1. Introduction

This is an example of papers for the “International Journal on Hands-on Science” and HSCI’ conferences or workshops. These guidelines include complete description of the paper style including formatting, fonts, spacing, and related information for producing your proceedings manuscripts. Please follow them carefully and if you have any questions, send it via e-mail to submissions@ijhsci.aect.pt or hsci2003@gmail.com.

2. Paper organization and formatting

All papers should be written in English. Other languages can be accepted (and welcomed) as in the case of IJHSCI, International Journal on Hands-on Science, www.aect.pt/hsci/ij.html, or for some conferences, as stated on their websites, (in any case a translation of the title and of the abstract in English should be provided). There are no size/length limitations. However six pages long is considered to be a suitable length (letters to the editor should be limited to 3 pages at most). The manuscript should be arranged in the following order:
- Main title
- Author(s), affiliation(s), full and e-mail
   addresses
- Abstract
- Keywords
- Main text
- Footnotes
- Acknowledgements
- References
All printed material, including text and figures, must be kept within a print area of 16 cm (6.3") wide by 24.7 (9.7") high. Do not write or print anything outside the print area. Paper size is A4: 21x29.7 cm (8.3x11.7"). Margins (top, bottom, left, right) are 2.5 cm (1"). If paper size is Letter: 21.6x27.9 cm (8.5x11"), margins are: left and right 2.8 cm (1.1"), and top and bottom 1.6 cm (0.63"). All text must be in a two-column format. Columns are to be 7.7 cm (3") wide, with a 0.6 cm (0.24") space between them. Text must be fully justified. Indent each paragraph by 0.5 cm (0.2").

3. Main title

The main title (on the first page) should begin 2.5 cm (1") from the top edge of the page, centered, and in Times 14-point, boldface type. Capitalize the first letter of nouns, pronouns, verbs, adjectives, and adverbs; do not capitalize articles, coordinate conjunctions, or prepositions (unless the title begins with such a word). Leave a blank line after the title.

4. Author name(s) and affiliation(s)

Author names and affiliations are to be centered beneath the title and printed in Times 12-point, non-boldface type. For multiple authors, affiliations are centered below each author name, italicized, not bold. Include also e-mail addresses. Follow the author information by two blank lines before main text.

5. Type-style and fonts

Wherever Times is specified, Times Roman, or Times New Roman may be used. If neither is available on your word processor, please use the font closest in appearance to Times that you have access to. Please avoid using bit-mapped fonts if possible. True-Type 1 fonts are preferred.

6.	First-order headings (may extend to the next line)

For example, “1. Introduction”, should be Times 12-point boldface, initially capitalized, flush left, with one blank line before, and one blank line after. Use a period (“.”) after the heading number, not a colon. For long headings use a hanging indent aligning the text to the right of the heading number as shown above.

6.1. Second-order headings

As in this heading, they should be Times 12-point boldface, initially capitalized, flush left, with one blank line before, and one after. Use a hanging indent for long headings.

6.1.1. Third-order headings 

Third-order headings, as in this paragraph, are discouraged. However, if you must use them, use 12-point Times, boldface, initially capitalized, flush left, with one blank line before, and one after. Use a hanging indent for long headings.

7. Main text

Type your main text in 11-point Times, single-spaced. Do not use double-spacing. All paragraphs should be indented 0.5 cm (0.2"). Be sure your text is fully justified—that is, flush left and flush right. Please do not place any additional blank lines between paragraphs. 

7.1. Figures

All figures are to be included within the text. Figure captions are to be below the figures, in 9-point Helvetica (or a similar sans-serif font), boldface. Initially capitalize only the first word of each figure caption. Figures are to be numbered consecutively with Arabic numerals throughout the paper, for example: “Figure 1. Database contexts”, and are referred to in the text as Fig. 1, Fig 2, etc. 

7.1.1.	Illustrations, photographs and graphs 

Illustrations, photographs and graphs are considered as figures. All graphics should be centered. Your artwork must be in place in the article (preferably printed as part of the text rather than pasted up). If you are using photographs and are able to have halftones made at a print shop, use a 100- or 110-line screen. Supply the best quality photographs and illustrations possible (for files larger than 10Mb please contact the editors first. Penciled lines and very fine lines do not reproduce well. Remember, the quality of the book cannot be better than the originals provided.

Figure 1. Helvetica, 9 points, boldface

High resolution color photos or pictures are welcomed. However it will be printed b/w in the printed version of the journal and of the conferences/workshops proceedings. Videos or computer simulation can be included for the electronics (online) version of the Journal.

7.2. Tables

All tables are to be included within the text. Table titles are to be above the tables, in 9-point Helvetica (or a similar sans-serif font), boldface. Initially capitalize only the first word of each table title. Tables are to be numbered consecutively with Arabic numerals throughout the paper, for example: “Table 1. Input data.” and are referred to in the text as Table 1, Table 2, etc. Column headings should be as brief as possible.

7.3. Equations

Equations should be numbered serially on the right-hand side by Arabic numerals in parentheses, and referred to in the text by citing the equation number.

7.4. Footnotes

Use footnotes sparingly (or not at all!) and place them at the bottom of the column on the page on which they are referenced. Use Times 8-point type, single-spaced. To help your readers, avoid using footnotes altogether and include necessary peripheral observations in the text (within parentheses, if you prefer, as in this sentence).

8. Acknowledgements

Acknowledgements, if necessary, should appear in a separate paragraph preceding the references.

9. References

List and number all bibliographical references, sorted in order of appearance in the main text, in 11-point Times, single-spaced, with a hanging indent, at the end of your paper. When referenced in the text, enclose the citation number in square brackets, for example [1]. Use the style of the references shown below for: authored book [4], edited book [1], journal article [2], paper in conference proceedings [3], web resource [5] (please don’t forget to indicate date of access in square brackets).
