Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp ‘‘tropopause.’’ In the tropics, this layer is often called the ‘‘tropical tropopause layer’’ (TTL). We present an overview of observations in the TTL and discuss...
Observations of CO2 were made in the upper troposphere and lower stratosphere in the deep tropics in order to determine the patterns of large-scale vertical transport and age of air in the Tropical Tropopause Layer (TTL). Flights aboard the NASA WB-57F aircraft over Central America and adjacent ocean areas took...
During the Tropical Composition, Clouds and Climate Coupling (TC4) experiment
that occurred in July and August of 2007, extensive sampling of active convection in the
ITCZ region near Central America was performed from multiple aircraft and satellite
sensors. As part of a sampling strategy designed to study cloud processes, the...
Contrasted to the rich body of literature on ill children in
medical settings, well children's reactions to routine health care has
drawn little attention. This study assessed healthy children's under
standing of their bodies, medical procedures, and how this knowledge
relates to their behavior during routine health care. The study...
The purpose of this study was to determine the
effect of immediate prior meditation (transcendental
meditation) and relaxation upon the pattern of physiological
response and performance of a fine motor and
gross motor task. A second purpose of this study was
to determine whether the long term regular practice of...
Cloud-resolving large-eddy simulations (LES) on a 500 km × 500 km periodic domain coupled to a thermodynamic ocean mixed layer are used to study the effect of large-scale moisture convergence M on the convective population and heat and moisture budgets of the tropical atmosphere, for several simulations with M representative...
The bioavailability of chemical compounds in the marine environment fundamentally influences the growth and physiology of microorganisms. Organic and inorganic chemicals that are produced by some marine plankton can be consumed by other plankton for energy production, growth, or to initiate essential physiological processes. Cultures of the diatom Thalassiosira pseudonana,...
The objectives of this study were to evaluate the effects of site
potential, season and plant part on percent crude protein, percent
digestibility of dry matter and yield of cereal residues. Three cereal
types, club wheat (Triticum aestivum) tall, bearded wheat (T.
aestivum), and barley Hordeum vulgare) were examined.
Stress...
This study was designed to determine whether or not students'
emotions and coping would change during stages of an examination.
If changes in emotions and coping were recorded at different phases of
an examination, then these findings would substantiate the position that
stress and coping are processes. In addition, the...
Field study with 5 tall fescue genotypes treated at the vegetative
growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide
was initiated in July, 1980. The regrowth of these plants were again
treated at the booting growth stage in April, 1981, with the same
rates of mefluidide as...
Previous research had indicated that siblings of deceased children
developed a variety of behavioral problems as a result of the
death (Binger et al., 1969; Cain et al., 1964; Martinson et al., 1980;
Stehbens, & Lascari, 1974). The purpose of this study was to determine
the relationship of selected factors...
Aerosols and clouds have important effects on Earth's climate through their effects on the radiation budget and the cycling of water between the atmosphere and Earth's surface. Limitations in our understanding of the global distribution and properties of aerosols and clouds are partly responsible for the current uncertainties in modeling...
The purpose of this study was to identify significant differences
in body composition, body cathexis, and attitudes toward obesity
of women in various age groups involved in different levels of physical
exercise.
A total of 216 women, ranging in age from 17 to 64, took part in
this study. They...
Decreases in glenohumeral (GH) rotation motion and rotator cuff strength have been linked to multiple pathologies in the throwing arms of baseball pitchers, but a full understanding of the shoulder mechanisms affected by a total arc of motion deficit (TAMD) has not yet been achieved. This study was designed to...
Five simulated precipitation patterns characteristic of the Columbia
Basin and Plateau region and six fertilization rates were evaluated
for their effect on percent crude protein, percent in vitro dry matter
digestibility, fiber content, and yield of wheat aftermath on a commercial
farm in north central Oregon.
The higher moisture regimes...
In this dissertation, the structure and electronic properties of multiple metal oxide thin films are characterized and presented. Prompt inorganic condensation (PIC) of metal-oxo and –hydroxo clusters was evaluated as a technique for making metal oxide clusters in two separate studies. The first focuses on the synthesis of lithium niobate...
The aim of this dissertation is to develop oxide semiconductors by radio-frequency
sputtering for thin-film transistor (TFT) applications. A variety of oxide semiconductors
are used as the TFT channel layer, including indium gallium oxide (IGO), zinc tin
oxide (ZTO), and indium gallium zinc oxide (IGZO). The variety of materials used...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...
