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

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

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

Mikrovågor på fotonnivå: Absorption och emission i kvantprickar I framtidens kvantsystem krävs teknik som kan detektera och generera extremt svaga ljussignaler. Här undersöker vi hur starkare interaktion mellan ljus (mikrovågsfotoner) och materia (elektroner) påverkar förmågan att effektivt detektera och generera sådana svaga ljussignaler. Kvantteknik är ett nytt spännande forskningsfält där detQuantum devices often operate with extremely weak microwave signals, necessitating highly efficient methods for microwave photon detection and emission. In this thesis, we investigate a device consisting of an InAs nanowire double quantum dot (DQD) coupled to a high impedance (2kΩ) SQUID array resonator. A high resonator impedance is expected to enhance the light-matter interactions between the re

This study examines the 1988 criminalization of personal drug use in Sweden by analyzing the developments in youth drug use between 1971 and 2024 and drug-related mortality between 1969 and 2017. Using a descriptive time-series approach and indexed graphs, it explores how these two indicators developed over time and whether their trajectories reflect the policy’s stated aim of reducing both use an

A case study of Ukrainian backlash towards Amnesty International’s report that raises a higher question of decentralization of communication in international NGOs The study contributes to the application and development of crisis communication response strategies during major communication scandals. It focuses on global NGOs with localized international representation. Local branches are identifi
