The overall aim for the present study was to analyze the consequences for reading ability among the children of a computer supported self-regulated learning environment in grade two. By means of a quasi-experimental design in a natural setting, an experimental group (n=39) was compared to a control group from a national sample (n=3409) on reading comprehension. The statistical analyses showed that
The purposes are to validate the noninvasive parameters, QT interval, QT dispersion, Tpeak-Tend interval, and the activation recovery time (ART) for estimation of global dispersion of ventricular repolarization (DVR), and to investigate the changes of repolarization sequence and DVR by altered ventricular pacing sites. The material consisted of 12 patients (Study I) and two series healthy pigs wi
One way to extend the lean-burn limit of a natural gas engine is by addition of hydrogen to the primary fuel. This paper presents measurements made on a one-cylinder, 1.6- liter natural gas engine. Two combustion chambers, one slow and one fast burning, were tested with various amounts of hydrogen (0, 5, 10 and 15%-vol) added to natural gas. Three operating points were investigated for each combus
We present the results of phi meson production in the K+K- decay channel from Au+Au collisions at root s(NN) =200 GeV as measured at midrapidity by the PHENIX detector at Brookhaven National Laboratory's Relativistic Heavy Ion Collider. Precision resonance centroid and width values are extracted as a function of collision centrality. No significant variation from the Particle Data Group accepted v
We report on a combined experimental and theoretical study of the metastable form of the vacancy-dioxygen defect in Si labeled VO2*. Important new experimental observations are the 2 detection of mixed local vibrational modes of VO*(2) in O-16, O-18 co-doped samples, the determination of the position of LVM bands for the negatively charged defect, and an assignment of an acceptor level at about E-
Osteoarthritis does not deserve the term "degenerative joint disease", the course of the disease is characterized by dynamic changes in both synthesis and degradation of cartilage and other joint tissues. At the end stage all tissues of the joint are involved, not only the cartilage. In the early phases of the disease, changes in cartilage metabolism can be detected through assay of biomarkers in
This article introduces a theoretical and analytical framework for discussing regional development and regional advantage with reference to a regional innovation system strategy. It uses the differentiated knowledge base approach to transcend the traditional codified-tacit dichotomy of knowledge, and for providing a trans-sectoral understanding of economic activities. Different regional innovation
Nocturnal animals are said to sacrifice colour vision in favour of increased absolute sensitivity. This is true for most vertebrates that possess a dual retina with a single type of rod for colour-blind night vision and multiple types of cone for diurnal colour vision. However, among the nocturnal vertebrates, geckos are unusual because they have no rods but three cone types. Here, we show that ge
Doping crystalline silicon with silver results in a photoluminescence center with multiplet zero-phonon structure near 778.9 meV. We show that the published assignments of the vibronic sidebands are wrong, with severe implications for the relative transition probabilities of the luminescence transitions from the excited states. At low temperature, most of the luminescence intensity derives from th
Tingen med vilka vi omger oss har symboliska såväl som praktiska innebörder - även bristen på krusiduller på saker är ju i sig en markering. utmaningen för arkeologen är att kunna utläsa hur människor använder sin materiella kultur i sociala manipulationer såväl som för att utföra praktiska göromål. Ett viktigt sätt att kunna utöva makt över tingen är vid tillverkning, där det finns möjlighet att
Nuclear structure studies at CST attracted recently increased interest for the results of present activities as well as for the future project FAIR. A broad range of physics phenomena can be addressed by high-resolution in-beam gamma-ray spectroscopy experiments with radioactive beams offered within the Rare Isotopes Spectroscopic INvestigation at GSI (RISING) project. It combined the EUROBALL Ge-
