The irresponsible use and premature disposal of office furniture, influenced by current linear business models causes a high environmental impact and depletion of natural resources. Innovative and circular business models can be applied in order to close, narrow and slow down resource loops. Implementation of circular business models nonetheless encounters a number of challenges. The main objectiv
PURPOSE. Epithelial maturation is essential for the specificity and functionality of retinal pigment epithelial (RPE) cell models. This study investigates how different maturation conditions shape RPE characteristics and cellular complement biology in two commonly used in vitro models: ARPE-19 and induced pluripotent stem cell–derived RPE (iPSC-RPE). METHODS. ARPE-19 and iPSC-RPE cells were cultur
Metastable nonradiative centers (supertraps) are significant energy loss channels in perovskite optoelectronic devices. In their active state, supertraps induce substantial energy loss through nonradiative recombination of free charge carriers. Transitions between active (energy loss) and passive (no energy loss) states result in photoluminescence (PL) blinking on timescales from milliseconds to s
Understanding and managing charge carrier recombination dynamics is crucial for optimizing the performance of metal halide perovskite optoelectronic devices. In this work, we introduce a machine learning-assisted intensity-modulated two-photon photoluminescence microscopy approach for quantitatively mapping recombination processes in MAPbBr3 perovskite microcrystalline films at micrometer-scale re
2,4-Dinitrophenol (DNP) is a potent mitochondrial uncoupler briefly marketed in the 1930s as a weight-reducing agent before being banned by the FDA after reports of severe toxicity. Since the early 2000s, DNP has reemerged as an illicit "fat-burner", causing characteristic metabolic disturbances with a high risk of fatal outcome. We describe two Swedish cases of DNP poisoning: one fatal after suic
Invasive alien species cause harm to native flora and fauna, and can ultimately via biotic interactions and alterations of the abiotic conditions change entire ecosystems. They have therefore during the last decades gotten more attention and are now recognised as one of the major threats to biodiversity worldwide. When invasive plants establish in an area, one concern is that their presence can af
Introduction Trauma accounts for nearly 10% of the global burden of disease. Several trauma life support programmes aim to improve trauma outcomes. There is no evidence from controlled trials to show the effect of these programmes on patient outcomes. We describe the protocol of a pilot study that aims to assess the feasibility of conducting a cluster randomised controlled trial comparing advanced
Studiens syfte har varit att studera polisens reformarbete i den ungefärliga tidsperioden som sträcker sig de 100-åren mellan 1920-2020 med utgångspunkt från nationaliseringsreformen 1965. De frågeställningar som ligger till grund för att ta sig an materialet och som denna undersökning vill besvara är, hur uppstod och vad var syftet med polisens två stora reformer? Hur blev utfallet av dessa? Och,The purpose of this study have been to research the swedish police authority reforms in the approximate timespan of the 100-years that passed between 1920-2020. The starting point of the study has been set to the nationalisation-reform in 1965 although further inquiry into the years before was needed for context. The research issues at hand are, how did the nationalisation come to be? And what was
To gain increased understanding of how long-term societal trends affect the southern Swedish electric distribution systems, a risk and vulnerability assessment was conducted with the help of literature analysis, interview and Matlab simulations. A representative distribution network was created to mimic Helsingborgs network, owned by Öresundskraft. A comprehensive literature study and interview wi
The scope of this master thesis is the scientific publishing in Social Science at Lund University. By combining bibliometric studies and qualitative interviews, this thesis investigates how scholars in Social Sciences at Lund University respond to performance- based evaluation. The aim is to explore how research practices, publication patterns and disciplinary norms are affected by the increased r
This thesis explores two interrelated issues when it comes to traditional alcohol in Tanzania and its day-to-day activities: identity formation and local economic life. Given the fact that drinking traditional alcohol in Africa is an intrinsic part of social life, it becomes an object in the articulation of diversity, coexistence, and preservation of identity. The study presents women as nodes thr
The Brundtland report envisioned three sustainable dimensions for development: economic growth, ecological balance, and social inclusion with the aim to incorporate these dimensions into local, national, and global plans for sustainable development. In recent years, discussions about our society’s competitiveness and whether the three dimensions of sustainable development include all aspects of ou
This essay has investigated immigrants and Swedes with foreign background’s perception of cultural heritage as it has been specified by UNESCO. The approach to focus on this particular sample population was born out of the realisation that the EU, nationalist parties and far - right extremists all point to a common her itage. What has not been studied however is the effect of immigration on nation
Research Question: How do Swedish coworking firms internationalise, and what are the Key Success Factors allowing for a successful internationalisation? Purpose: This study investigates what drives international expansion for Swedish coworking firms. It also sees why these internationalisation projects were or were not successful. By identifying the key factors behind the projects, the study aims
Climate change is intensifying globally, leading to rising temperatures. The Arctic being a vulnerable and extreme environment faces an enhanced warming effect, referred to as the Arctic amplification. In this rapidly changing environment, high amounts of carbon (1,460 – 1,600 Pg C) are stored in permafrost. This is four times the amount of carbon being emitted by humans in modern times. Increasin
When particles are dispersed in a microfluidic device, its resonant frequencies can be used to manipulate their positions at will. This practice, called acoustophoresis, has been shown to successfully control multiple particles simultaneously with a single vibrating actuator, which is a low-cost and contactless alternative to existing particle manipulation methods, and whose applications include i
Stormfloder betraktas som ett stort hot mot ekosystem och infrastruktur längs kuster, och hotet ökar på grund av det nuvarande föränderliga klimatet, med alltmer frekventa översvämningshändelser, erosion och sedimentomlagring. I detta sammanhang blir insatser för att identifiera spår av stormfloder i geologiska arkiv allt viktigare för att förstå effekterna av sådana händelser på miljön. Denna stuStorm-surges are considered a major coastal threat to ecosystems and infrastructure in the current changing climate, with increasingly frequent flooding events, erosion and sediment redistribution. In this context, efforts to identify traces of storm-surges in the geological record are becoming increasingly important to understand the impacts of such events on the environment. This project investi
The number and complexity of modern software systems have increased substantially since their inception. This unrelenting growth is making manual code review more difficult year by year, and the gap between the amount of code and security verification creates a critical need for automated tools that can assist developers in detecting vulnerabilities. A possible solution to this is large language m
This thesis explores how large manufacturing companies in the Benelux region make sense of climate resilience and what they perceive as its key elements. Although ‘corporate climate resilience’ has gained increasing attention in academic and practitioner-oriented literature, the concept is characterised by ambiguity and fragmentation, resulting in inconsistent corporate interpretations and practic
Sundaland, a subcontinent situated in the Indo-Malay Archipelago, is characterized by a dynamic climatic, geological, and geographical history and a correspondingly diverse biota. The distribution of this biota follows complex biogeographical patterns, with high levels of local endemism and frequent instances of hidden diversity—greater genetic differentiation than expected based on phenotype. Bio
