A computational fluid dynamics model of a channel (one liquid inlet, one liquid inlet and one two-phase outlet), applicable for PEFC gas channel water transport, is developed. A volume of fluid approach is used to study the two-phase flow behavior (interface-resolved) inside the gas channel, including the surface of GDL (gas diffusion layer), which is verified by experimental results from synchrot

BACKGROUND: Incidental durotomy (ID) is one of the most common intraoperative complications seen in spine surgery. Conflicting evidence has been presented regarding whether or not outcomes are affected by the presence of an ID. PURPOSE: To evaluate whether outcomes following degenerative spine surgery are affected by ID and the incidence of ID with different diagnoses and different surgical proced

Objective: To evaluate the test-retest reliability and variability of the Participation domain of the Stroke Impact Scale (SIS Participation) in persons with stroke as it is widely used to assess perceived participation in rehabilitation after stroke. Design: A test-retest design. Subjects: Forty-five persons (mean age 65 years) with mild to moderate disability at least 6 months post-stroke. Metho

Purpose: A hybrid planar-SPECT/CT method for tumor dosimetry in 177Lu-DOTATATE therapy, applicable to datasets consisting of multiple conjugate-view images and one SPECT/CT, is developed and evaluated. Methods: The imaging protocol includes conjugate-view imaging at 1, 24, 96, and 168 h post infusion (p.i.) and a SPECT/CT acquisition 24 h p.i. The dosimetry method uses the planar images to estimat

Under 2018 stormade det kring Svenska Akademien. I samband med detta trädde kungen plötsligt fram och menade sig ha befogenhet att ändra Akademiens stadgar. Detta innebär ett exempellöst utflöde av makt från kungen som inte har förekommit tidigare under 1974 års regeringsform och efter Torekovskompromissen. I denna text ska jag försöka presentera och diskutera de olika argument som har förts fram

From the point of view of semiotics, the essential contribution of John Deely consists in having made us all aware of the richness of the Scholastic heritage, and to have explained it to us latter-day semioticians. Even for those, who, like the present author, think that semiotics was alive and well between the dawn of the Latin Age, and the rediscovery of Scholastic realism by Peirce, the notions

Objective: Vascular endothelial growth factor D (VEGF-D) has important functions in lymphangiogenesis and angiogenesis. High plasma levels of VEGF-D have been associated with incidence of heart failure. The association of VEGF-D with atrial fibrillation (AF) and stroke is unclear and we hypothesised that VEGF-D could also be associated with incidence of AF and ischaemic stroke. Methods: VEGF-D was

BACKGROUND: As the patents of originator biologics are expiring, biosimilar versions are becoming available for the treatment of inflammatory bowel disease (IBD). However, published switch studies of the first infliximab biosimilar, CT-P13, have delivered ambiguous results that could be interpreted as showing a trend towards inferior effectiveness in Crohn's disease (CD) compared with ulcerative c

Evidence-based practice (EBP) has been launched, spread, and established in social work in Sweden in the last decade. Today, impact studies and ‘what works’ are the recommended approaches, and medical ways to understand and examine social problems thus are prioritised over the broad social science perspectives on which social work rests. This development has culminated in an institutionalised syst

Chromosomal aberrations (CAs) in human peripheral blood lymphocytes (PBL) measured with the conventional cytogenetic assay have been used for human biomonitoring of genotoxic exposure for decades. CA frequency in peripheral blood is a marker of cancer susceptibility. Previous studies have shown associations between genetic variants in metabolic pathway, DNA repair and major mitotic checkpoint gene

Explaining macroevolution from microevolution is a key issue in contemporary evolutionary theory. A recurrent macroevolutionary pattern is that some niche-related traits consistently evolve slower than others, so called niche conservatism. Despite a growing amount of data, the underlying evolutionary processes are not fully understood. I here analyse adaptive radiations in an individual-based eco-

Hip fractures in elderly carry a high mortality. Our objective was to test the hypothesis that plasma lactate concentration at hospital admission can be used to identify patients with a high risk for poor outcome. Hip fracture patients admitted to a university hospital in Sweden from January 2011 to August 2014 in whom a venous lactate was obtained at admission were included in this prospective ob
