Optical Nanotransmission Lines: Synthesis of Planar Left
... Similar formulas may be derived for more complex shapes for the nano-particles. In particular, a DPS nano-particle corresponds to a nano-capacitor, since its permittivity is positive, whereas a plasmonic nano-particle acts as a nano-inductor as observed from outside, due to its negative permittivity ...

Direct-acting valves open or close orifices by direct action of the core; pilot-operated valves for larger lines or higher pressures supplement this direct action by utilizing line pressure to open larger orifices while keeping solenoid size small. Normally ...

... Have a second participant come to the front and empty the contents of Bag B onto the table. Ask them to predict, based on the findings of the previous test, which objects will be attracted to the magnet. Upon actual testing, they will discover that only some of the metals in Bag B are attracted. 3. ...
