When the airborne divisions were conceived early in World War II, the Army's senior commanders decided that the glider regiments would have only two battalions each.

When by 1944 it became evident that these two-battalion regiments were not suited to combat operations, certain glider regiments were broken up and their battalions attached to others.

When Langley received word from his friend Octave Chanute of the Wright brothers ' success with their 1902 glider, he attempted to meet the Wrights, but they politely evaded his request.

When a ship foundered, local wreckers would scavenge what they could of the ship's cargo before it sank, hiding their pilfered rum behind, and sometimes in, the same large sand dunes where the Wright Brothers would later perform glider tests, before flying their first plane from level ground nearby.

When they do wear out, it is generally due to ink invading the guide plate of the print head, causing grit to adhere to it ; this grit slowly causes the channels in the guide plate to wear from circles into ovals or slots, providing less and less accurate guidance to the printing wires.

When in 1901, the Russian writer Maxim Gorky turned to the imagery of Subantarctic avifauna to describe Russian society's attitudes to the coming revolution, he used a storm-announcing petrel as the lead character of a poem that soon became popular in the revolutionary circles as " the battle anthem of the revolution ".

When the circles are of equal size, the equation is much simpler, but it still can be solved only approximately.

When several oxen were moved at once, the canoeist guided a lead animal with a rope so that the others would follow ; if, however, the lead animal became confused and started swimming in circles, the other animals followed until they tired and eventually drowned.

When two circles don't meet at all in the real plane ( for example because they are concentric ) they meet at these two points on the line at infinity and two other complex points which do not lie at infinity.

In the box T are two wheels ( as in Dr Long's sphere ) and two pinions, whose axes come out at V and U ; either of which may be turned by the small winch W. When the winch is put upon the axis V, and turn backward, the terrestrial globe, with its horizon and celestial meridian, keep at rest ; and the whole sphere of circles turns round from east, by south, to west, carrying the sun Y, and moon Z, round the same way, and causing them to rise above and set below the horizon.

When several rings or circles were combined representing the great circles of the heavens, the instrument became an armillary sphere.

When focused midway between the sagittal and tangential focusing planes, stars are imaged as circles, making the RCT well suited for wide field and photographic observations.

When the circles were abolished in 1932, the provinces including Nan became the top-level subdivision of Siam.

When the Hussite army faced a numerically superior opponent they prepared carts for the battle by forming them into squares or circles.

When moving at subsonic speed, the Stewart Whizzer can create cyclones ( by running in circles ); run up walls and across water.

When Bambi is later shot by a hunter, the Prince shows him how to walk in circles to confuse the man and his dogs until the bleeding stops, then takes him to a safe place to recover.

When, in 1595, Vieta published his response to the problem set by Adriaan van Roomen, he proposed finding the resolution of the old problem of Apollonius, namely to find a circle tangent to three given circles.

When viewed in monochrome other symbols can look similar, such as the circles within circles, sometimes depicted on their own, sparsely or in clustered groups.

When Britain declared war on Nazi Germany on 3 September 1939, debates began in official circles about the possible ways in which the German military might launch an invasion of the British Isles ; in the first week of the conflict numerous diplomatic and intelligence reports seemed to indicate that there was the possibility of an imminent German amphibious assault.

When Andie and Blane try to get together, they encounter resistance from their respective social circles.

When trying to find the radius of a fourth circle tangent to three given kissing circles, the equation is best rewritten as:

When police arrived, an unsteady Furlong, who " smelled of booze ," began to " turn around in circles " when an officer tried to frisk him.

When attacked by a bird, they run in circles, confusing the enemy.

When sufficiently accurate and complete measurements are available, it will be possible to set limits on the thermal and electrical characteristics of the surface and subsurface materials of the moon.

When energy is in a form other than thermal energy, it may be transformed with good or even perfect efficiency, to any other type of energy, including electricity or production of new particles of matter.

When heat is added to a thermal system, the change in entropy is the increase in mass-energy divided by temperature:

When in thermal equilibrium, then, it is seen that the lower energy state is more populated than the higher energy state, and this is the normal state of the system.

When the core temperature reaches about, the thermal energy dissociates the H < sub > 2 </ sub > molecules.

When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy.

When the turbine is used solely for shaft power their thermal efficiency is around the 30 % mark.

When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermal resistance, can be described.

When thermal resistances occur in series, they are additive.

When a material undergoes a phase change from solid to liquid or from liquid to gas the thermal conductivity may change.

# When the drums are heated by hard braking, the diameter of the drum increases slightly due to thermal expansion, this means the brakes shoes have to move farther and the brake pedal has to be depressed further.

When used well and combined with passive solar design, thermal mass can play an important role in major reductions to energy use in active heating and cooling systems.

When temperatures fall at night, the walls re-radiate the thermal energy back into the night sky.

When molecules are in thermal motion, as they are in the gas and liquid phase, the electrostatic force is averaged out to a large extent, because the molecules thermally rotate and thus probe both repulsive and attractive parts of the electrostatic force.

When capsaicin is present, it alters the conformation of the SERCA, and thus reduces the ion movement ; as a result the ATP energy ( which would have been used to pump the ions ) is instead released as thermal energy.

When the sample and reference are heated identically phase changes and other thermal processes cause a difference in temperature between the sample and reference.

When a body is heated at constant temperature by thermal radiation in a microwave field for example, it may expand by an amount described by its latent heat with respect to volume or latent heat of expansion, or increase its pressure by an amount described by its latent heat with respect to pressure.

When conventional brakes are used, 100 % of the kinetic energy lost is converted to thermal energy, and dissipated in the form of heat.

When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, at which point they are in thermal equilibrium.

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 a planet generates a significant amount of heat internally, such as is the case for Jupiter, convection in the atmosphere can transport thermal energy from the higher temperature interior up to the surface.

When the CPU is idle, it will draw far less than the typical thermal power.

When such a processor reaches a temperature level deemed too high for safe operation, the thermal control circuit activates, automatically decreasing the clock and CPU core voltage until the temperature has returned to a safe level.
