    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Monika Böttcher; [2024-03-19]
    Keywords : Golden sand bee; Andrena marginata; Devil´s bit scabious; Succisa pratensis; Oligolectic bees; Inventory; Meadow land; Conservation;

    Abstract : Over a decade ago, a conservation project aimed at preserving the endangered golden sand bee (Andrena marginata) populations in the Storån valley of the municipality of Marks was initiated. The species, red-listed in Sweden as well as in many other European country, specializes in pollen from Devil's bit. READ MORE

  3. 2. Development of ultra-sensitive immunoassay on Gyrolab microfluidic platform using Binding Oligo Ladder Detection : Enhancing Gyrolab biomarker assays using Exazym®

    University essay from Uppsala universitet/Institutionen för farmaci

    Author : Sam Vadi Dris; [2024]
    Keywords : Immnoassay; Gyrolab; TNF-alpha; Ultra-sensitive; Cavidi; Exazym; BOLD amplification; Amplification;

    Abstract : Immunoassays are widely used for detection of antigens in a wide range of applications including assays in pharmaceutical development. Immunoassays are continuously improved in many aspects including automatization, miniaturization and extending the dynamic range. READ MORE

  4. 3. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  5. 4. Navigating the Waves of Conservation: Spatiotemporal Patterns in Harbour Porpoise Strandings in Swedish Waters

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Vigge Ulfsson; [2024]
    Keywords : Strandings; spatiotemporal patterns; harbour porpoise;

    Abstract : Harbour porpoises (Phocoena phocoena) are the only cetacean residents found year-round in Swedish waters. Since in situ monitoring of cetaceans can be difficult, invasive and often costly, strandings can be used as a cost-effective alternative to continuously collect data on these elusive animals.

  6. 5. 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.
