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...
Investigations were conducted to determine the nature, type,
functional properties and the amounts of different proteins found in
bovine rumen tissue.
Data concerning the effect of pH and salt concentration on
the extractability of proteins from rumen tissue indicated that 92%
of the proteins could be extracted in aqueous solutions...
The effect of ultra-high pressure on the thermal emf of a
chromelialumel thermocouple is investigated using an indirect
method which does not require a direct knowledge of the temperature
of the pressurized junction. The unknown temperature is written
parametrically as a function of a directly measured quantity, the
electrical power...
An evaluation of fabric reinforcement of the roadway
structure is made. The study includes a parametric analy
sis using layered elastic theory and a series of large
scale model tests.
The parametric. study analyzes the stresses and
strains of roadway structures with a fabric layer between
tna surface layer and...
A technique previously designed to screen wheat cultivars and
segregating populations for tolerance to Aluminum utilizing nutrient
solutions in growth chambers was found to be efficient in differentiating
among cultivars of wheat, rye, and triticale for tolerance to Al
under greenhouse conditions. A 5°C increase in temperature, from
25°C to...
The distribution in Oregon of two viruses affecting salmonid
fishes was determined by examination of hatchery and feral fish.
Infectious pancreatic necrosis virus (IPNV) was isolated from fish
at the Oregon Department of Fish and Wildlife Research Laboratory,
Corvallis, Roaring River, Fort Klamath, and Wizard Falls Hatcheries.
Fish collected at...
