Carbon export from mangrove forests to the oceans partly acts as a sink for atmospheric CO2, exceeding the rate of carbon burial in mangrove soils. Primary production in ecosystems adjacent to mangroves may prevent degassing and enhance further carbo

In hydrodynamic models, vegetation is commonly approximated as an array of vertical cylinders to represent its impacts on flow and sediment transport. However, this simple approximation may not be valid in the case of Rhizophora mangroves that have c

This paper proposes and analyzes an active-shielding method to reduce EMF of wireless power transfer (WPT) systems. Additional power supplies and two windings cancel magnetic field generated by the WPT coils with only reactive power. The advantage of
