We have characterized a putative Ca(2+)-ATPase from the pathogenic bacterium Listeria monocytogenes with the locus tag lmo0841. The purified and detergent-solubilized protein, which we have named Listeria monocytogenes Ca(2+)-ATPase 1 (LMCA1), performs a Ca(2+)-dependent ATP hydrolysis and actively transports Ca(2+) after reconstitution in dioleoylphosphatidyl-choline vesicles. Despite a high sequ

Permafrost degradation has the potential to change the Arctic tundra landscape. We observed rapid local thawing of ice-rich permafrost resulting in thaw pond formation, which was triggered by removal of the shrub cover in a field experiment. This study aimed to examine the rate of permafrost thaw and the initial vegetation succession after the permafrost collapse. Methods In the experiment, we mea

Purpose:The article makes an empirical and conceptual contribution to understanding the temporalities of information literacies. The paper aims to identify different ways in which anticipation of certain outcomes shapes strategies and tactics for engagement with algorithmic information intermediaries. The paper suggeststhat, given the dominance of predictive algorithms in society, information lite

The present study is a part-study of the EVEDMUS (evaluation of teacher education in music) project aiming to examine the music teacher education programmes across Europe and Latin America. The overarching objective of the EVEDMUS project is to learn about the different conditions and causes in which the musical and educational knowledge is being constructed and identify factors in the programmes

Popular science The eddy-covariance (EC) method is one of the most important methods to measure gas and energy fluxes between biosphere and atmosphere at ecosystem level. This method was applied above the floor of a boreal forest in Norunda, central Sweden, at 1.5 m height. The objective was to measure the energy and carbon dioxide (CO2) fluxes from the soil and the understory vegetation to the at

The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure f

Three phases of archaeological investigations have been conducted in the area of the City Museum of Novi Sad at the Petrovaradin Fortress. In this study, we summarize the results of geoarchaeological research carried out during the third phase of excavations inside the museum building. The investigated area covered 27 m2. The approximately 0.60 m thick loessic sequence offers a unique opportunity

The platelet-derived growth factor (PDGF) alpha and beta receptors undergo dimerization as a consequence of ligand binding. Depending on the PDGF isoform (PDGF-AA, -AB or -BB), homodimers or heterodimers of receptors are formed. In this study, we have used transfected porcine aortic endothelial cells, coexpressing cDNAs for the alpha receptor and the beta receptor at comparable levels, to investig

Late glacial skeletal remains from mainly reindeer and wild horse, but also other species such as mountain hare, arctic fox and elk have been collected from kettle holes in Hässleberga, Scania. Bones from reindeer and wild horse have been radiocarbon dated to Allerød and Younger Dryas. Analysis of bone modifications has revealed several different actors and factors behind the accumulation of the s
