Structure-property relationships in ferroelectrics extend over several length scales from the individual unit cell to the macroscopic device, and with dynamics spanning a broad temporal domain. Characterizing the multi-scale structural origin of electric field-induced polarization reversal and strain in ferroelectrics is an ongoing challenge that so far has obscured its...
A study was conducted using data collected from a sample of mint and
vegetable farmers in the Willamette Valley of Oregon. The study identifies the
influence of demographic differences, economic factors and irrigator attitudes on
irrigation efficiency.
Only two of the 19 characteristics theorized to influence irrigation

Lamprey eel harvesting has systematically and periodically occurred along the Siletz River and its tributaries for as many as hundreds, or thousands, or tens of thousands of years that human families and lamprey eel populations have coexisted in the Siletz Valley ecosystem. Historical, cultural, and biological information for the twentieth...
