They should have lines, letters, numbers and symbols of uniform strength and contrast. Fonts used inside Figures for lettering should not exceed 12 to 14 points. They should be pasted on the text at the appropriate places, as near as possible to their citations, centered between the margins. Figure and Table citations in the text will be made without using abbreviations . Authors who have access to italic and boldface should use these to identify physical or mathematical variables.
Variables are to be set in normal italic, vectors in boldface.
Physical constants like the Boltzmann constant are also set in normal italic. However, in conformity with the rest of the text, italics should be used if the sub- or superscripts are variables themselves. All references to publications made in the text should be set in a list of references following the text, and presented by placing increasing numbers in brackets. Do not type author and editor names in capitals. J.C.C. Abeliar and E. Betenck, J. Phys.
