  1. 21. Imaging chemiluminescence applied to oxidation of rubber materials and polyamide

    University dissertation from Institutionen för polymerteknologi

    Author : Gustav Ahlblad; [1998]
    Keywords : ;

    Abstract : In this thesis the heterogeneous nature of thermal oxidationof polymer materials have been investigated by imagingchemiluminescence (KL). The issues of oxidation depth profilesand physical spreading of oxidation in rubbers materials andpolyamide have been addressed. READ MORE

  2. 22. Alloimmunization during pregnancy with special emphasis on anti-D : Laboratory and clinical management

    University dissertation from Linköping : Linköpings universitet

    Author : Derek Filbey; Lennart Rydberg; [1995]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alloimmunization in pregnancy; Anti-D; Haemolytic disease of the newborn HDN ; IAT-titration; AA-quantitation; Chemiluminescence test; Category D; HLA class II antibodies; MEDICINE; MEDICIN;

    Abstract : The laboratory and clinical management of alloimmunized in pregnancy has been investigated according to a protocol currently in use in Örebro region. A 12 year epidemiological study showed the prevalence of alloimmunization to be 0.57% in this Swedish populationwith a 0. READ MORE

  3. 23. Long-term properties of polyethylene films efficiency of a natural antioxidant

    University dissertation from Stockholm : KTH

    Author : Clara Strandberg; Ann-Christine Albertsson; Jukka Seppälä; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. READ MORE

  4. 24. Spark Assisted Compression Ignition, SACI

    University dissertation from Stockholm : KTH

    Author : Håkan Persson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame propagation; PLIF; LDV; chemiluminescence imaging; residuals; negative valve overlap; low temperature combustion; SACI; spark assistance; HCCI; turbulence; charge stratification; cycle to cycle;

    Abstract : The strong focus on decreasing carbon dioxide emissions due to limited natural resources of fossil fuel as well as alarming climate changes drives the research and development of our prime mover, the combustion engine, faster then ever. The minimum requirement is a power source with increased efficiency while emitting ultra low levels of hazardous local and regional emissions. READ MORE

  5. 25. Studies on Diesel sprays under non-reacting and reacting conditions

    University dissertation from Gothenburg : Chalmers tekniska högskola
