Contracting nucleolar vacuoles are a general and consistent
feature of somatic tobacco cells growing in microcultures. Nucleolar
vacuoles were studied in cells from callus tissues of two
single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana
tabacum X N. glutinosa). Vacuoles periodically contracted either
completely or incompletely, apparently releasing a...

Diets containing cyclopropenoid fatty acids (CPFA) were fed to
rainbow trout. At a level of 223 ppm (from Sterculia foetida oil),
these CPFA in six weeks reduced weight gain by as much as 50 percent
over the control fish on the same diet without CPFA. Compounds
containing the intact cyclopropene...
Rainbow trout were fed semi-purified diets containing cyclopropenoid
fatty acids, and the biological effects of these acids were
investigated. These fatty acids occur naturally in cottonseed oil and
have been implicated in a large number of physiological disorders.
Included in this study was an investigation of the pattern of deposition...
The purpose of the study was to determine the current status
of provisions being made to provide for appropriate utilization of
the increasing quantities of audiovisual equipment and materials
available in the public schools of Oregon. The ultimate objective of
the study was to identify activities and programs essential to...
