Joaquim da Costa Ribeiro
Joaquim da Costa Ribeiro, Brazilian physicist (Rio de Janeiro 08 July 1906 – Rio de Janeiro 29 July 1960) ACHIEVEMENTS Discovered thermo-dielectric effect or Costa Ribeiro effect in 1944. The discovery was presented in session of 14 November 1944 at Brazilian Academy of Sciences and published in On the thermo-dielectric effect. Anais Acad. Bras. Ciencias 22(3):325-348, 1950.
