The conventional method for determining lumber strength depends
on visual evaluation by lumber graders which often results in
undergrading of lumber. Nondestructive proof testing is used less
often and provides for only estimates of elastic moduli of elasticity
and rupture. The evaluation of nondestructive variables such as
proportional limit (PL)...
The growing use of light-frame wood trusses in the
residential and commercial construction has generated the
need for general analysis procedures for predicting
deformations and ultimate load of truss-plate joints, which
are the basis for accurate evaluation of structural
performance and design of complete truss assemblies. This
dissertation was aimed...
One reading of the post-postmodern literary period argues that as formal aesthetics have (re)engaged with ethics there has been a concomitant move to treat literature as a space of ethical potential. Adam Kelly has called this attitude, when combined with the appropriation of certain metafictional and postmodern techniques, the “New...
L. C. Dunn (1893-1974) spent most of his scientific career conducting research in
developmental genetics as a member of the Zoology Department at Columbia
University in the City of New York. He had an accomplished scientific career
researching mutations in mice, which earned him respect from other geneticists and
scientists....
This research proposes a Human Fallibility Identification and Remediation Methodology (HFIRM) that supports the systematic identification and remediation of potential human errors. The objective of this research was to develop and test a prototype framework that supports the practical application of human factors knowledge to the analysis and design of...
Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales. Eighty-two
percent of the hatchery and 89% of the wild fish were correctly...
Hydrogen cyanamide (CY) has been used to break rest
in temperate crops, but levels used to overcome rest are
sometimes toxic to plants. The rest breaking effect of CY
is thought to involve peroxide metabolism. Inhibition of
catalase by CY has been proposed as a mechanism for
overcoming dormancy in...
Every year thousands of families experience a major
life-changing event when they are torn from their
homeland and become refugees. Little is known about how
the refugee experience impacts the family and how members
perceive it affects their sense of family identity. The
construct of family identity as proposed by...
A rapid and sensitive HPLC method for quantifying both the
reduced and oxidized forms of glutathione simultaneously in woody
plant tissues was developed. This method was applicable to a variety
of woody plant species and different tissues. Total glutathione
content in the bark tissue of seven of the woody plant...
