The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change
during the Neogene. Two north south transects were drilled (95° and 110°W) within the region of equatorial divergence driven
upwelling (and thus high accumulation rates and resolution) and spanning the major...
To facilitate the selection of drill sites for Leg 138, a site survey
program was conducted on board the Scripps Institution of
Oceanography's research vessel Thomas Washington (Cruise Venture
1). During this cruise, which departed San Diego on 30 August 1989
and arrived in Manzanillo, Mexico, on 4 October 1989,...
Climate change will continue to profoundly affect water supply and aquatic ecosystems in the Pacific Northwest. Changes such as warmer air temperatures, increases in the proportion of winter rain versus snow, reduced spring snowpack, and earlier snowmelt all affect streamflow. The response to these climate impacts includes earlier runoff peaks,...
Multiple use of waste heat from power plants may become an
important consideration in the development, siting, and certification
of these plants. A multiple use system of components that can
beneficially utilize waste heat may include home heating and cooling,
greenhouses, animal enclosures, open basins for single cell protein
production...
study investigated the validity of the Perceiving Emotions branch of the Mayer-Salovey-
Caruso Emotional Intelligence Test (MSCEIT). This was conducted through a correlational analysis with
three previously validated measures of nonverbal communication proficiency; The Profile of Nonverbal
Communication (PONS), the Diagnostic Analysis of Nonverbal Accuracy-2 (DANVA2), and the Affective
Communication...
Science inquiry is central to the science education reform efforts that began in the early 1990's. It is both a topic of instruction and a process to be experienced. Student engagement in the process of scientific inquiry was the focus of this study. The process of scientific inquiry can be...
High resolution, continuous records of GRAPE wet bulk density (a carbonate proxy) from Ocean Drilling Program Leg 138
provide one the opportunity for a detailed study of eastern equatorial Pacific Ocean carbonate sedimentation during the last 6 m.y.
The transect of sites drilled spans both latitude and longitude in the...
Establishing true depths of recovered sediments is critical to determining sedimentation rates for high-resolution paleoclimatic
studies. We have corrected the composite depth scale, which accounts for the entire continuous sedimentary sequence, so that sediment
depths are consistent with logging depths, or "true" depths. We accomplished this by taking advantage of...
Petroleum mulch applied on the soil surface over a row of
planted seeds promotes a more rapid and a more uniform germination
of seeds, enhances elongation of seedlings and in some cases increases
the yield of the crop. The beneficial effects of petroleum
mulch have usually been attributed to increased...
High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...
Cheatgrass (Bromus tectorum L.) is a widespread exotic weed in the Intermountain sagebrush steppe. An annual grass, it is highly prolific and very competitive with native perennial grass seedlings. A clipping experiment carried out at two cheatgrass-dominated sites (Lincoln Bench and Succor Creek) in eastern Oregon analyzed effects of defoliation...
Spring chinook salmon, Oncorhynchus tshawytscha, in the Snake River Basin are listed as endangered under the Endangered Species Act. The typical life history of spring chinook salmon is semelparous. An experiment was performed to see if mature male spring chinook salmon parr could be reconditioned after hand-spawning and spawned in...
Purpose: The purposes of this study are to determine the within subject and between subject effects of play markings, gross motor toys, and a larger play space on the physical activity of children with and without disabilities. Method: A group comparison design was implemented and a total of 12 children...
A continuous, low-velocity, nearly monochromatic atomic beam is created using
laser cooling and two-dimensional magneto-optic trapping. Rubidium atoms from an
effusive oven are slowed and cooled using Zeeman-tuned slowing. The scattering force
from a counter-propagating, frequency-stabilized diode laser beam is used to decelerate
the thermal beam of atoms to a...
Real transportation fuels contain a wide range of hydrocarbon species, and this complexity poses challenges for modeling. Surrogates with a simpler blend of hydrocarbon reference fuels can approximate the physical and chemical characteristics of real fuels and enable practical simulation of the reacting flows that occur in engines and combustors....
The purpose of this study was to understand the experiences of single fathers attending a community college. Single fathers comprise one-fifth of all single parent families, yet little research has been done on this growing segment of the population. A phenomenological approach was utilized to examine the attributes, needs, and...
An attempt is made to identify any significant
impact of the Salem urban growth boundary implementation on
rural residential development and land value outside of the
boundary. Studies done in 1972 examine possible boundary
impacts, but definite conclusions were not made because
county rural development policy had not been finalized....
