| | | | |
| − | Provide a maximum of 6 keywords, and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field should be used. These keywords will be used for indexing purposes.

| − | An abstract is required for every document; it should succinctly summarize the reason for the work, the main findings, and the conclusions of the study. Abstract is often presented separately from the article, so it must be able to stand alone. For this reason, references and hyperlinks should be avoided. If references are essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself. -->==

| | | | |
| | + | Se presenta el resumen de varios años de investigación sobre el efecto inhibidor de los <math>NO_2</math> en la corrosión de las armaduras. Se ha estudiado su efecto inhibidor mediante el trazado de curvas potenciodinámicas y galvanostáticas y se han medido velocidades de corrosión intantánea usando el método de Resistencia de Polarización. |
| | + | Se ha podido comprobar mediante esta última técnica que, cuando hay Cl presentes desde el momento del amasado, los <math>NO_2</math> inhiben completamente el ataque si se añaden en cantidad suficiente. Cantidades insuficientes de <math>NO_2</math> nunca han provocado mayores ataques en nuestros ensayos, sino que siempre han reducido el área corroída o la intensidad del ataque. |
| | + | Los NO2 son también efectivos en hormigón carbonatado donde, al menos, siempre reducen el ataque cuando no lo inhiben por completo |

| − | Most of the documents in Scipedia are written in English (write your manuscript in American or British English, but not a mixture of these). Anyhow, specific publications in other languages can be published in Scipedia. In any case, the documents published in other languages must have an abstract written in English.

| − | 2.1 Subsections
| + | |
| − | | + | |
| − | Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1, 1.2, etc. and then 1.1.1, 1.1.2, ... Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Capitalize the first word of the headings.

| − | 2.2 General guidelines
| + | |
| − | | + | |
| − | Some general guidelines that should be followed in your manuscripts are:
| + | |
| − | | + | |
| − | * Avoid hyphenation at the end of a line.
| + | |
| − | | + | |
| − | * Symbols denoting vectors and matrices should be indicated in bold type. Scalar variable names should normally be expressed using italics.
| + | |
| − | | + | |
| − | * Use decimal points (not commas); use a space for thousands (10 000 and above).
| + | |
| − | | + | |
| − | * Follow internationally accepted rules and conventions. In particular use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI.
| + | |

| − | | + | |
| − | 2.3 Tables, figures, lists and equations
| + | |
| − | | + | |
| − | Please insert tables as editable text and not as images. Tables should be placed next to the relevant text in the article. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article.
| + | |
| − | | + | |
| − | Graphics may be inserted directly in the document and positioned as they should appear in the final manuscript.
| + | |
| − | | + | |
| − | Number the figures according to their sequence in the text. Ensure that each illustration has a caption. A caption should comprise a brief title. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used. Try to keep the resolution of the figures to a minimum of 300 dpi. If a finer resolution is required, the figure can be inserted as supplementary material
| + | |
| − | | + | |
| − | For tabular summations that do not deserve to be presented as a table, lists are often used. Lists may be either numbered or bulleted. Below you see examples of both.

| − | * A bulleted list item
| + | |
| − | | + | |
| − | * Another one
| + | |
| − | | + | |
| − | You may choose to number equations for easy referencing. In that case they must be numbered consecutively with Arabic numerals in parentheses on the right hand side of the page. Below is an example of formulae that should be referenced as eq. (1].

| − | Supplementary material can be inserted to support and enhance your article. This includes video material, animation sequences, background datasets, computational models, sound clips and more. In order to ensure that your material is directly usable, please provide the files with a preferred maximum size of 50 MB. Please supply a concise and descriptive caption for each file. -->==

| − | ==3 Bibliography<!--
| + | |
| − | Citations in text will follow a citation-sequence system (i.e. sources are numbered by order of reference so that the first reference cited in the document is [1], the second [2], and so on) with the number of the reference in square brackets. Once a source has been cited, the same number is used in all subsequent references. If the numbers are not in a continuous sequence, use commas (with no spaces) between numbers. If you have more than two numbers in a continuous sequence, use the first and last number of the sequence joined by a hyphen

| − | | + | |
| − | You should ensure that all references are cited in the text and that the reference list. References should preferably refer to documents published in Scipedia. Unpublished results should not be included in the reference list, but can be mentioned in the text. The reference data must be updated once publication is ready. Complete bibliographic information for all cited references must be given following the standards in the field (IEEE and ISO 690 standards are recommended). If possible, a hyperlink to the referenced publication should be given. See examples for Scipedia’s articles [1], other publication articles [2], books [3], book chapter [4], conference proceedings [5], and online documents [6], shown in references section below. -->==
