  1. 21. Bovine milk microbiota - methods matter

    Författare :Josef Dahlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The idea of a bacterial community, a microbiota, in milk with the purpose of inoculating the offspring's intestine for a better start in life is very appealing from an evolutionary perspective. The overall purpose of this thesis was to investigate if such bacterial community exists in bovine milk from healthy individuals and to describe factors that affect the microbiota. LÄS MER

  5. 24. Structure and Mechanical Behaviour of Wood-Fibre Composites

    Författare :Thomas Joffre; E. Kristofer Gamstedt; Stéphane Avril; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Wood fibres have several advantages compared to man-made synthetic fibres: they have high specific stiffness, are renewable, relatively inexpensive, available in industrial quantities and biodegradable. However, to increase and diversify their utilisation, it is necessary to increase the understanding on what controls their mechanical properties. LÄS MER

  7. 25. Preparation and Characterization of Macroporous Cryostructured Materials

    Författare :Harald Kirsebom; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Macroporous hydrogels are regarded as interesting materials both within biotechnology and biomedicine due to their properties. These materials can be prepared from a wide range of synthetic or naturally occurring compounds using a number of different techniques for their production. LÄS MER
