Poxviruses are large, double-stranded DNA viruses that replicate directly in the cytoplasm of the host eukaryotic cell. During assembly of viral particle progeny, viral membrane precursors derived from the endoplasmic reticulum, exhibit stabilised open ends inside intermediate structures called crescents. The process of viral membrane biogenesis during poxvirus assembly remains poorly understood.
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
As geopolitical instability and war increasingly affect entrepreneurial ecosystems, there remains a critical gap in understanding how ventures sustain operations under conditions of active, prolonged conflict. While existing resilience literature often focuses on temporary crises or post-conflict recovery, this study explores how tech small and medium-sized enterprises (SMEs) in Ukraine build oper
Bakgrund: Diskussionen om klimathotet, som är ett resultat av människans aktivitet, har pågått under årtionde. Inom arbetsterapeutisk teori innefattar konceptet ecopation att människan bör göra medvetna ekoetiska val som främjar hållbarhet på individuell, samhällelig och planetär nivå. För studenter i Sverige förespråkas från universitetshåll ett hållbart och ekoetiskt vardagsliv. Dock saknas studBackground: The discourse on the climate threat, as a result of human occupations, has persisted for decades. Within occupational therapy theory, the concept of ecopation encompasses the idea that individuals should make conscious eco-ethical choices that promote sustainability on individual, societal and planetary levels. Swedish universities advocate for a sustainable and eco-ethical everyday li
The high-temperature oxidation of stainless-steel parts poses significant problems in power generation, chemical processing, and heat exchanger industries. Stainless steel grades such as austenitic AISI 316L, 310S, and ferritic 430 commonly used in industries undergo carving of oxide scales which diminishes spatial quality, increases corrosion, and reduces thermal conductivity. This thesis focuses
Health inequality and unequal access to health care remain significant problems in Sweden. Migrants report enjoying a lower level of health, both in general and specifically in regard to sexual and reproductive health and rights (SRHR), as recognised by the Swedish Public Health Agency in their 2020 National Strategy. As a subgroup, asylum seekers find themselves at a particularly high vulnerabili
The Haber-Bosch process is a widely used method for industrial nitrogen fixation, converting nitrogen gas (N₂) into ammonia (NH₃). However, it is energy-intensive, requiring high temperatures and pressures. Biological nitrogen fixation (BNF) may offer a sustainable alternative, utilizing bacteria like Azotobacter vinelandii to convert nitrogen gas into ammonia. Co-culture systems combining A. vine
Industriella revolutionen är en av de största stegen människan tagit i sin utveckling som art. Idag, ungefär två sekel senare kantas samhället med problem såsom föroreningar och hög energiförbrukning. En central aktör i denna utveckling är den kemiska industrin – en vital sektor som, särskilt inom områden som läkemedelsutveckling, har expanderat kraftigt under 1900-talet. I EU under 2020, producerChemical waste from industrial processes poses a significant environmental challenge, often resulting from inefficient synthetic routes that involve excess reagents and ineffective methods. The principles of atom and step economy have become central to modern synthetic strategies, aiming to minimize waste and maximize molecular efficiency. In this context, photo-redox catalysis has emerged as a co
This thesis investigates the ecological and urban regeneration of the Svisloch River in Minsk, focusing on its central urban segment. Historically a natural watercourse and public axis, the Svisloch has undergone a significant transformation into a technically regulated water body, reflecting the city's changing priorities as a result of Soviet-era infrastructure development and contemporary u
This research has been conducted to measure the brake particle emission from freight trains drag braking operation. It only focuses on mechanical brakes by using two different brake pad material one is sintered, and another one is composite, in combination with grey cast iron brake disc. All the materials have been collected from real time braking operations from Green cargo. This research is an e
Assessing credit risk for European utility companies is difficult due to the limited number of defaults and differences in data availability between firms. This thesis develops a hybrid framework to estimate one-year Probability of Default for a portfolio of European utilities, combining a market-based structural model for publicly traded companies with a financial ratio-based scoring model for pr
Problem: The Milky Way disk consists of two distinct components, the thin and thick disk, each with unique kinematical, elemental, and age-related properties. Among all the properties considered, age stands out as the only one that does not exhibit significant overlap, thereby offering clearer separation between the populations. Stellar ages, determined through isochrone fitting, are reliable main
Extremophilic bacteria, like Rhodothermus marinus, hold promising potential to be used as non-model cell factories for the production of various metabolites, such as carotenoids or exopolysaccharides, due to their inherent adaptability to extreme environmental conditions. This study explores the production, isolation, and characterisation of carotenoids from an engineered R. marinus strain termed
This thesis examines the causes and effects of the 1762 prohibition introduced by the Swedish diet against the collection of seabird eggs. The study lies at the intersection of environmental, political, animal, and hunting history, focusing on environmental regulations concerning huntable species imposed by political authorities. Previous research has largely accepted the prohibition as a given, w
The fundamental way to optimize hedging transactions is to improve trading technology. This thesis uses AI to process the fat-tail part of financial data and optimizes the classic hedge error loss problem. Fat-tail data indicates large price changes, contains a lot of information, and has a large degree of data dispersion, which is suitable for AI processing. Investors will only trade when they se
Denna studien syftar till att undersöka om könsidentitet och stereotyper är relaterade till hur svenska medborgare med B-körkort bedömer sin egen kompetens inom bil- och trafikkunskaper, samt om dessa variabler ger upphov till överkonfidens inom det valda ämnet. Tidigare forskning visar att det existerar föreställningar och stereotyper om att män är bättre bilförare än kvinnor, men också att dettaThis study aims to examine whether gender identity and stereotypes has an impact on how Swedish citizens with class B driving licence self-assess their competence regarding driving knowledge, as well as if these variables contribute to overconfidence within the chosen subject. Earlier research has found that stereotypes, that men have better driving knowledge than women, exists. This further leads
The way resources are extracted, consumed and handled after use puts pressure on the environment. In order to slow down the flow of resources, circularity has emerged as a solution by the EU through the Circular Economy Action Plan. To make the transition to a circular economy possible, companies have to adjust their business models accordingly and Product-as-a-Service is one of many circular busi
