Galaxer formas när enorma gasmoln kollapsar på grund av gravitation. Små ojämnheter får gasen att rotera vilket leder till att molnet pressas ihop till en disk. Stjärnor bildas av gasen som i sin tur fortsätter att rotera. Under tid dör stjärnorna och blir till gas igen som sedan bildar nya stjärnor. Interaktioner mellan galaxersker genom kollisioner och gravitationskrafter. Det kan påverka galaxThe Large and Small Magellanic Clouds (LMC & SMC) are the two largest galaxies orbiting the Milky Way (MW). The interactions between them have affected the evolution of both galaxies. The interactions have affected the galaxies differently depending on how strong they have been. Tidal forces from the interactions are argued to have produced a stream of stars and gas called the Magellanic Bridg

Recent years, geopolitical risks have dominated the news feed for the financial markets. There have historically been some geopolitical events that have resulted in major declines in the stock market and such a market day can be classified as a geopolitical Black Swan. The purpose of this essay is to investigate the area of CAPM beta and geopolitical risk where the main investigation is if beta is

Today, the digital transformation provides new avenues for women’s empowerment. Information and communication technologies (ICTs), including the internet, can contribute to greater gender equality by enabling everyone access to the same online resources and opportunities. Yet, the prevalence of a gender digital divide means that many women, not least in Tunisia and the Middle East and North Africa

Background: Mental disorders, symptoms of mental illness, and prevalence rates of such among athletes are equal to or exceed those of the general population, and research findings have suggested that athletes have more risk factors than the general population during the COVID-19 pandemic due to the far-reaching consequences COVID-19 restrictions have had on the world of sport. The study aimed to c

This thesis creates multiple indices to score and rank developing countries with regard to their suitability for engaging in debt-for-climate swaps, and thus identify the most suitable country candidates. The origin of debt-for-climate swaps lies in the 1980s, and after a period of diminished use and attention they have become a topic of discussion again, especially in the last two years. Desp

The COVID-19 pandemic sparked a global debate on intellectual property rights involving various actors including nation states, civil society, and business. In October 2020, South Africa and India proposed that certain intellectual property rights on COVID-19 health products should be temporarily waivered for the remainder of the pandemic invoking strong opposition from the pharmaceutical industry

Denna studie syftar till att undersöka synen på mänskliga rättigheter och demokrati i relat-ion till uppfattningar om folkbiblioteket som samhällsinstitution, samt vilken möjlig roll mänskliga rättigheter utifrån detta skulle kunna spela i en folkbibliotekskontext, mot bak-grund av statens människorättsliga skyldigheter. Utifrån kvalitativa intervjuer med folk-bibliotekarier, knutna till ett genom

Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. Using a standing acoustic wave, the particles with the equivalent acoustic properties are focused at the same point in the cha

This thesis explores the imagined futures of young Swedes with a focus on how they envision creating work-life balance and how they aim to divide their time between paid and unpaid work. This is done by analyzing written accounts of 168 upper secondary students from both university preparatory schools (UP) and vocational schools (VO) in a middle-sized town in Sweden. Three top-level strategies for

Introduction: International cooperation is essential for public health, as countries need to access medical equipment, combat health crises, and strengthen health capacities. Medical Diplomacy is a concept and practices that combines the goals of improving intergovernmental relations and health, by initiating and facilitating intergovernmental health cooperation. Objectives: This study specificall

This experimental study investigates how individual variation in cognitive functioning, specifically working memory, previous experience with language learning but also language background, influence language aptitude, in particular grammatical inferencing - the capacity to spot patterns in grammar - as measured by the LLAMA_F test. Firstly, the study explores individual factors hypothesised to in

Ungdomskulturer förändras med tiden och nya ungdomskulturer tillkommer i relation till samhällsförändringen. Samhällsförändringarna har lett till att nya ungdomskulturer har utvecklats, vara en av dem har präglats av ghettokulturen och macho-attityden från förortens kultur. Genom bland annat den svenska hiphopen och mobiliseringen av ungdomar i samhället har kulturen från förorten anammats av ungd

Human-induced climate change continues to have a disproportionate negative impact on people and the planet. The human dimension must be included to make a change to reduce the environmental challenges we are facing. As mobile digital technologies have developed, the use of gamification has emerged as a way to promote pro-environmental behavior. As the field is relatively new, the research on the t

We study the effect of Riksbank’s corporate bond purchase program on the yield spread of bonds and firm-level debt structure. We find evidence that the Riksbank’s corporate quantitative easing announcement reduces the yield spread of eligible bonds compared to the non-eligible bonds. The effect is significant for high-quality and low-quality IG-rated bonds; however, the AAA-A-rated bonds react mor

Virtual reality (VR) has dominated technology headlines in recent years with its ability to immerse users in a virtual world. This technology is changing the tourism industry dramatically. Previously, VR has been used mainly as a marketing tool to promote services and tourist destinations. But nowadays, VR is almost an essential technology, used in many tourism organizations to provide customized

In this thesis a concept for a new leg construction, for a force regulated Stewart Platform called Hexapod, was created. The design process for this concept was split into three major parts: the actuator, joints, and the frameless motor, which make up the dynamic elements, the legs, that move the Hexapod. The design of these three parts was approached in a similar fashion, through four phases. T

Due to COVID-19 and the penetration of OTT services, the cinema industry is suffering from audience loss. With this contextual change, the question of whether the cinema industry will survive is constantly rising. As motivation is known as the driving force for behaviour, this thesis focuses on the audiences who still visit the cinema and explore their motivations for cinema attendance to find wha

is an important area of study with implications for pharmaceutical development. Asymmetric catalysis is one way to perform enantioenriched products. To study this subject, enantiomerically pure Rh(I) complexes were synthesized to be applied as catalysts in these kinds of reactions. A new C2 symmetric dibenzo[a,e]cyclooctatetraene-ligand, 5,11-bis(3,5-bis(trifluoromethyl)phenyl dibenzo[a,e]cyclooc
