This master’s thesis project explores different methods for determining an effective electron-electron interaction strength to model dynamic interactions in the Anderson impurity model, an important model within the field of many-body quantum mechanics. The Anderson model describes an impurity atom which is embedded in a metal, with which in can exchange electrons. In this project, different obser

Idag är Tullkammarkajen en övergångszon från Halmstads innerstad till en aktiv hamn och industri. Två helt olika sammanhang som möts på en plats som saknar sammanhållning med resten av staden. Ett oanvänt mellanrum mellan det som en gång var en viktig position för stadens utveckling, och som nu är en plats som varken knyter an till sin egen historia eller med livet i staden. Ett oplanerat, undervä

This thesis addresses masculine identities and men’s relationship to pro-environmental behavior in the Netherlands. Within this, I assess intergenerational dynamics in the form of father-son interactions as an impacting variable for these views. After conducting semi-structured interviews with father-son duo’s, this thesis finds that the views of these dyads on masculinity and sustainability overl

Effekten av kanalpositioner på prestationsförmågan hos mikrochip byggda för akustofores I detta arbete undersöks hur olika geometriska konfigurationer påverkar effekten av akustofores i mikrochip, med fokus på mikrokanalernas positioner i chippen. Baserat på simuleringar undersöktes primärt två sorters konfigurationer, en "Asymmetrisk kanal" och en "Tvillingkanal". ExperimenteMicroscale acoustofluidics utilizes ultrasound to manipulate microparticles flowing through a microchannel. Using this technique, particles or cells can be e.g. separated, aligned, washed or trapped. It is however an emerging technology that should be further developed in order to maximally capitalize on its potential. One possible improvement is to increase the particle migration velocity by incr

This bachelor thesis has been conducted in collaboration with TeamVate. The project focuses on the development and implementation of an onboarding wizard within TeamVate’s App Studio. The goal is to improve user experience and effectiveness for new users. To reach this goal, we implemented an iterative design process, using Norman’s heuristics, creating both Lo-Fi and Hi-Fi prototypes and conducti

This thesis focuses on the communication of risks in the water sector in Sweden, centring on the 2013 PFAS water contamination scandal in Kallinge, Ronneby. Primarily, the water sector in Sweden lacks qualitative research stemming from the field of sociology, indicating how “wicked water problems” make it difficult to see who holds the responsibility in the sector when a crisis strikes. Herein, it

This master’s thesis was done in collaboration with Qlik with the aim of investigating and comparing the onboarding process between the Business intelligence (BI) tools Qlik Sense and Power BI. BI tools are used to transform raw data into structured information that can be strategically used for decision-making. The study followed an iterative design process, where the first iteration was to ident

Network anomaly detection is an active research area, with numerous solutions that utilize statistical methods, neural networks, and other machine learning methods. Autoencoders, in particular, have shown great performance by learning representations solely from benign traffic, enabling the detection of zero-day attacks. In this thesis, we propose a methodology that uses transfer learning to train

In today’s digital age, there is a growing expectation that digital technologies should help address social and environmental challenges, such as climate change. In response, digital infrastructural platforms increasingly employ gamification as a communication strategy to promote behaviors aligned with the public good. However, when implemented within commercial platforms, such initiatives often s

Bison bonanza: En dag i visentens liv Den europeiska bisonen, visenten (Bison bonasus) är den amerikanska bisonoxens (Bison bison) mindre kända släkting och likväl Europas största vilda däggdjur. Misströsta inte om du helt missat att detta stora oxdjur vandrar i Central- och Östeuropas landskap. Visenten dog nämligen ut i det vilda redan under 1920-talet och har senare blivit återintroducerad medThe European bison (Bison bonasus), is the largest terrestrial mammal in Europe and a possible keystone species. Having previously been extinct in the wild, the European bison faces several severe challenges, such as lack of suitable habitat, habitat fragmentation, isolation of populations, small population sizes and a very limited gene pool. Nonetheless, after a long period of regulated matings a

Påverkar könskromosomerna fitness? Fitness eller reproduktionsframgång påverkas av många olika faktorer. Vilka individer som har högst fitness har betydelse för hur framtida generationer kommer att se ut. Något som skulle kunna påverka fitness är en individs könskromosomer. I denna studie undersöks huruvida den genetiska variationen på könskromosomerna har en effekt på fitness i en population av While the sex-limited sex-chromosome (Y or W) is in general not believed to carry much variation that affects individual fitness, some evidence indicates that the Y sometimes influences male fitness. However, few studies have investigated similar effects of W in females. In this study we use whole genome sequencing data from individuals in a study population of great reed warblers with extensive c

