...) , where SDM and other sulfonamides actually sorbed more to sand than to three other soils investigated. A similar phenomenon to the sorption in silica sand was illustrated in the incompatibilities of silica glassware with these antimicrobials, where there was an affinity to the silica active sites...

... are not interacting with single grains. The large interconnected macropores developed in aggregated soils could allow the rapid transport of microbes with little straining. Therefore, the effect of soil aggregation and macropores on straining is unknown, especially for clayey soils, which naturally develop cracks...

The initial 87 Sr/ 86 Sr ratios (0.70435–0.70686) and Sm-Nd model ages (T DM ) (1.0–1.6 Ga) for the Cozahuico Granite and leucosome indicate a magmatic mixture that originated from melted Proterozoic crust...

Pollen analysis of the clastic series indicates an age between upper Aptian—middle Albian, which allows an assignment of this stratigraphic unit to the Nograro Formation. Chemical analysis indicates that the amber has high maturity, which reflects its Cretaceous age...
