The orbit space of groupoids whose C∗C^*-algebras are GCR

Let $G$ be second countable locally compact Hausdorff groupoid with a continuous Haar system. We remove the assumption of amenability in a theorem by Clark about GCR groupoid $C^*$-algebras. We show that if the groupoid $C^*$-algebra of $G$ is GCR then the orbits of $G$ are locally closed.Comment: 1

A prospective study of the use of antibiotics in the Emergency Department of a Chinese University Hospital

Background: Antibiotics are one of the most widely misused group of medicines. The aim of this study was to investigate the use of antibiotics in one of the paediatric emergency departments in China. Methods: We performed a prospective, cross-sectional study of antibiotic use in the paediatric emergency room of West China Second University Hospital. A total of 500 consecutive patients from March 25 to April 3 2013 were included. Clinical details of the patients were also collected in order to analyse antibiotic use. Key findings: The median age of patients was 2 years 2 months. The five most common conditions seen in the emergency department were wheezy bronchitis, upper respiratory tract infections, tonsillitis, pneumonia and diarrhoea. A total of 311 children (62%) received antibiotics. The antibiotics prescribed were predominantly cephalosporins and penicillins. More than one antibiotic was used in 51 patients. In total, 75% of the antibiotics prescribed were cephalosporins. More than three-quarters of the young children with wheezy bronchitis received antibiotics. Antibiotic use for children with an upper respiratory tract infections or tonsillitis was greater than the 20% maximum recommended by the European Surveillance of Antimicrobial Consumption. Conclusions: The majority of children attending the emergency department received antibiotics. For many of the conditions, the use of antibiotics was inappropriate

Pub environment

An audio-visual model a pub in Oldenburg, Germany. The model has been created for a highly accurate acoustic rendering over loudspeaker arrays and headphones and for visual representation in virtual reality. The package encompasses an accurate spatial geometric model of the pub, which can be used for acoustic simulations, and a visual model for virtual reality. It further includes a definition of an acoustic scene for the purpose of audiology and hearing research together with the associated measurements of the acoustic impulse responses using a binaural recording system (binaural room impulse responses), a tetrahedral and omnidirectional microphones. The 3D model was developed by Maartje Hendrikse
