Purpose– The purpose of this paper is to determine the optimal office lighting use with different types of lighting controls to achieve energy savings and provide visual comfort for individuals.Design/methodology/approach– A case study and field measurements were carried out in 18 single-occupancy offices in Sweden where six different lighting controls were investigated. Occupancy and daylight hou
Intensive surveys of staging and wintering diving ducks in the Öresund area,southern Sweden, were undertaken during the winters 1995/96, 1996/97 and1997/98 as a part of the Environmental Impact Assessment (EIA) related to theestablishment of a Fixed Link (bridge–tunnel–artificial island) between Swedenand Denmark. Monitoring of the benthic fauna made it possible to compare thecalculated food requi
Magnetkameran är en fantastisk medicinsk bildutrustning som kan producera detaljerade bilder av insidan av kroppen. Förutom bilder av vävnaden och dess struktur så kan magnetkameran också användas till att mäta olika egenskaper hos vävnaden. Om en vävnadsegenskap mäts i varje bildpixel så kan den resulterande bilden (parameterkartan) visas och användas för medicinsk bedömning, vilket kallas för kvThe magnetic resonance imaging (MRI) scanner is a remarkable medical imaging device, capable of producing detailed images of the inside of the body. In addition to imaging internal tissue structures, the scanner can also be used to measure various properties of the tissue. If a tissue property is measured in every image pixel, the resulting property image (the parameter map) can be displayed and u
We have proposed that it is sufficient to provide a simple substratum on which regenerating axone may traverse a gap in a peripheral nerve. To test this hypothesis we set up a new experimental model in which sutures where used to bridge a 10 mm long defect in a peripheral nerve. A defect was created bilaterally in 25 rat sciatic nerves. The cut ends of the nerve were joined by three laps of a cont
This article addresses the dilemmas concerning legislation, individual autonomy and the reality of everyday life for people coping with dementia. We describe and analyse decision-making in relation to older people with dementia in Sweden, within the area of social work regulated by the Social Services Act and the Parental Act. Swedish legislation is based on the individual’s autonomy and capacity
Ammonia (NH3) has been identified as a potential hydrogen-carrier fuel with no carbon emissions. Non-intrusive in-situ NH3 diagnostic technique is of great interest. In this work, femtosecond two-photon laser-induced fluorescence (fs-TPLIF) was demonstrated in NH3/N2 mixtures to achieve NH3 measurements. A femtosecond laser at 305 nm was used for two-photon excitation of NH3 to its excited state (
The application of feedback control to computing systems is a promising research area, but has to date been hindered by the almost unanimously perceived complexity in creating control-oriented system models. Computing systems are in fact considered very hard to describe with dynamic models allowing for simple and powerful control design tools, so that complex ones need bringing in to the detriment
The issue of this presentation is how teachers in the Swedish compulsory school have redefined their jobs as a result of new demands that have emerged during the restructuring in the 1990’s. Earlier, the teachers defined their jobs in terms of good teaching, e.g. transforming the subject matter in order to make it accessible. By using activity theory as a perspective for analysing qualitative data
OBJECTIVE:: Although recent studies have indicated that both orthostatic hypotension and orthostatic hypertension (OHTN) independently predict cardiovascular events, the underlying mechanisms are still debatable. METHODS:: A total of 700 nondiabetic adults (43% men, age 64 years) were examined by orthostatic blood pressure (BP) test, carotid artery ultrasonography, and biochemical tests including
OBJECTIVE: Mediolateral knee movement can be assessed visually with clinical tests. A knee-medial-to-foot position is associated with an increased risk of knee injuries and pathologies. However, the implications of such findings on daily tasks are not well understood. The aim of this study was to investigate if a knee-medial-to-foot position assessed during a clinical test was associated with alte
OBJECTIVES: Alzheimer disease (AD) can now be diagnosed in subjects with mild cognitive impairment (MCI) using biomarkers. However, little is known about the rate of decline in those subjects. In this cohort study, we aimed to assess the conversion rate to dementia and identify prognostic markers in subjects with MCI and evidence of amyloid pathology. METHODS: We pooled subjects from the VU Un
Popular Abstract in Swedish Syn är avgörande för många djurs överlevnad. En väldigt viktig del av ögat är linsen då ljuset fokuseras genom den. I denna studie har jag undersökt hur fisklinser fokuserar ljus. Valet av fiskar som försöksdjur berodde på att de är lätta att skaffa och deras linser är klotformade, vilket underlättar beräkningen av strålgången och linsens optiska egenskaper. Hos fiskar Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. This wavelength dependent focusing leads to chromatic a
Risk and vulnerability assessments (RVA) are vital components of the work conducted by public agencies at different levels, as part of the processes for governing and managing risks in the society. In Sweden, public agencies at all levels are required by legislation to perform risk and vulnerability assessments within their respective area of responsibility. The present paper presents a study of h
Objectives Whether the increased risk of comorbidities, such as cardiovascular disease, in rheumatoid arthritis (RA) can be reverted by particular antirheumatic therapies, or response to these, is unclear but of critical clinical importance. We wanted to investigate whether response to tumour necrosis factor inhibitors (TNFi) translates into a reduced risk for acute coronary syndrome (ACS). Method
It is shown that the ternary system heavy water-heptane-hexadecyl hexaethylene oxide (C16E6) has a stable bicontinuous microemulsion phase down to an exceptionally low concentration at the balanced temperature of 26.8 °C. It is further demonstrated that the ambient gravitational field has an influence on the observed phase equilibria for typical sample sizes (∼1 cm). Direct measurements using a nu
