If several alternatives independently evolved, they all undoubtedly rapidly converged to the TCA cycle.

If we allow to incorporate the algebraic sign, this becomes a sum and implies that there is a function of state which is conserved over a complete cycle.

If is delayed ( time-shifted ) by of its cycle, it becomes:

If the coil is designed to be energized with alternating current ( AC ), a small copper " shading ring " can be crimped to the end of the solenoid, creating a small out-of-phase current which increases the minimum pull on the armature during the AC cycle.

If these genes are not expressed, the cell cycle does not continue, effectively inhibiting cell division.

If the damage can be repaired, the cell cycle can continue.

If proven cost-effective in a life cycle cost analysis during the Analysis of Alternatives ( AoA ) phase of preliminary ship design, new ship classes ( e. g. CG ( X )) could proceed with nuclear propulsion.

If an array is used to represent a cycle, it is convenient to obtain the index with a modulo operator, which can result in zero.

If a new mesocyclone develops, the cycle may start again, producing one or more new tornadoes.

If a purely resistive load is connected to a power supply, current and voltage will change polarity in step, the power factor will be unity ( 1 ), and the electrical energy flows in a single direction across the network in each cycle.

If the amplitude is limited to small swings, the period T of a simple pendulum, the time taken for a complete cycle, is:

If θ is measured in seconds, then the waves e < sup > 2πiθ </ sup > and e < sup >− 2πiθ </ sup > both complete one cycle per second, but they represent different frequencies in the Fourier transform.

If this fragment is part of a larger graph, then any Hamiltonian cycle through the graph must go in or out of the top vertex ( and either one of the lower ones ).

If the same-side forelimb contacts the ground half of the cycle later than the hindlimb, the phase is 50 %.

If the coupling to the electromagnetic field is weak, so that the orbit doesn't decay very much in one cycle, the radiation will be emitted in a pattern which repeats every period, so that the fourier transform will have frequencies which are only multiples of 1 / T.

If the contestant chooses to play, a lighted " spinner " begins moving around the board, while the individual squares on the board cycle through a series of items.

If the animal is allowed to survive after spinning its cocoon and through the pupa phase of its life cycle, it will release proteolytic enzymes to make a hole in the cocoon so that it can emerge as a moth.

If the energy input by the aerodynamic excitation in a cycle is larger than that dissipated by the damping in the system, the amplitude of vibration will increase, resulting in self-exciting oscillation.

If the source is totally inductive ( capacitive ), then a totally capacitive ( inductive ) load, in the absence of resistive losses, would receive 100 % of the energy from the source but send it back after a quarter cycle.

If hand-washing detergent is accidentally used, the foam may be removed by spraying with salt, and the dishwasher should be forced into a drain cycle to remove the detergent and water.

If we consider a pulse waveform with a low value, a high value and a duty cycle D ( see figure 1 ), the average value of the waveform is given by:

If the area was to become habitable and productive all year, the cycle of flood and drought had to be replaced with a reliable supply of water that could be controlled year-round.

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

If the Otto cycle is abandoned, however, and fuel is injected directly into the combustion-chamber during the compression stroke, the petrol engine is liberated from a number of its limitations.

If the observational record is long enough and conditions are stationary ( i. e. there is no significant long-term trend ), a meaningful annual cycle will result that can be used to calculate an anomaly time series.

If this happens, there may be some class conflict in the South, with school boards and school teachers taking the middle-class position.

If that happens, then he will be holding worthless stock at the end of the game.

If the relative priorities of these substituents need to be established, R takes priority over S. When this happens, the descriptor of the stereocenter is a lowercase letter ( r or s ) instead of the uppercase letter normally used.

If this process happens faster than it is naturally quenched by ions recombining, the new ions multiply in successive cycles until the gas breaks down into a plasma and current flows freely in a discharge.

If this happens to all industries however, everyone would be worse off than if they had been subject to the rigours of market competition.

If this happens rapidly before significant decay to the organic tissue, very fine three-dimensional morphological detail can be preserved.

If a statement happens to be true in our world, but is false in some other worlds, then it is a contingent truth.

# If the borrowed word happens to have a suffix that the borrowing language uses as a gender marker, the suffix tends to dictate gender.

If one thinks in this manner, then consider what happens when the story is extended further.

If the manoeuver is timed properly, Mars will be " arriving " under the spacecraft when this happens.

To Axel Oxenstierna, he confessed: " If anything happens to me, my family will merit your pity, the mother lacking in common sense, the daughter a minor-hopeless, if they rule, and dangerous, if others come to rule over them.

If no additional energy is supplied by any other mechanism, the nucleus will not fission, but will merely absorb the neutron, as happens when U-238 absorbs slow and even some fraction of fast neutrons, to become U-239.

The Code of Canon Law 332 § 2 states, " If it happens that the Roman Pontiff resigns his office, it is required for validity that the resignation is made freely and properly manifested but not that it is accepted by anyone.

If this happens, normal drainage of mucus within the sinuses is disrupted, and sinusitis may occur.

If most evolution happens in these rare instances of allopatric speciation then evidence of gradual evolution in the fossil record should be rare.

If this happens, the resulting lever angle created will not be as effective as if aligned with the oarlock or slightly behind it.

If the payout is 4, 000 times the input amount, and it happens every 4, 000 times on average, the return to player is exactly 100 %, but the game would be dull to play.

If this happens in an even dimension, the Majorana spinor representation will sometimes decompose into two Majorana – Weyl spinor representations.

If the demand decreases, then the opposite happens: a shift of the curve to the left.

If the quantity supplied decreases, the opposite happens.

If the third offence happens, 2 points will be given to the player.

If that happens, Franks said, “... the Western world, the free world, loses what it cherishes most, and that is freedom and liberty we ’ ve seen for a couple of hundred years in this grand experiment that we call democracy .” Franks then offered “ in a practical sense ” what he thinks would happen in the aftermath of such an attack.

If emergence happens over disparate size scales, then the reason is usually a causal relation across different scales.

If the convex hull of X is a closed set ( as happens, for instance, if X is a finite set or more generally a compact set ), then it is the intersection of all closed half-spaces containing X.

# Handling: If it is anticipated that overflow may occur and when it happens detected and other processing done.
