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
This thesis examines how transnational mobility shapes the relationship between the sense of national belonging, European affiliation, and openness towards “others” among Polish students who have studied abroad. Based on 308 survey responses, it explores how living and studying away from one’s home country influences self-perception and impacts intergroup attitudes, applying Social Identity Theo
The growing number of offshore wind farms being constructed in the North Sea raises important questions about their potential ecological impact on marine communities. Monitoring these effects requires tools that can accurately describe biodiversity, not just in terms of species presence, but also their relative abundance. Environmental DNA analysis is a promising approach for this purpose, but the
Denna uppsats fördjupar sig i Louis Spohr och hans Första Konsert för Klarinett och Orkester, Op. 26, med början i en översikt över kompositörens liv och hans verk. Analysen kommer att ge en bättre förståelse för innebörden och egenskaperna hos kompositörens skrivande under hans musikaliska karriär. Uppsatsen utforskar också hur hans konsert framförs på ett sätt som ligger närmare hur kompositörenThis thesis delves into Louis Spohr and his First Concerto for Clarinet and Orchestra, Op. 26, starting with an overview of the composer's life and his work. The analysis will provide a better understanding of the meaning and characteristics of this composer's writing during his musical career. The thesis also explores the performance of his concerto that is closer to the composer’s origin
Objectives: Pregnancy can influence immune control of Mycobacterium tuberculosis infection (MtbI). We recently reported an association between MtbI and pregnancy complications, particularly severe preeclampsia, in a registry-based cohort of women originating in tuberculosis-endemic countries screened for MtbI in Swedish antenatal care, implying a potential role of MtbI for the development of preec
Aim: The aim of this study was to investigate the annual prevalence and characteristics of Paediatric Feeding Disorder (PFD) in Västerbotten county, Sweden, during the years 2012–2022. Methods: In this retrospective study, medical records of patients attending paediatric clinics with possible feeding problems were identified by applying pre-defined diagnostic and procedure codes. Diagnostic criter
Swedish stakeholders have expressed their opinions in an interview study on the three most necessary, existing, or non-existing, policy and regulatory measures to accelerate the transition to emission-free electric freight transports with Heavy Duty Trucks (HDTs) in regional operation in Sweden. The study has been carried out as part of a Swedish system demonstration project, REEL, that includes m
We know little about the odds of growing old in the later Middle Ages because reconstructions of the longevity and life expectancy of populations require baptismal, marriage, and death registers, which only gradually appear after 1500. The few earlier reconstructions that are available concern males; the female experience of ageing is mostly based on small samples of elite women who lived in the M
Throughout the past years, the Orthodox world has seen numerous political and theological confrontations. New borders have been shaped by churches and states. This only increased in light of the Russian-backed conflict in Ukraine from 2014 and onwards, which has led to new theological lines of thinking, geopolitical confrontations, and an acute need for diplomatic handling of crisis. At the centre
This letter proposes a novel wideband, single-layer monopolar antenna with high selectivity and enhanced pattern stability across the operating band. Building upon a conventional circular patch antenna, the rejection levels of the upper and lower sidebands are carefully analyzed, designed, and optimized to achieve the desired performance. To further improve performance, a shorting-via-loaded ring
Assessing cross-taxon congruence is vital for effective forest conservation, because different taxonomic groups may respond inconsistently to key habitat variables such as stand age. We examined six taxonomic groups—insects, arachnids, springtails, epiphytic lichens, bryophytes, and vascular plants—across 25 Swedish oak stands ranging from 19 to 165 years old to determine whether species richness
This book considers the potential solutions that the sharing economy offers to tackle the increasing challenges of urbanisation and sustainability facing cities. It emphasises the need for robust policies to ensure that the sharing economy supports urban sustainability and resilience by promoting more efficient and circular use of urban resources through practices like car-sharing, accommodation r
An LSTM-based deep learning model, as well as a Lasso and linear regression model, were implemented to try and predict citation counts based on the abstracts. In an attempt to try and model the relationship between the citation count and the abstracts, specifically in the field of chemistry. A comparison between the Lasso model and the deep learning model was done, in order to weigh the interpreta
Shrub range expansion, also known as shrubification, across arctic and subarctic ecosystems is expected to increase with climate change, with implications for vegetation structure, biodiversity, and soil carbon dynamics. Previous research has found a shrubification-induced decrease in organic matter stocks from tundra to forest in the organic horizon, prompting further investigation into whether t
Modebranschens tillväxt online har förändrat konsumenternas köpvanor, men har även bidragit till en ökning av deras returer. Detta har i sin tur medfört påtagliga miljömässiga konsekvenser för samhället. Konsumenter uppskattar företagens milda returpolicy, men detta har bidragit till en problematik där de beställer fler kläder än vad de faktiskt behöver. Allt fler företag har börjat implementera r
In times of rising inflation, global unrest and shifting societal values, much of the public and academic focus has been on how economically vulnerable groups adapt their consumption. However, less attention has been paid to high-income earners who are often assumed to remain unaffected by economic fluctuations. This thesis investigates how high-income individuals in Sweden navigate their everyday
Purpose: The Extremely Preterm Infants in Sweden Study (EXPRESS) followed a national cohort of extremely preterm born (EPT, i.e. <27 weeks) children until 12 years of age. This study aimed to investigate the longitudinal development of visual acuity (VA) in children born EPT, explore the predictive value of early visual assessments, and evaluate risk factors for visual impairment at the age of 12
