A practical inversion method to calculate the size distribution of colloidal homogeneous particles from small-angle scattering experiments is presented. It is based on the analysis of the deviations of the scattering signal from the Porod law. The resulting inversion formula provides a reliable way to assess complex size distributions such as power-law, multimodal or very broad distributions. It i
Degenerative changes of the lumbar spine may lead to misinterpretation of bone mineral density (BMD) measurements and cause underdiagnosis of osteoporosis. This longitudinal study of 1,044 women, 75 years at inclusion and followed for 10 years, shows that identification of apparent degenerative changes on the dual energy X-ray absorptiometry (DXA) scan can increase the proportion diagnosed. INTR
Multiple nerve branches were created during the regeneration procedure after a nerve injury and such multiple branches are suggested to be used to control, for example, prosthesis with many degrees of freedom. Transected rat sciatic nerve stumps were inserted into a nine mm long silicone tube, which contained four, five mm long, smaller tubes, thus leaving a five mm gap for regenerating nerve fibe
Abstract Background. It has been debated whether or not heparin infusion before or after non-heart-beating donors are declared dead improves the quality of pulmonary grafts. In clinical lung transplantation with heart-beating donors (HBDs) heparin is routinely infused prior to organ harvesting since it is believed to improve pulmonary grafts by minimizing thrombosis formation in the pulmonary graf
We report on the characterization of the new I1011 beamline at the MAX-II storage ring, in the MAX-lab synchrotron radiation laboratory and give examples of first results. This beamline is using an Elliptically Polarizing Undulator source, producing soft x-rays of a variable polarization state. It delivers high flux and high brightness circularly polarized x-rays in the energy range 0.2 to 1.7 keV
Constant volume combustion is studied, using a zero-dimensional model, which is a wide-ranging chemical kinetic simulation that allows a closed system of gases to be described on the basis of a set of initial conditions. The model provides an engine- or reactor-like environment in which the engine simulations allow for a variable system volume and heat transfer both to and from the system. The com
Beginning in 2002, the Department of Health (DoH) n partnership with the National Institute of Clinical Excellence (NICE) began publishing guidelines for the evidenced-based care and treatment of individuals with specific psychiatric disorders. With few exceptions the first-line psychological treatment recommended in all of the guidelines was some form of CBT. The publications of these guidelines
Ever since the end of the 1970s triple-pane windows have been ”standard” in new construction of dwellings and non-residential premises in Sweden. The background was the first oil crisis in 1973, which led to a dramatic sharpening of the thermal requirements regarding the thermal envelope of Swedish buildings. These were introduced in the new building code SBN 75 which was brought into practice in
This thesis, which is based on four original papers, deals with human dendritic cells (DCs) in immunity and allergy. DCs play a key role in the regulation of immune responses by acting as the sentinels of the immune system, specialized in the uptake of a diverse range of antigens. These cells migrate to local lymph nodes and become highly efficient in inducing T cell proliferation, thus inducing a
This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
We investigate a model for buffer management of multi-class traffic into a finite shared buffer. A hierarchy of increasingly stronger linear programming relaxations for this model is proposed. The number of hierarchies equals the number of job classes. Each relaxation in the hierarchy is constructed by projecting the original achievable performance region into a polytope with fewer variables and f
Abstract in UndeterminedIn today's technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Simulations are done in a typical 130 nm technology. Based on the simulation results, the static power in
Sweden is part of a small European minority in the perceived societal gain of PPP. After a pilot PPP project in late 1990’s no additional project has been started in Sweden. Although there is interest from both public infrastructure clients and construction companies the national government has very clearly stated that infrastructure projects should be procured in a traditional way where all fundi
The ATLAS Collaboration at CERN is preparing for the data taking and analysis at the LHC that will start in 2007. Therefore, a series of Data Challenges was started in 2002 whose goals are the validation of the Computing Model, of the complete software suite, of the data model, and to ensure the correctness of the technical choices to be made for the final offline computing environment. A major fe
