Att kunna skräddarsy biologiskt nedbrytbara stärkelsepartiklar för användning i medicintekniska produkter låter kanske som science fiction, men det håller snabbt på att bli verklighet! Dessa mikroskopiska partiklar tillverkar man av något som de flesta har hemma, potatisstärkelse och kan användas i medicintekniska produkter för att exempelvis blockera blodflödet till tumörer eller upptäcka läckageDegradable starch microspheres (DSMs) are promising biomaterials with expanding medical applications due to their biocompatibility and controlled degradation. DSMs are produced by forming a water-in-oil emulsion using a starch solution, an emulsifier e.g. Starch Acetate Butyrate (SAB) and toluene, followed by crosslinking using a crosslinker, e.g. epichlorohydrin (ECH). The relationship between re

This thesis investigates how business angel investors interpret and evaluate hybrid entrepreneurial teams, startups led by founders who retain salaried employment while launching their ventures. While hybrid entrepreneurship is increasingly common, it challenges traditional heuristics around founder commitment, team scalability, and investability in early-stage finance. Drawing on ten qualitative

Rationale: Patients with obesity hypoventilation syndrome (OHS) have high risk of hospitalization, which might be decreased by home mechanical ventilation (HMV). Objectives: To evaluate annualized hospitalization rate (AHR) and changes in AHR in patients with OHS starting HMV and explore if there were any differences in AHR by starting HMV acutely or electively. Methods: This was a population-base

Background: There are currently no molecular tests to identify individual breast cancers where radiotherapy (RT) offers no benefit. Profile for the Omission of Local Adjuvant Radiotherapy (POLAR) is a 16-gene molecular signature developed to identify low-risk cancers where RT will not further reduce recurrence rates. Methods: An individual participant data meta-analysis was performed in 623 patien

Two different diets able to induce dietary hyperammonaemia (a methionine–choline-deficient (MCD) diet and a methionine-deficient diet enriched with ammonium acetate (MAD + 20% ammonium acetate)) were tested in a rat model. The diets were shown to have different modes of action, inducing significant hyperammonaemia (HA) and growth retardation in the rats, with different metabolic consequences. The

The molecular surface compositions of aerosols can differ considerably from their bulk counterparts, an aspect often overlooked in climate models. This oversight can potentially affect our understanding of the complex interplay between composition, optical characteristics, and their influence on cloud formation and properties. A substantial portion of aerosol mass often includes organic compounds,

This thesis investigates how startups in Tier 2 European cities achieve sustainable growth by engaging with their local entrepreneurial ecosystems. While prior research has largely focused on major capital cities, this study aims to understand how emerging urban canters with less mature infrastructures can still support high-growth entrepreneurial activity. A qualitative research design was employ

Access to financing for women entrepreneurs plays a fundamental role in the creation and development of their startups. Our study found that women founders, specifically within tech startups, face barriers and challenges when searching for and navigating different types of financing options. There is a gap in the literature regarding gender disparities in entrepreneurial finance and limitations of

This thesis explores how business angels’ (BA’s) human- and financial capital contribute to the early-stage development of start-ups. While previous literature has extensively discussed BAs' financial roles, the combined effect of both capital types, particularly in relation to relational trust, remains underexplored. Addressing this gap, the study applies a qualitative approach, interviewing

For decades, entrepreneurs faced the same trade-off: either pursue cost leadership and grow fast through various scaling strategies or pursue differentiation strategies by emphasizing personalization of their services to customers. Nevertheless, the situation has changed when new technologies such as artificial intelligence, rising computing power, digitization of firms, or cloud services started

Despite generative Artificial Intelligence’s (AI) explosive growth in popularity and record of biased outputs, little attention has been paid to the technology’s potential to shape perceptions around sustainability. This analysis investigates which perceptions about climate change causes, impacts and solutions are visually naturalised or marginalised by three text-to-image AI models: GPT‑4o, Ideog

Although conflict, climate change and natural hazards frequently coincide, consequently affecting human security, disaster risk reduction and climate change adaptation as well as security risk mitigation are often treated separately in programme implementation. This, however, increases the risk in overlooking the opportunity to address root causes caused and exacerbated by climate change, natural

I takt med att skogsbränder blir vanligare och allvarligare till följd av klimatförändringarnas effekter, ökar behovet av effektiv riskhantering och förståelse för de bakomliggande faktorerna till uppkomst och spridning av skogsbränder. Denna rapport angriper riskhantering av skogsbränder ur två perspektiv – kvantitativt och kvalitativt. I huvudsak presenteras spatio-temporala modeller för intensiAs wildfires are becoming more frequent and severe due to the effects of climate change, there is a need for effective risk management and understanding of the drivers behind wildfire ignition and spread. This thesis tackles wildfire risk management from two angles- quantitatively and qualitatively. Primarily it presents spatio-temporal models of the wildfire ignition intensity and the size of bur

Svårare torrperioder leder till högre koldioxidutsläpp från jorden När det regnar på jord som varit utsatt för torka orsakar det total panik bland jordens mikroorganismer. En fotbollsplan kan då släppa ut lika mycket koldioxid på en vecka som en bil gör på tre månader. Effekten har varit känd sedan 60-talet, men tidigare forskning har inte testat vad som händer om det växer gräs i jorden under toBased on current climate data both drought intensity and frequency is expected to increase. Soil microbes react in a variety of ways to drought-imposed stresses, with only a fraction surviving until wetter conditions return. As drought ends and rain returns, these microbial communities respond with an associated pulse in soil CO2-emissions called the Birch effect. Understanding soil microbial resp

Dela plats med tången på stranden Usch vad det stinker! Men det kanske är värt det ändå? Alla känner vi till hur tång ansamlas på badstränderna, och under den varma sommarsolen börjar tången ruttna och lukten sprider sig genom byn. Men kan det vara värt att lida lite för den biologiska mångfalden? En enkät skickades ut till södra Sveriges kustkommuner för att ta reda på hur de arbetar med tång pThe threat against biodiversity on beaches is significant in combination with the erosion pressing on our coastlines. At the same time beaches provide paramount cultural and recreational value and are expected to be attractive and accessible for beach visitors. This study explores macroalgae and the conflict between using the beach as a habitat to promote biodiversity while also promoting recreati

In this master’s thesis I aim to produce knowledge concerning the perceived expertise and cognitive authority of generative AI models, specifically in regard to health, politics and the environment. This problem is important to investigate in order to better understand how people interact with synthetic information, both as a reliable source and as an example of mis- or disinformation. Furthermore

Idag är ett av de största hoten mot vår miljö den snabba förlusten av biologisk mångfald. Ungefär 86 % av de hotade arterna i världen påverkas negativt av jordbrukets markanvändning, det motsvarar mellan 24 000 och 28 000 arter. Det här gör jordbruket till en nyckelfaktor i kampen för att bevara planetens arter. Att bevara planetära arter är inte enbart viktigt från ett miljöperspektiv utan även fGlobal biodiversity is heavily damaged by human interventions. There are multiple drivers for human-caused biodiversity loss; however, land use linked to agricultural production is the leading one. In response to this major threat, the interest in and importance of assessing the potential biodiversity impacts, particularly those related to land use, have grown significantly. Especially within fram
