Polychlorinated dibenzo-p-dioxins (PCDD's) and
dibenzofurans (PCDF's) are environmental pollutants associated with the production and use of a number of industrial
chemicals. In addition, PCDD's and PCDF's are produced
during low temperature combustion of wastes containing
polyvinylchloride (PVC), chlorophenols, and a number of
other chemical precursors.
A significant source of environmental...
Heat and water vapor flow in summer-fallowed fields in the
Pacific Northwest may significantly affect the position and supply of
water for germination of fall sown crops. New tillage tools and
drill openers used in reduced tillage systems leave a trashy, residue covered surface in contrast to the traditional bare...
Two prevalent models of parallel programming are data parallelism and task parallelism. Data parallelism is the simultaneous application of a single operation to a data set. This model fits best with regular computations. Task parallelism is the simultaneous application of possibly different operations to possibly different data sets. This fits...
