  2. 1. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

    Author : Göran Frank; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; unipolar charger; Physics; DMA; differential mobility analyser; DAA; droplet aerosol analyser; fog microstructure; cloud microstructure; fog droplet; cloud droplet; cloud; fysisk instrumentering; fog; Metrologi; physical instrumentation; Metrology; Kärnfysik; Nuclear physics; Fysik; Fysicumarkivet A:2001:Frank;

    Abstract : In this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. READ MORE

  4. 2. Hygroscopic Growth of Atmospheric Aerosol Particles and Its Relation to Nucleation Scavenging in Clouds

    Author : Birgitta Svenningsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosol formation; atmospheric aerosols; hygroscopic growth; nucleation scavenging; cloud; water activity; external mixing; tandem differential mobility analyser; Kärnfysik; cloud condensation nuclei spectra; Nuclear physics; TDMA; Fysicumarkivet A:1997:Svenningsson; inorganic salts;

    Abstract : Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. READ MORE

  5. 3. Hygroscopic Properties of Atmospheric Aerosol Particles in Various Environments

    Author : Jingchuan Zhou; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tandem differential mobility analyser TDMA ; internal and external mixture; closure study; GDF95; AOE-96; Fysik; Physics; Kärnfysik; Nuclear physics; ACE-2; CLAIRE98; differential mobility particle sizer DMPS ; atmospheric aerosol particles; hygroscopic growth; Fysicumarkivet A:2001:Zhou;

    Abstract : Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the differential mobility particle sizer (DMPS). READ MORE

  6. 4. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass

    Author : Jenny Rissler; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cloud condensation nuclei; H-TDMA; CCN; hygroscopic growth; Teknik; internal and external mixture; CLAIRE; SMOCC; Physics; Fysik; Environmental chemistry; Technological sciences; Miljökemi; tandem differential mobility analyzer; slash and burn; Amazon; Biomass burning; combustion; Fysicumarkivet A:2005:Rissler;

    Abstract : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.

  7. 5. Searches for Higgs bosons with hadronically decaying τ-leptons : Using Grid and Cloud computing techniques

    Author : Henrik Öhman; Arnaud Ferrari; Paula Eerola; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; Higgs; Charged Higgs; Tau lepton; 2HDM; MSSM; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis describes a measurement of the Standard Model Higgs boson coupling to fermions in decays to two τ-leptons, a search for charged Higgs bosons in decays to a τ-lepton and a neutrino, as well as the reconstruction, identification and triggering of hadronically decaying τ-leptons. The data considered are collected by the ATLAS experiment at the Large Hadron Collider. READ MORE
