavan, Ladislav (advisor) ; Mička, Zdeněk (referee) ; Šubrt, Jan (referee)
Charles University in Prague Faculty of Science Department of Inorganic Chemistry STUDY OF PROPERTIES OF TITANIUM DIOXIDE NANOPARTICLES. PhD Thesis Abstract Jan Procházka Prague 2009 8. This PhD thesis is based on publications and patent applications (1-9) to which the author contributed considerably. The list of the publications is attached at the end of this text. Systematic research of the properties of TiO2 nanoparticles brought new pieces of knowledge into syntheses of titanium dioxide nanoparticles organized in the templated structures. When the structures were used in the solar cells, their solar efficiency significantly surpassed the performance of the conventional TiO2 films. The study was focused on the engineering and optimization of parameters of the nanostructures used as anodes in the dye sensitized solar cells (DSC). Several new technical solutions have been delivered during the work on variety of TiO2 structures. First, the factors with an impact on the proper function of the TiO2 multilayer film were determined 9. and then, the layer by layer deposition technique was perfected. Introduction of phosphorus into the templated mesoporous film synthesis protocol represented significant progress. The presence of phosphorus stabilized the TiO2 surface area at a high temperature and allowed a...

Analysis of training indicators youths by cross country skiing and biatlon.
Jindřišková, Petra ; Gnad, Tomáš (advisor) ; Matošková, Petra (referee)
Title: Analysis ofyouth girls'training indicators in cross country skiing and biathlon. Aim of work: This thesis is focused on analyzing and comparing of training indicators of youth girls in cross country skiing and biathlon. It monitors a proportion oftraining means during year training cycle's seasons. Furthermore it is focused on training indicators and their importance in the performance. Method: For analysis of year training cycle we used a training indicator data of ten biathlonists and thirteen cross country skiers. All ofthose girls were youths (15-18 years) split into two groups of younger and older. The competition results were realized from Final Point Lists of seasons 2004/2005 and 2005/2006. Findings: They explain a usage of training means in year training cycle; compare data of training indicators in cross country skiing and biathlon and show influence of those data in the performance. Keywords: cross country skiing, biathlon, sport training, biological growmg up, and talents'selecting

Transdermal in vitro permeation of methoxytacrine. III.
Režňáková, Eva ; Doležal, Pavel (advisor) ; Bajgar, Jiří (referee)
Diploma Thesis 2006, Eva Režňáková Abstract The theoretical part gives a list of selected issues on transdermal drug delivery and summarizes information on Azone, including new technical information published in 2005. In vitro permeation experiments using the excised pig skin confirm the considerable potential for transdermal administration of 7-methoxytacrine. Using the isopropyl myristate as a vehicle the therapeutically valuable fluxes at about 15 [μg/cm2.h-1] were obtained. Transdermal acceleration and impact of 5% added amounts of methyl pyrrolidone and dodecyl pyrrolidone were not established. As a promising in this respect appears to use Azone and transkarbam 12.

Problem of the undernourishment and the food water resources
Polzová, Tereza ; Kuna, Zbyněk (advisor) ; Petr, Petr (referee)
The main focus of the final thesis are the problems related to the problem of undernourishment in affected
regions of the world, sea fishing and aquaculture.
In the beginning, the definition of the food problem in the world is introduced. The potential contribution of proteins from the sea production to human dietary is emphasized. Further, the exponential population growth is mentioned, influencing the future development and the food problem itself.
The second part of thesis is dedicated to fisheries and aquaculture. The importance and benefits of sea water resources as well as aquaculture is mentioned from the nutritional and livelihood point of view. Sea management and international regulations are playing
crucial role in the sustainability of the fisheries stocks. These are needed to eliminate the problems of fisheries and aquaculture and the degradation of sea ecosystems due to unsuitable fishing techniques.
At the end of the thesis a summary of all important information is listed. Followed
by possible solutions of these global problems.
