Optimizing Soil Moisture Uniformity and Irrigation Management
This research is a study on the relationship of irrigation water treatments and soil moisture distribution uniformity (DU). Soil moisture distribution was based on long-term data sets that were collected during wet and dry soil conditions (from permanent wilting point to field capacity) using a novel electromagnetic sensor-based platform moving inside subsurface horizontal access-tubes. The irr...

the peak temperature in the sample was directly measured while the laser power was slowly increased. As soon as melting occurred in the hottest portion of the sample, the absorption increased drastically, leading to "runaway" melting and subsequent melting phenomena [figure 2B of (1)]. The melting temperatures we reported are the last temperatures of the solid before melting set in. We stated (...

متن کاملOn Uniformity Within
1 Abstract In order to study circuit complexity classes within NC 1 in a uniform setting, we need a uniformity condition which is more restrictive than those in common use. Two such conditions, stricter than NC 1 uniformity Ru81,Co85], have appeared in recent research: Immerman's families of circuits deened by rst-order formulas Im87a,Im87b] and a uniformity corresponding to Buss' deterministic...
متن کاملSoil mineral structural water loss during loss on ignition analyses
Sun, H., Nelson, M., Chen, F. and Husch, J. 2009. Soil mineral structural water loss during loss on ignition analyses. Can. J. Soil Sci. 89: 603 610. Water loss from soil minerals has been known to cause errors in the determination of soil organic matter when the loss on ignition (LOI) method is used. Unfortunately, no known published studies reliably quantify the range of structural water in t...
