\section*{Introduction}
The Introduction section must identify the nature of the problem under investigation in relation to its antecedents, in a clear and summarized way, while utilizing relevant references. An introduction that consists of an extended literature review is not acceptable.
Types of Articles:
{\begin{enumerate}
\item \textbf{original articles: maximum 15 (fifteen) pages};
\item \textbf{review articles: maximum 20 (twenty) pages};
\end{enumerate}}
\section*{Materials and methods}
The section Material and methods can precede or follow the section Results and discussion, but they must be separated.
\section*{Results and discussion}
\begin{enumerate}
\item Figures and Subtitles:
\begin{itemize}
\item Include figures in the text with titles and subtitles, following their appearance order.
\item Explicitly reference each figure in numerical order (e.g., Figure 1, Figure 2(a), Figure 2(b), etc.).
\item Place the figure title on top of the figure.
\item Subtitles should be concise, preferably appearing in a box on the figure or in the title.
\end{itemize}
\item File Format for Illustrations:
\begin{itemize}
\item Provide a .zip or .tar file containing high-definition (.png format, minimum 300 dpi) illustrations.
\item Name individual files in the order they appear in the text (e.g., Fig1.png, Fig2.png).
\end{itemize}
\item Copyrighted Material:
\begin{itemize}
\item If using copyrighted material, obtain written permission from the owners to reproduce the illustrations.
\item Clearly indicate the source of the illustration and include the phrase "Reproduced from..." in the illustration.
\end{itemize}
\item Tables:
\begin{itemize}
\item Include tables in the text with explanatory titles for the presented data.
\item Reference each table in numerical order (e.g., Table 1, Table 2).

\end{center}
\end{table}
\end{itemize}
\vspace{1cm}
\item Algorithms:
\begin{itemize}
\item Present algorithms as text, without enclosing them in boxes.
\end{itemize}
\item Math and Equations:
\begin{itemize}
\item Prevent confusion between similar characters (e.g., "l" and "1").
\item Ensure clarity in character placement for superscripts and subscripts.
\item Use consistent superscript notation for exponential expressions (e.g., 5x10$^3$ instead of 5E03).
\item Represent vectors and matrices in bold.
\item The equations are listed sequentially in the text, with right-hand numbering, for example,
\begin{equation}
\label{eq1}
\rho_i=\frac{\sum^{k}_{j=1} d_{i,j}}{(k^2-1)}.
\end{equation}
In equation \eqref{eq1}, ...
\end{itemize}
\item The journal \textbf{Semina: Exact and Technological Sciences} from 2023 on utilizes the normative instructions from the American Psychological Association (APA Style - \textcolor{blue}{\href{https://apastyle.apa.org/}{LINK}}) for articles. Check out the Booklet of the Central Library of UEL - \textcolor{blue}{\href{https://sites.uel.br/bibliotecas/wp-content/uploads/2022/03/APOSTILAESTILOAPA.pdf}{LINK}}.
\textbf{Exemples:}

\end{enumerate}
\subsection*{Conclusions}
The Conclusions section, which summarizes the main conclusions of the work, must be presented immediately after the section Results and Discussion.
\subsection*{Author contributions}
The journal \textbf{Semina: Exact and Technological Sciences} from 2023 on adopted the system of taxonomy papers for CRediT contributors. \textcolor{blue}{\href{https://ojs.uel.br/revistas/uel/index.php/semexatas/form}{CRediT}} is a taxonomy of 14 papers that describe the authorial contribution in the making of academic productions. Therefore, all manuscripts submitted to the journal must describe the participation of its authors through a form (\textcolor{blue}{\href{https://ojs.uel.br/revistas/uel/index.php/semexatas/form}{LINK}})
