Traditionally, occupational injury rates are measured as number of injuries per amount of work. In contrast, we propose that for certain purposes of economic policy, a more relevant measure could be obtained by considering them as production costs and comparing them with output. This was accomplished by replacing “hours worked” in the traditional formulae for estimating accident risk with “value a
PURPOSE: We evaluated whether biennial screening with prostate specific antigen (PSA) only is sufficient to detect prostate cancer while still curable. MATERIALS AND METHODS: In Goteborg, Sweden 9,972 men 50 to 65 years old were randomized to PSA screening. During 1995 and 1996 these men were invited for a first PSA screening and invited during 1997 and 1998 for a second screening. The screening p
Background and aim: Diagnosis of coeliac disease is based on the demonstration of enteropathy in a small bowel biopsy. Correct diagnosis is of utmost importance, since the need for dietary management is life long, and inadequate treatment may lead to potentially serious complications. The Swedish Working Group for Paediatric Coeliac Disease has published guidelines for the diagnosis of childhood c
Experience gained from cooperation between dermatologists and vascular surgeons in 177 patients evaluated at a joint leg ulcer clinic is reported. Patients were divided into two subgroups: (i) 86 patients with healed ulcers and (ii) 91 patients with ongoing therapy-resistant ulcers. Venous insufficiency was the most common etiology in both subgroups (87% and 55%, respectively). Of previous therapy
st nematode-trapping fungi are dependent on specific hyphal structures on or in which nematodes can be trapped mechanically or by adhesion. These structures are a prerequisite for the ability of the fungus to invade a host and are thus crucial for survival as well as virulence. The diversity of trapping structures is large and highly dependent on the environment of the fungus. Within one single sp
The production of single- and multi-photon events has been studied in the reaction e(+) e(-) --> gamma(gamma) + invisible particles. The data collected with the DELPHI detector during the years 1999 and 2000 at centre-of-mass energies between 191 GeV and 209 GeV was combined with earlier data to search for phenomena beyond the Standard Model. The measured number of light neutrino families was cons
Variability in cover of five field layer species was recorded during ten consecutive years in thirty permanent plots within a south Swedish Carpinus betulus forest. The studied species were Oxalis acetosella, Lamium galeobdolon, Stellaria holostea, Hedera helix and Holcus mollis. We observed great interannual variability in cover percentage of all studied species with 76% out of all year-to-year d
The anthology Möten och metamorfoser ("Meetings and metamorphoses")consists of intermedial and interartial analyses.
We have demonstrated in sensitized rats that the immediate response to endointestinal challenge with allergen (10(-6) M ovalbumin) is characterized by mucosal exudation of plasma with little or no concomitant change in the mucosal absorption capacity. The luminal entry of plasma macromolecules also leaves the light microscopic structure and the ultrastructure of the mucosa unaffected. It is possib
The complete genome sequences of cyanobacteria and of the higher plant Arabidopsis thaliana leave no doubt that the plant chloroplast originated, through endosymbiosis, from a cyanobacterium. But the genomic legacy of cyanobacterial ancestry extends far beyond the chloroplast itself, and persists in organisms that have lost chloroplasts completely.
Anti-leukotriene therapy represents a new principle in asthma treatment. As elite athletes can have asthma, this double-blind, placebo-controlled, randomised cross-over study investigated the effect of 10 mg oral montelukast, a specific and potent cysteinyl leukotriene receptor antagonist, on physiological responses to submaximal and maximal aerobic exercise at -15 degrees C in 14 non-asthmatic hi
As an extension of previous studies on modeling and identification of nonlinear dynamic load models, this letter describes the influence of the normalization in dynamic reactive load models. Using measured data from normal operation, it is shown that the reactive power level, which has previously used as normalization factor is inappropriate. If instead apparent power level is used, the variabilit
