"There is a crack in everything. That's how light gets in." With two simple sentences the famous poet Leonard Cohen describes his perception on how light interacts with matter. This thesis work will try to give a more precise and detailed description of the interaction between light and nano-materials that maybe is going to lose some of the magic that poetry has but this will be com
För att undersöka hur bins ögon och struktur ser ut behöver man först göra förberedningar så att bihuvudet man undersöker ser snyggt ut. För att åstadkomma detta kan man i princip säga att de enda kunskaperna som krävs är att veta hur man klipper papper, klistrar och limmar fast föremål på önskat ställe som i detta fall är på toppen av en liten nål. Flertalet bihuvuden (94 st)har alltså fästs på nThe complexity and importance of the eyes of a rather simple organism, the bee, is apparent when looking at the adaptation to their environment. The so called compound eyes consists of multiple facets, each having their own point of view and combined results in a larger image. For being able to study the magnificent eyes on a bee's head, there have been in recent studies an increase by X-ray t
Diagnostic reference levels are the main and the most effective tools of optimization of the radiation protection of patients from medical exposure. Diagnostic reference levels should be established based on theresults of dedicated dose surveys, allowing evaluating typical patient dose distributions in a selected dose quantity for the selected X-ray examinations. The aim of the current study was t
The ability to apply highly controlled electric fields within microfluidic devices is valuable as a basis for preparative and analytical processes. A challenge encountered in the context of such approaches in conductive media, including aqueous buffers, is the generation of electrolysis products at the electrode/liquid interface which can lead to contamination, perturb fluid flows and generally in

The main goal of this project was to investigate how the thermal stability of two different types of polyhydroxyalkanoates; poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) were affected when washing them with acid solution. Initially, four different acids were used: citric acid, hydrochloric acid, formic acid and acetic acid. Citric acid gave the best results for both biop
This paper highlights the complexity and ambiguity regarding the phenomenon of so called honour-related violence and oppression and explores how these matters are taken into consideration in the field of social work. In order to explore this field of study we used qualitative research as the method of inquiry. Semi-structured interviews were conducted with six female social workers working with pe
Despite the issue of greywater management gaining more importance around the world, espe-cially in developing countries, it still remains a challenge in non-sewered areas of South Afri-ca. For a semi-arid country, reusing greywater on a household level has great potential as an alternative water source if done properly. On a household level, the popular repurposing of greywater is for irrigation
Syftet med detta examensarbete var att ta fram en enkel och lättförståelig hygienutbildning för nyanställda på Arla i Götene, Västergötland. På detta mejeri tillverkar Arla smör och ost och är även distribution plats för Arlas övriga produkter. När livsmedelverket genomförde en revision av livsmedelsindustrin framkom det avsevärda brister i dokumentation av uppställda rutiner. Även om hygienutbildThis aim of the thesis work was develop a simple and easily understandable hygiene education for new employees at Arla in Götene, Västergötland. At this dairy, Arla produces butter and cheese and is also the place for distribution of Arla's other products. When the national food agency conducted a review of the food industry, the significant shortcomings in the documentation of established pro
Objektiv bildkvalitetsbedömning (IQA) är viktig för att utvärdera och säkerställa bilders kvalitet. Traditionella bedömningar utförda av människor, även om de är pålitliga, är opraktiska på grund av höga kostnader, långsamma processer och subjektiva variationer. Detta arbete syftar till att lösa dessa problem genom att utveckla en test- och kvalitetsbänk för Bertin Exensors “dual-head” kamerahuvudObjective Image Quality Assessment (IQA) is crucial for evaluating and ensuring the fidelity of images. Traditional human-based evaluations, although reliable, are impractical due to their cost and slow pace, combined with subjective inconsistencies. This thesis aims to address these issues by developing a test and quality bench for Bertin Exensor's dual-head camera, integrating both infrared
Givet ett harmoniskt vektorfält u på en begränsad domän kallar vi den mängd där u träder in i domänen för inträdesrand och den mängd där u lämnar domänen utträdesrand. I den första delen av detta examensarbete ställer vi frågan om det är möjligt att ha inre stagnationspunkter och sammanhängande inträdes- och utträdesrand. Svaret i två dimensioner är ‘nej’ för en domän som är homeomorf till skivan.Given a harmonic vector field u on a bounded domain we call the set on which u enters the domain entrant boundary and the set on which u exits the domain emergent boundary. In the first part of this thesis we ask the question of whether it is possible to have interior stagnation points and connected entrant and emergent boundaries. The answer in two dimensions for a domain homeomorphic to a disc i
E-waste is one of the fastest growing waste streams today and considered a significant developmental challenge with less than 30% of e-waste being formally recycled. High-income countries are at an increasing rate exporting their hazardous waste onto low- and middle-income countries, creating additional pressure, exacerbating health risks, and degrading local environments in countries with less ca
This study explores how older adults in Copenhagen experience the transition into empty-nest life within the broader context of Denmark’s welfare system and cultural values. Using a mixed-method approach, including surveys, in-depth interviews, home visits and walk-along observations, the study investigates perceptions of the respondents concerning how Denmark’s strong welfare system, community en
Uganda faces various challenges related to compliance, including tax evasion, regulatory non- compliance, and violations of legal standards, laws, policies and regulations among others. These issues undermine the government's ability to collect revenue, provide public services, and maintain law and order. Enhancing compliance is not only a matter of enforcing penalties but also involves creati
The recent push for decarbonization in the maritime sector presents an opportunity for ports to strengthen their position as energy hubs. This work studies the existing energy flows in the Port of Trelleborg, one of Europe's biggest roll-on, roll-off ports, and proposes some energy-related development strategies. The current energy flows directly concerning the port are for the most part elect
In the early stage of a drug discovery project, there is a need for efficient methods that can analyse peptides in short time. This includes methods that confirm the peptide’s identity and estimates its relative purity in an efficient and reliable way. The aim was to create a workflow for peptide characterization for AstraZeneca’s in-house peptides that was applicable for a high-throughput analysi
