Som en del i klimatomställningen av svåråtkomliga sektorer som sjöfart, flyg, och kemiindustri kan elektrobränslen komma att spela en viktig roll. I Sverige har e-metanol väckt intresse, och flera produktionsanläggninar är planerade eller under byggnation. Dessa kommer att vara stora elkonsumenter, men på grund av den traditionellt icke-flexibla metanolsyntesprocessen finns det frågetecken kring hAs a part of the climate transition of hard-to-abate sectors such as shipping, aviation, and chemical industry, electrofuels may play a key part. In Sweden, e-methanol has gained interest, and several production facilities are currently planned or under construction. These will be very large electricity consumers, but because of the traditionally inflexible methanol synthesis they may not be able

This paper examines the relationship between female representation on corporate boards and financial performance in Swedish publicly listed companies from 2015 to 2023, excluding the year 2018. This study explores whether a higher proportion of women on boards of directors correlates with improved financial outcomes, measured by Tobin's Q. The empirical strategy employs both pooled Ordinary Le

With the Large Hadron Collider (LHC) at CERN undergoing a major upgrade, including enhancements to the luminosity capabilities, it is essential to upgrade the main detector's components, especially ATLAS's inner detector, to ensure optimal performance. This thesis investigates the reliability testing of Inner Tracker (ITk) modules for the ATLAS experiment. It contributes to the development

Den grupp kemiska ämnen som är orsaken till att chilipeppar kan upplevas som brännande, varmt men även starkt kallas för kapsaicinoider. Anledning är att dessa ämnen interagerar och binder till värmereceptorer i vår kropp, vilket läkemedelsindustrin har intresserat sig för. Dessa ämnen har nämligen smärtlindrande egenskaper och har även visat sig vara effektiva mot sjukdomar som bland annat neuropChili peppers are known for causing a pungent sensation due to the presence of capsaicinoid compounds in their fruits. In the Capsicum genus, capsaicin biosynthesis relies on the condensation of vanillylamine and the fatty acid 8-methyl-6-nonenoic acid, a reaction catalyzed by an acyltransferase. Currently, capsaicin has become a highly relevant molecule to the pharmaceutical industry due to its a

Kollektivtrafiken skapar nytta för både privatpersoner och samhället i stort, och bidrar med bemötandet av en rad samhällsmål relaterade till miljö, transportsäkerhet och tillgängliga transportlösningar. För att tillåta fortsatt utveckling av en konkurrenskraftig kollektivtrafik i Sverige, kartläggs och analyseras trender, utmaningar och utvecklingsmöjligheter. Kollektivtrafiken utmanas av bland Public transportation systems provide accessible transport options for all citizens, reducing environmental impact by lowering emissions, improving traffic safety, and promoting social equity and public health. It plays a crucial role in achieving national goals related to sustainable development and climate change mitigation. However, in its aim to increase competitiveness to other modes of trans

This paper analyzes the impact of trade shocks on the female labor force. The EU enlargement of 2004 entailed a potential trade shock for Germany as trade barriers fell. With an increase in export opportunities and an increase in import competition, the enlargement could have an effect on the German labor market. The analysis is a quantitative approach of a panel data analysis and ranges between 1

Lignin är ett ämne som finns i alla växter och bidrar med stabilitet genom och skydd mot an-grepp från bland annat svampar och bakterier. Ämnet produceras i huvudsak som en biprodukt när träd används för att producera pappersmassa genom olika metoder, och omkring 100 miljoner ton lignin produceras varje år. Tack vare att lignin har en speciell struktur, där aromatiska molekyler är sammanlänkade i To decrease the dependency of fossil-based raw materials in society, and with that, the chemical industry, new and sustainable raw materials need to be investigated. Lignin is an abundant aromatic biopolymer, that can be used to produce, e.g. aromatic fine chemicals through depolymerization. In this master’s thesis, different homogeneous and heterogeneous catalysts were screened for oxidative depo

The study investigates how small and medium-sized enterprises (SMEs) entrepreneurial marketing activities on social media instigate cognitive, emotional and behavioural aspects of customer engagement. Using a qualitative research design and conducting semi-structured interviews, the study explores how these marketing strategies instigate different types of consumer behaviours and engagement levels

