We have imaged the emissions from excitons and free charges in a methylammonium lead bromide perovskite (MAPbBr3) crystal. In a direct band gap semiconductor, dynamics of excited electrons and holes in hybrid lead-halide perovskites is rather complex because of the formation of excitons and the presence of traps and structural inhomogeneities. A recent report by Nah et al. (Nah, S.; Spokoyny, B.;

Thermal performance curves (TPCs) are intended to approximate the relationship between temperature and fitness, and are commonly integrated into species distributional models for understanding climate change responses. However, TPCs may vary across traits because selection and environmental sensitivity (plasticity) differ across traits or because the timing and duration of the temperature exposure

BackgroundDense Non Aqueous Phase Liquids (DNAPL) such as chlorinated solvents are common pollutants stemming from different types of industries including dry cleaning facilities, and reports on cases showing serious risk to soil and ground water are frequent on a global scale. DNAPLs are especially problematic as they are denser than water and move down through the groundwater, not always followi

Syftet med forskningsrapporten är att bilda ett sammanhållet kunskapsläge över svensk gymnasial yrkesutbildning (skolförlagda yrkesprogram och lärlingsutbildning) som omfattar både forskning och regionala såväl som lokala satsningar för att stärka yrkesutbildningen. Forskningsrapporten omfattar två delar: (del 1) en kunskapssammanställning över den forskning som har bedrivits om gymnasial yrkesutb

BACKGROUND: Renal dysfunction is an established risk factor for cardiovascular disease, but early disease states in both organs are poorly studied.OBJECTIVE: This cross-sectional population-based study aims to investigate if there is an early association between kidney function and echocardiographic markers of cardiac structure and diastolic function.METHODS: The study population consisted of 1,50

Purpose: Low-risk prostate cancer is found in about half of newly diagnosed men subjected to PSA screening. Methods: To define the role of active surveillance and focal therapy in low- and intermediate-risk prostate cancers, an invited international panel of practicing physicians in the field of localized prostate cancer discussed the available literature in three consecutive meetings to come to a

Eucalyptus plantations have been established in many areas of the world due to their fast growth and profitability. In NW Spain, Eucalyptus plantations now cover a larger area than native forests. Although Eucalyptus plantations have been shown to affect biodiversity, relatively few studies have compared their effect on multiple taxonomic groups and different aspects of biodiversity. We compared h

To meet future challenges in urban development with denser housing and sustainable water resources, society needs to take actions. Densification of housing is met by expanding housing into old industrial areas often contaminated and water resources are already affected in some areas by over exploiting, pollutants spreading and a changing climate leading to changes in recharge.Growing concerns are

Det finns ett stort behov av en ökad förståelse för att de kemikalier vi använder, förr eller senare hamnar i vårt grundvatten. Grundvattendagarna i Lund avslutades med orden: ” Klockan är fem i tolv för grundvattnet i Sverige. Vad kan just du göra för att skydda vårt grundvatten?” Vi har idag över 60000 godkända kemikalier i Europa, med mer eller mindre känd påverkan på människors hälsa och milj

Background The coverage of prevention and treatment strategies for ischemic heart disease and stroke is very low in Ethiopia. In view of Ethiopia’s meager healthcare budget, it is important to identify the most cost-effective interventions for further scale-up. This paper’s objective is to assess cost-effectiveness of prevention and treatment of ischemic heart disease (IHD) and stroke in an Ethiop

BACKGROUND: Abiraterone acetate plus prednisone significantly improved radiographic progression-free survival compared with placebo plus prednisone in men with chemotherapy-naive castration-resistant prostate cancer at the interim analyses of the COU-AA-302 trial. Here, we present the prespecified final analysis of the trial, assessing the effect of abiraterone acetate plus prednisone on overall s

BACKGROUND: Enzalutamide is an oral androgen-receptor inhibitor that prolongs survival in men with metastatic castration-resistant prostate cancer in whom the disease has progressed after chemotherapy. New treatment options are needed for patients with metastatic prostate cancer who have not received chemotherapy, in whom the disease has progressed despite androgen-deprivation therapy.METHODS: In
