  1. 16. Minimally Invasive Catheter-Based Technologies

    Författare :Mikael Sandell; Göran Stemme; Staffan Holmin; Niclas Roxhed; Wouter van der Wijngaart; Stefan Jonsson; Duncan Maitland; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknologi; Medical Technology;

    Sammanfattning : A simple incision procedure in a blood vessel makes the entire vascular system accessible. Through contrast injection and X-ray visualization, the vascular tree can be mapped and navigated through manual manipulation of thin tubes and wires. LÄS MER

  3. 17. Assessment of stormwater and snowmelt quality based on water management priorities and the consequent water quality parameters

    Författare :Helen Galfi; Maria Viklander; Jiri Marsalek; Helene Österlund; Jon M. Hathaway; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; indicator bacteria; water quality assessment; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Stormwater and snowmelt pollution contributes to degradation of quality of the receiving waters. For assessing such impacts, it is effective to focus on specific causes of degradation, as done in this study of the quality of stormwater and snowmelt discharges into the receiving waters serving for supply of raw drinking water and water-based recreation.

  4. 18. Airborne Isocyanates, Aminoisocyanates and Amines

    Författare :Daniel Karlsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental health; Miljökemi; Environmental chemistry; amines; aminoisocyanates; isocyanates; polyurethane; exposure; occupational; thermal degradation; chemiluminescence; mass spectrometry; Liquid chromatography; gas chromatography; Miljömedicin; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. LÄS MER

  5. 19. Navigating the Critical Nexus. Bridging Simulation, Measuring, and Acid-Base diagnosis in ICU and Dialysis

    Författare :Innas Forsal; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Algorithm; Dialysis; Acid-base; Software; Diagnosis; Decision support tool;

    Sammanfattning : Intensivvårdsavdelningen (IVA) tar hand om de mest kritiskt sjuka patienterna, ofta med multiorgansvikt. Denna patientgrupp kräver kontinuerlig övervakning av vitala funktioner som blodtryck, EKG och syremättnad. Varje patient på IVA kräver dessutom upprepad provtagning, ibland så ofta som var 15:e min.

  7. 20. Aerosol Measurements as Applied for Exposure Characterization

    Författare :Andreas Dahl; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Sammanfattning : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. LÄS MER
