The purpose of this thesis was to investigate how extracellular vesicles extracted from cows milk interacts with the surfaces hydrophilic surface, DOPC bilayer surface, 95% DOPC and 5% DOTAP mixture bilayer surface and 1:1 ratio of DOPC and DOTAP mixture bilayer surface, and colloidally characterize EVs by determining the hydrodynamic radius and zeta potential. To determine the size and zeta poten
Inför en digitaliserad, global ekonomi, vari nära hälften av multinationella företagsvinster går obeskattade, står vi på randen till en ny ordning för gränsöverskridande företagsbeskattning. Med sin tvåpelarlösning söker OECD lägga de första byggstenarna. En internationell minimiskatt, att krävas ut från stora multinationella gruppers slutliga föräldrar, föreslås att mota baseroderande skatteplaneFacing a digitalized global economy, where almost half of multinational corporate profits go untaxed, we find ourselves on the verge of tax revolution. With its two-pillar solution, the OECD seeks to lay the first building blocks of a new system for cross-border corporate income taxation. To counter avoidance, states are presented with an international top up minimum tax, to be charged at multinat
The search for doubly charged Higgs bosons (H±±) aims at resolving the mass generation mechanism of neutrinos in the Standard Model. The current search by the ATLAS Same-Sign Dilepton group uses the decay product of H±± to a pair of same-sign hadronic τ-leptons, which is an extension of their previous search using same-sign dielectrons and dimuons. This thesis focuses on the study of one of the ba
All words in Swedish have a particular melody. There are two tonal patterns that are observed in different prosodic and morphological contexts – accent 1 and accent 2. The tone of accent 1 is the default melody in Swedish and is said to be of intonational nature. The melody of accent 2, on the other hand, only occurs in presence of certain suffixes in the word, hence, accent 2 is claimed to be a p
This thesis draws attention to China’s information management of its Arctic policy, and the way in which China has left out information in official English-language publications that could be deemed sensitive by Western actors. This thesis examines how the news media of Iceland has reported on China’s Arctic policy over two different periods, dating from 2012 - 2013 and 2018 - 2019, in order to me
National identity is used as a representation of what a country wants to transmit as its own impression of ‘self’, and usually it is formed around the concept of an ‘other’. Nonetheless, if two national identities are contradictory; it can hinder the development of desirable bilateral relations, which is the case of Japan and South Korea. Taking the Takeshima/Dokdo territorial dispute as a referen
The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame. A principle design wil
This thesis draws on eleven semi-structured interviews with Duterte supporters. It analyses how the president is perceived by Filipinos, more specifically by those who support him and live in Sweden and the Philippines, in order to provide an in-depth understanding of the appeal of Duterte to his supporters. The thesis focuses on the main reasons for Duterte’s popularity, the war against drugs and
As more and more In Vitro Fertilizaiton (IVF) treatments are performed each year, there is a need to better predict the outcomes of different stages of the treatment and hence get a better understanding of which hormonal and physical parameters affect the treatment outcome and in what way. In this study, the effect of interaction between baseline AMH (anti-mullerian hormone) and DFI (DNA fragmenta
Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. While both robustness and evolvability are necessary, embracing them simultaneously seemingly leads to an inherent conflict due
Tissue patterning during development is thought to be driven largely by gene regulatory responses to spatial gradients of molecular signals, known as morphogens. In this thesis, early patterning of the human neural tube is studied using two different gene regulatory network models. The models portray patterning in the rostral-caudal direction as a response to gradients of WNT and FGF signalling. T
Climate change denial tends to be prevalent among right-wing populists, but the underlying reasons for this remain unclear. Given that persistent climate change denial among the public could impede efforts to address the negative consequences of anthropogenic climate change, it is important to identify the psychological correlates of these attitudes. This thesis aimed to investigate the hypothesis
Purpose: To investigate whether the ambitiousness of sustainability performance target and/or issuer sustainability profile have an influence on Sustainability-Linked Bond (SLB) yield spreads. Methodology: The utilized econometric approach is OLS regressions on a cross-sectional data. The regressions use yield spreads as dependent variables, a self-constructed ambitiousness proxy, Average Annual
Sick absence affects companies both operationally and economically and the matter has become increasingly prominent following the COVID-19 pandemic. MedHelp Care is an e-health company working towards increasing workplace wellness by offering insights into absence and rehabilitation matters. Forecasting future absence levels could help with matters such as staffing and garner more insight into whi
Bakgrund: Enligt klinisk forskning visar ADL-taxonomin hög validitet och reliabilitet, men det finns inga studier kring svenska arbetsterapeuters erfarenheter av att använda ADL-taxonomin som bedömningsinstrument i sitt kliniska arbete. Det är viktigt att studera användarnas erfarenheter och synpunkter för att förbättra implementering av evidensbaserade metoder såsom ADL-taxonomin. Syfte: SyfBackground: The ADL-taxonomy as an assessment instrument shows high validity and reliability in the clinical research, but there is no study about occupational therapists’ experiences of using the ADL-taxonomy in clinical practice. It is important to study the users’ experiences and views to improve implementation of evidence-based methods such as the ADL-taxonomy. Aim: The aim of this study i
The Circular Economy (CE) came into existence due to the increasing environmental concerns produced by the legacy linear economy which consumes too many resources and generates a lot of waste. The CE is initiated on the ideas of reducing, reusing, and recycling resources by utilising the product information. Thus, this study investigates the product information which is to be carried by Digital Pr
With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo
Reinforcement is an important process of speciation that may occur when recently diverged lineages come into secondary contact and hybridize. If interspecific mating is costly, selection favors mechanisms that reduce maladaptive hybridization, actively increasing prezygotic isolation between populations and completing speciation. A pattern of reproductive character displacement (RCD) is often used
The purpose of this study was to identify trends in modern single family homes that might have an impact on residential fires. The study compared older homes with modern ones, starting from the 1960s and on to the 2000s. The fire service development during the same period was analyzed to see how their capacity to handle these fires have changed. The conclusions of this study were that many factors
