Electronic Submission:
PJN will encourage to submit manuscripts through e-mail for evaluation. Author(s) should sent their manuscript to the Editor's e-mail address: editorpjn@gmail.com OR pjn@fsd.comsats.net.pk

By Regular Mail:
Triplicate copies of the manuscript should be sent, each with a set of original figures and photographs, typed on one side, (with numbered lines) double spaced and an IBM formatted floppy diskette of 3.50 size containing the manuscript should be accompanied (mentioning file names, in Microsoft Word).
Manuscript should be submitted to:

Submitted manuscripts will be assessed from Editorial points of view, at first, and if the manuscript is found appropriate for publication, it will enter the peer-review process. To ensure an unbiased review, referees will receive the blinded version of the manuscript. The corresponding author will then be informed of the evaluation along with the Editorial remarks. The authors of the accepted articles will be asked to provide their article either on a floppy diskette or via e-mail: editorpjn@gmail.com OR pjn@fsd.comsats.net.pk The preferred word processing program is Microsoft Word for PC or WordPerfect. The Journal discourages the submission of more than one article dealing with related aspects of the same study.

Title page:
The title of the paper must be brief and contain words useful for indexing (avoid serial titles) the full name and affiliation of all authors. If an author's affiliation has changed since the work was done, list the new affiliation as well. The address for communication (along with e-mail address, telephone, and fax numbers, if available), should be given.

Structure of Articles:
Articles should include Abstract (should not exceed 250 words), Key words (3-6), Short running title (upto 40 characters including spaces) Introduction, Materials and Methods, Results, Discussion and References sections. Do not use Reference citation in Abstract. The Editorial Office reserves the right for editing the submitted manuscripts to fit PJN formate. In any case, the authors are responsible for the published material.

References:
All publications cited in the text should be presented in a list of References following the text of manuscript. The manuscript should be carefully checked to ensure that the spelling of author's names and dates are exactly the same in the text as in the Reference list. In the text refer to the author's name (without initial) and year of publication, followed if necessary by a short Reference to appropriate pages. Examples: "Since Abdel-Salam (2000) has shown that..." "This is in support with results obtained later (Kutrup, 2000)". If Reference is made in the text to a publication written by more than two authors the name of the first author should be used followed by "et al.". This indication, however, should never be used in the list of References. In this list names of first author and coauthor should be mentioned.
