Possibilities of alcali activation of steel slag
Frýbortová, Iva ; Rovnaník, Pavel (referee) ; Opravil, Tomáš (advisor)
The properties of alkali activated steel slag as a clinker-free binder system was studied in this thesis. The aim was to find the optimal composition of alkaline activator providing good properties of the prepared binder. Sodium and potassium hydroxides and alkaline silicates in the form of solutions and powders were used as the activators. Mixture of steel slag, fluidized bed coal combustion ash and water without any activating ingredient was another binder system studied in this work. Mechanical properties, such as compressive and flexural strength, of the mixtures were determined. Calorimetric measurements were used for the study of hydration process, scanning electron microscopy for the examination of microstructure.

Media Image of the Fu-Fu Cult
Růžičková, Martina ; Santos, Luis Artemio De Los (referee) ; Stratil, Václav (advisor)
In an interconnected world of alone standing individuals, artistic individuality is in many cases expressed through attempt to question culture of branded corporations and thus replace it with artist’s independent mind that is able to create works as commentaries and alone standing, “independent” products. To create post-ironic individuals, individuals as “highly diversified” brands. So long they’ve dreamed about wide spread and legitimization of their work, their art. This was partly done by overwhelming their followers’ social media feeds.

The concept of waste and the classification of waste
Trojanová, Tereza ; Sobotka, Michal (advisor) ; Humlíčková, Petra (referee)
The thesis deals with the legal definition of waste; it analyzes the meaning of the concept of waste in international, European and Czech legislation. The paper mentions the rich jurisprudence of the Court of Justice of the European Union, which has significantly influenced the concept of waste in the Directive 2008/98/EC. The thesis also concerns with the Act. No. 185/2001 Coll., on waste, and with the concept of by-product and concept of end-of-waste status. The paper also shows the classification of waste in the Czech legislation and defines the categories of hazardous waste, non-hazardous waste and municipal waste.
