# If P, then Q.

# If isotherms are concave towards the " north-east " direction ( 45 °), then adiabats are concave towards the " east north-east " ( 31 °).

# If adiabats and isotherms are graphed severally at regular changes of entropy and temperature, respectively ( like altitude on a contour map ), then as the eye moves towards the axes ( towards the south-west ), it sees the density of isotherms stay constant, but it sees the density of adiabats grow.

# If morality is objective and absolute, God must exist.

# If the beat on the new record hits before the beat on the current record then the new record is too fast, reduce the pitch and manually slow the speed of the new record to bring the beats back in sync.

# If the beat on the new record hits after the beat on the current record then the new record is too slow, increase the pitch and manually increase the speed of the new record to bring the beats back in sync.

# If equals are added to equals, then the wholes are equal.

# If equals are subtracted from equals, then the remainders are equal.

# If the remainder from dividing N by 6 is not 2 or 3 then the list is simply all even numbers followed by all odd numbers ≤ N

# If the remainder is 2, swap 1 and 3 in odd list and move 5 to the end ( i. e. 3, 1, 7, 5 )

# If the remainder is 3, move 2 to the end of even list and 1, 3 to the end of odd list ( i. e. 4, 6, 8, 2-5, 7, 9, 1, 3 )

# If the design is symmetrical in an axis parallel to the flag pole, obverse and reverse will be identical despite the mirror-reversal, such as the Indian Flag or Canadian Flag

# If not, the obverse and reverse will present two variants of the same design, one with the hoist on the left ( usually considered the obverse side, see flag illustrations ), the other with the hoist on the right ( usually considered the reverse side of the flag ).

# If two straight lines in a plane are crossed by another straight line ( called the transversal ), and the interior angles between the two lines and the transversal lying on one side of the transversal add up to less than two right angles, then on that side of the transversal, the two lines extended will intersect ( also called the parallel postulate ).

# Associativity: If a * b and b * c are defined, then ( a * b ) * c and a * ( b * c ) are defined and equal.

# Identity: If a * b is defined, then a * b * b < sup >− 1 </ sup >

# If it persists, " gather facts and seek help.

# If the noun is animate, natural gender tends to dictate grammatical gender.

# 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 the borrowed word rhymes with one or more native words, the latter tend to dictate gender.

# If a project's spending becomes too much for a committee to continue funding, it must take the issue to the Project Committee.

# Affordable premium: If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that the insurance will be purchased, even if on offer.

# If the German Armed Forces ( Wehrmacht ) were not in a position to break the danger from the Eastern front, then Nazi Germany would fall to Bolshevism, and all of Europe would fall shortly afterward ;

# Interference by nontuberculous mycobacteria: Exposure to environmental mycobacteria ( especially M. avium, M. marinum and M. intracellulare ) results in a nonspecific immune response against mycobacteria.

# Interference by concurrent parasitic infection: In another hypothesis, simultaneous infection with parasites changes the immune response to BCG, making it less effective.

# Make sure patient is in an actual comatose state and is not mistaken for locked-in state ( patient will either be able to voluntarily move his eyes or blink ) or psychogenic unresponsiveness ( caloric stimulation of the vestibular apparatus will result in slow deviation of eyes towards the stimulation followed by rapid correction to mid-line ; this response can't be voluntarily suppressed: therefore, if the patient doesn't have this response, then psychogenic coma can be ruled out as a differential )

# The cause of suffering is the mind ’ s struggle in response to challenge.

# Regulation of immune system activity and inflammation: chemokine receptors bind ligands that mediate intercellular communication between cells of the immune system ; receptors such as histamine receptors bind inflammatory mediators and engage target cell types in the inflammatory response

# Relay and amplification of the received hormonal signal via a signal transduction process: This then leads to a cellular response.

# The punster: a variable response, sometimes involving a name ( Doctor )

# The host cell, containing a dormant phage genome, experiences DNA damage due to a high stress environment, and starts to undergo the SOS response.

# The P < sub > R </ sub > and P < sub > L </ sub > promoters are no longer repressed and switch on, and the cell returns to the lytic sequence of expression events ( note that cII is not stable in cells undergoing the SOS response ).
