TYPES OF CONTRIBUTIONS

MANUSCRIPT PREPARATION

Manuscripts should be in double-spaced typing on A4 paper with a wide margin to the left hand side. The title page should contain the title, author(s) name(s) and affiliation(s), including a complete address for correspondence and proofs. Each manuscript should be provided with an abstract of not more than 200 words. The abstract should be followed by the Introduction, Materials and Method, Results, Discussion and Acknowledgement. In general, spelling conventions as found in Oxford Dictionary of English should be followed: e.g. Colour (not color).

                The SI units should be used for all scientific and laboratory data; if in certain instances, it is necessary to quote other units, these should be added in parentheses, temperature should be given in degree Celsius.

The abbreviations for units should follow the suggestions of the British Standard publication BS 1991. There is no need to use full stop to mark abbreviations, e.g. M (not M.) ppm (not p.p.m.)

Current recognize (IUPAC) nomenclature should be used, although commonly accepted trivial names may be used where there is ambiguity.

Tables (numbered consecutively with Arabic numerals), references and legends to illustrations should be typed on separate sheets and placed at the end of the paper.

Footnotes should be avoided as far as possible if they contain information which could equally well be included in the text.

REFERENCES

For references to published works, the Harvard system should be adopted i.e. name of author(s) and date of publication should appear in the text e.g. Oputa (1997) or Ackman et al. (1967). Unpublished data or private communication should not appear in the reference list. Examples of references are given below:
