White dwarf stars represent the last evolutionary stage of most stars in the Universe. As many of half of these stars are known to have metals in their atmospheres, that must have entered the atmosphere recently. Some also have observable debris discs, hinting that remnant exoplanets provide an important puzzle piece. However, we do not know the full extent of their role, as it is very hard to obs
The construction sector contributes around 37 % of global CO2 emissions, highlighting the need for de-carbonization. Part of the emissions originate in the use of diesel-driven heavy equipment. Considering the fast pace of transitioning from fossil fuels to electricity in other vehicle sectors, this may be a possible path for heavy equipment, considering the introduction of electric heavy equipmen
Uppsatsen som har författats behandlar våld mot tjänsteman med särskilt fokus på vilken betydelse kroppskamerabevisning har i tillämpningen av lagrummet. Syftet är att analysera hur våld mot tjänsteman ska förstås och vidare se prov på hur kroppskamera påverkar domstolarnas bedömning av händelseförloppet i praktiken. Arbetet kombinerar ett rättsdogmatiskt arbetssätt med en empirisk undersökning avThis thesis examines the offence of violence against a public official, with a particular focus on the role of body-worn camera evidence in the application of the law. The purpose of the thesis is to analyse how violence against a public official should be understood and to examine how body-worn cameras affect the courts’ assessment of events in practice. The study combines a legal analysis with a
This thesis aimed to examine the conditions under which neutrality is respected in war and, by applying alliance- and shelter theory, to analyze how the neutrality of Sweden and the Netherlands was respected during the First and Second World Wars. The study addressed two research questions which are; Under what conditions is neutrality respected in war? and How can alliance theory and shelter theo
During the 2015–2018 data-taking period, the Large Hadron Collider delivered proton-proton bunch crossings at a centre-of-mass energy of 13 TeV to the ATLAS experiment at a rate of roughly 30 MHz, where each bunch crossing contained an average of 34 independent inelastic proton-proton collisions. The ATLAS trigger system selected roughly 1 kHz of these bunch crossings to be recorded to disk. Offli
When discussing the relationship between religion and LGBTQIA+ rights in Europe today, the two are often framed by both religious and secular representatives as oppositional forces. While the rights of sexual and gender minorities are frequently described as symbols of progress and modernity within liberal democracies, religious communities and traditions are commonly portrayed as defenders of tra
Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which
We investigate the role of the coupling between a spin-orbit coupled semiconductor nanowire and a conventional s-wave superconductor on the emergence of the topological superconducting phase with Majorana bound states in an applied magnetic field. We show that when the coupling is strong, the topological phase transition point is very sensitive to the size of the superconductor and in order to rea
Introduction: In Sweden, during specialty training, the nurse anesthetist learns how to ensure patient safety in a health-care setting by implementing the surgical checklist measures during perioperative care. To date, there are still considerable shortcomings when it comes to implementing these patient safety measures in Swedish hospitals.Aim: The purpose of this study is to describe the use of t
Natural selection on floral scent composition is a key element of the hypothesis that pollinators and other floral visitors drive scent evolution. The measure of such selection is complicated by the high-dimensional nature of floral scent data and uncertainty about the cognitive processes involved in scent-mediated communication. We use dimension reduction through reduced-rank regression to jointl
Objective: The purpose of this study was to explore the feasibility to determine regional diagnostic reference levels (RDRLs) for paediatric conventional and CT examinations using the European guidelines and to compare RDRLs derived from weight and age groups, respectively. Methods: Data were collected from 31 hospitals in 4 countries, for 7 examination types for a total of 2978 patients. RDRLs we
Purpose: The purpose of this article is to offer new insights into crisis communication in service ecosystems. The authors present a framework to conceptually categorize service crises and then analyze key aspects of crisis communication among different stakeholders in a service ecosystem. Design/methodology/approach: Building on crisis communication and service ecosystems research, we propose a f
We highlight important assumptions associated with the research program in sustainability science developed around “corporate biosphere stewardship” and the promise of “science-business initiatives.” In doing so, we interrogate a central concept in this research, “keystone actors.” We analyze the program based on associated research outputs and communications, focusing on three key challenges 1) i
Background and purpose - Intramedullary nails (IMN) have become increasingly common as treatment for trochanteric hip fractures (THF) although they are costlier, and without proven superiority compared with sliding hip screws (SHS). We investigated whether the 2 methods differ in terms of short-term mortality when used in fractures where both methods are suitable. Patients and methods - We extract
High-throughput sequencing has become a prominent tool to assess plant-associated microbial diversity. Still, some technical challenges remain in characterising these communities, notably due to plant and fungal DNA co-amplification. Fungal-specific primers, Peptide Nucleic Acid (PNA) clamps, or adjusting PCR conditions are approaches to limit plant DNA contamination. However, a systematic compari
