  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  3. 2. Drivers of sea level variability using neural networks

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Linn Carlstedt; [2023-05-10]
    Nyckelord :;

    Sammanfattning : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

  4. 3. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  5. 4. RAINWATER HARVESTING FROM ROOF TOPS IN URBAN AREAS: QUANTITY, QUALITY AND ENVIRONMENTAL BENEFIT : Case studies in Sweden and Colombia

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Sonny Colin; Michael Erneland; [2023]
    Nyckelord :3D-printing; Hydrological cycle; Low-cost sensors; Water scarcity; Water shortage; Water supply; Water quality; Water quality Index; Water quantity;

    Sammanfattning : This study has looked at two separate locations, Malmö in Sweden, and Medellin in Colombia, and what the possibilities of rainwater harvesting are in those locations. The paper investigated data gathered by low-cost sensors in Malmö region, as well as sampling and measurements of rainwater collected in Malmö and Medellin, analysed by laboratories in both countries.

  7. 5. A Simulation-Based Decision Support Tool for Circularity : Remanufacturing of an Electric Machine Case Study

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Mayari Pérez Tay; [2023]
    Nyckelord :Simulation; remanufacturing; circular business; electric machine;

    Sammanfattning : Over the last years, environmental concerns have grown regarding the pressure manufacturing activities exerts on natural resources. Many materials have been classified by the EU as scarce, rare earth elements found in magnets are amongst critical materials with high supply risk. LÄS MER
