Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
On the dynamic order of structured Escherichia coli growth models
(Wiley Subscription Services, Inc., A Wiley Company, 1987-04-20)
Reliable dynamic descriptions of cellular growth are important for many practical applications including bioreactor design and control. A chemically structured growth model of Escherichia coli has been formulated and ...
Confidence intervals with fixed proportional accuracy
(Elsevier, 1986-1987)
The problem of setting a confidence interval with fixed proportional accuracy for the mean of a normal distribution is considered. A sequential procedure is proposed; and asymptotic expansions for its average coverage ...
Singh's theorem in the lattice case
(Elsevier, 1988-12)
The asymptotic behavior of the parametric bootstrap estimator of the sampling distribution of a maximum likelihood estimator is investigated in a simple lattice case, integer valued random variables whose distributions ...
Density estimation with Haar series
(Elsevier, 1990-02)
Rate of convergence for density estimators based on Haar series are derived under very mild condition: the unknown density has to be of bounded variation. These estimators are histograms on dyadic intervals.
Experimental and mathematical modeling studies of protozoan predation on bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1973-07)
The predation of bacteria by protozoan in both continuous and batch cultures was studied using experimental and modeling techniques. The predator organism was the ciliate, Tetrahymena pyriformis. The bacterium, Aerobacter ...
Comments on rarity and chaos, Thomas D. Rogers, math. biosci. 72:13-18 (1984)
(Elsevier, 1985-03)
On performing experimental studies on transient states of continuous-flow methanogenic reactors
(Wiley Subscription Services, Inc., A Wiley Company, 1990-03-25)
One approach to exploring the behavior of microbial cultures during transient conditions of unbalanced growth is to experimentally observe continuous-flow biological reactors which have been subjected to perturbations in ...
On the renewal measure for Gaussian sequences
(Elsevier, 1986-06)
A form for U(t), the expected number of times a Gaussian sequence falls below a level of t, is given in terms of the mean M(x) and the variance V2(x) functions. It is shown that under general conditions U(t) ~ M(-1)(t), t ...
