A study is presented about the effects of three glazing colour types (blue, neutral, bronze) on daylight quality, arousal and switch-on patterns for electric lights. This study was carried out using a scale model (1:4) of an office room, where subjective evaluations of the luminous conditions were performed by 36 participants (mean age 23.8 years) with their upper bodies immersed in the model. The

The purpose of the study was to develop a method for analysis of diffusion parameters along white matter (WM) tracts, using spatial normalization based on anatomical landmarks, and to introduce the apparent area coefficient (AAC). The method's applicability was tested in the inferior fronto-occipital fasciculus (IFO) in patients with progressive supranuclear palsy (PSP) and healthy controls (HCs).

Arctic ecosystems play a key role in the terrestrial carbon cycle. Our aim was to combine satellite-based normalized difference vegetation index (NDVI) with field measurements of CO2 fluxes to investigate changes in gross primary production (GPP) for the peak growing seasons 1992-2008 in Rylekaerene, a wet tundra ecosystem in the Zackenberg valley, north-eastern Greenland. A method to incorporate

Background: Excess body weight, physical activity, smoking, alcohol consumption and certain dietary factors are individually related to colorectal cancer (CRC) risk; however, little is known about their joint effects. The aim of this study was to develop a healthy lifestyle index (HLI) composed of five potentially modifiable lifestyle factors healthy weight, physical activity, non-smoking, limited

Housing was a backbone of the Danish welfare state, but this has been profoundly challenged by the past decades of neoliberal housing politics. In this article we outline the rise of the Danish model of association-based housing on the edge of the market economy (and the state). From this, we demonstrate how homes in private cooperatives through political interventions in the context of a booming

Aim: This study investigated the relationship between sexual debut before 14 years of age and socio-demographics, sexual experience, health, experience of child abuse and behaviour at 18 years of age. Methods: A sample of 3432 Swedish high school seniors completed a survey about sexuality, health and abuse at the age of 18. Results: Early debut was positively correlated with risky behaviours, such

It is important to understand the role that different predators can have to be able to predict how changes in the predator assemblage may affect the prey community and ecosystem attributes. We tested the effects of different stream predators on macroinvertebrates and ecosystem attributes, in terms of benthic algal biomass and accumulation of detritus, in artificial stream channels. Predator richne

In Order to differentiate the semiotic capadties of animals and human beings we need to understand more exactly wfaat these properties are. Instead of identifymg all vehicles of meaning with signs, we certainly have to spedfy the notion of sign, but it will also be necessaty to provide an inventory of other kinds of meaning, staiting out from perception, and going through a number of intermediate

Background and aim of the study: The logistic EuroSCORE and STS score have been used for the selection of suitable TAVI patients, but their predictive ability is unsatisfactory. The study aim was to evaluate the performance of the EuroSCORE II in predicting 30-day mortality after TAVI in comparison to the logistic EuroSCORE and STS scoring systems. Methods: Between January 2008 and April 2013, a t

Purpose: To evaluate the dose distribution of a 120-MeV laser-plasma accelerated electron beam which may be of potential interest for high-energy electron radiation therapy. Methods: In the interaction between an intense laser pulse and a helium gas jet, a well collimated electron beam with very high energy is produced. A secondary laser beam is used to optically control and to tune the electron b

Copolymeric NiPAM:BAM nanoparticles of varying hydrophobicity were found to retard fibrillation of the Alzheimer's disease-associated amyloid beta protein (A beta). We found that these nanoparticles affect mainly the nucleation step of A beta fibrillation. The elongation step is largely unaffected by the particles, and once the M is nucleated, the fibrillation process occurs with the same rate as

Purpose: Diagnosis of chronic atrophic fundal gastritis (CAFG) is important to understand the pathogenesis of gastric diseases and assess the risk of gastric cancer. Autofluorescence imaging videoendoscopy (AFI) may enable the detection of mucosal features not apparent by conventional white-light endoscopy. The purpose of this study was to estimate the diagnostic ability of AFI in CAFG. Methods: A

P>The robust generation of midbrain dopamine neurons from embryonic stem cells and patient-specific induced pluripotent stem cells is a prospective tool for the development of new drugs and cell based therapies, and investigations into the aetiology of Parkinson's disease. To achieve this, it is crucial to identify the fate-determining regulatory factors that influence dopamine cell fate decision

In a forested near-urban location in central Germany, the CCN efficiency of particles smaller than 100 nm decreases significantly during periods of new particle formation. This results in an increase of average activation diameters, ranging from 5 to 8% at supersaturations of 0.33% and 0.74%, respectively. At the same time, the organic mass fraction in the sub-100-nm size range increases from appr

Cross-sectional studies have shown that patients with primary hip osteoarthritis (OA) have higher bone mineral density (BMD), higher BMI, lower lean body mass, and higher fat content. But it is unknown if this phenotype is found also in patients with knee OA and if it precedes OA or manifests as a result of the disease.
