I takt med ett mer extremt klimat till följd av global uppvärmning förväntas kusterna världen över bli allt mer utsatta då stormars frekvens och intensitet beräknas öka. För att kustnära infrastruktur och personlig egendom ska kunna stå emot dessa intensifierade belastningar behöver stora delar av världens kustskydd rustas upp. För att tillämpa adekvat dimensionering av dessa faciliteter behöver kThe aim of this masters dissertation is to investigate how problems that includes fluids can be solved numerical through FE-analysis. The problem at hand is to predict the impact force implied by breaking ocean waves on vertical coastal structures. The importance that coastal areas has on human society both from a perspective of economy, infrastructure and recreation are indubitable. Furthermore,

Denna studie undersöker hur medarbetare upplever och skapar samhörighet i en hybrid arbetsmiljö, där arbetsmiljön växlar mellan kontoret och hemmet. Syftet är att fördjupa kunskapen om hur den hybrida arbetsformen påverkar mellanmänskliga relationer och möjligheten att bygga en inkluderande kultur. En kvalitativ ansats med tio semistrukturerade intervjuer genomfördes med medarbetare som arbetar he

Research on assortative mating often focuses on status achievement, particularly education, with status ascription becoming a progressively less important factor throughout the 20th century. Neighborhoods have been considered a kind of status ascription, since they are inherited from parents. Although neighborhoods can be important for preference formation for spousal characteristics and social gr

Solpaneler på taket är numera en vanlig syn, men vart tar elen vägen när solen skiner som mest? I detta examensarbete har det undersökts hur flerbostadshus kan använda egna batterier för att spara pengar, bli mer självförsörjande och samtidigt stötta elsystemet. Svaret är att batterier kan löna sig, om de används smart. När elnätet blir allt mer pressat och produktionen från förnybar energi varierThis thesis examines the economic potential of lithium-ion battery storage systems in multi-family residential buildings in Sweden, focusing on profitability, revenue opportunities, and the factors influencing investment decisions. The increasing share of renewable electricity, combined with the electrification of society, has intensified the need for energy storage solutions capable of balancing

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is primarily known as a respiratory disease. The continued study of the disease has shown that long-term COVID-19 symptoms include persisting effects of the virus on the brain when the infection is over, possibly even leading to neurodegeneration. However, the exact mechanisms of

The PD-AGE international task force underscores the pivotal role that non-human primate (NHP) models play in advancing our understanding of Parkinson's disease (PD) and ageing. Due to their close genetic, anatomical, and behavioural similarity to humans, NHPs uniquely enable translational research to bridge basic science towards clinical application. They are indispensable for modelling the comple

The co-occurrence of α-synuclein (αSyn) and Tau in synucleinopathies and tauopathies suggests a complex interplay between these proteins. Their cross-seeding enhances fibrillization, leading to the formation of diverse amyloid-specific structures enriched with β-sheets, which may influence their biological functions. However, existing tools cannot differentiate structural polymorphs directly in ce

Separating how surface and subsurface species affect catalytic function is a challenging task in heterogeneous catalysis, particularly when deposition and segregation take place at reaction conditions. Here, we report on an operando approach to establish surface/subsurface/function correlations. Using temperature modulations we oscillate carbon deposition and segregation over a Pd catalyst. Cataly

Objectives: While high socioeconomic status (SES) indicators generally protect against mental health issues such as mood disorders in overall populations, evidence suggests that these protective effects might be attenuated for marginalized groups such as immigrants, in comparison to groups who are more socially privileged. This phenomenon is referred to as Marginalization-related Diminished Return

Coherent Diffraction Imaging (CDI) is an experimental technique to image isolated structures by recording the scattered light. The sample density can be recovered from the scattered field through a Fourier Transform operation. However, the phase of the field is lost during the measurement and has to be algorithmically retrieved. Here we present SPRING, an analysis framework tailored to X-ray Free

Background: Magnetic resonance imaging (MRI) is recommended by guidelines to evaluate the severity of brain ischemia after cardiac arrest for functional outcome prediction. However, standardized assessment criteria are lacking. We have developed a semi-quantitative Cardiac Arrest Brain Ischemia (CABI) score to assess the extension of brain ischemia on MRI. Objectives: To evaluate the prognostic pe

Background: Despite its common early onset, little is known about the prevalence and clinical presentation of avoidant restrictive food intake disorder (ARFID) in very young children, hindering early identification and intervention. Differentiating ARFID from normative selective eating is particularly challenging, yet validated parent-reported screening tools are lacking. This study aimed to estim

Introduction: Studies on the association between lipid levels and lipid-lowering treatment and the risk of dementia and/or cognitive decline (CD) have shown conflicting results and are few in individuals with type 2 diabetes (T2D). The aim was to evaluate the relationship of baseline LDL cholesterol levels and statin treatment with the development of dementia/CD in patients with T2D from the Actio

Parids are well-known birds both in Europe and North America. Despite being arboreal foragers of similar size, there is a striking dichotomy in the wintering strategies in the family. Most species are food hoarding specialists that store large amounts of winter food in autumn. A small stable group will then defend a large winter territory in which they store food. From a cognition perspective thes

Background: There has recently been an increased emphasis on patient empowerment and collaboration within their healthcare. However, there is widely a lack of clarity to the concept of empowerment and existing measurement tools lack uniformity, covering diverse domains and related concepts. Objectives: This study aims to conduct a psychometric evaluation of the Swedish version of the Empowerment S

Purpose: To achieve the high sensitivity of digital breast tomosynthesis (DBT), a time-consuming reading is necessary. However, synthetic mammography (SM) images, equivalent to digital mammography (DM), can be generated from DBT images. SM is faster to read and might be sufficient in many cases. We investigate using artificial intelligence (AI) to stratify examinations into reading of either SM or

Purpose: Breast cancer is one of the leading causes of cancer-related deaths among women, and digital mammography plays a key role in screening and early detection. The radiation dose on mammographic exams directly influences image quality and radiologists’ performance. We evaluate the impact of an image restoration pipeline—designed to simulate higher dose acquisitions—on the detectability of mic

Purpose: The purpose is to retrospectively investigate how the addition of prior and concurrent mammograms affects wide-angle digital breast tomosynthesis (DBT) screening false-positive recall rates, malignancy scoring, and recall agreement. Approach: A total of 200 cases were selected from the Malmö Breast Tomosynthesis Screening Trial. They consist of 150 recalled cases [30 true positives (TPs),

Purpose: The purposes are to evaluate the change in mammographic density within individuals across screening rounds using automatic density software, to evaluate whether a change in breast density is associated with a future breast cancer diagnosis, and to provide insight into breast density evolution. Approach: Mammographic breast density was analyzed in women screened in Malmö, Sweden, between 2

The transition to sustainable energy is crucial for modern society, and Reverse Electrodialysis (RED) offers a promising method for harvesting energy from salinity gradients. However, large-scale deployment of RED is constrained by efficiency limitations and the high cost of ion exchange membranes. This study focuses on the development of novel asymmetric cation exchange membranes (CEMs) based on
