Vi människor har ej nyttjat de naturresurser som vår planet har försett oss med på ett ansvarsfullt sätt. Just nu producerar och konsumerar vi i en takt som vår planet inte klarar av. För att bryta detta mönster krävs en omställning. För produktutvecklare innebär detta ett ansvar att utveckla hållbara produkter. En utmaning som kan lösas genom att designa produkter i miljövänliga material som kan In this thesis, initiated by Axis Communications, the material choice of a folded horn loudspeaker was investigated. The main goal of the project was to determine if it was possible to reduce the costs and environmental impact of the product by means of optimizing the material, while maintaining or improving its performance. The three main parameters which were analyzed were the acoustic performan

Mitt kandidatarbete handlar om att representera den elektromagnetiska fälttensorn med matematiska objekt som kallas spinorer, bland annat genom att undersöka hur de transformeras när man byter referenssystem. Den här texten ska försöka förklara vad något av det där betyder, och sedan varför det är intressant för teoretiska fysiker. Vi börjar med transformationer. I våran vardag är vi vana med attThis thesis presents a way of representing electric and magnetic fields directly as linear combinations of products of components of Weyl spinors, without using a four-potential. First it is shown that when Lorentz transforming the spinors, these fields transform according to the tensor transformation of the electromagnetic fields. Then, by explicitly expressing the spinors in terms of a four-mome

This thesis investigates what drives people to use credit-style Buy Now, Pay Later (BNPL) services, focusing on Klarna users in Sweden. Drawing on behavioral economics, it tests whether having a present-biased time preference (a strong preference for immediate rewards) can predict a person’s use of Klarna’s “Pay Later” and “Installments” features. To explore this, a cross-sectional survey (N =100)

This thesis examines the role of visual media in conveying the Gallic founding myth and constructing national identity in nineteenth-century France. Positioned at the interdisciplinary intersection of nationalism studies and memory research, it investigates how visual representations embed the Gallic founding narrative – despite its association with military defeat – into France’s collective memor

The study was conducted as a qualitative study including a literature review, document study, and an interview study. Contractual tender documents were analyzed in the document study. In the interview study, both contractors and public procu

Bakgrund: Antalet människor som på olika sätt påverkas av naturkatastrofer, krig eller konflikter ökar. Dessa katastrofsituationer medför att de som drabbas får inskränkt möjlighet att engagera sig i viktiga och meningsfulla aktiviteter. Arbetsterapeuter har kompetens om hur person, miljö och aktivitet samspelar och kan bidra till arbetet i samband med katastrofsituationer och med katastrofdrabbadBackground: The number of people affected by natural disasters, war, or conflicts is increasing. These disaster situations limit the ability of those affected to engage in important and meaningful activities. Occupational therapists have expertise in how person, environment, and activity interact and can contribute to efforts related to disaster situations and people affected by them. Aim: The aim

Per- and polyfluoroalkyl substances (PFAS) are persistent synthetic chemicals widely used in consumer and industrial products. Increasing evidence of their adverse health effects has intensified the need to understand their impact on human immune function. This study assessed PFAS toxicity using a human dendritic cell model by focusing on gene expression and surface marker modulation, as well as a

The Arctic has increasingly emerged as a geopolitical horizon shaped by environmental, security and economic transformations. As sea ice melts and military and commercial interests materialise, questions arise about how the region is discursively constructed by various stakeholders. With the Arctic Council in flux, alternative forums have gained significance as sites for dialogue and public diplom

This thesis is looking at Sweden’s implementation and priorities of the 2030 Agneda and specifically SDG 3 pertaining to health and wellbeing. It explores how national and international dynamics influence Sweden’s commitment to SDG 3, by examining shifts in political leadership and the developments within the global governance system. Placing Sweden within the broader context of global health gove

The European Union’s sustainability reporting framework, which includes the CSRD and the CSDDD, is widely regarded as a logical progression toward achieving the 2050 climate goals. The EU has faced criticism regarding the sustainability reporting directives, primarily due to concerns over the EU’s global competitiveness and the readiness of undertakings to comply. Consequently, there have been inc

Antimicrobial resistance (AMR) and natural hazards and associated disasters both pose significant global threats, with potential for exacerbating intersections. Despite AMR’s growing international priority, the nexus of AMR and hazards/disasters remains underexplored. This thesis aims to provide a comprehensive overview of the nexus to inform future perspectives and highlight further investigation

This thesis provides a comparative analysis on sustainability chapters in free trade agreements (FTA) from the EU and Australia. It then evaluates the implication this comparison has in light of EU-Australia FTA negotiations. In addition to this, the text utilises a funnel approach by examining broader concepts in order to help answer the research question. This includes the definition of free tra

This thesis examines the extent to which Indigenous and local communities are able to meaningfully participate in the governance of the Oxapampa-Ashaninka-Yanesha Biosphere Reserve (BIOAY). Peru is a mega-diverse country and has eight Biosphere Reserves, which operate through a multilevel governance model that prioritizes Indigenous and local participation for successful sustainable development ou

Climate change, changing weather patterns, and coastal erosion pose significant risks to the Hebridean isles, which are home to a unique habitat and a cultural landscape known as ‘’machair’. The machair is a coastal landform located exclusively in Scotland, with its majority of existence restricted to the western shore of the Outer Hebrides. This unique habitat, shaped by northern Atlantic winds a

3D Gaussian Splatting (3DGS) has emerged as the latest breakthrough in 3D reconstruction since it can provide photorealistic 3D reconstruction with real-time rendering. Despite its increasing popularity, it lacks an accessible and clear end-to-end workflow, and the use for it in interactive and immersive applications remains largely unexplored. Furthermore, with the constant development of new 3DG

This thesis performs a critical evaluation of the original Cost-Benefit Analysis (CBA) of the Lund tramway project, focusing on its adherence to the then-current Swedish national appraisal guidelines (ASEK 5) and the accuracy of its demand forecasts. An updated demand forecast and monetary valuation of time savings are constructed and compared to the original CBA projections by using empirical pas

This master’s thesis investigates the potential of applying transformation principles from the fashion industry to architectural design, specifically, how fundamental textile techniques such as seams, cuts, and slits can convert flat, two-dimensional surfaces into complex three-dimensional forms. Through a series of material experiments with these traditional methods, slits and cuts were identifie

Agricultural workers are on the frontlines of climate change, experiencing firsthand the effects of heatwaves, extreme weather, floods, and droughts on their health, safety, and livelihoods. However, their capacity to address these risks is often restricted by vulnerability factors such as workplace precarity, socioeconomic and immigration status, poor access to health services, and cultural and l

Denna uppsats undersöker volontärarbete inom Rädda Barnens barnverksamhet vid ett svenskt asylboende som en levd, situerad och moraliskt komplex praktik. Genom en kvalitativ metodologi, baserad på semistrukturerade intervjuer och deltagande observation, analyseras hur volontärer själva förstår sitt engagemang i relation till emotionella, etiska och politiska dimensioner av samtida migrationskontex

Industrial areas have played a vital role in shaping cities, serving as economic centers and employment places for decades. However, with economic trends drifting and other technological advancements lead to the constant change of industrial areas. They mostly became abandoned or underutilized due to this. These transitions created plenty of environmental, social and economic challenges including
