CASCADE FAILURE [3 records]

Record 1 2019-02-18

English

Subject field(s)
  • Electronic Defects and Failures
  • Testing and Debugging
  • Engineering Tests and Reliability
CONT

Two or more failures may occur sequentially starting from a cause. This sequential or consecutive propagation is called a cascade or sequential failure. An accident scenario consists of a mixture of parallel and cascade failures.

Record 2 2009-10-15

English

Subject field(s)
  • Atomic Physics
CONT

When an ionizing particle enters the device, it collides with gas atoms and strikes electrons from their orbit around the nucleus of the gas atoms. In addition, an ionizing particle striking the outside of the tube can also knock electrons off the metal casing. In either case, these free electrons then are attracted to the positively charged central wire, gaining energy by the attraction. As they approach the wire they knock electrons off other atoms, creating an avalanche or cascade effect which results in a pulse of current large enough to be detected. A "quenching gas" is usually added to the filler gas so that these avalanches will dissipate over time and not continue indefinitely, which would cause inaccuracy or electronic failure.

Record 3 1999-10-05

English

Subject field(s)
  • Genetics
CONT

A Novel Mutation in the Sex Determining Region on Y(SRY) Gene as an Etiology of Familial Swyer Syndrome. Swyer Syndrome(SWY) is a failure of testicular differentiation that results in 46, XY sex reversed females. Unlike sporadic SWY, familial cases of SWY appear to be transmitted through 46, XX carrier females and maybe due to X-linked or autosomal genes downstream from SRY in the sexual differentiation cascade. Carriers of a mutation in SRY would be expected to be affected with SWY and be sterile. This report describes two siblings with SWY who have been previously found to have a normal SRY gene with polymerase chain reaction(PCR)
