11. Mathematical and Experimental Study on Filtration of Solid Inclusions from Molten Aluminium and Steel
Sammanfattning : Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes.

12. Origin of massive sulfide ores in the Skellefte district, as indicated by fluid inclusions
Sammanfattning : The Proterozoic SkeUefte massive sulfide ore district is confined to a 200 km long belt of a submarine metavolcanic and metasedimentary rock sequence in northern Sweden. It is located between an area of terrestrial metavolcanics in the north and gneisses, migmatites and granites in the south. LÄS MER
13. ToF-SIMS as a tool for analysing organic material in geological samples -Fluid inclusions and beyond
Sammanfattning : In situ analysis of organic material in rocks has potential to answer questions in geochemistry, astro- and geobiology. Recently, successful studies which included in situ analyses of geological samples with time-of-flight secondary ion mass spectrometry (ToF-SIMS) were carried out. LÄS MER
14. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters
Sammanfattning : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. LÄS MER
15. Formation of non-metallic inclusions and the possibility of their removal during ingot casting
Sammanfattning : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.
