In a randomized study of 100 patients having displaced femoral neck fractures (Garden types 34), we compared internal fixation using 2 von Bahr screws (n = 53) with a bipolar Variokopf prosthesis (n = 47). The duration of surgery was shorter and the blood loss was less in the group with screws. Dislocation of the prosthesis occurred in 7/47 patients, all within 4 months. After a minimum follow-up

Introduction. The information behaviour of a group of Swedish computer scientists has been studied over a period of 20 years (1987-2006). Changes in their information seeking are addressed in terms of collaboration levels and discussed as examples of social practice. Method. Qualitative interviewing has been the main method for data collection. Analysis. Interview transcripts have been content ana

Ozone in the atmosphere, mainly in the stratosphere, absorbs most of the ultraviolet-B (wavelength 280-315 nm) radiation from the sun, which can destroy DNA and other biologically important molecules and, thereby, damage living organisms. Due to the pollution of the atmosphere by humans, the ozone layer is presently being depleted, more rapidly at higher latitudes than at lower, and more rapidly o

Vegetation patterns of subalpine gully-head mires were investigated in the flat-topped Lammerlaw and Lammermoor Ranges, South Island, New Zealand. Two intensively studied mires each consist of a series of peaty terraces and scarps. Terraces may contain pools, elongated downslope in the narrow, lower altitude mire, but across slope in the broader, upper mire. A crest occurs on some terrace lips, an

Gasification is an important option for the swift implementation of biomass combined heat and power. processes in the Danish energy supply system. Tar-water produced by the gas-cleaning system of gasifiers may contain substances toxic to nitrifying bacteria. As the gasification plants are small and often located in the catchment area of small wastewater treatment plants, discharge of the tar-water

Objectives We sought to replicate the association between the kinesin-like protein 6 (KIF6) Trp719Arg polymorphism (rs20455), and clinical coronary artery disease (CAD). Background Recent prospective studies suggest that carriers of the 719Arg allele in KIF6 are at increased risk of clinical CAD compared with noncarriers. Methods The KIF6 Trp719Arg polymorphism (rs20455) was genotyped in 19 case-c

Asymmetrical-flow field-flow fractionation combined with multiangle light scattering and refractive index detection has been revealed to be a powerful tool for starch characterization. It is based on size separation according to the hydrodynamic diameter of the starch components. Starch from a wide range of different botanical sources were studied, including normal starch and high-amylose and high

The purpose of this study was to determine long-term risk factors for substance-induced and primary psychosis after release from prison.

Abstract in UndeterminedLeaf area index (LAI) and canopy coverage are important parameters when modelling snow process in coniferous forests, controlling interception and transmitting radiation. Estimates of LAI and sky view factor show large variability depending on the estimation method used, and it is not clear how this is reflected in the calculated snow processes beneath the canopy. In this s

In the period 2009–2011, Member States discussed whether the EU should increase its emissions reduction target for 2020 beyond the existing 20%. This discussion has not resulted in any agreement, the different actors being deeply divided between those calling for a step-up to a higher target (for instance 30%) and those opposed to any kind of increase. The division can be seen as a result of a con

The number of athletes with disabilities participating in organized sports and the popularity of the Paralympic Games is steadily increasing around the world. Despite this growing interest and the fact that participation in sports places the athlete at risk for injury, there are few studies concerning injury patterns, risk factors, and prevention strategies of injuries in disabled athletes. In thi

Navigate PD was an educational program established to supplement existing guidelines and provide recommendations on the management of Parkinson's disease (PD) refractory to oral/transdermal therapies. It involved 103 experts from 13 countries overseen by an International Steering Committee (ISC) of 13 movement disorder specialists. The ISC identified 71 clinical questions important for device-aide
