Studies conducted with the adult western cherry fruit fly,
Rhagoletis indifferens Curran, revealed that successful oviposition
occurred in three distinct phases, the prepenetration phase, the
penetration phase and the postpenetration phase. During the
postpenetration phase which averaged 51 seconds (range 18 to 86), the
females dragged their ovipositor over the...
The biochemical degradation of domestic sludge deposits exposed to benthic marine conditions was investigated using a laboratory Deep Sea Simulator. The rate and extent of deposit stabilization were determined for select hydrostatic pressures and hydrogen acceptor conditions by monitoring depletion of particulate organic carbon in 2.0 and 3.0 centimeter deposits....
Results of recent studies on Piagetian cognitive development,
though equivocal, showed that the architectonic of formal operational
schemata is not possessed by a sizeable percentage (up to 52%) of adolescents
and young adults. The purpose of the present study is two
fold: (i) To assess the cognitive levels of a...
The objectives of this investigation were two-fold: (1) to examine possible seed and cone characteristics and their usefulness as seed maturity indices, and (2) to examine the effects of artificial ripening on seed maturation and germination. Cone fresh weight, cone length, cone specific gravity, cone color, seed fresh weight, seed...
Preliminary studies with a dog (Canis familiaris) and a coyote
(Canis latrans) showed that these carnivores can serve as definitive
hosts in the life cycle of Sarcocystis fusiformis of cattle (Bos
taurus) and a microscopic Sarcocystis of mule deer (Odocoileus
hemionus hemionus). Preliminary studies to determine effects of the
In this research a model is developed to predict population for relatively
rural areas experiencing rapid economic development. Of the many
ways to predict population size, in this research a "demographic-economic"
model is chosen for use. The economic variables which aid in projecting
population are total employment, and net changes...
Silurian and Devonian rocks are exposed for approximately 8 square kilometers inthe KootenayArc structural province of northeastem Washington. These Middle Paleozoic rocks overlie the Upper Cambrian Metaline Limestone and the Ordovician Ledbetter Formation, which includes slates, siltstones, and limestones. Two Silurian units crop out in this area. Unit A is...
Competition for the conventional supply of wood residue utilized
by the particleboard industry is increasing. Utilization of low
quality residues by the pulp and paper industry, new sawmill and
plywood recovery techniques, and the growing practice of converting
low quality residues into steam and electrical power have all cut into...
