Four decades after the passage of the US Clean Air Act, air-quality standards are set to protect ecosystems from damage caused by gas-phase nitrogen (N) and sulfur (S) compounds, but not from the deposition of these air pollutants to land and water. Here, we synthesize recent scientific literature on the...
Nonlinear optical processes can be described as multiphoton scattering events in terms of high order perturbation theory. The standard procedure for quantitative calculation of high order terms is to impose a steady state condition on the perturbative radiation fields. In the present work, this condition will be lifted, and explicit...

AN ABSTRACT OF THE THESIS OF
RobinL. Zagone for the degree of
Nonlinear optical processes can be described as multiphoton scattering events in terms of high order perturbation theory. The standard procedure for quantitative calculation of high order terms is to impose a steady state condition on the perturbative radiation fields. In the present work, this condition will be lifted, and explicit...
Potash rate and source effects on tuber yield and quality
(hollow heart, size, and processing quality), and nutrient (K, Ca,
Mg, and C1) concentrations in petioles and tubers were evaluated in
three experiments, two in the Columbia Basin in Oregon (McDevitt and
Levy) and one in Central Oregon (Powell Butte)....
Effect of a sudangrass green manure in two soil types on the activity, populations
and community structure of soil microorganisms, populations of Verticillium dahliae in
soil and on potato roots, and potato early dying, were evaluated in a field microplot
experiment in the Columbia Basin. Potato cv. Russet Burbank was...
Effects of amount of applied water and frequency of irrigation
on head rot and yield of three broccoli cultivars were evaluated in
1987 and 1988. Two irrigation frequencies were established with a
line-source sprinkler system for 5.5 weeks during heading. The low-frequency
experiment was watered once per week and the...
