Introduction

Tanzania Journal of Science is a peer reviewed journal published quarterly in print and/or electronic form by the College of Natural and Applied Sciences, University of Dar es Salaam. This journal accepts high-quality contributions of original work in the fields of natural and applied sciences as full research papers, review articles and short communications. The journal operates a blind review process and authors are required to provide full contact details (including institutions, email addresses and telephone numbers) of four (4) potential reviewers. Only one of the suggested reviewers may be from the same institution as the author. All manuscripts go through at least one round of review, usually two to three, although sometimes can be more than three. Each manuscript is initially evaluated by the Chief Editor and/or subject editor for checking suitability of the content for the journal. That paper judged by the editors to be of insufficient scientific interest or generally unsuitable is rejected promptly without formal review. The paper deemed suitable is then sent to at least two expert reviewers (typically two to six reviewers) to assess the scientific quality of the paper. Quality reports from at least two reviewers are required to make a reliable decision. Editors and reviewers should treat the articles they handle with confidentiality and should not use knowledge of the work before its publication to advance their own interests. Reviewers will remain anonymous. In conclusions of their reports, the reviewers/referees are required to recommend one of the following options: (i) Accept without revision, (ii) Accept after minor revisions, (iii) Accept after the major revisions/changes suggested, (iv) Reject but may be revised and resubmitted for re-evaluation, or (v) Reject. The revised manuscripts and author(s)' responses to the reviewers' comments are evaluated by the subject editors and Chief Editor. Manuscripts recommended major revisions are sent back to the reviewers for re-evaluation. The Chief Editor is responsible for the final decision concerning acceptance or rejection of papers.

Journal History

The Tanzania Journal of Science (Tanz. J. Sci.), formerly known as "University Science Journal" was established in 1975 as a forum for communication and coordination between and among scientists and allied professionals. It is intended as a medium for dissemination of scientific knowledge among scientists, practitioners and the public at large to promote the advancement of natural and applied sciences.

The journal is published by the College of Natural and Applied Sciences (formerly known as Faculty of Science (1965-2009), University of Dar es Salaam, Tanzania. From 1975 to 1984, the journal was published in print form under the name "University Science Journal" and from 1985, the journal's name was changed to Tanzania Journal of Science (TJS) to reflect the scope of the journal. The journal is managed by the college, whereby the college management appoints the Chief Editor and the Editorial Board each triennium of three years. The day-to-day running of the journal is therefore under the Chief Editor and the Editorial Board.

In the subsequent sections, the history of the journal is presented in descending order since the time of the First Issue, Published in January 1975. The inventory presents names of scientist involved in publication of various volumes, issues and number of papers published under their respective editorship.
