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...
A study to determine the relationship between plant species and eight terrain variables and between thirty-one vegetation types
and the terrain variables was conducted in a 4, 000 square mile area
south and east of Tucson, Arizona. The eight terrain variables
included elevation, parent material, macrorelief, landform type,
drainage density,...
The primary purpose of this study was to explore the relationships
between the variables of sex, age, sibling status, age relationship
of sibling, age spacing between siblings and sex-role preference among
preschool-aged children.
Seventy-one children, 32 boys and 39 girls, ranging in ages
from two-years-eleven-months to five-years-seven-months, served
as subjects....
The purpose of this investigation is to explore research management
problems pertaining to types of research where direct outputs are
in terms of intangible ideas or the kind of knowledge which takes years
to be proven applicable or economically fruitful.
The study was based on the analysis of the more...
Injection of a 2.0 mg Cd

in
.05 M NaAc, pH = 6.9-7.2, .15 M or p = .15 with NaCl) resulted
in a decrease in ceruloplasmin (EC 1.12.3) p-phenylenediamine
oxidase activity within one hour of injection.
Maximal decrease (40%) occurred within six...
Carrots cooked by microwaves were judged less tender in both
the core and external flesh area than those cooked by conventional
boiling. Broccoli cooked by microwaves was less tender in the
external layer but softer in the central flesh than that cooked conventionally.
Cooking methods made essentially no difference in...
Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow
trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to
Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy
confirmed the microsomal...
