2. 1. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors

   Author : Stéphane Velut; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; Large scale fermentations; Extremum control; Feeding strategy; Probing control; Fed-batch bioreactors; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : In most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. READ MORE

4. 2. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

   Author : Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

   Abstract : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. READ MORE

5. 3. Interface design of biodegradable polyester/nanocellulose biocomposites via reactive melt processing: tailoring of polyester matrix

   Author : Angelica Avella; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aminolysis; cellulose nanocrystals; wet-feeding; crosslinking; poly ε-caprolactone ; biocomposites; reactive melt processing;

   Abstract : Pushed by the societal awareness of plastic pollution, attempts are being made to find sustainable materials that can minimize the environmental impact of plastics. In this context, biocomposites based on biodegradable polymers and renewable lignocellulose are of interest. READ MORE

6. 4. Optimal Railroad Power Supply System Operation and Design : Detailed system studies, and aggregated investment models

   Author : Lars Abrahamsson; Lennart Söder; Arnd Stephan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.

7. 5. Development of mathematical modelling for the glycosylation of IgG in CHO cell cultures

   Author : Liang Zhang; Véronique Chotteau; Michael J. Betenbaugh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chinese hamster ovary cells; glycosylation; IgG; mathematical modelling; experimental design; perfusion; carbon sources; GReBA; Bayesian network; probabilistic graphic model; Bioteknologi; Biotechnology;

   Abstract : Chinese hamster ovary (CHO) cells are the most popular expression system for the production of biopharmaceuticals. More than 80% of the approved monoclonal antibodies (mAbs) or immunoglobulin G (IgG) are produced with these cells. Glycosylation is a usual post- translational modification important for therapeutic mAbs. READ MORE
