Concerns were raised regarding Figure 13C. It appears that parts of Figure 13C overlap with Figure 13B. As a result of the University's inquiry into this matter, it was determined that the research in question underlying the publication was not undertaken within Ryerson labs and a copy of the data was not retained by the authors. As the authors were not able to produce a copy of the underlying data for independent verification, they have agreed to retract the article. Mustafa Abu Ghalia, Ibrahim Inuwa, Azman Hassan, and Yaser Dahman agree to this retraction.
