Migration of anchorage-dependent mammalian cells
Cell migration affects many physiologic and pathologic processes in mammalian organisms. Thus, our ability to modulate these processes depends on understanding how cell migration is controlled by soluble factors, cell-substrate ...
Dynamics of plasmid-containing cells in a chemostat under transient conditions
One of the major concerns in the utilization of plasmid-containing organisms in fermentation processes is the stability of the plasmid. In general, it is observed that two parameters, the probability of plasmid loss due ...
The constitution of silica gel
Abstract Not Available.
Stress as a means to enhance secondary metabolite productivity and to probe metabolic pathways
The objectives of this research were to study metabolic pathways in C. roseus hairy root cultures, and to enhance secondary metabolite productivity using fungal elicitation as the technique. The effects of age of inoculum ...
Modeling and simulation of monolith reactors
Monolith reactors are studied with models and simulations, with particular attention given to the catalytic converter. It is found that previously noted differences between one- and two-dimensional monolith reactor models ...
The application of digital image analysis techniques to studies of lymphocyte function
Video microscopy and digital image analysis methods were developed for studying immune cell function. Firstly, fluorescence energy transfer spectroscopy was used to monitor the evolution of the intercellular contact area ...
Anaerobic digestion process control using a knowledge-based system
Much attention has been devoted to the design and construction of wastewater treatment plants. However, relatively little attention has been devoted to plant operations. Knowledge based or expert systems are oriented toward ...
Hydrodynamic mechanisms of cell damage in microcarrier bioreactors
A stirred microcarrier bioreactor contains a variety of local fluid dynamic environments, including isotropic turbulence, boundary layers, and vortices trailing from the impeller blades, all of which are superimposed on a ...
Growth and injury of freely suspended animal cells in an agitated and surface-aerated bioreactor
The mechanism of animal cell damage due to agitation and aeration in a stirred bioreactor and the effect of media components on cell damage were investigated. Hybridoma cells ATCC CRL-8018 were grown in controlled bioreactors ...
