Countercurrent gradient chromatography: A continuous focusing technique
(Wiley Subscription Services, Inc., A Wiley Company, 1995-12-05)
The continuous separation of proteins was performed in a countercurrent gradient chromatography (CGC) system. A magnetically stabilized fluidized bed (MSFB) was used to establish true countercurrent contact of a solid resin ...
A model of the renal cortex and medulla
(Elsevier, 1967)
Mathematical models of the renal cortex and medulla are developed. The glomerular filtration rate is treated as an input parameter. The differential equations for transfer of water and solutes are developed under the ...
Computer modeling of antibiotic fermentation with on-line product removal
(Wiley Subscription Services, Inc., A Wiley Company, 1988-07-20)
The fermentation of Streptomyces griseus for the production of cycloheximide is similar to other antibiotic fermentations in that product synthesis is subject to feedback regulation and the desired product is degraded ...
Exact Results for the Universal Area Distribution of Clusters in Percolation, Ising, and Potts Models
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-01)
At the critical point in two dimensions, the number of percolation clusters of enclosed area greater than A is proportional to A −1 , with a proportionality constant C that is universal. We show theoretically (based upon ...
Alteration of the growth rate and lag time of Leuconostoc mesenteroides NRRL-B523
(John Wiley & Sons, Inc., 2001-03-20)
Bacterial profile modification is an important enhanced oil recovery technique used to direct injected water into a reservoir's low permeability zone containing trapped crude oil. During water flooding, the use of bacteria ...
Formation of polyol–fatty acid esters by lipases in reverse micellar media
(Wiley Subscription Services, Inc., A Wiley Company, 1992-06-05)
The synthesis of polyol–fatty acid esters has strong implications in such industries as foods, cosmetics, and polymers. We have investigated these esterification reactions employing the polyols ethylene glycol, 2-monoglyceride, ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
Hull-generating walks
(Elsevier, 1989-09)
A hull-generating walk (HGW) is a type of kinetic random walk that generates the hull or perimeter of a percolation cluster, and thus has a fractal dimension of 1.75. Some examples of HGWs for site and bond percolation on ...
Use of coimmobilized biological systems to degrade toxic organic compounds
(Wiley Subscription Services, Inc., A Wiley Company, 1991-07)
The concept of coimmobilizing cell mass (and/or enzyme) and adsorbent in a hydrogel matrix for biodegradation of toxic organic chemicals was introduced. Under defined experimental conditions, the coimmobilized system using ...
