We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. We also consider the binary fraction which affect the retention of Black Holes. A typical Globular Cluster retains 0 or 102 BlThe Black Hole are popular objects in astronomy, a lot of scientists want to study their formation and evolution. Most astronomers agree with that there is a super massive black hole in the center of our galaxy. Also, some previous observations show that at least some clusters have black holes. As we all known, a typical black hole is formed by a core-collapse supernova of a massive star. The core

Biodiversity continues its devastating decline while Europe is facing an estimated 20 million ha of farmland abandonment until 2030. By reviewing scientific and grey literature, websites, and reports I investigate the impacts of rewilding on biodiversity in connection to abandoned farmland. In addition, I analyse the amount of abandoned farmland in three project areas from the Rewilding Europe org

Utveckling av en testningsbänk för att studera partiklar från kopplingar. Som en del av EU-projektet nPETS, vars syfte är att öka kunskapen om luftföroreningar från transportsektorn och deras påverkan på människans hälsa, så utvecklades en testningsbänk för att generera och mäta partiklar som uppstår från fordon med torrkopplingar. Luftföroreningar som uppstår från transportsektorn är ett välkänt

Memory impairment and prominent hippocampal atrophy are the most recognisable features of Alzheimer’s disease (AD). It has been known that hippocampus and surrounding medial temporal lobe (MTL) structures support memory processes. However, specific function of each MTL subfield remains to be elucidated. Not all MTL subfields are uniformly affected by AD pathology and the spread of AD pathology fol

K-pop is one of South Korea’s most famous cultural phenomena, and this thesis will delve into its impact outside of Korea‘s borders. The paper briefly discusses the background of the Korean Wave, and then dives right into the cultural form of K-pop and its connection with cultural diplomacy and soft power. The main focus of the thesis is to discuss the foreign perceptions of K-pop and that is done

Despite the importance of infrastructure, a big funding gap can be seen in infrastructure procurement. Public-Private Partnerships (PPPs) were once seen as a solution, but years later the results are underwhelming. As the industry can be susceptible to corruption, concerns have emerged about PPPs. To confront these concerns, this study aims to investigate if there is a link between corruption and

The study of the dynamic interaction between pantograph and catenary by computer simulation is useful as it allows us to obtain much information about this system while minimizing the cost of line tests. With a program validated by the norm EN 50318, the behaviour of a pantograph-catenary couple at a certain speed can be accurately estimated. With the program INPAC, a parametric study on the curre

At a time when books are being consumed more and more via digital aids and platforms, physical books have begun to take up less space in the market. Fortunately, technological development can offer the possibility to bring physical books into the future by adding interactive and multimodal elements to them. Is the traditional book in a stage of transformation to become something new? The combinati

The present thesis sought to inspect the yet-unexplored digital dimension of North Korean human rights activism, aiming to uncover the strategic digital communication wielded by a selected case study. The research was thus based on an explorative qualitative inquiry of the social media activity of Park Yeonmi, one of the most renowned North Korean defectoractivists in the West. A total of 90 eleme

The usage of open source software is growing and with it, the number of vulnerabilities that attackers can utilize in order to perform malicious activities. In order to mitigate them, it is therefore important to develop effective means of remediating said vulnerabilities. This thesis compares two different solutions for automating vulnerability remediation in regards to time efficiency. Both shar

The COVID-19 pandemic has helped raise awareness about climate change, creating an opportunity for changes in consumption patterns and travel behavior. This increased awareness has also reached the corporate world [1]. Companies are measuring their emissions and report this. The emissions of employee commuting is often calculated through surveys which are not accurate due to non- respo

Canals have always been an important part of The Netherlands and played a big role within the urban development of the cities. As many of the canals lost their functions by the 19th century, a lot were replaced with streets infrastructure. Replacing the canals with streets has affected the overall ambience of many neighbourhoods in The Netherlands. The elimination of the water element caused many
