Use of exothermic sleeves for aluminium alloy castings
Jakubec, Petr ; Martinák, Rostislav (referee) ; Kaňa, Václav (advisor)
This master's thesis deals with the influence of the exothermic riser sleeves on the solidification time of aluminum alloys. The thesis is divided into five parts. The first chapter describes solidification of cast alloys. The second chapter deals with the designing of risers. The third chapter is focused on the types of risers. The fourth chapter describes ways of intensification of risers and chemical composition of exothermic and insulating mixtures for production of riser sleeves. The main fifth chapter focuses on experimental measurements of temperatures and solidification time of aluminum alloy in castings, risers and exothermic and insulating riser sleeves.

Metodika uchovávání předmětů kulturní povahy
Selucká, Alena ; Mrázek, Martin ; Štěpánek, Ivo ; Mazík, Michal ; Grossmannová, Hana ; Jirásek, Pavel ; Holman, Pavel ; Jakubec, Petr ; Fricová, Jana ; Vácha, Zdeněk ; Červenák, Jan ; Dvořák, Martin ; Němec, Václav ; Dušková, Markéta ; Fogaš, Igor ; Bačovský, Jiří
Metodika poskytuje doporučení pro správnou praxi dlouhodobého uchovávání předmětů kulturní povahy v paměťových institucích. Předkládá logickou osnovu zohledňující důležité aspekty související s budovami, jejich vnitřním prostředím, bezpečnostními kritérii a možnými riziky, spojenými se způsoby užívání předmětů kulturního dědictví. Metodika si klade za cíl též ozřejmit možnosti vyhodnocování vhodnosti stavebních objektů pro dlouhodobé ukládání předmětů kulturní povahy i ze strany jejich majitelů či provozovatelů tak, aby bylo možné predikovat jejich vliv na uložené fondy a udržitelnost provozu.
