  1. 11. Characterization of soot in air and rain over southern Asia

    Författare :Erik J. Engström; Caroline Leck; Henning Rodhe; Paolo Laj; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soot; black carbon; atmospheric concentration; light absorption; wet deposition; scavenging; wash-out ratio; South-Asia.; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap;

    Sammanfattning : Filter-based optical measurements of light absorbing particulate matter at awavelength of about 550 nm, here referred to as soot, in air and rainwaterhave been performed during the period from 1st June 2005 to 31th May 2009at Godavari in Nepal, Sinhagad in India and Hanimaadhoo in The Maldives.A method for determination of water-insoluble light absorbing matter inrainwater has been developed.

  3. 12. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

    Författare :Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

    Sammanfattning : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. LÄS MER

  4. 13. Hyperglycemia, nutrition and health outcomes in preterm infants

    Författare :Itay Zamir; Magnus Domellöf; Elisabeth Stoltz Sjöström; Kathryn Beardsall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neonatal hyperglycemia; preterm infants; early programming; insulin; blood pressure; neurodevelopment; MABC-2; EXPRESS; LIGHT; continuous glucose monitoring; parenteral nutrition; postnatal growth; pediatrik; Pediatrics;

    Sammanfattning : BackgroundSurvival among very low birth weight (VLBW) and extremely preterm (EPT) infants has increased markedly during the last decades. Neonatal hyperglycemia is common in these infants and is known to be associated with adverse outcomes. LÄS MER

  5. 14. Measuring and modelling light scattering in paper

    Författare :Niklas Johansson; Per Edström; Mattias Andersson; Magnus Neuman; Jon Yngve Hardeberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; goniophotometry; anisotropy; angle resolved light scattering; reflectance measurements; turbid media;

    Sammanfattning : Avhandlingen behandlar de teoretiska och praktiska aspekterna av att använda spektrala vinkelupplösta reflektansmätningar för optisk karakterisering av fiberbaserade material såsom papper och kartong. En spektral goniofotometer används för att mäta det reflekterade ljusets vinkelfördelning. LÄS MER

  7. 15. Implications of light scattering and secondary structure in protein concentration determination

    Författare :Nils Carlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When using proteins in applications the amount of protein is a fundamental property. For enzyme immobilization there is a need to measure the protein concentration at a solid support. The system studied in this work is mesoporous particles. LÄS MER
