If the Republicans and Southern Democrats join to defeat medical care for the old under the Social Security program, they will thereby erect still another barrier to GOP hopes in the cities.

If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured.

If the ion energy is sufficiently high ( usually tens of MeV ) to overcome the coulomb barrier, there can even be a small amount of nuclear transmutation.

If an electron of energy E is incident upon an energy barrier of height U ( z ), the electron wave function is a traveling wave solution,

# If all the particles are identical ( same energy barrier and same magnetic moment ), their easy axes are all oriented parallel to the applied field and the temperature is low enough ( T < sub > B </ sub > < T ≲ KV /( 10 k < sub > B </ sub >)), then the magnetization of the assembly is.

If they have nearly enough energy, they can tunnel through the remaining barrier.

If the electron does not have enough energy to surpass the potential barrier, then it is forced away by the electrostatic force, described by Coulombs Law, associated with the electric potential barrier.

If the land subsides slowly, the fringing reefs keep pace by growing upwards on a base of older, dead coral, forming a barrier reef enclosing a lagoon between the reef and the land.

* If the barrier is broken there is a 10-second penalty

If they break through another barrier they become leaders, and once they have contributed to the community for some time they become elders.

If one inserts a more realistic barrier model into the simplest form of the Schrödinger equation, then an awkward mathematical problem arises over the resulting differential equation: it is known to be mathematically impossible in principle to solve this equation exactly in terms of the usual functions of mathematical physics, or in any simple way.

If sea level changes are too drastic, there will not be enough time for wave action to accumulate sand into a dune, which will eventually become a barrier island through aggradation.

If the Weismann barrier is permeable, then genetic treatments of somatic cells may actually result in a heritable change to the genome, possibly resulting in the genetic engineering of the human species rather than just individuals.

If an isolated system is left long enough, it will reach a state of thermal equilibrium, in which its temperature will be uniform throughout, but not necessarily a state of thermodynamic equilibrium, if there is some structural barrier that can prevent some possible processes in the system from reaching equilibrium.

If there is an intact blood – brain barrier, osmotherapy may be carried out by administering IV mannitol to create a hypertonic solution within the blood to draw water out of the neurons.

If the ticket has not been paid for, the boom barrier will not raise and will force the customer to either press the intercom and speak to a staff member, or reverse out to pay at the pay station or cashier booth.

If a ticket has not been paid, the barrier will not raise.

If, however, the porous barrier is selective to which ions are let through, then diffusion alone will not determine the resulting solution.

If unrecognized, the condition leads to liver failure -- but not kernicterus, as the liver is still able to conjugate bilirubin, and conjugated bilirubin is unable to cross the blood – brain barrier.

If an air space is not present or is too small, heat may be able to conduct through the radiant barrier.

If shoulder subluxation occurs it can become a barrier to the rehabilitation process.

If the driver launched the car with too much power for the available traction, he will have wheelspin and correspondingly will have a longer time to cross the 60 foot barrier if he were to drive with more finesse.

If you exited before the main barrier or entered beyond it, you would need to pass a small row of automated, ungated toll collectors where you are supposed to pay the reduced toll.

If, when this was all over, she found the words to tell him about it, she wondered if he would ever understand.

If you don't leave this country within 3 days, your life will be taken the same as Powell's was.

If we was both armed, you wouldn't talk so tough ''.

If it were the enemy, tactically his position was correct.

If the turn was too tight, a barrel roll would bring them out.

If it were not that I knew who it was I could have mistaken it for my Aunt so well did her clothes fit him.

If Franklin was an authentic genius, then Alexander Hamilton, with his exceptional precocity, consuming energy, and high ambition, was a political prodigy.

`` If you can conveniently let me have twenty dollars '', he wrote one friend in 1791 when he was Secretary of the Treasury.

If an automobile were approaching him, he would know what was required of him, even though he might not be able to act quickly enough.

If living Jews were unavailable for study, the Bible was at hand.

If there was ever a thought in her mind she might devote her life to religion, it was now dispelled.

If his scholarship and formal musicianship were not all they might have been, Mercer demonstrated at an early age that he was gifted with a remarkable ear for rhythm and dialect.

If she were not at home, Mama would see to it that a fresh white rose was there.

If, as Reid says, `` nearly all his poetry was produced when he was not taking opium '', there may be some reason to doubt that he was under its influence in the period from 1896 to 1900 when he was writing the poems to Katie King and making plans for another book of verse.

If Robinson was a liar and a slanderer, he was also a very canny gentleman, for nothing that Pike could do would pry so much as a single word out of him.

If his circumspection in regard to Philip's sensibilities went so far that he even refused to grant a dispensation for the marriage of Amadee's daughter, Agnes, to the son of the dauphin of Vienne -- a truly peacemaking move according to thirteenth-century ideas, for Savoy and Dauphine were as usual fighting on opposite sides -- for fear that he might seem to be favoring the anti-French coalition, he would certainly never take the far more drastic step of ordering the return of Gascony to Edward, even though, as he admitted to the English ambassadors, he had been advised that the original cession was invalid.

If the historian was convinced of his own correctness, then he should not allow his vision to become fogged by disturbing facts.
