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.
EMF is a file extension for Enhanced MetaFile, a spool file format used in printing by the Windows operating system. When a print job is sent to the printer, if it is already printing another file, the computer reads the new file and stores it, usually on the hard disk or in memory, for printing at a later time. EMF files may be created and reside in memory or disk space when windows cache s them while waiting on another printing job.
