ESR dating at K and X band of northeastern Brazilian megafauna
Applied Radiation and Isotopes, 2005The archaeological dose (AD) was measured in three tooth samples of giant mammals that belonged to Brazilian megafauna using electron spin resonance (ESR) spectroscopy at X-band (nu approximately 9.5 GHz) and K-band (nu approximately 24 GHz). Samples were collected in Lagoa de Dentro, Puxinanã city in Paraiba, a northeast state in Brazil and were ...

Alternative oilseeds for Northeastern Brazil: unrevealed potential of Brazilian biodiversity
Brazilian Journal of Botany, 2015As of 2014, Brazilian legislation requires the share of diesel substituted by biodiesel to be raised from 5 to 7 %. However, throughout the last years, Northeastern Brazil has only been able to supply roughly 50 % of what was legally required. There seems to be no perspective to increase this proportion without developing new oilseeds adapted to the ...
