Abstract
The abstract is typically a mandatory item and the most read part of the paper. The abstract should be informative, not descriptive, and should be free of abbreviations except for units of measure. For some journals, the abstract should be a separate file to the manuscript. Many journals will ask you to supply the abstract as text as part of the submission procedure. In this case, the abstract should also be present as part of the manuscript.
