The purpose of this study is two-fold: first to validate previous findings, that showed that the central atom in (bacterio)chlorophyll changes ligand coordination number upon being cooled at a certain rate (in certain solvents), and to resolve the Qx and Qy bands from the total absorption spectrum. We studied bacteriochlorophyll A (BChl A), bacteriochlorophyll C (BChl C), and chlorophyll A (Chl A)
Demands for socialization understood as the collective, democratically governed ownership of essential goods, are growing louder in Germany’s energy sector. This thesis critically examines how German labor unions and environmental NGOs articulate the concept of socialization within the energy sector, using Antonio Gramsci’s cultural hegemony and Nancy Fraser’s progressive neoliberalism as theoreti
With ongoing strains and disparities in the healthcare system, Generative AI applications are increasingly viewed as promising tools to alleviate pressure in this sector. Trust is seen as a critical enabler for the integration of GenAI tools. However, this area remains largely unexplored, with limited research examining user-perceived trust. This study addresses this gap by adopting a qualitative
In an increasingly dynamic and complex business environment, organizations must develop the capacity to effectively adapt to continuous change to remain competitive. Many organizations are facing a significant disconnection between realizing the need for change and being able to successfully implement it, underlining the need for structured change management approaches in driving change initiative
Social isolation and loneliness among older adults are growing public health concerns. Although information and communication technologies (ICT) are increasingly promoted to foster social connectedness, how older adults perceive and adopt these technologies remains underexplored. This study applies the Unified Theory of Acceptance and Use of Technology (UTAUT) to examine ICT engagement among older
The transition to sustainable energy systems is one of the defining challenges of the 21st century in Europe, especially in the context of the ambitious climate goals of the European Union. This thesis investigates the differences in strategic approaches towards the fundamental energy transition between the Nordic countries and the Central European countries. The focus of this thesis is specifical
Varför kriminaliseras och stigmatiseras vissa droger, när andra förblir både socialt och juridiskt accepterade, trots liknande skadeverkningar? Denna fråga utgör en central utgångspunkt i den svenska drogdebatten, där alkohol är en laglig substans med stark kulturell acceptans, medan narkotika juridiskt definieras som förbjudna ämnen med skadliga eller beroendeframkallande effekter. Syftet med den
Bakgrund: På HVB (Hem för Vård eller Boende) hem bor individer i varierande åldrar med problematik såsom missbruk och psykiatriska diagnoser, där brist på struktur och meningsfull vardag ofta utgör ett hinder för utveckling. Tidigare forskning visar att aktiviteter är avgörande för att främja hälsa, delaktighet samt välmående, men det saknas forskning om hur placerade personer själva upplever akti
Denna studie syftar till att undersöka hur Nonviolent Communication (NVC) kan bidra till en sundare arbetsmiljö samt att identifiera faktorer som påverkar möjligheten till en lyckad implementering. Studien baseras på åtta semistrukturerade intervjuer med individer som aktivt använder sig av NVC på arbetsplatsen. Datan analyserades med tematisk analys utifrån ett kritisk-realistiskt perspektiv. ResThis study aims to explore how Nonviolent Communication (NVC) can contribute to a healthier work environment, and to identify factors that influence the possibilities of a successful implementation. The study is based on eight semi structured interviews involving individuals who actively apply NVC at their place of work. The data was thematically analysed from a critical-realistic perspective. The
Background: Growing corporate awareness of environmental and social impacts, coupled with initiatives like the Science-Based Targets initiative (SBTi), is driving companies to address greenhouse gas emissions, particularly indirect Scope 3 emissions which often constitute the largest share of their carbon footprint. For ASSA ABLOY, Scope 3 emissions represent 99% of its total footprint, with purch
This research aims to study the relationship between population, income and public assistance outcomes in Puerto Rico after Hurricane Maria. This is done through an event style approach using zip code level data and a fixed effects estimation strategy. Precise hurricane damage are used to evaluate variations of the effects of damage types. A positive association is found between income per capita
Detta examensarbete undersöker och jämför lönsamheten för två olika metoder för underhållsarbeten på järnväg i form av spårbyten utifrån ekonomiska och tidsmässiga aspekter. Dessa metoder är den traditionella traktormetoden och det avancerade spårbyteståget. Syftet med arbetet är att undersöka användningen av spårbyteståg och traditionella metoder vid underhållsarbeten på bana i Sverige samt när d
This study evaluated the efficacy of reduced-temperature pasteurization in preserving the nutritional, sensory, and microbial integrity of two fruit juice products: a standard orange juice and a probiotic mango juice enriched with Lactiplantibacillus plantarum 299v, conducted at Österlenmejeriet AB in Lunnarp, a subsidiary of Danone. Laboratory-scale thermal treatments were applied at temperatures
Purpose: The purpose of this study is to analyze the sentiment towards masstige collaborations on social media, and to see if contextual factors, such as duration of the collaboration or the sentiment towards the partnering brands prior to the collaboration, are related to a change in said sentiment. Theoretical Perspective: This study draws on existing literature on the masstige topic to define
This study investigates deep learning approaches for automated land use classification from high-resolution remote sensing imagery, comparing Convolutional Neural Network (CNN) and Vision Transformer (ViT) architectures. Eight semantic segmentation models were evaluated on the HRSCD dataset containing 291 aerial image pairs (0.5m resolution) with four land use classes: building, agricultural, fore
The current fast paced technological innovation demands major attention from businesses across the globe. AI dominates discussions one day, and the next it is all about quantum computing. To remain competitive companies must constantly be on the watch for trend shifts and technological advancements. In order to stay ahead of the curve companies can utilize technology scouting to monitor the techno
Anthropogenic coastal and marine activities, like dredging of the seabed, can affect ecosystems through increased turbidity by raising the level of suspended sediment concentrations (SSC). To accurately validate spilled sediment, simulations of background concentrations are essential as both spilled and natural sediment is included in measurements. This thesis aims to improve the representation of
This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin
The goal of this research is to investigate how the use of provocative place branding, by companies, influences audience engagement with national identity, from a sensemaking perspective. The study specifically investigates how audiences, in the case of residents of Denmark, make sense of provocative content and how it influences their sense of place and national identity. The answered research qu
