Geodetic observations are affected by the disturbing potential of the luni-solar tide. Among those observations, the value of g obtained from gravimetric survey needs correction by the gravimetric factor. This correction ...

Currently, the emission of carbon dioxide is the main cause of global warming due to greenhouse effect. Researchers around the world have been studying to find viable solutions to the problem. Biochar is among the latest ...

Terrestrial gravity stations have been in operation for several years throughout Brazil. Minimizing geophysical effects on gravimetric observations is a major challenge in the generation of solid Earth tide models. The ...

This paper proposes a response surface methodology to evaluate the influence of the particle size and temperature as variables and their interaction on the sulfation process using two Brazilian limestones, a calcite (ICB) ...

In the Sierra de San Luis, Central Argentina, a belt of small and discontinuous lenses of mafic-ultramafic rocks intrude a polydeformed basement and are thought to be the cause of a local increase of the metamorphic grade ...

The study of biomass is extremely important, aiming to discover the potential of alternative source that are capable of promoting the development of new technologies. The thermal behavior and chemical characteristics of ...
