Editorial Policy
The following policies govern all submissions to NJTEP:
- A manuscript submitted to NJTEP must not have been previously published, nor may it be under simultaneous consideration at any other journal, either in full or in part.
- Upon acceptance, the copyright of the article is transferred entirely to the NJTEP Editorial Board. By submitting, authors grant the journal the right to publish and distribute the work electronically, in print, and through any abstracting or indexing service worldwide.
- Every submitted article is subjected to peer review prior to a publication decision being made.
- All manuscripts are screened for originality using a similarity detection tool. Articles with a similarity index above 35% are rejected outright; those between 20% and 35% must be revised to reduce the index before the review process can continue.
- No part of any NJTEP publication may be reproduced, stored, or transmitted in any form without the prior written consent of the copyright holder.
The Editorial Office endeavours to ensure that no inaccurate or misleading content appears in the journal. Nevertheless, full responsibility for the accuracy and integrity of all data, results, and statements rests with the authors. The Editorial Board and its agents accept no liability for any consequences arising from misleading information provided by authors.

Title
The title must be concise and accurately reflect the content of the paper. Where the work was presented, wholly or in part, at a scientific conference, this should be noted in a footnote on the title page.
Authors' Names and Affiliations
List each author by surname followed by initials, along with the full institutional address where the work was undertaken. The name, postal address, and email address of the corresponding author must be clearly indicated.
Abstract
Provide a single paragraph of no more than 300 words. The abstract should concisely cover the background and objectives, the methods employed, the key results, the significance of the findings, and the conclusions drawn.
Keywords
Provide a maximum of five keywords that accurately represent the subject matter of the paper, to assist in indexing and retrieval.
Introduction
State the research problem, the objectives of the study, and summarise relevant prior work with appropriate citations. The introduction must clearly identify the gap in knowledge that the present study addresses and describe the contribution it makes.
Materials and Methods
Describe the methodology in sufficient detail to allow independent replication. Only novel techniques require full description; established methods may be referred to by citation. Include all relevant statistical procedures.
Results and Discussion
Present results concisely, using tables or figures where they aid clarity. The discussion should interpret the findings critically in the context of the existing literature, addressing their significance and limitations.
Conclusion
Summarise the principal findings and discuss their theoretical or practical implications. Offer recommendations for future research where appropriate.
Figures and Tables
- Only clearly readable, high-resolution figures are accepted. Minimum 300 DPI for photographs; minimum 800 DPI for graphs and line drawings.
- Graphs should be prepared using CorelDraw or Microsoft Excel. Acceptable file formats: JPEG, TIFF, and MS Word.
- Number all illustrations consecutively with Arabic numerals in order of appearance. Minimise lettering on figures; all essential information should be placed in the legend.
- Figures and tables should be embedded in the text at the point of first reference, with concise, self-explanatory captions. Figures must be submitted in black and white without background colour.
- Tabular material must have clear, concise headings allowing the table to be understood independently of the main text. Data in columns must be consistent in the number of significant figures.
Symbols, Formulae, and Equations
All symbols, formulae, and equations must be prepared with care, following the British Standard 1991 for recommended symbols. Use SI units throughout, as described in British Standards Publication PD 5686 (The Use of SI Units). All equations must be typeset using Microsoft Equation Editor.
References
Use the American Psychological Association (APA) referencing style throughout. In-text citations:
- One or two authors: cited in full — e.g. (Michael, 2002) or (Ogbe & Segun, 2009)
- Three or more authors: (Haruna et al., 2005)
References must be listed in alphabetical order at the end of the manuscript. For each reference, provide all author surnames followed by initials, the full paper title (or an accurate English translation), the journal title in italics (abbreviated per Chemical Abstracts or Biological Abstracts; given in full if not listed there), volume in bold, first and last page numbers, and year in parentheses. Include the DOI where available.
