  4. 13. Att vårdas vaken med respirator : patienters och närståendes upplevelser från en intensivvårdsavdelning

    Författare :Veronika Karlsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; mechanical ventilation; conscious; patient communication; relatives; experiences; standing by; hermeneutics; phenomenological-hermeneutics; content analysis; Vårdvetenskap; Nursing science; intensive care; mechanical ventilation; conscious; patient; communication; relatives; experiences; standing by; hermeneutics; phenomenological-hermeneutics; content analysis;

    Sammanfattning : In recent years, light or no sedation has become a common approach in patients who require mechanical ventilation (MV) when cared for in an intensive care unit (ICU). This new approach has resulted in medical advantages as well as a shorter time on MV and in the ICU. LÄS MER

  5. 14. Application of high-frequency mechanical impact treatment for fatigue strength improvement of new and existing bridges

    Författare :Hassan al-Karawi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; Bridges; Fatigue; Crackdetection; HFMI; Finiteelement; Steel; Lifeextension; Post-weldtreatment; Variableampli- tude;

    Sammanfattning : This thesis investigates the application of High-Frequency Mechanical Impact (HFMI) treatment for fatigue strength improvement of weldments in existing and new bridges. In the former case, the welds have already been subjected to fatigue loading and accumulated damage before treatment. LÄS MER

  7. 15. Mechanical Properties of Arteries : An In Vivo Parameter Identification Method

    Författare :Jan-Lucas Gade; Jonas Stålhand; Carl-Johan Thore; Stéphane Avril; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this dissertation, a method is proposed that identifies the mechanical properties of arteries in vivo. The mechanical properties of an artery are linked to the development of cardiovascular diseases. LÄS MER
