Field Test on Buoyancy Variation of a Subsea Bottom-Supported Foundation Model
Journal of Marine Science and Engineering, 2019 The bottom-supported foundation is the most important component of offshore platforms, as it provides the major support to the upper structure. The buoyancy of the bottom-supported foundation is a critical issue in platform design because it counteracts ...

Galilean Hydrostatic Paradox and Archimedes Law
, 2009 A pedagogia tradicional tem subestimado a presença de certos mistérios e paradoxos no ensino da Física. Abordagens indutivistas ingênuas na educação em ciência têm também contribuído para que alguns importantes pressupostos teóricos sejam usualmente ignorados. Uma análise histórica, conceitual e experimental do desenvolvimento da Física pode contribuir
