Over the last years, there have been huge research efforts in the synthesis of advanced nanoparticle heterostructures to promote their performance in photocatalysis.[1] Especially, the combination of metals with semiconductors has been identified as a potential approach to enhance the photocatalytic activity via efficient charge carrier separation enabled by plasmon- exciton coupling.[2] The physi
Widowhood involves many practical challenges next to the emotional impact of bereavement. Remarriage to a blood relative of a deceased spouse can often help a bereaved spouse to solve issues related to inheritance, child care, and comfort in a stressful period. A study of 15,540 widowers and 18,837 widows in the Dutch province of Zeeland—of whom about 8,000 men and 5,000 women eventually remarried
Alexandra Kollontai was the Soviet ambassador to Sweden in the years1930 to 1945. In Sweden she gained many friends in the peace- and women’s movement and among these were several female physicians. This article describes and investigates the friendships between Swedish female physicians and Alexandra Kollontai. The three physicians focused on are Ada Nilsson (1872–1964), Andrea Andreen (1888–1972
AimThe aim of this study was to investigate if prophylactic treatment in severe haemophilia impact on bone mineral densisty (BMD) in adults with haemophilia A/B.MethodsSubjects with haemophilia (n = 120) underwent bone-density measurement and clinical data was collected. BMD in subjects with severe haemophilia on high-dose prophylaxis (n = 41) was compared to BMD in subjects with mild haemophilia
While striving for more competitive products as well as reaching the Global Sustainable Development Goals, automotive powertrain manufacturers increase the demands on gears, which translates to decreased manufacturing error tolerances. Too tight tolerances may, however, counteract the goal if it leads to increased material and energy consumption due to unjustified scrapping. This paper presents a
The main objective was to develop a wipe sampling test to measure surface contamination of the most frequently used antineoplastic drugs (ADs) in Swedish healthcare and, furthermore, to develop an analysis method sensitive enough to assess low levels of contamination. Two wipe sampling tests with separate sample processing methods assessing (i) cyclophosphamide (CP), ifosfamide (IF), 5-fluorouraci
Epilepsy is a complex disorder affecting the central nervous system and is characterised by spontaneously recurring seizures (SRSs). Epileptic patients undergo symptomatic pharmacolog-ical treatments, however, in 30% of cases, they are ineffective, mostly in patients with temporal lobe epilepsy. Therefore, there is a need for developing novel treatment strategies. Transplantation of cells releasin
Compacted graphite iron (CGI) is an intermediate material between conventional grey cast iron and the stronger, more wear resistant ductile iron, making it a suitable material choice for different automotive applications. The improved material properties of CGI as to conventional grey cast iron makes it more difficult to machine, and finding a suitable tool material with low wear rates is a challe
AbstractThis study investigates the establishment and significance of United Nations (UN) Day, October 24, in Swedish primary and secondary schools from 1948 to 1963. This article conceptualizes the celebrations as knowledge rituals, educative events that foreground practices of knowledge-sharing, reinforcing social bonds and enhancing collective understanding. UN Day knowledge rituals combined ceThis study investigates the establishment and significance of United Nations (UN) Day, October 24, in Swedish primary and secondary schools from 1948 to 1963.This article conceptualizes the celebrations as knowledge rituals, educative events that foreground practices of knowledge-sharing, reinforcing social bonds and enhancing collective understanding.

Objective. Prior incidence estimates of psoriatic arthritis (PsA) vary considerably. We aimed to assess the annual incidence of clinically diagnosed PsA among adults in Sweden in 2014-2016, overall and stratified by age/sex/education/geography, and to investigate potential time trends in incidence in 2006-2018. Use of disease-modifying antirheumatic drugs (DMARDs) during the 2 years after diagnosi
We study the association between childhood neighborhood socioeconomic status (SES) (ages 1-15) and hospitalization with preventable-type disease in adulthood, using geocoded longitudinal microdata for a Swedish city (1939-1967) linked to national registers (1973-2015). Observing the full residential histories at the address level for the entire population, we construct dynamic and cumulative indiv
BackgroundCritical COVID-19 is associated with high mortality, and acute kidney injury (AKI) is common. Endostatin has emerged as a promising prognostic biomarker for predicting AKI and mortality in intensive care. This study aimed to investigate plasma endostatin at intensive care unit (ICU) admission as a biomarker for AKI, renal replacement therapy (RRT), and 90-day mortality in COVID-19.Method
Background: Certain species from the normal respiratory tract microbiota have recently been proposed to positively influence human health. Corynebacterium propinquum and C. pseudodiphtheriticum (Corynebacteria) are two Gram-positive species that frequently colonize the upper respiratory tract and strongly associate with a reduced incidence of respiratory tract infections. The specific role of Cory
Bimetallic nanoparticles exhibit unique physicochemical characteristics that often translateinto functional properties surpassing those of their monometallic counterparts. The abilityto precisely tailor these characteristics enables fine-tuning of their properties for targetedapplications. This doctoral thesis investigates the engineering of bimetallic nanoparticlesvia spark ablation, a continuous
In electric passenger vehicles with modest performance the drivetrain usually consists of one inverter, one electrical machine and a single-speed transmission. The inverter is typically a two-level inverter using either Si IGBT transistors with an anti-parallel Si diode, or a SiC MOSFET transistor with or without an anti-parallel diode. The benefits of selecting SiC MOSFET as semiconductor technol
The enhancement and protection of coastal ecosystems that sequester carbon for climate change mitigation have developed over the last 15 years, and today are part of climate governance. After an initially challenging start in terms of policy interest, Blue Carbon is now included in some countries’ national inventories, and as such, enters the global sums of emissions and sinks, and becomes relevan
Airborne depth sounding lidar has proven to be a valuable sensor for rapid and accurate sounding of shallow areas. The received lidar pulse echo contains information of the sea floor depth, but also other data can be extracted. We currently perform work on bottom classification and water turbidity estimation based on lidar data. In this paper we present the theoretical background and experimental
