{{ t.authorGuidelines }}

General

The work of editor will be greatly facilitated if authors papers prepared in accordance with these guidelines. (This is after accepting the abstract by the editorial board).

Submission of a paper is understood to imply that it is original and has not been published previously, that it is not under consideration for publication elsewhere, and that if accepted it will not be published elsewhere in the same form, in English or in any other language.

Only manuscripts submitted electronically as Microsoft word document (docx.) will be considered for publication. The manuscript must be submitted in 1.15-line spacing format, justified alignment, font Times New Roman, size 12, (except the Titel, size 14) and normal margin on A4 paper size should be used. Keywords should be at least three and not more than six.

Figures and tables embedded in an Office file should be saved as JPEG format. However, the editor recommends sending all the figures and tables contained in the manuscript in another separate file.

Text

The first text page should contain the title of the paper, the name(s) of the author(s), their full postal address written as font Times New Roman, size 10, and an abstract. The abstract should not exceed 300 words. It should provide a summary of the main achievements of the paper. It should not contain references.

The paper should conform to the following scheme as closely as possible:

  1. Abstract.
  2. Introduction. (to include methods, techniques, material studies, etc.)
  3. Methodology.
  4. Results and discussion.
  5. Conclusions/summary.
  6. Acknowledgements.
  7. References.
  8. Appendix/ices. (If any).

Headings

Four grades of headings are normally used in the proceedings:

  1. FIRST-ORDER HEADING [capitals, centered].
  2. Second-order heading [italics, at the margin]. Text follows on 2nd line.
  3. Third-order heading [italics, at the margin] text follows on next line.
  4. Fourth-order heading [italics, at the margin]. Text follows on the same line.

If a further sub-division is needed, (1), (2), (3), etc. or (a), (b), (c), etc. Should be used.

Use Standard English spelling (oxford English dictionary) not standard American spelling. Note particularly the following: palaeontology, palaeolake, meter/s, kilometers/s, center, etc. it will be helpful if you sent the spell check on your word processor to “English (UK)”.

Measurements and Numbers

  • All measurements etc. should be metric and should follow the international system of units (SI), unless this is impossible (e.g., certain depth sounding machine read-outs, etc.).
  • Equations should be numbered serially on the right-hand side, in parentheses. In the text they should be referred to as “Eq. (1)”: within mathematics they may be referred to by numbers alone. Equations require normal punctuation.
  • Whole numbers of more than four digits are to be split into groups of three digits with spaces (NOT commas). Thus, to express thirty-two thousand one hundred and thirty-four: 32 134 (NOT 32,134). Four-digit numbers are kept together: 7341.
  • Decimal fractions should ALWAYS have the zero leading the decimal: 0.637 NOT .637.
  • There should NOT be a space between the degree symbol o and C or F, e.g., 37°C NOT 37° C. Likewise for sample numbers etc. 15a, 16b NOT 15 a, 17 b.
  • Use lower case “n” for the word “numbers/s” when it is abbreviated, e.g., “sample no. 3” “well no’s 6 and 9”, etc.

References

  • All references cited in the text and in the captions to figures and tables should be presented in list of references following the text, and vice versa-i.e. references not cited in the text or captions should not be included in the list. The manuscript should be carefully checked to ensure that the spelling of author’s names and dates given are the same in the text as in the references list. The accuracy of references is the responsibility of authors. Papers “in preparation” or “submitted” are not valid references. Work in preparation, unpublished abstracts, and personal and oral communications should be cited in the text but not in the reference list.
  • If references are made in the text to publications written by more than two authors, the name of the first author should be used followed by “et al.” this indication should NEVER be used in the list of references where names of all co-authors should be given in full.
  • References in the text should be arranged chronologically, e.g. “(Smith and Davidson, 1988; Hammuda et al., 1990; sebta and Busrewil, 1996)” or “according to Smith and Davidson (1988), depending on the context.
  • The list of references should be arranged alphabetically by authors names, and then chronologically (i.e. by date) for each author. If an author’s name in the list is also mentioned with co-authors, the following order should be used: publications of the single author, arranged according to publication date; publications of the same author with one co-author, arranged alphabetically by 1st author and by 2nd author; publications of the same author with more than one co-author, arranged according to publication date.
For example:
Single author (chronological) same author and one co-author (alphabetical)
Salem, M. (1980). Salem, M. and Abdullah, A. (2003).
Salem, M. (1991). Salem, M. and Busrewil, M. (1972).
Salem, M. (2003). Salem, M. and Yelavich, A. (1989).
Same 1st author and more than one co-author (chronological)
Salem, M., Taleb, A., and smith, J. (1989)
Salem, M., Abdullah, S., and Jones, M. (1991)
Salem, M., Smith, J., and Yelavich, A. (2002)

The following examples of references cited from various sources (journal article, books, etc) should be followed. Note that the author’s names are in the following format: Large capitals and small capitals- ‘Smith” and NOT “SMITH” (all capitals). If you find this difficult to do, please just use large capitals and lowercase-smith” as this format is easier for the editors to correct, than all capitals.
