The paleomagnetic history of the volcanic rocks of Easter
Island was investigated using standard paleomagnetic techniques.
The remanent magnetization of 673 specimens from the three volcanic
episodes recognized on the island were measured using a spinner
magnetometer. Inclinations, declinations and virtual geomagnetic
poles were calculated for each flow. The majority...
Limnology is undergoing a transition to high-throughput -omic analysis of freshwater
bacterial communities. An important first step in making the transition is to
characterize several genomes that can be used as references to guide metagenome
assembly and analysis. Here I characterize four new freshwater cyanobacterial
genomes, a pair of lake...
Modern agricultural erosion was studied using ¹³⁷Cs from
fallout as an indicator of erosion/deposition. The study area was a
285 ha agricultural watershed in the hilly western margin of the
Willamette Valley, a high winter rainfall zone in which fall-planted
crops are commonly grown.
Objectives of the study were (i)...
Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo
blight of Phaseolus vulgaris L., have been examined for
the presence of circular duplex deoxyribonucleic acid
(DNA)....
The purpose of this research was to explore the perceptions of employers, teachers and graduates of the Oregon Carl Perkins Single Parent/Displaced Homemaker Programs regarding non-technical employment qualities. The Luft "Non-Technical Employment Qualities Survey Instrument" and open-ended questions were used to elicit personal responses from members of each group for...
The main purpose of this study was to examine the influence of
additional content from areas of mainstreaming and adapted physical
education on preservice elementary educators attitudes toward
teaching nonhandicapped and handicapped children in elementary
physical education. To achieve this goal (a) an instrument was
constructed to assess the attitudes...
Cardiac A₁ adenosine receptors mediate cardioinhibitory
properties of adenosine and structural congeners. The objective of
these studies was to increase our understanding of molecular
processes involved in ligand interactions with receptors mediating
cardioinhibitory effects of adenosine and the interactions of these
receptors with guanine nucleotide binding regulatory proteins.
Porcine atrial...
A sophisticated computer program is developed to analyze flow linear
dichroism data on nucleic acids for individual base inclinations. Measured
absorption and linear dichroism data for synthetic AT and GC polymers and
natural DNAs are analyzed. The reliability of the program is tested on data for
the synthetic polymers, and...
