Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

Development aid organizations are increasingly turning their focus on men and masculinities in the pursuit of women’s empowerment. Despite much effort to improve the lives of women, the hegemonic definition of empowerment in economic and individualistic terms have not been able to attack the unequal power structures between men and women, causing them to persist until this day. This essay explores

Background Increased postoperative cardiac troponin (cTn) independently predicts short-term mortality. Previous studies suggest that preoperative cTn also predicts major adverse cardiovascular events (MACE) and mortality after noncardiac surgery. The value of preoperative and perioperative changes in cTn as a prognostic tool for adverse outcomes has been sparsely investigated. Methods and findings

The #FridaysForFuture climate protests mobilized more than 1.6 million people around the globe in March 2019. Through a school strike, a new generation has been galvanized, representing a historical turn in climate activism. This wave of climate protest mobilization is unique in its tactics, global scope and appeal to teenage school students. Media coverage of these protests and high-level nationa

Recently, a haplotype of three single-nucleotide polymorphisms (tri-SNP) in intron 1 of the HLA-DRA1 gene was found to be strongly associated with type 1 diabetes risk in HLA-DR3/3 individuals. The tri-SNP reportedly function as “expression quantitative trait loci,” modulating HLA-DR and -DQ expression. The aim was to investigate HLA-DRA1 tri-SNPs in relation to extended HLA class II haplotypes an

A search for the standard model Higgs boson produced in association with a top-quark pair, ttH, is presented. The analysis uses 36.1 fb-1 of pp collision data at s=13 TeV collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The search targets the H→bb decay mode. The selected events contain either one or two electrons or muons from the top-quark decays, and are then cat

Universities have an important role in moving society towards a more sustainable future. However, this will require us to repurpose universities, reorienting and refocusing the different university domains (education, research, campus, and outreach) towards sustainability. The governance structures and processes used to embed sustainability into the activities and operations of the institution are

A search for the nonresonant production of Higgs boson pairs in the Formula Presented channel is performed using Formula Presented of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The analysis strategy is optimized to probe anomalous values of the Higgs boson self-coupling modifier Formula Presented and of the quarti

The aim of the study reported in this paper is to investigate how students understand continuity and differentiability during and after a calculus course. The students’ choices of representations, both claimed and acted, were also studied. The study is part of a larger study of four student groups taking a calculus course. 207 students answered a questionnaire during the course and of them, 11were

One could argue that the choice of software is a minor issue when setting up an institutional repository and that the big task is the one that follows, namely to induce the researchers to actually add their publications to the archive. It is true that getting the researchers to actually use the archive is the big challenge no matter what software you are using. Even so the choice of software and w

This paper is based on the keynote talk that I gave on the EAHIL+ICAHIS+ICLC 2015 Workshop in Edinburgh. A starting point for the talk was the theme for the Workshop: “Research-minded: supporting, understanding, conducting research”. Some features of qualitative research are presented and a number of methodsare mentioned before zooming in on interviewing, discussing some aspects of that method wit

Synovial fluid was collected from patients with recent knee injury and from patients with early or late stage osteoarthritis. Chondroitin sulfate-substituted aggrecan fragments present in these fluids, and in normal bovine synovial fluid, were purified by cesium chloride gradient centrifugation, enzymically deglycosylated and fractionated by gel filtration on Superose-12. Each sample contained two

Self-reported subjective cognitive difficulties (subjective deficits) and rumination are central residual cognitive symptoms following major depressive disorder (MDD). These are risk factors for more a severe course of illness, and despite the considerable relapse risk of MDD, few interventions target the remitted phase, a high-risk period for developing new episodes. Online distribution of interv

Care of older persons in community and primary care differs substantially between European countries, but most countries pursue the concept of “ageing in place”, meaning that most older people do not live in institutions. More and more older people are living alone. Relatives still play an important role in the care of older people, but it differs substantially within Europe, and will probably rem

This chapter examines elite polarisation as a challenge to governance in parliamentary democracies. We emphasise the distinction between ideological polarisation based on substantive policy disagreements from affective polarisation, characterised by identity-based animosity that creates barriers to cooperation even when policy compromise might otherwise be possible. While parliamentary regimes hav
