Eastern Filbert Blight, caused by Anisogramma anomala (Peck) E. Miller, was first discovered in the Pacific Northwest in 1974. Orchard experiments suggest that the fungus completes its life cycle in two years. Infection takes place from mid-January to May, mainly through mite-galled-buds infested with an Eriophyid mite, Phytocoptella avellanae Nal....
This study focused on the development of a measure of the consumer
preferences of preschool children, the Consumer Preference Test
(CPT). A test-retest procedure was used to obtain a measure of reliability
for the CPT on a sample of 20 Caucasian, middleclass and
above children enrolled in the Child Development...
A classification of stationary liquids by infrared spectroscopy to evaluate the polarity was made using the solvent effect technique. The infrared C-Cl absorption frequency shift was measured for solutions of 1-chlorohexane dissolved in each stationary phase. These frequency shifts were correlated to the relative retention times of 1-octene/n-octane, trans-2-octene/n-octane and...
Eleven hand specimen whole rock (WR) samples (25-200 g each) and
33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture
Gorge, Oregon were analyzed via instrumental neutron activation
analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb,
Lu, Hf and Ta). Standard...
This was an experimental study designed to compare the effectiveness
of computer-assisted laboratory instruction to teacher-assisted
laboratory instruction based on student achievement in Elementary
Business Statistics. Computer-assisted laboratory materials and an
Elementary Business Statistics achievement test were evaluated.
Procedures
The setting of this experiment was at Southern Oregon State
College,...
The need for classifying vegetation in a more precise way is
evident. Also, there is a need to provide a hierarchical classification
scheme that will match changes in image characteristics as one
moves through the scales from space to conventional aerial photography.
Such refined classifications of vegetation are the first...
This paper presents a study of the resonant transfer of energy
between filters with the viewpoint of applying this technique to
communication systems.
A summary of the existing filter designs
for this application is made.
This summary shows that a requirement
common to all these filters is that the impulse...
