Thermoproperties of foundry moulds in dependence on different used foundry sands
Šuráň, Jiří ; Rusín, Karel (referee) ; Cupák, Petr (advisor)
The project elaborated in frame of engineering studies is submitting the study of thermal properties of holding mixtures using different types of sand. Were tested a total of 5 sands: zirkon, ŠH22, chromite, olivine and dunite. Molding compounds were tested for thermal capacity, thermal conductivity and heat accumulation. The highest heat capacity was achieved in dunite sand. The largest heat accumulation had mixture with chromite sand and the best thermal conductivity was found in a mixture with olivine sand.

Geochemické interakce horninového prostředí s plošnými kontaminanty - využití indikačních horizontů 137Cs ke studiu distribuce‚ vazeb a významu vybraných radionuklidů a kovových prvků v horninách oblasti Moravskoslezských Beskyd: Rešeršní zpráva o šlichtové projekci
Geomin, družstvo Jihlava ; Veleba, Bohumil ; Abraham, Miloš
Předmětem činnosti v roce 2005 byla aktualizovaná rešerše z hlediska šlichtové prospekce (příprava mapových podkladů geochemických anomálií) a odběry šlichtových vzorků ze svahovin a jejich příprava k analýzám.
