1. Physical activity and myocardial infarction : Epidemiological studies on the association between various types of physical activity and the risk of myocardial infarction, including certain aspects of methodology
Sammanfattning : .... LÄS MER
2. Bone mass and physical activity
Sammanfattning : Abstract Weak and osteoporotic bones in old age are an increasing cause of mortality and painful physical impairment of the elderly, especially in the western world. Bone mineral accrual during childhood and adolescence is thought to play a vital role in preventing osteoporosis. LÄS MER
3. Physical Activity and Cardiovascular Disease
Sammanfattning : The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. LÄS MER
4. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment
Sammanfattning : Two industrial studies and one set of lab scale trials have been done. In addition, a theoretical study has been done. The main focus has been on non metallic inclusion composition during the ladle refining operation in industrial steel production. Sampling has been done together with careful inclusion determination.
