Both practitioners and research scientists have noted a number of problems regarding measurement activities during the past decade. The problems reported suggest that measurement activities are fragmented both within and across organizations. This article expands on a systems perspective on supply chain measurements and describes how problems can be communicated, understood and managed by developi

The adsorption of NO on Pd(1 0 0) is investigated with high resolution core level spectroscopy and low energy electron diffraction (LEED). Several ordered NO overlayers were observed, in agreement with earlier Studies. Our data clearly show that NO adsorbs in fourfold hollow sites at coverages tip to 0.25 -0.30 monolayer (ML) whereas at 0.5 ML only bridge sites are occupied. By a reinterpretation

Profound hypoglycemia causing the disappearance of spontaneous EEG activity was induced by insulin in rats. For analysis of cerebral cortical concentrations of labile phosphates, glycolytic metabolites and amino acids, the brain was frozen in situ. For microscopic analysis of the corresponding cerebral cortical areas the brain was fixed by perfusion. Hypoglycemia with an isoelectric EEG for 30 and

Microbial growth in coal slurries can be detected if surfactant is present in the samples by analysing the protein concentration after disintegration of the cells. Without surfactant present in the samples, the proteins are readily adsorbed on the coal surfaces. A suitable surfactant is sodium dodecyl sulphate at 0.5 to 1% of the sample volume

The self-assembly behavior of a cationic surfactant (dodecyltrimethylammonium) with DNA as counterion in mixtures of water and decanol was investigated. The phase diagram was established and the different regions of the phase diagram characterized with respect to microstructure by H-2 NMR (D2O), small-angle X-ray scattering (SAXS), and other techniques. The DNA-cationic surfactant aggregate is vir

Background: {alpha}1-Antitrypsin (AAT)-Z deficiency is a risk factor for the development of COPD. Compared to wild-type M, AAT-Z has an increased tendency to polymerize, rendering it inactive as a serine proteinase inhibitor. It has been demonstrated that wild-type M- and Z-deficiency AAT polymers are chemotactic for human neutrophils. However, our own studies dispute a proinflammatory role for po

Aim: To survey the entire population (n = 116) afflicted with severe haemophilia A or B born in Sweden over a 20-y period (1980-1999), and to examine the epidemiological, genetic and clinical aspects of development of inhibitors to factors VIII and IX (FVIII/FIX). Methods: One hundred of the subjects had haemophilia A and 16 had haemophilia B. All of these subjects had received prophylactic treatm

Based on data available at the IAU (International Astronomical Union) Meteor Data Center in Lund 60 precisely reduced photographic Orionid orbits and 17 video observed orbits are analysed. Mean photographic and video orbits are compared with the orbit of comet Halley. The Orionid meteoroid stream structure and radiant motion is studied, and compared with previous visual and photographic studies of

A diagnosis-antibiotic prescribing study initiated by the Swedish Strategic Programme for the Rational Use of Antimicrobial Agents and Surveillance of Resistance was performed in 5 counties in Sweden (total 1,290,000 inhabitants) during 1 week in November 2000. The aims of the study were to analyse diagnoses and antibiotics prescribed for outpatients and to appraise the feasibility of the data col

A straightforward semi-implicit finite-difference method approximating a system of conservation laws including a stiff relaxation term is analyzed. We show that the error, measured in L-1, is bounded by O(root Delta t) independent of the stiffness, where the time step Delta t represents the mesh size. As a simple corollary we obtain that solutions of the stiff system converge toward the solution o

The excitation-decay processes at the F 1s photoabsorption edge in LiF crystal are studied using resonant inelastic x-ray scattering spectroscopy. The Raman-type linear dispersion and the narrowing of the x-ray fluorescence peak are observed at resonant excitation. A theoretical model based on the Kramers-Heisenberg formula describes well the main features in fluorescence spectra and allows one to

Quantification of platelet-bound immunoglobulin is widely used in the evaluation of thrombocytopenia. Several methods have been devised among which labelled ligand-binding assays seem to be most appropriate. In series of adult patients such assays have been shown to be superior in separating immune-thrombocytopenia from thrombocytopenia of non-immune causes. We studied 62 children with thrombocyto
