Introduction: Dried blood spot sampling is an alternative way to conventional blood sampling that could potentially be a large benefit for certain patient groups. A good example is the transplanted patient group treated with the immunosuppressants everolimus and sirolimus. Background: The challenge is to develop a reliable quantification method based on this relatively novel sampling technique.

The search for greener ways of producing plastic has been a very popular field for the last few years. One avenue of research focuses on separating plastic production from the fossil fuel industry by finding bio-based alternatives. This is the case of the research conducted by our collaborators at Biotechnology who are trying to use Escherichia coli to produce 1,4-butanediol, a precursor to many p

Fragmentation from the extraction of bone marrow for consumption is a common phenomenon in archaeological assemblages, because of the high fat content of bone marrow, it was an important source of sustenance in prehistory. From the perspective of marrow fracturing, analysis of these fragmented refuse materials gives insight into the general strategies for harvesting bone marrow. The fragmentation

Shifting away from long-standing optimistic evaluations of team building activities, this thesis provides insights into the nuanced and contested roles of team building activities in the context of Chinese workplaces. By integrating the perspectives of the communicative constitution of organizations (CCO) with sensemaking theory, the study focuses on how employees make sense of team building activ

Halvledare och transistorer är en av de mest banbrytande upptäckterna i modern tid, och är själva hjärtat i modern teknik. Halvledare är material som kan leda elektrisk ström, men bara under vissa förhållanden, vilket gör dem ovärderliga för elektroniska komponenter som transistorer, dioder och solceller. Från våra mobiltelefoner och datorer till kraftsystem och fordon, så finns komponenter gjordaThis thesis explores edge termination techniques to optimize the breakdown voltage of vertical GaN FinFETs with a 5 µm drift layer using Sentaurus TCAD simulations. Effective edge termination is crucial for managing electric field distribution and mitigating field crowding, which can otherwise cause premature breakdown. Several methods, including field plates, beveled edges, and ion implantation,

Gummiindustrin står inför stora utmaningar när det gäller återvinning. Globalt sett är deponering av gummi, särskilt bildäck, ett allvarligt problem då dessa material, tack vare sin robusta kemiska struktur, inte bryts ner i naturen. Idag är förbränning den främsta metoden för att hantera gummiavfall. Denna process frigör den stora mängden energi som är lagrad i gummits molekylära struktur och bidThe recycling of cured silicone elastomers addresses three critical challenges: reducing the energy-intensive production and demand for raw materials and improving waste management for synthetic and natural rubber materials. A significant obstacle is the strong crosslinks within the polymer network, which give these materials their unique properties but also make them non-biodegradable and difficu
