The Editorial Board found that substantial portions of the text came from other published paper. Comparing with the paper published in International Journal of Engineering, Science and Technology Vol. 3, No. 4, 2011, pp. 82-88 (www.ijest-ng.com), these two papers have the same contents before Figure 7 and the author added Fig. 8, 9, 10 on the 2012 paper. The scientific community takes a very strong view on this matter, and the Journal of Minerals and Materials Characterization and Engineering (JMMCE) treats all unethical behavior seriously. This paper published in Vol.11 No.5, 529-541, 2012 has been removed from this site.展开更多
