Volumetric displays allow users to view freely three-dimensional (3D) imagery without special eyewear. However, due to low display resolution, many colors appear distorted compared to their representation on a flat-panel display. In addition, due to

A simple micromethod for serum inorganic phosphorus determination is described. Its reproducibility, accuracy, and nominal cost make its use particularly valuable in research laboratories where small sample size is mandatory. There is less variation

Tests of citrus seedlings exposed to a series of hardening temperatures showed that kumquat, Fortunella hindsii (Champ.) Swing., acquired more hardiness at 21°/10°C than did ‘Redblush’ grapefruit, Citrus paradisi Macf., or citron, C. medica L.

A nonparametric test of dispersion with paired replicates data is described which involves jackknifing logarithmic transformations of the ratio of variance estimates for the pre- and post-treatment populations. Results from a Monte Carlo simulation s

The mathematical model which underlies Hamilton's R-factor ratio test is shown to be inappropriate for determining molecular structure by lanthanide shift reagents for the following reasons. There is uncertainty in the degrees of freedom associated w

1. This investigation was designed to determine whether the appearance and growth of the ys1 mutant in maize were related to its iron or magnesium metabolism. 2. No differences were observed in iron or magnesium concentrations of yellow interveinal a

1. The yellow-stripe maize mutant (ys1) resembles maize plants grown on iron-deficient or low-iron media. Homozygous recessive ys1/ys1 plants have been shown to respond to various iron sources differently than do plants carrying at least one dominant
