Accelerated destructive degradation tests (ADDTs) are widely used in manufacturing industries to obtain timely product reliability information, especially in applications where few or no failures are expected under use conditions in tests of practical length. An ADDT plan specifies the test conditions of accelerating variables, running time, and the corresponding allocation of test units to eac...
The increasing popularity of urban agriculture as a method of localizing food systems has created a mounting need to address soil pollution in urban farms. Lead is an especially pervasive pollutant in urban soils with a number of detrimental health effects. Phytoremediation, the use of plants to extract or degrade pollutants, has shown promise for cleaning up leadcontaminated soils, yet its pot...
