The movement of water in a large (3.5 m(3)) undisturbed sample of 22-year-old municipal solid waste has been modeled using a kinematic wave approximation for unsaturated infiltration and internal drainage. The model employs a two-parameter power expression as macroscopic flux law. The model parameters were determined and interpreted in terms of the internal geometry of the waste medium by fitting

In the literature, there are several different suggestions as to when the first postoperative pin-site care should be carried out to best prevent pin-site infections during the treatment by external fixation. In a cohort study, we compared the use of antibiotics and complications in patients where the theatre dressing was changed during the first postoperative week with patients where the theatre

This paper describes and compares university education and training, the procedures for licensing and the specialist training systems for professional psychologists in the Nordic countries Finland, Norway and Sweden. The interscandinavian and European regulations and agreements affecting mobility are presented. The presented systems are compared to each other and a discussion follows on the topics

The use of mobility devices, such as walking sticks and rollators, increases during the ageing process. Our aim was to explore how very old single-living Swedish women experience the use of mobility devices over time, in relation to everyday occupation. A multiple case study strategy involving quantitative and qualitative data was used. The findings indicate that the use of mobility devices, rolla

Physical bounds on the directivity Q-factor quotient and optimal current distributions are determined for antennas of arbitrary shape and size using an optimization formulation. A variational approach offers closed form solutions for small antennas expressed in the polarizability of the antenna structure. Finite sized antennas are solved using Lagrangian parameters in a method of moments formulati

Popular Abstract in Swedish Ljusets växelverkan med materia är fascinerande och av oerhörd stor betydelse i naturen. Genom vår optiska synförmåga, kan vi och andra organismer få tillgång till en enorm mängd information om vår omgivning. Informationen inkluderar först och främst den geometriska strukturen på världen och dess föremål, men även informationen i färgerna spelar stor roll. Med hjälp av This thesis deals with optical spectroscopy and imaging of complex and strongly scattering turbid media. Focus is mainly placed on three topics, being i) diffuse optical spectroscopy of choroidal tumors, ii) gas spectroscopy in scattering materials using the GASMAS (gas in scattering media absorption spectroscopy) technique, and iii) luminescence diffuse optical imaging and tomography of tissues.
