Manuscripts submitted to ScienceAsia must conform to the guidelines of the journal. The manuscripts must be written in English, and should be divided into

(1) Title page - the title page contains title of the article, names of all authors, and indexing term. Title should be short, descriptive, and should not contain any abbreviations or subtitles. List the names of all authors (preferred given names, initial(s), and surnames), affiliations, complete addresses, and email address of the corresponding author. Please also provide 3-5 indexing terms not already mentioned in the title.

(2) Abstract - The abstract should be a concise summary of the manuscript of not more than 250 words. It should include a brief description of the methods, main results, and conclusions, and emphasize what is novel in the work. It should preferably not contain any citations. However, if a citation is essential, the details of the reference must be given as follows [authors, journal abbreviation, volume, page]. A well-written abstract will help potential referees to decide whether or not to review the manuscript based only on viewing the title and abstract.

(3) Introduction - give short review of literature with general background of the subject, current stage and remaining gap of knowledge, reason for carrying out the study and its relationship to reported works in the area, aim of the present study, etc.

(4) Materials and Methods - provide brief but sufficient information for others to be able to reproduce the experiments. Describe in detail any truly new methods/procedures, but cite in references if the procedures are already published. If the previously published procedures are modified, describe how you modified them and cite the references of the original published procedures.

(5) Results - presented results in text, figures, tables and graphs. Avoid redundant presentation in the text of the data already shown in tables or figures, nor use both figure and table to show the same data. Subheadings may help keep results of the same type together.

(6) Discussion - should be concise and not verbose. Discussion should contain interpretation of results presented in the manuscript, and discussion of the results agrees or disagrees with other published works.

(7) Acknowledgements - this part is for acknowledgement of individuals who helped the work, financial support, and institution, etc.

(8) References - should be indicated in the text by superior numerals in consecutive order. When references are mentioned by authors’ names in the text, they should still be designated by superior numerals. Proper citation is important, authors should cite proper and up-to-date references.

A reference to ScienceAsia article should begin with the author's surname followed by forename or initials (more than eight authors, use et al), year in full (in bracket), the title of the article, journal name (italic and abbreviated, see http://journalseek.net or http://www.library.ubc.ca/scieng/coden.html#A for Science and Engineering Journal Abbreviations), followed by volume number (bold) and page numbers. The styles of references for the journal and book are shown below:

       Journals:
       Fucharoen S, Winichagoon P, Siritanaratkul N, Chowthaworn J, Pootrakul P (1998) Alpha and beta thalassemia in Thailand. Ann NY Acad Sci 850, 412-4.

       Books:
       Farrell HM (1980) Physical equilibria: proteins. In: Webb BH, Johnson HM, Alford JA (eds) Fundamentals of Dairy Chemistry, 2nd edn, AVI Publishing Company, Westport, Connecticut, pp 442-73.

       Theses:
       Lawson LJM (1969) The multiplicative semigroup of a ring. PhD thesis, Univ of Tennessee.

(9) Tables and figures - Each table must be prepared on a separate page (type double-space), with a short descriptive title and sufficient details in the legend immediately following the title. Symbols and abbreviations should be defined in the legend. Footnotes must be used to define a, b, c, in the Table. Figures must be submitted in a suitable form for high quality reproduction (see below). Use (a), (b), (c), etc to label sub-figures. Lettering in the figures should be clear with adequate size to be legible after reduction. Half-tone illustrations could be accepted, provided that they have sufficient contrast. A scale should appear on photomicrographs. Colour plates are welcome if colour is necessary for contribution to the understanding of the information, but the authors will have to pay the charge for colour plates (contact editor@scienceasia.org for rate to print colour figures). Figure legends should be typed double spaced at the end of the text, not on the figures. Figures should be checked extremely carefully, particularly after revisions. No changes to figures will be allowed after the manuscript is accepted.

(10) Ethical Use of Animals - Manuscript reporting studies that involve use of animals MUST be accompanied by a statement from Institutional Animal Use and Care Committee, or similar body approving that animals received humane care according to the guidelines specified by the institution.

UP

Manuscripts can be prepared as LaTeX (.tex), OpenDocument (.odt), or MSWord (.doc) files. They must be submitted via the online submission system as .tex or PDF files. The PDF files should include all figures and tables. If the PDF file is larger than 2MB, please try to reduce the size by decreasing the resolution of the included figures. We only require high resolution figures if your article is accepted. Manuscripts with a heavy mathematical content will only be accepted as LaTeX files. LaTeX users must use the ScienceAsia class file (and, if they wish, the BibTeX style file) which can be downloaded from here. For the convenience of the referees, figures and tables may be included at the appropriate places within the text, provided the size of the resulting file is not excessive.

Abbreviations, symbols, chemical and biochemical nomenclature, etc., should be used appropriately. Avoid abbreviations which are not in common use across the field. Abbreviations used should be defined in the text on first usage and listed as a footnote on the title page. Do not introduce abbreviations unless they are used at least 4 times. Please make sure that the manuscript conforms to the journal style before submission as this will expedite the reviewing process. All Figures (graphs and maps) should be supplied as EPS (encapsulated postscript) files which can be generated directly from the graph or map drawing program used. Do not try to convert any other file to an EPS file. It is highly recommended that the authors upload the manuscript as small separated files, i.e. main body of the manuscript (in Word with line number, not PDF file), Figures (EPS files) and Tables, in order to avoid file transfer time-out problem due to slow Internet speed.    

Type of articles

Regular research articles should be limited to 30 typed pages (double-spaced typing throughout), and should contain no more than 8 Figures and/or Tables. Titles, headings, and subheadings should be on separate lines and not underlined or emboldened. SI units of measurement should be used. Manuscripts reporting new compounds should show results on essential spectroscopic characterization and/or elemental analyses. Manuscripts reporting known compounds will only be published if there is interesting new data on their distribution, structure, and/or function. Papers describing biological screening of crude extracts without identification of active principle(s) should not be submitted. When plant constituents have been chemically identified, voucher specimens of the plant used should be deposited in a recognized herbarium and the identification number quoted. Authors may provide supplementary material for reviewing, e.g. extensive experimental data, graphical or spectral data, which cannot be included in the paper due to space limitations.

Short reports have similar subject scope to the regular research article, except that they are relatively short and hence do not merit a full-length regular research paper. Short reports should contain no more than 20 typed pages and have no more than 4 Figures and/or Tables, and are accepted either as short but essentially complete works or as rapid communications. In all cases, authors will be expected to supply high-quality manuscript and expedite any necessary revisions to facilitate rapid publication. Authors must make sure that their manuscript conforms to the correct style of the journal.

A checklist can be downloaded to help prepare the manuscript. Alternatively, the authors can check from a recent issue of the published papers available on-line at the Web site http://www.scienceasia.org.
