A system to perform neutron radiographic analysis of dynamic
events taking place over the order of several milliseconds has been
developed at Oregon State University. The design consists of a TRIGA
reactor capable of pulsing to 3000 MW peak power, a neutron beam
collimator with an L/D of about 30:1,...
Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...
We report results from an oyster hatchery on the Oregon coast, where intake waters experienced variable carbonate chemistry (aragonite saturation state < 0.8 to > 3.2; pH < 7.6 to > 8.2) in the early summer of 2009. Both larval production and midstage growth (∼ 120 to ∼ 150 µm)...
The present study examined fathers' and mothers' attitudes
toward fathering and fathers' involvement with their infant sons
and daughters. Subjects included 42 pairs of parents with infants
from upper and middle socioeconomic class families. All subjects
were of the Caucasian race. The Attitudes Toward Fathering Scale
and the Father Behavioral...
Current research in the area of two-phase flow utilizes
a wide variety of sensing devices, but some limitations exist
on the information which can be obtained. Neutron radiography
is a feasible alternative to "see" the two-phase flow.
A system to perform neutron radiographic analysis of dynamic
events which occur on...
Neutron shadow holography is a method of obtaining a
three-dimensional neutron radiograph of an object using a
Fresnel zone plate as an encoding aperture. The object is
reconstructed by passing laser light through a miniature
copy of the radiograph. The technique has been applied
extensively with X-rays and gamma rays...
Sequence-specific PCR markers were derived from one new and eight previously identified random amplified polymorphic DNA (RAPD) markers for the purpose of identifying grape (Vitis) rootstocks. The markers were developed because the RAPD assay was found to be inconsistent and the original RAPD markers unreliable. Southern hybridization analysis of the...
The histopathological and histochemical effects on the snail
Oxytrema siliqua, caused by the larvae of Nanophyetus salmincola,
have been studied. The parasite causes damage to the organ by increased
pressure, active ingestion of the hepatic tubules, and by
the increased burden placed upon the snail in disposing of the waste...
