Proton-induced X-ray emission, PIXE, is capable of simultaneous quantitative determination of 10-15 elements. An introduction to the physical properties of the method is given and detection limits are shown for a routine analysis of a thin aerosol sample. Examples of applications to both thick and thin samples are presented. Human tooth dentine is analysed for lead, with simple sample preparation,
Maximal oxygen uptake (VO2max) and the amount of type 1 fibers are interrelated but the underlying unifying molecular mechanisms are poorly understood. To explore these mechanisms we related gene expression profiles in skeletal muscle biopsies of 43 age-matched men from published datasets with VO2max and amount of type 1 fibers and replicated some of the findings in muscle biopsies from 154 young

BACKGROUND: The purpose of this study was to investigate awareness among nurses regarding their new role as reporters of adverse drug reactions in Sweden and factors that may influence reporting by nurses. METHODS: In 2007, all nurses were included in the adverse drug reaction reporting scheme in Sweden. A questionnaire was sent to 753 randomly selected nurses in September 2010. RESULTS: Of
Allan Friis tecknar bilden av en absurd institution som hos många elever förmår skapa motvilja till och med mot något så positivt som kunskap.
3G networks and services are being launched all over the world. The basic investments on equipment have already been made according to preliminary traffic forecasts. However, if the mobile data traffic acquires "Internet-like" proportions, network capacity shortage will become a reality in densely populated areas, such as city centers and business parks. In that case, smart antennas may be the sol
In the recently introduced high-contrast transmission version of saturated absorption laser spectroscopy, narrow signals are obtained from dense atomic samples subject to strong pumping. A study of possible systematic shifts of the signals in this domain of rather extreme experimental conditions was performed in order to assess the validity of spectroscopic data obtained with this technique. Certa
Purpose. To investigate how individualised occupation-based interventions with commonly available everyday technology (ET) can compensate for perceived difficulties with daily life tasks after an aquired brain injury (ABI) and improve satisfaction with occupational performance. Method. This intervention study was designed as a multiple case study according to Yin. Ten men and women with an ABI (tr
