References: In the text, a reference identified by means of an author‘s name should be followed by the date of the reference in parentheses. When there are more than two authors, only the first author‘s name should be mentioned, followed by ’et al‘. In the event that an author cited has had two or more works published during the same year, the reference, both in the text and in the reference list, should be identified by a lower case letter like ’a‘ and ’b‘ after the date to distinguish the works.

Examples in Text

Clifford (1978), Fernandez et al. (1971), (Griggs, 1990), (Parks and Harry, 1982), (Henderson, 1981; Mohammed, 1999 a, b; Anna, 1988, 1975), (Sires et al., 1967)

References should be listed at the end of the paper in alphabetical order. Articles in preparation or articles submitted for publication, unpublished observations, personal communications, should not be included in the reference list but should only be mentioned in the manuscript (e.g., K. Gibson, University of Washington, U.S.A). Journal names are abbreviated according to Chemical Abstracts. Authors are fully responsible for the accurate citing of the references.
