1. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold
Abstract : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. READ MORE

2. Single fluid inclusion analysis using ToF-SIMS : Implications for ancient Earth biodiversiy and paleoenvironment studies
Abstract : When and how life first emerged on the Earth is an area of intense research. Signs of the first life on Earth, including morphological fossils, are scarce and hard to interpret. An alternative approach is to study organic biomarkers, which are molecular fossils commonly considered as bona fide biosignatures. READ MORE

3. Growth and removal of inclusions during ladle refining
Abstract : The overall purpose of this thesis work has been to further our understanding of the growth and removal of inclusions in gas- and induction-stirred ladles. The primary focus has been on alumina inclusions.Growth mechanisms were studied using data from fundamental mathematical models of gas- and induction-stirred ladles. READ MORE

4. Superoxide dismutase 1 and amyotrophic lateral sclerosis
Abstract : Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons in the spinal cord, brain stem and motor cortex, leading to paralysis, respiratory failure and death. In about 5% of ALS cases, the disease is associated with mutations in the CuZn-superoxide dismutase (hSOD1) gene. READ MORE

5. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming
Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE
