Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. Method: A mathematical model has been developed in
På senare tid har användningen av online kommunikation ökats drastiskt, speciellt angående chatapplikationer. Det gör både kommunikation snabbare och passar in väl med distansarbete. Då chatter i stora grupper kan bli röriga då det är många användare som skriver finns det potential för förbättring gällande strukturen och organiseringen av meddelandena. Det är målet med detta examensarbete att hittThe usage of online communication has increased heavily in recent times, especially chat applications. It both makes communication faster and fits well with remote work. As the chats of large chat groups can be messy with many writers there is potential for improvement in regard to the structure and organization of messages. This is the focus of this master thesis, what kind of effects using threa
The purpose of this study is to empirically investigate the relationship between unencumbered tangibility and cash holdings, and to evaluate if corporations consider them to be substitutable variables of corporate liquidity. The study relies on a panel data set and then employs a firm fixed effect regression model to estimate the strength and direction of the relationship of interest. It then proc
This master thesis project presents steps on the image processing and reconstruction of an aluminium open-cell metal foam from $\mu$CT tomographic data. In addition, it also considers the generation of architecture foams using Voronoi Tessellation in combination with sphere packing algorithms. The process creates a foam skeleton which is used together with morphological operations such as dilation
This thesis aims to investigate whether the implementation of IFRS has affected the accounting quality in Swedish companies. The results of this study is analyzed through the theory of information asymmetry and previous empirical studies. The study employs a quantitative method using linear regression analysis on market value of equity, book value of equity and earnings pre- and post-IFRS to inves
The substantial growth of private health insurance in 21st century Sweden has sparked debates about its potential effect on waiting times within the public health care system. Some argue that individuals with private health insurance are prioritized in the waiting list for health care, potentially leading to longer waiting times for those without private coverage. Conversely, others argue that pri
Establishing artificial carbon fixation in Escherichia coli as a model organism can open the door to utilization of carbon dioxide as a sustainable feedstock in industrial bioprocesses. Gleizer et al. (2019) developed an autotrophic E. coli strain which combines native and non-native enzymes to create an artificial Calvin Cycle. One of the native enzymes used is the NADH-dependent glyceraldehyde 3
In efforts to form resilience-building strategies and guide action across the globe, the Sendai Framework for Disaster Risk Reduction (2015) outlined four priorities, the first of which is Understanding Disaster Risk. The purpose of this research is to delve into the concept of disaster risk and see how it is understood by the duty-bearing entity tasked with reducing disaster risk (the government)
Intimate partner violence against men has been a rather unexplored topic within social science research but is now getting more and more attention. It has been shown that victimhood and masculinity is difficult to reconcile among both abused men and members of society. Using qualitative content analysis, this study investigated how male victims of heterosexual intimate partner violence is presente
Introduction: The modification of lignin to high-value low molecular weight compounds frequently results in complex mixtures of monomeric or oligomeric compounds. In addition, these organic acids can be applied as antioxidants or for the production of bioplastics. Background: The composition of lignin is complex. Utilizing technical lignin as a starting point, useful aromatic compounds can be ge
Japan’s influence in Southeast Asia has been enormous throughout history, whether in its military occupation, culture, or economic ties, and there is no doubt that Southeast Asia has developed under its influence. Have Southeast Asian states then developed and improved their human rights situation because of Japan? Or has Japan aggravated the situation being “blue washed”, by performing its busine
Menopause is a transitional process often hidden from society. Menopause can have varying degrees of effects on individuals, however there are possible enormous effects which can have impacts on individuals personal and professional lives. The following thesis explores menopause as a sociological phenomenon. The research specifically looks into how experiences of menopause appear in the workplace
This paper investigates Fox News’ television coverage of domestic terrorism in the United States from 2012 to 2022. This period spans the terms of both Republican and Democratic Presidents, the COVID-19 pandemic, large-scale civil protests, and the emergence of rightwing extremism as the foremost domestic terror threat. The empirical analysis is based on 287 transcripts from 24 Fox News shows. The
Denna studie syftar till att fördjupa förståelsen av konsumenters uppfattningar av värde i servicemöten som inkluderar självbetjäningsteknologier i jämförelse med personlig service. Genom att tillämpa kvalitativa forskningsmetoder utforskar studien hur konsumenter bedömer och beskriver olika aspekter av dessa servicemöten samt deras påverkan på individen. Resultaten indikerar att medan självbetjän
För att minska utsläppen av växthusgaser har nationella och internationella mål satts upp som medfört att andelen energi från förnyelsebara intermittenta energikällor kommer att öka. Ett resultat av detta är en mer komplex energimarknad och ett ökat behov av energilagring för att överbrygga gapet mellan produktion och efterfråga i tid och rum. En teknisk lösning som föreslås i Europeiska och Svens
Urban environments are often seen as the opposite of natural environments, with the belief that the built cannot accommodate the natural. However, this is a false perception. Ecological systems within urban environments are of great importance and can provide microclimates and habitats that do not exist in surrounding areas. Yet, this quality is rarely utilized because of the perception that built
Nature-based solutions (NbS) have proven effective in addressing urban sustainability challenges. This thesis focuses on bridging the gap in NbS short-term interventions, scale, and financial barriers. It examines the instrumentalization and implementation of successful long-term interventions from a policy and urban governance perspective, aiming to inspire cities and identify commonalities. The
Det här är ett arbete som undersöker den kritiska rörelse som växte fram och trotsade myndigheters och expertisens råd och restriktioner. En rörelse som mitt under en pågående pandemi tog till gatorna och proklamerade att våra friheter och rättigheter var hotade. Som en följd målades rörelsen också upp som ett hot mot demokratin, men vad ville de egentligen, hur lydde deras problemformulering och
This thesis investigates potential ways to improve the image stabilization in Axis Communications surveillance cameras. The current in-house developed stabilization algorithm, Axis EIS, stabilizes based on gyroscope measurements. We compare a purely gyroscope based stabilization algorithm with a gyroscope-accelerometer sensor fusion stabilization algorithm, image-based stabilization algorithms and
