When acidification of soils and lakes got acknowledged in the 1960’s, it soon became one of the biggest environmental issues in northern Europe. Long-range transport of sulphur and nitrogen emissions caused acid rain to fall thousands of kilometers away from its source. South-western Sweden was one of the areas most affected by acidification. One of the lakes affected is Lake Gårdsjön, situated ab
Surface water fluctuations and lake storage has been severely impacted by climate change, causing severe flooding and drought events. Hence, monitoring the storage of lakes and reservoirs is of paramount importance to assess freshwater availability, to maintain a balance with the ecosystem and water use. This balance is important for sustainable water management in Sweden, which is reflected in th
Detta examensarbete undersöker hur de uppdaterade kriterierna i certifieringssystemet Miljöbyggnad påverkar hållbarhetsmålen inom bygg- och fastighetssektorn. Arbetet utgår från den centrala problematiken att byggsektorn är en av de största källorna till utsläpp och negativ miljöpåverkan. Miljöcertifieringssystem har potentialen att minska den negativa miljöpåverkan inom bygg- och fastighetssektorThis thesis examines how the updated criteria in the Miljöbyggnad certification system affect sustainability goals in the construction and real estate sector. The work is based on that the construction sector is one of the largest sources of emissions and negative environmental impact. Environmental assessment methods have the potential to reduce the negative environmental impact of the constructi
Additiv tillverkning (AM), vanligtvis kallad 3D-utskrift, erkänns som en transformativ metod inom modern tillverkning. Tekniken möjliggör framställning av komplexa geometrier med ökad materialeffektivitet, lokaliserad produktion och större designfrihet. Trots dessa fördelar kvarstår utmaningar när det gäller att optimera AM-processer för att säkerställa resurseffektivitet – särskilt i att minska mAdditive Manufacturing (AM), commonly referred to as 3D printing, has known as a transformative approach in modern manufacturing. It enables the production of complex geometries with reduced material usage, localized fabrication, and improved design flexibility. Despite these advantages, challenges remain in optimizing AM processes to ensure resource efficiency, particularly in minimizing material
To reduce reliance on energy-intensive, chemically synthesised nitrogen sources in microbial cultivation, we investigated the integration of the nitrogen-fixing bacterium Azotobacter vinelandii into a bioconversion process with the recombinant yeast Saccharomyces cerevisiae. Our objective was to develop a more sustainable approach by utilising biological nitrogen fixation to supply ammonium direct
This thesis explores the potential of soundscape-based urban design to activate and regenerate Norra Grängesbergsgatan (NGBG), a post-industrial corridor in Malmö, Sweden. Rather than treating sound as a byproduct of urban life, the project positions it as a primary design medium one that can shape spatial experiences, encourage social interaction, and support cultural identity. The design introdu
Straumann® Emdogain® is a protein-based gel used in dentistry for tissue regeneration. Emdogain® contains enamel matrix proteins, which are mainly amelogenin proteins. These are obtained through weakly acidic extraction from porcine tooth buds. Embedded in the enamel matrix is also hydroxyapatite which releases calcium ions. These ions saturate the solution, and the protein extraction halts. An at
According to the Intergovernmental Panel on Climate Change (IPCC), atmospheric methane (CH4) concentrations are considered a crucial factor in global warming, particularly in the near term, due to its high warming potential (~ 80 times more potent than carbon dioxide, or CO2) and shorter atmospheric lifetime compared to CO2. CH4 emissions have more than doubled since the industrial revolution and
Denna kandidatuppsats beskriver utvecklingen av en bättre modell för att uppskatta den elektriska styrenhetens, (Electrical Control Unit), ECU-strömmen, i ett Gen VI ställdon, vilket används i moderna fyrhjulsdrivna fordon. Projektet genomfördes i samarbete med BorgWarner och är baserat på laboratorietester och elektriska simuleringar. Målet med modellen är att förbättra hur exakt ECU-strömmen uppThis bachelor's thesis describes the development of a better model to estimate the Electrical Control Unit, ECU current in a Gen VI actuator, which is used in modern all-wheel-drive vehicles. The project was done in collaboration with BorgWarner and is based on lab tests and electrical simulations. The goal of the model is to improve how accurately the ECU current is estimated. This is importa
Syftet med denna studie var att undersöka effekterna av flotation-REST (Restricted Environmental Stimulation Therapy, en sensoriskt reducerad avslappningsmetod) jämfört med passiv vila med lugnande musik på den subjektiva upplevelsen av fysisk ansträngning, mätt direkt efter högintensiv fysisk aktivitet. Fyrtiofyra deltagare (18 idrottare och 26 icke-idrottare) genomgick båda återhämtningsmetodernThis study aimed to examine the effects of flotation-REST (Restricted Environmental Stimulation Therapy) as sensory-reduced relaxation method in comparison to passive rest with relaxing music, on the subjective experience of perceived physical exertion measured immediately after high-intensity exercise. Forty-four participants (18 athletes and 26 non-athletes) experienced both recovery methods in
Carbon capture utilization and storage (CCUS) is set to play a key role in decarbonization. Most of the technologies are yet to be seen on commercial scale. Denmark is in the process of establishing some of the first large-scale CCUS value-chains. Through a combination of document analysis and interviews, I study the ideas driving the current roll-out of CCUS in Denmark. To do this, I make use of
This study aims to examine the experience of international students from Lund and Malmö universities regarding social participation and loneliness throughout their studies abroad. I conducted qualitative interviews with international students from the universities. After I gathered my empirical data, I then assessed their experiences through Goffman’s stigma theory and Antonovsky’s sense of cohere
Denna uppsats undersöker hur riskanalysmetoder inom flygindustrin kan förstås och utvecklas utifrån ett Safety II-perspektiv. Traditionellt har metoder som riskmatriser, Aviation Risk Management Solution (ARMS) och Bowtie fokuserat på att identifiera och hantera negativa händelser (Safety I). Perspektivet som kallas Safety-II introducerar ett kompletterande synsätt där fokus ligger på att förstå v
Products made from pulp are a part of everyday life. With end products like coffee filters, food packaging and tissue paper. These products are the result of wood being processed in pulp mills to produce the pulp from which the forementioned paper products are produced. The modern pulp and paper industry is energy intense and on a global perspective a large emitter of greenhouse gasses, accounting
The study investigates the relationship between drinking water quality and birth outcomes in Colombia, focusing on early neonatal mortality and low birth weight. Using nationally representative Demographic and Health Survey data, the study combines logistic, multilevel and spatial analysis to assess individual-level and geographic determinants of neonatal health. The results show that mothers expo
The increasing integration of AI-generated microcontent summaries in everyday use lacks clear evidence of impact on user decision quality compared to simpler methods or original content, raising "AI-washing" concerns. This study empirically investigated the effects of AI-generated summaries of microcontent on user decision quality, considering content collection length, to assess if and
