Enzymatic hydrolysis using immobilized lipases for the production of free fatty acids and glycerol is a promising alternative to the current industrial standard. This study investigates a set of hydrolysis reactions catalysed by four different immobilization techniques to increase the knowledge on two-phase systems. The evaluation of how water purity, buffer salts, and water amount affect the reac
This study explores the renewable energy cooperation between China and the Gulf countries, particularly Saudi Arabia and the United Arab Emirates, focusing on how this collaboration addresses underlying structural asymmetries. These asymmetries include China's technological advancements, institutional frameworks, and discursive power, as well as the Gulf's resource and capital endowments.
This thesis investigates the effects of monetary policy shocks, both domestically from the Swedish Riksbank and internationally from the European Central Bank, on eight macro-sensitive Swedish equity indexes over the time period 2004-2024. Employing high-frequency yield changes around policy announcements, we extract level, slope and curvature factors via principal component analysis and use these
Multi-dimensional spectroscopy is a technique used by scientists to capture ultra-fast quantum effects. In particular, it uses several different frequencies to investigate nonlinear responses. Here we use this technique and apply it on a system of 2 spin-1/2 particles having some magnetic moment, and investigate the behavior of the probability density for a certain spin-state as well as the spin e
Detta examensarbete syftar till att utvärdera om användningen av historisk testdata kan bidra till en förbättrad testprocess. I rapporten presenteras två JavaScript-algoritmer utvecklade av uppsatts- författarna, createTestRun och updateTestRun, som är specifikt utvecklade för att optimera urvalet av testfall och minimera redundans mellan testkörningar. Algoritmernas bygger på historisk data som hThis thesis presents an approach to utilize historical test execution data for improving the test process within a Quality Assurance (QA) department. The thesis research introduces two custom-built JavaScript algorithms, createTestRun and updateTestRun, designed to optimize the selection of test cases and effectively reduce redundancy in between test runs. The algorithms were developed by the thes
I takt med att hållbarhet blir viktigare söker många företag inom jordbrukssektorn lösningar för att fasa ut fossila drivmedel. Utmaningen blir ännu mer komplex när ersättningen ska vara kompatibel med en existerande fordonsflotta, utan investering i nya fordon. Denna studie jämförde fyra kommersiellt tillgängliga och förnybara drivmedel med referensbränslet diesel. De undersökta drivmedlen är HVAs sustainability becomes more important in today's society, many companies in the agricultural sector are looking for new alternatives to fossil fuels. The challenge becomes even more complex when the replacement must be compatible with an existing vehicle fleet, without requiring new investments in vehicles. This report compares four commercially available and renewable fuels, using convent
This thesis investigates cost inefficiencies within the inbound logistics operations of Roam Electric, a Nairobi-based electric vehicle manufacturer. As Kenya’s electric vehicle market expands, managing logistics costs becomes increasingly critical for local firms navigating infrastructural, regulatory and operational challenges. This research adopts a holistic single-case study approach and devel
This thesis investigates the sustainability of Sweden’s reformed pension system, first introduced in 1998. The new reform addressed long-term demographic challenges, particularly population ageing. By linking pension benefits, the new system has systematically shifted financial responsibility from the state to the individual. The study assesses whether the motivation behind the reform has taken
The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the
Migraine is a highly debilitating neurological disorder that affects approximately 15% of the global population. It is most commonly associated with severe headaches that can leave sufferers bedridden, but its impact extends beyond the attacks themselves. The disease presents in various forms, ranging from sporadic attacks to regular ones following the female hormone cycle, and chronic migraine, w
This thesis examines the literary space of Macondo and its transformation due to external national influences in One Hundred Years of Solitude (1967) by Gabriel García Márquez. A case study is conducted of three key episodes in Macondo’s increasing contact with the state. The objective of the study is to analyze their respective spatial logics as a basis of the production and transformation of Mac
Detta arbete undersöker spridningen av Recolabs avloppssystem Tre rör ut som är en innovation som syftar till att separera och återvinna gråvatten, svartvatten och matavfall för ökad hållbarhet. Trots tekniska fördelar har systemet stött på hinder i bygg- och VA-sektorn, särskilt kring implementering och informationsspridning. Syftet har varit att identifiera faktorer som främjar eller försvårar s
Neural radiance fields enable photorealistic 3D scene representation but lack semantic understanding for object-level segmentation in complex indoor environments. This work addresses 3D object segmentation challenges in indoor scenes by integrating 3D Gaussian Splatting with 2D segmentation masks. I analyze existing segmentation methods across visual quality, accuracy, and efficiency dimensions, t
Climate change is an escalating global issue, with various parts of the world being impacted differently depending on their geographic placement, development status and financial resources. Over the last couple of decades, the intensified climate change impacts have made the climate a subject to be securitized. This happens when a securitizing actor, like a state representative, articulates the cl
October 7th 2023 a terror attack on an Israeli music festival took place. This would subsequently escalate the conflict between Israel and Palestine, with many calling it a genocide of the Palestinian people. This thesis investigates how pro-Palestinian demonstrations in Lund and Malmö following October 7th can be understood in relation to police strategies and Anne Nassauer’s theory about situati
This thesis investigates how government communication officers navigate the strategic challenges posed by homeless media—informal, unregulated digital actors that increasingly shape public discourse in Indonesia. Drawing on qualitative interviews with eleven officers across national-level agencies, the research applies the Government Communication Decision Wheel (GCDW) and the concept of instituti
This thesis explores how individuals experiencing Postural Orthostatic Tachycardia Syndrome (POTS) constitute themselves as entrepreneurial subjects within contemporary neoliberal culture. Through 6 semi-structured interviews with Swedish women suffering from POTS, this study explores the subjectivities formed at the intersection of chronic illness and neoliberal regimes of truth. Drawing on Fouca
Gestures are usual companions to the words we speak, either enhancing them or simply accompanying them. Multiple studies focus on the relationship between gestures and speech, and even how they might affect who is listening. In more recent times, the field of investigation expanded to include insights into human behaviour in virtual contexts, making the most of the headsets worn by the users to, i
The last century has been a turbulent period in Cambodia, yet in the recent decades it has emerged from conflicts and humanitarian crises and become one of the world’s fastest-growing economies. This transformation was enabled in large part by foreign aid (ODA) and foreign direct investment (FDI). This thesis analyses the mechanisms by which ODA and FDI influenced the economy individually and in c
