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 and short

communications 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should present new and previously unpublished material.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



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), aff iliation(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 f irst author’s name plus “et al.” need to be given.


References in the text should follow the Council of Science Editors

12. The list of references at the end of the paper should include only works

mentioned in the text and should be arranged alphabetically by the

name of the author.


13. Responsibility for the accuracy of bibliographic references rests entirely

with the author, who is requested to use as few “in press” citations as

possible. “In press” citations must include the name of the journal that

has accepted the paper.


14. Footnotes in the text should be numbered consecutively. Footnotes to

the title or authors of the article are marked by asterisks and placed on

the title page.


15. Figures and graphs should always be mentioned in the text and

numbered with Arabic numerals. A brief descriptive caption should be

provided for each figure or table on a separate page. At the lower hand

corner, the name of the author and the figure number should be



16. Illustration hard copy should comprise:


Line drawing should be of good quality and should not exceed 8 1/2" x

18. Mathematical equations should be clearly presented so that they can

be interpreted properly.


19. Obscure primes, symbols, and dots must be brought to the attention of

the printer. Distinguish very clearly number 1 and letter l. Use fractional

exponents instead of root signs and the solidus (/) for fractions wherever

their use will save vertical space.


20. All equations must be numbered sequentially in Arabic numerals in

parentheses on the right-hand side of the equations.


21. The authors should follow internationally accepted abbreviations,

Editors (CSE) Scientific Style and Format, 7th Edition, 2006.


22. Less common abbreviations may be printed as footnotes.


23. Short communications must be guided by the following points:


• Short communications are reports of limited data or important findings

that warrant publication before the completion of the study;

• Short communications are reports of significant new data arising from

problems with narrow, well defined limits before broader studies are

completed; and results have not been published in print elsewhere,

except as partial communications or posters in conference


• Short communications should not be divided into conventional

sections like Introduction, Methodology, etc. but should be provided

with keywords, full names and addresses of all authors, current

addresses, email addresses, and contact person to whom queries and

proofs should be sent;

• Abstracts will be required on submission but not to be part of the
