It is our pleasure to present the set of texts of the second issue of Education and Research in 2014. A little dossier of texts on a current theme opens this issue. We hope that theme will gain ground in the reflections of Latin American scientific community. The editorial board of our journal has long cherished the idea of promoting a quality debate which could help publishers of Brazilian jou...

State-selected ion-molecule reactions: Charge transfer and atomic rearrangement processes in thermal energy collisions of H2+ (X;v)+N2 and of N2+ (X,A;v) + H2

Anterior N2

Event-related brain potentials (ERPs) in response to novel pictures and subsequent visual exploration were examined. Eighteen undergraduates viewed 120 novel drawings as long as they wished. ERPs were calculated separately for drawings that were viewed longer or shorter than the median viewing time of each participant. The drawings viewed longer elicited a larger anterior negativity (N2) peakin...

A library of 211 echelle spectra taken with ELODIE at the Observatoire de Haute-Provence is presented. It provides a set of spectroscopic standards covering the full range of gravities and metallicities in the effective temperature interval [4000 K, 6300 K]. The spectra are straightened, wavelength calibrated, cleaned of cosmic ray hits, bad pixels and telluric lines. They cover the spectral ra...

Based on the photometric survey of the inner region of the Centaurus cluster (Jerjen & Dressler 1997a) we measured redshifts for a deep, surface brightness limited sample of galaxies using the MEFOS multifibre spectrograph at the ESO 3.6m telescope. With the new data set radial velocities for 120 centrally located cluster members become available which is equivalent to 78% of all known cluster ...
