In recent years, concerns about the damaging environmental effects of conventional plastics have surged, by which biobased and biodegradable plastics have been promoted as a favour-able alternative. Agricultural side streams have been proposed as a potential feedstock for extracting components for new compostable polymers. The present study investigates agri-cultural side streams for raw material
What happens when open, informal spaces disappear – and specifically, what happens when these spaces disappear in a city that used to be full of them? My project is rooted in two things. The first is the highly debated ”Amazon Tower” in Friedrichshain, and the polarized urban conditions around it. The second is my love for Berlin. Berlin has always been a city in flux. However, the latest round
ODIN (Optical and Diffraction Imaging with Neutrons) is a general purpose imaging in- strument under construction at the European Spallation Source (ESS). The instrument will provide the scientific community with a wide array of neutron imaging techniques, including neutron tomography. Coupled with an integrated X-ray source, the instrument will feature multi-modal capabilities. The complementary
The thesis attempts to assess the role of the OECD Commentaries in tax treaty interpretation process concluded between Non-OECD and OECD states. In order to reach the goal of the thesis the thesis discusses the legal status of the OECD Commentaries under public international law, in particular the interrelation of the Commentaries with the Articles of 31 and 32 of the Vienna Convention. The thesis
Ocean acidification, caused by the increased uptake of anthropogenic CO2, describes a change in the ocean’s carbonate chemistry. While its chemical processes are well understood, less is known about its biological and subsequently socio-economic consequences. However, there is evidence that marine organisms will be adversely affected by a decrease in pH and carbonate saturation levels. Fishery is
The growing popularity of Extended Reality (XR) attracts new people to enter the field. However, novices face challenges at the beginning of their journeys. Previous studies have identified the key difficulties based on real-world evidence and found that the barriers to entry were high. This thesis aims to guide novice XR practitioners in overcoming these challenges. To achieve this, empirical in
In light of the shortcomings of dominant recycling strategies in dealing with the plastic crisis, the circularity strategy of reuse is receiving increasing attention. Due to its goal of extending product lifespans, reuse is often seen as a more progressive strategy that aims to prevent waste rather than diverting it. Investigating the emerging phenomenon of reuse organizations in a multiple-case s
Local human rights defenders play a significant role in the realization and enjoyment of human rights. Working alone or in association with others, they peacefully advocate for and promote fundamental freedoms and human rights for themselves and for their fellow citizens. In the process, they document violations; raise awareness to rights holders about the rights to which they are entitled; remind
Den digitala omställningen har ökat genom åren och har fungerat till en fördel för företag och organisationer generellt. Hastigheten på transformationstillväxten har bibehållits i nutid, vilket har resulterat i att mjukvarusystem utvecklas kontinuerligt. Som en naturlig effekt av detta fenomen, bör aktuella företag alltid ligga i framkant för att förbli konkurrenskraftiga. Studier har visat att pr
A short introduction to optimal control problems is presented. For these problems the calculation of sensitivity matrices with the method of adjoint equation is shown. The adjoint equations are derived with the corresponding initial values. At the end two examples are calculated.
Popular Science Summary The aim of this thesis is to develop a method for the selective cleavage of a carbon fluorine bond with a transition metal. The main focus is directed towards the synthesis of a gemdifluoro, syn-diphosphine compound XX. When treated with iridium the metal should bind to the phosphines which keeps it close enough to the carbon fluorine bond to break it and form what is known
Distribution is a part of the supply chain and refers to the steps taken to move and store a product from the supplier stage to the customer stage in the supply chain. Direct shipment is a concept within distribution and refers to shipping direct between a supplier and a retailer or customer. Distribution is considered a key driver for overall profitability of a company since it directly affects b
In the last decades, scholars, managers and consultants have shown increased interest in identifying the characteristics of high-performance organizations. Searching for ways to improve organizational performance and respond to a growing demand for quality products and services in a rapidly changing environment, this subject is of special interest of managers in both public and private organizatio
Arlanda flygplats är en av Nordens största flygplatser, vilket gör att personbrandskyddet är väldigt viktigt. Ett platsbesök genomfördes på Terminal 4 på Arlanda vid projektets början i syfte att göra en brandteknisk riskvärdering av byggnaden. Under platsbesöket samlades information in om potentiella riskkällor och möjligheterna att utrymma undersöktes. Detta resulterade i flera potentiella brandArlanda is one of northern Europe’s largest airports servicing 18,4 million travelers in 2022. Ensuring the safety of everyone moving through or working within the building requires a large-scale safety and security infrastructure. This report narrows its focus to one of the older parts of Arlanda, terminal 4. The aim of this project is to evaluate the fire protection focusing on the safety of the
Background and Purpose: Possibilities to age in place are increasingly important with the demographic shift toward aging populations. With the Person-Place Fit Measure for Older Adults (PPFM-OA), older adults self-assess how their home and community environments suit their needs. The aim of the study was to evaluate the psychometric properties of the Swedish version of PPFM-OA. Methods: Four hund
Rocky planets may acquire a primordial atmosphere by the outgassing of volatiles from their magma ocean. The distribution of O between H2O, CO, and CO2 in chemical equilibrium subsequently changes significantly with decreasing temperature. We consider here two chemical models: one where CH4 and NH3 are assumed to be irrevocably destroyed by photolysis and second where these molecules persist. In t
Diet has a pivotal role in shaping the composition, function and diversity of the gut microbiome, with various diets having a profound impact on the stability, functionality and diversity of the microbial community within our gut. Understanding the profound impact of varied diets on the microbiome is crucial, as it will enable us not only to make well-informed dietary decisions for better metaboli
BACKGROUND: Self-reported mental stress is not consistently recognized as a risk factor for stroke. This prompted development of a novel algorithm for stress-phenotype indices to quantify chronic stress prevalence in relation to a modified stroke risk score in a South African cohort. The algorithm is based on biomarkers adrenocorticotrophic hormone, high-density lipoprotein cholesterol, high-sensi
Metachromatic leukodystrophy (MLD) is a fatal, progressive neurodegenerative disorder caused by biallelic pathogenic mutations in the ARSA (Arylsulfatase A) gene. With the advent of presymptomatic diagnosis and the availability of therapies with a narrow window for intervention, it is critical to define a standardized approach to diagnosis, presymptomatic monitoring, and clinical care. To meet the
