Pekařová, Kateřina ; Čábelka, Miroslav (advisor) ; Laštovička, Josef (referee)
Analysis of standards and tools for displaying 3D models on the web Abstract The main goal of this diploma thesis is to analyze selected current standards and tools for displaying 3D objects on the web. In the first part, selected technologies are described in detail. The practical part is divided into two phases of testing, in which the testing conditions are determined, followed by the design of the variables to be tested, and the implementation in the actual test web pages. The tools prepared in this way are then tested using developer tools in the web browsers themselves. The results of this testing are graphically processed and evaluated. Keywords: 3D, web, analysis, WebGL, Three.js

Cationic surface active compounds and evaluation of its properties
Pekařová, Kateřina ; Nováková, Veronika (advisor) ; Kuchařová, Monika (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Biophysics and Physical Chemistry Consultant: PharmDr. Jan Marek, Ph.D. Supervisor: doc. PharmDr. Veronika Nováková, Ph.D. Student: Kateřina Pekařová Title of Thesis: Cationic surface active compounds and evaluation of its properties Quaternary ammonium salts are used as surfactants in many branches of the food, pharmaceutical and chemical industries. The basic properties of these substances were studied in the thesis. The critical micellar concentration of the homologous series of five substances was determined using the conductometric method. The theory of declining critical micellar concentration with the increasing length of the side alkyl chain has been verified. The hydrolytic activity of two commonly used cationic surfactants benzalconium chloride and benzoxonium chloride for the decomposition of the organophosphorus pesticide fenitrothion was tested. For these two substances, the effect of pH and temperature changes was evaluated. The influence of tenside concentration was also monitored. Benzoxonium chloride at 50 řC and pH 11was found as the most effective hydrolytic catalyst for the decomposition of the organophosphorus pesticide fenitrothione.

Proposal of methodology for Protected Landscape Area maps production
Pekařová, Kateřina ; Lysák, Jakub (advisor) ; Jaroš, Jakub (referee)
Proposal of methodology for protected landscape area maps production Abstract The main goal of this bachelor's thesis is to create a proposal for a methodology for creating maps of protected areas in Czech Republic. The first part of the paper is devoted to acquaintance with the basic knowledge of thematic cartography with emphasis on the basic cartographic rules in the creation of maps. The following is an evaluation of existing maps of protected areas in the Czech Republic and in the world. An overview of data sources is also given. Based on the findings from the first part, the practical part of the thesis then creates the proposal of methodology itself, which is tested on sample maps. Keywords: thematic map, nature conservation, spatial data, cartographic generalization, methodology
