If the medication is mixed with formulas containing iron or soya products, larger doses may be required, as these substances may alter the absorption of thyroid hormone from the gut.

If the ground state has a higher population than the excited state ( N < sub > 1 </ sub > > N < sub > 2 </ sub >), the process of absorption dominates and there is a net attenuation of photons.

If we now subject the atoms to light of a frequency, the process of optical absorption will excite the atoms from the ground state to level 3.

If restricted to absorption lines it would look similar to the illustration ( top right ).

If the star temperature has been determined by a majority of absorption lines, unusual absences or strengths of lines for a certain element may indicate an unusual chemical composition of the photosphere.

If the absorption losses can be neglected, ε is a Hermitian matrix.

If the light were totally reflected then the radiation pressure is doubled compared to total absorption, this is because the photons arrive with momentum E / c and depart with momentum-E / c ( the-ve sign indicates traveling in the opposite direction ), so the change of momentum is 2E / c.

If negative, fluid will tend to enter the capillary ( absorption ).

If absorption of light varies with the angle relative to the optical axis in a crystal then pleochroism results.

If this bandwidth is comparable to the width of the absorption features, then the measured extinction coefficient will be altered.

If cells of different path lengths are available, testing if this relationship holds true is one way to judge if absorption flattening is occurring.

If the highest percentage of absorption of a drug takes place in the stomach, a coating that dissolves quickly and easily in acid will be selected.

If the rate of absorption is best in the large intestine or colon, then a coating that is acid resistant and dissolves slowly would be used to ensure it reached that point before dispersing.

If all terms are specified for a material, at long wavelengths far from the absorption peaks the value of n tends to

If the absorption and emission are repeated many times, the mean velocity, and therefore the kinetic energy of the atom will be reduced.

If we say a little more about what happens to caloric during this absorption phenomenon, we can explain the radiation of heat, the state changes of matter under various temperatures, and deduce nearly all of the gas laws.

" If the matter can be forced out of thermal equilibrium to a sufficient degree, so that the upper state has a higher population than the lower state ( population inversion ), then more stimulated emission than absorption occurs, leading to coherent growth ( amplification or gain ) of the electromagnetic wave at the transition frequency.

If a document is made of a variety of materials, which have different absorption properties, expansion will occur at a non-uniform rate, which could lead to deformations.

If negative, fluid will tend to enter the capillary ( absorption ).

If friction, absorption, electrical resistance or a similar energy conversion takes place that releases heat, the impact of that heat on thermodynamic potentials must be considered, and it is this impact that decreases the available energy.

If a drug is present in the digestive tract ’ s absorption zone for less time its blood concentration will decrease.

If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood reducing the volume of the alveoli, resulting in a form of alveolar collapse known as absorption atelectasis.

If absorption is a physical process not accompanied by any other physical or chemical process, it usually follows the Nernst partition law:

Complementary to R is the transmission coefficient or transmittance, T. If absorption and scattering are neglected, then the value T is always 1 – R.

If, conversely, tin is used to coat steel, when a breach of the coating occurs it actually accelerates oxidation of the iron.

If a cerebral AVM is detected before a stroke occurs, usually the arteries feeding blood into the nidus can be closed off to avert the danger.

If suppuration occurs, it may need needle aspiration.

If this occurs, the referee separates the opponents and orders them to continue boxing.

If an injury occurs, one caver stays with the injured person while the other two go out for help, providing assistance to each other on their way out.

If this occurs, the oil will burn and has to be replaced.

If no bulk flow occurs in an element of length dx, the rates of diffusion of two gases A and B must be equal and opposite, that is.

If we choose the shape of the control volume such that all flow in or out occurs perpendicular to its surface, then the flow of matter into the system performs work as if it were a piston of fluid pushing mass into the system, and the system performs work on the flow of matter out as if it were driving a piston of fluid.

If deactivation occurs during the first reading, the reader does not need to undergo deactivation in the second reading.

If a seizure lasts longer than 5 minutes, or if more than one seizure occurs without regaining consciousness emergency medical services should be contacted.

* If a leap occurs, it must be small and immediately countered by stepwise motion in the opposite direction.

If a mutation occurs within a gene, the new allele may affect the trait that the gene controls, altering the phenotype of the organism.

If the guessing player suggests a letter which occurs in the word, the other player writes it in all its correct positions.

If the value being sought occurs k times in the list, and all orderings of the list are equally likely, the expected number of comparisons is

If bad weather occurs during flowering, the Merlot vine is prone to develop coulure.

If unsuccessful, nothing interesting occurs.

If surviving Linear B clay tablets can be trusted, the name po-se-da-wo-ne (" Poseidon ") occurs with greater frequency than does di-u-ja (" Zeus ").

If there is still a tie for first place, a jump-off occurs to break the tie.

If this occurs, then the vice president will assume the presidential powers and duties as acting president ; however, the president can declare that no such inability exists and resume the discharge of the presidential powers and duties.

If the former occurs, then any subsequent measurement performed by Bob, in the same basis, will always return 1.

If the latter occurs, ( Alice measures 1 ) then Bob's measurement will return 0 with certainty.

If an interrupt occurs that makes a high priority task ready during the insertion of a low priority task, that high priority task can be inserted and run immediately before the low priority task is inserted.

If the full moon occurs on a Sunday, Easter is the following Sunday.

If the full moon occurs on a Sunday, Easter is the following Sunday.

If one throws a die once, it is difficult to predict the outcome, but if we repeat this experiment many times, we will see that the number of times each result occurs divided by the number of throws will eventually stabilize towards a specific value.
