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
This paper aims to examine women as formal leaders in social work, focusing on their own experiences, perceptions, and management of expectations regarding leadership and how expectations affect the practice of their leadership. This paper is based on a gender perspective where the focus is on examining the importance of gender and gender in relation to, among other things, expectations and ideals
English title: “Upper secondary school students' experiences of resistance against teaching practices in the Swedish subject” The present thesis is part of the research project When School Makes a Difference: Education in the Tension Field Between Vocational and Study-Preparatory Upper Secondary School Programs, in which researchers at the Department of Educational Sciences at Lund University
CCC and DCC are used to estimate the conditional correlation between a non-standard mix of GARCH, GARCH-M and a stochastic volatility model, all assuming Gaussian innovations. After demonstrating the theoretical soundness of this combination, a portfolio of ten assets with diverse return dynamics is constructed. Portfolio performance is evaluated using Value at risk, the Sharpe ratio, maximum draw
This study concludes the characteristics of male friendships and their connection to ideals of masculinity. Existing research tends to focus on younger men and loneliness. The purpose of the study is to understand male relations and the way masculinity affects men in the age of 65-85. The research questions are: How do masculinity ideals and norms affect older men in their social interactions and
The nature room is designed to reflect and portray the surrounding landscape, turning the building into a living mirror of its environment. A facade of reflective glass captures the changing sky, trees, and terrain, creating a strong visual connection between architecture and nature. Inside, rough limestone walls and carved details echo the textures of the local geology, grounding visitors in a sp
Relative Energy Deficiency in Sport (RED-S) is a condition arising when dietary energy intake is insufficient to meet the combined demands of training and normal physiological functions. RED-S negatively impacts bone health, and increases the risk of stress fractures. Yet, its effects on bone matrix organization and overall bone quality is not well understood. Collagen and the osteocyte cells'
This study aims to analyze the impact of digital transformation on internal control of CCB and examine how digital transformation reshapes CCB’s internal control framework (based on the COSO framework) and the challenges the company encounters in digital transformation.This paper adopts agency theory as the theoretical perspective and uses COSO as the main framework.Based on the comprehensive case
The primary objective of this study is to explore the perceptions of three inclusive marketing strategies—racial representation, AI-driven personalization, and unfiltered beauty—on consumer perceptions of brand authenticity and their connections to long-term brand loyalty in the makeup sector. The study aims to gain insight into how the combined application of these strategies shapes the perceived
Context. The adverse effects of interstellar extinction makes the optical range unsuitable for spectroscopic analysis of stellar populations in dust-obscured regions of the Milky Way. With new instruments available, high-quality spectroscopy in the near-infrared (near-IR or NIR) range is now feasible. However, this region of the electromagnetic spectrum is relatively unexplored for the purpose of
