Gas Chromatography Coupled to High Resolution Time-of-Flight Mass Spectrometry as a High-Throughput Tool for Characterizing Geochemical Biomarkers in Sediments. [PDF]

Int J Anal Chem, 2018
The performance of gas chromatography coupled to high‐resolution time‐of‐flight mass spectrometry (GC‐HRTofMS) for characterizing geochemical biomarkers from sediment samples was evaluated. Two approaches to obtain the geochemical biomarkers were tested: (1) extraction with organic solvent and subsequent derivatization and (2) in‐situ derivatization ...

Assessing Rainfall Erosivity with Artificial Neural Networks for the Ribeira Valley, Brazil

International Journal of Agronomy, Volume 2010, Issue 1, 2010., 2010
Soil loss is one of the main causes of pauperization and alteration of agricultural soil properties. Various empirical models (e.g., USLE) are used to predict soil losses from climate variables which in general have to be derived from spatial interpolation of point measurements. Alternatively, Artificial Neural Networks may be used as a powerful option
