  1. 1. Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic

    University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Author : Patrik Winiger; Örjan Gustafsson; Meinrat O. Andreae; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Radiocarbon; Air Pollution; Arctic Amplification; Climate Change; Arctic Haze; Atmospheric Transport Modeling; Emission Inventory; Carbon Isotopes; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation interactions (ari) and aerosol cloud interactions (aci). READ MORE

  2. 2. Inflammation and wound healing following photorefractive keratectomy

    University dissertation from Stockholm : Karolinska Institutet, -

    Author : Santiago Tomás Barberán; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Photorefractive keratectomy; excimer laser; inflammation; flare; prostaglandins; diclofenac; dexamethasone; pain; epithelial healing; corneal topography; growth factors; metalloproteinases; collagen; haze; haze distribution; Scheimpflug system; Laser Flare Meter; regression; reoperation; wound healing;

    Abstract : This study comprises different aspects on the inflammatory and wound healing responses of the eye after Photorefractive Keratectotmy (PRK). The purpose was to provide basic information about the inflammatory reaction and the wound healing after surgery. PRK is considered a good technique for surgical correction of and moderate myopia.

  3. 3. Refractive surgery with the ArF excimer laser (Photorefractive keratectomy) : Surgical technique, wound healing and refractive results

    University dissertation from Stockholm : Karolinska Institutet, false

    Author : Heléne Hamberg-Nyström; Karolinska Institutet.; Karolinska Institutet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Photorefractive keratectomy; excimer laser; comparison; centration; contrast sensitivity; night vision; endothelial cell; epithelial thickness; multipassmultizone; multizone; haze; saccades; hyaluronan; myopic regression; reoperation; wound healing.;

    Abstract : Excimer lasers have been adapted to treat refractive errors in the human eye since1987. By remodeling the corneal surface, myopia and astigmatism can be corrected.The investigations herein were performed during a time period when the surgical techniquedevelopment was extensive.

  4. 4. Water, hyaluronan and surface shape in corneal wound healing after excimer surgery : experimental studies

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Sciences

    Author : Beat A. Weber; Karolinska Institutet.; Karolinska Institutet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photorefractive keratectomy; excimer laser; rabbit; cornea; wound healing; microradiography; hyaluronan; planimetry; leukocyte protein marker; haze; regression; surface irregularities; subepithelial deposits; remodeling; epithelial hyperplasia; corticosteroids;

    Abstract : Excimer laser photorefractive keratectomy (PRK) has evolved to a widely performed procedure. The excimer laser corrects refractive ametropias by removing a calculated amount of anterior corneal stroma with great precision and with minimal damage to the adjacent tissues. The correction of myopia up to -5. READ MORE

  5. 5. Light propagation in an anisotropically scattering medium

    University dissertation from KTH Royal Institute of Technology

    Author : Elena Vasileva; Sergei Popov; Miguel A. Alonso; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropic light scattering; scattering material characterization; polarization dependent scattering; diffusive media; hierarchical structure; biocomposites; wood modification; transparent wood; microfibrils angle; organic materials; polymer active devices; dye lasers; coherence; polarization; degree of polarization.; Physics; Fysik;

    Abstract : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. READ MORE
