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
Barn- och ungdomspsykiatrin vänder sig till barn och ungdomar från 0 till 18 år och deras familjer. Forskning inom barn- och ungdomspsykiatri växer snabbt och det finns nu en stabil kunskapsbas för många av de psykiatriska tillstånden som debuterar under uppväxten.

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
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
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
The objective of this study was to examine the relationship between self-reported and professionally assessed functional limitations in community-dwelling very old individuals. In total, 306 single-living adults aged 81-90 years were included in this cross-sectional study. The main outcome measure was the presence and absence of self-reported and professionally assessed functional limitations. A s
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
With the popularization of the concept of the metaverse, non-immersive virtual reality (VR) has become a focus of tourism destination marketing. Drawing upon telepresence theory, this study identifies the antecedents and consequences of telepresence to help interpret tourist behavior in the context of non-immersive VR experience. Results revealed that mental imagery and vividness positively predic
Geophysical methods are increasingly being applied to geotechnical investigations, as they can identify material properties and material boundaries, as well as variations in space and time of relatively large volumes of soil. Another advantage is that many of these methods are non-intrusive. The combination of several methods and the verification of their results by sampling and correlating with g
Recent models have worked with the assumption that birds try to minimize either time, energy or predation risk during migration, or some combination of these. The few empirical studies available have suggested that time minimization may be the most common strategy. One way of distinguishing between strategies is to study the departure decisions of migrating birds. We supplied migrating European ro
