IntroductionMilitary tasks place considerable physiological demands on the soldier. It is therefore important to know the energy expenditure of soldiers while solving tasks in different environments. The purpose of this study was to describe the cardiorespiratory demands of certain movements and activities on ground combat soldiers during military field operations using body sensors and simulated

The relationship between gender and mortality in nineteenth-century Europe has been highly debated. In particular, historians disagree about the manner and degree to which gender discrimination affected the mortality risk of the female population. This article contributes by examining the evidence of gendered mortality differences among children and adolescents in nineteenth-century Denmark. It ma

The data generated in our digital society can be harnessed to generate policy-relevant indicators on waste prevention and reuse, and be used to fill in the gaps left by official data and statistics. This project elaborates where the greatest potentials lie for improving the monitoring of waste prevention and reuse, and presents a roadmap for improving the monitoring of waste prevention in the Nord

High latitude organic soils form a significant carbon storage and deposition of these soils is largely driven by climate. Svalbard, Norway, has experienced millennial-scale climate variations and in general organic soil processes have benefitted from warm and humid climate phases while cool late Holocene has been unfavourable. In addition to direct effect of cool climate, the advancing glaciers ha

Recent studies suggest that metabolic changes and oxygen deficiency in the central nervous system play an important role in the pathophysiology of multiple sclerosis (MS). In our present study, we investigated the changes in oxygenation and analyzed the vascular perfusion of the spinal cord in a rodent model of MS. We performed multispectral optoacoustic tomography of the lumbar spinal cord before

While lithium-sulfur batteries theoretically have both high gravimetric specific energy and volumetric energy density, only its specific energy has been experimentally demonstrated to surpass that of the state-of-the-art lithium-ion systems at cell level. One major reason for the unrealized energy density is the low capacity density of the highly porous sulfur/carbon composite as the positive elec

Introduction: Air pollution is associated with increased risk of cardiovascular disease, possibly through chronic systemic inflammation that promotes the progression of atherosclerosis and the risk of cardiovascular events. This study aimed to investigate the associations between air pollution and established biomarkers of inflammation and cardiovascular disease. Methods: The Cardiovascular Subcoh

Second language (L2) learners experience challenges when word meanings differ across L1 and L2, and often display crosslinguistic influence in speech production. In contrast, studies of online comprehension show more mixed results. Therefore, this study explored how L2 learners process fine-grained L2 verb semantics in the domain of caused motion (placement), and specifically the impact of having

Aim: To describe survival and neonatal morbidities in infants born before 24 weeks of gestation during a 12-year period. Methods: Data were retrieved from national registries and validated in medical files of infants born before 24 weeks of gestation 2007–2018 in Sweden. Temporal changes were evaluated. Results: In 2007–2018, 282 live births were recorded at 22 weeks and 460 at 23 weeks of gestati

Components of the extracellular matrix (ECM), when exposed to body fluids may promote local complement activation and inflammation. Pathologic complement activation at the glomerular basement membrane and at the Bruch’s membrane is implicated in renal and eye diseases, respectively. Binding of soluble complement inhibitors to the ECM, including factor H (FH), is important to prevent excessive comp

This paper investigates how right-wing populist voting following the 2015 refugee wave was affected by regional characteristics, using data from a quasi-natural experiment in Sweden. The results suggest that voting outcomes are heavily dependent on pre-influx municipal characteristics. In localities with strong anti-immigration sentiments during the 1990s refugee wave, as well as in areas with hig

This paper reports on a one-to-one relation between articulation and acoustics. It explains how segment boundaries are a result of rapid movements of the articulators. In the acceleration profile, this is identified as peak acceleration, which can be measured. A previous study found that rapid movements of an active articulator - peak acceleration - correlate with the acoustic segment boundary in

During the last two decades, molecular methods to study mitochondrial DNA sequence variation have become an important part in the studies of avian haemosporidians. Up until recently, these methods have primarily been used for identification of the parasites and for tentative phylogenetic reconstructions, allowing researchers not trained in traditional parasitology to compare data across the globe.During the last two decades, molecular methods to study mitochondrial DNA sequence variation have become an important part in the studies of avian haemosporidians.

BACKGROUND: Avian beta-defensins (AvBDs) represent a group of innate immune genes with broad antimicrobial activity. Within the chicken genome, previous work identified 14 AvBDs in a cluster on chromosome three. The release of a second bird genome, the zebra finch, allows us to study the comparative evolutionary history of these gene clusters between from two species that shared a common ancestor

Allelic variation in immune genes might result from, and contribute to, host-pathogen evolution. Functional allelic variation in the innate immune system has received little attention. Here, we investigate whether naturally occurring allelic variation within the avian innate immune system (β-defensins) is associated with variation in antimicrobial activity. We tested differences in in vitro antimi

During a parasite survey, we collected data on the presence and distribution of feather mites, intestinal parasites, and blood parasites of small ground finches (Geospiza fuliginosa) from 4 islands in the Galapagos. We recorded 4 species of feather mites, with the most common species, Trouessartia geospiza, present on the majority (77% 308/400) of individuals. Birds with high loads of T. geospiza
