This is because electricity networks were designed for power to flow in a single direction, from a large power station to homes and businesses.
Phalaenopsis orchids, sometimes called moth orchids, are monopodial types, so-called because they grow upward in a single direction from a single stem, with flowers emerging from between the leaves.
In the 19th and 20th centuries, some scientists endorsed this originally religious understanding of time as developing in a single direction from a finite starting-point towards a final end.
"Most of the 3D printers out there allow a single direction: from a digital model to a printed part," explains one of FABtotum's two creators, Marco Rizzuto.
Information processing that proceeds in a single direction from sensory input, through perceptual analysis, towards motor output, without involving feedback information flowing backwards from 'higher' centres to 'lower' centres.
Then, in the nineteen-sixties, Howard Temin, a virologist at the University of Wisconsin, began to question the "central dogma" of molecular biology, which stated that genetic instructions moved in a single direction, from the basic blueprints contained within our DNA to RNA, which translates those blueprints and uses them to build proteins.
Eventually, Obama came to see the church as a "redistributor of values," helping congregants like him to navigate tricky social and economic divisions: Only now the redistribution didn't run in just a single direction from the schoolteacher or the physician who saw it as a Christian duty to help the sharecropper or the young man fresh from the South adapt to big-city life.
In most case, it would take about 1-2 s for resizing an image in a single direction from 200 × 133 to 100 × 133, and about 10-40 s from 500 × 332 to 250 × 332. Figure 8 shows resizing results with several methods.
Examples of resizing the image in a single direction, from the size 200 × 133 to 112 × 133, are shown in Figure 5. Experiments show that, for most distributed and concentrative images, salient objects and important regions can be preserved well by our method.
When the trend forms by competition, the ancestral form will persist and force selection in a single direction, away from the ancestral species.
Firstly, if it is assumed that the fractures are formed by deposit extension and thus that the deposit footprint has increased, then lo can be found by subtracting the sum of fracture widths (along a single direction, x) from the present day deposit dimension, l X along the same direction (thus l X = l l t ).
