  1. 11. Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Anneli Ågren; Umeå universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DOC; temporal variation; spatial variation; seasonal variation; forested catchment; wetland catchment; catchment characteristics; DOC characteristics; absorbance-ratio; bioavailability.; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Abstract : The seasonal variation and landscape regulation of dissolved organic carbon (DOC) concentrations in streams have been studied in two watersheds in the boreal zone. The seasonal variation was found to be highly correlated to variations in runoff. An increase in runoff was always accompanied with an increase in DOC concentration. READ MORE

  2. 12. Very preterm birth : Etiological aspects and short and long term outcomes

    University dissertation from Stockholm : Karolinska Institutet, Department of Medical Epidemiology and Biostatistics

    Author : Stefan Johansson; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Very preterm birth, occurring before 32 completed weeks of gestation, is an often unexplained pregnancy complication affecting approximately 1 to 2 percent of all births. This thesis includes four studies regarding the etiology, and short and long term outcomes of very preterm birth, using Swedish population-based data. READ MORE

  3. 13. Synthesis of functional degradable polymers by radical ring-opening polymerization

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jenny Undin; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tissue engineering; ring-opening polymerization; 2; 2´-azoisobutyronitrile; cyclic ketene acetals; 2-methylene- 1; 3; 6-trioxocane; 2-methylene- 1; 3-dioxepane; vinyl acetate; coopolymerization;

    Abstract : The increased demand for understanding cell-material interactions and subsequently create personalized implants for tissue engineering has resulted in an increased interest in developing new monomers with functional groups. The focus of the work presented in this thesis has been on the synthesis of functional monomers and the polymerization of these into functional amorphous aliphatic polyesters. READ MORE
