  1. 1. Measuring copper abundances in the Galactic Bulge

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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.

  3. 2. Designing for Interactions in Learning Management System : An Evolution and Re-design of Canvas from a Student Perspective

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Alva Lundberg; [2023]
    Nyckelord :learning managment system; Canvas; interface; navigation; interactions;

    Sammanfattning : Learning management system (LMS) has been adopted by a majority of higher education institutions. LMS is an important tool for students in their education and often used daily by students in their studies. LÄS MER

  4. 3. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Saksham Jindal; [2022]
    Nyckelord :Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

    Sammanfattning : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

    Nyckelord :Thermal energy storage TES ; Thermochemical heat storage TCS ; SrCl2-NH3; Absorption; Desorption; Monoammine; Octaammine; Performance evaluation.; Termisk energilagring TES ; Termokemisk energilagring TCS ; SrCl2-NH3; Absorption; Desorption; Monoammin; Oktaammin; Utvärdering av prestanda.;

    Sammanfattning : This thesis is part of a joint thermochemical heat storage (TCS) research project named Neutrons for Heat Storage (NHS), involving three Nordic research institutes. The project isfunded by Nordforsk and KTH Royal Institute of Technology for the project partner KTH. LÄS MER

  7. 5. From the bulge region to the outer disk: Tracing the α-enhancement level in the Galactic thin and thick disks

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Elin Sandvik; [2020]
    Nyckelord :Chemical abundance; star formation rate; initial-mass function; APOGEE; Milky Way; Physics and Astronomy;

    Sammanfattning : One of the biggest mysteries astronomers wish to unveil is the formation and evolution of galaxies. Properties of our own galaxy, the Milky Way, can provide great insight into these. The star formation rate (SFR) and whether it varies with distance from the galactic centre (GC), is one of these properties. LÄS MER
