  2. 1. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    Author : Mikael Hamskog; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Abstract : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. READ MORE

  4. 2. Chromatography and extraction techniques for new evaluation methods of polyolefins long-term performance

    Author : Lina Burman; Ann-Christine Albertsson; Marek Kowalczuk; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; polymer; chromatographic fingerprinting; gas-chromatography – mass spectrometry; GC-MS; degradable polyethylene; prooxidant systems; chemiluminescence; oxidation; degradation mechanisms; accelerated ageing; antioxidants; transformation products; microwave assisted extraction; MAE; solid-phase microextraction; SPME; volatiles; solid phase extraction; SPE; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : Chromatography and extraction techniques, and also chemiluminescence have been utilized to develop new rapid and informative tools in the evaluation of long-term properties and environmental effects of polymeric materials. Methods were developed for classification of materials and for early and rapid degradation detection. READ MORE

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

    Author : Derek Filbey; Lennart Rydberg; Linköpings universitet; []
    Keywords : 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

  6. 4. Luminol chemiluminescence and some analytical applications in biochemistry and microbiology

    Author : Lena Ewetz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The chemiluminescent luminol reaction was studied in the presence of hematin compounds and perborate. It was found that the maximum rate of light emission of chemiluminescence was proportional to initial concentrations of all participating reactants and that perborate promoted destruction of the hematin compounds concomitant with the decline of the rate of chemiluminescence.

  7. 5. Hyperbaric oxygen. Effects on ischemia-reperfusion

    Author : Johan Tjärnström; Göteborgs universitet; []
    Keywords : fibrinolysis; f-MLP; human; hyperbaric oxygen; neutrophils; normobaric; PAI-1; PMA; rat; t-PA; trauma; uPA;

    Abstract : Treatment with hyperbaric oxygen (HBO2) is controversial when treating other disorders than decompression sickness. However, HBO2 is a treatment modality that has gained recognition in certain ischemia-reperfusion situations. READ MORE
