Structural changes in Ti1-xAlxN coated tool inserts used for turning in 316L stainless steel were investigated by XANES, EXAFS, EDS, and STEM. For coarse-grained fcc-structured Ti1-xAlxN coatings, with 0 ≤ x ≤ 0.62, the XANES spectrum changes with Al-content. XANES Ti 1s line-scans across the rake face of the worn samples reveals that TiN-enriched domains have formed during turning in Ti0.47Al0.53
To evaluate the role of polymer-surfactant interactions in drug solubilisation/stabilisation during the dissolution of spray-dried solid dispersions and their potential impact on in vivo drug solubilisation and absorption. Dissolution/precipitation tests were performed on spray-dried HPMC-Etravirine solid dispersions to demonstrate the impact of different surfactants on the in vitro performance of
Background: Radium-223, an alpha-emitting therapeutic radiopharmaceutical, prolongs overall survival (OS) in patients with symptomatic bone-predominant metastatic castration-resistant prostate cancer (mCRPC). PSMA PET/CT is a molecular imaging tool for whole-body imaging of prostate cancer and may inform on the mechanisms of radium-223 activity and treatment resistance in mCRPC patients. Methods:
Benthic fluxes of dissolved silicon (Si) from sediments into the water column are driven by the dissolution of biogenic silica (bSiO2) and terrigenous Si minerals and modulated by the precipitation of authigenic Si phases. Each of these processes has a specific effect on the isotopic composition of silicon dissolved in sediment pore fluids, such that the determination of pore fluid 30Si values can
BACKGROUND: This paper investigates the impact of a non-mandatory and age-specific social distancing recommendation on isolation behaviors and disease outcomes in Sweden during the first wave of the COVID-19 pandemic (March to July, 2020). The policy stated that people aged 70 years or older should avoid crowded places and contact with people outside the household.METHODS: We used a regression dis
AbstractPurpose: To evaluate the impact of cava balloon occlusion on the myocardium during endovascular repair of thoracic aortic pathologies.Material and methods: A prospective observational cohort study of 21 patients who underwent endovascular repair of aortic arch and thoracic aorta in a single tertiary referral center with use of inferior vena cava (IVC) balloon occlusion as a method of intra
This paper contributes to the debate on historical income inequality, and especially on the decrease in inequality found in industrialised countries during the first half of the twentieth century. We use new archival individual – and household-level data for taxpayers in Sweden’s third- largest city, Malmö, from 1900 to 1950. Previous research has established that Sweden had a distinctive downtur
In the present study, digestion pattern of purified bovine κ-casein (κ-CN) variants A, B, E as well as desialylated variant B, using INFOGEST 2.0 in vitro gastrointestinal digestion were investigated using peptidomics. Peptide profiles of the digests were identified and quantified using ion abundancies by liquid chromatography electrospray quadropole time of flight mass spectrometry (LC-ESI/Q-TOF
BACKGROUND: The benefit:risk profile of bivalirudin versus heparin anticoagulation in patients with non-ST-segment-elevation myocardial infarction undergoing percutaneous coronary intervention (PCI) is uncertain. Study-level meta-analyses lack granularity to provide conclusive answers. We sought to compare the outcomes of bivalirudin and heparin in patients with non-ST-segment-elevation myocardial
Background. Poor maternal self-rated health in healthy women is associated with adverse neonatal outcomes, but knowledge about self-rated health in pregnant women with congenital heart disease (CHD) is sparse. This study, therefore, investigated self-rated health before, during, and after pregnancy in women with CHD and factors associated with poor self-rated health. Methods. The Swedish national
The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on the world of sports due to periods of home quarantine, bans against public gatherings, travel restrictions, and a large number of postponed or canceled major sporting events. The literature hitherto is sparse, but early indications display signs of psychological impact on elite athletes due to the pandemic. However, b
The Quaternary East Asian summer rainfall evolution reconstructed with the Chinese speleothem δ18O records shows the consistency throughout the region of East Asia, and has long been considered equivalent to the monsoon intensity. Its variation and teleconnection with global climate were usually interpreted by the meridional shift of the intertropical convergence zone (ITCZ). However, many other p
This study investigates the use of mobile data to understand patterns of population movements and disease transmission during the Covid-19 outbreak. It also focuses on understanding the implications of using this data for individual privacy. Using a mixed methods approach, we present 10 rich qualitative interviews and 412 survey responses from participants across the Nordics. Our novel results sho
Eight healthy male subjects had intra-cortical bone-pins inserted into the proximal tibia and distal femur. Three reflective markers were attached to each bone-pin and four reflective markers were mounted on the skin of the tibia and thigh, respectively. Roentgen-stereophotogrammetric analysis (RSA) was used to determine the anatomical reference frame of the tibia and femur. Knee joint motion was
Anterior cruciate ligament injury (ACLi) reduces mechanical knee joint stability. Differences in muscle activation patterns are commonly identified between ACLi individuals and uninjured controls (CON); however, how and which of these differences are adaptations to protect the knee or adversely increase risk of joint instability remain unclear. Since the neuromuscular system integrates activity of
In this study, I reflect critically on my own experiences as a university teacher of students’ expressed knowledge about the academic subject of didactics at the beginning and end of their first semester as students in the Master’s Programme in Didactics. My reflections are made using a phenomenographic approach to learning, which regards learning as a qualitatively deeper and different way of und
Abstract When a child is hospitalized, the parents find themselves in an unfamiliar environment and their parental role changes. They are in a stressful and often anxiety-filled situation and it may be difficult for them to participate in decisions. The purpose of this study was to examine the extent to which parents participate in decisions during the course of events when their child is hospital
Purpose: The purpose of this study was to assess the alteration of retinal function by multifocal electroretinography and full-field electroretinography in patients with age-related macular degeneration treated with bevacizumab. Methods: We performed a prospective pilot study of 26 eyes of 26 previously treatment-naive patients with neovascular age-related macular degeneration receiving intravitre
