Metal halide perovskites attract significant interest due to their remarkable performance in optoelectronic devices. However, the gap in understanding the relationship between their nanoscale structure and properties limits their application towards novel devices. In this work, twinned ferroelastic domains in single 500 nm CsPbBr3 particles are studied with 3D Bragg coherent x-ray diffraction imag

Är fönsteröppningar självklara? I så fall borde vi kunna svara påfrågan varför, men det är inte helt lätt. Bokens huvudbudskap är attfönsteröppningen tycks spela en nyckelroll för trivseln i hemmetinte minst för att den påverkar flera aspekter av boendekomfort.Boken vänder sig till de som på olika sätt påverkar ljus- ochmörkerförhållanden i bostäder och därigenom indirekt boendeshälsa och välbefin

The development of Swedish linguistics during the 20th century reflects international development. The century started with focus on language history described according to the theory of sound laws. It is reasonable to call the period around the turn of the century the Golden Age of Nordic philology; characterized by the work of Adolf Noreen; Axel Kock and Elof Hellquist who clarified the basic de

Background and purpose - Hip arthroscopies (HAs) have increased exponentially worldwide and are expected to continue rising. We describe time trends in HA procedures in Sweden (10 million inhabitants) between 2006 and 2018 with a focus on procedure rates, surgical procedures, and patient demographics such as age and sex distribution.Patients and methods - We retrospectively collected data from the

The implementation of multidisciplinary research approaches is an essential prerequisite to obtain comprehensive insights into the life and works of the old masters and their timeline in the production of the arts. In this study, traditional art history, cultural heritage, and natural science methods were combined to shed light on an Adoration of the Shepherds painting by Jacques Jordaens (1593–16

BackgroundThe efficacy of technology-delivered cognitive-behavioral therapy (tCBT) for pediatric anxiety disorders (ADs) is uncertain as no meta-analysis has examined outcomes in trials that used structured diagnostic assessments at pre- and posttreatment.MethodsWe carried out a systematic review and meta-analysis of randomized controlled trials (RCTs) of tCBT for pediatric ADs that included parti

Platelet transfusion refractoriness is a serious clinical concern that complicates the management of thrombocytopenic patients. Previous studies have suggested a potential role for both complement and platelet activation based on in vitro analyses of platelet concentrates. In this study, the post-transfusion platelet response, as indicated by the corrected count increment at 1 and 24 h after proph

Green fluorescent protein (GFP) from Aequorea victoria was used as an in vivo reporter protein when fused to the carboxy-terminus of the Pho84 phosphate permease of Saccharomyces cerevisiae. Both components of the fusion protein displayed their native functions and revealed a cellular localization and degradation of the Pho84-GFP chimera consistent with the behavior of the wild-type Pho84 protein.

Previous research on variation in patient reported experience measures (PREMs) suggest that it is important to be cautious when using comparative information about patients’ experiences, collected via patient surveys, to assess provider performance. Not all factors associated with variation in PREMs are related to factors that providers themselves can control. This study explores if structural cha

PURPOSE: To derive Regional Diagnostic Reference Levels (RDRL) for paediatric conventional and CT examinations using weight-based DRL curves and compare the outcome with DRL derived using the weight groups.METHODS: Data from 1722 examinations performed at 29 hospitals in four countries were included. DRL was derived for four conventional x-ray (chest, abdomen, pelvis, hips/joints) and two types of

The aim of this study is to implement lifetime attributable risk (LAR) predictions for radiation induced cancers for Swedish cohorts of patients of various age and sex, undergoing diagnostic investigations by nuclear medicine methods.METHODS: Calculations are performed on Swedish groups of patients with Paget's disease and with bone metastases from prostatic cancer and diagnosed with bone scintigr

Imaging optimisation can benefit from combining structured data with qualitative data in the form of audio and video recordings. Since video is complex to work with, there is a need to find a workable solution that minimises the additional time investment. The purpose of the paper is to outline a general workflow that can begin to address this issue. What is described is a data management process

PURPOSE: Interventional radiology techniques cause radiation exposure both to patient and personnel. The radiation dose to the operator is usually measured with dosimeters located at specific points above or below the lead aprons. The aim of this study is to develop and validate two fast Monte Carlo (MC) codes for radiation transport in order to improve the assessment of individual doses in interv

The present study focuses on introducing the concept of optimisation and proposing a model, including evaluation of image quality, to be used in the clinical routines where image-guided intervention is being performed. The overall aim of the study was to develop a model for evaluating the use of imaging in X-ray-guided interventional procedures and its possible implications on optimisation of radi

Exposure levels to staff in interventional radiology (IR) may be significant and appropriate assessment of radiation doses is needed. Issues regarding measurements using physical dosemeters in the clinical environment still exist. The objective of this work was to explore the prerequisites for assessing staff radiation dose, based on simulations only. Personal dose equivalent, Hp(10), was assessed

This chapter is focusing on membrane applications in the sugar and brewing industries. Both industries are established global industries operating with large process streams and having a wide range of separation needs. Despite these needs, membrane processes are still in their infancy in these two industries. The key challenge of membrane processes in these industries is membrane fouling due to th

Severe episodic air pollution blankets entire cities and regions and have a profound impact on humans and their activities. We compiled daily fine particle (PM2.5) data from 100 cities in five continents, investigated the trends of number, frequency, and duration of pollution episodes, and compared these with the baseline trend in air pollution. We showed that the factors contributing to these eve
