Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).
This article has been retracted at the request of the Editor-in-Chief.
The authors have plagiarized part of a paper that had already appeared in Water Research, 35 (2001) 1-22. http://dx.doi.org/10.1016/S0043-1354(00)00247-5 and Renewable and Sustainable Energy Reviews, 14(2010) 1187–1201. http://dx.doi.org/10.1016/j.rser.2009.11.014. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
