A polymer electrolyte fuel cell (PEFC) produces electrical energy according to the electrochemical reactions carried out inside the cell. During the energy conversion, water molecules are also produced at the cathode side, which affects the gas diffusion layer (GDL) diffusion parameters. The generated water-drops from the reaction may give partial or total blockage of the reactant gases and also m

Colorectal cancer (CRC) is the third most common cancer worldwide. Increasing evidence suggests that CRC should be considered a heterogeneous disease, with multiple differences between proximal and distal tumours. The immune system may, depending on the context, promote or inhibit tumour growth, and different immune cell subsets have been found to be associated with impaired or improved prognosis

OBJECTIVES: Infections with extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae (EPE) are a major healthcare concern. Our goal was to investigate whether a probiotic mixture could be used for eradication therapy in patients with prolonged intestinal EPE carriage.METHODS: We performed a randomized, placebo-controlled single blinded clinical superiority trial in the south of Sweden

There is a wide-spread concern that technical change may spur social conflicts, especially if workers are replaced with machines. To empirically analyze whether job destruction drives protests, we study a historical example of a revolutionary new technology: the adoption of electricity. Focusing on the gradual roll-out of the Swedish electricity grid between 1900 and 1920 enables us to analyze 2,4

The labour market region of Olofström-Karlshamn experienced a period of exceptional economic decline between 2007 and 2010, prompted primarily by the job loss that resulted from restructuring within Volvo. In December 2008 around 1000 jobs disappeared overnight, throwing the municipality of 15000 people into crisis, and further rippling through the region. This is a story of a peripheral region de

The influence of military members’ malevolent personality traits on their ethical attitudes and behaviors has been the subject of research for decades. We investigated the relationship between malevolent individual difference factors (Machiavellianism, narcissism, psychopathy, the dominance facet of social dominance orientation, and right-wing authoritarianism) and aspects of military ethics befor

Utifrån berättelsen om slaget på Kävlinge bro som finns i Ry klosters årbok görs en expose av tänkbara scenario utifrån arkeologi, numismatik och historievetenskap.

Background: Early-onset pancreatic cancer (< 50 years, EOPC) is uncommon and limited data exist on clinical presentation and long-term survival. The aim of this study was to compare outcomes between patients with EOPC and those with later-onset pancreatic cancer (≥ 50 years, LOPC) using a large population-based cohort. Methods: The Surveillance, Epidemiology, and End Results (SEER) database was qu

Many viruses previously have been shown to have pressurized genomes inside their viral protein shell, termed the capsid. This pressure results from the tight confinement of negatively charged viral nucleic acids inside the capsid. However, the relevance of capsid pressure to viral infection has not been demonstrated. In this work, we show that the internal DNA pressure of tens of atmospheres insid

This Letter describes the observation of the light-by-light scattering process, γγ→γγ, in Pb+Pb collisions at sqrt[s_{NN}]=5.02 TeV. The analysis is conducted using a data sample corresponding to an integrated luminosity of 1.73 nb^{-1}, collected in November 2018 by the ATLAS experiment at the LHC. Light-by-light scattering candidates are selected in events with two photons produced exclusively,

Diurnal raptors (birds of the orders Accipitriformes and Falconiformes), renowned for their extraordinarily sharp eyesight, have fascinated humans for centuries. The high visual acuity in some raptor species is possible due to their large eyes, both in relative and absolute terms, and a high density of cone photoreceptors. Some large raptors, such as wedge-tailed eagles and the Old World vultures,

Increased levels of the urinary albumin-to-creatinine ratio (UACR) are associated with higher risk of kidney disease progression and cardiovascular events, but underlying mechanisms are incompletely understood. Here, we conduct trans-ethnic (n = 564,257) and European-ancestry specific meta-analyses of genome-wide association studies of UACR, including ancestry- and diabetes-specific analyses, and

Two Lactobacillus strains have proven anti-inflammatory properties by reducing pro-inflammatory responses to antigens. This randomized double-blind placebo-controlled trial tested the hypothesis that L. plantarum HEAL9 and L. paracasei 8700:2 suppress ongoing celiac disease autoimmunity in genetically at risk children on a gluten-containing diet in a longitudinally screening study for celiac disea

Objective: Survival in cervical cancer has improved little over the last decades. We aimed to elucidate primary treatment patterns and survival. Methods: Population-based study of patients included in the Swedish Quality Registry for Gynecologic Cancer diagnosed 2011–2015. Main outcome was 5-year relative survival (RS). Age-standardised RS (AS-RS) was estimated for the total cohort and for the poo

The production of charm jets in proton-proton collisions at a center-of-mass energy of s=7 TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total integrated luminosity of 6.23 nb−1, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D0 meson among their constituents. The D0 m

Klimatkrisen framstår mer och mer som det största hot människan någonsin ställts inför. Även om det politiska svaret kan beskrivas som avvaktande, pågår arbete för att på olika sätt minska klimatförändringarnas effekter, och hantera de risker vi kommer att ställas inför. Världssamfundet är enigt. Den globala medeltemperaturen bör inte öka med mer än 2 grader, och helst inte mer än 1,5 grader, jämfClimate change is a growing threat to mankind. The message from the scientific community is clear: we need to act fast and profoundly. The political response has, however, been slow. The likelihood that we will be able to meet our political climate goals only by reducing emissions is slim. Meanwhile is the interest around ways to capture carbon dioxide that has already been emitted on the rise. In

There is a growing appreciation of the need and urgency to study and document mobility and energetics among extant hunter-gatherers. An increasing number of studies investigate the spatial and biophysical properties of hunter-gatherer movement, in order to gain a deeper understanding of such things as human energy expenditure and efficiency in human foraging behavior. So far, however, this researc
