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

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Emelie Zhu; [2024]
    Keywords : Physics and Astronomy; Technology and Engineering;

    Abstract : 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. READ MORE

  3. 2. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  4. 3. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maja Holm; [2024]
    Keywords : Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

    Abstract : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. READ MORE

  5. 4. Estimating Diffusion Tensor Distributions With Neural Networks

    University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Author : Rimaz Nismi; [2024]
    Keywords : Diffusion; Magnetic Resonance Imaging; MRI; Neural Networks; Optimal transport; Earth mover s distance; Sinkhorn distance;

    Abstract : Magnetic Resonance Imaging (MRI) is an essential healthcare technology, with diffusion MRI being a specialized technique. Diffusion MRI exploits the inherent diffusion of water molecules within the human body to produce a high-resolution tissue image. An MRI image contains information about a 3D volume in space, composed of 3D units called voxels. READ MORE

  6. 5. Värdväxter hos Coleophora - säckmalar : koppling till utbredning och hotstatus

    University essay from SLU/Dept. of Ecology

    Author : David Lundgren; [2023]
    Keywords : värdväxter; insekter; nattfjärilar; säckmalar; Lepidoptera; Coleophora; lövminerare; småfjärilar; fjärilslarver; rödlistade arter; hotade arter; pollinerare;

    Abstract : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. READ MORE
