European rivers experience increased loading of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, little is known about how increased TOC is linked to changes in the bioreactivity of organic matter in these rivers on a continental scale. We compiled paired measurements of TOC and biological oxygen demand in 5‐day 20
The multiplicity dependence of electron production from heavy-flavour hadron decays as a function of transverse momentum was measured in p-Pb collisions at sNN = 5.02 TeV using the ALICE detector at the LHC. The measurement was performed in the centre-of-mass rapidity interval −1.07 < ycms< 0.14 and transverse momentum interval 2 < pT< 16 GeV/c. The multiplicity dependence of the production of ele
A search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented. The analysis is based on 139 fb- 1 of proton–proton collisions recorded by the ATLAS detector at the Large Hadron Collider at s=13 TeV. Three R-parity-conserving scenarios where the lightest neutralino is the lightest supersymmetric particle are considered: the pro
PURPOSE: The aim of this study was to investigate how the blood perfusion in human upper eyelid skin flaps is affected by the length of the flap and the degree of stretching and rotation of the flap.METHODS: Twenty-nine upper eyelids were dissected as part of a blepharoplastic procedure in patients. The 1-cm wide proximal end of the flap remains attached, to mimic a random pattern skin flap (herea
MAX IV is a fourth-generation, or diffraction-limited, synchrotron light source with a number of state-of-the-art beamlines. The performance of a beamline is, to a high degree, set by the energy resolution it can achieve, which in turn is governed to a large extent by the monochromator. During the design phase of a monochromator, the mechanical requirements must be fully understood and met with ma
With the introduction of the multi-bend achromats in the new fourth-generation storage rings the emittance has decreased by an order of magnitude resulting in increased brightness. However, the higher brightness comes with smaller beam sizes and narrower radiation cones. As a consequence, the requirements on mechanical stability regarding the beamline components increases. Here an innovative five-
En infektionssjukdom som covid-19 hotar både den mänskliga säkerheten och den nationella säkerheten. En politisk instabilitet till följd av en dålig ekonomi, minskat förtroende för samhällsinstitutioner, generell demoralisering samt rädsla, kan också ge konsekvenser som direkt hotar Sveriges säkerhet, skriver Ardavan Khoshnood, läkare och kriminolog.An infectious disease such as COVID-19 threatens both human security and national security. Political instability as a result of poor economy, diminished confidence in institutions, general demoralization and fear can also have consequences that directly threaten Sweden’s security, writes Ardavan Khoshnood, physician and criminologist.
Arterial stiffening is a hallmark of early vascular aging (EVA) syndrome and an independent predictor of cardiovascular morbidity and mortality. In this case-control study we sought to identify plasma metabolites associated with EVA syndrome in the setting of hypertension. An untargeted metabolomic approach was used to identify plasma metabolites in an age-, BMI-, and sex-matched groups of EVA (n
Raoul Wallenberg, the courageous Swedish financier and trade executive turned diplomat who saved thousands of Jews in Hungary in 1944, was arrested in January 1945 by the Soviet military counterintelligence, incarcerated in the Lubianka prison in Moscow, and later executed for reasons that remain obscure to this day. Drawing on recently declassified Soviet encrypted cables and a wide array of Sovi
Brottmekaniska processer ar något som intresserat människor i alla tider.
