Fundmental comprehension of light-induced processes in perovskites are still scarce. One active debate surrounds the influence of excess lead iodide (PbI2) on device performance, as well as optoelectronic properties, where both beneficial and detrimental traits have been reported. Here, we study its impact on charge carrier recombination kinetics by simultaneously acquiring the photoluminescence q
Partiklar i atmosfären – aerosoler – har en avkylande effekt på jordens klimat. Aerosolernas sammanlagda effekt bedöms i IPCCs femte stora rapport, AR5, som något mindre än vad som rapporterades i 2007 i AR4. Partiklars avkylande effekt har troligen i viss mån motverkat växthusgasutsläppens uppvärmande påverkan. Vi kan dock inte förlita oss på sådan draghjälp i klimatarbetet. Internationella övere
Background: Anoxic brain injury is the primary cause of death after resuscitation from out-of-hospital cardiac arrest (OHCA) and prognostication is challenging. The aim of this study was to evaluate the potential of two fragments of tau as serum biomarkers for neurological outcome. Methods: Single-center sub-study of 171 patients included in the Target Temperature Management (TTM) Trial randomly a
This technical report describes JitterTime, a Matlab toolbox for calculating the time-varying state covariance of a mixed continuous/discrete linear system driven by white noise. It also integrates a quadratic cost function for the system. The passing of time and the updating of the discrete-time systems are explicitly managed by the user in a simulation run. Since the timing is completely handled
We theorize that three distinct structures of democratic constraint explain why more democratic dyads do not engage in military conflict with each other. We build on earlier theories that focused on electoral and horizontal accountability. We add a new dimension—the social accountability provided by an active civil society. Using several new measures from the Varieties of Democracy (V-Dem) data se
On-going debates within feminist and social science research are increasingly highlighting the need for reflexive scholarship (particularly within qualitative research) – both in terms of considering the emotionality of the research process (Brownlie 2014, Burkitt 2012, Doucet 2008, Holland 2005, Mauthner and Doucet 2003) and in terms of applying an intersectional lens and discussing researchers’
Den observerade globala uppvärmningen sedan industrialismens början uppgår nu till nästan en grad, havsnivån har stigit och Arktis havsis och glaciärer smälter. Hur stor klimatförändringen och dess effekter till slut blir beror främst på utvecklingen av de klimatpåverkande utsläppen, speciellt koldioxid. De globala utsläppen behöver över tid begränsas till 3700 miljarder ton koldioxidekvivalenter,
OBJECTIVE: To assess the efficacy of arthroscopic subacromial decompression (ASD) by comparing it with diagnostic arthroscopy, a placebo surgical intervention, and with a non-operative alternative, exercise therapy, in a more pragmatic setting. DESIGN: Multicentre, three group, randomised, double blind, sham controlled trial. SETTING: Orthopaedic departments at three public hospitals in Finland. P
Att begränsa den globala uppvärmningen till under två grader - tvågradersmålet - är ett övergripande mål i klimatpolitiken såväl internationellt som i Sverige. Tvågradersmålet kan ses som ambitiöst jämfört med globala trender idag, men den utesluter inte alla klimateffekter. Om målet är tillräckligt beror alltså även på vilka risker vi kan acceptera och vad vi kan åtgärda med anpassning. För att k
In the present work, a novel burner capable of complete pre-vaporization and stationary combustion of diesel fuel in a laminar diffusion flame has been developed to investigate the effect of the chemical composition of diesel fuel on soot formation. For the characterization of soot formation during diesel combustion we performed a comprehensive morphological characterization of the soot and determ
