*Unofficial 2015 Journal Impact Factor was established by dividing the number of articles published in 2013 and 2014 with the number of times they are cited in 2015 based on Google search and the Scholar Citation Index database. If 'X' is the total number of articles published in 2013 and 2014, and 'Y' is the number of times these articles were cited in indexed journals during 2015 then, journal impact factor = Y/X
