Perovskite nanocrystal superlattices are being actively studied after reports have emerged on collective excitonic properties at cryogenic temperatures, where energetic disorder is minimized due to the frozen lattice vibrations. However, an important issue related to structural disorder of superlattices at low temperatures has received little attention to date. In this work, it is shown that CsPbB

Background Transcatheter aortic valve implantation (TAVI) is an increasingly important treatment option for patients with severe aortic stenosis. Its best implementation is debated, as few centres with high volumes are associated with better outcomes, while centralization might lead to an inferior availability of treatment for patients living far away. The aim of this study was to investigate the

Aim: Assess the prognostic ability of a non-highly malignant and reactive EEG to predict good outcome after cardiac arrest (CA). Methods: Prospective observational multicentre substudy of the “Targeted Hypothermia versus Targeted Normothermia after Out-of-hospital Cardiac Arrest Trial”, also known as the TTM2-trial. Presence or absence of highly malignant EEG patterns and EEG reactivity to externa

Bakgrund: Äldre är en växande grupp av vårdsökande på akutmottagningarna och resurserna ökar inte i takt med det ökade behovet av vård. Vistelsetiden på akutmottagningen ökar årligen och hårdast drabbas äldre patienter. Att besöka akutmottagningen kan vara en utmaning för de äldre i den hektiska miljön som finns på akutmottagningen. Syfte: Syftet med studien var att undersöka hur äldre upplevde atBackground: The elderly are a growing group of care seekers in the emergency departments and the resources do not increase in pace with the increased need for care. The length of stay in the emergency department increases annually, and older patients are hit hardest. Visiting the emergency department can be a challenge for the elderly in the busy environment found in the emergency department. Purp

In the 20th century, big innovative steps were made in the cutting tool industry. Two Swedish companies, today Seco Tools AB and Sandvik Coromant, were some of the first companies to use cemented carbide as tool material. In 1969 Sandvik Coromant introduced a layer of titanium carbides on top of a cemented carbide substrate to improve its performance. Coating materials have been continuously devel

This study considers perceptions of group teaching among classical instrumental music teachers in Swedish art and music schools. Quantitative and qualitative data were collected using a survey of music teachers in a region of Sweden and analysed using a mixed methods approach. Communities of practice and communities of musical practice served as the theoretical framework for both the deductive and

This research addresses action research (AR) as a meta-methodology and uses an operations development project as an illustration to provide some insights on AR as a meta-methodology. First, we report on a six-month action research (AR) project concerning analysing and improving production and inventory performance in an industrial firm in the food and beverage industry. The implementation of a new

In this study, a solar dryer incorporating a flat plate heat exchanger to recover heat from exhaust air was investigated to explore the usability of different types of collectors in the system. Their usability was further evaluated through economic and environmental analyses. Moreover, the thermodynamic performance of the solar dryers was evaluated under two weather conditions in Nepal. Apple dryi

Objective: Occupational exposure to welding fumes is linked to a higher risk of cardiovascular disease; however, the threshold exposure level is unknown. Here, we aimed to identify changes in proteins associated with cardiovascular disease in relation to exposure to welding fumes. Methods: Data were obtained from two timepoints six years apart for 338 non-smoking men (171 welders, 167 controls); o

Changes in biomarker levels of Alzheimer’s disease (AD) reflect underlying pathophysiological changes in the brain and can provide evidence of direct and downstream treatment effects linked to disease modification. Recent results from clinical trials of anti–amyloid β (Aβ) treatments have raised the question of how to best characterize the relationship between AD biomarkers and clinical endpoints.

Market failure is a concept invoked in both economics and public policy to justify governmental interventions in the marketplace. Drawing on more than five years of qualitative research on public transport in Stockholm, this paper explores how market failure, operating as a form of folk theory within public policy, informed a legal reform. This reform aimed to reconfigure an established contractua

Inequality is ubiquitous in time and space. It is often measured simply as differences in incomes between various groups, but the phenomenon is more complex than so. Inequality is a many-faceted phenomenon that manifests itself in a number of ways. It shows up in a variety of contexts, for example gender, age, origin, ethnicity, disability, sexual orientation, class, religion and place. The presen

Traditional methods for measuring chemical exposure have challenges in terms of obtaining sufficient data; therefore, improved methods for better assessing occupational exposure are needed. One possible approach to mitigate these challenges is to use self-monitoring methods such as sensors, diaries, or biomarkers. In the present study, a self-monitored method for measuring soot exposure, which inc

Shadi Hamid proposes “democratic minimalism” as a system and means of governing and rotating power with no prejudice to substantive ideological outcomes. Democratic minimalism is meant to decouple the question of actualizing an ideal society, even a liberal one that provides maximum freedom for the maximum groups of people, from the mechanism of transferring power between groups with opposing beli

Atomic layer deposition (ALD) has been an attractive tool in the fabrication of Pt thin layers and nanoparticles. In this work, the surface chemistry of Pt ALD through the MeCpPtMe3/N2-plasma (N2*) and the MeCpPtMe3/NH3-plasma (NH3*) processes at 300 °C have been investigated in detail using in vacuo X-ray photoelectron spectroscopy (XPS) during the ALD process, so that the evolution of surface sp

The crucial role of aerobic energy production in sustaining eukaryotic life positions mitochondrial processes as key determinants of an animal's ability to withstand unpredictable environments. The advent of new techniques facilitating the measurement of mitochondrial function offers an increasingly promising tool for conservation approaches. Herein, we synthesize the current knowledge on the link

Background: The Duke criteria for diagnosing infective endocarditis (IE) were recently updated by the International Society for Cardiovascular Infectious Diseases (ISCVID) with the purpose of enhancing diagnostic specificity and sensitivity. This study investigated the performance of the Duke-ISCVID criteria in relation to previous criteria. Method: This retrospective single centre cohort study in

Två böcker som analyserar västvärldens predikament efter Trump I är väl värda att begrunda även om de farhågor författarna ventilerar har antagit oanade proportioner efter Trump II: Peter Heathers och John Rapleys Why Empires Fall (Allen Lane 2023) och Martin Wolfs The Crisis of Democratic Capitalism (Penguin Books 2024).
