In this paper, we present a photoemission study of the interaction of Cu, Ag and Au with clean single-crystal Bi2CaSr2Cu2O8 superconductor surfaces. Both the valence-band and the Bi 5d, O 1s and Sr 3d core levels were monitored for all overlayers. Cu, Ag and Au were deposited as consecutively thicker layers starting with a third of a monolayer and progressing in steps up to a deposition in the ran
The ordered c(2×2) Na on Al(100) and (3 × 3) R30°K on Al(111) structures formed at either 100 K or at room temperature are studied by high-resolution core-level spectroscopy. For both systems equal alkali coverages are found at these two temperatures. The core-level spectra, however, show strong changes with temperature. This behavior leads to the surprising conclusion that annealing at room tempe
The surface core-level shift of the Pd(100) single-crystal surface has been measured from high-resolution Pd 3d core-level spectra. The surface atoms are found to have 0.44+or-0.03 eV lower binding energy than the bulk atoms. The result is compared with theoretical estimates.
The presentation of the United Nation’s (UN) Global Compact (hereinafter “GC” or “Compact”) in a book dedicated to monitoring mechanisms requires an urgent clarification: the GC itself is not a monitoring mechanism meant to deliver corporate accountability. Still, the Compact is an important hub in a broader network of initiatives dealing with responsible business practices and corporate accountab
Reproduction is a critical part of an animal's life history, but one which incurs significant costs to survival and future reproductive potential. These physiological consequences are likely to be influenced by context – for example, if an individual is subject to environmental stressors, physiological and behavioral changes associated with reproduction may be altered. Glucocorticoids, hormones pr
Non-β-hemolytic streptococci (NBHS) cause infective endocarditis (IE) and a short blood culture time to positivity (TTP) is associated with risk of IE in bacteremia with other pathogens. In this retrospective population-based cohort study, we investigate if TTP is associated to IE or mortality. Of 263 episodes with NBHS bacteremia, 28 represented IE and the median TTP did not differ significantly
SyfteMålsättningen med denna studie var dels att säkerställa att tågpersonalen inte utsätts för höga halter av partiklar i sitt arbete på X60B fordon som trafikerar Arlanda. Syftet var även att ta fram ett förhållande mellan partikelnivåerna i tunnelmiljö och ombord på pendeltågsfordon av typ X60B i förarhytterna för att avgöra ventilationsfiltrets kapacitet. Kunskapen om filtreringseffektiviteten
PM10 from the wear of disc brakes could contribute up to 50 % of the total non-exhaust emissions from road transport in EU. The wear originates from the contact surfaces of the friction material and the disc. One possible way of decreasing the PM10 emissions is to change the materials of the contact pair in terms of composition and coatings. Therefore the particle emissions of three novel friction
Recycling of brake pads is a tough but promising work considering the current end of lifecycle. This study assesses the environmental performance of brake pads made up of recycled friction materials in terms of energy use, CO2 footprint and airborne particle number. Energy use and CO2 footprint are calculated with the data from CES Edupack and airborne emission particle number is measured on a pin
Om vi vill rädda hotade insektsarter är det miljöer med traditionella ängsväxter som vi behöver mer av, inte fröblandningar av oklart ursprung från handeln. Det skriver flera debattörer.
We have combined high-energy surface X-ray diffraction (HESXRD) with 2D surface optical reflectance (2D-SOR) to perform in situ electrochemical measurements of a Au(111) electrode in 0.1 M HClO4 electrolyte. We show that electrochemically induced changes to Au(111) surface during cyclic voltammetry can be simultaneously observed with 2D-SOR and HESXRD. We discuss how small one atom high 1x1 island
Background: In many high-income countries, life expectancy (LE) has increased, with women outliving men. This gender gap in LE (GGLE) has been explained with biological factors, healthy behaviours, health status, and sociodemographic characteristics, but little attention has been paid to the role of public health policies that include/affect these factors. This study aimed to assess the contributi
Länsstyrelsen Skåne har släppt en ny rapport med de senaste vetenskapliga rönen om vilda bin i Skåne. Rapporten är en sammanställning om vilda bin och är ett led i Länsstyrelsens arbete med regeringsuppdraget att gynna vilda pollinatörer.Rapporten kan användas som underlag för att arbeta vidare med åtgärder för att gynna Skånes pollinatörer, något som är extra viktigt i Skåne eftersom runt 75 proc
Digital technology affords new means of controlling and managing. The platform economy relies on complex surveillance techniques to analyze, control, and manipulate on the basis of reviews, evaluations, and other volunteered data. This paper conceptualizes mechanisms of surveillance, with a focus on Airbnb. It sets out with a discussion of trust and reputation-building to then analyze the mechanis
Aims: The quality registry SWEDEHEART covers data across the patient pathway after an acute myocardial infarction (MI), from hospital care to secondary prevention. Although cardiac rehabilitation (CR) is strongly recommended after an MI, there is still heterogeneity regarding standards, uptake, and adherence rates. The aim of the SWEDEHEART-CR registry is to provide continuous information on secon
Syncope is a frequent event in the general population. Approximately 1%-2% of all emergency department admissions are due to syncope and at least one third of all people experience fainting in their life. Although consequences of cardiac syncope are generally feared, non-cardiac syncope is much more common and may be associated with severe injuries and quality of life impairment, particularly in o
