  1. 1. Treatment of Right Ventricular Failure through Partial Volume Exclusion : An Experimental Study

    Författare :Per Vikholm; Laila Hellgren; Lund Lars; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Right Heart Failure; Left Ventricular Assist Device; Glenn shunt; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Implantation of a left ventricular assist device (LVAD) is a potential treatment in terminal heart failure. Right ventricular (RV) failure is a severe complication in these patients and sometimes requires additional placement of a right ventricular assist device (RVAD). LÄS MER

    Sammanfattning : Melt Spun Piezoelectric Textile Fibres - an Experimental Study ANJA LUND Department of Materials and Manufacturing Technology Chalmers University of Technology ABSTRACT The manufacturing and characterisation of piezoelectric textile fibres are described in this thesis. A piezoelectric material is one that generates an electric voltage when deformed, a property which exists in a number of materials. LÄS MER

  3. 3. Mineral fibers, cigarette smoke, and oxidative DNA damage : An experimental study

    Författare :Per Leandersson; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This study concerns the ability of mineral fibers and cigarette smoke to generate reactive oxygen metabolites and to cause damage to DNA. The generation of hydroxyl radicals (OH") was demonstrated by using the DNA base, deoxyguanosine (dG) as a trapping agent for OH" and determining its hydroxylation to 8-hydroxydeoxyguanosine (80HdG), and oxidative DNA damage was assessed as formation of 80HdG in isolated DNA or in DNA of human lung cells in culture.

  4. 4. Nitric oxide and extravasation in endotoxaemia : an experimental study

    Författare :Kerstin Metcalf; Mikael Bodelsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Background: Despite advances in intensive care the mortality of patients in septic shock is still high. In early stages the condition is characterised by circulatory failure that is a consequence of myocardial depression, vasodilatation with decreased sensitivity to catecholamine stimulation and increased loss of protein and fluid from the circulation.

  5. 5. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

    Författare :Claes Blomqvist; Mats Sandberg; Per Heiselberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

    Sammanfattning : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.
