The treatment of wastewater is an expensive and energy-extensive practice that not only ensures the power generation requirements to sustain current energy demands increasing human population but also aids in subsequent removal enormous quantities need be treated within environment. Thus, renewable source-based one recently developing techniques overcome environmental contamination issues. In t...

SUMMARY This is the second in a series of two papers in which the patch recovery technique proposed by Zienkiewicz and Zhu 1]-3] is analyzed. In the rst paper 4], we have shown that the recovered derivative by the least squares tting is superconvergent for the two point boundary value problems. In the present work, we consider the two dimensional case in which the tensor product elements are us...

Feasibility tests were initiated to determine if the zirconium in commercial used nuclear fuel (UNF) cladding can be recovered in sufficient purity to permit re-use, and if the recovery process can be operated economically. Initial tests are being performed with unirradiated, non-radioactive samples of various types of Zircaloy materials that are used in UNF cladding to develop the recovery pro...
