With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyz...
This text covers the professional and scientific career of Maria Cecilia Ferro Donnangelo, professor, researcher and influential intellectual in the area of Collective Health. Born in 1940, and killed in a car accident in 1983, she actively participated in the emergence of Collective Health in Brazil and greatly influenced the creation of the sub-areas of Social Science and the Humanities in th...
We discuss synthetic receptors for haptic sensing. These are based on magnetic field sensors (Hall effect structures) fabricated using standard CMOS technologies. These receptors, biased with a small permanent magnet can detect the presence of ferro or ferri-magnetic objects in the vicinity of the sensor. They can also detect the magnitude and direction of the magnetic field.
