Coagulation equations with gelation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1983-06)
Smoluchowski's equation for rapid coagulation is used to describe the kinetics of gelation, in which the coagulation kernel K ij models the bonding mechanism. For different classes of kernels we derive criteria for the ...
Computer aided analysis for biosensing and screening
(Wiley Subscription Services, Inc., A Wiley Company, 1988-02-20)
Biosensors with animal and microbial cells immobilized close to the tip of a membrane electrode have been developed for chemical and drug testing. Our experimental results show that biosensors can be used for drug screening ...
Fermentation monitoring by polymeric-resin-based microbiol assay
(Wiley Subscription Services, Inc., A Wiley Company, 1983-03)
A polymeric-resin-based microbiological assay is shown to yield results consistent with classical inhibition zone theory. This novel assay is applicable to cycloheximide, an antifungal antibiotic, at concentrations below ...
Cell immobilization in k -carrageenan with tricalcium phosphate
(Wiley Subscription Services, Inc., A Wiley Company, 1982-08)
The objectives of this research were to investigate the growth of immobilized yeast cells in k -carrageenan gel and study the effect of trapping hydroxyapatite (tricalcium phosphate) crystals into the matrix. Using k ...
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 ...
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 ...
A new isolation and purification method for staphylococcal protein A using membrane encapsulated rabbit IgG-agarose
(Wiley Subscription Services, Inc., A Wiley Company, 1989-10-20)
A new isolation and purification method for bioproducts using membrane-encapsulated affinity adsorbents was investigated. The new method involves encapsulation of affinity adsorbents, batch adsorption of the bioproduct ...
Protein release from Escherichia coli cells permeabilized with guanidine–HCl and Triton X100
(Wiley Subscription Services, Inc., A Wiley Company, 1989-02-20)
An important factor complicating the recovery of recombinant proteins from Escherichia coli is their intracellular location. An alternative to the commonly used method of releasing these proteins by mechanical disruption ...
Interaction of infectious viral particles with a quaternary ammonium chlorid (QAC) surface
(Wiley Subscription Services, Inc., A Wiley Company, 1989-08-20)
The antiviral activity of a surface-bonded quaternary ammonium chloride (QAC) was examined in this study. The mechanism of inactivation was elucidated by a combination of infectivity assay, radioactive labeling assay, and ...
Analysis of plane extrudate-swell of highly elastic liquids with molecular constitutive equations
(Elsevier, 1989)
Plane, two-dimensional, polymer extrusion is analyzed by means of the Curtiss-Bird integral constitutive equation, streamlined finite-elements and Newton iteration. The Reynolds number is zero, the surface tension negligible ...
