When an HTML page is rendered in a browser, the browser downloads the HTML into local memory and parses it, using the DOM to construct the internal data structures employed to display the page in the browser window.

When a system, for example, n moles of a gas of volume V at pressure p and temperature T, is created or brought to its present state from absolute zero, energy must be supplied equal to its internal energy U plus pV, where pV is the work done in pushing against the ambient ( atmospheric ) pressure.

When internal combustion engines appeared, they had neither the strength nor the ruggedness compared to the big steam tractors.

When an object is not perfectly solid, internal vortices will tend to damp torque-free precession, and the rotation axis will align itself with one of the inertia axes of the body.

When the Taiping Rebellion broke out in 1850s, the Qing court found out belatedly that the Banner and Green Standards troops could neither put down internal rebellions nor keep foreign invaders at bay.

When the material is cooled below the critical temperature, we would observe the abrupt expulsion of the internal magnetic field, which we would not expect based on Lenz's law.

When faced with internal dissent within his own party his main opponent Idrissa Seck was arrested, accused of treason.

When large tidal flows enter the Strait and the high tide relaxes, internal waves are generated at the Camarinal Sill and proceed eastwards.

When it first launched the internal conflict in Peru in 1980, its stated goal was to replace what it saw as bourgeois democracy with " New Democracy ".

When creating this chapel the monks of Peterborough had thought of how they had acquired it and built into the chapel a narrow tower-just big enough for a monk to climb to the top by an internal stair and stand guard over Oswald's Arm 24 hours a day, every day of the year.

When the Treaty of Versailles confirmed the Japanese claim to Shandong and Beijing's sellout became public, internal reaction was shattering.

When a body rotates while subject to tidal forces, internal friction results in the gradual dissipation of its rotational kinetic energy as heat.

When the opposition controls the National Assembly ( and thus government funding and most legislation ), the President is in effect forced to choose a Prime Minister from the opposition ; in such cases, known as cohabitation, the government controls internal state policy, with the President restricted largely to foreign affairs.

When the cohesive forces between like molecules are greater than the adhesive forces, the dissimilarities of polarity or internal pressure will lead both components to escape solution more easily.

When Plissken reluctantly agrees to attempt the rescue, Hauk has him injected with microscopic explosives that will rupture his carotid arteries in 24 hours.

When blood pressure rises, the carotid and aortic sinuses are distended, resulting in stretch and, therefore, activation of the baroreceptors.

When there is a decrease in the blood's pH, a decrease in oxygen ( pO < sub > 2 </ sub >), or an increase in carbon dioxide ( pCO < sub > 2 </ sub >), the carotid bodies and the aortic bodies signal the medulla oblongata ( specifically the dorsal inspiratory center in the medulla oblongata ) to increase the volume and rate of breathing.

When the internal carotid artery becomes completely blocked, the fine collateral circulation that it supplies is obliterated.

When the sternocleidomastoid muscle is drawn backward, the artery is seen to be contained in a triangular space known as the carotid triangle.

When the ventricle starts contracting, deoxygenated blood is pumped through the pulmonary artery to the lungs.

When a thrombus occupies more than 75 % of cross-sectional area of the lumen of an artery, blood flow to the tissue supplied is reduced enough to cause symptoms because of decreased oxygen ( hypoxia ) and accumulation of metabolic products like lactic acid.

When she was three, it was discovered she had a hole in her heart and a blocked pulmonary artery.

When he saw it for himself in 1851, he pronounced himself " somewhat disappointed in it " but still left a vivid description of its interior, which was more like an underground marketplace than a transport artery:

When Harold was a teen, he punctured an artery on a broken bottle.

When the stent / balloon device is positioned within the stenosis, the balloon is inflated which, in turn, expands the stent and the artery.

When they are used to compress an artery to forestall bleeding they are called hemostats.

When the anterior cerebral artery constricts, reining in the response to this increased blood volume, the pain disappears.

When a balloon catheter is used to compress plaque within a clogged coronary artery it is referred to as a plain old balloon angioplasty or POBA.

When the cardiologist subsequently deflates the balloon the stent stays behind in the artery and the balloon catheter can be removed.

When these cells clump together, they form a clot, sometimes large enough to block the artery.

When damaged or obstructed, it can result in anterior spinal artery syndrome, with loss of urinary and fecal continence and impaired motor function of the legs ; sensory function is often preserved to a degree.

When performed over the fifth intercostal space, it allows optimal access to the pulmonary hilum ( pulmonary artery and pulmonary vein ) and therefore is considered the approach of choice for pulmonary resection ( pneumonectomy and lobectomy ).

When high-grade renal artery stenosis is documented and blood pressure cannot be controlled with medication, or if renal function deteriorates, invasive procedure may be resorted to.

When dissected, the dissection usually includes the region from the bifurcation of the aorta to the superior mesenteric artery or the renal veins.

When the artery's pulse is re-detected through the Doppler probe the pressure in the cuff at that moment indicates the systolic pressure of that artery.
