[9]” or “reference [9]” except at the beginning of a sentence: “Author1 and Author2 in [9] show(ed)...” or “Author1 et al in [9] show(ed)”.

Place tables as close as possible to the text they refer to and aligned center. A table is labeled Table and given a number (e.g., Table 4: Effect of temperature on pseudo-first-order rate constants (kobs/ky) and thermodynamic parameters for the reaction of Hg(II)–Gly-L-Ala complex with ninhydrin.) it should be numbered consecutively. The table label and caption or title appears 8pt space above the table, 10pt space after the text or paragraph if any; it should be uniforms fonts and font size, and use 10pt font size and Times New Roman style and aligned center. Sources and notes appear below the table, aligned left. All tables must be in portrait orientation.


All illustrations are called Figures and should be referred to as Figure at the start of the sentence. Figures should be numbered serially and should appear in text in order. Place figures as close as possible to the text they refer to and aligned center. Photos, graphs, charts or diagram should be labeled Figure (do not abbreviate) and appear 8pt space below the figure, 11pt space before the next text or paragraph, and assigned a number consecutively. The label and title should be in line with the figure number (e.g., Figure 1: Mapping nonlinear data to a higher dimensional feature space), it should be uniforms fonts and font size; use 10pt font size and Times New Roman style and aligned center. Source (if any) appear underneath, flush left. Figures should be at good enough quality.

Clear digital photographs (high resolution) are accepted in TIF or JPEG formats.    Field photographs must contain a scale.

Map keys should be given on map or figure, not as numbered boxes.
