Preparing your Manuscript

Please format the manuscript in the following way to expedite the review process:

  1. Manuscript organization:
    • All manuscripts are expected to be prepared as a single PDF or MS Word document with the complete text, references, tables and figures included. Any revised manuscripts prepared for publication should be sent as a single editable Word document.
    • Manuscripts should be written in English. Title, author(s), and affiliations should all be included on a title page as the first page of the manuscript file, followed by a 300 word abstract and 3-5 keywords. The order they follow is: Title, Authors, Affiliations, Abstract, Keywords, Introduction, Methodology, Results, Discussion, Conclusion and References.
  2. Title: Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
  3. Author names and affiliations: Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. You can add your name between parentheses in your own script behind the English transliteration. Present the authors' affiliation addresses below the names. Indicate all affiliations with a superscript number immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
  4. Corresponding author: Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.
  5. Abstract and Key Words: The abstract of the manuscript should not exceed 300 words and must be structured into separate sections for original articles: Background of the study, Aim of the study, Material and methods (how the study was performed and statistical tests used), Results (the main findings), Conclusions.
  6. Introduction: State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results. In a separate line, 3 – 5 key words or short phrases that are not found in the title or abstract should be included to assist indexers in cross-indexing the article.
  7. Material and methods: Provide sufficient details to allow the work to be reproduced by an independent researcher. Methods that are already published should be summarized, and indicated by a reference. If quoting directly from a previously published method, use quotation marks and also cite the source. Any modifications to existing methods should also be described.
  8. Results: Results should be clear and concise.
  9. Discussion: This should critically evaluate and analyze the results and its significance. Results should not be repeated. The discussion should be logical, clear, and informative, drawing inferences only from the results of the study, and comparing findings with similar previous works. This should explore the significance of the results of the work, not repeat them. Avoid extensive citations and discussion of published literature.
  10. Conclusions: The main conclusions of the study may be presented and need not be as elaborate as the discussion.
  11. Figure and Table Requirement: All figures or photographs must be submitted as jpg or tif files with distinct characters and symbols at 500 dpi (dots per inch). Tables and equations should be in an editable rather than image version. Tables must be edited with Word/Excel. Equations must be edited with Equation Editor. Figures, tables and equations should be numbered and cited as Figure 1, Figure 2, Figure 3, etc. in sequence.
  12. Page numbering and Formatting: Before submission, type your manuscript single spaced, and make all the characters in the text, tables, figure legends, footnotes and references in a single typeface and point size as 12 pt Times New Roman.
  13. Letters to the Editor: should have a maximum of 400 words, one table or figure and not more than five references. No summary is necessary and headings, apart from 'References', are optional. Authors' names and addresses should be listed at the end of text, before the references.
  14. References: Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Unpublished results and personal communications are not allowed. All references should be indicated by superscripted numerals in the text and listed in the References section in the order they appear in the text (Vancouver style). Titles of journals should be abbreviated according to Index Medicus or given in full. References must include: (i) all authors' surnames and initials (if there are six authors or fewer) or (if there are seven or more) the first three authors, followed by et al.; (ii) the full title of the paper; (iii) the title of the journal; (iv) the year of publication; (v) the volume and issue number; (vi) the first and last page numbers. Groups of references should be listed first alphabetically, then chronologically. Example: ‘as demonstrated (Dimkpa, 2017a, 2017b, 2014; Umunnah and Ugwu, 2014). Citation of chapters in books should include the author(s) and title of the chapter, editors' names, title of the book, city of publication, name of publisher, year of publication and page nos if appropriate.

Submission of Article

Submission of all manuscripts is done online through [email protected]

 Peer Review Process

All contributions submitted to the journal will be initially assessed by the Editorial Board for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor-in-chief is responsible for the final decision regarding acceptance or rejection of articles.

After Acceptance

  1. Proofs: One set of page proofs (as PDF files) will be sent to the corresponding author. The author should list all corrections quoting line numbers. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and scan the pages and return via e-mail. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Once the proof is received from the authors, and the publication charges paid, we will do everything possible to get your article published quickly and accurately.


The corresponding author will be notified and receive a link to the published version of the open access article. For an extra charge, paper off-prints may be purchased and should be ordered when the proofs are returned. Off-prints and a complete copy of the relevant journal issue will be sent about 3 weeks after publication.
