The development of new electronic devices and design procedures
applicable to ternary switching circuits suggests that it might be desirable
to use ternary arithmetic in direct digital control systems.
The advantages of decimal, binary, and ternary arithmetic in digital
computers are discussed and a set of rules for signed -digit...
Shoot apex senescence is defined as the collective progressive
and deteriorative processes which ultimately terminate the functional
life of the shoot apex. Senescence of shoot apices of Pisum sativum
L. 'Alaska' as measured by cessation of stem elongation was delayed
by removal of flowers and by treatment with gibberellin A₃...
Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln,
and Suffolk) were found to possess two hemoglobin types (Hb. A
and Hb. B) when their hemoglobins were examined by disc gel electrophoresis.
The hemoglobin alleles proved to be co-dominant.
Three of the breeds (Columbia, Targhee, and Rambouillet)
were maintained at altitudes...
Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears
picked at different degrees of maturity were treated with Ethrel
(2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm,
for different lengths of time. Respiration rate was measured twice
daily and changes...
More than 4,000 specimens of fruits and seeds were extracted
from the matrix removed from inside the skulls of sabre-tooth cats
excavated from various pits in the Rancho La Brea deposits. Of this
number, spproximately 1,445 specimens are involved in this study.
Many comparisons with modern fruits and seeds made...
The objective of this study was to compare the total collection
(in vivo), nylon bag, and in vitro digestibility techniques under
standardized conditions. Twin steers were used simultaneously to
measure the digestibility of five rations consisting of the following
ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...
A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central
Oregon. The <2 μ size fraction from each sample was characterized
with respect to the relative significance of amorphous and
crystalline components, and the individual minerals of the latter
group were...
