  1. 11. WHAT ARE THE CHARACTERISTICS OF AIRBORNE PARTICLES THAT WE ARE EXPOSED TO? Focus on Indoor Environments and Emissions from Biomass Fired District Heating

    Författare :Aneta Wierzbicka; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particles; indoor environments; biomass combustion;

    Sammanfattning : Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. LÄS MER

    Sammanfattning : Humans are exposed to metals and metal-containing materials daily, either conscious, e.g. using metal tools or objects, or unconscious, e.g. LÄS MER

  5. 14. Search for New Scalar Particles with ATLAS

    Författare :Stefio Yosse Andrean; Christophe Clement; Sara Strandberg; Markus Klute; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Large Hadron Collider; ATLAS; Standard Model; Higgs; supersymmetry; calorimeter; Physics; fysik;

    Sammanfattning : The Large Hadron Collider (LHC) is currently the most powerful particle accelerator ever built. It accelerates protons and collides them at the center of mass energy of √s = 13 TeV. LÄS MER

  7. 15. Transition in Particle-laden Flows

    Författare :Joy Klinkenberg; Luca Brandt; Shuisheng He; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; multi-phase flow; particle-laden; heavy particles; light particles;

    Sammanfattning : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. LÄS MER
