There is considerable uncertainty associated with stand
establishment in coastal Oregon. Several species can gain
control of the site depending on stand conditions as well as
management practices. In this study, three cover type
transition models were developed using data from the Siuslaw
National Forest to predict stand establishment patterns...
The specific geography of individual wine growing regions has long been understood to be a significant factor in predicting both a region’s success in producing high quality grapes, and the resulting demand for wines produced from that region's fruit. In the American wine industry, American Viticultural Areas (AVAs) are increasingly...
Neutron shadow holography is a method of obtaining a
three-dimensional neutron radiograph of an object using a
Fresnel zone plate as an encoding aperture. The object is
reconstructed by passing laser light through a miniature
copy of the radiograph. The technique has been applied
extensively with X-rays and gamma rays...
Herbicides were tested for the selective control of bentgrass in
Kentucky bluegrass turf under three levels of competition. Best control
in zero competition was obtained with a winter treatment of
bromacil at two pounds per acre. Under circumferential and direct
competition, best control was obtained with a summer and fall...
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 means of equations, yielding
different algebraic structures such as...
The presence of nitrates and nitrites in food is associated with an increased risk of gastrointestinal cancer and, in infants, methemoglobinemia. Nitrites are produced endogenously through the oxidation of nitric oxide and through a reduction of nitrate by commensal bacteria in the mouth and gastrointestinal tract. Despite the physiologic roles...
