The individual through earliest recorded history reveals contradictory views of the
human life-span. "Am I a free and unique individual, able to make choices and decide my
own destiny?, or, "Am I only a victim of circumstance, a speck of dust in the universe's
whirlwind of fate?"
Each view is...

The purposes of this study were to (a) provide insight into the use of item response theory (IRT) with psychomotor skills, (b) assess the psychometric properties of the Test of Gross Motor Development (TGMD) using IRT, and (c) provide a basis for future studies of the TGMD using IRT. The...
Three studies were designed to evaluate the promoting
effect of cyclopropenoid fatty acids (CPFA) on avian myeloblastosis
virus (AMV) infection in White Leghorn chickens.
In the first study effects on growth parameters, blood serum
and erythrocyte lipid composition of White Leghorn chickens
were investigated at 100 ppm and 300 ppm...
This study investigated the effect of cooking on the
neutral detergent fiber (NDF) content of cauliflower and
carrots. For each replication the vegetable was divided
in half to serve as its own control. One half was used
raw and the other half was cooked in 60 ml of distilled
water...
The filbert is propagated by layerage and a faster method is
needed to keep pace with the rapidly expanding industry and the demand
for new cultivars. Propagation by seedage and graftage were the
two methods selected for evaluation in the research. Seed experiments
were initiated to identify optimum treatments for...
New K-Ar age determinations on
basalts, basaltic andesites, and ash flow
tuffs from the central Western Cascades in
Oregon range in age from 32 to 3 Ma. The
ages decrease from west to east and with
increasing elevation. Volcanism has been
continuous throughout the evolution of the
Western Cascades, with...
The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2-
heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2-
one were synthesized and decomposed under a variety of
reaction conditions: dry lithium and sodium salt pyrolyses,
sodium methoxide thermolyses in diglyme and photolyses of
the lithium salt in tetrahydrofuran. The saturated analogues
2-heptanone tosylhydrazone and its 4,4-dimethyl
isomer afforded the...
