BACKGROUND/PURPOSE: Exposure from medical radiation sources are on the rise in the United States. Often the highest potential source of radiation dose to patients and radiology staff occur during interventional radiology procedures performed using fluoroscopy and digital subtraction angiography (DSA) to provide image guidance in minimally invasive surgical procedures. Several...
Paleomagnetic directions from the Eocene Tillamook Volcanic Series of the Oregon Coast Range
point 460 clockwise from the expected Eocene field direction. Potassium argon dating of six dikes and
flows from this formation yields a mean age of 44.3 ± 0.6 m.y. These results establish that the Oregon
coastal block...
The disposal of radioactive waste products is a serious problem facing scientists and the public. One solution proposed is to dump these waste products at sea, with the area of northern Oregon and southern Washington in 100 to 1,000 fathoms as one area of consideration. However, one of the problems...
The purpose of this research was to investigate the
effects of three levels of contextual interference on the
acquisition and retention of a sequential motor skill, by
moderately mentally retarded and nonretarded subjects. The
subjects were functioning between an eight and twelve year
level. The dependent measures included; Reaction Time...
The purpose of the study was to analyze the effect
of experimenter delivered and microcomputer delivered
knowledge of results on the response speed of nonretarded
and mentally retarded public school students. Response
speed was measured for 63 nonretarded students and 63
mentally retarded students. Subjects were randomly
assigned to conditions...
Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available...
