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

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“If we’re the worst, we’re the strongest. Then we have the most power." Honour culture within Swedish criminal gangs and its impact on women Swedish criminal gangs today are driven by the pursuit of status, and there is talk of an internal honour among gang members that is maintained though violence and control, particularly of women. This study thus aims to investigate how honour-related no

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

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

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

Sedan den första börsen öppnade 1602 i Amsterdam är drömmen för alla investerare att förutspå marknaden. Idag finns det en uppsjö av olika metoder för att ge ett hum om hur framtida marknader kan se ut. Är det möjligt att kombinera olika metoder för att skräddarsy en modell till just din portfölj? Svaret är: ja, den kombination av modeller som använts fungerar bra i teorin och presterar även bra 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

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

This study compares the financial performance of Islamic and conventional banks across the pre-, during-, and post-Covid-19 period from 2018 to 2024. Using the CAMEL framework, a Financial Performance Index (FPI) was developed to evaluate stability and resilience. The results show that Islamic banks consistently achieved higher FPI particularly during and post pandemic, indicating greater overall

Mental health issues among Swedish school children are a recurring concern. Although school health teams are legally assigned to primarily work on health promotion and prevention, previous evaluations have found these efforts to be insufficient. Based on our own observations during a school-based internship, we noticed how school nurses and school counselors carry out this work differently. The ai
