Due to a fluctuating water table caused by a deluge of irrigation return water and high evapotranspiration rates coupled with low precipitation, capillary migration is the dominant mechanism driving the distribution and accumulation of salts and soluble Se in the upper horizons (Byz) of the wetlands soil.
teeth are relatively abundant in Quaternary deposits from Eurasia and North America, and their isotopic compositions can be used to reconstruct past seasonal patterns in precipitation, diet, and migration.
Assumptions: (1) Homogeneous reservoir distributes and sulfur of precipitation is not migration in reservoir; (2) Water drives gas follows piston displacement; (3) Constant gas water viscosity and deviation factor; (4) Ignore capillary force, gravity, reservoir anisotropy and stress sensitivity, slippage, and skin factor effects during the displacement process; .
In particular, we investigated (1) the use of terrestrial habitats by non-migrating adults in relation to season, breeding chronology, and precipitation, and (2) adult migration behavior, including seasonal timing, duration, distances traveled, and the use of corridors.
The horizon develops over centuries as percolating water from ample, but seasonal, precipitation facilitates the translocation (migration) of material from upper horizons.
The CNT nanobundle grew continuously with repeated CNT migration and precipitation (Fig. 4c).
It was also found that two distinct brine flux patterns occurred; under low-k conditions the brine flux was outward and parallel to CO2 migration and precipitation became limited.
Various theories have been proposed for qualitatively explaining the mechanism of nanoparticles action, including mainly (a) gasification of polymer and precipitation of nanoparticles, (b) migration of nanoparticles towards the surface and (c) nanoconfinement.
The researchers then compared the timing of the extinctions with changes in climate and precipitation, and with human migration.
RNA was extracted from the other 250 µl by phenol chloroform extraction and ethanol precipitation and analyzed by migration on a 1% agarose gel.
