This special issue explores the extraordinary luminescence properties of metal halide perovskites. Metal halide perovskites have emerged at the forefront of next-generation, thin-film semiconductors for photovoltaic and light-emitting applications. These materials exhibit remarkable optoelectronic properties such as long charge carrier diffusion lengths and high radiative emission efficiencies, wh

Inflow Temperature is an important factor affecting the safety of propylene oxidation process. A soft-sensing model is proposed to monitor inflow temperature of the acrylic acid oxidation reactor. PSO-SVM method is used in the soft-sensing model. Five auxiliary variables, namely the top pressure P1, the top temperature T1, the bottom pressure P2, the bottom temperature T2 and the bottom temperatur

Choice blindness is a cognitive phenomenon describing that when people receive false feedback about a choice they just made, they often accept the outcome as their own. Little is known about what predisposes people to correct manipulations they are subjected to in choice blindness studies. In this study, 118 participants answered a political attitude survey and were then asked to explain some of t

We develop a parametric high-resolution method for the estimation of the frequency nodes of linear combinations of complex exponentials with exponential damping. We use Kronecker's theorem to formulate the associated nonlinear least squares problem as an optimization problem in the space of vectors generating Hankel matrices of fixed rank. Approximate solutions to this problem are obtained by usin

Young people today are on the move as never ever, both physical, mentally and literally. They reason is the need to gain the knowledge and experience needed to increase their employability. The world is open as ever before and everyone has today the possibilities to learn everything from everywhere at any time.

Background and purpose — Clindamycin has not been compared with other antibiotics for prophylaxis in arthroplasty. Since 2009, the Swedish Knee Arthroplasty Register (SKAR) has been collecting information on the prophylactic antibiotic regime used at every individual operation. In Sweden, when there is allergy to penicillin, clindamycin has been the recommended alternative. We examined whether the

Insta l lat ionen äger rum i Lunds univers i tets aula fredagen den 14 oktober 2011 kl 16.00 Professorsinstallation 3 Förord Välkomna till den högtidliga professors­ installationen! Ordet universitet kommer av det latinska universitas, som betyder ungefär helhet, det hela. Detta ord har samband med universus med betydelsen hel, allomfattande, egentligen vänd åt ett håll, liksom med universum och u

Eyja is a participatory piece about what it means to belong. The work is located in Hrísey, a fragile settlement where life and living conditions are fragile. Life on the island reflects the global projects facing the world in 2020. Visitors are invited to the island to examine their own ideas about self and society and about time and place.We sail from Árskógssandi and the work begins when you ge

The Adverse Outcome Pathways (AOPs) framework is pivotal in toxicology, but the, terminology describing Key Event Relationships (KERs) varies within AOP guidelines.This study examined the usage of causal, observational and predictive terms in AOP, documentation and their adaptation in AOP development. A literature search and text, analysis of key AOP guidance documents revealed nuanced usage of th

This study examines teachers’ use of evidence-based language learn­ing techniques in the classroom and possible impact on student ­engagement. Video recordings of nine primary school teachers conducting interactive book reading with their students were analyzed both according to the Communication Supporting Classroom Obser­vation Tool-Language Learning Interactions (CSCOT-LLI) and descriptively. Q

Lateglacial and Holocene summer sea-surface temperature (SST) variability in the northern North Atlantic was reconstructed based on diatom records from two sediment cores from the North Icelandic shelf. The temperature changes are discussed in relation to palaeoceanographic circulation patterns and past climatic changes. Modern diatom data from surface sediments from around Iceland and Southeast a

This article reflects on Max Weber’s idea of disenchantment in relation to the material turn within contemporary religious studies. In the first part, I return to the two most famous texts in which Weber uses the concept, with particular attention to the historical context in which these texts were penned. In the following part, I discuss some of the contemporary efforts to engage critically with

• The Arctic is continuing to warm faster than any other region on Earth, but key uncertainties remain in our knowledge of the Arctic carbon cycle. • We review the most current knowledge pertaining to estimates of arctic greenhouse gas components and discuss uncertainties associated with these measurements and models. • While the Arctic Ocean is consistently estimated as a carbon sink, we have yet

1. Salmeterol is a potent, selective and long acting beta 2-adrenoceptor agonist. In vitro, salmeterol exerts 'reassertion' relaxation of airways smooth muscle. Reassertion relaxation refers to the capacity of salmeterol to cause repeated functional antagonism of induced contraction when airway smooth muscle is intermittently exposed to, then washed free from, beta-adrenoceptor antagonists such as

AbstractDead standing trees (DSTs) generally decompose slower than wood in contact with the forest floor. In many regions, DSTs are being created at an increasing rate due to accelerating tree mortality caused by climate change. Therefore, factors determining DST fall are crucial for predicting dead wood turnover time but remain poorly constrained. Here, we conduct a re-analysis of published DST f

Carbonyl sulfide (COS) is a promising tracer for the estimation of terrestrial ecosystem gross primary production (GPP). However, understanding its non-GPP-related sources and sinks, e.g., anthropogenic sources and soil sources and sinks, is also critical to the success of the approach. Here we infer the regional sources and sinks of COS using continuous in situ mole fraction profile measurements
