This report studies fatigue in welded steel structures of a conveyor belt using the finite element method (FEM) together with hand calculations based on nominal stress. Three methods were used to evaluate stress at critical locations, the nominal stress method, the hot-spot method, and the effective notch stress method. Detailed FEM models were created where weld geometry and critical stress conce
This thesis investigates generational differences in online fashion return behavior in China, focusing on wardrobing and bracketing. An integrated framework combining the Theory of Planned Behavior (TPB) and Generational Cohort Theory (GCT) is tested using a sequential explanatory mixed‑methods design. The quantitative phase surveyed 225 Chinese fashion e‑commerce consumers (Generations X, Y, and
Trifluorättiksyra (TFA), en ultrakortkedjig PFAS, är mycket ihärdig, rörlig i vatten och för närvarande inte uttryckligen reglerad i svensk eller annan europeisk vattenlagstiftning med undantag för Danmark. Denna avhandling undersöker förekomst, trender och potentiell pesticidbildad TFA i svenska grund- och ytvatten samt regulatoriska implikationer på nationell och internationell nivå. Ett datasetTrifluoroacetic acid (TFA), an ultra-short chain PFAS, is highly persistent, mobile in water, and currently not explicitly regulated in Swedish- or other European water legislation apart from in Denmark. This thesis investigates the occurrence, trends, and potential pesticide-derived formation of TFA in Swedish ground- and surface waters along with regulatory implications on a national and interna
This thesis examines how circular fashion services are made practically possible across physical and digital retail touchpoints. While circular retailing is often discussed as a strategic response to fashion’s sustainability problem, the availability of services such as repair, resale, care, and take-back does not automatically lead to participation. Drawing on social practice theory and the mater
Research on video games and sustainability has predominantly focused on game design — examining how serious games, gamification, and narrative design can transmit ecological knowledge or shape sustainability-related behaviour. This design-centred approach, however, treats sustainability as a property to be embedded in the game system and received by players, leaving a theoretical blind spot: it ca
Sensing technologies offer several advantages for industrial tooling. In mechanical processing and manufacturing environments, sensors can be used to monitor process conditions, support predictive maintenance, reduce unnecessary material losses, and improve overall production efficiency. Therefore, as manufacturing systems become more advanced and data-driven, the integration of sensors has become
This study investigates consumer-perceived frictions in cross-channel return processes within Nordic omnichannel retailing and examines how these frictions reflect underlying reverse logistics (RL) integration gaps. While omnichannel research has extensively addressed seamless front-end experiences, the post-purchase return phase remains under-theorized and is often treated as a “black box”, disco
This master’s thesis investigates the system-level and mechanical design of a new service dongle for ASSA ABLOY Entrance Systems AB. The service dongle is a handheld Bluetooth tool used by service technicians worldwide to configure, service, and troubleshoot automatic door operators such as sliding, swing, and revolving doors. Currently, two solutions exist: the Configuration Tool Interface (CTI)
The aim of this study is to investigate if a researchers presence affects participants performing a virtual reality evacuation, and if by removing the researcher, the results better resemble the results produced in a real world experiment. Initially, a study on previous research in human behaviour in fire, the effect of a researcher's presence and Virtual reality experiments was conducted. 54
Cykling är en viktig del av ett hållbart transportsystem. Det bidrar bl.a. till en bättre miljö och förbättrad folkhälsa. Syftet med arbetet är att undersöka vilka faktorer som kännetecknar en bra cykelstad, ur en infrastruktursynpunkt och vilka faktorer som kan leda till ökad cykling. I arbetet intervjuas representanter för kommunerna Lund, Malmö och Helsingborg om vilka infrastrukturella åtgärdeCycling is an important part of a sustainable transport system. It contributes among other things to a better environment and improved public health. The aim of this thesis is to investigate which factors characterize a good cycling city, from an infrastructural point of view, and which factors may lead to increased cycling. In the thesis, representatives of the municipalities of Lund, Malmö and H
The contemporary tourism industry operates within a market-oriented and rationalised logic where risk and uncertainty are primarily perceived as sources of value destruction. While such an approach provides safety and convenience, it simultaneously reduces the spontaneity and unpredictability associated with the unknown. At the same time, the opposite end of the tourism spectrum — unconventional t
Introduction: Dietary macronutrient composition, specifically the intake of meals enriched in carbohydrates, fats, protein or fibre, triggers distinct postprandial metabolic responses but whether these responses vary significantly based on an individual’s glycaemic status: type 1 diabetes (T1D), type 2 diabetes (T2D), or normoglycaemia (ND) remains an open question. Background: Metabolomic and
Understanding the role of conformational entropy in protein-ligand interactions remains a major challenge in rational drug design. In this work Galectin-3C (Gal-3C) complexes with glycomimetic macrocyclic ligands FS435 and FS471 were investigated using NMR spectroscopy. The ligands exhibit similar binding free energies, and calorimetric studies revealed significant enthalpy-entropy compensation. S
This master’s thesis presents the development of an electric cargo vehicle adapted to the urban, infrastructural and socioeconomic conditions of Cochabamba, Bolivia. The project was conducted in collaboration with Eco Delivery, a Bolivian last mile logistics company seeking a sustainable and locally manufacturable transport solution capable of supporting urban delivery operations under demanding c
Mental health problems in Sweden are a growing concern, especially among children and young adults. Child and adolescent psychiatry services (BUP) in Sweden currently have more active cases than in previous years. Consequences of this include an increase in diagnoses of ADHD, a higher risk of suicide among children and young adults, and a growing number of involuntary hospitalisations. The purpose
Denna uppsats undersöker CISG:s tillämplighet på digitala produkter och hur konventionens varubegrepp förhåller sig till EU:s reglering av digitalt innehåll och digitala tjänster. Syftet är att klarlägga om digitala produkter kan omfattas av CISG samt att analysera om konventionens traditionella varubegrepp är förenligt med EU-direktiven på det digitala området. Uppsatsen besvarar två frågeställniThis paper examines the applicability of the CISG to digital products and how the Convention’s concept of goods relates to the EU's regulation of digital content and digital services. The aim is to clarify if digital products may fall within the scope of the CISG and to analyse whether the Convention’s traditional concept of goods is compatible with the EU directives in the digital field. The
This thesis analyzes how South Asian immigrant families in Helsingborg with children utilize, perceive, and sustain car-free mobility in their lives. It reveals that car-free mobility is not merely the absence of car ownership, but a practice shaped by material conditions, users' competencies, and the meanings they attach to different cultural norms and early practice experience in their daily
This thesis examines whether the partially owned parent entity (POPE) rule in the Directive (EU) 2022/2523 (P2D) creates a restriction on the free movement of capital under Article 63 TFEU, and if so, whether that restriction be justified and regarded as proportionate under EU law. The POPE rule forms part of the EU implementation of Pillar Two, which aims to ensure a global minimum level of taxa
Climate change, shifting travel patterns, and the growing popularity of Arctic destinations have driven a rapid increase in tourism in Longyearbyen, Svalbard, over the past few decades. Simultaneously, Longyearbyen is at the end of a transition from a coal-mining community toward a tourism-focused town. While previous research on Svalbard has largely focused on environmental sustainability and gov
