Sentence examples for physical fractionation from inspiring English sources

Organic matter in free and intra-aggregate light fractions (FLF and IALF) was extracted by physical fractionation.

Physical fractionation, in contrast to chemical fractionation, allows for isolation of fractions, can isolate as intact as possible the SOC associated predominantly with soil minerals (primary organo-mineral complexes) and also the SOC protected within aggregates (secondary organo-mineral complexes) due to their three-dimensional architecture (Straathof et al. 2014).

This step occurs in the periplasm [37], but our results are not in disagreement with this because the physical fractionation methods used do not allow to distinguish periplasmic and cytosoluble fractions in Brucella.

In this study the physical fractionation based on particle size of organic matter was used as opposed to the conventional KMnO4.

Physical fractionation revealed large quantities of particulate organic matter (POM, i.e. labile SOC) for all samples, suggesting an overall high vulnerability of mountain SOC stocks to environmental changes.

Physical fractionation of soil according to particle size followed by chemical, biological, and physical analyses of fractions is a powerful tool in process-oriented SOM research (Mao et al. 2007).

Stocks of SOC in the top 15 cm of the grassland soils were determined from bulk soil samples and in soil fractions after a combination of physical and chemical fractionation.

The various isotopes of Pb provide an ideal tool for characterizing the original source of heavy metal pollution because the isotopic ratios are not measurably influenced by physical or chemical fractionation processes.

Physical and chemical fractionation will greatly assist in these studies; further miniaturisation will enhance separation capacity and thereby improve the resolution of the analytical voxel space (Figs.  5 and 12).

All the coated HA showed higher sorption to NOR and OFL in comparison to the original HA, suggesting HA fractionation and/or physical re-conformation during organo-mineral complex formation.

Soil analyses carried out were: macro- and micromorphological, physical, chemical, mineralogical, C isotope fractionation, and OSL dating analyses.
