- NJP operates as a fully open access journal. Reproduction of any published content requires proper citation and acknowledgement of the original source.
- The Editorial Office endeavours to ensure accuracy in all published material; however, the entire responsibility for the correctness and integrity of data, results, and statements rests with the authors.
Ethical Considerations
- Authors must declare any potential conflicts of interest at the time of submission.
- Research involving human subjects or animals must comply with applicable ethical standards and have obtained the necessary approvals.

- Line Numbering: Continuous, restarting on each page
Manuscripts should be organised under the following headings (without numbering):
- Article Title
- Authors and Their Full Addresses
- Abstract (maximum 300 words)
- Keywords (maximum of five)
- Introduction

Title
The title should be concise and clearly convey the nature of the paper. If the work was presented wholly or partly at a scientific meeting, this must be noted in a footnote.
Authors and Affiliations
Provide one surname followed by the initials of each author, along with the institution where the work was conducted. Clearly indicate the name, address, and email address of the corresponding author.
Abstract
A single paragraph of no more than 300 words summarising the background, objectives, methods, key findings, and conclusions of the study.
Keywords
Provide up to five relevant keywords to facilitate indexing and discoverability.
Introduction
State the problem investigated, the objectives of the work, and cite relevant prior studies. The section must clearly articulate the knowledge gap and the contribution of the present research.
Materials and Methods
Provide sufficient detail to allow independent replication. Only novel techniques need full description; established methods should be referenced appropriately.
Results and Discussion
Present results clearly and concisely, using tables or figures where helpful. The discussion should interpret findings in relation to the existing body of literature.
Conclusion
Summarise the key findings, highlight their implications, and offer recommendations where applicable.
Figures and Tables
- Only high-resolution figures will be accepted: minimum 300 DPI for photographs, and minimum 800 DPI for graphs and drawings.
- Graphs should be prepared in CorelDraw or Microsoft Excel. Acceptable file formats include JPEG, TIFF, and MS Word.
- Tables and figures must be numbered consecutively with clear, self-explanatory captions and integrated into the text at the relevant points.
- Lettering on figures should be kept to a minimum; essential details belong in the legend.
Symbols, Formulae, and Equations
Symbols and equations must be written with care. Follow the symbols recommended in the British Standard 1991. Use SI units as described in British Standards Publication PD 5686. All equations must be typeset using Microsoft Equation Editor.
References
Use the American Psychological Association (APA) referencing style. In-text citations:
- One author: (Michael, 2002)
- Two authors: (Ogbe & Segun, 2009)
- Three or more authors: (Haruna et al., 2005)
References should be listed in alphabetical order at the end of the paper. Provide all authors with initials after their surnames, the full title of the paper, the journal title in italics (abbreviated per Chemical Abstracts or Biological Abstracts), volume number in bold, first and last page numbers, year in parentheses, and the DOI where available.
