Seven in vitro trials were conducted to compare the effects of
soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH),
potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium
formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM)
was the criterion used to measure treatment response. A 3 x 3...
An experiment was designed to simulate field conditions of tansy
ragwort poisoning in cattle and horses.
Four calves and four ponies were fed pelleted feed containing 5%
Senecio jacobaea and two ponies and two calves were used as controls.
The feeding continued for two months. Following this, the chronic
delayed...
An experimental investigation was conducted for natural convection
heat transfer in an array of uniformly heated vertical cylinders
in mercury. The test section consisted of seven electrically heated
cylinders of 1.365 inch diameter and 3.825 inch heated length
arranged in an equilateral triangular pattern. In order to preclude
side flow...
An unique opportunity to investigate wind flow
patterns and calm air patterns arose from the acquisition
of a survey by Clarence L. Smalley on air flow patterns in
the San Francisco Bay area from 1952 through 1955. An
analysis was made of the wind patterns and calms in the study...
The genus Ochodaeus Serville contains approximately sixty
species and is World wide in its distribution. One-half of these
species are known from the Nearctic and Neotropic regions.
Adults of six previously described species common to the
United States have been studied in detail. The mandibles, stridulatory
peg, and male genitalia...
The cytoplasmic isozyme of malate dehydrogenase (s-MDH) has been isolated from brine shrimp nauplii to a state of high purity with a protocol involving ammonium sulfate fractionation and chromatography on DEAE-cellulose, followed by sequential passes over cellulose phosphate columns at pH 5.8 then 5.0. The purified enzyme is free of...
Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
