Peer-reviewed – Manuscripts submitted to RJEES are taken through a rigorous peer review process to ensure that high quality articles are published.

Open Access – Articles published in RJEES are free from all restrictions of access as we adopt the open access model of publication which means that your article will be available immediately and freely upon publication. This ensures that you reach a wider audience and have more citations

Online Submission System – RJEES has an efficient and user friendly manuscript submission system that simplifies the manuscript submission process.

Rapid Publication – RJEES strives to ensure that the time period between manuscript submission and final publication is reduced as much as possible while still maintaining excellent quality control.

Author Guidelines All manuscripts must be prepared in English and in Microsoft Word format using on a 12 point font-face of Times New Roman. Manuscripts are submitted to this journal with the understanding that they have not been previously published neither are they currently under consideration for publication elsewhere. Also, it is considered 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. Hence, authors are required to certify in a cover letter stating that "This manuscript has not been previously published, nor is it currently under consideration for publication in another journal" Prior to submission, authors are encouraged to take advantage of professional language editing and copyediting services. The author will however bear the cost of such services. A manuscript template is available for download to guide authors in the preparation of their manuscript.

This journal considers three types of manuscripts for publication:

Original Research Articles: These should describe original and carefully execute studies and investigations.

Short Communications: A short communication is suitable for urgent reporting of the preliminary results from a small investigation or a pioneer study because of its high interest and originality.

Reviews: Submissions of reviews covering topics of current interest are also welcome.

Manuscript Style: The language of the journal is English. Each manuscript should be typed double-spaced on A4 (8.5" x 11") paper with 0.6 inch margins on either side and 0.8 inch margins at the top and bottom. It should be arranged in the following order: Title, Abstract, Keywords, Introduction, Materials and Methods, Results and Discussion, Conclusion, Acknowledgement, References.

The maximum page length should be 5, 20 and 25 pages for Short Communication, Original article and review paper, including text, references, tables and figures. Headings should be set in bold (font size 12 pt) and aligned flush left.

The corresponding author should be clearly indicated. The E mail and telephone number of the corresponding author should also be provided.

: Each manuscript should have a concise abstract of not more than 200 words. The abstract should convey the background and motivation for the study, the methodology adopted, major findings and conclusions. No literature should be cited in the abstract and the use of special abbreviations should be avoided.

Keywords: Please provide about 5 to 7 key words that will be used for indexing purposes Introduction 
The introduction should provide a clear statement of the research problem, a background to the study and relevant literature on the subject. It should be clear and easily understood by readers from a broad range of fields.

Materials and Methods: This section should provide information on how the study was carried out. The procedures adopted should be reported in sufficient detail to allow for easy replication by other researchers.

The source of the materials used in the study should be state where possible. Only new procedure should be described in detail while previously reported procedures should be cited. Important modifications to already published procedures should also be reported. The section may be divided into subsections, each with a concise subheading.

Results and Discussion: The findings of the study should be presented with clarity and precision. It is advisable to present the results using the past tense. The results should then be discussed by comprehensively analysing and interpreting trends and relationships observed in the results.

The results should be interpreted and compared to the results of previous researchers on the subject. This section may also be divided into subsections with each having a concise subheading.

Conclusions: The major conclusions drawn from the findings of the study should be presented in this section. This should highlight the significance of the study and show how the research problem has been solved.

The author could also point out any remaining gaps in knowledge thereby paving way for further research.

Acknowledgements: The authors should acknowledge any support received in the course of carry out the study. This could be in the form of funding for the research and assistance provided by persons.

Conflict of Interest : Authors must declare the presence or absence of conflicting interests. In the absence of any, the authors should indicate “There is no conflict of interest associated with this work”.

References: It is the responsibility of authors to ensure that references are complete and accurate. 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).

When there are more than two authors, only the first author‘s name should be mentioned, followed by ’et al‘. Papers by the same author in the same year should be identified by lower case letter such as ‘a’, ‘b’, ‘c’ after the date to distinguish the works. Examples include Aluyor (2013), Kontoravdi et al. (2010), (Obahiagbon et al., 2009), (Amenaghawon and Aisien, 2012), (Amenaghawon et al., 2014a,b; Ballesteros et al., 2008; Onohaebi, 2005).

A list of cited references should be presented in alphabetical order at the end of the manuscript. All references cited in the work should be found in this list and vice versa. Unpublished work should not be included in the list of references. The list of references should be done in the following format.

Each figure must be numbered consecutively as Figure 1, Figure 2 etc. Each figure should have a caption below it that provides sufficient description of the figure. The same data should not be presented both as a table and as a figure.

Equations: All equations should be written using equation editor and numbered consecutively using Arabic numerals in parenthesis on the right hand margin. The equation should be referred to in the text as Equation (1), Equation (2) etc. All variables must be expressed in S.I units.
