AimTo investigate whether reduced lung function is a risk factor for developing diabetes. MethodsNon-diabetic men (n = 382) from the population-based cohort 'Men Born in 1914' were examined with spirometry at age 55 years. The cohort was re-examined at 68 years. Diabetes and fasting plasma glucose at follow-up were studied in relation to vital capacity (VC) and forced expiratory volume (FEV1.0) a
Females of many species mate with several males. According to a recent hypothesis, female promiscuity serves to avoid inbreeding. We tested this hypothesis in a polygynous bird, the great reed warbler (Acrocephalus arundinaceus), in which extra-pair fertilization, inbreeding and inbreeding depression occur. However, the extra-pair males and social males did not differ in relatedness to the promisc
Random mesh phases share many common features with the classical lamellar phase in that they are layered phases; but crucially, they possess nonuniform interfacial curvature, since the lamellae are pierced by water-filled pores. The introduction of curvature into the lamellae has been posited as a transitional precursor for other lyotropic phases. In this paper, we show that simple H-2 nuclear mag
We analyzed data from 81 shallow European lakes, which were sampled with standardized methods, for combined effects of climatic, physical, and chemical features of food-web interactions, with a specific focus on zooplankton biomass and community structure. Multiple-regression analysis showed that total phosphorus (TP) generally was the most important predictor of zooplankton biomass and community
N-Alkylation of amino acid methyl esters with 9,10-bis-chloromethylanthracene, followed by methyl ester hydrolysis, yielded water-soluble amphiphilic amino acid-anthracene conjugates. In NMR-titration experiments, a L-arginine-anthracene conjugate was demonstrated to recognize p-nitrophenyl glycosides and sialylated oligosaccharides in D2O in a manner sensitive to the carbohydrate structure.
This paper is concerned with the permittivity reconstruction of inhomogeneous dielectric media. The method applies to profiles that vary with depth only, i.e. it provides a one-dimensional profile reconstruction. The data are collected and analyzed in the time domain. In the first part of the paper the theory of the method is reviewed. It is showed that a finite time trace of reflection data suffi
A hybrid sodium heat pipe receiver has been developed within the project HYHPIRE, funded 50% by the European Commission. The hybrid receiver was designed for the SBP/LCS 10-kWel dish/Stirling system with the SOLO-161 Stirling engine. Design of the heat pipe receiver and combustion system are described in this paper The system has been tested successfully in all operation modes. Results and experie
San Giovenale is a small inland Etruscan community approximately 60 km north of Rome. The site was excavated between 1956 and 1965 and the focus of the research has been aimed at the archaic period as well as the proto- Villanova period. The Late Etruscan period has up to now been more or less neglected. This resent work is to a large extent based on pottery and one cornerstone of the study is the
By measuring excited state and charge dynamics in blends of an alternating polyfluorene copolymer and fullerene derivative over nine orders in time and two orders in light intensity, we have monitored the light-induced processes from ultrafast charge photogeneration to much slower decay of charges by recombination. We find that at low light intensities relevant to solar cell operation relatively f
Recently, substantial progress has been made in detection and observation of non-aqueous phase liquids (NAPLs) in the subsurface using different experimental techniques. However, there is still a lack of appropriate direct methods to measure the saturation of NAPL theta(NAPL)). This paper provides a guide for estimating theta(NAPL) and water content (theta(a)) in unsaturated and saturated sand bas
Internationellt har det sedan 1980-talet publicerades en rad offentliga rapporter och utredningar om hur prioriteringar inom sjukvården bör göras. Denna rapport är en översikt över den internationella debatten och en jämförelse med den svenska prioriteringsutredningens förslag.

Traditionally mire ecosystems (especially bogs) have been viewed as stable systems with slow changes in the vegetation over time. In this study the mire Akhultmyren, south-central Sweden was re-investigated in 1997 after 40 yr of continued natural development. The results show a high degree of dynamics in a Sphagnum dominated bog and fen. Altogether 97 vascular plant and bryophyte species were rec
Popular Abstract in Swedish The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. As anThe problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure.

The decay of Bacillus subtilis aprE leader-lacZ mRNA was examined in Escherichia coli wild-type and in mutants deficient in RNase E, RNase G, or both. Two versions of the mRNA were studied: the wild-type mRNA, which has a stem-loop at the 5' end, and a mutant mRNA, with a single-stranded 5' end. The half-life of both transcripts was determined by RNase E, the half-life of the mutant transcript bei
1. The rate of heat production of chemically skinned guinea-pig taenia coli smooth muscle at 25 degrees C was measured using microcalorimetric techniques. 2. Muscle strips were mounted isometrically and incubated in solutions containing MgATP (3.2 mM) and phosphocreatine (PCr, 12 mM), pH 6.9. Activation was obtained by the injection of Ca2+ into the sample compartment of the calorimeter. 3. The he
Eleven arthritic knee joints in seven patients with rheumatoid arthritis were studied before and after intraarticular injection of a corticosteroid preparation. Extensor muscle torque and quantitative electromyography increased on days 7 and 14 after treatment, indicating that muscle function had been inhibited by synovitis. Clinical signs of synovitis, such as pain, range of motion and knee circu
A methodology for the synthesis of novel spiro-cyclohexene bicyclo [2.2.2] octane derivatives, including Claisen rearrangement and ring-closing metathesis (RCM) as key synthetic steps, is described. (c) 2006 Elsevier Ltd. All rights reserved.
