  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.

  3. 2. PREPARATION AND CHARACTERIZATION OF BOVINE MEAT AND MILK FACTOR VESICLES/PARTICLES & IDENTIFICATION OF MSBI1 REP INTERACTING PROTEINS

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Farhana Manzoor; [2020]
    Keywords : Bovine meat and milk factors; multiple sclerosis; immunoprecipitation co-immunoprecipitation; protein dimers; mass spectrometry; immunodetection; cesium chloride density gradient centrifugation; sodium dodecyl sulfate-polyacrylamide gel electrophoresis; vesicle; particle; interaction partner; pull-down assay.;

    Abstract : Introduction: Bovine meat and milk factors (BMMF) frequently isolated from bovine meat and milk, are discussed as putative causative agents for breast, colon and possibly other cancers. The hypothesis was formulated based on earlier correlative studies indicating that BMMFs could indirectly trigger inflammation, accumulate mutational events via reactive oxygen and nitrogen species production which eventually provokes tumor formation.

  4. 3. Lung Deposition of Airborne Particles - Resolved in a Single Breath

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Amalia Larsson Hurtig; [2020]
    Keywords : Aerosols; Airborne particles; Inhalation; Lung deposition; Respiratory tract deposition; Technology and Engineering;

    Abstract : Exposure to airborne particulate matter has been declared to cause cardiovascular and respiratory disease as well as cancer. By understanding how the aerosol particles deposit in our respiratory tract, we can understand how the exposure to airborne particles affect our health. READ MORE

  5. 4. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS

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

    Author : Alexander Ekman; [2019]
    Keywords : kaon; neutral kaon; K^0_L; K_Long; klong; single-particle response; response; detector response; calorimeter; ATLAS; CERN; jets; trigger level analysis; TLA; physics list; Monte Carlo; MC; Physics and Astronomy;

    Abstract : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. READ MORE

  6. 5. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Venkataramanan Mohandass; [2019]
    Keywords : Alloy 718; additive manufacturing; electron beam-powder bed fusion; surface engineering; shot peening; high temperature corrosion;

    Abstract : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. READ MORE
