  1. 11. Cycle paths’ degradation processes and surface condition assessment

    Författare :Martin Larsson; Sigurdur Erlingsson; Anna Niska; Inge Hoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction design; cycle paths; degradation; distress modes; maintenance; municipalities; survey; cycling comfort; road surface measurements; surface evenness; surface texture; Building Materials; Byggnadsmaterial;

    Sammanfattning : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. LÄS MER

  4. 13. Oxidative Degradation of Polyethylene - A Cause of Off-flavour

    Författare :Thorbjörn Andersson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; off-flavour; degradation; polyethylene;

    Sammanfattning : Polyethylene is the most frequently used polymer material in food packaging today. The polymer is often processed by film extrusion and extrusion coating between 250°C and 325°C. LÄS MER

  5. 14. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

    Författare :Benoit Guieysse; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

    Sammanfattning : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. LÄS MER

  7. 15. The role of glial cells in alpha-synuclein pathology : Focus on degradation, cell-to-cell propagation and inflammation

    Författare :Jinar Rostami; Anna Erlandsson; Martin Ingelsson; Joakim Bergström; Michael Heneka; Uppsala universitet; []
    Nyckelord :Parkinson’s disease; alpha-synuclein; amyloid-beta; astrocytes; microglia; tunneling nanotubes; antigen presentation; T cells; glial crosstalk; degradation; KYP-2407; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Growing evidence emphasizes the role of astrocytes and microglia in Parkinson’s disease (PD) and Alzheimer’s disease (AD). Yet, little is known about their impact on specific disease processes and if their involvement is beneficial or detrimental. LÄS MER
