Flash causes

Eventually the He burning converts the core to carbon. Core thermonuclear shutdown occurs but fusion continues in the shell around the core, producing He followed by periods of helium flashes, causing wild variations in the luminosity. The Sun will then develop a super wind by convection that will blow off the overshell of the star, leaving a hot core behind. The expelled material forms a shell... 

The arc may appear narrow and filamentary when a xenon flash tube is operated below its maximum input power per flash because not all of the gas is ionized. The position of the arc tends to shift from flash to flash, causing erratic light output. It is generally not advisable to operate a flash tube very far below its maximum input. 

ARC - A flash, caused by an electric current ionizing a gas or vapor. 

Field changes Discrete temporal jumps in the electric field of thunderstorms coincident with lightning strokes or flashes, caused by the neutralization of charges due to lightning currents. 

Dimensional tolerance on hubs and shafts when used as moulding inserts is critical. This is firstly to provide accurate centre location - this obviously will affect the accuracy of the finished gear as a whole - and secondly to avoid flash caused by molten polymer passing between the hub and its location in the tool, where it projects from the gear face. Tolerances of 0.013 - 0.025 mm are generally required. 

The two-phase level in the RPV shows a temporary increase after about 20 seconds due to the flashing caused by the depressurization in the vessel, as illustrated in Fig. IX-6. After the pressures are equalized at around 130 seconds, the two-phase level transient starts gradually decreasing due to the steam collapse with the sub-cooled condensate flow drained from the IC. However, it is kept at the elevation of the broken line since the steam generated in the reactor vessel and the containment now becomes identical. The two-phase level in the RPV is, therefore, kept well above the elevation of the top of active fuel and there is no heat-up in the reactor core. 

Cqiper is the heavy metal most commonly encountered in qrplications of aluminum. A common example is rain runoff from copper roof flashing, causing corrosion of alutninum gutters. A cqrper-ion concen-...
