A search for the leptonic charge asymmetry (Acℓ) of top-quark-antiquark pair production in association with a W boson (tt¯ W) is presented. The search is performed using final states with exactly three charged light leptons (electrons or muons) and is based on s = 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider at CERN during the years 2015–2018,

The Siusi/Seis section has been measured for the δ13C signature across the Permian-Triassic Boundary (PTB) in high resolution on magnetostratigraphic samples from Scholger et al. (2000), enabling an exact correlation with magnetostratigraphic data. We show that the base of the short normal polarity magnetozone that has been reported from the evento-stratigraphic boundary correlates with a distinct

Tensor-valued encoding in diffusion MRI allows probing of microscopic anisotropy in tissue, however, time-dependent diffusion (TDD) can bias results unless b-tensors are carefully tuned to account for TDD. We propose two novel strategies for tuning b-tensors to enable accurate measurements without interference from TDD due to restricted diffusion. The first strategy involves identifying encoding t

Phylogenies are central to many disciplines in biology. While disciplines such as systematics are focused on phylogenetic hypotheses themselves, other disciplines depend on robust and well-supported phylogenies in order to put biological data into evolutionary context through phylogenetic comparative studies. Examples of such fields are macroevolutionary research e.g. studying the evolution of a f

Access to outdoor leisure activities is central to supporting active and healthy ageing. To address the lack of research on services supporting continued engagement, this study examines how public, voluntary and private sectors provide outdoor recreation services for older adults. This study uses a qualitative research design to draw on interviews, a workshop, and field observations conducted in a

BACKGROUND: Peptic gastroduodenal stenosis is a rare but disabling condition causing gastric outlet obstruction. This study aimed to evaluate endoscopic balloon dilation in terms of treatment effectiveness, durability, and identify potential early predictors of unsatisfactory outcomes.METHODS: We conducted a retrospective cohort study of patients who underwent endoscopic balloon dilation for sympt

In the face of climate change, today’s young people need to balance the challenges of being active and maintaining mental health. This study investigated climate resilience, meaning patterns of climate engagement and mental health among adolescents. Using latent profile analysis, we identified three profiles in a sample of N=603 Swedish adolescents: climate-resilient (17%, active and not impaired)

Osteoarthritis (OA) and rheumatoid arthritis (RA) are the two most common rheumatic diseases worldwide, causing pain and disability. Both conditions are highly heterogeneous, and their onset occurs insidiously with non-specific symptoms, so they are not always distinguishable from other arthritis during the initial stages. This makes early diagnosis difficult and resource-demanding in clinical env

The purpose of this paper is to identify significant factors of influence for the co-existence and team climate within working groups, and to examine their impact on the psychosocial work environment within a group. Team climate and interaction affect every individual in a group. The manager, however, is the one formally accountable for the psychosocial climate in a working group, which is the rea

The purpose of this essay was to examine what Ungbo in Kalmar has meant for the adolescent from their point of view and to examine the social workers opinions of Ungbo. My questions were: What expectations did the adolescent and the social workers have on Ungbo? How has these expectations been fulfilled? What expectations does the social workers think the adolescents has on Ungbo? How is the impa

Populärvetenskaplig sammanfattning: Våtmarkers utvecklingshistoria kan rekonstrueras genom att deras lagerföljd undersöks. Genom att studera de sediment, växtdelar och pollen som en våtmark är uppbyggd av kan man dra slutsatser om hur den bildats och hur dess utbredning varierat på grund av klimatförändringar och/eller mänsklig påverkan. Rekonstruktioner av förändringar i våtmarkers utbredning bidWetlands are of uttermost biological importance as they function as natural purifiers, absorb nitrogen, and contribute to the landscape biodiversity. In a long term, the history and change, in area- and volume extent, of wetlands reflect climate trends through time. This master’s thesis is an attempt to develop a methodology that in a simple and robust way reconstructs wetland changes using sedime

This essay is about reading among patients in hospital. The aim of the essay is to find out what part reading and the library play for patients in hospital. An additional aim is to find out in what ways the collaboration between hospital librarians and hospital staff could be developed. The starting-point of the problem is one main question: What part does reading play for the patient during the s

The aim of this paper is to expand the debate on globalization and its consequences from a theoretical perspective emphasizing social processes of exclusion and inclusion. I explore these social processes in dialogue with the Spanish social movement for the rights of irregular immigrants. The paper also aims to explore new forms of resistance in the context of globalization. "The declinist t

Uppsatsen behandlar 3:s etablering på den svenska marknaden för mobila teletjänster. För att kunna analysera detta har jag kombinerat empiri med vald teori. Den insamlade primärdatan består av telefonintervjuer med beslutsfattande personer på såväl 3 som andra konkurrerande företag och institutioner. Teoriavsnittet är uppdelat i två huvuddelar - pris- och spelteori, då marknaden karaktäriseras av

Through trading with countries that have a relative aboundant supply of labor, Sweden changes it's effective supply of labor, in a Factor Content perspective. This essay does two Factor Content analyses, one for year 1995 and one for 2000. The first comparison of these analyses shows that Sweden exports about 27 600 labor-years more year 2000 than 1995. However, since Factor Content analysis a

BACKGROUND: One of the critical challenges with capitation payment to primary care providers is ensuring that the fixed payments are equitable and adjusted for expected care needs. Patients of lower socioeconomic status (SES) generally have higher health care need. Sweden developed a Care Needs Index, which is used in the capitation payments to primary care providers to account for patient SES.OBJ
