Amostras de breu de cinco espécies (Protium cf. apiculatum, P. cf. hebetatum, P. cf. heptaphyllum, P. tenuifolium e Trattinnikia peruviana), provenientes da Reserva Biológica Adolfo Ducke (Manaus-AM, Brasil), foram analisadas por FR...

Elemental Analysis of Lubricating Oil Samples Using Edxrf Technique

Evidence for ecological divergence across a mosaic of soil types in an Amazonian tropical tree: Protium subserratum (Burseraceae).

Soil heterogeneity is an important driver of divergent natural selection in plants. Neotropical forests have the highest tree diversity on earth, and frequently, soil specialist congeners are distributed parapatrically. While the role of edaphic heterogeneity in the origin and maintenance of tropical tree diversity is unknown, it has been posited that natural selection across the patchwork of s...

Elemental Analysis of Two Rupee Indian Coins by EDXRF Technique

Energy Dispersive X-Ray Fluorescence (EDXRF) technique has been used to study two Rupee Indian coins minted during the period 1993 to 2010 for their elemental concentrations. From the analysis of the coins, it is found that the coins are made of binary alloy and it was observed that from 2005 onwards, the composition of the coins has been changed from Cupro-Nickel to Ferritic Stainless Steel (F...
