The rising levels of greenhouse gas emissions, especially of carbon dioxide, imposes a significant threat to the world, requiring new decarbonisation technologies. This thesis explores integrating a Power to X system with an existing biogas plant utilizing waste from salmon fishery. Three pathways for upgrading biogas to methanol or methane were investigated: (P1) direct carbon dioxide to methanol

This study explores how successful livestreamers use strategic communication during TikTok Livestream Shopping, to create influence on viewers' purchase behavior. Livestream Shopping is a well-established phenomenon in Asia, but it remains under-researched in the Western context, particularly from the livestreamer’s perspective. By analyzing the communication of three successful Western livest
ABSTRACT Phygital and gameful interventions are increasingly used by Destination Management Organisations (DMOs) to manage visitor movement, interpretation, and access in fragile heritage destinations. Yet their contribution to sustainable and resilient destination development remains unclear, particularly when digital tools do not translate smoothly into situated visitor experience. Focusing on D
This thesis investigates the wear behaviour of advanced cutting tools during the milling of fully pearlitic CGI 450 and ferritic-pearlitic SSF CGI 350. The hard CGI 450 primarily induced mechanical abrasive wear, whereas the highly ductile, ferrite-rich SSF CGI 350 triggered adhesive wear and built-up edge formation. EDS analysis confirmed the dynamic formation of a protective Mg-Si-O layer, which
The World Heritage Site Venice and its Lagoon faces major challenges to its conservation, mainly those of mass tourism and climate change. This thesis examines how Venice is represented and managed as a World Heritage Site in official reports by Unesco and Italy, with a particular focus on conservation, tourism and sustainability. The study is conducted through a qualitative content analysis of Un
This thesis examines recent years’ unresolved conflicts on the state’s right to regulate and the protection of foreign investors in ‘climate blind’ energy agreements, such as the Energy Charter Treaty. One of the primary disputes among them is the vague language of indirect expropriation in traditional International Investment Agreements (IIAs), which mostly favours investor protection. While IIAs
This thesis investigates whether a variational autoencoder (VAE) can be trained directly on raw, ir- regularly sampled option quotes rather than on pre-interpolated volatility surfaces. A Raw Set VAE is proposed, combining a Set Transformer encoder with a pointwise decoder to process unordered, variable-length sets of SPX option contracts without requiring prior grid construction. To isolate the c
Gängkriminalitet är ett ämne som framställts av flertalet svenska nyhetsartiklar under de senaste åren. Denna uppsats syftar till att undersöka hur unga kvinnor delaktiga i gängkriminalitet framställs i svenska nyhetsartiklar mellan 2023 och 2025. Den syftar även till att undersöka hur deras framställningar kan förstås i relation till samhälleliga föreställningar om kvinnlig kriminalitet. Valet gr
From both a legal and business perspective, it is important for credit institutes to accurately assess the risk of default for potential borrowers. This is traditionally done using statistical methods, such as logistic regression or decision trees, utilising sociodemographic and credit history information.This thesis investigates whether a bureau score, provided by a credit bureau, should be incor
Revisorn i Sverige idag innehar en viktig uppgift. Detta då han eller hon har som huvuduppgift att granska och kontrollera att ett bolags förvaltning och rapportering är korrekt. Utöver detta har revisorn enligt 9 kap. 42–44 §§ aktiebolagslagen en skyldighet att vidta åtgärder om denne, vid sin granskning av bolaget, skulle finna misstankar om att ett brott har begåtts. Syftet med denna uppsats haThe auditor in Sweden today has an important task. This is because his or her main responsibility is to review and ensure that a company´s management and reports are accurate. In addition to this, the auditor has an obligation to act due to Chapter 9, Sections 42-44 the Swedish Companies Act if, during the audit of the company, he or she discovers suspicions that a crime has been committed within
Bakgrund: Barn-och ungdomar med psykisk ohälsa har ofta svårigheter att reglera sensoriska intryck i sin vardag, vilket påverkar målgruppens möjlighet att vara engagerad i aktiviteter i det dagliga livet. För att möta dessa svårigheter använder arbetsterapeuter inom psykiatrin i en internationell kontext sk. sensorisk modulering som intervention. Det är dock oklart hur det ser ut i svensk kontext,Background: Children and adolescent with mental illness often have difficulties regulating sensory inputs in their daily life, which affects their ability to engage in daily activities. To address these difficulties, occupational therapists in an international context, use so called sensory modulation interventions in psychiatry. However, it is unclear what this looks like in the Swedish context,
High temperature corrosion presents a challenge both in predicting material loss over time and in cleaning and reusing the material after oxidation cycles. This thesis investigates the oxidation behavior and descaling of different austenitic stainless steels exposed to a range of temperatures in an oxygen-rich environment. The first part of the project focused on developing a descaling method. Tw
Events in recent years have prompted a resurgence in Sweden’s civil defence planning, with national authorities increasingly focusing on securing the supply of critical goods and services such as food. Yet the societal functions that together uphold Sweden’s food system—primary production, manufacturing, distribution, and public meal service—are embedded in complex supply chains shaped by both dom
Parallellt med det svenska energisystemets elektrifiering så sker även en snabb utveckling av AI-verktyg. Dessa redskap medför helt nya möjligheter att ta olika former av datadrivna beslut vilket kan revolutionera delar av energisektorn. Samtidigt så är de inte helt oproblematiska, utan deras effekter måste analyseras grundligt för att de ska kunna leva upp till sin potential, samtidigt som effektThe Swedish energy system is currently in a transition, aiming for carbon neutrality. At the same time, AI technology is developing in a fast manner. These tools come with entirely new possibilities to make data driven decisions, which can revolutionize parts of the energy sector. At the same time, they come with their own challenges. Therefore, their effects must be thoroughly examined if they ar
Furfural, a renewable platform chemical derived from hemi cellulosic fraction of the lignocellulosic biomass, is a promising precursor for the sustainable production of 2,5- furandicarboxylic acid (FDCA), an important bio-based alternative to terephthalic acid. In this study, we utilized the oxidative capacity of Gluconobacter oxydans to oxidize furfural to 2-furoic acid and employed the UbiD-UbiX
This study examines how the Bird’s Nest in Beijing has been reused after the Olympics and how it is presented as a model of sustainable urban development. Using an Urban Political Ecology (UPE) perspective, it explores how sustainability is defined, implemented, and experienced. The research is based on policy analysis, critical discourse analysis, 20 interviews, and field observation. The finding
Denna studie undersöker hur kvinno-, tjej- och transjourer organiserar och upprätthåller sina verksamheter i relation till statliga bidragssystem, administrativa krav och föreställningar om värde. Studien bygger på kvalitativa semistrukturerade intervjuer med åtta personer verksamma inom olika jourorganisationer i Sverige. Materialet analyserades genom tematisk analys med utgångspunkt i teorier om
Carbon accounting has become an important part of sustainability governance, as organisations are increasingly expected to report and justify their climate impacts. However, emissions figures are not neutral technical outputs. They are shaped by methodological choices, boundaries, assumptions, data infrastructures, and professional judgement. This is especially relevant for municipalities, where c
Infrastructure barriers and high costs of alternative sustainable fuels constrain the global logistics sector's transition to decarbonization. This research investigates how logistics providers establish institutional trust in the 'Book and Claim' service, where the environmental benefits of sustainable fuels are spatially decoupled from the physical transport of goods. Because corpora
