Solute concentration in the kidney-- I. a model of the renal medulla and its limit cases
(Elsevier, 1976)
We develop a general model of the renal medulla that is similar in geometry to the models reported by others. Two solutes are assumed to be present, one to play the role of salt and the other that of urea and similarly ...
Quantitative evaluation of the pH profile in organic acid fermentations

Export Production in the Subarctic North Pacific over the Last 800 kyrs: No Evidence for Iron Fertilization?
(Kluwer Academic Publishers; The Oceanographic Society of Japan ; Springer Science+Business Media, 2004-01)
The subarctic North Pacific is a high nitrate-low chlorophyll (HNLC) region, where phytoplankton growth rates, especially those of diatoms, are enhanced when micronutrient Fe is added. Accordingly, it has been suggested ...
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 ...
Incentivizing sustainable development: The impact of a recent policy reform on electricity production efficiency in China
(Wiley Periodicals, Inc.Springer, 2019-07)
China’s rapid economic growth has tremendously accelerated its energy use, calling for a more sustainable supply of scarce and nonrenewable energy. Using a firm‐level dataset of 30 major Chinese electricity utilities from ...
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 ...
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 ...
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 ...
Reproduction numbers and thresholds in stochastic epidemic models I. Homogeneous populations
(Elsevier, 1991-12)
We compare threshold results for the deterministic and stochastic versions of the homogeneous SI model with recruitment, death due to the disease, a background death rate, and transmission rate [beta]cXY / N. If an infective ...
