Directly below commercial mint fields, percolation in excess of 10 ppm of nitrogen as nitrate (NO3 --N), the EPA drinking water standard, occurs for much of the year (Figure 1, page 2). Concentrations rise rapidly after irrigation starts in June, indicating that this nitrogen is being pushed through by irrigation...
The wind speed and significant wave height (H1/3) dependencies of the sea state is in altimeter estimates of sea level, expressed in the form ∆hSSB=bH1/3, are examined from least squares analysis of 21 cycles of collinear TOPEX data. The bias coefficient b is found to increase in magnitude with increasing...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
The paper is a study of (i) the realization of the gyrator,
(ii) active filter synthesis using gyrator.
Several realization methods of the gyrator are summarized.
A practical gyrator composed of two operational amplifiers was built
and tested. The experimental results are shown. Two RC-gyrator
synthesis techniques are derived and...
Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences
for understanding the role and character of deep Pacific-mantle return flow. The relative motion between
these primary hot spots can be inferred by comparing the age records for their seamount trails. We report
⁴⁰Ar/³⁹Ar ages for...

Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...
Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
This text was written for the purpose of explaining the use of the engineer's transit, theodolite, engineer's level and plane table in the solution of fundamental problems related to Forest Engineering. While the use of the infrared and electronic distance measuring instruments do have a place in Forest Engineering, they...
