    Sammanfattning : Measurements of the cleanliness level have been performed in operating rooms classified as tissue and cells establishments for bone tissue to compare the results with the requirements given in the Tissue and Cells Directives of the European Union (EUTCD). The results show that the requirements are not always fulfilled. LÄS MER

  4. 4. Image Analysis for Diagnostics of Insulators with Biological Contamination

    Författare :Andreas Dernfalk; Chalmers University of Technology; []
    Nyckelord :climate chamber; fungi; composite insulators; biological contamination; digital image analysis; Outdoor insulation; algae; leakage current measurements;

    Sammanfattning : Composite insulators have a number of advantages compared to conventional insulators. However, the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the performance of the materials. LÄS MER

  5. 5. Fat contamination of pericardial suction blood in cardiac surgery : clinical and experimental studies in perspectives of transfusion logistics

    Författare :Micael Appelblad; Gunnar Engström; Krister Lindmark; Anders Jeppsson; Umeå universitet; []
    Nyckelord :Surgery; blood transfusion; cardiopulmonary bypass; pericardial suction blood; fat contamination; lipid microemboli; density separation; surface adsorption; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Introduction: During cardiac surgery aided by cardiopulmonary bypass (CPB) the autotransfusion of pericardial suction blood (PSB) is regarded mandatory to limit allogeneic blood exposure. PSB is however proposed as a source of lipid microemboli and to contribute to brain damage. LÄS MER
