1. Single-line-to-earth fault limitation through the setting of Petersen coil in power transformer neutral / Limitação de correntes de falta fase-terra por meio do ajuste de bobina de petersen em neutro de transformadores de potência
The Petersen coil insertion on the neutral of the electrical distribution power system transformers has been a technical strategy adopted for several electrical utilities, in many countries with the purpose to reduce the earth-fault current intensities, enabling circuit disconnect decrease for intermittent faults and so to improve the electrical power qualit

2. Comportamento de transformadores de corrente sob condições de energização de um transformador de potência
The objective of this dissertation consists in the study of the neutral current on the connection of current transformers when in secondary, shows or not an unbalanced level during the process of energization in a power transformer. These currents according to the test realized in the laboratory can cause disconnection and interruption, causing big damages.

3. Molecular Population Genetics of Sex Determination Genes: The Transformer Gene of Drosophila Melanogaster
The transformer locus (tra) produces an RNA processing protein that alternatively splices the doublesex pre-mRNA in the sex determination hierarchy of Drosophila melanogaster. Comparisons of the tra coding region among Drosophila species have revealed an unusually high degree of divergence in synonymous and nonsynonymous sites. In this study, we tested the h
