Academic interest in economic inequalities has investigated the patterns of inequalities perpetuated by colonial rules across Africa over the past two decades. The findings highlight that, at a country level, there are biased investment policies favoring European settlers and encouraging the extraction of resources. Considering the importance of regional inequalities in Tunisia in the modern er

Bilingualism has become increasingly prevalent globally, with about half of the world's population being bilingual by 2012. This growing trend has prompted cognitive research to explore the effects of bilingualism on executive functions. The Bilingual Advantage (BA) theory posits that bilingual individuals experience enhanced cognitive abilities due to their practice in managing multiple langu

In this thesis, we study modeling approaches for the Cahn-Hilliard equations utilizing the Eyre approximation for first and second order in time accuracy. We first considered the Cahn-Hilliard equations and then expand our study by adding the Navier-Stokes coupling. We begin with a study concerning preconditioners, grid size options, mobility functions, energy density discretization, and time-step

Morgondagens energisystem står inför stora utmaningar och snabba förändringar både i Sverige och i världen. För att nå ambitiösa klimatmål ses elektrifiering som en viktig lösning på problemen, där Svenska Kraftnät räknar med en nära fördubbling av efterfrågan på el till 2045. Denna ökning, till stor del driven av förnybara energikällor som är svårare att planera och pronosticera, innebär betydandThe energy system of tomorrow faces major challenges and rapid changes both in Sweden and worldwide. To achieve ambitious climate targets, electrification is seen as a key solution, with the Swedish TSO projecting a near doubling of electricity demand by 2045. This increase, driven largely by renewable and intermittent energy sources, poses significant challenges for grid stability. Consequently,

This project delves into two prominent yet occasionally contentious markets: alcohol and fragrance. The overarching goal is to intertwine these industries. The project aims to navigate these complexities by research and exploration.

Föreställ dig att du går ut ur ditt hus och slår ett mynt. Får du huvuden går du ett steg åt vänster och får du svansar går du ett steg åt höger. Om du fortsätter denna process, är det garanterat att du kommer tillbaka hem? Det är möjligt att du bara vänder på huvudet och därför aldrig återvänder hem. Det visar sig att även om detta är teoretiskt möjligt är sannolikheten för att det händer noll, oShowing when random walks are transient or recurrent is the central topic we investigate in this thesis. To be able to find the conditions of a random walk, we develop techniques gained from knowledge about electrical networks developed from Snell and Doyle’s “Random Walks and Electrical Networks” (1984). We aim to use these techniques from Snell and Doyle’s work to be able to find conditions of r

Seagrasses provide valuable ecosystem services, benefitting both marine species and humans by providing coastal protection and erosion control which is significant as 898 million people lived in low-elevation coastal zones in 2020. However, seagrasses worldwide have been declining and in Sweden, the eelgrass Zostera marina has decreased heavily since 1980. One cause for seagrass loss in temperate

In March 2018, the Turkish armed forces, together with the Syrian National Army, seized control of the Syrian district of Afrin bordering Turkey as a result of the military offensive called 'Operation Olive Branch'. This takeover marked the beginning of Turkish military rule of Afrin, which has now extended over six years. Afrin’s case is a significant example of Turkey's broader forei

Den svenska dataspelsbranschen har historiskt sett varit starkt mansdominerad, och trots en ökad representation av kvinnor kvarstår stora utmaningar när det gäller jämställdhet, särskilt i högre positioner. Syftet med denna studie är att undersöka om det finns hinder, såsom ett "glastak", som hindrar kvinnor från att nå ledande roller inom branschen, samt att utforska vilka strukturer so

Multitasking, increasingly prevalent with the rise of digital tools and fast-paced environments, has become integral to daily life. Although it enhances our ability to manage several tasks simultaneously, it also poses challenges to learning and information acquisition. This study investigates how multitasking impacts the formation of relational memories, focusing on the role of eye movements. Par

As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip

The global tourism industry faces significant sustainability challenges, with environmental degradation and social inequities threatening its long-term viability. This is particularly critical for developing urban centres like Lagos, Nigeria, where rapid tourism growth has intensified environmental and social pressures. This thesis aimed to gain a better understanding of the role of Small and Medi

In this bachelor’s thesis, “Is Sustainability H&M’s Utopia? A Qualitative Analysis of H&M’s Sustainability Report”, we investigate H&M’s journey towards sustainability through an analysis of their sustainability reports from 2002, 2012, 2022 and 2023. This analysis is completed with the help of Ernst Bloch’s theory of utopia, performativity theory, Marxist theory and decolonial theory.

Tidigare forskning belyser den ökade användningen av big data och dess påverkan på konsumenters integritet, attityder och inställningar, vilket generellt visar en negativ syn på insamling av personlig data.

Dry reforming of methane (DRM) is a promising method for carbon dioxide utilization and hydrogen production, converting CO2 and CH4 into syngas (H2 and CO) using catalysts. Despite its potential, industrial implementation has yet to prevail due to challenges in loss of activity of the catalyst. Carbon deposition (coking) and catalyst particle agglomeration (sintering) occurring during the DRM reac

This thesis investigates the outcomes of economic divergence during the neoliberal period in Guatemala and Costa Rica (1985-2020). The application of social capabilities: transformation, autonomy, inclusion and accountability allowed us not only to show the diverted social and economic paths, but also to inspect further and delve into the complex social dynamics in place. There was significant pro
