Löss-palaeosol-sekvensen (LPS) vid Velika Vrbica är belägen nära Donaus sydvästra strand i västra delen av den valakiska sänkan i Serbien. Sekvensens översta fem meter undersöktes med optiskt stimulerad luminiscensdatering (OSL) på kvarts och med magnetisk susceptibilitet (MS) varpå sedimentackumulationshastigheten (MAR) beräknades. Lagerföljden omfattar två enheter: en holocen jordmån (S0, 70
This thesis investigates how freedom of speech is implemented in a Swedish library context, by examining what actions and practices the concept is translated into at the Dawit Isaak Library in Malmö, a library focused on freedom of speech and banned literature that opened at Malmö City Archive in 2020. The aim of the study is to illuminate and clarify discrepancies between the theoretical definiti
The long-lasting usage of fossil fuels has brought its negative impact on the planet and thus the society is turning towards more environmentally sustainable solutions in every aspect of life. This master’s thesis discusses the novel topic of integrating concentrated solar thermal collectors, which directly produce steam, to drying processes in the food industry, which is proven to currently emit
This bachelor’s thesis is written by Emma Derwinger and Johanna Boman (2023), Division of Fashion Science Studies, Lund University. The study titled “Hellre medveten än hållbar?” aims to analyze and understand the use of traceability within the fashion- and textile industry and how relevant this tool of awareness is for consumers today. Approaching the topic, this paper focuses on an interview wit
The increasing urgency of climate change has raised the need for effective climate policy. The European Union emissions trading system (EU ETS) is the world’s first and largest ‘cap and trade’ policy which aims at reducing carbon dioxide emissions at the most cost-efficient allocation. The iron and steel industry is the largest emitter of carbon dioxide emissions in the Swedish industry sector. Ye
The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. It differs from a conventional heat pipe device in design and opera
Most (93%) of the greenhouse gas emissions in the transport sector come from road traffic in Sweden which includes passenger and freight transport activity (Trafikverket, 2022). The aim of this thesis was to understand pathways that transport purchasers can pursue to reach the fossil-free transportation goals from manufacturing plant to customer and to develop a process for assessing a market and
Den globala uppvärmningen är ett faktum. Stål är ett material som används i stor utsträckning och kan på grund av dess egenskaper inte alltid bytas ut mot alternativa material. Problemet är att stålindustrin står för en betydande del av Sveriges koldioxidutsläpp. Studiens syfte är att försöka skapa en uppfattning om de klimatvinster som kan göras om traditionellt stål ersätts av fossilfritt st
Mining operations have significant environmental and social impacts, including ecosystem fragmentation, biodiversity loss, pollution, and social issues such as low wages and unsafe working conditions. Despite these negative effects, mining plays a crucial role in the transition to low-carbon technologies and the demand for energy transition minerals is expected to surge. However, the potential per
The end of the Sri Lankan war was marked by a devastating loss of life, with hundreds of thousands of casualties. Amidst this tragedy, victims have claimed that the crimes committed against them constitute genocide, specifically targeting the Eelam Tamils solely because of their ethnic identity. However, denialists argue that there is insufficient evidence to support the presence of genocidal inte
Att med magi försöka locka åt sig ett objekt för sin kärlek är en företeelse som förekommit i många kulturer och Egypten under hellenistisk och romersk tid är inget undantag. Målet med detta arbete är att undersöka just denna typ av magi. För detta ändamål har jag valt att undersöka vad jag anser kan kallas för kärleksbesvärjelser i korpusen Papyri Graecae Magicae (PGM). De typer av texter jag u
I romersk litteratur förekommer en uppsjö av historier i vilka olika typer av andeväsen uppträder. Tre av de sorters andeväsen som dyker upp på ett flertal ställen i romersk litteratur och som kan kopplas till varandra är Manes, Lemures och Larvae. Målet med denna uppsats har varit att få en klarare bild av dessa andeväsens natur samt undersöka deras uppträdande i interaktioner med människor samt
Cities play a crucial role in mitigating climate change, yet reducing transportation emissions remains a challenge. Achieving decarbonization in the transportation sector requires systemic transformations across society. However, there is still a limited understanding of how transitions within transportation can be achieved, and further insight is needed to guide cities in driving transformative c
With an ongoing energy crisis in Europe and an ever-evolving political climate where the environmental impacts of industries are regarded as a top priority, the topic of energy efficiency is high on everyone’s agenda. Mathematical optimization of energy consumption requires a model of the problem at hand. In this thesis linear regression is compared with the gradient boosted trees method and a neu
This research focuses on synthesizing three cobalt complexes by ligands consisting of different conjugated systems and analysing their catalytic properties. These cobalt compounds are to be used to catalyse the reduction of protons generated in the reaction of water splitting. The reverse of water splitting is used in fuel cells and consists of oxidizing hydrogen gas to protons and electrons follo
The Swedish energy market is becoming more and more sustainable, with an increasing volume and number of diversified energy sources being continuously added to the mix. To stabilize the grid frequency, auctions are held to offer energy providers incentives to produce or consume energy on short notice. This paper is applying different multivariate time series models and their ensemble to find relia
There is growing pressure from stakeholders on global corporations to ensure the sustainability of their products throughout the supply chain. At the same time, due to the high complexity and dynamism of supply chains, companies often do not know what actors operate in their supply chains beyond direct suppliers. Supply chain visibility (SCV) and transparency (SCT) are crucial for ensuring respons
Livsmedelsindustrin har stor miljömässig påverkan och uppfyller inte de krav som ställs för att industrin ska betraktas som hållbar. Konsumenterna är en av de viktigaste intressenterna för att kunna implementera hållbar konsumtion. Genom att studera och analysera hur konsumenter skapar värde fås ökad förståelse för vad som driver hållbar konsumtion i livsmedelsindustrin ur konsumentperspektivet. S
