Adsorption of glycine on Pt{111} under UHV conditions and in different aqueous environments was studied by XPS (UHV and ambient pressure) and NEXAFS. Under UHV conditions, glycine adsorbs in its neutral molecular state up to about 0.15 ML Further deposition leads to the formation of an additional zwitterionic species, which is in direct contact with the substrate surface, followed by the growth of
Planning for future needs has traditionally been considered to be restricted to human cognition. Although recent studies on great ape and corvid cognition challenge this belief, the phylogenesis of human planning remains largely unknown. The complex skill for future planning has not yet been satisfactorily established in any other extant primate species than our own. In humans, planning for future
Freshwater blooms of cyanobacteria (blue-green algae) in source waters are generally composed of several different strains with the capability to produce a variety of toxins. The major exposure routes for humans are direct contact with recreational waters and ingestion of drinking water not efficiently treated. The ultra high pressure liquid chromatography tandem mass spectrometry based analytical
Haem (protohaem IX) analogues are toxic compounds and have been considered for use as antibacterial agents, but the primary mechanism behind their toxicity has not been demonstrated. Using the haem protein catalase in the Gram-positive bacterium Enterococcus faecalis as an experimental system, we show that a variety of haem analogues can be taken up by bacterial cells and incorporated into haem-de
The presence of genes encoding organellar proteins in different cellular compartments necessitates a tight coordination of expression by the different genomes of the eukaryotic cell. This coordination of gene expression is achieved by organelle-to-nucleus communication. Stress-induced perturbations of the tetrapyrrole pathway trigger large changes in nuclear gene expression. In order to investigat
Pyrimidine bases are the central precursors for RNA and DNA, and their intracellular pools are determined by de novo, salvage and catabolic pathways. In eukaryotes, degradation of uracil has been believed to proceed only via the reduction to dihydrouracil. Using a yeast model, Saccharomyces kluyveri, we show that during degradation, uracil is not reduced to dihydrouracil. Six loci, named URC1-6 (f
ABSTRACT Learning and other forms of phenotypic plasticity have been suggested to enhance population divergence. Mate preferences can develop by learning, and species recognition might not be entirely genetic. We present data on female mate preferences of the banded demoiselle (Calopteryx splendens) that suggest a role for learning in population divergence and species recognition. Populations of t
This paper proposes a fast method for detection of indecent video content using repetitive motion analysis. Unlike skin detection, motion will provide invariant features irrespective of race and color. The video material to be evaluated is divided into short fixed-length sections. By filtering different combinations of B-frame motion vectors using adjacency in time and space, one dominant motion v
Understanding species’ historical ranges can provide important information for conservation planning in the face of environmental change. Cromsigt et al. (this issue) comment on our recent European bison (Bison bonasus) range reconstruction, suggesting that bison were already 8000 years ago a refugee species (i.e. restricted to marginal habitat due to past human pressure) and that species distribu
This paper presents an implementation of a federated resource allocation system (Puhuri), which offers a full set of functions from the application phase for computing infrastructure resources to consumption reporting. The implementation is based on the Puhuri project of Nordic e-Infrastructure Collaboration (NeIC) [1]. Shared research infrastructures, particularly high-performance computers, nece
Background and Purpose: Absence from work due to illness is common in many western countries and has many negative consequences for both the individual and society. Since 2020 Swedish healthcare regions are required to provide resources to coordinate the rehabilitation process, a complex system involving medical as well as work-related parties, where both the physician and the rehabilitation coord
The notion of blended finance has increasingly gained traction within development policy as a way to fill a series of “financing gaps” related to the Sustainable Development Goals. Recently, blended finance has received increased attention as a way to create biodiversity markets and attract private capital. Building on qualitative research on efforts to create markets for private investments in ma
Aim: To assess the prognostic value of auditory event-related potentials (AERPs) registered at term equivalent age in very preterm infants. Methods: Infants (26.5 ± 2.0 gestational weeks (GWs), n = 41 of 64 recruited) were enrolled prenatally between January 2005 and May 2007 at Skåne University Hospital, Lund, Sweden. AERP and mismatch responses to changes in duration or frequency in pure tones w
More recently, the number of elderly immigrants has increased. This means that Sweden is faced with new challenges. The purpose of this study was to illustrate how the elder immigrants general situation in Helsingborg looks like, as well as how social workers work to integrate this target group. Furthermore, I wished to have an answer on whether social workers feel that there is a continuing need
Men's violence against women is an issue that exists all over the world. There are several scientists and organisations that work with this issue in one way or another. In Sweden an organisation called ROKS, and a scientist called Eva Lundgren, has been in the limelight for medias attention several times. The impression has been given that Eva Lundgren is a very controversial scientist and tha
