Multiple zeros for eigenvalues and the multiplicity of traps of a linear compartmental system
(Elsevier, 1975)
It is known that a linear compartmental system has a trap if and only if the associated system of differential equations has zero as an eigenvalue. In this paper, we show that if such a system has zero as an eigenvalue of ...
Models of lon and substrate cotransport and the effect of the membrane potential
(Elsevier, 1972-02)
The implications of a carrier model of ion and substrate cotransport are worked out. Each carrier is assumed to have one ion and one substrate binding site. The model includes features that have not been included in ...
Solute concentration in the kidney-- II. input-output studies on a central core model
(Elsevier, 1976)
Input-output studies have been carried out on a central core model of the renal medulla of the rabbit. The results emphasize the importance of having a nontransported solute such as urea. Even though only salt was actively ...
How to determine the compatibility of undirected character state trees
(Elsevier, 1979-10)
Methods for cladistic character compatibility analysis have required a priori estimates of the direction of evolutionary trends among the states of a character, in order to ensure consistency. Results are presented here ...
A global strategy for nonlinear least squares
(Elsevier, 1970-02)
A general strategy for attacking problems in nonlinear least squares is developed. Parameters are classified as linear or nonlinear, depending on whether they appear linearly or nonlinearly in the functional expression ...
Functional differential equations and age dependent population growth
(Elsevier, 1972-08)
Growth equations are established for a population of individuals that have fixed age dependent reproduction and mortality rates. Equations are obtained both for the population density and for the numerical size of the ...
Models for growth kinetics of yeast
(Wiley Subscription Services, Inc., A Wiley Company, 1978-02)
No Abstract.
An initial-value method for the solution of certain nonlinear diffusion equations in biology
(Elsevier, 1970)
The steady-state one-dimensional diffusion equation with a nonlinear source term is a class of differential equations governing the behavior of many biological systems. As with other types of nonlinear differential equations, ...
Post-thaw suspension of red cells cryopreserved with hydroxyethyl starch
(Elsevier, 1978-08)
Post-thaw suspension of red cells cryopreserved with hydroxyethyl starch (HES) gives rise to an increase in the quantity of supernatant hemoglobin and a reduction in cell recovery. This occurs regardless of the suspension ...
Red cells preserved with 10% hydroxyethyl starch: Effect of prefreeze washing
(Elsevier, 1975-10)
Prefreeze washing of red cells with saline and other wash solutions before freezing with 10% hydroxyethyl starch does not yield an improved product after thawing. The saline stabilities and cell recoveries are reduced and ...
