Employing compensators which adapt to errors in system components
is one way of meeting the increasingly tight specifications of
modern control systems. Indeed this is often the only way that such
specifications can be met in systems with unchangeable or best available
parts. One type of error found in components...
Seed yield in perennial ryegrass is the product of yield components
that develop during the life of the plant. Crop yield potential is
defined by the number of fertile tillers, spikelets per spike, and
florets per spikelet. It has been shown that perennial ryegrass
realizes only a small percentage of...
The Virgin Valley-McGee Mountain area is located in the northwest
corner of Nevada in the northwestern part of the Basin and
Range structural province.
Rocks within the area consist predominantly of Miocene to
Pleistocene volcanic rocks and volcanic derived sedimentary rocks.
The volcanic rocks include rhyolite, rhyolite welded tuffs, and...
Cultural and developmental characteristics of a collection of
Anthracobia melaloma with a brown hymenium and a barred exterior
appearance were examined. It grows well in culture on CM and
CMMY agar media and has a growth rate of 17 mm in 18 hours. It is
heterothallic and produces asexual multinucleate...
The focus of this study was to identify persistent
problems in the developmental history of the American
Department of Defense dependents schools in Okinawa, Japan.
The period of time covered was from 1946 through 1978.
The study includes historical descriptions of curriculum
development, obtaining and maintaining school facilities,
and the...
A taxonomic revision of the genus Anthracobia Boudier is
presented. The genus and eight included taxa are described and
figured. A discussion of the taxonomic criteria used to delimit the
genus and the species is included, and a key to the recognized taxa is
given. Four imperfect states for included...
Laboratory studies were conducted to evaluate the effects of prey
availability on prey consumption, survivorship and oviposition of the
southern pine beetle predator, Thanasimus dubius Fabricius. Although
prey consumption rates were significantly affected by the sex, size and
ovipositional status of the predator, it was found through correlation
analyses that...
