If the consonant is voiced, the voicing is the only sound made during occlusion ; if it is voiceless, a stop is completely silent.

If the occlusal surfaces of the teeth or the supporting structures have been altered due to inappropriate dental treatment, periodontal disease, or trauma, the proper occlusion may need to be restored.

If the decrease in blood pressure is systemic ( rather than occlusion of the renal artery ) baroreceptors in the carotid sinus and aortic arch will be stimulated.

If the development of the stenosis or occlusion is gradual blood supply to the tissues and organs slowly diminishes until organ function becomes impaired.

If the patient's occlusion does not permit for a mildly-retentive restoration, or if there is too much decay or a fracture within the tooth structure, a porcelain or composite veneer may not be placed with any adequate guarantee for its durability.

" Late vs Early Clamping of the Umbilical Cord in Full-term Neonates ," JAMA, March 21, 2007 ) If the umbilical cord is not clamped, and it is not during an extended-delayed cord clamping protocol, a physiological postnatal occlusion occurs upon interaction with cold air, when the internal gelatinous substance, called Wharton's jelly, swells around the umbilical artery and veins.

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 a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

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 he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

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

If part of the heart seems to receive an insufficient blood supply, coronary angiography may be used to identify stenosis of the coronary arteries and suitability for angioplasty or bypass surgery.

* If the posterior descending artery ( PDA ) ( a. k. a. posterior interventricular artery ) is supplied by the right coronary artery ( RCA ), then the coronary circulation can be classified as " right-dominant ".

* If the posterior descending artery ( PDA ) is supplied by the circumflex artery ( CX ), a branch of the left artery, then the coronary circulation can be classified as " left-dominant ".

* If the posterior descending artery ( PDA ) is supplied by both the right coronary artery ( RCA ) and the circumflex artery, then the coronary circulation can be classified as " co-dominant ".

If one coronary artery is obstructed by an atheroma, the second artery is still able to supply oxygenated blood to the myocardium.

If acute coronary syndrome (" unstable angina ") is suspected, many people are admitted briefly for observation, sequential ECGs, and determination of cardiac enzymes over time.

If one is to evaluate ischemia ( reductions in coronary blood flow resulting from coronary artery disease ) then individuals must be studied under " stress " conditions and comparisons require " stress-stress " comparisons.

If the heart rate is very fast, and the patient has underlying coronary artery disease ( obstruction of the arteries of the heart by atherosclerosis ), chest pain similar to angina may be experienced ; this pain is band-or pressure-like around the chest and often radiates to the left arm and angle of the left jaw.

If the ECG confirms changes suggestive of myocardial infarction ( ST elevations in specific leads, a new left bundle branch block or a true posterior MI pattern ), thrombolytics may be administered or primary coronary angioplasty may be performed.

If this is positive, coronary angiography is typically performed on an urgent basis, as this is highly predictive of a heart attack in the near-future.

If the clot travels into a coronary artery it can cause a heart attack.

If anticoagulant therapy is contraindicated and / or ineffective, or to prevent new emboli from entering the pulmonary artery and combining with an existing blockage, an IVC filter may be implanted.

If a stethoscope is placed over the brachial artery in the antecubital fossa in a normal person ( without arterial disease ), no sound should be audible.

For the cardinal Etchegaray, former bishop of Marseille, the Virgin de la Garde " does not form only part of the landscape like Chateau d ' If or the Old Port, but it is the living heart of Marseille, its central artery more than the Canebière.

If the usual resting pulse pressure is consistently greater than 100 mmHg, the most likely basis is stiffness of the major arteries, aortic regurgitation ( a leak in the aortic valve ), arteriovenous malformation ( an extra path for blood to travel from a high pressure artery to a low pressure vein without the gradient of a capillary bed ), hyperthyroidism or some combination.

* If the ventilations are successful, assess for the presence of a pulse at the carotid artery.

If atheroma, or clots, are protruding into the lumen, producing narrowing, the narrowing may be seen instead as increased haziness within the X-ray shadow images of the blood / dye column within that portion of the artery ; this is as compared to adjacent, presumed healthier, less stenotic areas.

If the pulmonary arterial pressure is more than 2 / 3 the systemic systolic pressure, there should be a net left-to-right shunt of at least 1. 5: 1 or evidence of reversibility of the shunt when given pulmonary artery vasodilators prior to surgery.

( If eisenmenger's physiology has set in, it must be proven that the right-to-left shunt is reversible with pulmonary artery vasodilators prior to surgery.

If the dorsal scapular artery comes off the transverse cervical artery, the parent transverse cervical artery splits, the dorsal scapular artery passes medially, while the transverse cervical artery passes laterally.
