Green ammonia, produced from renewable hydrogen, is emerging as an important energy carrier and decarbonized fertilizer alternative. However, its production is highly energy-intensive, making process efficiency critical to its commercial viability. This study investigates how targeted heat integration can enhance the energy and cost efficiency of green ammonia production based on a 200 MW PEM elec
Since pre-industrial times, increased greenhouse gases in the atmosphere has contributed to climate change affecting all ecosystems. As a result, global and national commitments have been made to reduce emissions by enhancing the number and effectiveness of carbon sinks. To meet the national climate targets, Sweden has proposed financial compensation for forest owners who postpone harvesting. This
Purpose The purpose of this study is to describe and analyze the mining industry's driving forces, attractiveness and value network and propose strategic options for entry. Method This study’s method consists of a combination of a descriptive, exploratory and explanatory approach. The descriptive and exploratory approach is used at first to give a comprehensive picture of how the mining indust
Östra Tommarp is the name of a small village situated outside Simrishamn in eastern Skåne. Bioagro-life is an ongoing project sponsored by the EU. The main ambition is to eliminate carbon dioxide emissions from the process of heatproduction. The project will produce a more environmental friendly alternative to present use of burners with oil as fuel. The heating of the facilities within the villag
This master thesis addresses the electrically powered assisted bicycle (EPAC) as a future low-carbon commuting option and its market. The purpose of the report is to evaluate whether the EPAC can be used to improve the climate performance of the transport sector and to assess the outlook for the Swedish EPAC market. The EPAC is compared to the bicycle, car, bus and train and assessed thereafter. T
Global clothing consumption is increasing, with many garments having unnecessarily short lifetimes due to low quality materials and manufacturing, often linked to price pressures. Current European Union strategies focus on improving technical durability, product maintenance, and waste collection, but fail to address the role of the consumer for durable garments. A better understanding of drivers a
According to the UN Environment Programme, the construction sector is responsible for 37% of global energy and process-related CO₂ emissions. In Sweden, the latest data from Boverket – the Swedish National Board of Housing, Building and Planning – indicates that this sector accounts for 22.1% of the country's total greenhouse gas emissions. As part of national climate efforts, Fossilfritt Sver
Nanoparticles are an emerging threat to the environment. A major source is tyre wear particles (TWPs), with an estimated 6 million tons released into the environment globally each year. In Nordic countries, studded tyres used during the winter contribute to this pollution. This introduces a co-release of both tyre wear nanoparticles (TWNPs) and metal nanoparticles made of tungsten carbide cobalt (
Introduction: Enzyme-based approaches have shown promise in a more targeted alternative for treating oral diseases such as caries. Given the high global prevalence of caries, and ecological complexity of the oral microbiome, investigating selective treatment strategies is of significant interest. Background: The oral microbiome is a dynamic, polymicrobial community, dependent on ecological balance
The second wave women’s movement in the 1970s was global and many organized for better healthcare, against the exploitation of women’s bodies and for women’s liberation. In Sweden the largest and most visible group within the second wave women’s movement was Grupp 8. They existed in several cities and places in the country and out of all the local groups within Grupp 8, nine were donated to differ
Background: Poor self-reported sleep quality is associated with cognitive impairment. Alzheimer’s disease (AD) patients present sleep disruptions decades before they start to decline clinically. Similarly, amyloid-β (Aβ) starts accumulating during the preclinical phase of the disease. This study investigated associations between self-reported sleep quality and Aβ burden longitudinally in clinicall
Purpose: The persistent congestion and prolonged waiting times of trucks at maritime container terminals undermine port performance and supply chain efficiency. Ensuring smooth truck flows is essential for ports to fulfill their economic and social roles in global trade, creating significant pressure on operators to deliver reliable service. To support these efforts, it is crucial to identify
We considered the phase coherence dynamics in a Two-Frequency and Two-Coupling (TFTC) model of coupled oscillators, where coupling strength and natural oscillator frequencies for individual oscillators may assume one of two values (positive/negative). The bimodal distributions for the coupling strengths and frequencies are either correlated or uncorrelated. To study how correlation affects phase c
Background: Due to demographic changes and a strained public sector operating in many countries globally, informal care is increasing. Currently, at least 1.3 million adults in Sweden regularly provide help, support and/or care to a family member/significant other. With no sign of an imminent decrease in their caring activities, it is important that informal carers are considered as a key stakehol
Patients with coronary artery disease remain at increased risk of recurrent life-threatening cardiovascular events even after adequate guideline-based treatment of conventional risk factors, including blood lipid levels. Inflammation is a critical pathway in the pathogenesis of atherosclerosis and is independently associated with risk of recurrent cardiovascular events. Leukotrienes are potent pro
Background: The effect of change in hip anatomy on change in gait pattern is not well described in current literature. Therefore, our primary aim was to describe and quantify changes in hip geometry and gait pattern 1 year after total hip arthroplasty (THA) in individuals with hip osteoarthritis. Our secondary aim was to explore the effect of postoperative change in femoral neck anteversion (FNA)
