Success and Failure of European Settler Farming in Sub-Saharan Africa

This paper ties into the growing literature on the long-term economic implications of historical European settlement, by arguing for the need to properly address the role of indigenous agency in endogenously evolving settlement processes. We develop three comparative case-studies in West, East and Southern Africa to show that the success or failure of European settler farming depended crucially on

Cortical blood flow during head-up postural change in subjects with orthostatic hypotension

Regional cerebral blood flow was measured with the 133-Xenon inhalation method in seven healthy subjects with orthostatic hypotension not due to autonomic failure (i.e. non-neurogenic clinical disorder). Measurements were performed during supine rest and during head-up tilt (70 degrees). All subjects had a consistent drop in systolic blood pressure and the typical symptomatology of orthostatic hyp

Observation Methods and Imaging Techniques. Assessments of physical exposure in repetitive work with focus on neck and upper extremities

Abstract in Danish Observationsmetoder og billeddannelsesteknikker ? vurderinger af den fysiske eksponering i repetitivt arbejde med focus på nakke, skuldre og arme Formålet var at udvikle, etablere og validere observationsmetoder til eksponeringsvurderinger i epidemiologiske undersøgelser af repetitivt arbejde. Et andet formål var at øge kvaliteten af input data til brug i biomekaniske skuldermoObservation methods and imaging techniques - assessments of physical exposure in repetitive work with focus on neck and upper extremities The aim of this thesis was to develop, establish and validate observation methods for exposure assessments in epidemiological studies of repetitive work. A second aim was to increase the quality of input data for biomechanical shoulder models, by reliability an
