When scratched with a sharp implement, an exothermic reaction occurs and white fumes are given off as metallic antimony is formed ; when rubbed with a pestle in a mortar, a strong detonation occurs.

When the moisture content evaporates during detonation, cooling occurs, which reduces the temperature of reaction.

When detonation occurred the Tu-95V fell one kilometer from its previous altitude due to the shock wave of the bomb.

* When a shockwave is created by high explosives such as TNT ( which has a detonation velocity of 6, 900 m / s ), it will always travel at high, supersonic velocity from its point of origin.

When the cell current changed a certain amount in a certain time interval, the detonation was triggered.

When unburned fuel / air mixture beyond the boundary of the flame front is subjected to a combination of heat and pressure for a certain duration ( beyond the delay period of the fuel used ), detonation may occur.

When a nuclear detonation occurs in air near sea level, much of the released energy interacts with the atmosphere and creates a shockwave which expands spherically from the hypocenter.

When Archer orders the initiation of the detonation sequence, however, Shran obliges and releases it.

When thrown against a hard surface, the impact is sufficient to detonate the tiny quantity of explosive, creating a small report from the supersonic detonation.

When they impact they result in what can only be described as a huge nuclear detonation capable of tremendous damage ; next to Zeorymer's final attack it is one of the most powerful seen in the series.

When used in a turbine engine, the effects are similar, except that preventing detonation is not the primary goal.

When the system runs out of fluid the derichment valve shuts and cuts off the water injection system, while enriching the fuel mixture to provide a cooling quench to prevent sudden detonation.

When surface to air missiles became capable of hitting high flying aircraft bombers, bombers used flight at low altitude to evade radar detection.

When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle.

When a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is called a pressure altimeter or barometric altimeter.

When an object's altitude is 0 °, it is on the horizon.

When considering the power gain for a particular direction given by an elevation ( or " altitude ") and azimuth, then:

When the astrolabe is held vertically, the alidade can be rotated and the sun or a star sighted along its length, so that its altitude in degrees can be read (" taken ") from the graduated edge of the astrolabe ; hence the word's Greek roots: " astron " ( ἄστρον )

When an aircraft is flying at an altitude that is approximately at or below the same distance as the aircraft's wingspan or helicopter's rotor diameter, there is, depending on airfoil and aircraft design, an often noticeable ground effect.

When he is ordered to fly one mission at low altitude to increase accuracy, Davenport rushes to headquarters and confronts his friend, Brigadier General Frank Savage ( Gregory Peck ), the A-3 ( Assistant Chief of Staff for Operations ) of VIII Bomber Command.

When Earhart was at cruising altitude and midway between Lae and Howland ( over from each ) neither station heard her scheduled transmission at 0815 GCT.

When used this way, a navigator will from time to time measure the sun's altitude with a sextant, then compare that with a precalculated altitude based on the exact time and estimated position of the observation.

When seen from high altitude s, the gradient in the sky's color varies from pale to dark at Horizontal coordinate system | elevations approaching the zenith

When the pilot chooses to pull up to enter a thermal or to dive to exit a sink area, an uncompensated variometer will include the change in altitude due to the change in velocity in its read-out, thus marring the airmass ' climb or sink rate.

When used to describe how high something like an airplane or mountain peak is from sea level, height is more often called altitude.

When Japanese planes attacked, Chennault's doctrine called for pilots to take on enemy aircraft in teams from an altitude advantage, since their aircraft were not as maneuverable or as numerous as the Japanese fighters they would encounter.

When used to transport skiers, funitels are a fast way to get to a higher altitude.

When operating at or below the TA, aircraft altimeters are usually set to show the altitude above sea level.

When 1013 hPa ( hectopascal or millibar ) is set on an altimeter subscale the aircraft's vertical position ( in feet, divided by one hundred ) is referred to as a Flight level instead of an altitude.

When he reached a point at which the sun was at a pre-calculated altitude above the horizon, the pilot then made a 90 degree turn to the left ( or right as pre-calculated ) and then flew along this line until the destination was reached.

When they reached an altitude of 4700 m the sun had risen and the snow cover partly melted, which made further expedition impossible.

When operating in an environment with lower air pressure like high altitude or airplane cabins.

When the bomb was delivered by low-level toss bombing, the aircraft was almost always at a lower altitude than the burst height ; so in effect, the bomb was not really " dropped ", but was released and " flew " upwards in a ballistic trajectory, to detonate when it reached the required altitude.

When Heidegger and Sartre speak of a contrast between being and existence, they may be right, I don't know, but their language is too philosophical for me.

When they express themselves it is incandescent hatred that shines forth, the rage of repudiation, the ecstasy of negation.

When I try to work out my reasons for feeling that this passage is of critical significance, I come up with the following ideas, which I shall express very briefly here and revert to in a later essay.

When the proprietor dies, the establishment should become a corporation until it is either acquired by another proprietor or the government decides to drop it.

When the reactionary response is thus bolstered by an intellectual defense, the characteristics of that defense are explicable only in terms of the basic attitudes of unanalyzed reaction.

When I take over Taliesin, the first thing I'll do is fire you ''.

When someone in the audience rose and asked how does it feel to be a celebrity, Carl said, `` A celebrity is a fellow who eats celery with celerity ''.

When decision makers act within this frame they determine whether a claim put forward in the name of religion is to be accepted by the larger community as appropriate to religion.

When we consider the disorganized state of the world community, and the legacy of predispositions adversely directed against all who are identified as Jews, it is obvious that the struggle for the minds and muscles of men needs to be prosecuted with increasing vigor and skill.

When we turn to Aristotle's ideas on the moral measure of literature, it is at once apparent that he is at times equally concerned about the influence of the art.

When their faith in civil liberties is tested against strong pressures of social expediency in specific issues, e.g., suppression of `` dangerous ideas '', many waver and give in.

There is, of course, nothing new about dystopias, for they belong to a literary tradition which, including also the closely related satiric utopias, stretches from at least as far back as the eighteenth century and Swift's Gulliver's Travels to the twentieth century and Zamiatin's We, Capek's War With The Newts, Huxley's Brave New World, E. M. Forster's `` The Machine Stops '', C. S. Lewis's That Hideous Strength, and Orwell's Nineteen Eighty-Four, and which in science fiction is represented before the present deluge as early as Wells's trilogy, The Time Machine, `` A Story Of The Days To Come '', and When The Sleeper Wakes, and as recently as Jack Williamson's `` With Folded Hands '' ( 1947 ), the classic story of men replaced by their own robots.

When I first came across Samuel Johnson's pronouncement, `` the remedy for the ills of life is palliative rather than radical '', it seemed to me to sum up the profoundest of political and social truths.
