Cotton boomed, but over time overwatering and leaks left farmland too salty to support crops, and the river water, used and reused on its way downstream, became ever saltier and more laced with pesticides.
The velocity profile downstream becomes stable after a distance of about 5D.
With the particles blocked by the fences, the channel downstream became erosive, because it was devoid of large particles that produce substantial hydraulic resistance.
Scores of huge Chinese dams are being developed upriver on the Yangtze beyond Three Gorges, on the heretofore lightly dammed upper Mekong that downstream becomes the fishery and agricultural wellspring of Indochina, and on the upper Brahmaputra, which runs through Tibet before feeding eastern India and Bangladesh.
Using several reporter assays, the authors show that when a premature termination codon (PTC) is present, the region of the ORF downstream becomes accessible to miRNA-mediated repression.
The upstream reaches of the valleys are gravelly and rather dry, while the central and downstream portions become deltaic, wet, and swampy.
One possible explanation is due to differences in the threshold at which downstream genes become effective, underscoring the importance of matching the dynamic range of input/output elements in a circuit (Figure 7).
The interest in any recombination system will increase as more downstream applications become compatible with the system.
As a result, this "dominant active" mutant KRAS and its downstream effectors become independent of epidermal growth factor (EGFR), among others.
If that system of buffering is disrupted by over-expression of AtCHR23, downstream genes become more variable and compromise the expression of other genes in ways that result in the reduced growth phenotype here documented.
