This thesis addresses the ongoing debate on the involvement of Chinese nationals in Ghana's artisanal and small-scale gold mining (ASGM) sector. Despite the Minerals and Mining Law, Act 703 (2006) prohibiting foreigners from engaging in ASGM, it is reported that about 50,000 Chinese nationals have migrated to rural Ghana to engage in illegal mining activities. This has caught the attention of

The accumulation of carbon (C) within boreal forest biomass is an important component of the global carbon cycle. Whilst it is understood that old forests contain a large carbon stock, the continued sequestration of carbon in these forests is debated. Swedish forests today are intensively managed as even-aged monocultures with short rotation times and have historically been managed through selecti

Systemic racism is a prevalent and longstanding problem in society that gained widespread public interest through the Black Lives Matter movement. Following the murder of George Floyd in May 2020, the movement expanded to Austria and brought heightened attention to the racialized branding of an Austrian brewery. Here, this expansion contributed to an existing resistance of the NO MOHR campaign aga

A sediment record obtained from a small lake in Warming Land, northern Greenland was subjected to biostratigraphic and geochemical analyses to investigate environmental and climatic changes during the last c. 2300 years. Macrofossil analysis, encompassing both vegetation and fauna, was applied to assess the ecological dynamics of the lake and its catchment. Geochemical proxies in the form of total

Titel: Porösa lipidnanopartiklar som läkemedelsbärare Ingress: Porösa lipidnanopartiklar är ett lovande alternativ till de lipidnanopartiklar som används i exempelvis vaccin mot Covid-19. Med sina stora porer är förhoppningen att de ska kunna leverera större molekyler och vara ett bra alternativ för läkemedelsleverans till celler. Porösa lipidnanopartiklar, på engelska 'sponge phase nanoparSponge phase nanoparticles are lipid-based particles with a porous structure, forming pores with sizes up to 13 nm in diameter. These particles have been proposed for drug delivery by loading cargo within the pores, similar to how ionisable nanoparticles are used today. The larger pores could allow for larger cargo to be delivered to cells. Sponge phase nanoparticles, 277 ± 29 nm in diameter, were

The field of Artificial Intelligence (AI) continues to revolutionise numerous sectors, and the banking industry is no different. This study investigates the rationales, challenges, and lessons learned from AI incorporation within Sweden's banking system. The research's objective is to elucidate the AI integration process and offer valuable guidance to organisations considering a similar te

Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. Detta examensarbete fokuserar på att studera mikromekaniska beteeWhat does the future sustainable package look like, and what is it made of? To answer this question, the micromechanical characterization of materials becomes an important parameter to explore and understand. In particular, the micromechanical behavior of thin paper materials is of interest due to its potential in sustainable packaging applications. This master's thesis focuses on investigati

Daily life with severe mental health (SMI) and cancer comorbidity entails multiple challenges. The study aims to explore everyday life experiences among individuals with SMI and cancer comorbidity from the perspectives of patients, significant others, and involved healthcare professionals. The study is registered in PROSPERO (CRD42021259604). A qualitative systematic review was conducted through s

Despite the end of the Cold War, the world still has thousands of nuclear weapons and adversarial relations between the countries that possess them. A nuclear war could cause large and abrupt global environmental change known as nuclear winter, with potentially devastating public health consequences. A significant line of natural science research characterizes nuclear winter and its potential effe

Frågeställningar: - Är det gynnsamt att byta till gröna tak på befintliga byggnader i tätbebyggda städer? - På vilket sätt gynnar gröna tak samhället? - Hur skiljer sig kostnaderna mellan ett traditionellt tak och ett grönt tak? - Varför läggs det inte gröna tak på befintliga byggnader i större omfattning? Syfte: Syftet med studien är att undersöka huruvida det är gynnsamt att byta taket på be

Katalysatorer har många funktioner och applikationer, till exempel som enzymer i vår kropp eller katalysatorer i bilar. En katalysator är helt enkelt en substans som sänker den energi som krävs för att en kemisk reaktion ska ske och därmed öka reaktionshastigheten. Själva katalysatorn förbrukas inte under reaktionen. Inte alla katalysatorer hjälper alla reaktioner, olika katalysatorer har olika anA model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. Two coverages of 2 ML and 0:33 ML V/ anatase TiO2 and the oxida

Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it. Ancient pathogens do not only pose a risk to their local environments as they can be aerosolized an

Sjöräddningssällskapet (SSRS) driver idag ett projekt där man utforskar möjligheten att använda drönare vid uttryckning till havs. I detta examensarbete har en mjukvara för att styra en drönarkamera implementerats. Den har sedan utvärderats i labb och under en riktig flygning i Göteborgs skärgård.The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. In the thesis, the GCI has been

We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. Then we investigate the tails of innovations of ARMA-GARCH models using the Peaks over thresholds method and find that the distributions of stock returns are asymmetric

Ice-marginal moraines are widely used as indicators of palaeoclimate in mountainous regions, yet the genetic processes of their formation remain incompletely understood. Here, we present new data on the geomorphology and sedimentology of annually formed moraine ridges in the foreland of Gornergletscher, Switzerland, with the aim of reconstructing the processes of their formation, assessing their p

In the global agenda for sustainable development, quality education is a defined priority. Therefore, it is significant to assess how topics of sustainable development are taught in mandatory school. The present thesis purposes to analyse the written curricula for Education for Sustainable Development (ESD) of Cuba, France, and Romania – the three countries top-ranked by the United Nations in 2020

Previous research has shown that the relationship between the news and parliament is complex and highly variable. Studies have found that in many countries, parliament has minimal influence on the news. However, in the UK, a reciprocal influence between parliament and the news was found, with the media having a stronger effect. This thesis investigates how the news and parliament affect each other
