Some of the characteristics of recent ultralow-emittance storage-ring designs and possibly future diffraction-limited storage rings are a compact lattice combined with small magnet apertures. Such requirements present a challenge for the design and performance of the vacuum system. The vacuum system should provide the required vacuum pressure for machine operation and be able to handle the heat lo
Background Stents are an alternative treatment to carotid endarterectomy for symptomatic carotid stenosis, but previous trials have not established equivalent safety and efficacy. We compared the safety of carotid artery stenting with that of carotid endarterectomy. Methods The International Carotid Stenting Study (ICSS) is a multicentre, international, randomised controlled trial with blinded adj
Ordered graphene films have been fabricated on Fe-treated SiC and diamond surfaces using the catalytic conversion of sp(3) to sp(2) carbon. In comparison with the bare SiC(0 0 0 1) surface, the graphitization temperature is reduced from over 1000 degrees C to 600 degrees C and for diamond (111), this new approach enables epitaxial graphene to be grown on this surface for the first time. For both s
To investigate the hypothesis that COMP can influence the morphology, stability and size of murine atherosclerotic lesions.
To assess the effect of comedication with conventional synthetic disease modifying antirheumatic drugs (csDMARDs) on retention to tumour necrosis factor inhibitor (TNFi) therapy in patients with ankylosing spondylitis (AS) and undifferentiated spondyloarthritis (uSpA).
Physical properties of importance in drying processes have been compiled for bark, including spruce, pine, and birch in Sweden. Water vapor sorption isotherms were determined for the bark of these trees. At 95% relative humidity and 25 degrees C, outer birch bark reached a moisture ratio (kg water/kg dry mass) of 5%, whereas inner birch bark, spruce bark, and pine bark reached moisture ratios of 2
The significance of mediatization in countryside settings is an under-researched topic in media studies. In this paper, based on qualitative fieldwork carried out in two rural areas in Sweden, we study how mediatization integrates the prospects of cosmopolitan social change. The current phase of the mediatization process, which imposes a more dynamic register of networked communication, nourishes
Agroforestry can contribute to the mitigation of climate change while delivering multiple benefits to sub-Saharan farmers who are exposed to climate variability, land degradation, water scarcity, high disease burden and persistent poverty. But adoption is slow. Based on a critical problem solving approach and grounded theory as a strategy, we study agroforestry and subsistence agriculture as integ
The O adsorption on Rh(100) has been studied using high resolution core level spectroscopy, low energy electron diffraction and scanning tunnelling microscopy. In addition to the well known (2 × 2), (2 × 2)-pg and c(8 × 2) structures at coverages of 0.25, 0.5 and 1.75 ML respectively, an intermediate (3 × 1) structure with a coverage of 2/3 ML is identified.
The crystal chemistry of the ternary Au-Cr-Zn alloy was studied by means of synthesis, single crystal X-ray diffraction, and electron structure calculations. While the compound CrZn∼17 represents the binary end-point of the homogeneity range, the inclusion of Au proves to be very site specific, and at the limiting composition Au10Cr4Zn89 the structure is completely ordered. The crystallographic si
Individual voice and speech characteristics are important for earwitness identification. A target-absent line-up with six foils was used to analyse the influence of voice and speech features on recognition. To create ecologically valid conditions for voice recognition, the present study used voices in conversation in the target event and for the foils. The participants were particularly successful
The regime of excellence - manifested in journal rankings and research assessments is coming to increasing prominence in the contemporary university. Critical scholars have responded to the encroaching ideology of excellence in various ways: while some seek to defend such measures of academic performance on the grounds that they provide accountability and transparency in place of elitism and privi
Tristan da Cunha is a volcanic island group situated in the central South Atlantic. The oldest of these islands, Nightingale Island, has an age of about 18Ma. In the interior of the island, there are several wetlands situated in topographic depressions. The ages of these basins have been unknown, and their genesis has been debated. Aiming towards the reconstruction of the geomorphological history
Having historically been abundant throughout Europe, the house sparrow (Passer domesticus) has in recent decades suffered severe population declines in many urban and rural areas. The decline in rural environments is believed to be caused by agricultural intensification, which has resulted in landscape simplification. We used giving-up densities (GUDs) of house sparrows feeding in artificial food
Species hybridization can lead to fitness costs, species collapse, and novel evolutionary trajectories in changing environments. Hybridization is predicted to be more common when environmental conditions change rapidly. Here, we test patterns of hybridization in three sympatric tree finch species (small tree finch Camarhynchus parvulus, medium tree finch Camarhynchus pauper, and large tree finch:
This article seeks to outline a conceptual landscape that can assist us to better grasp how urban communities torn and traumatised by violent conflicts remain divided in peace and resistant to liberal peacebuilding efforts. It suggests that peacebuilding needs to be urbanised to better address and mitigate tensions and ethnocratic spatial practices in divided cities. The urban is suggested as a pr
OBJECTIVES: To determine whether a long-term treatment with beta-blockers influences the inflammatory activity in carotid artery disease by reducing the carotid plaque levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), its enzymatic products lysophosphatidylcholine (lysoPCs), and of soluble urokinase plasminogen activator receptor (suPAR). MATERIALS AND METHODS: One hundred and thirty-fo
Background: We have developed a rapid method, based on lamellar body counts (LBC) on gastric aspirate, for identifying newborns who will develop respiratory distress syndrome with a need for surfactant supplementation. Objective: We set out to test whether it was possible to improve the outcome when used in a clinical trial. Methods: We randomly assigned 380 infants born at 24-29 weeks' gestation
