The reemergence of China as a global Great Power raises multiple questions regarding how China will exert its influence on the international arena. Arguably the most important feature of China’s current foreign policy, the Belt and Road Initiative (BRI) can be considered a manifestation of China’s contemporary ascendancy. The establishment of the BRI hinges on an extensive diplomatic effort by Chi
This thesis seeks to investigate the role of the Sustainable Development Goals (SDGs), the Paris Agreement, and the Swedish Climate Act in the transition to net-zero in energy intensive industries, with a focus on the steel sector. Several empirical studies have previously been done on both national and international policies and how they influence low-carbon transitions and technological innovati
Newspapers and media have always played a critical role in society and have come to shape the way we reflect and perceive news and societal issues. Journalists are conveyer of a message and act as a moderator to shape and set the agenda for the public opinion and the public discourse. This research paper examines the media portrayal of refugees from Ukraine and Syria through pictures. These confli
This study aimed to engineer and characterize a series of Amelogenin-ELP fusion proteins to explore their potential as biomaterials with enhanced properties. Eleven constructs (176-186) were designed and expressed in E. coli BL21(DE3) cells, with successful purification confirmed by SDS-PAGE. Dynamic Light Scattering (DLS) revealed that constructs 181, 185, and 186 formed nanospheres similar to fu
In all living organisms, proteins which transport water and other small solutes across the membrane exist and are known as aquaporins. Aquaporins consist out of four monomers, forming a homo-tetramer with a substrate conducting channel in each monomer. Aquaporins can be regulated by either gating or trafficking, which allows the cell to control the permeability of the membrane. Aquaporin 5 is one
Chili peppers are known for causing a pungent sensation due to the presence of capsaicinoid compounds in their fruits. In the Capsicum genus, capsaicin biosynthesis relies on the condensation of vanillylamine and the fatty acid 8-methyl-6-nonenoic acid, a reaction catalyzed by an acyltransferase. Currently, capsaicin has become a highly relevant molecule to the pharmaceutical industry due to its a
Återvinning av polymerer är nödvändig för hållbar livsföring och miljöförvaltning, och mekanisk återvinning har fördelen av mycket lägre energi- och materialförbruking jämfört med kemisk och fysisk återvinning. Ett framträdande problem med mekanisk återvinning är emellertid förkortningen av polymerkedjor som sker under deras livstid. Tekniken Reactive Recycling™ av Nexam Chemical innebär att återvRecycling of polymers is necessary for sustainable living and environmental stewardship, and mechanical recycling has the advantage of much lower energy and material demand compared to chemical and physical recycling. A prominent problem, however, with mechanical recycling is the shortening of polymer chains that occurs during their lifetime. The technology Reactive Recycling™ by Nexam Chemical in
Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. By introducing an enzyme-based sunscreen for daily facial use these damages may be reduced while also providing exfoliation and hydration
In the hardware development space, field programmable gate arrays (FPGAs) are in a unique position as a result of their in-field re-programmability. In contrast to the traditional design process of integrated circuits, FPGAs allow iterative de- velopment workflows closely resembling software development’s sprint-based pro- totyping. For this to work, efficient workflows for verification are key. V
Age-associated B cells (ABCs) are a novel subtype of B cells that accumulate with ageing, during infection, and in the progression of autoimmune diseases. Still, their exact phenotype and effector functions remain unknown. In this thesis, we aimed to provide an immunological characterisation of human ABC subsets by phenotyping them before and after in vitro stimulation and evaluating the alteratio
The peacekeeping mission in the Democratic Republic of Congo (DRC) is one of the most extensive and complex missions ever carried out by the United Nations. Amongst the operational adaptation, one challenge has remained consistent; the crisis of Sexual Exploitation and Abuse (SEA) committed by UN peacekeepers against the very civilians they are mandated to protect. This essay aims to explain how t
The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. I will first simulate the influence, that the other planets have on
Optical DNA mapping is a technique for obtaining fast DNA sequence dependent barcodes by observing the stained DNA with a microscope, while it is held stretched inside a nanochannel. Noise plays an important role in optical maps and can significantly change the features in a barcode. One way to reduce random noise is to time average many time frame measurements. This method is efficient but requir
Abstract This thesis work was performed at RUAG Space AB, Göteborg, Sweden. The aim of this thesis is to test the performance boundaries of SiGe based heterojunction bipolar transistor in designing a low noise amplifier meant for GNSS applications. After careful consideration of different alternatives for active components in SiGe HBT process, BFY640-04 from Infineon was selected as the active com
In this master´s thesis I seek to explore the concept of restorative justice, an ideological approach to justice which aims to repair the harm caused by crime through means of communication, cooperation, participation and restoration. By involving all parties affected by crime, restorative justice seeks to address crime through empowering victims, increasing community cohesion and making offenders
The automobiles of today are getting more fuel efficient in order to meet future emission standards. It is also important to have more fuel efficient engines than the competitors. The consequence is that engine development is intensified and more ideas needs to be tested thoroughly. One of the ideas at Volvo cars is a tumble flap. The tumble flap is controlled to close a predefined part of the int
This paper empirically examines the relationship between fuel prices and patenting activity in environment-friendly technologies in the auto industry across the OECD countries for the period 1994-2011. Overall, the results suggest that tax-inclusive fuel price affects innovative activity in environment-friendly technologies. More specifically, the analysis shows that the technologies aiming to red
Thermoelectricity is the physical principle of converting heat energy directly into electrical energy. Devices based on this principle so far fall short on efficiency but future thermoelectric devices based on QDs can have very high efficiency. Before QDs can be used in actual devices their behavior must the studied to a further extent. This work theoretically explores how a QD in a single electro
Model-based design is in many ways seen as a potential instrument in process industries due to the close link between the process and the model. In Växjö, the process industry of Lantmännen Reppe AB produces syrup. The syrup goes through an evaporation process in order to raise the sugar concentration. If the concentration gets to high the syrup turns solid, which can make the process a bit tricky
