Building such a wall could cost as much as $8 billion, and even if it were able to be built legally (current international and environmental law raises question about that), it is unlikely to be truly effective, given that passage between the two countries also occurs by sea and air, that drones are being used with increasing frequency, and that tunnels can be built to bypass the border.
That passage between Elena and Sonia, for instance, famously concludes with Sonia returning to tell Elena that Serebryakov has forbidden her to play the piano — a dousing of spontaneous pleasure that can be heartbreaking.
Darwin, however, added to his images a dotted line representing the crucial dimension of time, scribbling, "The tree of life should perhaps be called coral of life, base of branches dead; so that passages [between species] cannot be seen" (90).
In this work, we will take advantage of the fact that MMO dynamics can reproduce the features of the individual calcium oscillations and that the passage between different types of MMOs can be easily controlled, especially in systems where MMOs arise via the mechanism of slow passage through a canard explosion [22, 23].
The children are young enough so that the passage between their two bedrooms is still umbilical, a door through which writer travels nightly once or twice, between midnight and dawn, sometimes more often.
It has been argued that passage through dynamic environments between and within hosts selects for highly mutable loci, or contingency genes [38], [39].
In more severe cases, the cerebrospinal fluid becomes so thickened by pus that the passages between the ventricles (cavities) of the brain and the spaces in the spinal meninges become blocked, causing fluid to accumulate.
Interesting protrusions were observed that narrowed the passage between the chambers made by the O-layer and I-layer, forming a middle platform.
And gates that allow passage between the neighborhoods are still sealed at certain hours.
Air lock, device that permits passage between regions of differing air pressures, most often used for passage between atmospheric pressure and chambers in which the air is compressed, such as pneumatic caissons and underwater tunnels.
The addition would run from Greenfield, Massachusetts, to Troy, New York, and it required tunnelling through Hoosac Mountain, a massive impediment, nearly five miles thick, that blocked passage between the Deerfield Valley and a tributary of the Hudson.
