Code stability is a matter of concern for three-dimensional (3D) fuel cell models operating both at high current density and at high cell voltage. An idealized mathematical model of a fuel cell should converge for all potentiostatic or galvanostatic boundary conditions ranging from open circuit to closed circuit. Many fail to do so, due to (i) fuel or oxygen starvation causing divergence as local
Modelling is an alternative solution to reduce the cost of water quality monitoring. Commonly, concentration of pollutants is estimated based on limited sampling information. Concentration of ions in rivers can be estimated using modelling strategies that involve statistics and artificial intelligence as well as the understanding of physical processes. Therefore, the performance of feedforward neu
Binary stars form from the same parent molecular cloud and thus have the same chemical composition. Forming planets take building material (solids) away from the surrounding protoplanetary disc. Assuming that the disc's accretion on to the star is the main process that clears the disc, the atmosphere of the star will show abundance reductions caused by the material accreted by the forming planet(s
The semi-quantitative estimate standardised uptake value ratios (SUVR) correlate well with specific binding of the tracer expressed as distribution volume ratios (DVR) for the tau positron emission tomography tracer [18F]AV-1451 uptake and are therefore widely used as proxy for tracer binding. With regard to tracer kinetic modelling, there exists a time point when SUVR deviates minimally from DVR,
The purpose of this paper is to understand the relationship between the formal (governance established in law) and informal institutions (governance not established in law) that underpin the planning, operation and improvement of local and regional public transport, by using case studies of four countries: Britain (more specifically England, outside London); the Netherlands; Germany; and Sweden. T
Purpose: We previously showed that short-term intervention with barley kernel bread (BKB) improved glucose tolerance. However, glucose tolerance was not improved in a subset of individuals (non-responders) who were characterized by a low Prevotella/Bacteroides ratio. The purpose of the present study was to investigate if the baseline Prevotella/Bacteroides ratio can be used to stratify metabolic r
Different vegetables--carrots, peas, Brussels sprouts and spinach--were added to a typical Swedish lunch test meal in portions of 96-164 g. The test and the control meals without vegetables were balanced with respect to digestible carbohydrates (59.7 g) and energy (2000 kJ, 475 kcal), and as far as possible also concerning protein and fat. The added vegetables contained 4.4 g dietary fibre. The me
This review discusses in vivo airway aspects of plasma exudation in relation to current views on epithelial permeability and epithelial regeneration in health and disease. Microvascular-epithelial exudation of bulk plasma proteins characteristically occurs in asthmatic patients, being especially pronounced in those with severe and exacerbating asthma. Healthy human and guinea pig airways challenge
Purpose: To assess the prevalence of extracardiac findings (ECF) during cardiovascular magnetic resonance (CMR) examinations and their downstream effect on clinical management. Materials and Methods: We retrospectively identified 500 consecutive patients. Trans-axial balanced steady-state free precession nongated images acquired from the upper thorax to the upper abdomen were evaluated independent
In this article I examine the current European refugee ‘crisis’ by challenging, from a theoretical perspective, the way in which the European Union (EU) has used the increased number of deaths in the Mediterranean as an opportunity to frame recent migration flows as an emergency which, by definition, can only be addressed through the adoption of exceptional measures. Throughout the article, I enga
The latest version of the Swiss standard for building acoustics (SIA181) introduced a new measurement method, based on a balanced- Arm hammer, for evaluating the decoupling performance of service equipment. This method was developed for reproducing in a standard manner the manipulation of service equipment in bathrooms and kitchens. In this study, we are investigating the relevance of such method
Rationale: Smoking is a primary risk factor for chronic bronchitis, emphysema, and chronic obstructive pulmonary disease, but since not all smokers develop disease, it has been suggested that some individuals may be more susceptible to exogenous factors, such as smoking, and that this susceptibility could be genetically determined. Objectives: The aim of the present study was to assess, in a popul
A unique set of gaseous mercury measurements in the upper troposphere and lower stratosphere (UT/LS) has been obtained during the monthly CARIBIC (www.caribic-atmospheric.com) flights since May 2005. The passenger Airbus 340-600 of Lufthansa covered routes to the Far East, North America, India, and the southern hemisphere. The accompanying measurements of CO, O3, NOy, H2O, aerosols, halocarbons, h
Background: The aim was to identify and characterize rare malignancies of the gallbladder, incidentally found at cholecystectomy, and describe the diagnostic work-up, treatment and outcome. Methods: Data from cholecystectomies during 2007–2014 registered in the Swedish Register for Gallstone Surgery (GallRiks) were analyzed for incidental cancer. For completion of the pathology report, data were l
The formation of the nuclear envelope and the subsequent compartmentalization of the genome is a defining feature of eukaryotes. Traditionally, the nuclear envelope was purely viewed as a physical barrier to preserve genetic material in eukaryotic cells. However, in the last few decades, it has been revealed to be a critical cellular component in controlling gene expression and has been implicated
Objective: To examine the relation of well-known factors of the metabolic syndrome (MetS) as well as related circulating factors, with risk of colorectal cancer. Methods: We performed a case control study of 306 colorectal cancer cases and 595 matched controls nested in the Northern Sweden Health and Disease Cohort. Levels of C-peptide, glycated haemoglobin (HbA1c), leptin and adiponectin were mea
Spectral induced polarization (SIP) measurements have been demonstrated to correlate with important parame-ters in hydrogeological and environmental investigations. Although SIP measurements were often collected in thefrequency domain (FDIP), recent developments have demonstrated the capabilities to solve for the frequency-de-pendence of the complex conductivity through measurements collected in t
Dispersal distance, measured as the number of territories between place of birth and place of first breeding, was analysed within and between sexes in juvenile marsh tits in relation to factors potentially caiusing variation in dispersal pattern. Dispersal distance of males was positively influenced by both population density and hatching date. In females, dispersal distance were positively relate
