  1. 1. Biomarkers in Multiple Sclerosis - Monitoring disease activity and treatment afficacy

    Författare :Lenka Nováková Nyrén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomarkers; multiple sclerosis; neurodegeneration; inflammation; treatment;

    Sammanfattning : The pathophysiology of multiple sclerosis (MS) is complex with the presence of inflammation and neurodegeneration in all stages of the disease. The disease course, treatment response and outcome are highly variable in MS. LÄS MER

  4. 3. Recovery of copper and zinc in ashes from municipal solid waste combustion

    Författare :Jinfeng Tang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyanex 923; MSWI waste; LIX860-I; acidic leaching; waste treatment.; copper; solvent extraction; zinc;

    Sammanfattning : The amount of municipal solid waste incineration (MSWI) fly ash has increased in many parts of the world in recent years. Ashes from municipal solid waste incineration (MSWI) may be a cumbersome waste to handle since containing significant amounts of leachable hazardous metal species and must be landfilled in special sites at high costs.

  5. 4. Hydrometallurgical Treatment of Neodymium Magnet Waste

    Författare :Marino Gergoric; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; recycling; rare-earth elements; leaching; Keywords: neodymium magnets; solvent extraction;

    Sammanfattning : Recent decades have seen a considerable increase in the usage of rare-earth elements (REEs) in modern technologies and green energy sources. Recycling of REEs out of end-of-life products and E-scrap has become an alternative to mining them out of primary ores due to their supply risk in some countries and the development towards circular economies.

  7. 5. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

    Författare :Mattias Nilsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

    Sammanfattning : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. LÄS MER
