4. 3. Effects of dietary fibre on the human metabolism and metabolome

   Författare :Anna Johansson Persson; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arabinoxylan; b-glucan; dietary fibre; inflammation; LC-MS; metabolomics; oat; pectin; postprandial response; randomised controlled trial; rye; sugar beet fibre;

   Sammanfattning : It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. LÄS MER

5. 4. Formation and properties of polyelectrolyte multilayers on wood fibres : influence on paper strength and fibre wettability

   Författare :Rikard Lingström; Lars Wågberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; Chemistry; Kemi;

   Sammanfattning : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. LÄS MER

7. 5. Renewable Composites Prepared from Biobased Thermoset Resins

   Författare :Dan Åkesson; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin;

   Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER
