If the alarm indicates a hawk diving toward the colony, all the prairie dogs in its flight path dive into their holes, while those outside the flight path stand and watch.

If a cinematographer shoots a person diving into a pool at 96 frames per second, and that image is played back at 24 frames per second, the presentation will take 4 times as long as the actual event.

If prey manages to escape the diving birds at first, they may give chase using their legs and wings for underwater swimming.

If a diver accidentally breaks off a stalactite from the ceiling or other speleothem formation, it will not reform as long as the cave is underwater so active cave conservation diving techniques are paramount.

If several people are compressor diving from the same boat, several line tenders are needed in the boat to stop the airlines from getting tangled and kinked and so blocked.

If the indicating needle of the contents gauge vibrates when the diver inhales that may indicate the diving cylinder pillar valve is only partially open and will not provide enough gas at the higher ambient pressures at depth.

If a waster is used, the boat at the surface can be used to break the waster at the end of diving before the shot is lifted.

If the main line is attached to the dive site, the divers must untie it before ascending at the end of diving otherwise they lose their shot.

If the diver is to be working at extreme depths for a long period, the diver may live in a special underwater habitat called a diving chamber.

If the pilot is not proficient in the use of gyroscopic flight instruments, these errors will build up to a point that control of the aircraft is lost, usually in a steep, diving turn known as a graveyard spiral.

If the runner is tagged out while diving back to the base, it is called a pickoff.

: If, in page after page of The Fountainhead and Atlas Shrugged, you show someone being heroic by ruthlessly setting feelings aside, and if you show someone being rotten and depraved by, in effect, diving headlong into his feelings and emotions, and if that is one of your dominant methods of characterization, repeated again and again, then it doesn't matter what you profess, in abstract philosophy, about the relationship of reason and emotion.

If the diagnosis of decompression illness is considered questionable, the diving officer may order a test of pressure.

If unavoidable, wearing a hat or waving hands in the air should prevent contact from being made but will not prevent the diving behavior.

If the casualty is not capable of making an ascent, due to injury or unconsciousness, or the casualty cannot make a safe and controlled ascent, perhaps due to the loss or damage of the diving mask, the rescuer must control the casualty's ascent.

If a diving injury such as decompression sickness is suspected, the success of recompression therapy as well as a decrease in the number of recompression treatments required has been shown if first aid oxygen is given within four hours after surfacing.

If, for example the other buddy partner has lesser skills or experience, a divers own self sufficiency skills diminishes the need for that less experienced partner to become engaged in some procedure for which they are not fully capable, thereby providing a situation of improved safety for both diving partners.

If there is a significant ( greater than 10 %) difference between cylinders, that may be an indication that valves or cylinder head gaskets are leaking, piston rings are worn or that the block is cracked.

If, however, the cylinders are at some angle to one another, then there is a large volume surrounding the cylinder which the approaching cylinder's center-of-mass cannot enter ( due to the hard-rod repulsion between the two idealized objects ).

If these extra cylinders are small, they are sometimes called " pony cylinders ".

If comparable bore to stroke ratios are employed, an engine with more cylinders will have a greater piston area and a shorter stroke.

If an even number of cylinders was used, the equally timed firing cycle would not be feasible.

If we assume an even firing engine, we can divide 720 degrees by the number of cylinders to determine how often a power stroke occurs.

If the bore is 10 cm and the stroke is 5 cm with four cylinders, the calculation is:

If Leeds really did resume cylinder production in 1905, the cylinders would have to have been molded black waxes or they would not have survived on the market if they were brown.

If these return the same geometry, it should be safe to use Gparted, so long as it is set to round to cylinders, and you only add partitions to the end of the partition table.

If aerosol cans were simply filled with compressed gas, it would either need to be at a dangerously high pressure and require special pressure vessel design ( like in gas cylinders ), or the amount of gas in the can would be small, and would rapidly deplete.

If the assumption that M and N are simply connected is dropped, h-cobordisms need not be cylinders ; the obstruction is exactly the Whitehead torsion τ ( W, M ) of the inclusion.

If higher ratios are used, higher pressures and temperatures are observed in the cylinders.

If the crankshaft on one bank of cylinders is made to rotate in the opposite direction of the crankshaft on the other bank, then the gyroscopic effects of the rotating components would be canceled.

If two equal cylinders are pressed together then the contact area is flat.

If the coils become damaged they may still operate at low engine rpm normally, but at higher engine loads the coils can break down resulting in engine power loss as the number of power producing cylinders reduce from six to four or even in worse case scenarios two.

If the two cylinders rotate in opposite sense then spiral vortex flow arises.

If it were not for an old professor who made me read the classics I would have been stymied on what to do, and now I understand why they are classics ; ;

If I even hint at it do you think it will matter that you are his nephew -- and not even a blood nephew ''??

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 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 to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

If Jews are identified as a religious body in a controversy that comes before a national or international tribunal, it is obviously compatible with the goal of human dignity to protect freedom of worship.

If they are right, they will prevail of and by themselves.

Without preliminaries, Esther asked him, `` If you are a world citizen, will you take Garry Davis' place in his tent while he goes to the hospital ''??

If we are to believe the list of titles printed in Malraux's latest book, La Metamorphose Des Dieux, Vol. 1 ( ( 1957 ), he is still engaged in writing a large novel under his original title.

If the would-be joiner asks these questions he is not likely to be duped by extremists who are seeking to capitalize on the confusions and the patriotic apprehensions of Americans in a troubled time.

If we break the minister to our bit, we are buying back our own sins.

If the record buyer's tastes are somewhat eclectic or even the slightest bit esoteric, he will find them satisfied on educational records.

If Daddy's books are out of bounds his own picture books are not.

If it will simply delay the debates until the qualifications are closed next spring, and then carry all the candidates on a tour of debates, it can provide a service to the state.

If they are to be commended for foresight in their planning, what then is the judgment of a town council that compounds this problem during the planning stage??

If the Communists are sincere in wanting a united, neutral and disarmed Germany, it might well be advantageous for the German people in this nuclear age.

If only this could be done more often -- with such heartening results -- many of the earth's `` big problems '' would shrink to the insignificances they really are.

If any are left, presently, we may expect to see signs specifically prohibiting the feeding of them too.

If the raw population figures are crucially relevant, then it is idle to think of liberation, as idle as to suppose that Poland might liberate Russia.

If it is not enough that all of our internationalist One Worlders are advocating that we join this market, I refer you to an article in the New York Times' magazine section ( Nov. 12, 1961 ), by Mr. Eric Johnston, entitled `` We Must Join The Common Market ''.

If the UN troops are not mercenaries then the Hessians were not mercenaries either.
