  3. 2. The effect of protein intake and physical exercise on energy turnover and substrate utilisation at energy balance in man

    Författare :Anders H. Forslund; Uppsala universitet; []
    Nyckelord :Medical sciences; Body composition; carbohydrate; energy turnover; fat; protein; stable isotopes; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Nutrition; näringslära;

    Sammanfattning : The principal goal of the thesis has been to evaluate the effect of protein intake and physical exercise on energy turnover and substrate utilisation. Body composition assessment is of importance as an indicator of the energy balance. Therefore, in the first study the aim was to develop new models to estimate body composition more accurately.

  5. 4. New Tools for Analysis of Wood and Pulp Components - Application of MALDI-TOF Mass Spectroscopy and Capillary Zone Electrophoresis

    Författare :Anna Jacobs; KTH; []
    Nyckelord :Capillary zone electrophoresis; carbohydrate composition; degree of acetylation; degree of polymerization; enzymatic hydrolysis; hardwood; hemicellulose; hexenuronic acid; lignin; MALDI-TOF mass spectroscopy; molar mass; molar mass distribution; olig;

    Sammanfattning : In the present thesis, capillary zone electrophoresis (CZE),matrix-assisted laser desorption/ionization time-of-flight massspectroscopy (MALDI-MS) and size-exclusion chromatography incombination with off-line MALDI-MS (SEC/MALDI-MS) have beenapplied successfully to the analysis of wood and pulpcomponents.The carbohydrate compositions of pulp and holocellulosesamples, as well as of isolated hemicellulose preparations,were determined employing enzymatic hydrolysis and subsequentanalysis of the saccharides released by CZE.

  7. 5. Towards a pure kraft lignin

    Författare :Rufus Ziesig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; black liquor; lignin; impurities; purification; carbohydrate; inorganics; precipitation;

    Sammanfattning : The most widely used production method for paper pulp in the world is kraft pulping. In chemical pulping the polymer, lignin, which binds the wood fibres together, is partly depolymerized. This allows the wood fibres to be separated from each other. LÄS MER
