  1. 1. Test setup for LDMX HCal readout

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

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  2. 2. Throughflow Study on Bleeding for Part Load Compressor Operation

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Hedkvist; [2019]
    Keywords : Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

    Abstract : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. READ MORE

  3. 3. Detailed chemical abundances of neutron-capture elements - from 523 local giant stars

    University essay from Lunds universitet/Astronomi

    Author : Rebecca Forsberg; [2019]
    Keywords : The Milky Way galaxy; Abundances; High-resolution spectroscopy; Neutron-capture elements; Physics and Astronomy;

    Abstract : Purpose: The purpose of this work is to determine the abundances of neutron-capture elements in solar neighborhood giant stars. This enables constraints to be put on the the cosmic origin of these elements. READ MORE

  4. 4. Leaching of Glass Waste – Structure and Humidity Cell Tests

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elin Sandgren; [2019]
    Keywords : Glass structure; glass leaching; glass modifiers; humidity cell test; saturation index; arsenic; lead.; Glasstruktur; lakning av glas; glasmodifierare; fuktkammarförsök; mättnadsindex; arsenik; bly.;

    Abstract : Glass production has historically occurred at around 50 glassworks in Sweden, in a region known as the Kingdom of Crystals (Glasriket). Today, most of these sites are no longer active and left behind is glass waste of different forms (both as fragments of finished glass as well as unrefined glass melts). READ MORE

  5. 5. Detailed analysis of the chemical composition of stars harboring Earth-like planets

    University essay from Lunds universitet/Astronomi

    Author : Lorena Acuña Aguirre; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. READ MORE
