Photoluminescence (PL) spectra from thin films (TFs) and bulk crystals (BCs) of hybrid organo-halide perovskites are significantly different, the origin of which and their impact on the efficiency of the perovskite-based photoactive devices have been debated. We have used two-photon PL to study the temperature-dependent changes in the spectra of the TFs and the BCs of methylammonium lead bromide (

Background: Pancreatoduodenectomy is associated with a high risk of complications. The aim was to identify preoperative risk factors for major intraoperative bleeding. Methods: Patients registered for pancreatoduodenectomy in the Swedish National Pancreatic and Periampullary Cancer Registry, 2011 to 2016, were included. Major intraoperative bleeding was defined as ≥1000 ml. Univariable and multiva
This paper presents results from an experimental assessment of glued-in rods in cross laminated timber (CLT). For the purposes of the study more than 60 pull–pull tests were performed, where the specimens varied in terms of bonded-in length (from 80 to 400 mm), rod diameter (16–24 mm) and rod-to-grain angle (parallel and perpendicular). Several different failure modes that are not common for other
The lipid-protein mixture that covers the lung alveoli, lung surfactant, ensures mechanical robustness and controls gas transport during breathing. Lung surfactant is located at an interface between water-rich tissue and humid, but not fully saturated, air. The resulting humidity difference places the lung surfactant film out of thermodynamic equilibrium, which triggers the buildup of a water grad
Rules-based fiscal policy is under threat. Over the last two decades, it proved frustratingly complicated to strike the right balance between three essential properties of sound fiscal policy rules: simplicity, flexibility, and enforceability. Simplicity has been sacrificed to ensure that more contingent (i.e. flexible) rules remained enforceable. The resulting arrangements have failed to adequate
The influence of hunger level and predation risk on habitat choice and foraging in crucian carp, Carassius carassius, were studied in a laboratory experiment. Experiments were carried out in aquaria with or without a predator (pike, Esox lucius). Habitat use and foraging activity of three-fish foraging groups of either fed or hungry crucian carp were studied. Fish were allowed to choose between an
Purpose: The primary goal was to validate a Danish translated version of the Catquest-9SF by Rasch analysis. The secondary goal was to investigate whether preoperative Catquest-9SF scores, best-corrected visual acuity, comorbidity, gender, age or corneal astigmatism could predict improvements in subjective outcome. Methods: In a prospective trial, 250 patients eligible for cataract surgery were in
Purpose: To investigate the effects of intravitreal neuropeptide Y (NPY) treatment following acute retinal ischaemia in an in vivo porcine model. In addition, we evaluated the vasoconstrictive potential of NPY on porcine retinal arteries ex vivo. Methods: Twelve pigs underwent induced retinal ischaemia by elevated intraocular pressure clamping the ocular perfusion pressure at 5 mmHg for 2 hr follo
Objectives: International evidence suggests that rates of inability to work because of illness can change over time. We hypothesised that one reason for this is that the link between inability to work and common illnesses, such as musculoskeletal pain and mental illness, may also change over time. We have investigated this in a study based in one UK district. Methods: Five population surveys (span
The inhibition of unproductive motor movements is regarded as a fundamental cognitive mechanism. Recently it has been shown that species with large absolute brain size or high numbers of pallial neurons, like great apes and corvids, show the highest performance on a task purportedly measuring this mechanism: the cylinder task. In this task the subject must detour a perpendicularly oriented transpa
Many groups of immigrants have worse health than the native population in the host countries. One possible explanation for this is that immigrants are disadvantaged in the labor market, since it has been shown that both precarious and locked-in labor market position can be associated with health problems. However, no published study to date has analyzed the prevalence or consequences of locked-in
This paper focuses on the effects of sanctions on Swedish firms' sales across markets, as well as sanctions’ effects on their domestic production. As a case study, the paper uses sanctions imposed on Russia and by Russia in 2014. The results suggest that the total costs of these sanctions due to a drop in sales for Swedish firms amounts to around 1 billion SEK in 2013 prices, which implies a rathe
