Porous composites based on siloxane resin for hard tissue replacements
Suchý, T.; Balík, Karel; Sochor, M.; Černý, Martin; Hulejová, H.; Pešáková, V.
2006 - English
A composite material based on polysiloxane and first on glass fabrics was prepared. The composite samples were prepared with controlled open porosity, the sizes of which were in the range: i) 0,2-0,4 mm, ii) 0,4-0,6 mm, and iii) >0,6 mm. For further improvement of osseointegration, a powder hydroxyapatite, particle size of 0,005 mm in the amount of 10 wgt %. The effects of surface treatment and hydroxyapatite matrix additives on osseointegration were studied by methods in vitro and in vivo.

Alternative utilization of organic wastes - their co-processing with coal
Kříž, Vlastimil; Bučko, Z.
2006 - English
Směsné vzorky hnědého uhlí s reálnými organickými odpady byly zplyňovány v laboratorní modelové zplyňovací jednotce pomocí vodní páry a oxidu uhličitého. Ověření možnosti společného zplynění hnědého uhlí a odpadní pryže. Samples of brown coal mixed with real organic wastes were gasified in a laboratory model gasification unit, using steam and carbon dioxide for gasification. The co-gasification possibility of brown coal/waste tires mixtures at industrial scale was verified.

Structure of the slopes in the middle catchment of the Losenice R
Hartvich, Filip
2005 - Czech
According to results of the state-of-the-art research, the present shape of the slopes is a result of collaboration of several influences, particulary the structural and tectonical pre-disposition, which interacts with the surfacial geomorphological processes. Stavba, tvar a vývoj svahů jsou ovlivněny několika faktory. Jedná se o predispozici údolní soustavy tektonickými diskontinuitami a foliací, které jsou poté dotvářeny vnějšími geomorfologickými činiteli.
