Upon submission of an article, authors are supposed to include all figures in the manuscript in .doc, .docx, TIFF or JPEG format. All figures should be referred to in the manuscript in a proper sequence (Figure 1, Figure 2). The legends should be included in the main manuscript text file at the end of the document, rather than being a part of the figure file. For each figure there should be legends and the figure also be discussed in the text of the manuscript.
