  4. 2. Bone mass and physical activity

    Author : Anna Nordström; Tommy Olsson; Peter Nordström; Heather McKay; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; physical activity; peak bone mineral density; males; fractures; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Abstract : 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. READ MORE

  5. 3. Physical Activity and Cardiovascular Disease

    Author : Kasper Andersen; Johan Sundström; Claes Held; Frieder Braunschweig; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; epidemiology; cohort study; heart failure; cardiovascular disease; arrhythmias; atrial fibrillation; bradyarrhythmias; sudden cardiac death; heart failure; stroke; ischemic heart disease; cardiovascular death; maximal exercise capacity; muscle strength; skeletal muscle morphology; Kardiologi; Cardiology; Epidemiology; Epidemiologi;

    Abstract : 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. READ MORE

  6. 4. Thermodynamic Aspects on Inclusion Composition and Oxygen Activity during Ladle Treatment

    Author : Johan Björklund; Pär Jönsson; Margareta Andersson; Leiv Kolbeinsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; thermodynamics; inclusions; steel; slag; equilibrium; ladle treatment; vacuum; oxide activity; oxygen activity.; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : 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.

  7. 5. Representing and Reasoning about Complex Human Activities - an Activity-Centric Argumentation-Based Approach

    Author : Esteban Guerrero Rosero; Helena Lindgren; Juan Carlos Nieves; Chris Reed; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex activity; Argumentation Theory; Activity Theory; Logic programming; Knowledge representation; Common-sense reasoning; Artificial Intelligence; business data processing; administrativ databehandling;

    Abstract : The aim of this thesis is to develop theories and formal methods to endow a computing machinery with capabilities to identify, represent, reason and evaluate complex activities that are directed by an individual’s needs, goals, motives, preferences and environment, information which can be inconsistent and incomplete.Current methods for formalising and reasoning about human activity are typically limited to basic actions, e.
