The report included much of the same tone and opinions held in the Washington Society address, except that, uncharacteristically for its chief architect, it alluded to the threat of secession saying, " If a separation of the states shall ever take place, it will be, on some occasion, when one portion of the country undertakes to control, to regulate, and to sacrifice the interest of another.

If charge separation is involved, this energy difference can result in an emf.

If the light bulb is removed ( open circuit ) the emf between the electrodes is opposed by the electric field due to charge separation, and the reactions stop.

If no scriptorium was available, then “ separate little rooms were assigned to book copying ; they were situated in such a way that each scribe had to himself a window open to the cloister walk .” The separation of these monks from the rest of the cloister indicates just how revered these monks were within their society.

Washington was invited and attended as a prominent guest, many African Americans attending the exposition resented being forbidden by law to patronize its restaurants ; the exposition enforced Virginia's legal racial segregation and other Jim Crow laws.

If there are N modes locked with a frequency separation Δν, the overall mode-locked bandwidth is NΔν, and the wider this bandwidth, the shorter the pulse duration from the laser.

If we additionally assume that the image plane is perpendicular to the ground plane ( an imaginary plane Tangential to the surface of the Earth ), and that the waterfall flows on a plane that is parallel to the image plane, we can estimate the height by measuring the vertical separation of waterfall head and base in

If this separation is lost, as in a ' frozen shoulder ', the joint cannot move.

If this separation is incomplete, air escapes through the nose, causing speech to be perceived as nasal.

If the process is stationary, it depends on their separation, x-x ', while if non-stationary it depends on the actual position of the points x and x ; an example of a stationary process is the Ornstein – Uhlenbeck process.

`` If you want to see something, he's back on the other side by the trunk of the car ''.

If the Union conceded this to them, the same right must be conceded to each remaining state whenever it saw fit to secede: This would destroy the federal balance between it and the states, and in the end sacrifice to the sovereignty of the states all the liberty the citizens had gained by their Union.

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.
