When switching from 700 stadia per degree to 500, he ( or Marinos ) expanded longitude differences between cities accordingly ( a point first realized by P. Gosselin in 1790 ), resulting in serious over-stretching of the Earth's east-west scale in degrees, though not distance.

When manuals were redrafted in the mid-century, in particular after the 1848 Revolution to formulate a national curriculum, care was taken to distance their approach to rhetoric from that of the Church, which was seen as an agent of conservatism and reactionary politics.

When using a pulsed radar, the variation between the phase of successive returns gives the distance the target has moved between pulses, and thus its speed can be calculated.

When the group's ship suffers a warp core breach and is going to explode, he offers to beam them aboard his ship so they can survive, but they refuse and tell him to move off to a safe distance which he does.

When calling long distance, the calling party would give the name and city of the person desired, and the operator would advise the calling party to hang up and wait for the call to be completed.

When a distance in kilometers ( km ) is divided by a time in hours ( h ), the result is in kilometers per hour ( km / h ).

When proper units are used for tangential speed v, rotational speed ω, and radial distance r, the direct proportion of v to both r and ω becomes the exact equation:

When calculated in this way for the case where ∆ r is a distance along the axis joining the centers of m and M, is directed outwards from to the center of m ( where ∆ r is zero ).

When the cities are viewed as points in the plane, many natural distance functions are metrics, and so many natural instances of TSP satisfy this constraint.

When the player stands within a small distance from most surfaces, the detail texture will fade in and make the surface appear much more complex ( high-resolution ) instead of becoming increasingly blurry.

When a unit comes up, the commander specifies an order and if offensive action is being taken, a target, along with details about distance.

When he arrives, he will call " Butterfly " from a distance, but she will not answer, partly for fun and partly not to die from the excitement of the first meeting.

When a beam is measured with a laser beam profiler, the wings of the beam profile influence the D4σ value more than the center of the profile since the wings are weighted by the square of its distance, x < sup > 2 </ sup >, from the center of the beam.

When disruptive change has penetrated to the third level of social order, the process of disruption rapidly reaches a point of no return.

When this water level has been reached, inject steam into the wheel until the temperature reaches that shown in Column B of Table 2.

When gastric hydrochloric acid reaches the nerves in the gastrointestinal mucosa, they signal pain to the central nervous system.

Neurons generate electrical signals that travel along their axon s. When a pulse of electricity reaches a junction called a synapse, it causes a neurotransmitter chemical to be released, which binds to receptors on other cells and thereby alters their electrical activity.

When the child reaches skeletal maturity ( 18 to 25 years of age ), all of the cartilage is replaced by bone, fusing the diaphysis and both epiphyses together ( epiphyseal closure ).

When the total vapor pressure reaches the pressure surrounding the liquid, boiling occurs and liquid turns to gas throughout the bulk of the liquid.

When the process of escape and return reaches an equilibrium, the vapor is said to be " saturated ," and no further change in either vapor pressure and density or liquid temperature will occur.

) When the orthodromic stimulus reaches the muscle fiber, it elicits a strong M-response indicative of muscle contraction.

When the antidromic stimulus reaches the motor neuron cell bodies, a small portion of the motor neurons backfire and orthodromic wave travels back down the nerve towards the muscle.

When a particular substance, whether chemical or biotic — reaches unsafe levels in the bloodstream, the body can effectively dilute — or at least maintain equilibrium of — the offending substances by storing it in new fat tissue.

When a pilot moves the control column ( or sidestick ), a signal is sent to a computer ( analogous to moving a game controller ) the signal is sent through multiple wires ( channels ) to ensure that the signal reaches the computer.

When the actuator reaches the desired position, the two signals ( incoming and outgoing ) cancel each other out and the actuator stops moving ( completing a feedback loop ).

When he finally reaches the cables, Andoh tries to stop him from releasing them.

A Power stroke: When the piston reaches a point just before top dead center, the spark plug ignites the fuel mixture.

When it reaches the towns of Saugatuck and Douglas it stops and enters Lake Michigan.

When this news of his family ’ s execution reaches him, Macduff is stricken with grief and vows revenge.

When the voltage of C1 right-hand plate ( Q2 base voltage ) becomes positive and reaches 0. 6 V, Q2 base-emitter junction begins diverting a part of R2 charging current.

When the water reaches the coastline, the corresponding coastal ponds, both freshwater and brackish, fill to capacity and beyond, spilling over into the sea.

When the timer reaches 0: 00, the blinds go to a higher level.

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 neurotransmitter is released at a synapse, it reaches its highest concentration inside the narrow space of the synaptic cleft, but some of it is certain to diffuse away before being reabsorbed or broken down.

When the game score reaches three points each, the receiver chooses which side of the court ( advantage court or deuce court ) the service is to be delivered on the seventh and game-deciding point.

When the incident angle is increased sufficiently, the transmitted angle ( in air ) reaches 90 degrees.

# When a pair reaches 5 points in the final game, the pairs must switch ends of the table and the team that receives the service must switch receiver.

When the bus reaches its destination, the passengers on the bus — including the narrator — are gradually revealed to be ghosts.
