The objectives of this study were to evaluate the feeding value
and potential toxicity of single cell protein (SCP) when fed to
ruminants.
Three in vivo digestibility trials with lambs, one feedlot trial
with steers and one long term feeding trial of high levels of SCP with
sheep were conducted...
Probability-based reliability methods have placed an increased emphasis on realistic simulation of structural behavior in bridge engineering. Uncertainty is present in every aspect of structural analysis. Aleatory uncertainties in the loading and load-carrying capacities, and epistemic uncertainties in mathematical idealization of bridge systems are the major contributors to uncertain structural...
Bunt or stinking smut is a major disease of wheat. In the U.S.
common bunt, Tilletia caries (DC) Tul. and T. foetida (Wallr) Liro,
is a threat to wheat production in the Pacific Northwest. Screening
trials conducted by USDA Cereal Investigations Project in Oregon,
from 1955-1980, revealed that a number...
The effect of defoliation intensity and season on Douglas-fir growth
were studied in three replications in the Siuslaw National Forest during
1988-1990. Four intensities of defoliation were applied once in either spring or
summer 1988. Stem diameter and canopy area were linearly inversely
proportional to the level of defoliation. Defoliation...
Studies on net carbon exchange, ¹⁴
C assimilation, and growth
analysis were done on four cultivars of high yielding soft white
winter wheat (Triticum aestivum L. em Thell), Anza/Sturdy, Hill-
81, Stephens, and Yamhill, which differ in morphology, maturity,
and yield, to see if differences in production and distribution
of...
The reactions between sodium nitrite and the polyamines
spermidine and spermine were investigated. When reacted at 80°C
for 1 hr at pH 3.5 with a 1:3 molar ratio of amine groups to sodium
nitrite, five volatile nitrosamines were identified as products in the
nitrosation of spermidine. 3HC1, and two volatile...
The reaction of several primary amines with nitrite was investigated
with regard to the formation of N-nitrosamines. When reacted
in a low moisture system at 160°C with a 1:2 molar ratio of amine to
sodium nitrite, various primary amine hydrochloride salts were found
to give rise to heterocyclic nitrosamines. The...
The objective of this research was to clarify the basis
of subfertility in Delaware roosters. It was anticipated
that a sensitive method would be needed to compare seminal
plasma protein composition between subfertile and fertile
roosters. Consequently, the applicability of two-dimensional
electrophoresis was tested as a tool for the
analysis...
