  2. 1. Bioprocessing, Structure and Material Properties of Arabinoxylans

    Author : Anders Höije; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture content; biorefinery; Arabinoxylan; mechanical properties; chemical structure; isolation; film formation; oxygen permeability; enzymatic treatment;

    Abstract : This work has focused on using agriculture residues as raw material for new polymeric materials. Arabinoxylans have been isolated from barley husks and endosperm fiber using alkali extraction, and the chemical composition and detailed structure have been determined. READ MORE

  4. 2. Isolation, Characterization and Material Properties of Arabinoxylan from Barley

    Author : Anders Höije; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical structure; moisture content; film formation; Arabinoxylan; isolation; mechanical properties; oxygen permeability;

    Abstract : The growing amount of household waste and the limited supply of fossil fuel on earth make it important to find renewable resources for the production of biodegradable polymers for a variety of applications, particularly as packaging and other disposable products. Hemicelluloses are important components in all plants and the second most abundant plant biopolymers on earth. READ MORE

  5. 3. Cox-2 inhibitors of natural origin : Dereplication, isolation, and structure elucidation

    Author : Wimal Pathmasiri; Uppsala universitet; []
    Keywords : ;

    Abstract : .... READ MORE

  6. 4. Genetic structure and dispersal in plant populations

    Author : Johan Fogelqvist; Martin Lascoux; Sophie Gerber; Beng-Olle Bengtsson; Uppsala universitet; []
    Keywords : population genetics; dispersal; structure; plant; gene flow;

    Abstract : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.

  7. 5. Population Fragmentation and Genetic Variation in Grouse

    Author : Jobs Karl Larsson; Jacob Höglund; Stuart B. Piertney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Bonasa sewerzowi; bottleneck; genetic drift; genetic variation; inbreeding; isolation; microsatellites; population structure; Tetrao tetrix; Biologi; Biology; Biologi;

    Abstract : In this thesis the genetic variation of two grouse species, the Chinese grouse (Bonasa sewersowi) and the Black grouse (Tetrao tetrix) was examined with neutral genetic markers: microsatellites. Habitat fragmentation and isolation leads to structuring among and loss of genetic variation within populations. READ MORE
