Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser. Detta kräver en övergång till​​The consumption of plastic has significantly increased over time and has emerged as a vital material in contemporary society, primarily derived from fossil fuels. Use of plastic aligns with the linear economy of “take, make, dispose”, which contributes to mishandling of plastic waste and an ineffective use of resources. This calls for a shift towards a circular economy, advocating for the princi

Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. This project investigated the geometrical accuracy of Radixact

Fermentation has played a vital role in human history, offering solutions for food preservation, culinary diversity, and the creation of diverse and flavorful foods and beverages. Its importance continues today, both in traditional practices and in modern industrial applications. This report outlines the outcomes of an investigation into and the optimization of the solid-state fermentation proces

In the capitalist system, there is a need to envision alternatives that advocate for a more just and sustainable world. Alternative scholarships, such as degrowth, aim to counter the hegemonic narrative of food commodification by promoting practices that put social and environmental well-being at the forefront. This ethnographic research outlines the alternative strategies of tackling food waste a

This study investigates the experiences of individuals who have left a criminal lifestyle and the factors influencing their journey. Through interviews with both individuals active in a criminal lifestyle and those who have successfully transitioned to a law-abiding life, this research explores the motivations for leaving a criminal lifestyle and the challenges faced during this process. Key findi

The Bangladeshi Gen Zs and university students demonstrated a revolutionary example of civic engagement, participatory culture, subcultural identity formation, and reformation during the Student Quota Reform Movement in July, leading to the July massacre where thousands of protesting students were tortured and shot to death in public. The movement happened as an enraged response against the announ

As the COVID-19 pandemic spread across the globe, unprecedented policy measures were implemented by central banks and governments to dampen the effect on the real economy. Alongside the spread of the pandemic, research regarding how to simulate similar effects of the virus on the real economy and how to formulate optimal policy began spreading at an equal pace. The aim of this thesis is twofold. I

The most common controller in the process industry today is the PID controller due to its simple structure. A regular factory may have thousands of different PID controllers in use where each of them has to be tuned to work satisfactory. Doing this manually can become both a difficult and time consuming task where some knowledge for each process is required. Therefore, it is highly beneficial to h

Three-dimensional (3D) city models are increasingly utilized among stakeholders of different sectors, particularly those dealing with building information. 3D city models are a three-dimensional digital representation of urban structures, most prominently buildings. They offer diverse applications and have gained wide acceptance as a support tool in planning practices. The push to achieve greater

The covid pandemic has put light on a trend of office buildings experiencing more vacancy than ever before, given our working habits have been forced to shift from occurring predominantly in an office to mainly being pursued from our private homes. This project foresees a future where working remotely has become the new normal and proposes a residential program in an existing office structure, giv

Hematopoietic stem cells (HSCs) are of great importance for the body and can be used to treat diseases such as leukemia or autoimmune conditions. To be able to use HSCs more extensively in therapies we need to know more about how they are being regulated, one way to do this is by knocking down genes with RNA interference. In this project we test a new micro RNA (miRNA), called miR30E, to investiga

In response to growing social injustices in cities, bottom-up initiatives are increasingly recognised as sites of resistance and experimentation. I examine how the PARKS project in Hamburg, a temporary, collectively governed green space, challenges neoliberal urban development and envisions socially just green spaces. Adopting a case study approach, I draw on semi-structured interviews, participan

The increase in contact resistance within battery systems remains poorly understood, despite being one of the primary contributors to battery degradation. This project aims to investigate this phenomenon by modeling the electrical interface as a contact between a pin and a busbar. The main goal is to build a DOE and machine learning framework, using Bayesian optimization to efficiently explore the

The aim of this thesis has been to investigate the legal conditions and process for triggering Credit Default Swaps, which are derivative instruments to shift credit risk exposure between parties in an underlying financial instrument. The condition is called credit event and a case study has been done on the Greek credit event in 2012. The thesis shows that there is a clear and robust framework o

This essay addresses the needs of so called ‘climate migrants’. It focuses exclusively on the relocation of the population of Kiribati, a small island nation in the Pacific Ocean whose very existence is threatened by the effects of climate change. With the principles of causality, morality, capacity and community, Miller’s Connection Theory provides the study with a framework for discussing the di

Bakgrund: Höga ljudnivåer och bullerskador är ett vanligt problem på arbetsplatser. Många väljer att inte använda hörselskydd då de upplevs försvåra kommunikation. En metod som med ett enkelt mått kan utvärdera hörselskydds påverkan av taluppfattning vore värdefullt. Syfte: Syftet med studien var att undersöka möjligheten att med metoden Speech intelligibility impact Level (SiimpL) mäta skillnad m

In this paper, we investigate evidence of market discipline from contingent convertible (CoCo) issues. Previous research has focused on the monitoring aspect of market discipline, by testing risk sensitivity of market prices (subordinated notes and debentures (SND)) to accounting measures of bank risk. We take a similar approach using CoCo spreads and additionally use issue specific features. We a
