Within each supporting beam, an irrigation channel and a narrow trough were installed.
Water is pumped from the pond to a series of runnels, where it runs back down the slope, through leaves and ferns, to a narrow trough that splashes back down.
The valley itself is a long and narrow trough, averaging about 6 miles (10 km) in width but becoming narrower in some places e.g., at each end of the Sea of Galilee.
The best thing here, sculpturally speaking, runs through the middle of "Untitled (The Fridges)." It's a narrow trough cut into the cement floor and filled with black asphalt.
One is that some NWs begin to break and the fragments shrink into wider and higher elongated islands or 3D islands, leaving a narrow trough on the surface, as indicated by the label 'A'.
H3K4me3 enrichment was observed in close proximity to the transcriptional start sites (TSS) and characterized by a narrow trough roughly at the TSS with highest enrichment levels localized to either side.
GC3s is relatively low at the telomeres (∼45%), increases gradually toward the center of the chromosomes reaching peaks of ∼70%, and then plunges to a narrow trough of ∼40%.
Second, structural modeling suggested that the A−11 t) purine base present in the synthetic promoter construct may be too bulky to stack on Y217, which sits at the bottom of a narrow trough in the σ 2 A structure.
Even more far-out looking are so-called Nazca line drawings in Peru, often huge images formed from narrow troughs incised into the ground.
