Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo
blight of Phaseolus vulgaris L., have been examined for
the presence of circular duplex deoxyribonucleic acid
(DNA)....
Progeny from three sires of differing genetic background were
divided within litters by sex and placed on either a 15 or 19% protein
ration. The test period began when the experimental animals weighed
60 pounds and continued until they were slaughtered at 225 pounds.
This test period was divided into...
An obstruction theory is developed for "simplicial
bundles" which are generalized fiber bundles (over a
simplicial complex). Cross sections of one of the examples
of a simplicial bundle given (the Lefschetz bundle) are
essentially fixed point free maps of the base space.
The diffuse irradiance of slopes relative to the diffuse irradiance of a horizontal surface is calculated by integrating the mean radiance distributions of cloudless skies in Britain for a wide range of solar elevations, azimuths and slope angles. There is reasonable agreement with measurements reported from a number of stations;...
ScholarsArchive@OSU (SA@OSU) has stood as Oregon State University’s institutional repository for nearly a decade, and has seen a great deal of success, by many metrics, as such. Over that time period, the mission, content types, and stakeholders of the repository have changed, as has the ecosystem of available and emerging...
The enhancement of monthly averaged evaporation by atmospheric mesoscale systems is estimated from long-term hourly observations of surface meteorological data from the Tropical Ocean Global Atmosphere (TOGA) Tropical Atmosphere Ocean (TAO) buoy moorings over the equatorial Pacific Ocean and a bulk aerodynamic flux algorithm developed as a result of the...
Fisheries models often assume that discarded undersized fish and target species will survive and contribute to future recruitment and yield. If smaller fish are more susceptible to capture stressors than larger fish, then the assumption that smaller discards would contribute to recruitment may not be true. We tested the hypothesis...
When a shade ring is used to shield a pyranometer from direct solar radiation, a correction to the
measured diffuse radiation is necessary to account for diffuse radiation intercepted by the ring. A general
analysis is developed to relate shade-ring corrections to the radiance distribution of diffuse radiation. The
corrections...
The angular distribution of diffuse radiation was measured from May 1976 to May 1977 with a set of
purpose-built actinometers. Radiance distributions for 98 overcast hours were fitted well by an expression
similar to the conventional function for a 'standard overcast sky' (SOC). However, values of the coefficient
b averaged...
