Why Engage in Collective Action? The Conditional Effect of Social Support and Efficacy on Protest Participation

Why do people engage in collective actions, such as demonstrations? We suggest that intentions to engage in protest activities come from the perception that the action is an efficient way to affect policy but is also dependent upon the level of others’ engagement. Specifically, lower support should spur intentions to engage if the individual believes that the collective act is an efficient means t

Long-term effects of tungsten carbide (WC) nanoparticles in pelagic and benthic aquatic ecosystems

As the production and usage of nanomaterials are increasing so are the concerns related to the release of the material into nature. Tungsten carbide (WC) is widely used for its hard metal properties, although its use, in for instance tyre studs, may result in nano-sized particles ending up in nature. Here, we evaluate the potential long-term exposure effects of WC nanoparticles on a pelagic (Daphn

Adherence to diet recommendations and risk of abdominal aortic aneurysm in the Malmö Diet and Cancer Study

The research examining the association between quality of diet and abdominal aortic aneurysm (AAA) is scarce. The aim of the present study was to explore the association between diet quality and development of AAA for middle-aged individuals in the Malmö Diet and Cancer Study (MDCS), a prospective cohort study with baseline data collection carried out between 1991 and 1996. At baseline, the study

Platelet activation and aggregation by the opportunistic pathogen Cutibacterium (Propionibacterium) acnes

Cutibacterium (Propionibacterium) acnes, considered a part of the skin microbiota, is one of the most commonly isolated anaerobic bacteria from medical implants in contact with plasma. However, the precise interaction of C. acnes with blood cells and plasma proteins has not been fully elucidated. Herein, we have investigated the molecular interaction of C. acnes with platelets and plasma proteins.

The Impact of the Glomerular Filtration Rate on the Human Plasma Proteome

Purpose: The application of proteomics in chronic kidney disease (CKD) can potentially uncover biomarkers and pathways that are predictive of disease. Experimental design: Within this context, this study examines the relationship between the human plasma proteome and glomerular filtration rate (GFR) as measured by iohexol clearance in a cohort from Sweden (n = 389; GFR range: 8-100 mL min-1/1.73 m

Designing interactions by control of protein-ligand complex conformation : Tuning arginine-arene interaction geometry for enhanced electrostatic protein-ligand interactions

We investigated galectin-3 binding to 3-benzamido-2-O-sulfo-galactoside and -thiodigalactoside ligands using a combination of site-specific mutagenesis, X-ray crystallography, computational approaches, and binding thermodynamics measurements. The results reveal a conformational variability in a surface-exposed arginine (R144) side chain in response to different aromatic C3-substituents of bound ga

Molecular systematics of the subfamily Limenitidinae (Lepidoptera : Nymphalidae)

We studied the systematics of the subfamily Limenitidinae (Lepidoptera: Nymphalidae) using molecular methods to reconstruct a robust phylogenetic hypothesis. The molecular data matrix comprised 205 Limenitidinae species, four outgroups, and 11,327 aligned nucleotide sites using up to 18 genes per species of which seven genes (CycY, Exp1, Nex9, PolII, ProSup, PSb and UDPG6DH) have not previously be

Weibull triaxiality : A novel constraint assessment parameter for cleavage fracture in ductile to brittle transition region

The cleavage fracture probability of ferritic and ferritic/martensitic steels is generally computed using Beremin's model. In this work, a novel approach is developed for Beremin's model to be applicable to crack tip conditions under nonself similar stress field. The modification of Beremin's model corrects the inaccurate integration of local cleavage fracture probabilities of reference volume ele

A fracture mechanics model to study indentation cutting

Many cutting processes, such as chopping, slicing, and carving, consist in 2 different stages: an initial stage of indentation, in which the cutting tool is pushed into the material under the action of an external force, and a second stage, where the target material undergoes a progressive separation. This second stage is characterised by the formation of a fracture surface followed by the cut pro

The social structure of entrepreneurship as a scientific field

Entrepreneurship as a scientific field has grown significantly, irrespective of the measures used. In this article we raise the question: How can we understand the evolution and success of entrepreneurship as a scholarly field? In particular, we focus on the social structure of entrepreneurship scholars to explain (1) how they are becoming integrated into larger scholarly communities and (2) how t

Active retreat of a Late Weichselian marine-terminating glacier : An example from Melasveit, western Iceland

Large and complete glaciotectonic sequences formed by marine-terminating glaciers are rarely observed on land, hampering our understanding of the behaviour of such glaciers and the processes operating at their margins. During the Late Weichselian in western Iceland, an actively retreating marine-terminating glacier resulted in the large-scale deformation of a sequence of glaciomarine sediments. Du

Application of Py-GC/MS coupled with PARAFAC2 and PLS-DA to study fast pyrolysis of genetically engineered poplars

Field-grown genetically engineered and wild-type poplars were pyrolyzed in a micro-pyrolysis (Py-GC/MS) setup under fast pyrolysis conditions. Poplars (Populus tremula x P. alba) down-regulated for cinnamoyl-CoA reductase (CCR), which catalyzes the first step of the monolignol-specific branch of the phenylpropanoid biosynthetic pathway, were grown in field trials in France and harvested after a fu

Shock and stabilisation following long-term drought in tropical forest from 15 years of litterfall dynamics

Litterfall dynamics in tropical forests are a good indicator of overall tropical forest function, indicative of carbon invested in both photosynthesising tissues and reproductive organs such as flowers and fruits. These dynamics are sensitive to changes in climate, such as drought, but little is known about the long-term responses of tropical forest litterfall dynamics to extended drought stress.
