THE VALO GRANDE CHANNEL IN THE CANANÉIA-IGUAPE ESTUARY-LAGOON COMPLEX (SP, BRAZIL): ENVIRONMENTAL HISTORY, ECOLOGY, AND FUTURE PERSPECTIVES [PDF]
Ambiente & Sociedade, 2019 Abstract The channel of the Valo Grande (VG) in the Ribeira de Iguape River (São Paulo State, Brazil), inaugurated in 1852, is one of the largest environmental disasters in the Brazilian coast. This article presents a synthesis of the historical, ecological, geographic and sociopolitical dimensions involving the VG.

Coastline changes and sedimentation related with the opening of an artificial channel: the Valo Grande Delta, SE Brazil [PDF]
Anais Da Academia Brasileira De Ciencias, 2014 The role played by human activity in coastline changes indicates a general tendency of retreating coasts, especially deltaic environments, as a result of the recent trend of sea level rise as well as the blockage of the transfer of sediments towards the coast, especially due to the construction of dams.

Effect of Moving the Tip of the Light Curing Unit on the Irradiance Value Delivered. [PDF]
J Esthet Restor DentABSTRACT Objective To determine the effect of differences in the distances and radial positions of the tips of Light‐Curing Units (LCU) on the irradiance values delivered. Materials and Methods Four LCUs—Valo X, Emitter A, CuringPen, and Pinkwave were tested at different distances from the tip (0, 2, 4, 6, 8 mm) and radial displacements (2 and 4 mm ...

Fracture Resistance of Extensively Compromised Anterior Teeth Restored With Fiberglass Posts and Biomimetic Protocols: An In Vitro Study. [PDF]
J Esthet Restor DentABSTRACT Objective Polyethylene fiber (PF) and fiberglass (FG) posts have been recommended for intraradicular anchorage when there is a significant loss of coronal structure. However, few studies have evaluated their performance in anterior teeth combined with direct restorations as an alternative to single crowns.

Gas Chromatography Coupled to High Resolution Time-of-Flight Mass Spectrometry as a High-Throughput Tool for Characterizing Geochemical Biomarkers in Sediments. [PDF]
Int J Anal Chem, 2018 The performance of gas chromatography coupled to high‐resolution time‐of‐flight mass spectrometry (GC‐HRTofMS) for characterizing geochemical biomarkers from sediment samples was evaluated. Two approaches to obtain the geochemical biomarkers were tested: (1) extraction with organic solvent and subsequent derivatization and (2) in‐situ derivatization ...
