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.
Electrical submersible pumps. The electrical submersible pump, typically called an ESP, is an efficient and reliable artificial-lift method for lifting moderate to high volumes of fluids from wellbores. These volumes range from a low of 150 B/D to as much as 150,000 B/D (24 to 24,600 m3/d). Variable-speed controllers can extend this range significantly, both on the high and low side. The components are normally tubing hung from the wellhead with the pump on top and the motor attached below.
