The syndrome is associated with intellectual disability, low muscle tone (hypotonia), characteristic facial features, constipation, Hirschsprung disease (an intestinal condition), epilepsy, short stature, small head (microcephalus) as well as malformations of the heart, brain, genitals, urinary tract and eyes.
An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum , from very-low-frequency ( VLF ) radio to ultraviolet ( UV ) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires.
According to Wikipedia, an EMP is : also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse may occur in the form of a radiated electric or magnetic field or conducted electrical current depending on the source, and may be natural or man-made.The term âelectromagnetic pulseâ is commonly abbreviated to the acronym EMP (which is pronounced by saying the letters separately, âE-M-Pâ).In laymanâs terms, it is an intense burst of electromagnetic energy caused by an abrupt and rapid acceleration of charged particles. This is the pulse from a nuclear blast or other EMP weapon. 2  An E2 is a bit slower than an E1. 3  A bolt of lightning has the characteristics of an E2. 4  Because of this, E2 are typically the easiest to protect against. 5  But a nuclear blast or EMP weapon has the characteristics of both an E1 and an E2 pulse.
