Information for Authors
1. Science Diliman is a journal of pure and applied sciences published by the University of the Philippines through the Office of the Vice-Chancellor for Research and Development (OVCRD). Considered for publication are primary and original papers. Review articles may occasionally be accepted. In all other cases, papers should present new and previously unpublished material.
2. Contributions must be in English and should not have been submitted for publication elsewhere.
3. Manuscripts are selected for publication according to editorial assessment of their suitability and reviews of independent referees. They will be sent to two or three reviewers, chosen for their expertise. Contributors may suggest reviewers.
4. Submission of a manuscript implies: that the work described has not been published before (except in the form of an abstract or as part of a published lecture, review, or thesis); that it is not under consideration for publication elsewhere; that its publication has been approved by all co-authors, if any, as well as by the responsible authorities at the institute where the work has been carried out.
The letter to the editor usually contains these: that, if and when the manuscript is accepted for publication, the authors agree to the automatic transfer of the copyright to the publisher; that the manuscript will not be published elsewhere in any language without the consent of the copyright holders; that written permission of the copyright holder is obtained by the authors for material used from other copyrighted sources; and that any costs associated with obtaining this permission are the authors’ responsibility.
5. Authors must submit electronically prepared manuscripts in Microsoft Word.
6. Manuscripts should be formatted for A4 paper, double-spaced, with 1" margins on all sides. Each page of the manuscript must include continuous line numbers in the margin. All pages should be numbered consecutively on the upper right hand corner of the page.
7. Page 1 should contain the article title, author(s), affiliation(s), and the name and complete mailing address (and telephone number, fax number, and e-mail) of the person to whom correspondence should be sent.
8. Page 2 should contain a short abstract of not more than 250 words. The abstract should contain facts and conclusions, rather than citation of the areas and subjects that have been treated or discussed. The abstract should start with the hypothesis or a statement of the problem to be solved, followed by a description of the method or technique utilized to solve the problem. The abstract should end with a summary of the results that were obtained and their implications. It is to be followed by a maximum of six key words. The author must also submit a layman’s abstract of not more than 200 words.
9. The paper should be organized as follows:
Abstract and Layman’s Abstract
Materials and Methods
Results and Discussion (or Results separate from Discussion)
10. Reference lists, figures, tables, and figure/list captions should all be on separate sheets, all of which should be double-spaced, and numbered. Standard nomenclature should be used. Unfamiliar terms, abbreviations, and symbols must be defined at first mention.
11. References to the literature citations in the text should be by author and year; where there are two authors, both should be named; with three or more only the first author’s name plus “et al.” need to be given.
References in the text should follow the Council of Science Editors (CSE) Scientific Style and Format, 7th Edition, 2006.
