Soil solution samplers have certain inadequacies that limit their range of
possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the
soil pore-water via a fiber glass wick, have shown promising results in preliminary
experiments in regard to collection efficiency of water and of bromide tracers. The
objectives of...
Assessment of the environmental impacts of an agricultural production system
requires information on both soil water quality and solute flux. Passive Capillary Samplers
(PCAPS), which sample water from the vadose zone using fiber glass wicks, have shown
potential to provide both flux and solute concentration in unsaturated zone sampling but...
The purpose of Oregon's Nearshore Research Inventory (NRI) project was to inventory and map the current and future use of Oregon's nearshore environment by the scientific research community for use in Oregon's marine spatial planning process. Spatial and qualitative data on the use of Oregon's ocean and coast by the...
The present thesis is about the electric power distribution system
for the city of Mecca, in Saudi Arabia. The distribution system
of Mecca started suddenly, grew haphazardly and developed quickly
with a load factor as high as 38%. Lack of planning, records and
training plus insufficient experience of management evolved...
Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...
Nitrogen deficiency during the winter where winter wheat
(Triticum aestivum L.) follows wheat and large amounts of straw
have been plowed down has been a factor limiting yield in the
Willamette Valley of western Oregon. Field experiments were
established to determine if an application of N on the stubble or...
A study was conducted to determine the effect of the milk ejection reflex on exogenous gonadotropin releasing hormone (GnRH)- induced release of luteinizing hormone (LH) after short term calf removal. Twenty-four postpartum multiparous beef cows were assigned 3 randomly to groups arranged in a 2[superscript 3] factorial design to be...
Workers with dimethyl sulfoxide (DMSO) in the
United States and England have reported in the literature
that the chemical affects the weight gaining ability of
experimental animals. Narula, University of Oregon
Medical School, Portland, found that 50 parts per million
DMSO increased the size and numbers of tissue culture
cells....
Fourteen multiparous Holstein cows were paired by stage of
lactation and previous years milk yield and 14 Holstein first-calf
heifers were paired by stage of lactation. One member of each pair
was assigned to a 24L:OD or a 18L:6D photoperiod for 16 wk during
winter 1981 (Experiment 1). A similar...
A comparative investigation of the phenotypic properties of environmental and clinical strains of the lactose-positive human pathogen, Vibrio vulnificus, revealed that they are indistinguishable in traits commonly used for identification in clinical and public health laboratories. It has also been confirmed that there are other strains of undefined Vibrio spp.,...
