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
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
Popular Abstract in Swedish Ämnet för denna sammanläggningsavhandling är lärande i en svensk konsthögskolekontext. Det finns sparsamt med forskning som avser högre utbildning i fri konst, och vi vet inte mycket om studenternas lärandeprocesser. Vilka kvaliteter utvecklar studenterna under utbildningen, och hur främjas utvecklingen av dessa kvaliteter? I linje med dessa grundläggande frågor, är detThe object of research in this thesis is learning within the context of a practice-based Master of Fine Arts program in visual art in Sweden. Research on learning in visual art practice within higher education is sparse, and we know little of the students’ learning processes. What qualities do the students actually develop during their studies? How may the development of these qualities be support
Popular Abstract in Swedish I en komponent som blir utsatt för en upprepande på- och avlastning, så kallad cyklisk belastning, kan små sprickor initieras och börja växa i materialet. Detta fenomen kallas för utmattning och kan få katastrofala följder, såsom haveri. För att med god säkerhet kunna dimensionera mot utmattning är det viktigt att på en mikro skala förstå de fenomen som ligger bakom sprFatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. In order to accurately dimension against fatigue it is of uttermost importance to have a thorough understanding of the mechanisms behind the
A general overview of the animal styles I and II during the Merovingian Age in Southern Germany.
A differential geometric approach based on the gap metric is taken to examine the uniqueness of solutions of the equations describing a feedback interconnection. It is shown that under sufficiently small perturbations on the Fréchet derivative of a nonlinear plant as measured by the gap metric, the uniqueness property is preserved if solutions exist given exogenous signals. The results developed r
