  2. 21. Long-term Performance of PVC and CSPE Cables used in Nuclear Power Plants : the Effect of Degradation and Plasticizer migration

    Author : Maria Ekelund; Ulf Gedde; Thomas Hjertberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCV; CSPE; cables; ageing; mechanical properties; plasticizer migratio; LIRA; life time prediction; Chemistry; Kemi;

    Abstract : Enormous amounts of low voltage cables installed in a Swedish nuclear power plant are reaching their expected lifetimes. Since the cables are crucial to operational safety, it is of great importance that the actual condition of the installed cables is determined. READ MORE

  4. 22. Plasticized PVC Nanocomposites - The Effect of Montmorillonite Treatment and Processing Conditions on Material Properties

    Author : Henrik Petersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melt processing; Montmorillonite; mechanical properties; scanning electron microscopy; X-ray diffraction; poly vinyl chloride ; organic modification; barrier properties;

    Abstract : ABSTRACTPolyvinyl chloride (PVC) is one of the world’s most widely produced polymers. Its products are used in a wide range of areas such as building and construction, packaging, automotive, electrical/electronic and healthcare. PVC can easily be tailored to adapt material properties to specific applications. READ MORE

  5. 23. Material development of a textile bioreactor : All-polyamide composite for the construction of bioreactors

    Author : Mostafa Jabbari; Mikael Hedenqvist; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; textile bioreactor; biofuel; coated fabric; all-polyamide composite; polyvinyl chloride PVC ; solvent replacement; Hansen solubility parameters HSPs ; Resource Recovery; Resursåtervinning;

    Abstract : Bioreactors are manufactured from stainless/carbon steel, concrete, glass, etc., which are costly and time-consuming to install. Recently, several research studies have been initiated to find cost-efficient materials for constructing bioreactors, one of which is coated textiles. READ MORE

  6. 24. Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries

    Author : Yajing Wu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Swirling flow; swirler; vortex breakdown; precessing vortex core PVC ; large eddy simulation LES .;

    Abstract : This thesis deals with the physics of turbulent swirling flows. Large eddy simulation (LES) method is used to investigate the vortex breakdown process, the precessing vortex core (PVC), and the effect of swirl number and flow field configuration on swirling flows. The study is based on an open source CFD code, \textit{OpenFoam}. READ MORE

  7. 25. Peripheral venous catheters : quality of care assessment

    Author : Margary Ahlqvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : About half of the patients admitted to hospitals receive intravenous therapy through peripheral venous catheters (PVCs). Unfortunately, the use of PVCs is associated with the risk of complications that may lead to increased morbidity and prolonged hospitalisation. READ MORE
