The interaction of antikaons (K) with nucleons and nuclei in the low-energy regime represents a very active research field in hadron physics. A unique and rather direct experimental access to the antikaon-nucleon scattering lengths is provided by precision X-ray spectroscopy of transitions in low-lying states in the lightest kaonic atoms (i.e. kaonic hydrogen and deuterium). In the SIDDHARTA exper

The implementation of Sustainable Urban Drainage Systems (SUDS) in the northern hemisphere is confronted with the problem of decreased infiltration during winter because of frozen soils. The goal of this research was to assess the winter infiltration capacity of a grass swale and natural vegetation cover during frequent freeze-thaw cycles. Infiltration was measured with eight single-ring infiltrom

The atrioventricular (AV) node plays a central role during atrial fibrillation (AF). We have recently proposed a statistical AV node model defined by parameters characterizing the arrival rate of atrial impulses, the probability of an impulse choosing either one of the dual AV nodal pathways, the refractory periods of the pathways, and the prolongation of refractory periods. All model parameters a

The abstract with its heading should not be more than 75 mm long. This is equivalent to 18 lines of text. Leave 1 line space at the bottom of the abstract before continuing with the next heading. The autonomic nervous system modulates atrial electrophysiology in atrial fibrillation (AF). The purpose of this study was (1) to non-invasively characterize the effects of exercise on atrial fibrillatory

Sweden and other developed countries are putting deliberate efforts into eHealth and digitalization of home care nursing. eHealth services have big potential in this area because they can provide mobile access to healthcare information. This study explores the eHealth services that home care nursing providers in Sweden currently use, plan to use, and have discarded. It also investigates their eHea

During spring and autumn a special thermohydrodynamic phenomenon, called a thermal bar, can be observed in dimictic lakes. [A dimictic lake is a lake where a complete turnover of the water occurs twice a year (in spring and autumn).] The thermal bar is a zone of mixing that separates waters with temperatures above and below 4° C. Its practical importance is due to the possibility that it might iso

Background: Cluster analyses have proposed different diabetes phenotypes using age, BMI, glycaemia, homoeostasis model estimates, and islet autoantibodies. We tested whether comprehensive phenotyping validates and further characterises these clusters at diagnosis and whether relevant diabetes-related complications differ among these clusters, during 5-years of follow-up. Methods: Patients with new

This presentation will give an overview of a peer learning model called Supplemental Instruction - Peer Assisted Study Scheme (SI-PASS). SI-PASS was invented at the University of Missouri in Kansas City, USA in the early1970s and was then directed to Universities and for the university students. In this presentation, the focus and discussion will be on how SI-PASS can be implemented in secondary s

The relationship between carbon (C) inputs and nitrogen (N) fertilisation is a key element of soil organic matter (SOM) dynamics, which remains poorly resolved. In temperate climates, it is critical to investigate the interactive effect of C and N inputs on SOM stabilisation under low or high substrate availability. We measured SOM content and in situ soil respiration in a long-term field experime

The effects of altered N-methyl-D-aspartate (NMDA) receptor subunit composition on seizure development in kindling epilepsy were assessed in transgenic mice expressing high neuronal levels of NR2D under control of the calcium/calmodulin kinase II alpha subunit (αCaMKII) promoter. The NR2D subunit is normally present at very low levels in the mature forebrain. Transgenic mice showed a marked reduct

Dissolved organic carbon (DOC) plays a key role in linking terrestrial and aquatic carbon cycles. Most of the work on soil and water DOC has been conducted in temperate watersheds. There is still a gap in knowledge on DOC dynamics within the tropics. This study assesses water extractable organic carbon (WEOC) in topsoils and describes the relationship between WEOC and land use/land cover (LULC), s

Optimized biogenic carbon fluxes for Europe wereestimated from high-resolution regional-scale inversions, uti-lizing atmospheric CO2measurements at 16 stations for theyear 2007. Additional sensitivity tests with different data-driven error structures were performed. As the atmosphericnetwork is rather sparse and consequently contains large spa-tial gaps, we use a priori biospheric fluxes to furthe

Nature-based tourism in the fragile Arctic environments is emerging as a major environmental concern, mainly due to extreme seasonality in these locations, the lack of suitable infrastructures and planning, and its interference with fragile ecosystems. In Iceland tourism has increased exponentially during the past decades, causing more environmental impacts on the country's natural recourses. Hiki

Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971–2017) demonstrate fundamental changes among nine key elements of the Arctic system. We find that, coherent with increasing air temperature, there is an intensification of the hydrological cycle, evident from increases in humidity, precipitation, river discharge, glacier equilibrium line altitude and
