Significant reductions in the number of defects in parts
produced by investment casting can be obtained by improving
the flow of the molten metal during pouring. Studies have
been done at Oregon State University with simulated casting
techniques to determine optimal mold configurations.
Better mold layouts have been shown to...
Pollutant body burdens, ability to tolerate supplementary stressors, and
biomarkers of physiological stress were investigated in the ground beetle,
Pterostichus oblongopunctatus (Coleoptera: Carabidae), inhabiting a gradient
of heavy metal contamination in Poland. The central question was to
determine if beetles inhabiting polluted habitats incurred costs compared with
beetles in less...

To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...
An attempt was made to create a hormonal environment of the
uterus comparable to that near the time of natural laying and to
eliminate the effect of a hard-shelled egg on fertilization. Hens without
hard-shelled eggs in their uteri were injected with the posterior
pituitary hormones, oxytocin and arginine vasopressin,...
In today’s world, we are highly dependent on software systems together with devices for almost every task in our day to day life. Software system upgrades are released whenever it is necessary to accommodate the ever-changing user’s needs. The devices we use to run the software systems might be of...
Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
With increased resource development on the western Arctic coastal plain of Alaska
(especially within the oil extraction industry) it is important to understand the basic
life history attributes of whitefish stocks in the region in order to ensure appropriate
management. These fish are a crucial part of subsistence harvests for...
