Welcome to Poraquê, the Institutional Repository (IR) of the Federal University of Western Pará (Ufopa). Our goal is to store, preserve, give access and visibility to the university's scientific production in digital format. The name Poraquê is an allusion to the electric fish of the Amazon, in which your body is capable of producing electrical pulses, it is said, that seeing in the dark, therefore, has energetic autonomy, capable of lighting a lamp.
