Quantitative evaluation of the pH profile in organic acid fermentations
(Wiley Subscription Services, Inc., A Wiley Company, 1991-01-20)
No Abstrct.
Eco-ethics as the foundation of conservation
(Elsevier, 1984)
SummaryEnvironmental ethics must be distinguished from ecological ethics. While the former concerns itself with the appropriate management of natural resources and is often guided by cost-benefit analysis, the latter ...
A generalization of the Goldman equation, including the effect of electrogenic pumps
(Elsevier, 1971-10)
An equation similar to the Goldman equation is derived for the steady-state diffusion of univalent ions across a membrane with arbitrary potential profile and in the presence of electrogenic pumps. The presence of electrogenic ...
Wet and dry deposition of phosphorus into Lake Huron
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1978-08)
The deposition rates for wet, dry, and integrated fallout of P to the southern portion of Lake Huron were determined. Samples were analyzed for water-soluble, acid (pH =2) soluble, and insoluble (bound) P. The term ‘available ...
Selective extraction using preferential transport through adsorptive membranes
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-05)
Selective extraction of a protein from a mixture can be accomplished using an adsorptive membrane and low displacement recuperative parametric pumping. Low displacement recuperative parametric pumping can lead to the ...
Data subset selection by Boolean calculation
(Elsevier, 1984-11)
In this journal in 1969 the authors described an unconventional method, based on concepts from systematic biology, for storing and retrieving data, whose salient features are: (1) data are stored in such a manner that the ...
PCB uptake and transfer to humans by lake trout
(Elsevier, 1984)
A mathematical model for contaminant uptake from food and water by fishes is combined with a model for yield as a function of fishing mortality in order to examine both the contaminant concentration in fishes and the amount ...
A reaction-diffusion system of a predator-prey-mutualist model
(Elsevier, 1986-04)
Mutualism is part of many significant processes in nature. Mutualistic benefits arising from modification of predator-prey interactions involve interactions of at least three species. In this paper we investigate the ...
Modelling the effect of acidity on mercury uptake by walleye in acidic and circumneutral lakes
(Elsevier, 1988)
An association between acidification of lakes and high mercury concentrations in fishes has been reported. In northern Wisconsin (USA), for example, walleye (Stizostedion vitreum) in naturally acidic lakes have higher ...
Primary rat hepatocyte culture on 3D nanofibrous polymer scaffolds for toxicology and pharmaceutical research
(Wiley Subscription Services, Inc., A Wiley Company, 2011-01)
Primary rat hepatocytes are a widely used experimental model to estimate drug metabolism and toxicity. In currently used two-dimensional (2D) cell culture systems, typical problems like morphological changes and the loss ...
