  • list of william shakespeare screen adaptations

    olivier's first performance of shakespeare on screen. it was also the final film of stage actors leon quartermaine and henry ainley and featured an early screen role for ainley's son richard as sylvius, as well as for john laurie, who played orlando's brother oliver.laurie would go on to co-star with olivier in the three shakespearean films that olivier directed.

  • resonator

    the cavity magnetron is a vacuum tube with a filament in the center of an evacuated, lobed, circular cavity resonator. a perpendicular magnetic field is imposed by a permanent magnet. the magnetic field causes the electrons, attracted to the relatively positive outer part of the chamber, to spiral outward in a circular path rather than moving directly to this anode.

  • surface-mount technology

    surface-mount technology smt is a method in which the electrical components are mounted directly onto the surface of a printed circuit board pcb . an electrical components mounted in this manner is referred to as a surface-mount device smd .in industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because smt allows .

  • ground loop electricity

    ground loop currents can be induced by stray ac magnetic fields b, green which are always present around ac electrical wiring. the ground loop constitutes a conductive wire loop which may have a large area of several square meters. by faraday's law of induction, any time-varying magnetic flux passing through the loop induces an electromotive .
