*Unofficial 2015 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 Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2013 and 2014, and ‘B’ is the number of times these articles were cited in indexed publications during 2015 than, impact factor = A/B.
