Aronia as a raw material for cosmetic production
Palkovská, Kateřina ; Sýkora, Michal (referee) ; Zemanová, Jana (advisor)
This bachelor thesis deals with extraction of polyphenols from fruits and leaves of aronia and consequent use of obtained extract in cosmetic production. In the theoretical part are information about the origin of the aronia, the botanical characteristics of Aronia Melanocarpa and about its utilization. Furthermore, the chemical composition of the plant material of the aronia is described, which is also common for fruits. At the end of the theoretical part are described extraction and separation techniques, methods of determination of total polyphenolic compounds and brief characteristics of the material safety data sheet. The experimental part describes the optimization of the prepared extract so that the extract contains as many polyphenolic compounds as possible. 50% ethanol at room temperature was shown to be optimal for leaf and fruit extraction, and the maceration time was found to have a significant effect on the polyphenolic compounds obtained. For the obtained optimized macerate, some chemical and physical properties such as pH, density, refractive index were determined for the purpose of producing a material safety data sheet and product specification. At the end of the experimental part were prepared cosmetic products with the addition of macerate from crushed aronia fruits.

Protection of Population against Consequences of the Chemical Accidents
Veverková, Ivana ; Hradil, Jaroslav (referee) ; Mika, Otakar Jiří (advisor)
This thesis aims to protect populations in chemical accidents. The introductory chapters present basic concepts related issues, basic terms on hazardous chemicals and their markings. You can also find here case studies of chemical accidents from the past compared to he present. It is important to note the consequences of accidents that can affect all sorts of situations. Regarding the issue of protection of the population, there is an overview of suitable means to prevent these dangerous substances, which continues to guide how to behave in case of an accident. This guide should be beneficial to anyone who is in the emergency planning zone and is therefore more vulnerable. At the end of this thesis we can find the state of readiness assessment and proposals to improve the situation.

Proposal of Special Database of Hazardous Chemical Substances for IRS
Vostrý, Jaroslav ; Mašek, Ivan (referee) ; Mika, Otakar Jiří (advisor)
Creating the proposition of the specific database of the hazardous chemical substances for the necessity the integrated rescue system of the Czech Republic. The basic properties of the hazardous chemical substances. The integrated rescue system and its components. The brief view of the selected databases from CR and abroad concerning the hazardous chemical substances. The proposed structure, content and range of the possible communal database of the hazardous chemical substances on the basis of the necessities and the requirements the particular components of the integrated rescue system and possibilities of the utilization.
