Main title

The title should be brief (not exceeding 19 words in length), clear and reflect the content of the manuscript. The title must be centered and bolded with capitalized initials.

Use sentence case for the abstract title, aligned to the center and bolded, whereas the abstract body to be justified in one block. The abstract should be written in the past tense, and should not exceed 300 words.


As stated above, 4 – 7 keywords reflecting significant issues in the text are required to be written immediately below the abstract. You should not repeat the same words of title in keywords. 


The introduction should give clear background on the problem under investigation depending on relevant and up to date literature. It needs to clarify the hypothesis justification and to be concluded with understandable solid objective(s). Such objectives are advisable to be written untitled in a separate paragraph at the end of the introduction.

Materials and Methods

This section should describe the research methodology applied in an understandable way to permit reproduction of relevant works, besides providing citations for critical works. For new tools, techniques or procedures the author(s) are required to provide scientific and statistical verification or clear cut explanation based on literature to support his/their approach.

Results and Discussion

Results and discussion may be written separately, but it is advisable to be joined. The data may be presented in tables or figures, but not both for the same results. Photos are not desirable unless of significant importance, if so graphics and photos should be of high resolution applying proper recent software programs. Statistical analyses of data using standard methods are recommended. However, presented results should be discussed properly on light of obtained findings, and consulted literature. Concrete conclusion(s) answering the stated objectives is/are required.

Tables and Figures

Tables and figures should be designed in simple manners, self explanatory and with reasonable sizes. Use brief titles numbered in Arabic numerals, and arrange them consecutively at the end of the text before the references, each in a separate page. Don’t repeat the same data in table(s) and figure(s).


References should be arranged alphabetically based on authors’ surnames (Harvard). 

In text: Put family names of authors plus the reference date in parentheses as explained in the following examples:

  • One author – (Ali, 2010); two authors – (Ali and Mohamed, 2010); three or more authors – (Ali et al., 2010).

When authors mentioned in the text, only reference(s) dates are given in parenthesis, as follows:

  • Ali (2010) stated …; Ali and Mohamed (2010) mentioned …; Ali et al. (2010) … etc.

When two or more works of similar dates are used for the same author(s), you differentiate by adding a lower case letter after the date as shown below:

  • (Ali, 2010a; Ali, 2010b); Ali (2010ab) stated … etc.

When there are two or more references, they should be arranged according to their dates, as follows:

  • (Ali, 2010, and Mohamed, 2014); (Ali, 2007; Mohamed, 2010, and Singh et al., 2012)
