Phase distribution parameter determination by neutron radiography

Creator:

Skinner, Jesse B.

Abstract:

A phase distribution parameter has been added to the one-dimensional two-phase horizontal flow conservation equations. The phase distribution parameter was incorporated into the conservation equations in an attempt to add stability and remove correlation switching by incorporating gravity. Determination of the phase distribution parameter requires an average void fraction profile...

Influence of cover crops on vine performance at two Willamette Valley vineyards

Creator:

Sweet, Rebecca Marie

Abstract:

It is estimated that 50-75% of Oregon vineyards cultivate at least every other alley in order to 1) reduce water stress 2) increase vineyard canopy temperatures and 3) increase nutrient availability. Because many vineyards are situated on steep hillsides, frequent tillage could result in increased soil erosion, decreased soil quality...
