The authors’ affiliation at the time of conducting the research should be given, more than two affiliations per author is not allowed. If an author has no institutional affiliation, state the city/state and the country of residence. The names of authors should appear in the order of their contributions. For names with suffixes (e,g., Jr. and II), separate the suffix from the rest of the name with a space instead of a comma.
