No presente artigo discuto a transexualidade feminina na infância. Utilizo como objeto de análise o filme Minha Vida em Cor-de-Rosa (Bélgica, França, Reino Unido, 1997) e o documentário Meu Eu Secreto (Estados Unidos da América, 2007), procurando fazer um... see more

Resulting from the Industrial Revolution 4.0, English is evolving into a global language and is detected from multi-aspects consisting of technological, scientific, and business aspects, and completely, English language learning quality must be enhanced. ... see more

We investigate an extension of the standard model with vector-like fermions and an extra Abelian gauge symmetry. The particle mass spectrum is calculated explicitly. The Lagrangian terms for all the gauge interactions of leptons and quarks in th... see more

The black TiO2_2 with substantial Ti3+^3+ and oxygen vacancies exhibit an excellent photoelectrochemical water-splitting performance due to the improved charge transport the extended visible light response. In this study, black TiO2_2 nanotube arrays synt... see more

The Lagrangian of a theory possessing two Abelian gauge symmetries may contains a gauge kinetic mixing term without violating any known symmetries. In this paper, the formulation of theories extended by an additional Abelian gauge symmetry in the superfie... see more

The Randall-Sundrum solution to the hierarchy problem in the brane-world scenario has made a significant impact on the development of model building.We investigate in this paper a model of supersymmetry in a 5D spacetime with the Randal-Sundrum warped met... see more
