Evaporation of saline solutions from porous media, common in arid areas, involves complex interactions between mass transport, energy exchange and phase transitions. We quantified evaporation of saline solutions from heterogeneous sand columns under constant hydraulic boundary conditions to focus on effects of salt precipitation on evaporation dynamics. Mass loss measurements...
As drop-on-demand (DOD) applications continue to gain ground in desktop inkjet-printing, 3D printing, fluid mixing, and other areas the demand for higher frequency operations are beginning to push against the current physical boundaries in DOD technology. The current research is exploring the possibility of controlling drop volume and velocity at...
This dissertation explores the real world problem of rural youth out-migration and finds that the central problem is one of persistent class difference in this rural Oregon town. The research that informs this dissertation was conducted in a rural community of approximately 2300 residents in Eastern Oregon, here called Talltown....
