1. Perturbation-based Control of Industrial Fed-batch 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. Probing Control of Glucose Feeding in Escherichia coli Cultivations
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. The stochastic nature of intracellular control circuits
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. Psychological factors and metabolic control in insulin-dependent diabetes mellitus
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. Perioperative glucose control
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.
