  3. 2. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams : Model Assessments Based on Tracer Tests

    Författare :Karin Jonsson; Anders Wörman; Bernhard H. Schmid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; conservative; hyporheic exchange; model; reactive; retention; solute; sorption kinetics; stream transport; temporal moments; tracer experiment; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

  4. 3. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites

    Författare :Roland H. Krämer; Ulf W. Gedde; Mats Jonsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; methacrylic acid; ethylene; calcium carbonate; ionomer; nanoparticles; intumescence; halogen-free; flame retardant; melt dripping; Polymer chemistry; Polymerkemi;

    Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER

    Sammanfattning : The turn of the 20th century was a formative period of industrialisation and class formation, and a key period in the development of European systems of vocational education and training. At that time, apprenticeship training was frequently debated in Sweden, just as it was in many other parts of Europe. LÄS MER
