  1. 1. Perturbation-based Control of Industrial Fed-batch Bioprocesses

    Författare :Ola Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perturbation-based control; process control; fed-batch control; industrial bioprocesses;

    Sammanfattning : The topic of this thesis is bioprocess control, more specifically control of industrial-scale microbial fed-batch bioprocesses. Its focus is therefore on methods which are easy to implement in an industrial setting, which gives certain limitations on sensors, actuators and control systems. LÄS MER

  2. 2. Probing Control of Glucose Feeding in Escherichia coli Cultivations

    Författare :Mats Åkesson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; dissolved oxygen; acetate; glucose feeding; robotteknik; Escherichia coli; Process control; fed-batch cultivation; reglerteknik; Biotechnology; Bioteknik;

    Sammanfattning : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. LÄS MER

  3. 3. The stochastic nature of intracellular control circuits

    Författare :Johan Paulsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Stochastic; mesoscopic; noise; gene; plasmid; metabolic; regulation; control; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Chemical reactions are probabilistic by nature, causing random fluctuations inconcentrations to emerge spontaneously. In conventional (macroscopic) kinetics this internal noise is ignored under the assumption that average copy numbers are so high that fluctuations are negligible in comparison. LÄS MER

  4. 4. Psychological factors and metabolic control in insulin-dependent diabetes mellitus

    Författare :Ulf Stenström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Insulin-dependent diabetes mellitus; social support; gender; age; long-term complications; metabolic control; quality of life; well-being; insulin-pen treatment; coping; life events; locus of control beliefs; longitudinal; Applied and experimental psychology; Tillämpad och experimentell psykologi;

    Sammanfattning : This doctoral thesis consists of six studies concerning persons with insulin dependent diabetes mellitus (IDDM). The first two deal with relationships between life events, social support and metabolic control (HbA1C) over a two year period. For the female subjects, results obtained for this period were inconsistent. LÄS MER

  5. 5. Perioperative glucose control

    Författare :Christina Blixt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Trauma or surgery elicit a physiological stress response, which among others induces insulin resistance. It could be described as a state where the biological response to a given dose of insulin is reduced, and is associated with an altered glucose metabolism, as well as a disturbed lipid and protein metabolism and dysfunctional immune, inflammatory and coagulation systems.
