By autumn 1917, however, these attempts at peaceful resolution had failed, and the power vacuum began to be filled by the paramilitary troops of the right and left.

In military dictatorships, or governments which have arisen from coups d ' état, the position of commander-in-chief is obvious, as all authority in such a government derives from the application of military force ; occasionally a power vacuum created by war is filled by a head of state stepping beyond his or her normal constitutional role, as King Albert I of Belgium did during World War I.

Behind the scenes, however, Menzies ' retirement had created a power vacuum in the party, and internal divisions soon emerged.

A partial vacuum, or rough vacuum, can be created using a positive displacement pump that transports a gas load from an inlet port to an outlet ( exhaust ) port.

In petrol engines, instead, vacuum is obtained as a side-effect of the operation of the engine and the flow restriction created by the throttle plate.

A torricellian vacuum is created by filling with mercury a tall glass container closed at one end and then inverting the container into a bowl to contain the mercury.

In December 1918, Mitteleuropa was obsolete as the Germans withdrew from the Ober-Ost territory, and for the next few years in the newly created political vacuum the territories of Belarus would witness the struggle of various national and foreign factions.

The sound source was a series of vacuum tubes which created 10 preset electronic drum sounds.

Nevertheless, as a result a power vacuum was created in Central Europe-especially after Poděbrady himself died later that same year.

Hoyle proposed that hydrogen is continuously created in the universe from vacuum and energy, without need for universal beginning.

As the throttle is opened up slightly from the fully closed position, the throttle plate uncovers additional fuel delivery holes behind the throttle plate where there is a low pressure area created by the throttle plate blocking air flow ; these allow more fuel to flow as well as compensating for the reduced vacuum that occurs when the throttle is opened, thus smoothing the transition to metering fuel flow through the regular open throttle circuit.

The vacuum is created and maintained by a series of pumps.

However, this improved relationship came at a cost, as the death of Shinzon may have created a power vacuum.

However, metal electrode surfaces can cause a region of the vacuum to become conductive by injecting free electrons or ions through either field electron emission or thermionic emission.

These regions may be initiated by field electron emission, but are then sustained by localized thermionic emission once a vacuum arc forms.

Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube.

In the early cold cathode vacuum tubes, called Crookes tubes, this was done by using a high electrical potential between the anode and the cathode to ionize the residual gas in the tube ; the ions were accelerated by the electric field and released electrons when they collided with the cathode.

Modern vacuum tubes use thermionic emission, in which the cathode is made of a thin wire filament which is heated by a separate electric current passing through it.

After the 1690 invention of the vacuum pump by Otto von Guericke, physicists began to experiment with passing high voltage electricity through rarefied air.
