The purpose of this study was to investigate the distribution
and magnitude of scattered radiation from a typical
mobile radiographic examination as an aid in evaluating
the potential health hazards of the scattered radiation.
Also discussed are current radiation protection standards and
recommendations for mobile radiography.

High-altitude color infrared photography is found to be
an effective tool for forest inventory in the Umpqua National Forest
of southwestern Oregon. Intelligent resource management requires
the rapid, accurate, and economical inventory results that can be
supplied by remote sensing. Color infrared film is shown to possess
properties that make...
Three distinct stages of flower cluster abscission were identified
prior to fertilization: flowers which did not begin development (stage
1), flowers which had begun development (stage II) and clusters which
had begun to form distinct nuts (stage III). Abscission of stages I
and II coincided with a rapid increase in...
A method for measuring the spark-shower radiance of metals
when abraded on an abrasive grinding wheel was developed for
evaluating their sparking tendency. One hundred metals were tested
and rated relative to commercially pure iron. The radiance was
measured in units of energy per solid angle per area of the...
The last two decades have seen many new continuum models for
electromagnetic materials which were constructed by merely adding
terms to the classical balance laws and constitutive equations. Nonlocal
theories, such as the one developed by A. C. Eringen., however,
depart from the traditional approaches by accounting for the effects...
Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
