11. Mechanical activation of hematite using different grinding methods with special focus on structural changes and reactivity
Sammanfattning : The mechanical treatment of solids is one of the most common and widely used operations which man has been concerned from the very beginning of the history of civilization. Nowadays, mechanical activation has a wide range of application potentials. LÄS MER
12. Studies on the structure and biogenesis of membrane proteins from the green alga Chlamydomonas reinhardtii
Sammanfattning : The green alga unicellular Chlamydomonas reinhardtii has been used for many years as a model system in the area of photosynthesis. Therefore, the C. reinhardtii chloroplast has been the subject of many studies. In contrast, the mitochondria have received less attention. LÄS MER
13. Influence of green pellet properties on pelletizing of magnetite iron ore
Sammanfattning : Magnetite iron ore green pellets are produced by balling moist concentrates to green pellets, which are then dried, oxidized to hematite, sintered, cooled and transported to steelmaking plants. The existing theory for balling is based on the capillary theory, but its applicability under industrial balling conditions is unclear. LÄS MER
14. Fatigue damage mechanisms in polymer matrix composites
Sammanfattning : Polymer matrix composites are finding increased use in structural applications, in particular for aerospace and automotive purposes. Mechanical fatigue is the most common type of failure of structures in service. The relative importance of fatigue has yet to be reflected in design where static conditions still prevail. LÄS MER
15. Genetic studies of acute lymphoblastic leukemia
Sammanfattning : Acute lymphoblastic leukemia (ALL) is the most common pediatric malignancy, comprising approximately 25% of all childhood cancers. A huge improvement in outcome of children with ALL during the last 20 years has resulted in remission rates exceeding 95% and a 5 year event-free-survival approaching 80%. LÄS MER
