  1. 1. Staphylococci in cardio-thoracic surgery : Epidemiological and clinical studies

    Författare :Ann Tammelin-Brandemark; Uppsala universitet; []
    Nyckelord :Medical sciences; Coagulase negative staphylococci; Staphylococcus aureus; MRSE; carriage; dispersal; air counts; scrub suit; PFGE; mediastinitis; sternal dehiscence; diagnosis.; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Bacteriology; klinisk bakteriologi;

    Sammanfattning : Mediastinitis complicating cardio-thoracic surgery causes suffering to the patient and huge costs to the society. It is often caused by methicillin resistant S. epidermidis (MRSE) and S. aureus. LÄS MER

  3. 2. Health effects of air pollution : innovative approaches for spatio-temporal evaluations

    Författare :Massimo Stafoggia; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Air pollution is one of the major risk factors to human health, causing both short- and long-term effects and the global burden on mortality is estimated in more than 4 million deaths every year. Most of the evidence on the short-term effects is based on studies conducted in major cities, because data or estimates of air pollutants exposures in non-urban settings have been historically lacking.

  4. 3. Cytokines and their soluble receptors in nasal fluids from school children with allergic rhinitis

    Författare :Mikael Benson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allergic rhinitis; school children; cytokines; soluble cytokine receptors; nasal fluids;

    Sammanfattning : Allergic inflammation is associated with a shift in the balance between cytokines produced by two T helper subsets (Th1 and Th2) towards a preponderance of Th2 cells. Interleukin (IL)-4 is produced by Th2 cells and interferon-g (IFN-g) by Th1 cells. The ratio IL-4/IFN-g is often used as a marker of the balance between the cytokines. LÄS MER

  5. 4. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs

    Författare :Göran Frank; Kärnfysik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. New Approaches to Investigate and Prevent Oxidation of Polypropylene

    Författare :Petter Eriksson; KTH; []
    Nyckelord :oxidation; polypropylene; oxidative spreading; antioxidants; hyperbranched antioxidants;

    Sammanfattning : When employing chemiluminescence to evaluate stabiliserperformance in a polymer, the induction time or the time toreach maximum chemiluminescence intensity is often used. Insuch an experiment the longest part of the experiment isnormally the time before the oxidation starts. LÄS MER
