Author Guidelines

Submission of manuscript
Manuscripts prepared in MSword should be submitted online. Visit our website and follow the links to submit. Papers are accepted on the understanding that the work described is original and has not been published elsewhere and that the author has obtained any necessary authorization for publication of the material submitted. Submission of a multi-authored manuscript implies the consent of all the participating authors.

Preparation of Manuscript
Manuscript should be written in the third person in an objective, formal and impersonal style. The SI system should be used for all scientific and laboratory data. The full stop should not be included in abbreviations, e.g m (not m.) ppm (not p.p.m.). All mathematical expressions should be included in the manuscript. Care should be taken to distinguish between capital and lowercase letters, between zero (0) and letter (O), between the numeral (1) and letter (I), etc. Mathematical expressions should fit into a single column when set in type. Fractional powers are preferred to root signs and should always be used in more elaborate formulae. The solids (/) should be used instead of the horizontal lines for fractions whenever possible. Numbers that identify mathematical expressions should be enclosed in parentheses. Refer to equations in the text as “Eq. (1)”, etc., or “Equation (1)”, etc., at the beginning of a sentence.

Content
All pages must be numbered consecutively. A manuscript would normally include a title, abstract, keywords, introduction, materials and methods, results and discussion, conclusions and references.

1. Title page. A short title which should be concise but informative must be provided. This should be followed by the names and full addresses of all authors. Telephone numbers and e-mail addresses of the corresponding authors must be included.
2. The abstract should not be more than 220 words. It should give concise factual information about the objectives of the work, the methods used, the results obtained and the conclusions reached.
3. Contributors should list below the abstract keywords for information retrieval purposes. The keywords should identify with the main points in the paper and should not be more than five.
4. Abbreviations and Notations. Nomenclature must be listed at the beginning of the paper and should conform to the system of standard SI units. Acronyms and abbreviations should be spelled out in full at their first occurrence in the text.
5. Papers should be typed double column, with single line spacing on one side of the paper only with ample margins on all sides. Use Times Roman font 10. The text should be divided into sections each with a separate heading, numbered consecutively. The section heading should be typed on a separate line and should not be underlined
6. Conclusions and Recommendations. The conclusions should summarise the findings, clearly stating the contributions and their relevance. Recommendations for implementation or for areas of further work on the subject matter should be made.
7. These should be brief and relevant. The names of funding organizations should be written in full. Dedications are not permitted.
8. References to published work should be indicated at the appropriate place in the text, according to the Harvard system (i.e. using author(s)’ name(s) and date), with a reference list in alphabetical order, at the end of the paper. All references in this list should be indicated at some point in the text and vice versa. Papers by more than two authors but with same first author should be listed by year sequence and alphabetically within each year. Examples of layout of references are given below.

9. Figures and Tables. All figures whether line drawings, graphs or photographs should be given a figure number by Arabic numeral in ascending numerical order as reference is first made to them in the text (e.g. Fig.3). Tables are to be similarly numbered. Captions of figures should be below the respective figures while captions of tables should be above the respective tables. The measured quantity with the units, usually in brackets, and the numerical scale should be given alongside the ordinate and abscissa of every graph.
