Metastable VO2 complexes in silicon: experimental and theoretical modeling studies

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-

Många vägar leder till artros. Kunskapen om riskfaktorer och sjukdomsmekanismer ökar snabbt

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

Differentiated Knowledge Bases and Varieties of Regional Innovation Systems

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 colour vision in geckos

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

Optical properties of a silver-related defect in silicon

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

Talking Axes, Social Daggers

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 far off Stability - RISING Campaigns

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-

The influence of metal coordination on ligand geometry: the structure of N-t-butyl-2-(diphenylphosphino)benzylammoniumchloride and (N-t-butyl-2-(diphenylphosphino)benzylamine)diacetatepalladium(II)

The structures of N-t-butyl-2-(diphenylphosphino)benzylammoniumchloride and N-t-butyl-2-(diphenylphosphino)benzylaminediacetatepalladium(II) have been determined by X-ray crystallography. The Pd-complex was prepared by treating palladiumdiacetate with N-t-butyl-2-(diphenylphosphino)benzylamine in CH2Cl2 for 4 h at room temperature. The organic compound crystallises in the monoclinic space group P2

Adverse drug reaction reporting by nurses in Sweden

Aim To investigate whether nurses could be a useful tool for improving the reporting rate of adverse drug reactions (ADRs). Furthermore, we wanted to study how physicians working at the study departments would respond to nurses as reporters of ADRs and if the reporting from the nurses affected the reporting rate from the physicians. Methods Three departments of internal medicine and one unit for o

Empirical Studies on the Demand for Monetary Services in the UK

Many economic models contain the single variable 'money'. Money does not exist in the form of a single physical unit and it is common to construct monetary aggregates using the method of simple summations. Monetary aggregation theory lends little or no support to the method of simply summing various monetary asset components up to arbitrary levels of aggregation. In monetary aggregation theory, mo
