Railways play an important role in the energy transition by offering a low-carbon, energy-efficient means of transporting goods, people, and services. However, this role is increasingly at risk as extreme weather events associated with a changing climate grow in severity and frequency, compounded by uncertainties in future climate conditions.This thesis aims to advance the understanding of climate

T.M. Scanlon’s version of contractualism has emerged as one of the most well-developed challengers to consequentialism. According to one of contractualism’s most appealing features—the Individualist Restriction—the justifiability of our actions depends solely on the personal reasons of single individuals. While it allows contractualism to avoid many of consequentialism’s most implausible implicati

Denna avhandling undersöker styrningen av koldioxidavskiljning och -lagring (CCS) i den nuvarande fasen av policydriven implementering inom europeisk klimatpolitik. Min forskning placeras i mellan etablerad kritik av CCS och dess framväxande, centrala roll i bindande nettonollstrategier. Jag intar en kritiskt pragmatisk hållning som erkänner att CCS är en omtvistad teknik som innebär risker för inThis thesis examines the governance of Carbon Capture and Storage (CCS) technology in its current phase of policy-driven deployment within European climate policy. Positioned in the gap between established critique of CCS and its newly central role in binding net-zero strategies, my research adopts a critical-pragmatic stance to acknowledge that CCS is a contentious technology embodying risks of c

Kapitlet redogör för hur Universitetsbibliotekets samling av vardagstryck (tidigare Okatalogiserat tryck eller Småtrycket) kunde användas som källmaterial i prishistorisk forskning som bidrog till konstruktionen av Sveriges historiska nationalräkenskaper. I källmaterialet dök Emil Svensson i Lönneberga oväntat upp som en recensent av Öfverums slåttermaskin 1892 och han uppskattade särskilt maskine

Modern battery chargers require AC-DC converters with high input power quality, nearly unity power factor, and low current harmonics to meet grid standards such as IEC 61000-3-2. This paper proposes a two-stage charger topology: a front-end bridgeless interleaved boost PFC converter followed by a synchronous buck DC-DC stage. The interleaved boost stage reduces input current ripple and losses whil

BACKGROUND: There is limited information concerning the current practice of intraoperative mechanical ventilation in obese patients, and the optimal ventilator settings for these patients are debated. We investigated intraoperative ventilation parameters and their associations with the development of postoperative pulmonary complications (PPCs) in obese patients.METHODS: We performed a secondary a

The market for fully electrified vehicles is expanding fast. The number of sources and loads that are connected to the vehicles traction voltage systems (TVS) are increasing and thus also the ElectroMagnetic Compatibility (EMC) requirements on these sources and loads. These requirements should make sure that neither function nor lifetime of any source or load is severely affected by another. The C

Objective This study aims to investigate whether oral fluoroquinolone use is associated with an increased risk of aortic and mitral valve regurgitation. Design A nationwide cohort study based on linked healthcare register data encompassing patient characteristics, prescription data and cases of aortic and mitral valve regurgitation. Setting Sweden, 2006–2018. Participants Study participants were a

Background. Seeking to clarify the parent-offspring transmission of Major Depression (MD) and type I Bipolar Disorder (BD), we examined offspring MD and BD risk in five informative parental pairs: Unaffected x MD, Unaffected x BD, MDxMD, MDxBD and BDxBD. Methods. We identified 289,637 individuals born in Sweden 1970-1990, followed through 2018, from parents with MD and/or BD identified from Swedis

Nickel phosphides are promising earth-abundant, low-cost catalysts for hydrogen/oxygen evolution reactions and CO2 reduction. However, their formation mechanisms remain poorly understood and difficult to control. This particularly applies to mechanisms determining phase evolution, crystallinity, and morphology under reactive conditions, factors that critically influence catalytic activity and stab

Standard quantum measurements are projective. However, the full scope of quantum measurements is represented by positive operator-valued measures (POVMs) and many of these break the limitations of projective measurements as resources in quantum information. It is therefore natural to consider how accurately an experimenter with access only to projective measurements and classical processing can si

Animals have evolved multiple sensory systems that can acquire environmental information guiding their behaviour, allowing them to adapt physiological parameters to current conditions. However, over the past century, anthropogenic changes have increasingly made information on environmental conditions less reliable, by introducing novel elements (such as synthetic chemicals or artificial light), by

Bakgrund: Preoperativ anemi är en välkänd riskfaktor för ett sämre kirurgiskt utfall. Hos patienter med flera riskfaktorer för postoperativa komplikationer är anemi den som lätt kan hanteras inom den tillgängliga tidsramen före operationen. I de fall denna hantering inte genomförs är det dock viktigt att förstår dess negativa påverkan jämfört med andra riskfaktorer. Denna studie syftade till att u

Bakgrund Inläggning av central venaccess, exempelvis central venkateter (CVK), är en invasiv åtgärd som kräver sterila betingelser för att förhindra introduktionen av mikroorganismer till blodbanan med en ökad risk för kolonisation respektive kateterrelaterad infektion. Med ett strukturerat arbetskoncept kan man uppnå en infektionsincidens nära noll. Flera aspekter är betonade i riktlinjerna, men

The decarbonisation of industry, which is a significant contributor to greenhouse gas emissions, is closely linked to the energy system and its transformation. This study quantifies the impacts of industrial decarbonisation on the European energy system, considering uncertainties in electricity and hydrogen demand and constraints on renewable energy sources (RES) deployment and cross-border infras

Electronics repair is a core component of a circular economy, yet the many social, technical, and financial barriers limit the widespread adoption of repair practices along the value chain. The high complexity of electronics, reinforced by product design choices, and a perpetuating culture of consumption has normalised replacement when a fault occurs. Similarly, a lack of technical knowledge, unce
