This paper presents an Experimental Program developed to identify, describe and differentiate the production traces from use-wear traces on bone artifacts, through the application of functional analysis framework. For this ...

El process tracing es un método para arribar a inferencias causales sólidas. Preocupados por la fragmentación creciente de la literatura en torno a variantes de process tracing, ponemos de relieve aquello que unifica el ...

Trace metal contamination is among the major concerns of stakeholders due to its potential adverse effects on biota and humans, even at low concentrations. Few studies have recently focused on the ability of organisms to ...

In the present study Cathorops spixii, was evaluated as a bioindicator fish for trace metal pollution. Concentrations of cobalt (Co), iron (Fe), selenium (Se) and zinc (Zn) were determined by Instrumental Neutron Activation ...

The levels of six trace metals (Hg, Se, Pb, Cu, Fe, and Zn) were measured in the hair of California sea lion pups from eight rookeries in the Gulf of California, with the aim of relating these levels with the animals feeding ...
