The distribution of adult Pacific herring (Clupea harengue
pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by
depth and geographic area over 24 successive months during 1973-75.
From June through September, schools concentrated at 5- to 37-m
depths where zooplankton was abundant, and moderate currents were
present in a...
Radiation therapy is a sophisticated complex process. Systematic methods are needed to quantitatively evaluate the quality of a complex process and hence radiation therapy treatments. An ideal result for a complex process must be established to determine if the complex process is completed acceptably. For radiation therapy, this can be...
Purpose
The purpose of this study was to discover the status and characteristics of reading programs in the public secondary schools of Oregon.
Procedures
Questionnaires were mailed to all of Oregon's 327 schools, 106

Investigations with ram semen were conducted to develop procedures
of cyrogenic preservation that would provide long-term
retention of fertilizing capacity in ram spermatozoa.
An isotonic extender consisting of egg yolk, sodium citrate,
lactose, glycerol, and a broad spectrum antibiotic was selected from
among several extenders tested in pilot studies. Using...
This investigation was undertaken to determine 1) the effects
of various carbon sources in defined media on pectolytic enzyme production,
2) the effect of the incubation period on pectolytic enzyme
activity, and 3) the development of improved methods for the purification
and characterization of the polygalacturonases (PG) produced
by Fusarium...
