Urbánková, Lenka
Bachelor thesis describes the issue of biodegradable waste and the way it is treated. There is also described the possibility of secondary use and converting biodegradable waste into compost or some form of energy. The section focused on the composting process is more fully described, because it is the most widely used method of aerobic treatment of biodegradable waste. For an explanation The Central Composting Brno was chosen as an example of the practice. Composting works since 2007, its current capacity is 70 000.103 kg of bio waste and is located in the Brno - Modřice. It uses the technology with forced aeration and helps to return organic matter to the cycle of matter in nature. The output products are composted organic fertilizers Black Dragon, Green Dragon, and substrate Gray Dragon.

Urbánková, Lenka
This thesis studies an influence of hemp added to feed rations on the organism of tested animals. In this feeding experiment the effect of supplied hemp to weight increments and antioxidant activity was observed. The tested animals were rats of strain Wistar albino. The experiment was performed with 20 male rats which were divided into 4 groups. Two groups were fed with hemp mixture and other two with control mixture. During the experiment subjects were weighed once a week and weight gain and feed consumptions were recorded. Spectrofotometric method Folin-Ciocalteu for determinations of polyphenolic compounds was used. Antioxidant activity was measured for the individual samples of feed and liver tissues of tested animals. They were FRAP and TEAC method used. The results of measurement of antioxidant activity in liver tissue proved inconclusive for both methods. Demonstrable differences were found only in samples of feed. The processing was used ANOVA statistical method using the Scheffe test.
