This master thesis was done in collaboration between the division of Production and Materials Engineering at Lund University, Faculty of Engineering, and Nolato MediTor AB. The company, located in Torekov, offers a variety of solutions for the medical device and pharmaceutical industries. The project was performed in the extrusion department that manufactures a wide variety of medical tubes and ho
Denna studie undersöker den politiska kampanjmetoden dörrknackning (canvassing) med syftet att få en inblick i hur dörrknackarna upplever den retoriska situationen ute i fält. Det empiriska materialet har samlats in genom tio kvalitativa forskningsintervjuer och analyserats med Lloyd F. Bitzers modell “The Rhetorical Situation” (1968). Slusatserna är att dörrknackning som metod är situationell i sThis study examines the rhetorical situation of door-to-door canvassing through qualitative research interviews with partisan canvassers from the Social Democratic Party in Malmö, Sweden, with the theoretical framework of Lloyd F. Bitzer's "The Rhetorical Situation" (1968). The study concludes that door-to-door canvassing is situational in its form, and must therefore respond to audi
Alzheimer's disease is a neurodegenerative disease that often affects the elderly and is accompanied by cognitive loss. The disease is characterized by the formation of amyloid beta (Aβ) plaques and Tau tangles in the brain, and microglia, the brain's resident immune cells, have been found to play a critical role in the progression of the disease. Recent studies suggest that microglia may
Russia's invasion of Ukraine has caused division among nations, with large parts of the Global South either refraining from condemning Russia or outright criticizing the West for its pro-Ukraine stance. It highlights the need to examine Russia’s public diplomacy efforts and ability to attract parts of the Global South in the context of the war. Based on this notion, the following thesis examin
Denna uppsats syftar till att få en djupare förståelse för vilka utmaningar COVID-19 pandemin och övergången till distansarbete har skapat för chefer i Sverige, samt att förstå hur chefer kan överkomma utmaningarna som uppstår. Uppsatsen kan därför bidra med ökad förståelse kring svenska chefers ledarskap vid distans- och hybridarbete. Metodvalet i uppsatsen har bestått av insamling av kvalitativ
En partikelfysikers arbete är att beskriva hur naturens minsta beståndsdelar, subatomiska partiklar, interagerar. Detta är väldigt svårt då interaktioner är fundamentalt slumpmässiga. Inte ens den bästa fysikern kan därför säga exakt vad som händer när två partiklar kolliderar, men hon eller han kan istället räkna ut sannolikheten för alla olika händelser. Detta bygger på att fysikern har tillgångThe chirality-flow formalism provides a simple but efficient way to rewrite and evaluate Feynman diagrams and has recently been shown to also optimize automated numerical scattering matrix element evaluations in massless tree-level QED. In this thesis we extend the numerical QED model to massless tree-level QCD in the MadGraph5_aMC@NLO framework. It is shown that a good gauge choice for external g
The increased prevalence of obesity is causing challenges on individual and socioeconomic levels. Neuronal subtypes of the hypothalamus control appetite regulation through the secretion of peptide hormones and neurotransmitters. Our limited knowledge of early molecular patterning of the human hypothalamus sets a challenge to design human in vitro models for cellular studies and drug screening. In
In this thesis we introduce the notion of elliptic functions, and in particular Weierstrass' Elliptic Function, in order to define the modular function $\lambda$ on the upper half plane. We establish a group ismorphism between the unimodular transformations and $\Aut{\C\setminus\{0,1\}}$. In particular this gives two functional equations involving $\lambda$, and with these equations we show th
In an era of rapid technological advancements, the digital economy has witnessed significant transformations, resulting in the emergence of dominant technology giants. The rising dominance of companies like Google and Amazon has raised concerns in the European Union (“EU”) regarding fair competition and consumer welfare. This thesis comprehensively examines the impact of digital markets and online
Averting catastrophic climate change requires private businesses to reach net zero emissions while staying within 1.5°C of global warming. The nonprofit organization Project Drawdown and the literature suggest that companies have to engage all capacities to achieve ambitious emissions reductions, including their social power, governance, political advocacy, finance, and employee creativity. I eval
This Bachelor’s degree project investigates how to create a modular chair system. It should let the consumer combine different parts to create a chair that fits their home, style and needs. The focus is on how a low number of parts can be used in different ways to create differentcombinations. It should also be easy to replace and recycle all parts when needed. This document shows the full design
In this bachelors project I am exploring how Phase Change Material can be applied into an office chair to give a cooling effect and reduce the need for air conditioning. The motivation for the project was to find solutions to lower the energy consumption. The design process includes research and ideation to a developed concept with a display prototype.
Scaling up climate finance is vital for avoiding the worst impacts of climate change and limiting global warming. In this light, multiple Voluntary Net-Zero Alliances for Financial Institutions (VNZAFIs) have been founded, directing capital flows from financial institutions towards climate action. Nonetheless, the contributions of VNZAFIs to the Paris Climate Goals can be put into question. This s
Syftet med studien var att undersöka om juristers moraliska uppfattning skiljer sig från gemene mans moraliska uppfattning. Den teoretiska bakgrunden om moral utgick från Haidts “Moral Foundations theory”, i enlighet med denna teori utgick studien från att det finns fem olika moraliska principer som utgör den moraliska kompassen. Centralt för studiens teoretiska bakgrund om beslutsfattande och inlThe purpose of the study was to explore whether or not there are any differences between attorneys and the average citizen's moral notions. The theoretical background mainly focused on Haidt’s Moral foundations theory, in accordance with this theory the study adhered to the five moral foundations that constitute the moral compass. A main part of the theoretical background was also the theory o
This qualitative case study compares two different student aid systems, the universal Swedish one (CSN) with the needs-based German one (Bafög) to determine their effect to facilitate enrollment in university education and reduce socioeconomic inequalities. For this, tertiary students in Germany and Sweden were surveyed for their opinion on the equality of their respective student aid systems. Joh
Distributed software development (DSD) teams have become increasingly popular among organizations. While the distributed teams come with certain benefits such as reduced costs, availability of remote workforce and a bigger skill base, they also come with challenges. One of the main challenges in DSD teams is keeping the employees motivated while working in a virtual environment. As motivation in D
Som ett resultat av ökad efterfrågan på elektricitet från urban elektrifiering, den växande ekonomin och global uppvärmning står Indonesien inför stora utmaningar. För att lyckas med hållbar storskalig elektrifiering krävs stora mängder litiumjonbatterier som kan balansera elnätet. Den ökande efterfrågan på dessa har lett till brist på batterimineraler vilket försvårar situationen för landet. SaWith the increasing energy demand from urban electrification, the growing economy and global warming, Indonesia has some extensive challenges ahead. Additionally, growing demand for Li-ion batteries is causing shortages of virgin battery minerals in parallel with the increasing demand for energy storage to accommodate electrification. On the contrary, the future abundance of used electric vehicle

Background: In recent years, manually controlled drones have taken off on the commercial market, as well as in the agricultural industry and in humanitarian logistics. This has increased the interest in investing in autonomously controlled drones to increase efficiency and reduce costs. Some projects have been initiated in warehouses but the research in the field is still limited. Purpose: The pu
