  2. 1. Noninvasive evaluation of the effects of coronary artery bypass grafting on myocardial function

    Author : Anders Hedman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Coronary artery bypass grafting; C-reactive protein; dobutamine stress test; Doppler tissue imaging; echocardiography; exercise test; interleukin-6; myocardial peifusion scintigraphy.;

    Abstract : Coronary bypass grafting (CABG) is an effective treatment of patients with coronary artery disease and leads to an improvement in both cardiac symptoms and long-term survival. The effects of CA13G on global left ventricular systolic and diastolic function at rest and during stress, and the long-term effects on right ventricular function and their significance and relation to early graft occlusion and residual myocardial ischemia have however not been fully elucidated.

  6. 4. On synchronization of heavy truck transmissions

    Author : Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. READ MORE

  7. 5. Traces of Movement : Exploring physical activity in societal settings

    Author : Helena Tobiasson; Jan Gulliksen; Yngve Sundblad; Anders Hedman; Åke Walldius; Dag Svanæs; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physical activity; physical literacy; everyday activities; research through design; participatory design and user experience; Människa-datorinteraktion; Human-computer Interaction;

    Abstract : How are we moving, or how much physical activities are present in societal settingssuch as eldercare units, schools, universities and offices? This general question was explored using different design-oriented approaches in four cases, with children,elderly, students and office workers. The results unveil a complexity of the problemarea that initially seemed quite straightforward. READ MORE
