Review Papers

NJES accepts review papers exclusively from authors who have been publishing papers in an Engineering specialized field, or an Interdisciplinarity field with Engineering such as biomedical engineering, for at least five years prior to submitting their review manuscript to our journal. 

NJES requires (20-25) listed references for research papers, and (over 50) listed references for review papers to be accepted in our journal. 



Useful Information Regarding Research Papers and Review Papers

  1. Purpose

While research papers aim to conduct and report an original investigation of a specific research question, presenting a particular point of view by the author/s, a view paper aims to conduct a critical analysis of previously published literature on a specific topic.

  1. Basis

Research papers are primary literature based on research that has been conducted by the author/s of the paper. Review papers, on the other hand, are secondary literature based on existing published articles and not an original research conducted by the author/s.

  1. Writing

Research papers are written to answer a certain question/s, collecting data and conducting an original study to write an analysis and interpretation of this data.

In review papers, authors select a specific topic and summarize existing literature on that topic. Their work attempt to present an overview of that topic’s current state of understanding. The length of the article (word count) depends on the journal for each type of research.

There are three main types of review papers; Domain-based, theory-based, and method-based.


  1. Reporting

Research papers report each step of the study in details. It includes an abstract, the hypothesis, background study, methodology, results, and an interpretation of the findings. It includes a discussion of the possible indications of the results and how the study contributes to existing literature, as well as suggestions for future research which are included in the conclusion section.

Review papers recognize and report commonalities between results of a certain topic. Wherever inconsistencies are found, the author/s try to provide the reasons for any conflicting results. Author/s analyze data and information from published works with a balanced perspective then report any problems or gaps within existing literature, as well as future study/research possibilities in the conclusion.
