If ultra-pure products are the goal, then further chemical separation must be applied.

If the liquid and vapor are not evenly distributed across the superficial tower area as it enters the packed bed, the liquid to vapor ratio will not be correct in the packed bed and the required separation will not be achieved.

If the viewing distance is large compared with the separation of the slits ( the far field ), the phase difference can be found using the geometry shown in the figure below right.

If heaven is a state of supernatural happiness and union with God, and hell is understood as a state of torture and separation from God then, in this view, the Limbo of Infants, although technically part of hell ( the outermost part, " limbo " meaning " outer edge " or " hem ") is seen as a sort of intermediate state.

If we suppose the screen is far enough from the slits ( that is, s is large compared to the slit separation d ) then the paths are nearly parallel, and the path difference is simply d sin θ.

If each mass point has the mass, the tension of the string is, the separation between the mass points is and are the offset of these points from their equilibrium points ( i. e. their position on a straight line between the two attachment points of the string ) the vertical component of the force towards point is

If scatterers are arranged symmetrically with a separation d, these spherical waves will be in sync ( add constructively ) only in directions where their path-length difference 2d sin θ equals an integer multiple of the wavelength λ.

If the first officer had stopped making these inputs at any time before the vertical stabilizer separation, the natural stability of the airplane would have returned the sideslip angle to near 0 °, and the accident would have been avoided.

If the signals are close but not exactly on the same frequency the mix will not only include the audio from both carriers but depending on the carrier separation a whistle might be heard as well representing the difference in the carrier frequencies.

If the aircraft carrying the Hiroshima and Nagasaki bombs had been within the intense nuclear radiation zone when the bombs exploded over those cities, then they would have suffered effects from the charge separation ( radial ) EMP.

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.

If any State in the Union will declare that it prefers separation with the first alternative, to a continuance in union without it, I have no hesitation in saying, ' let us separate '.

If the separation were voluntary on the part of the colored people that would be a different thing but for them to accept Jim-Crowism and then work to make the Exposition a success is a thing in which I do not believe .” While Dr. Booker T. 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 the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If it is an honest feeling, then why should she not yield to it??

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.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.
