In the beam dynamics design and modelling of the Eu- ropean Spallation Source (ESS) Drift Tube Linac (DTL) simplified models have been used for the focusing and ac- celerating elements. Since the high current requires precise control of the beam to analyze the losses it is useful to per- form the beam dynamics simulations by using accurate field maps of the focusing and accelerating elements. In t
The accelerator of the European Spallation Source (ESS) will deliver 62.5 mA proton beam of 2.0 GeV onto the target, offering an unprecedented beam power of 5 MW. Since the technical design report (TDR) was published in 2013, work has continued to further optimise the accelerator design. We report on the advancements in lattice design optimisations after the TDR to improve performance and flexibil
In the present paper an iterative time-reversal algorithm, that retrofocuses an acoustic wave field to its controllable part is established. For a fixed temporal support, i.e., transducer excitation time, the algorithm generates an optimal retrofocusing in the least-squares sense. Thus the iterative time-reversal algorithm reduces the temporal support of the excitation from the requirement of neglig
In order to treat highly localized excitations in a solid a simple spherical model has been developed. The Coulomb potential from the nucleus at the site of the excitation is treated exactly, while the potentials from the surrounding sites are turned into pseudoion pontentials. Only the spherical average of these potentials is retained and separate self-consistent calculations for the ground state
Anthropocentrism and disciplinary research have not led to effective solutions to sustainability problems. A shift is required towards biocentric, transdisciplinarity-based solutions, to mitigate rebound effects and unintended, negative effects. In the field of Sustainable Supply Network Design, such shift implies on developing resilient solutions that maximize environmental benefits instead of mi
Background and purpose: Pyruvate dehydrogenase complex deficiency is in up to 90% caused by pathogenic variants in the X-linked PDHA1 gene. We aimed to investigate female relatives of index patients with PDHA1-related disease to (i) describe the prevalence of female PDHA1 carriers, (ii) determine whether they had symptoms and signs, and (iii) delineate the associated phenotype. Methods: In a natio
Allergic contact dermatitis is reported among individuals using continuous glucose monitoring systems and insulin pumps. The aim of this study was to describe contact allergy patterns for allergens in the Swedish baseline series and medical device-related allergens among users. Contact allergy to baseline series allergens and isobornyl acrylate was compared between diabetes patients and dermatitis
In this paper, we explore contemporary regional development in a historic industrial region. Specifically, we unpack the influences of industrial history and culture, built up over several centuries, on contemporary regional development dynamics and issues. In doing so, we draw on an evolutionary perspective within economic geography and perspectives from deindustrialization studies to understand
The construction industry faces many challenges, among which sustainability has become a prominent global goal to assess. In a European context, environmental certifications such as the Nordic Swan Ecolabel are a key incentive for addressing sustainability challenges and aim to reach the 2030 goals (UNFCCC, 2015). However, these incentives and considerations must be integrated with the requirement
iiAbstractThis thesis examines how women living in a women-only asylum shelter in Austria exercise agency in their daily lives amid institutional regulation, legal uncertainty, and prolonged waiting. It explores how residents organise their daily lives, cope with insecurity, and try to maintain a sense of control within institutional settings and social relationships. Agency is not understood as a
Phylogenetic analysis of glycoside hydrolase family 2 including Aspergillus sequences and characterised β-mannosidases from other organisms, clusters putative Aspergillus β-mannosidases in two distinct clades (A and B). Aspergillus species have at least one paralog in each of the two clades. It appears that clade A members are extracellular and clade B members intracellular. Substrate specificity
Abstract in UndeterminedPrevious research on antonyms has shown that some pairings form more felicitous couplings than others. Following up on that research, we conducted two semantic categorization experiments using Event Related Potentials to establish whether there are neurophysiological differences related to levels of antonym canonicity. In Experiment 1, the members of canonical antonym pairs
Stakeholder engagement is viewed as crucial for environmental governance, especially in regard to common-pool resources (CPRs), such as river basins. This study investigates the conceptualisation of stakeholder engagement in Ireland’s third cycle River Basin Management Plan (RBMP). The study examines the underlying presumptions and representations of stakeholder engagement in governmental discours
The increasing urgency of climate change, coupled with the energy crisis and resource scarcity, demands radical and resilient building solutions. Buildings currently consume a significant portion of energy – in the Nordic context, primarily for indoor space conditioning – highlighting their vulnerability to future climate impacts. Free-running buildings, operating without any energy for heating,
Popular Abstract in Swedish Friction Stir Welding eller ”friktionsomrörningssvetsning” är en svetsprocess som kräver ett roterande verktyg som genom friktionsvärme får materialet att mjukna. Verktyget blandar runt det plastiska materialet mekaniskt och skapar en fog av hög kvalité. Processen fungerar utan gas, utan rök, utan tillsatsmaterial och utan att smälta materialet. Alla dessa fördelar skapFriction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. FSW is already widely adopted in several industries but the applications are limited to simple geometries like straight lines or circular welds, mostly in aluminium. The
