At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...
The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...
The nursing profession has long sought more diversity in registered nurses (RNs) to reflect the populations served. One way to enhance RN diversity is through diversity in community college (CC) associate degree in nursing (ADN) programs.
Since ADN programs lead to professional employment with middle-class wages, they form an important...
The use of radioactive isotopes as tracers in biological systems
has become widespread since the close of World War II. Proper
use of radiotracers requires a fundamental understanding of the physical
nature of radioactivity, the characteristics of ionizing radiation,
and the various methods available for measuring radioactivity.
More importantly, the...
Field, growth chamber, and greenhouse studies were carried
out to evaluate factors that cause low seed set in Dactylis Glomerata
L. The variety, 'Latar', and the parental clones of the variety,
'Pennlate', were studied in detail.
Floral anatomy investigations indicated that 98 percent of
Dactylis flowers opened at Corvallis in...
Differential equations governing the combined heat and mass
transfer in soils are developed. Transient heat, liquid and vapor
transfer with phase change is considered. The liquid transfer is
treated as a function of the hydraulic conductivity and the gradient of
suction potential. The suction potential is considered a function of...
Sea level and current observations made over the Oregon
continental shelf exhibit wavelike characteristics in a frequency band
from approximately 0.15 to 0.45 cpd. In a narrow band around
0.22 cpd the current-sea level relationship is consistent with the
predicted values for the first mode of Robinson's continental shelf
waves....
Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...
L-pipecolic acid (L-PA) is the higher homolog of proline. It occurs naturally in
many organisms, including primates, as an intermediate in lysine degradation. The
pathway by which lysine is converted into L-pipecolic acid employs the enzyme Lpipecolate
oxidase (L-PO), and appears to be tissue specific to the central nervous system...
Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...
