In acetonitrile, polyisoprene-b-poly(methyl methacrylate) (PI−PMMA) diblock copolymers form starlike micelles with a dense core of the insoluble PI blocks and a soft solvent-swollen corona of the soluble PMMA blocks. Static and dynamic light scattering experiments in combination with viscosity measurements show that these micelles behave hydrodynamically as hard spheres. The block copolymers are l

What makes a headmaster successful? And what does a successful headmaster do? This article presents some results from a research project – Successful school leadership in different school cultures – that aims to provide answers to these questions. The results derive from interviews, questionnaires, observations and pupils’ essays, and comprise the criteria by which different parties involved in sc

This paper summarises the major recommendations and conclusions of the third Forum of the European Network on Energy Research (ENER) which took place in June 2002 in Budapest. The major perceptions of this meeting as well as the most important conclusions and recommendations for energy policy makers are compiled in this summary. The statements compiled in the following represent a consensus within

We measured the intracapsular pressure preoperatively in 18 hips (17 patients) before revision of a total hip arthroplasty because of aseptic loosening. Distension of the joint capsule was measured with sonography in 13 cases. In extension, the mean intracapsular pressure was 26 (0-60) mmHg, in extension and inward rotation it was 159 (24-280) mmHg, in extension and outward rotation it was 30 (3-6

The charmed strange baryon Xi(c)(0) was searched for in the decay channel Xi(c)(0) -> Xi(-)pi(+), and the beauty strange baryon Xi(b) in the inclusive channel Xi(b) -> Xi(-)l(-)(nu) over barX, using the 3.5 million hadronic Z events collected by the DELPHI experiment in the years 1992-1995. The Xi(-) was reconstructed through the decay AT, using a constrained fit method for cascade decays. An iter

Background: Within 5 years following radical prostatectomy, between 15 and 60% of patients with pT3 prostate carcinomas show an increasing prostate-specific antigen (PSA) as a sign of local and/or systemic tumour progression. Adjuvant radiotherapy (RT) for positive margins (RI) aims to reduce residual tumour cells in the prostatic bed, thus possibly reducing the biochemical progression rate. Apart

The aim of this study was to test whether environmental enrichment alters the status and responsiveness of pituitary-adrenocortical and sympathetic-adrenomedullary hormones in rats. Previous studies have shown that rats kept in an enriched environment differ from those kept in standard cages in dendritic branching, synaptogenesis, memory function, emotionality and behaviour. In male Wistar rats ke

The effect of betamethasone on choroid plexus transport and CSF formation in rabbits was studied. Following 5 days of daily treatment with betamethasone the CSF production rate was reduced by 43% as measured by ventriculo-cisternal perfusion with radioactive inulin. Accordingly, the Na(+)-K(+)-ATPase activity and the transport capacity in the choroid plexus, measured in terms of choline (10(-5) M)

Popular Abstract in Swedish Avhandlingens syfte är att kartlägga och analysera hur geografiska visioner utgjort diskursiva redskap i en specifik framtidsorienterad process, institutionaliseringen av Öresundsregionen.This thesis is about how geographical visions worked as discursive tools in the institutionalisation of the Öresund Region. The geographical vision is defined as a cognitive set of imagined and material pictures of the future structured as a spatial whole. The geographical vision is, in addition to this, a spaceconfiguration-, power-, and disciplinary - instrument, and, the product of a discursiv

Ribosome recycling factor (RRF) together with elongation factor G (EF-G) disassembles the post- termination ribosomal complex. Inhibitors of translocation, thiostrepton, viomycin and aminoglycosides, inhibited the release of tRNA and mRNA from the post-termination complex. In contrast, fusidic acid and a GTP analog that fix EF-G to the ribosome, allowing one round of tRNA translocation, inhibited
