Attempts were made to study the effect of parathion and DDT
on the postnatal development of mice. Parathion, DDT or corn oil
(control) was administered to gravid mice during the first, second,
and third trimesters of pregnancy. Thus, nine groups of offspring
were obtained. Four different techniques, Audiogenic Seizure,
Conditioned...
It is common to characterize adrenergic receptors by placing
them in one of two categories, alpha or beta. The receptors responsible
for adrenergically induced increase in cardiac contractile force
and glycogenolysis are usually classified as beta receptors, but such
a classification is not definitely established. Therefore, an attempt
was made...
Virus contamination in a potato breeding program can seriously
disrupt the variety development process. Experiments were conducted
from 1989 through 1993 to: evaluate the extent to which Potato
Leafroll Virus (PLRV) and Potato Virus Y (PVY) can invade a breeding
program, determine viral spread within hills and within individual
tubers,...
There are many different types of automatic data collection technologies that have been used in transportation system applications such as pneumatic tubes, radar, video cameras, inductive loops detectors, wireless toll tags, and global positioning systems (GPS). Nevertheless, there are still multiple examples of important and helpful transportation system data that...
Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of
33 dominant species that occurred in the National Marine Fisheries Services' triennial
trawl surveys over the continental shelf and upper slope off California, Oregon, and
Washington from 1977 to 1992. The assemblages accounted for about 70% of the total...
The last decade has seen a drastic interest in microgrids throughout the world. Even though this trend might seem to be just another technological solution in the energy sector, it is a part of a greater transition from a centralized energy system to a more decentralized one. However, unlike most...
Two types of temporary poois, known as playas, occur in semiarid southeast Oregon. Vegetated upland playas are found in the High Lava Plain province; barren alkaline-saline playas are found in the Basin and Range province. Both types become ponded in most years, but they often lack redoximorphic features indicative of...
Teamwork has become a popular operational strategy applied as part of workforce management plans in manufacturing and service industries. Teamwork has been commonly used in organizations to pursue different goals such as increase business operations agility, boost company productivity, improve quality in operations, increase company flexibility, promote collaborative learning, hasten...
Biologists have long been fascinated with reproductive traits, in part because they are frequently exaggerated or showy, and they commonly vary among closely related species. Exaggerated sexual traits, in particular, have been the focus of intense empirical and theoretical research, but most of this work has focused on traits involved...
