The aim of this study was to determine the threshold of fracture probability at which interventions became cost-effective in men and women, based on data from Sweden. We modeled the effects of a treatment costing $500 per year given for 5 years that decreased the risk of all osteoporotic fractures by 35% followed by a waning of effect for a further 5 years. Sensitivity analyses included a range of

We examine bosonic atoms that are confined in a toroidal, quasi-one-dimensional trap, subjected to a random potential. The resulting inhomogeneous atomic density is smoothened for sufficiently strong, repulsive interatomic interactions. Statistical analysis of our simulations show that the gas supports persistent currents, which become more fragile due to the disorder.

Popular Abstract in Swedish I denna avhandling belyses varför och hur frågan om arbetarnas bildning blev ett led i såväl borgerlighetens som arbetarklassens formering under andra hälften av 1800-talet. Arbetet utgår från ett teoretiskt perspektiv som bl a innebär att människor aktivt skapar sin klassidentitet i sina vardagliga liv. Undersökningens tyngdpunkt ligger på jämförande analyser mellan sThis dissertation deals with the question of why and how the issue of workers' education came to be part of both bourgeois and working class formation during the second half of the 19th century and how it contributed to the shaping of new social relations. The theoretical perspective is based on the concept of hegemony indicating that a leading class has to establish and maintain its leadership by

With recent findings of substantial amounts of B in rock-forming minerals, it has become evident a need exists for microprobe techniques allowing quantitative B determinations in minerals. A microprobe method based on the nuclear reaction B-11(p,alpha)2alpha has the potential to become a powerful tool for analyses of minerals with B contents spanning a wide concentration range. In this paper, we p

Small crystallites form when finite quantal systems are set highly rotating. This crystallization is independent of the statistics of the particles, and occurs for both trapped bosons and fermions. The spin degree of freedom does not change the tendency for localization. In a highly rotating state, the strongly correlated bosonic and fermionic systems approach to that of classical particles.

The interest for effective preventive strategies for slips and falls in growing.Much remains to be done however to prevent slips and falls in the traffic environment.Using an appropriate anti-slip device may reduce the risk of slips and falls on different surfaces outdoors during winter. The aim of this study was to evaluate the best anti-slip devices of different designs in the Swedish market on

Popular Abstract in Swedish Ett stort problem med samhällsvetenskapliga studier som på ett eller annat sätt behandlar informationsteknologins följder är att det är svårt, ibland helt omöjligt, att jämföra resultat och slutsatser. Detta beror delvis på att man behandlar ”informationsteknologi” eller ”IT” på så olika vis. Någon kanske konceptualiserar ”IT” som att vara en viss typ av hemsidor, andraThis work has two main ambitions. First, we will develop a generic framework which, properly used, can drastically reduce the intrinsic complexity of the continually evolving IT-environment, making it less unwieldy. That should prove advantageous for anyone trying to analyse social aspects of the moving target that is classified as "IT". Using (and at the same time demonstrating) his framework, w

Conventionally, epoxidation of unsaturated fatty acids has been studied either with titrimetric methods or in a lengthy procedure involving derivatization followed by gas chromatography (GC). We have developed a more rapid and descriptive analysis procedure for the substances using high performance liquid chromatography (HPLC) with evaporative light scattering detection (ELSD). Chemo-enzymatic epo

There is a considerable amount of data in humans showing that patients who cannot take in nutrients enterally have more organ failure in the intensive care unit, a less favourable prognosis, and a higher frequency of septicaemia, in particular involving bacterial species from the intestinal tract. However, there is little evidence that this is connected with translocation of bacterial species in h

Carbon-14 levels in the vicinity of the Lithuanian nuclear power plant Ignalina have been investigated. During 2001-2004, approximately 70 samples were collected and analysed using accelerator mass spectrometry. The study included samples of leaves, grass, moss, soil and aquatic plants, covering a distance up to 32 km from the power plant. The highest C-14 specific activities were found in soil sa

Background & Aims: Human milk is believed to contain biological factors involved in the regulation of newborn growth, including brain development. Recently, it has also been shown to contain the calcium-binding S100B protein, regarded as a neurotrophic factor. The present study investigates the concentrations of this protein in colostrum, human milk at different levels of maturation and in mil
