Author Guidelines

1. Submission

All manuscripts should be submitted electronically through RCE site which can be accessed at http://revistas.unitau.br/ojs-2.2/index.php/exatas/. With the submitted manuscript authors should provide the names, addresses and e-mail addresses of four potential reviewers.

Submission of a paper implies that it has not been published previously - also not in any other language-, that it is not under consideration for publication elsewhere, and that if accepted it will not be published elsewhere in the same form, or in any other language, without the written consent of the publisher.


2. Types of Contribution

Papers are published either as a Full Paper or a Review Paper. Comments on these papers are also welcome.

(a) A FULL PAPER is a contribution describing original research, including theoretical exposition, extensive data and in-depth critical evaluation, and is peer reviewed. The total length of a manuscript including figures, tables and references must not exceed 8000 words (40 pages).

(b) REVIEW PAPERS are encouraged, but the Editor-in-Chief must be consulted beforehand, in order to decide if the topic is relevant. Only critical review papers will be considered. The format and length of review papers are more flexible than for a full paper. Review papers are peer reviewed.

(c) COMMENTS on papers already published are welcome, subject to the criteria of interest, originality and the approval of the appropriate Editor. Comments can include extensions to, or criticisms of, those papers. They must provide arguments that are reasoned, and not presented in a confrontational fashion. They will be sent to the author of the original paper for reply, the outcome of which may be publication in a future issue. Comments and Authors' Replies should not exceed 1200 words each and will be received until 4 months after publication. They will be accepted or rejected without corrections.


3. Paper Submission

(a) All types of accepted submissions will have been peer reviewed.

(b) Papers must be in English (preferentially), Portuguese or Spanish.

(c) Manuscripts must be in double-spaced form with wide margins and line numbering. A font size of 12 pt is required. The corresponding author should be identified (include a Fax number and E-mail address). Full postal addresses (including e-mail addresses) must be given for all co-authors. The Editors reserve the right to adjust style to certain standards of uniformity.

(d) Multi-part papers are not to be considered.

(e) Papers that are requested by the editors to be revised must be returned within 4 weeks or they will be regarded as withdrawn.

(f) No page charges apply for Water Research.

(g) The corresponding author, at no cost, will be provided with a PDF file of the article via e-mail. The PDF file is a watermarked version of the published article and includes a cover sheet with the journal cover image and a disclaimer outlining the terms and conditions of use. Additional copies can be ordered at current printing prices.

(h) Submitted papers should be accompanied by a list of 4 potential referees with names and addresses.


4. Content

All pages must be numbered consecutively. Words normally italicised must be typed in italics or underlined. A manuscript would normally include a title, abstract, key words, introduction, materials and methods, results, discussion, conclusions and references.

(a) Title page. The title page must state the names and full addresses of all authors. Telephone, fax and E-mail numbers must also be included for the corresponding author to whom proofs will be sent.

(b) Abstract. Authors are requested to ensure that abstracts for all types of contribution give concise factual information about the objectives of the work, the methods used, the results obtained and the conclusions reached. A suitable length is about 150 words.

(c) Key words. Authors must list immediately below the abstract up to 6 key words (not phrases) that identify the main points in their paper.

(d) Abbreviations and Notations. Nomenclature must be listed at the beginning of the paper and must conform to the system of standard SI units. Acronyms and abbreviations must be spelled out in full at their first occurrence in the text.

(e) Conclusions. Papers must end with a listing of major conclusions, preferably in a list form.

(f) References. References to published literature must be cited in the text as follows:

Li and Gregory (2006) - The date of publication in parentheses after the authors' names. References must be listed together at the end of each paper and must not be given as footnotes. For other than review papers authors should aim to give no more than 20-30 recent, relevant references. They must be listed alphabetically starting with the surname of the first author, ( year ) followed by the title of the referenced paper and the full name of the periodical, as follows:

Li, G. and Gregory, J. (2006) Flocculation and sedimentation of high-turbidity waters. Water Research 25(9), 1137-1143.

It is particularly requested that (i) authors' initials, (ii) the title of the paper, and (iii) the volume, part number and first and last page numbers are given for each reference.

References to books, reports and theses must be cited in the narrative. They must include the author(s), date of publication, title of book, editor(s) name(s) if applicable, page numbers, name of publisher, and place of publication. The abbreviation et al. may be used in the text. However, the names of all authors must be given in the list of references. Personal communications and other unpublished works must be included in the reference list, giving full contact details (name and address of communicator).

Personal communications must be cited in the text as, for example, Champney (2006).

References in languages other than text language must be referred to by an text language translation (with the original language indicated in parentheses).

Citing and listing of web references. As a minimum, the full URL should be given. Any further information, if known (author names, dates, reference to a source publication etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different heading if desired, or can be included in the reference list.

The digital object identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal Physics Letters B):

doi:10.1016/j.physletb.2003.10.071

When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed never to change.

(g) Illustrations and Tables. The total number of all illustrations and tables should not exceed 10. If illustrations need to take up more space than 2 printed pages in Revista Ciencias Exatas (1 page for shorter contributions) the number of words must be reduced accordingly. All illustrations must be clear and of good quality. Scale bars should be used instead of magnifications, as these change if the photograph is reduced. Tables and their headings must be typed on a separate sheet. Type must be clear and even across columns. Particular care must be taken with nomenclature and sub- and superscripts to ensure correct alignment. Horizontal and vertical lines must be inserted to define rows and columns, and column headings must be correctly aligned.

(h) Colour Illustrations. If, together with your accepted article, you submit usable colour figures then RCE will ensure, at no additional charge, that these figures will appear in colour on the web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in colour in the printed version.


5. Proofs

Corrections to proofs must be restricted to printer's errors. Please check proofs carefully before return, because late corrections cannot be guaranteed for inclusion in the printed journal. Authors are particularly requested to return their corrected proofs to RCE as quickly as possible to maintain their place in the printing schedule.


6. Transfer of Copyright

Upon acceptance of an article, authors will be asked to sign a 'Journal Publishing Agreement'. Acceptance of the agreement will ensure the widest possible dissemination of information. An e-mail (or letter) will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.

Subscribers may reproduce tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations.

If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article.
