  1. 1. Regenerative medicine of the airway cartilage : A morphological and immunohistochemical study with focus on cricoid cartilage defects treated with BMP-2

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

    Author : Ion Tcacencu; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Larynx; growth factor; wound healing; perichondrium; progenitor cells; osteogenesis; growth plate.;

    Abstract : Background. Cartilage provides flexible support for upper airway. Induction of cartilage healing is required for the success of many surgical interventions in the head and neck that are used as treatments for several diseases, such as subglottic stenosis and tumors of the larynx and thyroid.

  2. 2. Some aspects on TCF-bleachability of softwood alkaline pulps

    University dissertation from Stockholm : KTH

    Author : Karin Sjöström; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bleachability; chlorine-free bleaching; softwoods; kraft pulps; alkaline sulfite pulps; oxygen; hydrogen peroxide; ozone; hydrogen sulfide ion; hydroxide ion; temperature; sodium ion.; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : The bleachability of softwood oxygen delignified pulps has been studied, i.e. the ease (requirement of bleaching chemicals) with which the pulps can be brightened to a target brightness in totally chlorine free (TCF) bleaching stages, including hydrogen peroxide, ozone and chelating agent stages.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon nanoparticle; Photoluminescence; Ion beam synthesis; Ion beam analysis; Fysik; Physics;

    Abstract : Silicon nanoparticles (SiNPs) have been shown to display luminescence in the visible range with a peak wavelength depending on the nanoparticle size. This finding is of potential interest for integration of optoelectronic devices in semiconductor technology. READ MORE

  4. 4. Low-Energy Ion Escape from the Terrestrial Polar Regions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Engwall; Anders I. Eriksson; Mats André; Thomas Moore; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space physics; ion outflow; polar wind; auroral upflows; atmospheric escape; magnetotail lobes; spacecraft wake; electric field measurements; NATURAL SCIENCES Physics Geocosmophysics and plasma physics; NATURVETENSKAP Fysik Geokosmofysik och plasmafysik; Space and Plasma Physics; rymd- och plasmafysik;

    Abstract : The contemporary terrestrial atmosphere loses matter at a rate of around 100,000 tons per year. A major fraction of the net mass loss is constituted by ions, mainly H+ and O+, which escape from the Earth’s ionosphere in the polar regions. READ MORE
