In contrast to direct current (which was difficult to transmit more than ten miles), polyphase AC systems proved capable of transmitting power hundreds of miles.
The Arunta Inlier is an extensive east-west-trending, polyphase , high-grade, predominantly Palaeoproterozoic metamorphic complex.
New palaeomagnetic data from Lower Carboniferous granitoids of the orogenic root of the eastern Variscan belt show a polyphase palaeomagnetic record.
The polyphase tectonic and sedimentological development of East African continental rift basins is well-illustrated in the Kilombero Rift Valley in Tanzania.
The reduction in the die area dedicated to capacitance opens up the possibility of building more complex RF circuits, such as image-reject mixers and polyphase IF filters.
The Energy Policy Act of 1992 required minimum efficiency standards for general purpose, polyphase induction motors.
The Moine rocks widely record polyphase deformation and metamorphism up to amphibolite facies.
Precambrian metamorphism and migmatization and the wide spectrum of mainly Alpine mica ages provide clear evidence for such a polyphase geological history.
Isolates underwent polyphasic analyses employing phenotypic (selective media and biochemical testing) and genotypic (polymerase chain reaction) assays to determine species identification.
Electromyography may show short-duration, small-amplitude, polyphasic motor units with an increased terminal innervation ratio (number of fibers innervated by a single anterior horn cell).