This thesis contributes to the relatively recent call for a climate-labour turn. This turn positions the alliance building between the climate and labour movements as crucial for developing a strong counter-hegemonic movement with the power to push for a just green transition and confront the forces of capitalism. To understand the conditions and strategies necessary to foster such climate-labour

The transition from unicellular to multicellular life remains one of evolution’s biggest mysteries. In this study we introduce symbioses with bacteria as a possible player. We use metagenomic analysis to investigate bacterial communities associated with Volvocine green algae, a model system for multicellularity. We compared bacterial communities of 34 algal species (21 unicellular and 13 multicell

Can Your Genes and Lifestyle Together Shape Your Risk of Parkinson’s Disease? Parkinson’s disease (PD) is one of the most common neurodegenerative disorders worldwide, yet its causes remain only partly understood. While some people inherit rare genetic mutations that directly cause PD, for most individuals, the risk is likely influenced by a complex mix of many common genetic variants and environ

Targeting TB: Scope of Anti-Mycobacterial Compounds Tuberculosis (TB) continues to be one of the leading cause of death until today. The disease has persisted since antiquity and remains a concern despite the advancement in its treatment. The main problem arises from antibiotic resistance developed by Mycobacterium tuberculosis and the complex nature of the bacteria which has developed mechanisms

Blir du en fest för nästa objudna gäst? Under det varma halvåret är det många av oss som ser fram emot att kunna koppla av i skogen eller trädgården. Detta är något som vi i en snar framtid kan behöva göra med extra försiktighet. Till följd av olika faktorer, förväntas många svenskar bli utsatta för ett ökat antal fästingspridda sjukdomar. En av dessa sjukdomar orsakas av en malarialiknande parasDue to climate changes, a large human population, changed lifestyles and travel possibilities, many vector-borne diseases are now on the uprise. The tick-transmitted parasite, Babesia divergens spread by Ixodes ricinus ticks, is one of the emerging pathogens with possible serious outcomes. Most infected people do not obtain any symptoms, but individuals with a compromised immune system or elderly

Fiberbanks have recently received attention as potential greenhouse gas (GHG) sources in Sweden. Fiberbanks are anthropogenically caused fibre-rich sediments in aquatic environments formed by unregulated discharge of fibrous wastewater from historical pulp and paper industries. A majority of fiberbanks show signs of gas ebullition, mainly consisting of methane and carbon dioxide, resulting from an

Hur kan antibiotikabehandling vid tuberkulos bidra till lungskada? Varför drabbas många tuberkulospatienter av långvariga lungskador, trots att infektionen är botad? Ny forskning visar att antibiotikan i sig kan spela en oväntad roll. När bakterierna utsätts för stressen som antibiotikan orsakar, börjar de släppa ifrån sig små kapslar, liknande mikroskopiska paket, som kan trigga immunförsvaret oTuberculosis (TB) affects millions of people annually and remains one of the leading causes of infectious diseases-related deaths in the world. Current anti-TB treatment consists of a prolonged regimen of multiple antibiotics, which effectively eliminates the bacteria when it is not antibiotic resistant. However, large proportions of the TB-treated individuals experience persistent pulmonary dysfu

Orala streptokocker – munhålans gynnare och eventuella fiende Streptokocker är associerade med flera infektionssjukdomar i olika delar av kroppen. En grupp streptokocker (orala streptokocker) återfinns främst i människans munhåla i både friska och sjuka individer. Tidigare studier har visat att orala streptokocker etableras i munhålan redan när vi är barn och finns kvar under hela livet. I den frOral streptococci colonize the oral cavity already during early childhood and establish the foundation for colonization by a multispecies oral microbiota. In the oral cavity, Streptococcus spp. contribute to both health and disease, and can also spread to the blood stream causing bacteremia and systemic diseases such as infectious endocarditis (IE) in certain risk groups. Molecular changes in oral

With an ongoing housing shortage in Swedish cities, challenges such as limited land availability, financing, and the environmental impacts associated with new development prompt us to explore alternative solutions. As architecture is inevitably a form of aesthetics and the idea of transforming and re-adapting our existing structures to deal with these challenges gains traction in the architectur
