The following year he went to Italy, where his observations of the volcano Vesuvius first brought to his attention possible flaws in Werner's Neptunism, the theory that all rocks are formed by sedimentation (settling out at the bottom of the sea).
This layered structure is called cumulate, meaning that the layers (which measure up to several metres thick) result from the sedimentation of minerals out of the liquid magma.
The model was successfully calibrated and validated using sedimentation measurements carried out at different floodplain sections along the river Rhine in The Netherlands during floods.
To determine the oligomeric state of [2Fe-2S] NsrR we carried out sedimentation equilibrium experiments at three different speeds using excess NsrR incubated with 30 bp double-stranded oligonucleotide probes carrying either the hmpA1 or hmpA2 NsrR binding sites.
Sucrose gradient sedimentation was carried out as previously described (Sanford et al, 2004) with minor modification.
Sucrose density gradient sedimentation of dynein complex was carried out as described [20] with some modifications.
Svedberg found that the size and weight of the particles determined their rate of settling out, or sedimentation, and he used this fact to measure their size.
Two sets of dynamic sedimentation tests were carried out using a water elutriation apparatus.
CSW is the dewatered solid residues deposited in the sedimentation tank after washing out over-ordered/rejected fresh concrete and concrete trucks in concrete batching plants.
Quantitative measurements of the Stx B-pentamer stability in solution were carried out through sedimentation equilibrium AUC experiments.
