  1. 11. Quality of snow deposited in urban areas : Storage, load assessment and release of selected pollutants with snowmelt

    Författare :Arya Vijayan; Maria Viklander; Helene Österlund; Jiri Marsalek; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Snow deposited in urban areas is exposed to pollutants originating from traffic, wet and dry atmospheric deposition, de-icing chemicals and traction materials. The conventional pollutants found in urban snow include solids (TSS), metals (Zn, Cu, Cd, Pb, etc.), Polycyclic Aromatic Hydrocarbons (PAHs), and chlorides. LÄS MER

  3. 12. Weight scaling : methods to determine the quantity of pulpwood

    Författare :Mikael Hultnäs; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Scaling pulpwood according to its weight for payment purposes is done in many places around the world. In North America, pulpwood is commonly scaled according to its green weight, while in Central Europe the wood is commonly scaled according to its dry weight. In Sweden pulpwood is measured according to its volume. LÄS MER

  4. 13. Removal of Natural Organic Matter to reduce the presence of Trihalomethanes in drinking water

    Författare :Indiana Garcia; Luis Moreno; Bhekie B. Mamba; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi;

    Sammanfattning : In countries located in tropical zones, a critical task in drinking water plants is the removal of the natural organic matter (NOM), particularly during the rainy season when a lot of organic matter is transported by run-off into the water bodies. It provokes overloaded in the plants and they have often needed to be shut down. LÄS MER

  5. 14. From Lab to Chip – and back : Polymer microfluidic systems for sample handling in point-of-care diagnostics

    Författare :Jonas Hansson; Wouter van der Wijngaart; Hywel Morgan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis contributes to the development of Lab-on-a-Chip systems that enables reliable, rapid medical diagnostics at the point-of-care. These contributions are focused on microfluidic Lab-on-a-Chip systems for sepsis diagnosis, autonomous sample-to-answer tests, and dried blood spot sampling. LÄS MER

  7. 15. Wild vegetables and micronutrient nutrition : Studies on the significance of wild vegetables in women's diets in Vietnam
