The rise in global emissions of carbon dioxide and the need for new technologies to combat climate change has prompted extensive research into carbon capture methods. This master thesis focuses on a novel carbon capture absorption technology, developed at Lund University, that utilizes the amine 2-amino-2-methyl-1-propanol (AMP) in the organic solvent dimethyl sulfoxide (DMSO) to capture CO2. A ch

This thesis aims to understand the exclusionary process that leads women to be underrepresented in the renewable energy industry in Sweden. Through interviews and a ground theory approach to the analysis of the data, this thesis aims to explore the perception and experiences of women during their higher education in heavy math STEM careers and later their career choices this thesis will provide an

The recent advent of 3DSG in the computer vision domain has brought powerful high-level representations of 3D environments. These representations strive to mimic human perception and facilitate the extraction of meaningful insight from visual data. This research has led to framework like Hydra, which creates a real-time, persistent spatial perception system that creates a complete 3D map of their

Food production is a major driver of climate change and environmental degradation. There is a political will to use public procurement as a strategic tool to promote more sustainable practices in the food industry. There are many aspects of sustainable food consumption, and one aspect that is getting increased attention is locally produced food. This study aims to examine how municipalities in the

This thesis explores the concept of “meanwhile use” in the context of the Tolka Quay area of Dublin. The project proposes a temporary use of the underutilized space to activate it and contribute to the area’s long-term development. Through five phases of design, which are Connection, Landscape, Zoning, Building, and Future, the project aims to create a vibrant and sustainable community hub in Tolk

Den globala klimatkrisen innebär betydande sociala utmaningar och hotar biologisk mångfald. Klimatförändringar ökar sårbarheten i kustområden, vilket leder till ökad erosion och översvämningar. Naturbaserade lösningar (NbS) erbjuder en mångfacetterad metod för att adressera dessa problem. Denna masteruppsats granskar användningen av NbS för kustskydd i Bjärred, i södra Sverige, och kommunens stratThe global climate crisis presents significant social challenges and threatens biodiversity. Climate change is increasing the vulnerability of coastal areas, leading to more erosion and flooding. Nature-based solutions (NbS) offer a multifaceted approach to address these issues. This thesis examines the use of NbS for coastal protection in Bjärred, southern Sweden, and the municipality's strat

A growing field of research links natural environments to increased human well-being. These benefits are especially valuable for people in the process of regaining health, for instance those who are in hospitals. Through reviewing planning documents and interviewing key actors, this thesis explores how natural environments are incorporated in the planning of a future hospital in Helsingborg, Swede

Syftet med den här studien är att visa att den myndigheten som studeras är en rationell byråkratisk organisation som disciplinerar sina medarbetare till fogliga anställda som kan kontrolleras och övervakas. Nyckelord i studien är byråkrati, beteende och disciplinering. Det är en kvalitativ studie som använder sig av observationer och intervjuer för insamling av empiriska materialet. Observationen

I dagens samhälle förbrukar vi naturresurser på ett helt ohållbart sätt. Vi producerar och konsumerar i så hög fart att naturen inte hinner återskapa de resurser vi gör av med. Det behövs en samhällsutveckling i en mer hållbar riktning, där vi går från en slit-och-släng-mentalitet till att tänka cirkulärt. Byggbranschen förbrukar stora mängder resurser, genererar enorma utsläpp av växthusgaser och

Abstract The task of the thesis is to study what is required to be self-sufficient in the countryside in order to in turn see what is possible with today's real estate legislation and other legislation that affects the area. A primitive degree of self-sufficiency is chosen in order to examine the legislation as thoroughly as possible. The study puts forward proposals, in order to facilitate se

This case study of the satire conspiracy theory phenomenon Birds aren’t real, aims to contribute to the academic field of conspiracy theories. Conspiracy theories have seen a rising interest in academia in the last decade. Negative outcomes of the rapid spread of conspiracy theories and misinformation are a threat to democratic struc-tures, institutions, and values. Although the societal importanc

This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. The different ratios were 100% sucrose; 100% maltodextrin; 50% ma

This thesis presents a method, based on feedback linearization, for controlling a general 3-degree-of-freedom simulation model of an aircraft. Only aircraft models that utilize Taylor approximations of the aerodynamic coefficients are considered. The intent is to be able to simulate the same mission with different aircraft models without having to tune the control system specifically for each mode

The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. Detrimental effects of competition can result where co-existing species exhibit a high degree of shared resource use (i.e., niche overlap). Th

Weather extremes, such as extreme heat and precipitation, are expected to increase in both intensity and duration due to climate change. Previous research suggests members of the acute homeless population are particularly vulnerable to such climatic extreme events. However, this has not been studied earlier in the context of Sweden. In this thesis, I merge the two persistent global problems, weath

På grund av energiomställningen, Sveriges mål om att ha en fossilfri elproduktion 2040 samt målet om nettonollutsläpp av växthusgaser 2045 förväntas en omfattande utbyggnad av förnybara energikällor ske. I denna rapport har därför elbehovet, potentialen för elproduktion, möjliga framtida systemproblem samt lösningar undersökts. Efter en omfattande litteraturstudie har det framkommit att elbehove

The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. The lignin was then c

In 2021, the Icelandic government stated that Iceland will implement an energy transition plan with the goal of becoming a 100% carbon neutral and fossil free nation by 2040, furthermore, that a doubling in renewable energy production was needed to reach that goal. This led to an upsurge of a discourse among stakeholders and concerned citizens about the future of Iceland. This thesis is an attempt
