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

    Författare :Mikael Hamskog; Centrum för analys och syntes; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 13. Hydrogeophysics of Tropical Africa : Recent advances and perspectives

    Författare :Elónio Muiuane; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : In the present work an attempt is made to put into perspective the hydrogeophysical investigations for rural water supply carried out over the last two decades in tropical Africa, paying special attention to groundwater targets in the weathered rocks in and above the crystalline basement. The applicability of geophysical techniques in groundwater investigations in tropical Africa, particularly the DC resistivity and electromagnetic techniques is discussed in the light of recent developments in instrumentation, data collection and interpretation procedures.

  5. 15. Working Conditions, Income Differences, and Sense of Coherence in Relation to Ill Health

    Författare :Susanna Toivanen; Örjan Hemström; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; working conditions; income; sense of coherence; Sociology; Sociologi;

    Sammanfattning : The licentiate thesis explored the relationship between working conditions and wage income, and the relationship between working conditions and sense of coherence in relation to ill health, focusing on cardiovascular disease, musculoskeletal pain, and psychological distress among the working population in Sweden. The studies were based on cross-sectional and longitudinal survey data (ULF and LNU), and on the Swedish census (FoB90) linked to the national cause of death registry. LÄS MER
