We report optical modulation of continuous terahertz (THz)
wave in the frequency range of 570-600 GHz using photo-induced
reconfigurable patterns on a silicon wafer. The patterns were implemented
using programmable illumination from a...

The free convective heat transfer phenomena in air between two
vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the
other adiabatic.
A quartz fiber anomometer was...

Modern technology has advanced to such a high degree that
education now stands between all men and all work. What it means
in specific occupational possibilities and opportunities is the area
of this research. The farmer has made tremendous...

Soils developed on volcanic ash exhibit several unique properties
not commonly observed in soils formed on other geologic
material. Low thermal conductivities, low volumetric heat capacities,
slow transport phenomena, excess macro-drainage and...

The purpose of this investigation was to purify and characterize
the autolytic enzyme from cell walls of Bacillus subtilis 168. The
crude enzyme was obtained by autolysis of purified cell walls in
buffer at 37° C. Two purification methods were...

Long-term ecological data are crucial in helping ecologists understand ecosystem function and
environmental change. Nevertheless, these kinds of data sets are difficult to analyze because they are
usually large, multivariate, and spatiotemporal....

The objectives of this study were to evaluate and compare the
availability of native and applied P in Central Oregon pumice soils
with that in Willamette valley soils and calcareous soils from Eastern
Oregon. The experimental work to meet these...

The use of petroleum oil prevented, to varying degrees: the
transmission of three stylet-borne viruses in three different crops.
The use of oils resulted in a marked improvement in the number of
lily bulbs harvested from treated plots as compared...

In this paper, we are concerned with the very general notion of
a universal algebra. A universal algebra essentially consists of a set
A together with a possibly infinite set of finitary operations on. A.
Generally, these operations are related by...

The main goals of this study were: (1) to develop a combination
of soiling, laundering, and soil detection procedures which would be
accurate, reproducible, and relatively rapid; (2) to develop a quantitative
method to detect artificial soil on...

When the dc conductivities of various pure KC1 crystals were
compared it was found that crystals grown under an HC1 atmosphere,
from salt purified by ion exchange, exhibited lower knee temperatures
than any of the crystals studied. These knee...

This research was conducted to compare the performance of
community college students to four -year institutional students both
of which were enrolled in one of three different programs of general
college chemistry for nonscience majors during the...

Research was conducted to determine the distance and amount
of outcrossing between varieties of highly fluorescent annual ryegrass
(Lolium multiflorum Lam.) and low-fluorescing perennial
ryegrass (Lolium perenne L.). Studies were conducted under...

The behavior of individuals in decision making under risk was
investigated using choice structures of greater complexity than the
types examined in previous studies. The experiment performed consisted
of two phases. In Phase I a basic utility...

The 2011 M[subscript W] = 9.0 Tohoku-oki earthquake generated a large number of
unique soil liquefaction case histories, including cases with strong ground motion
recordings on liquefiable or potentially liquefiable soils. We have compiled a list...

Litter nutrient dynamics contribute significantly
to biogeochemical cycling in forest ecosystems. We
examined how site environment and initial substrate quality
influence decomposition and nitrogen (N) dynamics of
multiple litter types. A 2.5-year...

The effect of Endothal (3, 6-endoxyhexahydrophthalic acid),
sodium pentachlorophenate (Na-PCP) and TD-47 (di-N, N-dimethylcocoamine
salt of Endothal) on the microbial populations, ammonification,
nitrification and respiration in six different...

Flat, laminar, premixed hydrocarbon-air flames were stabilized
on a porous-plate burner. In addition to temperature profiles,
concentration profiles were measured for methane, ethane, ethylene,
propane, acetylene, propylene, carbon monoxide,...

A disease of sweet cherry (Prunus avium L.) known as "cherry
rosette" has threatened production of cherries in Oregon. In 1961
this disease was observed in widely separated orchards. Rosette
occurred in isolated trees or in spreading patterns,...

Verticillium dahliae Kleb. incites a vascular wilt disease of
mints. Susceptible Mentha piperita L. , resistant M. crispa L.,
and intermediate hybrid 148 were used to study 1) the site of differential
resistance and 2) the role of...
