The Light Dark Matter Experiment (LDMX) is a fixed-target missing-momentum experiment which hopes to detect dark matter in the MeV-GeV mass range. This is done by firing an 8 GeV electron beam at a thin tungsten target, where the electrons produce dark matter through a process called dark bremsstrahlung. Electrons which have gone through dark matter production can then be found by looking for miss
Denna uppsats undersöker hur artificiell intelligens (AI) uppfattas och anpassas i Kenya, med fokus på lokala språk, normer och kulturella värderingar. Syftet är att analysera i vilken utsträckning AI-system utvecklade i en global, ofta västerländsk kontext fungerar i kenyanska sammanhang och hur användare aktivt omformar tekniken. Studien bygger på nio månaders fältarbete i Nairobi och andra dela
Commercial hybridisation of seeds has created a large hybrid market that now dominates globally. In Rwanda, this market co-exists with a traditional system based on locally grown seeds. Local, farmer-grown seeds have traditionally been replanted to generate new seeds, which has kept farmers self-sufficient. Due to their genetic nature, hybrid seeds must be repurchased each season, creating a poten
The last decade and a half has seen intense research efforts into metal-halide perovskite (MHP) materials, as researchers have come to appreciate their excellent photo-electrical properties such as good radiative recombination rates and light absorption. As part of these efforts MHP-devices of different morphologies have been developed. Notably the enhanced nanophotonic effects of nanowire (NW) mo
Skuggdestinationer är platser som är belägna nära större etablerade turistorter med starka varumärken. Platser som befinner sig i periferin ställs inför utmaningar att synas och dra till sig besökare då många väljer att åka till de etablerade destinationerna. Efter pandemin uppstod en ökad vilja att besöka landsbygdsområden för att vara närmare naturen och få uppleva ett lugnare tempo. Intresset f
Studien undersöker den kortsiktiga aktiemarknadsreaktionen när amerikanska företag offentliggör förvärv i EU och vilka faktorer som förklarar förvärvarens kumulativa abnorma avkastning (CAR). Med en eventstudiemetodik finner vi att CAR i huvudfönstret (−15,+2) uppgår till 0,8 %, en effekt som är ekonomiskt relevant givet förvärvarnas storlek i studien. Avkastningsmönstret före annonseringsdagen ty
I vårt examensarbete undersöker vi varför vissa kvinnor lyckas nå toppositioner inom modebranschen medan andra kvinnor inte gör det. Studien fokuserar på modebranschen i Sverige och den är avgränsad till kvinnor som är verksamma inom olika delar av modebranschen. Vi valde modebranschen för dess tydliga könade och estetiska normer, vilket gör den relevant för att studera utifrån studiens syfte. Vi
This thesis introduces the theory of quasiconformal mappings on the plane. We give three different definitions of quasiconformal mappings: Differentiable quasiconformal map and two geometric definitions, one based on boundedness of the modulus of quadrilaterals and the other on ring domains. We also showcase when these definitions are equivalent. Then we prove that the geometric definition for qua
This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic
Membrane fouling, particularly by soft, deformable particles, is a significant challenge in microfiltration (MF) processes, leading to reduced efficiency and increased operational costs. This thesis investigates the formation of filter cake layers by numerically simulating fluid flow through microfluidic membranes designed with random, non-overlapping cylindrical micropillar arrays. The study aims
This paper concerns the development of thin films from lignocellulosic biopolymers using deep eutectic solvents (DES). The primary objective is to modify the lignin component and alter material properties, through inclusion of ethylene glycol in a previously proven choline chloride based DES. Additionally, citric acid-based systems are investigated as a greener alternative to more conventional DES
De svenska kriminella gängen beskrivs idag drivas av jakten på status och det talas om en heder bland gängmedlemmar som upprätthålls genom våld och kontroll, särskilt av kvinnor. Därmed har denna studie i syfte att undersöka hur hedersrelaterade normer tar sig uttryck i svenska gängmiljöer, samt vilka könsspecifika konsekvenser som detta medför. Två semistrukturerade intervjuer med två svenska ide
This thesis aims to reproduce the ATLAS detector measurements of the top quark mass, which is done by removing background events in the ATLAS detector dataset that has been extracted from the ATLAS Open Data (AOD). Understanding how it is produced and decayed, and how it can be seen in the detector. The coding for this project was done in ROOT via C++. We used simulations and a theoretical backgro
Recognizing that the labor movement is under-theorized as a political subject in degrowth literature, this thesis investigates potentials for alignment between degrowth and the Swedish labor movement through a focus on policies. It hypothesized that the two, from a policy perspective, may hold positions that could mutually reinforce each other. Departing from 14 policies proposed jointly in degrow
The Atiyah--Singer index theorem is a foundational result in mathematics, providing a deep connection between the analytical properties of an elliptic differential operator and the topological properties of its underlying manifold. This thesis focuses on a numerical approach to index theory for generalized Toeplitz operators. Building on the work of Loring and Schulz-Baldes, we utilize the spectra
This thesis explores how Chinese adoptees in Sweden negotiate their identity in a society characterized by a norm of whiteness. By collecting empirical research through seven interviews, it aims to shed light on Chinese adoptees and their experiences. Although transnational adoption discourse and research is fairly widespread in Sweden, there has not yet been made a lot of research about adoptees
Nightlife, often considered detached from political meaning regarded as solely serving self-indulgent purposes actually serves an important role in healing, identity exploration, and community-building within the queer community. Through an interpretivist research approach, this thesis examines a queer art rave collective Riposte based in London, as a space for queer healing and alternative politi
This study investigates teachers’ perspectives on the use of gamification in programming courses at Lund University’s Faculty of Engineering (LTH), focusing on implementation within the Moodle learning platform. Using a qualitative approach, semi-structured interviews were conducted with instructors who integrate gamification elements such as points, levels, progress bars, and immediate feedback i
With Sweden and the EU aiming to reach net-zero carbon dioxide emissions by 2045 and 2050, the interest in carbon capture technology such as Carbon Capture and Storage (CCS) and Carbon Capture and Utilisation (CCU) is on the rise, not least in hard-to-abate sectors such as waste incineration. Several Swedish waste management actors are now considering CCS or CCU, among them Tekniska Verken i Linkö
This study explores how unit managers within municipal health and social care describe their leadership in relation to trust-based leadership and how they work to foster psychological safety within their teams. A qualitative approach was applied, with eight semi-structured interviews conducted with managers from different departments. The analysis draws on theories of trust-based leadership, psych
