Time-optimal batch diafiltration
This study concentrates on time-optimal operation of a general batch diafiltration process. The process model consists of a set of input affine differential equations. We apply Pontryagin’s minimum principle to formulate necessary conditions of optimality. These are then used to identify the shape of optimal control as well as singular surface in concentration space. Comparison is made between ...

The vertebrate central nervous system contains a great diversity of neurons and glial cells, which are generated in the embryonic neural tube at specific times and positions. Several classes of transcription factors have been shown to control various steps in the differentiation of progenitor cells in the neural tube and to determine the identity of the cells produced. Recent evidence indicates...
متن کاملDiafiltration (Buffer Exchange) Using Hollow Fiber Membranes instead of Dialysis Tubing - Automated Diafiltration
Diafiltration is term used reflecting tangential flow filtration (TFF) method of “washing” or removing a permeable molecule (impurities, salts, solvents, small proteins, etc) from a solution in an accelerated method when compared to dialysis tubing. By selecting the appropriate membrane(s), it can also be used to exchange buffers, narrow particle size distributions, modify salt concentrations o...
متن کاملDiafiltration for Desalting or Buffer Exchange
Diafiltration is an ultrafiltration membrane technique for completely removing, replacing, or lowering the concentration of salts or solvents from solutions containing proteins, peptides, nucleic acids, and other biomolecules. The process selectively uses permeable (porous) membrane filters to separate the components of solutions and suspensions based on their molecular size. Smaller molecules ...
متن کاملWeb Mash - ups
ABSTRACT Context Mash-ups are a new generation of Web-based applications which aggregate and stitch together third-party data. A mash-up usually comprises of unusual or innovative composition of content which is often collected or obtained from unrelated data sources. This data is then displayed in a format suitable for easy human consumption. This form of representation can often lead to comme...
