To address this issue, we examine the effect of volatiles on melting to determine if regions of low seismic velocities may also be interpreted as regions of melting wit...

OBJECTIVE The aim of this study was to evaluate the effect of the addition of metallic ions to carbonated drinks on their erosive potential.
