  1. 16. Development of a protein-free fed-batch process for NS0 cells: studies on regulation of proliferation

    Författare :Erika Spens; Lena Häggström; Jean-Louis Goergen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NS0 myeloma cells; protein-free medium; fed-batch; conditioned medium; autocrine growth factors; abortive proliferation; protease activity; aprotinin; gp130; Bioengineering; Bioteknik;

    Sammanfattning : The overall objective of this study was to investigate how NS0 cell proliferation is regulated in protein-free media. The hypothesis was that during the adaptation to growth factor-free media, animal cell lines start to produce their own autocrine growth factors to support proliferation, and after some time in a culture the effects of these factors are lost which results in cessation of proliferation.

  3. 17. Physiology of Caldicellulosiruptor saccharolyticus: a hydrogen cell factory

    Författare :Karin Willquist; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; growth activation; hydrogen tolerance; hydrogen yields CO2 inhibition; physiology; enzyme kinetics; Caldicellulosiruptor saccharolyticus; biohydrogen; energy metabolism;

    Sammanfattning : A high substrate conversion efficiency is a prerequisite for an economically feasible biohydrogen production. Caldicellulosiruptor saccharolyticus is a strictly anaerobic extreme thermophilic bacterium that is able to convert the theoretical maximum of 4 mol/mol glucose to H2. LÄS MER

  4. 18. Cognitive work analysis in practice : Adaptation to project scope and industrial context

    Författare :Ida Bodin; Anders Jansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : The Cognitive Work Analysis (CWA) framework is widely used by researchers for the analysis of complex systems. It, however, lacks the same impact amongst industrial practitioners. This thesis investigates possible adaptations of the framework to project and industrial constraints, and the consequences associated with such adaptations. LÄS MER

  5. 19. Process development for combined pentose and hexose fermentation

    Författare :Fredrik Nielsen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioethanol; Lignocellulose; Xylose fermentation; Co-fermentation; Process design; Agricultural residues; Saccharomyces cerevisiae;

    Sammanfattning : Second-generation ethanol from lignocellulose is a sustainable alternative that can partially replace fossil fuels. To be competitive with first generation ethanol from sugar and starch crops and fossil fuels, the conversion efficiency and ethanol yields of second-generation ethanol conversion processes must be improved.

  7. 20. Switched Real-Time Ethernet for Industrial Applications

    Författare :Hoai Hoang; Magnus Jonsson; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Switched Ethernet; Real-time communication; EDF scheduling; Industrial networks;

    Sammanfattning : The research reported in this thesis has been focused on developing and analyzing how to support real-time traffic over a switched Ethernet network without any hardware or protocol modifications. The work has resulted in a proposed systems model, supporting both real-time and non real-time traffic. LÄS MER
