This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...

In face processing tasks, prior presentation of internal facial features, when compared with external ones, facilitates the recognition of subsequently displayed familiar faces. In a previous ERP study (Olivares & Iglesias, 2010) we found a visibly larger N400-like effect when identity mismatch familiar faces were preceded by internal features, as compared to prior presentation of external ones...

Typically, granitic intrusions that document the lengthy and intricate history of magmatic-hydrothermal system are linked to tungsten deposits. Uncertainty persists about genetic relationship between mineralization development. The primary deposit in Dai Tu region, known as Nui Phao deposit, has been subject a petrographical microscopic examination. Tungsten area often occurs association with f...
