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
junior high schools and 221 senior high schools. Responses were received
from 84.7 percent of the...
This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...
Aerial photography has become a valuable method of acquiring
information on estuarine current circulation patterns. The method
provides a comprehensive picture of nearly simultaneous surface
water movements. It represents a significant improvement over
conventional surface float and current meter methods because large
areas may be covered in great detail with...
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...
Pelvetiopsis limitata (Setchell) Gardner (Phaeophyta,
Fucales), collected on the central Oregon coast, was
studied by electron microscopy, and by light microscopy
using methacrylate embedding and toluidine blue, acid fuchsin,
PAS and anilin blue staining. The sperm of both P.
limitata and Pelvetia fastigiata (J. Agardh) DeToni (from
northern California) are...
The g-factor of the 482 Key (Kiloelectron volt) state in Ta¹⁸¹
and the half-lives of the 25.6 Key and 74.5 Key states in Dy¹⁶¹ have
been measured by the delayed coincidence method. The g-factor of
the 482 Key state in Ta¹⁸¹ was determined by observing the effects
of an external...
