  1. 16. Biobased production of succinic acid by Escherichia coli fermentation

    Författare :Christian Andersson; Gen Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). The present thesis illustrates different aspects of biobased succinic acid production by a metabolically engineered E. coli strain. LÄS MER

  3. 17. Effect of Degree of Cure on Viscoelastic Behavior of Polymers and their Composites

    Författare :Sibin Saseendran; Janis Varna; Anders Sjögren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viscoelasticty; Curing; Epoxy; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Reinforced polymer composites consist of continuous fibers embedded in a polymer matrix. The matrix is usually a thermoplastic or thermosetting resin. LÄS MER

  4. 18. Some Basic Problems in Rock Breakage by Blasting and by Indentation

    Författare :S.Q. Kou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : This thesis is devoted to discussing some basic problems in rock breakage by blasting and by mechanical excavation, and contains a detailed summary and six appended papers numbered as Papers A to F. The central problem treated in this thesis is the interaction between either explosion products or mechanical tools and rock. LÄS MER

  5. 19. Integration of a hemicelluloses extraction step into a forest biorefinery for production of green chemicals

    Författare :Jonas Helmerius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : Sustainable use of forest and agricultural resources will play an important role for solving urgent global challenges such as the enhanced green house effect and increasing demand for fossil fuels. The development of processes where lignocellulosic biomass can be refined to several different end-products in the same plant, i.e. LÄS MER

  7. 20. Succinic acid production using metabolically engineered Escherichia coli

    Författare :Christian Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. LÄS MER
