High-precision analyses of the isotopic composition of methane in ambient air can potentially be used to discriminate between different source categories. Due to the complexity of isotope ratio measurements, such analyses have generally been performed in the laboratory on air samples collected in the field. This poses a limitation on the temporal resolution at which the isotopic composition can be
Some complex plant-derived polysaccharides, such as modified citrus pectins and galactomannans, have been shown to have promising anti-inflammatory and anti-cancer effects. Most reports propose or claim that these effects are due to interaction of the polysaccharides with galectins because the polysaccharides contain galactose-containing side chains that might bind this class of lectin. However, t
This article explores the ethics of world heritage (WH) through a cosmopolitan lens. It proposes that cosmopolitanism provides fertile ground for the study of WH, in particular if combined with sensitivity to distinct indigenous ethical and political claims. Underpinning my article is the question of whether the politics of WH, despite its peaceful and universalist intensions, obscures local dispu
Arctic waders are well known for their impressive long-distance migrations between their high northerly breeding grounds and wintering areas in the Southern hemisphere. Performing such long migrations requires precise orientation mechanisms. We conducted orientation cage experiments with juvenile sharp-tailed sandpipers (Calidris acuminata) to investigate what cues they rely on when departing from
Collagen XVI is integrated tissue-dependently into distinct fibrillar aggregates, such as D-banded cartilage fibrils and fibrillin-1-containing microfibrils. In skin, the distribution of collagen XVI overlaps that of the collagen-binding integrins alpha 1 beta 1 and alpha 2 beta 1. Basal layer keratinocytes express integrin alpha 2 beta 1, whereas integrin alpha 1 beta 1 occurs in smooth muscle ce
Mapping of the spatial and temporal motion of particles inside an optical field is critical for understanding and further improvement of the 3D spatio-temporal control over their optical trapping dynamics. However, it is not trivial to capture the 3D motion, and most imaging systems only capture a 2D projection of the 3D motion, in which the information about the axial movement is not directly ava

In order to better address the feedbacks between climate and wetland methane (CH4) emissions, we tested several mechanistic improvements to the wetland CH4 emission model Peatland-VU with a longer Arctic data set than any other model: (1) inclusion of an improved hydrological module, (2) incorporation of a gross primary productivity (GPP) module, and (3) a more realistic soil-freezing scheme. A lo
Cyclin-dependent kinases (CDKs) that control cell cycle progression are regulated in many ways, including activating phosphorylation of a conserved threonine residue. This essential phosphorylation is carried out by the CDK-activating kinase (CAK). Here we examine the effects of replacing this threonine residue in human CDK2 by serine. We found that cyclin A bound equally well to wild-type CDK2 (C
We have investigated the inhibition of the recently identified family C13 cysteine peptidase, pig legumain, by human cystatin C. The cystatin was seen to inhibit enzyme activity by stoichiometric 1:1 binding in competition with substrate. The Ki value for the interaction was 0.20 nM, i.e. cystatin C had an affinity for legumain similar to that for the papain-like family C1 cysteine peptidase, cath

This study of plural suffixes in written plural contexts used by lebanese learners of second language French is based on previous works by Schlyter & Bartning (2004), Granfeldt et al. (2005) and Ågren (2008). The learning process of an L2 learner passes through stages that are clearly determined and systematic. In this study twenty lebanese learners of L2 French were asked to write a text base
It has long been debated whether second language learning activities that contain authentic materials are more effective than their constructed and more grammatical counterparts, and there is still no clear consensus on whether one is more efficient than the other. This research paper investigated the writing proficiency of four students learning French at Lund University in Sweden, where one stud
