Zinc Chloride Recovery from Textile Recycling Wastewater Using a Multi-stage Membrane Filtration Process

Textile waste presents significant harm to the environment, prompting the development of advanced textile recycling technologies. One such process recycles cellulosic fibers using zinc chloride (ZnCl2) at certain hydration levels to dissolve the cellulose, which is later precipitated by the addition of water and can be re-spun into new fibers. However, this process uses large amounts of zinc chl

The World is Your Office

Research Question: How do Swedish coworking firms internationalise, and what are the Key Success Factors allowing for a successful internationalisation? Purpose: This study investigates what drives international expansion for Swedish coworking firms. It also sees why these internationalisation projects were or were not successful. By identifying the key factors behind the projects, the study aims

Mama, I Wanna Go Home. The Intersectionality of Early Forced Unions in Mozambique.

This thesis illustrates the issue of Early Forced Unions (EFUs) in Mozambique, and its intersecting aspects. The enforcement of The 2019 Law on Preventing and Combating Premature Unions is established in the country, however, demonstrates a gap between legislation and practice. Throughout this thesis, factors of EFUs will be considered - financial vulnerability, cultural and traditional norms, pat

Beyond Borders: How Kazakh Tech Startups Initiated Their Global Journeys

The international business literature predominantly explains internationalization through the lens of developed countries and well-established firms, offering limited insights into how emerging market startups expand globally. To address this gap, this study investigates the internationalization processes of technology startups from Kazakhstan. Employing a qualitative research design, semi-structu

Real-Time Audio Processing on FPGA for Microphone Arrays

The widespread adoption of drones has presented new requirements for reliable localization and tracking systems. For this reason acoustic sensing has become an area of growing interest for a passive and cost-effective solution. However, process- ing large amounts of microphone data in real time presents significant hardware challenges. This thesis studies two different types of signal channelizati

Tidewater glacier retreat on Svalbard in the past, present and future

Tidewater glaciers on Svalbard are sensitive indicators of climate change and play a crucial role for Arctic ecosystems. The widespread retreat of tidewater glaciers across Svalbard highlights the need to quantify retreat rates and project when these glaciers will become land-terminating. This study investigates tidewater glacier retreat during historical (1936–1990) and present (2012–2024) period

AI in Audit: A Socio-Technical Exploration of Cybersecurity Vulnerabilities

Abstract Seminar date: June 3, 2025 Course: BUSN79 Degree Project in Accounting and Finance, 15 hp Authors: Timothée Mortgé and Mara Segveld Advisor: Liesel Klemcke Examiner: Anna Häger Glenngård Key words: Artificial Intelligence (AI), Cybersecurity, Vulnerabilities, Audit, Socio-Technical Systems (STS) theory Purpose: This study explores how AI adoption influences cybersecurity vulnerabilities i

Climate and ditch management impact on decomposition in northern peatland: findings from the Tea Bag Index and dissolved organic carbon characteristics

Carbon sequestration and long-term carbon storage are fundamental characteristics of northern peatland ecosystems. A key process influencing the carbon balance is the decomposition of litter and peat, which not only emits carbon to the atmosphere but also releases dissolved organic carbon (DOC) to recipient waters. However, these processes are susceptible to shifts, as climate change and managemen

Under pressure - En litteraturstudie om sjuksköterskors upplevelse av närståendes närvaro vid hjärt- och lungräddning.

Bakgrund: Hjärtstopp sker plötsligt och antalet hjärtstopp på akutmottagningar i Sverige har ökat mellan 2008 och 2023. Sjuksköterskors upplevelse av att utföra återupplivningsförsök framför närstående har visat sig vara ett splittrat ämne och en ny sammanställning av forskning om sjuksköterskors upplevelser behövs. Syfte: Att beskriva sjuksköterskors erfarenheter av närståendes närvaro vid återu

Using Similarity to Accelerate the Primal-Dual Hybrid Gradient Algorithm for Linear Programming

This thesis investigates the use of several acceleration schemes to improve the performance of the primal-dual hybrid gradient algorithm for linear programming (PDLP), a state-of-the-art first-order method for linear programming (LP). The three main acceleration schemes investigated are: Polyak heavy ball momentum, Nesterov acceleration, and steering vectors selected in a residual momentum directi

Who is to blame for juvenile delinquency?

With growing concern over organised crime in Sweden, increased attention has been directed towards children's involvement in escalating violence. Children are portrayed both as victims of coercion and as voluntary participants, reflecting a dual approach in governmental policy. This study investigates how the issue of children's involvement in criminal activities is problematised in three

Aliphatic β-Blocked Ligands in POCOP Pincer Complex Synthesis

Introduction: Synthesis of novel aliphatic POCOP pincer complexes with β-blocking alkyl groups. Background: An issue with Aliphatic POCOP pincer complexes is that the sought-after C=M bond is unstable with previous attempts forming aromatic groups or decomposing completely under heating. By introducing β-blocking elements to the aliphatic POCOP pincer ligands could this mitigate the decompositio

Effective Judicial Protection and the Rule of Law in the European Union: A doctrinal analysis of Articles 19 (1) TEU, 47 CFR and 2 TEU

The effective judicial protection has always been a key concern for the Court of Justice. This thesis analyses the development and constitutional consolidat-ion of effective judicial protection in European Union law. Through a doctrinal and case law analysis, the study traces how effective judicial protection evolved from a procedural limitation rooted in the logic of the Rewe effectiveness into a

Optimization and Analysis of Recoil-γ(γ) Data Near 56Ni

An experimental campaign took place at the Argonne National Laboratory (ANL) in the summer of 2020. Its goal was to study the exotic modes of decay of neutron-deficient nuclei located near 56Ni. For this thesis, the part of interest from the campaign is the experiment studying the fusion-evaporation reaction resulting from the collision of high-energy nuclei of 36Ar and a 24Mg target, creating exc

Digital inspelning av blodtrycksmätning under magnetisk resonanstomografi

Background: Invasive blood pressure (IBP) monitoring during magnetic resonance imaging (MRI) is primarily used in research and intensive care. A monitoring system displays IBP in real time, and there is currently no solution that enables digital recording of this data. The aim of this project was therefore to facilitate clinical research by enabling digital recording of invasive blood pressure. Me

Östra Sandgatan 5 - Ombyggnad av industribyggnad från 1950-talet till bostäder

Med en ökande befolkning ökar även behovet av bostäder. Genom ombyggnation av befintliga äldre byggnader kan man ge de boende en modern standard och minska energianvändningen. Att återbruka byggnader ger oftast ett mer hållbart byggande med mindre avfall och koldioxidutsläpp jämfört med att riva och bygga nytt. Syftet med denna fallstudie är att undersöka hur en industribyggnad som uppfördes 1952 With an increasing population, the demand for housing also increases. Due to renovation and retrofitting of the housing stock it is possible to give the future resident a modern housing and at the same time reduce the energy demand for the building. Reusing buildings is often a more sustainable way to develop housing because it results in less waste and lower carbon dioxide emissions compared to d

The effect of AI recommender systems on consumer trust and purchase intention under varying levels of risk

Purpose: This thesis investigates how the source of product recommendations, specifically, whether delivered by a human expert or an AI system, affects consumer trust and subsequent purchase intentions during the evaluation stage of the online consumer journey. The research further examines how these effects are moderated by the level of perceived risk. Main Research Question: How does the use of
