Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot

More than half of the world's population today lives in urban areas, and the relationship between the city and the sea has always played a central role. Studies show that access to waterfront environments in port cities historically been limited, but as urban development progresses, the coastline is gaining increasing significance in the urban context. This presents both opportunities and chal

Background: Estrogen receptor alpha (ERα) is a protein that belongs to the nuclear receptor family. It is regulating the expression of genes involved in cell cycle progression, proliferation, and apoptosis. Approximately 75% of breast cancers express ERα, making it an important target for treatment. Researchers have identified various isoforms of ERα, with the most well-characterized one being a 6

This thesis investigates how AI-generated music challenges traditional systems of cultural legitimacy, identity, and musical taste. Drawing on Bourdieu’s theory of cultural fields and symbolic capital, and supplemented by Simon Frith’s insights into authenticity and identity performance, the study examines how emerging technologies reconfigure creative authority within platform-driven environments

Sjögräs förändrar kemin under sig – betydelse för havets skogar att ta upp koldioxid Sjögräsängars betydelse för såväl den lokala vattenkemin som den globala koldioxidbalansen är väl känd, och de kallas ofta för havets skogar på grund av deras höga produktivitet och förmåga att lagra kol från atmosfären. Vad som dock händer under botten, i porvattnet bland sjögräsets rötter och dess associerade mSeagrass systems are integral components of both local and global carbon cycles and contribute to substantial modifications of seawater biogeochemistry which has ecological ramifications. However, the influence of the roots and rhizomes of seagrasses on surrounding porewater biogeochemistry is not fully understood, and it remains to be determined what exact role this marine plant and the associate

This study charts the possibilities of recycled plastic and its use as an alternative building material for low-income housing in Colombia. The building materials in the study have been compared with respect to their physical properties, the cost and how they affect the indoor climate in each building. Colombia is a country that has been subjected to civil war for many years, which has contribute

Water management tackles complexities within the interconnected social, political, economic and ecological systems across scales, while aiming to meet the needs of multiple stakeholders dependent on water. Many tensions and unsolved issues persist in water management regarding socio-political power structures, spatial scale, and relations between stakeholders who have different perceptions on prob

It can no longer be refuted that greywater reuse is paramount to curbing the persistent global water crisis. Of the domestic wastewaters, greywater is less polluted than blackwater, but treatment is still necessary to make it safe for reuse. The most common greywater reuse application is toilet flushing. However, the use of vacuum toilets in the Oceanhamnen project, covered in this thesis, means t

Antibiotika är en av de viktigaste upptäckterna under 1900-talet. Med antibiotika blev det möjligt att bekämpa och förhindra bakteriella infektioner. Ett växande och svårlöst problem är antibiotikaresistans. Detta projekt syftar till att hitta alternativ till klassisk antibiotika. Vi har arbetat med sialinsyra, en kolhydrat som återfinns på cellytan. De flesta bakterier tillverkar inte själva siaThe development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl

Att dika skogar till förmån för bland annat bättre tillväxt kan påverka och förändra faktorer som marktemperatur och markfuktighet vilka är de viktigaste faktorerna för markrespirationen och flödet av koldioxid till atmosfären. Markrespirationen svarar för huvuddelen av koldioxidflödet till atmosfären från ett markbundet ekosystem. Koldioxid är en viktig växthusgas och små förändringar av flödet kDitching forests in favor of for example better tree growth can affect and change factors such as soil temperature and soil moisture. Those are the most important factors for soil respiration and the flow of carbon dioxide (CO2) into the atmosphere. The soil respiration accounts for the major flux of CO2 to the atmosphere from the terrestrial ecosystem. CO2 is an important greenhouse gas and small

Grönlands inlandsis utgör världens näst största färskvattensreservoar. Forskning har visat att Grönlands inlandsis förlorar mer och mer massa, vilket också bidrar till den stigande havsnivån, i kombination med andra faktorer. Avrinningen förväntas också öka i framtiden på grund av den globala uppvärmningen. Hur mycket massa som lämnar Grönlands inlandsis beror på den totala massbalansen. Den totalThe Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. Surface mass balance (SMB) plus the dynamic mass losses fr

Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. Thanks to 42 new 10Be exposure ages, the timing of the stabilisation of selected moraines was constrained. The application

The study, conducted in cooperation with Eolus, takes place in Anneberg, Sweden, home to three wind turbines with a combined capacity of 10.8 MW. This study examines whether or not it would be profitable to integrate an additional intermittent power source to the wind power plant’s existin

Recruitment of new individuals is essential for a population to survive and flourish and bladderwrack (Fucus vesiculosus) is on the decline in some parts of the Baltic Sea. The causes being multitude and complex, culminating to the loss of light penetration being the main culprit. As society moves forward, artificial submerged structures may serve as new footholds for a waning population as well a

The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th

When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. It is currently a manual process where points from a virtual environment are transferred to

With the global population projected to reach eight billion by 2022, the world faces significant challenges associated with rapid urbanization. The migration of individuals from rural to urban areas in search of improved opportunities exacerbates the strain on resources, posing obstacles such as housing shortages, infrastructure demands, and food scarcity in growing cities.
