A multielement spectrometer has been developed for the simultaneous determination of four elements by atomic absorption (AA) or atomic fluorescence (AF). The spectrometer is based on a multiple exit slit monochromator and uses a mirrored funnel to direct light from the various exit slits to a single photomultiplier. There are...
C-methyltransferase
(HIOMT) in chinook salmon (Oncorhynchus
tshawytscha). Various body tissues, as well as several
morphological brain divisions were tested for the presence
of HIOMT. Activity was found in the retina, the dorsal
portion of the diencephalon, and in the pineal gland of
chinook. However, the activity was significantly higher
in...
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 research presented in this thesis was designed to evaluate
the effects of feeding alfalfa hays from the Klamath Basin of Oregon
in practical dairy rations on milk fat production in high-producing
Holstein cows. Thirty-two second lactation or older animals estimated
to be capable of producing at least 70 lbs...
This study was undertaken to find means of separating the
morphologically similar species of North American Trixagus and to
bring together information on Trixagus and Pactopus.
A key to separate the world's eight genera of extant Throscidae
is presented for the first time. A key to the five species of...
Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...
The WSR-57 weather radar operated by the National
Weather Service at Sacramento, California, plus a network
of precipitation gages provided data for this comparison
of radar reflectivity with precipitation rates. Located
in a valley with mountains within range of the radar on
three sides, this radar has varying sensitivity for...
This study deals with intergenerational differences in the
industrial environment. Rapid changes in our social and technological
society suggest the characteristics of dogmatism and trust as possible
indicators of differences between practicing professionals and upper
division university students.
Each subject's reaction to change was measured through administration
of Rokeach's Dogmatism...
The study is designed to determine what differences exist between
the nonverbal as well as verbal behaviors and teacher-student
interaction patterns in selected CHEM Study and traditional chemistry
classes in Oregon. Analysis of behavior in these classes is in terms
of a new observation system developed by H. D. Schalock...
