Stability of natural oils used in cosmetics and pharmaceuticals
Milerová, Helena ; Enev, Vojtěch (referee) ; Hurčíková, Andrea (advisor)
The bachelor's thesis deals with the issue of stability of selected plant oils used in the cosmetic industry. Six oils were subjected to analysis using differential scanning calorimetry (DSC), which determined the oxidation onset temperatures for all samples. The aim of the thesis is to evaluate the use of the DSC method for obtaining data on the thermo-oxidative stability of plant oils. For comparison, the samples were also measured using the Rancimat method, a commercially established procedure in which the samples were exposed to elevated temperature using air flow. The results yielded induction periods, which indicate the time until the sample starts to oxidize. After measuring the samples using both methods, the oils were ranked according to their oxidative stability from the most stable to the least stable. The resulting sequences from both methods were nearly identical. DSC has proven to be a suitable method for measuring the thermo-oxidative stability of plant oils.

Role of art education teacher focusing the presentation of school creative production
Milerová, Helena ; Kitzbergerová, Leonora (advisor) ; Fulková, Marie (referee)
Researched topic of the thesis is The role of art teacher education focused on the presentation of art works. Art teacher is given in context to the curator of the exhibition, the curatorial activities. Curator of the exhibition is a relatively new professional level, very important especially for contemporary art. The theoretical part of the work confronts profession of educator and curator of the exhibition. It searchs for a new fields of two environment meanings that combines art. Interest is whether and how the profession of the teacher and curator of visual encounter is met. I search and describe this during studies. Subsequent interest is the presentation of pupils' work, and whether it is an important part of the activity of fine art teacher, looking for steps it goes through. As well as what the teacher's attitude towards exhibitions and other forms of presentation of pupils' work. Educated high school students are familiar with the possibilities and circumstances presenting their own works of art, learn about the background of the exhibition project. On the basis of the theory and history of art, conceptual art are the art works created and then are applied for the exhibition. From the didactic point of view exhibition is an educational component of learning. Of the findings, supported by...
