Observations and modeling of slow-sinkingparticles in the twilight zone
(2013-08)
The biological carbon pump (BCP) transfers carbon from the surface ocean into the oceans’interior,mainly in the form of sinking particles with an organic component, and thereby keeps atmospheric CO2atsignificantly lower ...

Evaluation of the radioactive impact of the phosphogypsum wastes used as amendment in agriculture soils
(E. D. P. Sciences, 2005)
Some 3x109 kg of phosphogypsum (PG) wastes are annually generated by two fertiliser-production factories in Huelva (south-western Spain). PG has relatively high concentrations of 226Ra and other radionuclides, with an ...

A comparative evaluation of the CF:CS and CRS models in 210Pb chronological studies applied to hydrographic basins in Brazil
(Elsevier, 2014)
The Constant Flux: Constant Sedimentation (CF:CS) and Constant Rate of Supply (CRS) of unsupported⧸ excess 210Pb models have been applied to a 210Pb data set providing of eighteen sediments profiles sampled at four ...

Application of a liquid scintillation counter to the measurement of tracing radioactivity in experiments on suspended matter uptake in aquatic environments
(E. D. P. Sciences, 2002)
The experiments on the study of the kinetic transfer coefficients of conservative and non-conservative radionuclides, in aquatic environments, need to determine radionuclide activity in large number of samples. Different ...

The radioactivity of thorium incandescent gas lantern mantles
(MDPI, 2021-02-01)
The use of thorium in providing the intense white luminescence emitted from gas mantles, has a history of some 130 years, the initial application pre-dating by several decades large-scale urban electric lighting. ...
