NEW ON THE „OLD“ – Brno, Bratislavská - Stará Corner
Urminská, Barbora ; Mikulášek, David (referee) ; Františák, Luboš (advisor)
It was one of main points of the project to design a viable building which would fit in the locality on the corner of Bratislavská and Stará street. Project of a polyfunctional but mainly residential object is a logical result. Shape of the building flows from two ideas: to close blank space on the corner but also to keep a part of place open, to be used as a public space which the locality lacks. That is why the height and front facade position links to both neighbouring objects. Yet on the corner, in front of the theatre, the building rises to height of two storeys so the corner stays free and usable as a public space.

Waste water toxicity.
Urminská, Barbora ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
The theoretical thesis is focused on evaluation of toxicity of wastewaters and effluents and also on specification of legislative requirements related to the subject. As the negative effects of effluents on receiving water do not always depend on presence and concentrations of toxic chemicals contained in the effluent, analyses of physical and chemical parameters only is not sufficient and does not provide adequate results. The aim of the thesis is to show the importance of using ecotoxicological biotests as a necessary part of whole effluent toxicity assessment and to describe approaches to this testing in the European Union countries.

Assessment of the efficiency of wastewater treatment plant using ecotoxicity tests
Urminská, Barbora ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
The possibilities of environmental pollution control are increasing and more advanced wastewater treatment methods are being emphasized, as well as more specific control of contaminants presence in treated waters. That is why it becomes relevant to perform not only chemical analysis but also ecotoxicological bioassays as the means of evaluation of biological effects caused by wastewater discharges to ecosystems. No wastewater treatment plant is able to treat the water perfectly – it can only decrease the pollution level to an acceptable value. Therefore it is important to find out if the treatment process is sufficient to provide a satisfactory decrease of ecotoxicity and also what effects to the organisms in recipient will be caused by wastewater discharges. The thesis is focused on the evaluation of wastewater ecotoxicity. In the experimental part of the thesis, wastewater samples were collected at four wastewater treatment plants in the Czech Republic. At one of them also the sludge samples were taken. The aim was to evaluate the efficiency of wastewater treatment by selected ecotoxicological bioassays. The results have shown that the efficiency of wastewater treatment plants with secondary treatment is sufficient to reduce acute toxic effects to the minimum. Average toxicity removal was over 80 % at three of four evaluated wastewater treatment plants. At the fourth WWTP it was 41 %, however, at this WWTP high efficiency of treatment is not necessary.
