Irrigated Acreage in Georgia's Altamaha River Basin During the Drought Year 2000 [PDF]
, 2005 Using a "mixed media" approach, which tracts changes in pixel (color) values over the summer indicating changes from dry land to wet land, we have developed estimates for irrigated acreage in the Altamaha River Basin that draws water from ground water or

Advanced Engineering Materials, EarlyView.This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

Advanced Engineering Materials, EarlyView.This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...
