Development and assessment of selected properties of emulsion cosmetics
Kuchyňová, Jitka ; Souralová Popelková, Miriam (referee) ; Zemanová, Jana (advisor)
This bachelor´s thesis focuses on assessment of selected properties of emulsion cosmetic product called Soothing face mask, which is produced by SynCare company. Thesis is targeted on rheological properties of the product. Basic rheological properties were measured by Brookfield viscosimeter in experimental part of the thesis. Short part of the text is dedicated to thermic analysis field, which may provide some useful pieces of information for storage of products in cryogenic temperature and development of emulsion products with good cryogenic-temperature resistance. Chemical properties of Soothing face mask product are expressed by description of particular characteristics of cosmetic ingredients in the product.

Stability of humic acids in production of eye drops
Lišková, Kateřina ; Mravec, Filip (referee) ; Bilerová, Helena (advisor)
Glykoaminoglykans are the biological active compounds, which significantly affect the physiological processes in living organisms from under low concentrations. Marked representative of this group is hyaluronic acid. It is linear polysacharid, whose primary structure is consists of D-glucuronic acid and N-acetyl-D-glucosamin linking by glycosidic bonds (13) and (14). It is occurring connective tissues, synovial fluids and vitreous humor too, in which forms system with unique rheological and optical properties. Except of human body is its concentration especially high in the cockscombs. Hyaluronic acid has very high ability to bonding molecules of water, increasing molecular weight a then viscosity of aqueous solutions too. This fact together with characteristic viscoelasticity and lubricating properties plays an important role in preserve of organism. Acid, but its salt too form basic component of compounds using in ophthalmic surgery. It is using in extraction of cataract, operation of glaucoma, implantation of crystalline lens and corneal grafting too. Aim of this bachelor work was a determination of stability of hyaluronic acid solutions along the production of eye drops. Main objective was using by rheological measurement detect the influence of addition polymers (PVP, PACA, PEOX, PEG, PUD, PEI) and different pH on stability, degradation aqueous solution of hyaluronic acid at sterilization in the steam autoclave respectively.

Common topics of Science and Theology in high school education
ČANDOVÁ, Jana
In the introduction this thesis classifies different conceptions of the relationship between science and faith. Then, it focuses on common topics of natural science and theology in secondary education. It summarises and reflects the experience of teaching practice and deals with the practical options for Christian issues which the students are usually interested in. The topics are presented in relation to a specific high school curricula and sorted into three parts: Death and dysthanasia, Time and rheology, Deus vere ludens et homo ludens. Some practical examples and recommendation for teaching practice are also mentioned.
