Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term. Furthermore, water scarcity poses a critical challenge for Kenya, particularly i
The carbon intensity is an important metric that provides a clear measure of the environmental impact associated with the electricity use. Carbon intensity of electricity use is differentiated into CO₂ equivalents per kilowatt-hour, which standardises the measurement by expressing the emissions of various greenhouse gases in terms of the equivalent amount of CO₂ based on their global warming poten
Denna rapport utforskar konceptet undvikna utsläpp, även kallat Scope 4-utsläpp, som en del av företags hållbarhetsrapportering- och kommunikation. Med fokus på PowerCell Group, en leverantör av vätgasdrivna bränsleceller, undersöker studien hur Scope 4-utsläpp kan integreras i hållbarhetsrapportering och vilka möjligheter och utmaningar detta innebär. Undvikna utsläpp refererar till de minskningThis thesis explores the concept of Scope 4 emissions, also known as avoided emissions, within corporate sustainability reporting. With a focus on PowerCell Group, a provider of hydrogen fuel cell solutions, this study investigates the integration of avoided emissions reporting, assessing both the potential benefits and the challenges associated with this practice. Avoided emissions refer to redu
The purpose of the thesis was to study the safety and reliability requirements in the automotive industry from a production test perspective. A survey of the requirements in the automotive standard AEC-Q100 was conducted and the implications of compliance with the requirements were analyzed. In addition to this, production data was reanalyzed considering the requirements found in the survey. From
In any storage ring or synchrotron based light source one of the most important factors for generating light with desirable properties is the electron beam itself. The dynamics of the beam must be properly characterised and, ideally, adjusted to the desired values for the light source to be able to deliver radiation of the quality which was decided during its design. This thesis is limited to som
Our world is experiencing accelerated ecological destruction and social injustices on different scales and multiple levels. Unchecked economic growth has been criticised as causing this since the 1970s, but the dominant sustainable development paradigm has perpetuated the belief that economic growth and environmental protection can go hand-in-hand. In response degrowth has emerged in the last deca
Introduction: This study is focused on the development and comparison of different extraction methods for vitamin D (VD) analysis in liver samples. Background: VD deficiency is related to several diseases, so it is crucial to correctly detect and quantify its concentration in the human body. Despite the existing methodologies for VD analysis, the selectivity and the sensitivity of the methods for
The impact that anthropogenic micropollutants have on the environment is increasingly gaining attention. As a result of this, Sweden, among other countries, is looking towards implementing advanced treatment for micropollutant and pharmaceutical product removal from wastewater prior to discharge into the environment. The leading method to achieve this is ozonation, which unfortunately also creates
Eftersom människor tillbringar större delen av sin dagliga tid inomhus idag, ökar intresset och användningen av system för inomhusmiljöer, så kallade inomhuspositioneringssystem (IPS). De senaste åren har det därför tillkommit nya dataformat för inomhuskartläggning och kommersiella IPS och har ännu inte studerats ingående. Därför ger rapporten en översikt över huvuddelarna i IPS: dataformat för inAs people spend most of their daily time indoor today, the interest and usage of systems for indoor environments, called indoor positioning systems (IPSs), are increasing. The last couple of years, new data formats for indoor mapping and commercial IPSs have been released and they are not yet extensively studied. Hence, this thesis provides an overview of the main parts of IPSs: data formats for i
This thesis is a field study which was conducted for 10 weeks in the regional capital city of Casamance named Ziguinchor in Senegal. By using tools from feminist critical theory and methodology such as participatory observations and feminist in-depth interviews with women organisations in Ziguinchor, the purpose of the thesis is to understand how gender roles affect women and women organisations s
The aim of this thesis work was to investigate and evaluate new possible industrial applications for large welded plate heat exchangers, with heat transfer areas of at least 500 m2. The research has been carried out through thermal design of heat exchangers for a total of nine cases. The nine cases are real-life applications for processes covering the petrochemical, oil & gas, power, and refin
Nutrient recovered faecal sludge is a novel alternative fertilizer product, and is proposed to be promoted in places where improvement in sanitation management is needed, for example in Uganda’s capital Kampala. However, Uganda and most of Africa is perceived as a faecofobic area, i.e. where faeces are stigmatized and guarded by taboos, and there is lacking information regarding Ugandan farmers’ p
Sierra Leone struggles with one of the world’s highest rates of teenage pregnancy. Reducing the rate of teenage pregnancy and ensuring access to education for all are key to achieving gender equality and empowering women and girls. This is not only a top priority for the government but also an essential part of ensuring the human rights of the population and achieving inclusive development, as rec
Parental leave policies for fathers are introduced to promote father’s caregiving and gender equality in childcare. Even though the majority of father-friendly policy reforms were led by social democratic parties, a few conservative catch-all parties also proposed policies to promote father’s caregiving. How did conservative catch-all parties frame father’s caregiving when they propose policy refo
Due to human-induced environmental changes, many natural populations are undergoing extensive fitness declines. Natural or sexual selection could potentially shift the phenotypic mean of critical traits towards new phenotypic optima, promoting evolutionary rescue. However, this process has rarely been studied in natural populations. Furthermore, the population fitness can also be increased by gene
This thesis presents the development and evaluation of a virtual reality (VR) environment designed for integrated EEG, EMG, and joint movement data collection. The system combines immersive VR with biosignal acquisition technologies, including the Unicorn Hybrid Black EEG, the Myo Armband for electromyography and inertial sensing, and the Cyberglove for hand joint tracking. The goal was to create
Children with bone marrow failure syndromes and severe aplastic anemia (SAA) are treated with allogeneic blood or marrow transplantation (BMT). However, there is a paucity of studies examining late mortality risk after allogeneic BMT performed in childhood for bone marrow failure syndromes and SAA and evaluating how this risk differs between these diseases. We investigated cause-specific late mort
This work investigates the stability of emulsions prepared by using octenyl succinic anhydride (OSA)-modified waxy maize starch in the form of granules, dissolved starch, and non-solvent precipitated starch as Pickering emulsion stabilisers. The aim of this study was to investigate the effects of different forms of starches on the stability of emulsion using light microscopy, light scattering, and
