Partindo do estabelecimento do sistema consonantal do português, em termos diassistemáticos, este artigo procura examinar os subsistemas brasileiro e português de acordo com as correlações e relações de simetria que neles ocorrem. Como resultado, constata que o sistema consonantal português se caracteriza por uma localização central avançada com predominância do traço [ + agudo ].

In this work we make an introduction to Lattice Gauge Theory, focusing on the Elitzur Theorem about the expected value of not gauge invariant local observables. Finally, after the exposure of the main facts of the theory, we make an extension to semilocal models

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.
