Thin magnesium-nickel films grown on Mo( 110) under ultra-high vacuum conditions were hydrogenated with atomic H and studied by high-resolution core-level photoelectron spectroscopy ( PES) and thermal desorption spectroscopy (TDS). We show spectroscopic evidence for reversible hydrogen storage and clear evidence that no Mg segregation or desorption occurs when hydrogen is desorbed from the film. D

In an open, randomized prospective clinical trial the analgesic effect of indomethacin and ketobemidon was compared in 67 patients with acute cholecystitis (28 received 5 mg ketobemidon and 39 received 50 mg indomethacin). Both drugs showed a good and significant pain relief, exhibiting no significant difference in the analgesic effect and no serious adverse reactions. It was concluded that indome

The title compound, lithium potassium dialuminium diger-manium octaoxide dihydrate, (K,Li)-(Al,Ge)-GIS (GIS is gismondine), is the result of a 50% Li+ exchange into the K-(Al,Ge)- GIS structure. The (K,Li)-(Al,Ge)-GIS structure was determined from a 4 x 4 x 2 m m octahedral single crystal at the ESRF synchrotron X-ray source. The ion exchange results in a symmetry transformation from I2/a for K-(A

A solvent-free microextraction technique based on liquid-gas-liquid microextraction was investigated for the extraction and preconcentration of 2,4-di-tert-butyl phenol from aqueous samples. In this study 16 mu L NaOH 1 M as acceptor phase was introduced in the lumen of a polypropylene hollow fiber, with one of its ends heat-sealed. A small piece (about 2 cm) of metallic wire was used to seal the

Context: Ghrelin is a novel hormone produced mainly in the gastric body. Hitherto, mapping studies of ghrelin cells covering the entire gastrointestinal (GI) tract in humans have been lacking. Furthermore, the phenotype of extragastric ghrelin cells is not known. Objective: The objective of the study was to perform a detailed mapping with specimens from all parts of the GI tract, and colocalizatio

Air flow rate through filters and face masks is one important determinant of the final protection factor of a respiratory protective device in use. Respiratory minute volumes and instantaneous breath flow rates were measured in eight subjects during treadmill work using three types of filtering respirators and one control breathing mask. Work comprised five consecutive bouts of walking at 5 km/h w

Effects of core-level degeneracies on X-ray photoemission spectra are considered theoretically and computationally. Processes within each degenerate sub-level manifold are treated by a leading-order cumulant approximation, and processes which connect spin-orbit or crystal-field split levels to leading order in the core-electron self-energy. The cumulant approximation is consistent with earlier asy

The relation between donor alanine aminotransferase (ALT) and recipient post-transfusion hepatitis (PTH) non-A, non-B was studied in patients tested before and 6 and 12 weeks after transfusion. The minimum ALT criterion for PTH was 105 IU/l (greater than 2.5 times the upper normal of 42 IU/l). In 8.8% of donors, ALT was greater than 42 IU/l, and in 2.3% ALT was greater than 63 IU/l, i.e., 1.5 time

Popular Abstract in Swedish Syftet med avhandlingen är att studera och analysera en historisk epok och dess människor genom deras materiella kultur och hur de sociala relationerna har manifesterats i rummet. Som fokus fungerar den medeltida biskopsstaden Linköping, en plats som skiftat utseende, funktion och betydelse genom olika perioder, men hela tiden med starka ideologiska uttryck. Linköping Is it possible to understand a society and a certain place that is long since gone? The aim of this thesis is to study and analyse a historic period and its people through the remains of their material culture, the social relations and how these were materialized in an urban setting. The main subject of the empirical study, the medieval episcopal town of Linköping, has shifted out-look, function a

Objectives: To develop evidence based recommendations for the management of hand osteoarthritis (OA). Methods: The multidisciplinary guideline development group comprised 16 rheumatologists, one physiatrist, one orthopaedic surgeon, two allied health professionals, and one evidence based medicine expert, representing 15 different European countries. Each participant contributed up to 10 propositio

Cost effectiveness is an important factor to consider when choosing between various hand surgical interventions. Health utility measures can be used to determine cost effectiveness. The SF-6D is a health utility index derived from 11 items of the SF-36 quality of life questionnaire; values range from 0.296 to 1.0 (“perfect” health). We evaluated the validity of the SF-6D in patients with carpal tu

BACKGROUND: The interpretation of clinical trials and efforts directed at reducing the worldwide burden of coronary disease must take regional differences into account. This study examined the regional differences in baseline characteristics, treatment, and outcome in patients presenting with ST elevation myocardial infarction (STEMI) who were entered into the Magnesium in Coronaries (MAGIC) trial

The sequence of the mitochondrial (mt) DNA of the horse (Equus caballus) was determined. The length of the sequence presented is 16 660 bp. This figure, however, is not absolute due to pronounced heteroplasmy caused by variable numbers of the motif GTGCACCT in the control region of different molecules. Boundaries of the 13 peptide-coding genes were determined by the presence of start and stop codo

När någon säger "kvinna" är det inte säkert att alla tänker på samma sak. Vårt kön, men också kroppen, har inte bara fysiologiska/biologiska egenskaper utan utgör också en kulturell konstruktion och är därmed föränderlig.
