Effects of food limitation and emigration on self-thinning in experimental minnow cohorts
Autor: Jason B. Dunham, Gary L. Vinyard, R. D. Duncan, B. R. Dickerson, Erik A. Beever
Publikováno v: Journal of Animal Ecology. 69:927-934
Summary 1. The theory of food-regulated self-thinning (FST) for mobile animals predicts population density (N) to be an inverse function of mean body mass (W) scaled to an exponent (b), such that N = k W−b, where k is a constant. FST also predicts

Congenital convex pes valgus
Autor: R D, Duncan, J A, Fixsen
Publikováno v: The Journal of bone and joint surgery. British volume. 81(2)
Congenital convex pes valgus (congenital vertical talus) is a rare condition. We reviewed ten feet in seven patients who had had surgical correction. All had been operated on by the senior author (JF) and the same surgical technique was used througho

Correcting hot-wire measurements of stream-wise turbulence intensity in boundary layers
Autor: Peter A. Monkewitz, R. D. Duncan, Hassan M. Nagib
Publikováno v: Physics of Fluids. 22:091701
The current experimental activity aimed at resolving the scaling of stream-wise turbulence intensity profiles uu¯+(y+) with Reynolds number in turbulent flat plate boundary layers has brought the largely unresolved issue of correcting systematic err

Paper Chromatographic Determination of Phosphorus Species
Autor: R D Duncan, Louis A. Stumpe, Joe R Trimm, J. E. Lawrence, Frank J Johnson
Publikováno v: Journal of AOAC INTERNATIONAL. 63:859-863
Ascending paper chromatographic methods are described to identify and quantify phosphorus species present in polyphosphates, metaphosphates, fluorophosphates, and phosphites. After interfering cations are removed or complexed, samples are chromatogra

A Critical Evaluation of the Ammonium Molybdophosphate Method for Phosphorus
Autor: J A Srabson, R D Duncan
Publikováno v: Journal of AOAC INTERNATIONAL. 48:1092-1095
The official ammonium molybdophosphate method for phosphorus is subject to both positive and negative errors. The solubility of the precipitate in the precipitation medium is negligible, but its solubility in water is high enough to introduce signifi
