Konstruktiv länkning, studentaktivitet och föreläsningar är tre grundstenar i högre utbildning. Men föreläsningen som undervisningsform har kritiserats: ”Det finns gott om högskolepedagogisk litteratur som förklarar varför föreläsningen är olämplig för att stimulera lärande. Ändå fortsätter vi föreläsa”, skriver Andreas Håkansson (2017, s. 40) i en artikel som trots allt landar i att denna undervi
The metalorganic chemical vapor deposition (MOCVD) dynamics of beta-gallium oxide (β-Ga2O3) growth using trimethylgallium (TMGa) and oxygen as precursors were investigated through both theoretical thermodynamic analysis and experimental validation in a horizontal low-pressure hot-wall reactor. Thermodynamic analysis revealed that high-purity β-Ga2O3 can be grown through the complete combustion of
Gamified virtual reality (VR) environments are increasingly used to enhance engagement and learning, yet most designs still adopt a one-size-fits-all approach that overlooks motivational diversity. The HEXAD framework, which classifies users into six player types, provides a promising lens for addressing this gap, but its predictive validity in immersive VR remains contested. This study investigat
This study explores a novel approach to utilizing waste biomass for syngas production, with the potential for carbon sequestration. An integrated biomass conversion process combining pyrolysis, CO2 reforming, and MILD combustion is proposed. In the proposed system, the bio-oil obtained from pyrolysis can be used in a reforming step, converting it into syngas with a suitable H2/CO ratio for chemica
Adaptive reuse, the conversion of buildings for new functions, is gaining prominence for its cost-saving and environmental benefits. However, prior research primarily focuses on preserving the building envelope, often overlooking building services such as ventilation, which affect occupant well-being, costs, and environmental performance. This study explores a novel adaptive reuse approach by reus
Climate neutrality of cities has emerged as a critical goal for sustainable urban development. This is typified by the mission in the European Union (EU) to achieve 100 climate neutral and smart cities by 2030. The idea of carbon or climate neutrality holds diverse interpretations. This paper investigates the dominant socio-technical imaginary for urban climate neutrality within the context of the
Self-harm, including nonsuicidal self-injury and suicide attempts, is common among youth, associated with elevated psychopathology, suicide risk, and increased demand for clinical services. Despite advances in understanding and treatment, few interventions have demonstrated efficacy in randomized controlled trials (RCTs), which are considered the gold standard for evaluating treatment effects by r
Diabetes is a growing global problem, with hundreds of millions of people living with the disease worldwide. Diabetes can be divided into two major subtypes, autoimmune type 1 diabetes (T1D), and type 2 diabetes (T2D), which has stronger causal links in obesity, lifestyle, and age. Although immunity and inflammation are clearly defined in T1D, it is also understood that inflammation has a role in
This thesis investigates how the integration of post-combustion carbon capture (PCC) systems would affect combined heat and power (CHP) plant performance, using DWSIM, an open- source process simulation tool. A case study on a CHP plant in southern Sweden was conducted, with models simulated for both baseline and CCS-integrated operation. DWSIM proved accurate within a relative error of under 3 %
Botswana’s reputation as a beacon of fiscal prudence in resource-rich economies faces new challenges. Yet recent pressures – rising debt, declining surpluses, and fiscal volatility – raise questions about the long-term sustainability of this model. This thesis examines how Botswana’s fiscal capacity has shaped its ability to manage natural resource wealth between 1990 and 2022. Drawing on a compos
As the demand for sustainable and efficient energy systems continues to grow, integrated energy solutions have sparked interest in materials that combine multiple functionalities within a single structure. Rather than serving a single purpose, such materials could store energy, catalyse chemical reactions, and even exhibit optical changes, enabling novel applications in smart devices and material
This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic
Far beyond its innocence, children and child welfare initiatives have emerged as powerful symbols in Indonesian political campaigns. This research focuses on Joko Widodo and Prabowo Subianto, showing how their use of initiatives like Smart Card and Free Lunch Program projected legitimacy and garnered votes during the 2014, 2019, and 2024 elections. It uses two main methods: reflexive thematic anal
This study examines how AI for minors is framed by AI companies and constructed in public discourse in China and the United States. Using Rhetorical Arena Theory and framing theory, the study analyses corporate communication from four AI platforms (ChatGPT, Gemini, Grok, and Doubao) together with public discourse materials, including mainstream media, NGO reports, and online commentary. Reflexive
Reframing authoritarian legality through multi‑level, interdisciplinary doctoral researchSOCIAL’s aims coalesce around a pressing global need: to understand why legal transplants and governance reforms often falter in authoritarian contexts—and how law actually operates within them. The project articulates its ambitions through three interconnected goals, underpinned by a cohesive doctoral trainin

It is frequently observed that the local relative abundances of aquatic microbial taxa are correlated with their average relative abundance at the regional scale, which results in the composition of different communities being more similar than expected by chance or invariant. The degree to which communities within a region match the regional average community is variable and likely depends on sev
The design and fabrication of a home-made thin-layer electrochemical flow cell are reported. The performance and electrochemical characteristics of thin-layer cells are evaluated in terms of flow rate and channel thickness. The adaptability of the flow cell for amperometric and electrochemiluminescence measurements is demonstrated. Also, a flow injection method comprising electrochemical generatio
Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos
It has been suggested that organic farming may benefit farmland biodiversity more in landscapes that have lost a significant part of its former landscape heterogeneity. We tested this hypothesis by comparing bird species richness and abundance during the breeding season in organic and conventional farms, matched to eliminate all differences not directly linked to the farming practice, situated in
Popular Abstract in Swedish Förbränning av fossila bränslen som bensin, kol, olja och naturgas orsakar att koldioxid ackumuleras i atmosfären, vilket är en av orsakerna till global uppvärmning. Transportsektorn står för största delen av Sveriges användning av bensin och olja. Oljan är importerad från andra länder, som gör oss väldigt beroende av omvärlden. Ett av de mest lovande alternativa bränslTransportation fuels from renewable resources such as ethanol are one of the alternatives to ensure energy security and decrease the net emission of carbon dioxide. First-generation ethanol production from sugar- and starch-based raw materials (1G) is today well established in many countries, and the focus of research has thus shifted to the development and demonstration of the production of secon
