Cumulative incidence of revision provides a measure of the failure rate of joint replacements and can be used to project demand for revisions. The most commonly applied survival analysis method (Kaplan-Meier [KM]) does not account for competing risks (eg, death). The authors compared the cumulative incidence function (CIF), a competing risks method, with the KM method through application to popula
Fluoroscopic examinations of the upper gastro-intestinal tract and, especially, barium meal examinations, are commonly performed in a majority of hospitals. These examinations are associated both with substantial individual patient doses and contribution to the collective dose from medical exposure. Effective dose estimation for this type of examinations is complicated due to: 1) the necessity to
One of the aims of outdoor lighting in public spaces, such as pathways and subsidiary roads, is to help pedestrians to evaluate the intentions of other people. This paper discusses how a pedestrians' appraisal of another persons' intentions in artificially lit outdoor environments can be studied. We review the visual cues that might be used, and the experimental design with which effects of change
Scholars of international law and international relations largely agree that global governance today, and global environmental governance in particular, is marked by institutional complexity. Environmental policy fields are, to varying degrees, governed by a plurality of institutions with different levels of legalization, membership, and jurisdictional scope, and with different degrees of coherenc
The demographic changes in society with growing numbers of elderly subjects will inevitably increase admission rates to acute emergency departments (AMU). Early discharge might augment emergency readmissions due to a relapse in medical conditions. Our aim was to study precipitating factors in frail elderly patients who got the diagnosis 'lack of community support' after initial medical examination
An experimental setup for characterizing the magnetic field of MRI RF coils was proposed and tested. The setup consisted of a specially configured 3D-printer, a network analyzer and a mid-performance desktop PC. The setup was tested on a single loop RF coil, part of a phased array for fetal imaging. Then, the setup was used for determining the magnetic field characteristics of a high-pass birdcage
Att bli förälder är en stor livsomställning och föräldrars upplevelse av första tiden efter att barnet fötts påverkas bland annat av den information och förberedelse de får under graviditeten. Depression efter förlossningen drabbar cirka 10 % av alla föräldrar, något som även kan påverka anknytningen till barnet och därigenom barnets hälsa och utveckling. Tidigare forskning har visat att nyblivna Parents often feel inadequately prepared for challenges of early parenthood. This thesis aimed to develop an evidence-based programme for antenatal preparation for early parenthood and to test its feasibility. The Medical Research Council’s framework for development and evaluation of complex interventions was used to design the three studies.Interviews were conducted with first-time parents; 18 mo
This paper reports a study of pupils’ experiences of media and information literacy education in five Swedish schools by answering the following overarching question, what roles do the teaching of information seeking and critical assessment of information play for pupils in their school-work as well as in their everyday life? Pupils in ninth grade were asked to fill in a questionnaire regarding th
This thesis explores the right to access employment for persons with disabilities under the UN Convention on the Rights of Persons with Disabilities. It seeks to ascertain what entitlements and for whom this right entails. Given the central conceptual role disability and equality play in the Convention, this thesis explores the prevailing models of understanding of both disability and equality. Af
In order to halt current resource depletion and minimise environmental destruction, we need to reduce our dependency on virgin raw materials. There is a growing political consensus in the EU that we have to move away from our current linear economic system to one that is based on closing material loops, a circular economy. There is therefore a great need for new business models based on for exampl

Today, biofuel industries are emerging in forms that can offer some unique opportunities to help combating climate change, cope with the emerging energy crisis and also serve to advance rural development for millions of rural poor who could benefit from this new development. Rural opportunities are expected to occur through: a) the generation of new employment and income opportunities and increase

High-intensity neutron beams, such as those available at the European Spallation Source (ESS), provide new opportunities for fundamental discoveries. Here, we discuss a novel Ramsey neutron-beam experiment to search for ultralight axion dark matter through its coupling to neutron spins, which would cause the neutron spins to rotate about the velocity of the neutrons relative to the dark matter hal
Objective: To estimate the size of regression to the mean (RTM) for common patient-reported outcomes in trials for knee osteoarthritis (OA). Design: Longitudinal cohort study; we included participants of the Osteoarthritis Initiative who fulfilled typical inclusion criteria for enrolment in a trial. These included: age 40–79 years, symptomatic knee OA, Kellgren-Lawrence grade 2–3, use of pain medi
In medical and biomedical education, traditional teaching methods often struggle to engage students and promote critical thinking. The use of AI language models has the potential to transform teaching and learning practices by offering an innovative, active learning approach that promotes intellectual curiosity and deeper understanding. To effectively integrate AI language models into biomedical e