Manufacturing companies increasingly adopt the strategy of adding services to their product offerings to differentiate themselves and overcome product commoditization. The bundling of products and services in complex product-service systems has the potential of high value creation and superior customer experiences. However, this shift requires business model innovation and acquisition of capabilit

The Klein--Gordon equation is a relativistic wave equation which models a relativistic spin-free particle. In this thesis we investigate the asymptotic behaviour of the linear Klein-Gordon equation with a rapidly decaying potential in one space dimension. This is done by first studying the case with zero potential and finding asymptotic estimates using the method of stationary phase. This is a met

Klorparaffiner är ämnen bestående av klorerade kolvätekedjor och kan indelas i tre grupper: korta, mellan och långa ämnesgrupper. Denna rapport syftar till att sammanställa tillgänglig kunskap om klorparaffiner i helhet med inriktning på föroreningens förekomst och dess implikation på grundvatten. Samtliga ämnesgrupper har använts flitigt sedan 1930-talet inom metallbearbetning och plasttillverkniChlorinated paraffins are substances composed of chlorinated hydrocarbon chains and can be categorized into three groups: short, medium, and long chain compounds. This report aims to compile the available knowledge on chlorinated paraffins as a whole, with focus on the occurrence of these pollutants and their implications for groundwater. All groups of chlorinated paraffins have been extensively u

With future technologies and Industry 4.0, the need for robust and accurate positioning to optimize productivity and industrial operations increases. The previous positioning methods using triangulation or angle-of-arrival are not good enough, especially not for clutter-dense factories with poor line-of-sight conditions. For this thesis project, a convolutional neural network model was trained t

Euklidisk geometri var den första ge- ometrin som man stötte på i grundskolan, allt från trianglar till cirklar. Samtidigt fick man lära sig att inget av dessa objekt finns i verk- ligheten. Det var inte förrän Benoı̂t Mandelbrot (1924-2010) insåg att många naturfenomen är så oregelbundna och komplexa att de inte kan beskrivas med euklidisk geometri. I detta sam- manhang verkar Mandelbrots citat vLet $\dim_H(\mathcal{J}_\epsilon)$ and $\dim_H(\mathcal{J}_{i\epsilon})$ denote the Hausdorff dimension of the Julia set of the polynomials $f_\epsilon(z) = z^2 -2 -\epsilon$ and $f_{i\epsilon}(z) = z^2 -2 +i\epsilon$ receptively for small $\epsilon>0$. This thesis contains two main Theorems, both dealing with the upper bound for the asymptotic behaviour of $\dim_H(\mathcal{J}_\epsilon)$ and $\dim

As global energy demands rise and the need for sustainable solutions becomes more urgent, so efficient ammonia production is fundamental. Traditional methods, such as the Haber-Bosch process, are both energy-intensive and environmentally harmful. This research investigates an alternative by developing a catalyst for the electrochemical reduction of nitrate to ammonia, using Iron Nitrate Hexahydrat

Given the pressing environmental crisis, marked by climate change, biodiversity loss, and deforestation, precise land cover monitoring has become crucial. In this thesis, we explore the use of privileged information to enhance land cover classification using deep neural networks. Our study specifically focuses on how to best utilise all available data, by leveraging a machine learning framework kn

Mängdlära är den gren av den matematiska logiken där man studerar så kallade \textit{mängder}. I axiomatisk mängdlära undviker man att definiera begreppet \textit{mängd}, men det är meningen att mängder ska bete sig som samlingar av objekt av något slag. Som alltid i matematiken börjar man med att skriva ned en lista med axiom, från vilka man sedan försöker härleda en så rik teori som möjligt. DetWe investigate the strength of the Ultrafilter Lemma in comparison to the Axiom of Choice. In particular, we prove that a number of classical mathematical theorems are equivalent to the Ultrafilter Lemma over $\sf ZF$, and we study a few results which are typically only obtained in $\sf ZFC$ (as opposed to $\sf ZF$) but which can also be proven from the conjunction of $\sf ZF$ with the Ultrafilter
