DISSERTATIONS AND THESES: Preferably not to use it, as it is considered gray literature.

Tables: The formatting of tables must be carried out using the Microsoft Word table functionality, using Times New Roman font, size 10 and single spacing between lines. Each piece of data to be inserted into the table must occupy a specific cell, separated by rows and columns, ensuring that there are no empty cells. The Table title must be at the top.

It is essential that each column of the table is properly identified so that the data can be understood in a clear and organized manner. Internal dashes in tables should be inserted only below and above the header, as well as in the last row of the table, to highlight key information and visually separate different sets of data.

This instruction must be strictly followed to ensure the correct presentation of information and provide an efficient and accurate reading of the data contained in the tables.

Figures: Figures are visual representations, such as tables, graphs, drawings, diagrams, flowcharts and photos. For the identification and reference of these figures in the text, they should be referred to simply as "Figure", followed by the corresponding number (for example, Figure 1, Figure 2, etc.). The title of Figures, including tables, graphs, drawings, diagrams, flowcharts and photos, must be at the bottom.

Charts: They must present textual information, not numeric, and must be delimited by lines on the sides and with internal lines for better organization. When a table is extracted from other publications, it is necessary to provide the appropriate reference.

Graphs: They must be clear and legible. When a graphic was extracted from other publications, it is necessary to provide appropriate reference to the source.

Schematics, drawings, flowcharts: they must be constructed with appropriate tools and presented in a clear and legible manner. When extracted from other publications, it is necessary to provide appropriate reference to the source.

Photos: Photos must be clear and sent in high resolution.
