Author Guidelines

Aim and Scope
The Nigerian Journal of Technological Development publishes high-quality articles focusing on all aspects of Engineering and Applied Sciences. All manuscripts will be double blind peer-reviewed and if found suitable, published according to the subject matter, either as a Research Paper, Review Paper or a Technical Note.

Submission of Manuscript
Submission of manuscript is on the condition that it is an original work of the author(s) and it has neither been published previously nor currently under consideration for publication elsewhere. Authors should submit the electronic copy of their manuscript directly to the journal through the journal's website using the online submission system. Please do not submit a hard copy to the editorial office or send your manuscripts by e-mail unless you are facing some difficulties in uploading it on the portal.
After the manuscript has been submitted, you will see a confirmation screen and receive an email confirmation stating that your manuscript has been successfully submitted. If you do not receive this, your manuscript will not have been successfully submitted to the journal and the paper cannot progress to peer review. If this is the case your manuscript will still be sitting in the 'Incomplete' section of your 'Author Page' awaiting your attention.
To track your submission's progress through the review and editorial process, you will need to log into the journal website, and choose your role as Author. Click on the linked title to go to the submission record.

Complimentary Copies
Since authors can always download their published papers from our website at www.njtd.com.ng, author’s complimentary copy shall no longer be sent to the authors. However, any author that so requires a print version of the journal shall pay a sum of four thousand Naira (N4,000:00) per copy.

NJTD Publication Ethics

The Nigerian Journal of Technological Development (NJTD) observes ethical standards for its publications to ensure high quality, public trust in scientific findings, and that credits are given to the original owners of the ideas used by authors. To this end, members of public are requested to take note of the following information:

Data fabrication and falsification: NJTD takes exception to fabrication and falsification of data used in their works submitted to the journal. Published articles, which are later discovered to be guilty of this offence shall be retracted and such information publicised to our readership immediately.

Plagiarism detection: NJTD uses an anti-plagiarism software to detect matches of the submission with the existing texts. Any submission with a similarity index greater than 20% will be returned to the corresponding author to rework before such work can be passed to peer review. However, a manuscript with a significantly high similarity index will be rejected instantly at that level.  

Multiple submissions: It is unethical for authors to submit a single manuscript to different journals concurrently. Authors who desire to submit an already submitted article with another journal must forward to NJTD Managing Editor evidence of withdrawal from the first journal.

Redundant publications: This means publishing different versions of a very similar manuscript based on the same experiment or study. It can easily result in self-plagiarism, which should be avoided by authors.

Improper author contribution or attribution: Authors are advised to ensure that all listed authors make a significant scientific contribution to the research in the manuscript before listing their names as co-authors.   

COPE policies: NJTD endorses the policies of Committee on Publication Ethics (COPE), including those that cover overlapping publications.

Peer review process: Authors are encouraged to download the article processing flowchart from our homepage. The document summarises the peer review process used by NJTD.

Confidentiality of submissions: Reviewers are strongly advised against showing or discussing manuscripts allocated to them with colleagues and/or the authors. This is necessary to keep the submitted document as confidential as possible. This warning also applies to invited reviewers who decline the review invitation.

Reviewer’s promptness: Any invited referee who does not possess the required expertise or has it but will be unavailable to carry out the assignment is requested to immediately notify the Managing Editor to decline the review invitation. This is necessary to avoid any unnecessary delay in the peer review process. 

Notification of fundamental errors in published works: It is the obligation of the authors who discover significant errors or inaccuracies in their own published work to notify the Managing Editor promptly in order to take an appropriate action in due course.

Access to journal contents: The publisher, Faculty of Engineering & Technology, University of Ilorin, is committed to ensuring that published scholarly research findings are permanently made available online as well as in print form. This would guarantee express access to them at any time.

Article Publication Charge

The Nigerian Journal of Technological Development (NJTD) is an open access journal. As a result, publishing of an article in the Journal requires an Article Publication Charge (APC), which will be billed following the acceptance of the article. Aside from this, the Journal does not impose any other charge on the author, be it submission charge or colour charge.

The APC will be charged based on the corresponding author’s affiliation. Where the corresponding author has a dual affiliation, the affiliation of where the work was carried out will be used. For the corresponding authors based in Nigeria, the APC of ₦45,000.00 (NGN) will be imposed while $150.00 (USD) will be imposed on corresponding authors outside Nigeria. The publication fee is non-refundable once the article is published online. Payment can be made by International Bank wire transfer, Western Union money transfer, MoneyGram, Online money transfer, or Payoneer.

Payment instructions will be sent to the corresponding author by the Managing Editor after the acceptance of the paper. The evidence of payment should be uploaded on the portal against the submission immediately after payment.
