Font type and sizes
Only Times New Roman font is accepted in manuscript. Main headings (Introduction, Materials and Methods, Results and Discussion, Conclusions, Acknowledgments, References) are set in bold roman (12 points) type at the left of a column. Minor headings are set in bold roman (11 points). A regular 11 point size must be used throughout the context. Start a new paragraph by indenting it from the left margin by 7 mm (not by using multiple empty spaces)
