  1. 1. Assessment of physical activity and energy expenditure in adolescents

    Författare :Ulf Ekelund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Accelerometry; Activity diary; Doubly labelled water; Heart rate monitoring; FLEX HR; Oxygen uptake; Physical activity level; Total energy expenditure; ;

    Sammanfattning : Physical activity (PA) is a complex, multidimensional human behaviour that includes all bodily movement from fidgeting to participation in marathon running. The detailed relationship (i.e. dose - response) between the type and degree of PA and its effects on various aspects of health remains to be elucidated, not least in young people. LÄS MER

  4. 3. Long-term performance of poly(vinyl chloride) cables : mechanical and electrical performances and the effect of plasticizer migration

    Författare :Maria Ekelund; Ulf W. Gedde; Minna Hakkarainen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poly vinyl chloride cables; ageing; mechanical properties; plasticizer migration; Polymer chemistry; Polymerkemi;

    Sammanfattning : Cables insulated with plasticized poly(vinyl chloride) were aged at temperatures between 80 and 180 °C in air and their conditions were assessed by indenter modulus measurements, tensile testing, infrared (IR) spectroscopy, differential scanning calorimetry (DSC) and liquid chromatography (HPLC). Electrical testing of oven-aged cable samples was performed in order to relate the electrical functionality during a high-energy line break accident to the mechanical properties and to establish a lifetime criterion.

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

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

    Sammanfattning : 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. LÄS MER
