Selfsimilar solutions for stress driven material dissolution : Advanced Fracture Mechanics for Life and Safety Assessments

During corrosive dissolution of metal ions from a body surface, an oxide compound isproduced. This compound forms a protective film that reduces the dissolution rate. When afraction of a millimetre depth is dissolved the dissolution rate become insignificant. However,repeated loading will damage the film with continued dissolution as a result. In connectionwith this a threshold strain is assumed tDuring corrosive dissolution of metal ions from a body surface, an oxide compound isproduced.

Implementation of the Swedish Guideline for Prevention of Mental ill-health at the Workplace : study protocol of a cluster randomized controlled trial, using multifaceted implementation strategies in schools

BACKGROUND: Given today's high prevalence of common mental disorders and related sick leave among teachers, an urgent need exists for a more systematic approach to the management of social and organizational risk factors within schools. In 2015, we launched the first Swedish occupational health guideline to support a structured prevention of these risks at the workplace. The existence of guideline

Genetic predisposition for multiple myeloma

Multiple myeloma (MM) is the second most common blood malignancy. Epidemiological family studies going back to the 1920s have provided evidence for familial aggregation, suggesting a subset of cases have an inherited genetic background. Recently, studies aimed at explaining this phenomenon have begun to provide direct evidence for genetic predisposition to MM. Genome-wide association studies have

Incidence, Predictors, and Success of Ventricular Tachycardia Catheter Ablation in Arrhythmogenic Right Ventricular Cardiomyopathy (from the Nordic ARVC Registry)

Catheter ablation may reduce ventricular tachycardia (VT) burden in arrhythmogenic right ventricular cardiomyopathy (ARVC) patients. However, little is known about factors predicting need for ablation. Therefore, we sought to investigate predictors and use of VT ablation and to evaluate the postprocedural outcome in ARVC patients. We studied 435 patients from the Nordic ARVC registry including 220

Resolving the shortest path problem using the haversine algorithm

Route search requires a useful and accurate algorithm to calculate the distance between two objects, especially on a round surface such as the earth. This algorithm provides a considerable circle distance between two locations on a non-flat surface. The distance of the two objects is determined based on longitude and latitude. Haversine is an algorithm that can determine the distance between two o

GeoBIM Benchmark 2019 : Intermediate results

An investigation into the implementation state of open standards in software is currently ongoing through the ISPRS/EuroSDR 'GeoBIM benchmark 2019' initiative, which kicked off earlier this year. The benchmark activity provides a way of assessing and comparing the functionality of different software packages in GIS and BIM in terms of their ability to handle standardised data (IFC and CityGML) and

EuRoSDR GeoBIM project a study in Europe on how to use the potentials of BIM and GEO data in practice

In both the Geo and BIM domains, it is widely acknowledged that the integration of geo-data and BIM-data is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration - broadly termed as GeoBIM - has a range of potential uses from district study to road safety. However, from the data perspective, this integration raises the qu

Editorial Annals of Regional Science

There is no tradition in Annals of Regional Science that the editors write editorials. However, as of 2020, the editors will each year write an editorial in which we report as well as refect on recent developments of the journal. We hope that this will be of interest for our readers. This editorial is the frst one and marks the start of the strategy to write a yearly editorial. We, i.e., Martin An

Outpatient volumes and medical staffing resources as predictors for continuity of follow-up care during transfer of adolescents with congenital heart disease

Background: Providing continuous follow-up care to patients with congenital heart disease (CHD) remains a challenge in many settings. Previous studies highlight that patients with CHD experience discontinuation of follow-up care, but mainly describe a single-centre perspective, neglecting inter-institutional variations. Hospital-related factors above and beyond patient-related factors are believed

Identification of elastic/visco-plastic material constants under impact loading

A numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading. The identification is based on an inverse analysis using the Kalman filter technique and the finite element method. The input data to the inverse analysis are the time histories of the strains on specimens. The measurement errors can be treated reasonably by thA numerical simulation is performed to identify the material parameters of an elastic/visco-plastic material under tensile impact loading.

High-performance solid oxide fuel cells with fiber-based cathodes for low-temperature operation

Low-temperature operation of solid oxide fuel cells (SOFCs) results in deterioration in electrochemical performance due to sluggish oxygen reduction reaction (ORR) at the cathode. To enhance the reaction pathway for ORR, La0.8Sr0.2MnO3 (LSM) nanofibers were fabricated by electrospinning and used for low-temperature solid oxide fuel cells operated at 600–700 °C. The morphological and structural cha

Investigation of dilution effect on CH4/air premixed turbulent flame using OH and CH2O planar laser-induced fluorescence

Diluting the combustion mixtures is one of the advanced approaches to reduce the NOx emission of methane/air premixed turbulent flame, especially with high diluents to create a distributed reaction zone and mild combustion, which can lower the temperature of reaction zone and reduce the formation of NOx. The effect of N2/CO2 dilution on the combustion characteristics of methane/air premixed turbul

Foetal and neonatal alloimmune thrombocytopenia – The role of the HLA-DRB3*01:01 allele for HPA-1a-immunisation and foetal/neonatal outcome

Foetal and neonatal alloimmune thrombocytopenia (FNAIT) is the platelet counterpart of haemolytic disease of the foetus and newborn. Among Caucasians, around 80 % of FNAIT cases and some of the most severe cases, are caused by alloantibodies against the human platelet antigen 1a (HPA-1a). For around 3 decades it has been known that almost all HPA-1a-immunised women are HLA-DRB3*01:01 positive. The

Relationship between degree of heparin anticoagulation and clinical outcome in patients receiving potent P2Y12-inhibitors with no planned glycoprotein IIb/IIIa inhibitor during percutaneous coronary intervention in acute myocardial infarction : a VALIDATE-SWEDEHEART substudy

AIMS: Heparin is the preferred choice of anticoagulant in percutaneous coronary intervention (PCI) for acute myocardial infarction (MI). An established dosage of heparin has not yet been determined, but treatment may be optimized through monitoring of activated clotting time (ACT). The aim of this study was to determine the relationship between heparin dose or ACT with a composite outcome of death

Near-visible-light-driven noble metal-free of reduced graphene oxide nanosheets over CeO2 nanowires for hydrogen production

This study is the first to use a newly-developed material via hydrothermal method, cerium oxide nanowires doped with reduced graphene oxide (CNW-RGO) for reductive H2 production. The detailed characteristics of the CNW-RGO materials were investigated to explore the capabilities of reductive production. The mean diameter of the CNWs was uniform at 22 nm. Owing to RGO-doping, the energy gap between

Applications and Approaches for Three-Dimensional Precision-Cut Lung Slices. Disease Modeling and Drug Discovery

Chronic lung diseases (CLDs), such as chronic obstructive pulmonary disease, interstitial lung disease, and lung cancer, are among the leading causes of morbidity globally and impose major health and financial burdens on patients and society. Effective treatments are scarce, and relevant human model systems to effectively study CLD pathomechanisms and thus discover and validate potential new targe
