Ecotoxicological Evaluation of Industrial Waste Materials and Anorganic Composites Containing Waste Materials
Pavlitová Letková, Zuzana ; Zlámalová Gargošová, Helena (referee) ; Pulkrabová,, Jana (referee) ; Beklová, Miroslava (referee) ; Vávrová, Milada (advisor)
This work sums up results of tests of ecotoxicity that were made on different kind of industrial waste materials like classical ash, fluid and fly ash, slags as well as anorganic composites containing waste materials. Composites might be used for building materials in the future. Ecotoxicological tests were used for evaluation of ecotoxicity, represented by 4 trophic levels, with several bioindicators evaluated at different exposure time periods. The battery of classical tests includes a growth inhibition test of the freshwater alga Raphidocellis subcapitata, an immobilization test of the cladoceran Daphnia magna and freshwater fish Poecilia reticulata and a test of inhibitive effects on the root growth of white mustards Sinapis alba. Tests with enchytraeidae, collembolan and lettuce were chosen from group of contact tests. It was realized confrontation between classical test with seeds of mustard and contact tests with seeds of lettuce. Results of ecotoxicity tests were determination of percentage of mortality, immobilization, stimulation or inhibition of growth for testing organisms. It was made comparison of results individual ecotixicity tests. Results of classical aquatic tests were compared with contact tests realized in artificial ground.

Development of multilayer polymer floor systems
Tesař, Filip ; Vyhnánek, Miroslav (referee) ; Petránek, Vít (advisor)
Multilayer polymer flooring systems belongs to widespread materials for industrial constructions and also for public constructions. These are mostly two-components polymeric materials based on epoxy. The main aim of my thesis is to make list of requirements for multilayer polymer flooring system and utilization of waste materials as fillers in polymer epoxy. Then use this knowledge for development of multilayer polymer flooring system and propose the new recipe and primary test´s for this material.

Creative transformation of waste materials in kindergarten
REITHAROVÁ, Eva
In my diploma thesis I deal with the usageof the waste materials in the nursery schoul based on the expenence and the manipulation. The thesis consists of thrce parts. In theoretical part I deal with the type sof the waste materials, the description of materials and the ecological adecation in preschool age. The practical part is based on the metodology which id tounded on the experimental game and the manipulation with the waste materials. The metodology is based on the everyday subjekt in the nursery schoul.
