effect- The local electrical change triggers a wave of excitation that travels rapidly along the cell and initiates processes leading to contraction. c. Contractility-Muscle cells are unique in their ability to shorten substantially when stimulated.-This enable them to pull on bones and other organs to create movement. d. Extensibility- In order to contract‚ a muscle cell must alson be extensible able to stretch again between contractions.- Most cells rupture if they are stretched even a

Vahala California Institute of Technology‚ Mail Stop 128-95‚ Pasadena‚ California 91125‚ USA (e-mail: vahala@caltech.edu) Optical microcavities confine light to small volumes by resonant recirculation. Devices based on optical microcavities are already indispensable for a wide range of applications and studies. For example‚ microcavities made of active III–V semiconductor materials control laser emission spectra to enable long-distance

Permanent-magnet brushless dc and ac machines and drives are compared in terms of their constant torque and constant power capabilities‚ and various PM machine topologies and their performance are reviewed. Finally‚ methods for enhancing the PM excitation torque and reluctance torque components and‚ thereby‚ improving the torque and power capability‚ are described.

In contrast to chemical synapses‚ the postsynaptic potential in electrical synapses is not caused by the opening of ion channels by chemical transmitters‚ but by direct electrical coupling of the neurons. Electrical synapses are therefore faster and more reliable than chemical

even in the most rudimentary acts‚ reflexes‚ considered before as a mechanical response to excitation‚ are discovered by physiologists‚ an intrinsic purpose sufficient to indicate that in them the mental character begins with their specific character. The defensive positions‚ implicit in the reflexes that reveal an inner impulse. They are also discovered in other irreflexive and involuntary acts (contraction of physiognomy‚ blushing‚ etcetera)‚ and acquire undeniable subsistence in the volunteers

ABSTRACT: Transmission or distribution of 5o Hz or 60 Hz electrical energy from the generating point to the consumers’ end without any physical wire has yet to as a familiar and viable technology. This paper focuses on the past and future possible advancements in WPT and explaining why it has still not come into practical utility. Wireless energy transfer has been around for about a century‚ but as of yet has only found usage in things like electric toothbrush rechargers and specialty applications
