Citation of references in the text should be placed within parentheses, with the author’s last name and year of publication. E.g (Otaze, 1975) or (Esan and Vrbka, 1997). For more than two authors write, for example (Bala et al 1997). Differentiate among citation of authors that have more than one article in the same year by the letters a, b or c following the year. If the author’s name is part of the sentence place only the year in parenthesis. Table – Number tables according to their sequence in the text.

Units: Standard International (SI, or metric) units must be used. Defined all special symbols, non standard units, acronyms, and abbreviations when first used in abstract and again in the main body of the text. Use them consistently thereafter. Mathematical and physical symbols of units such as%, “ C should be preceded by a space (60 %, 18 C).

Figures Captions: Number figures according to their sequence in the text. Each figure must be captioned after the figure number, below the figure. Where figures cannot be submitted electronically the originals or sharply focused photographic prints (reduced to size the figure space provided in the text) must be submitted within the manuscript.

Reference: At the end of the text, list references alphabetically by senior author. Include only those references
that are cited in the text and use hanging indent format .Abbreviate journal and organization names
