Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...
We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...
The development of whey beverages including whey wine has been
an area of whey utilization research. One study to produce a commercially
salable wine from sweet whey, particularly cheddar whey, was
undertaken. It included developing a process to clarify the naturally
cloudy wine, monitoring the physical and chemical changes which...
Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...
A method has been devised for the digital recording of mass
spectra and for reduction of the data by means of the CDC-3300 digital
computer. The computer program *MASSPEC was developed to reduce
the digital data obtained from a rare-gas mass spectrometer.
The author devised a method of determining peak...
This report describes the hydrodynamic testing and
evaluation of a one-tenth scale model of the FMC Wave
Attenuation Device. The purpose of the test was to quantify
the wave attenuation characteristics and structural loading
induced by a test program of monochromatic incident waves
on the submerged structure. The device was...
This report presents data collected on six cruises made during the months May-October 1972 along the Oregon coast. Both complete data listings and sequential surface data contour charts are presented. The latter graphically display rapid changes in surface water characteristics on time scales as short as a few hours.
The...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
This book is an environmental primer for the people of the Willamette Valley. It sets forth basic principles showing how men's actions cause future consequences in the environment.
Setaria lutescens (yellow foxtail) plants, grown from five seed
sources were compared in California. Seed sources were: Connecticut,
Iowa, Massachusetts, Pennsylvania and California. Morphological
and physiological differences between biotypes include: plant
size, growth habit, time required to mature and reproductive capa
city. Most significant is the prostrate habit of the...
Twenty-five idiopathic developmentally delayed children between
two and ten years old were studied. A group of thirty non-delayed
children of like age and sex was used as a control. Dietary
information was collected for each subject via a 24-hour dietary
recall, a two-day diet record, and a food frequency crosscheck....
This report is a critique of a study by the U.S. Environmental Protection Agency that found a statistically significant correlation between the application of the herbicide 2,4,5-T (dioxin) and miscarriages in the Alsea watershed. "If there is a relationship between herbicide use and miscarriages in the 'Alsea Basin' and its...
Both Leperisinus oregonus and L. californicus are bark beetle
species which emerge from Fraxinus latifolia brood logs as sexually
immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L.
oregonus enter trunks and branches, whereas L.; californicus enter twig
crotches, buds and...
This report represents the progress in "Ecological and Radioecological
Studies in the Columbia River Estuary and Adjacent Pacific
Ocean" for the period 1 April 1975 through 31 March 1976. This research
has been supported with funds from the Division of Biomedical and
Environmental Research, U.S. Energy Research and Development Administration...
Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...
This report presents progress accomplished during the 20-month period from 1 July 1972 through 31 March 1974 as part of the program "Ecological Studies of Radioactivity in the Columbia River Estuary and Adjacent Pacific Ocean". This program is a continuing study supported by the Division of Biomedical and Environmental Research...
Salinity, temperature, oxygen, phosphate, and nitrate observations were taken by Oregon State University on 16 hydrographic cruises in the Northeastern Pacific Ocean during 1969. Alkalinity , pH and silicate were taken on special occasions. Nine cruises were taken along the Newport line. The rest were special cruises made off Depoe...
