Uusing functional genomics to study the effect of toxic substances on living organisms.

The science which deals with sound and its relationship to electricity: Loudspeakers and microphones are examples of the applications of electroacoustics.

Electroacoustics is also used in sound broadcasting, sound recording and reproduction as well as ultrasonic flaw detection and technology.

1. The measurement of the speed of military projectiles with electronic equipment.
2. The art or science of measuring the force or velocity of projectiles by using electricity.

Glazing with optical properties that can be varied continuously from clear to dark with a low-voltage signal.

Ions are reversibly injected or removed from an electrochromic material, causing the optical density to change.

The use of electrical and electronic devices administered for diagnostic purposes.

This technique is helpful in almost all branches of medicine, but particularly when investigating the functions of the heart, nerves, and muscles.

1. The study of the relationships between electromagnetic and mechanical phenomena.
2. A branch of physics that studies how electric currents interact with magnetic and mechanical force including the the mutual influence of electric currents, the interaction of currents and magnets, and the influence of an electric current on itself.
3. The study of electrostatic charges in motion; such as, the flow of electrons in an electric current.
4. The science of energy transformations as related to electric currents and their magnetic fields.

1. Use of the flow of high-pressure combustion gas to generate electricity; especially, in high-voltage electric-power generation, air-pollution control, and paint spraying. 2. The conversion of heat energy into electricity by sweeping charged particles through an electric field in a stream of gas.

Electrogasdynamics is a procedure for generating electricity. Small particles of dust, smoke, fog, etc are charged in a low-voltage region and then transported by a gas stream to a high-voltage region, where the charges are removed.

Work is done on the particles in moving them against the electric field and electricity is generated.

A reference to the measurement which tests the degree of the sense of taste by applying a direct electrical current to various parts of the tongue.

A technique for noninvasively measuring the mechanical properties and hemodynamic characteristics of the vascular system, including arterial blood pressure, electric impedance, blood flow, and resistance to blood flow.

The conversion of electrical energy into mechanical or chemical energy by the controlled discharge of high-voltage electric arcs submerged in water or another fluid.

1. The study of the motion of electric charges.
2. The branch of physics that deals with electric currents or electricity in motion.
3. A branch of physics dealing with the steady motion of charges and the behavior of charged particles in electric and magnetic fields.

In physics, the branch concerned with the relationships between electric currents and their associated magnetic fields.

1. The science and technology of electromechanical devices, systems, or processes.
2. The technology of mechanical devices, systems, or processes which are electrostatically or electromagnetically actuated or controlled.
3. The branch of electrical engineering concerned with machines producing or operated by electric currents.

1. The area of science devoted to the directing and guiding of electron beams using electric fields in the same manner as lenses are used on light beams.
2. The study of the motion of free electrons under the influence of electric and magnetic fields; as in laser technology, light amplificaion, and photoelectricity.
3. The science that deals with the direction, deflection, or focusing of beams of electrons by electric and magnetic fields; such as, in electron lenses.
4. The science of the control of electron motion by electron lenses in systems or under conditions analogous to those involving or affecting visible light.
5. A branch of electronics concerned with the behavior of the electron beam under the influence of electrostatic and electromagnetic forces.
6. The science of the emission and propagation of electrons and of the factors controlling and modifying their flow; especially, when applied to electron microscopy.
7. The science and technology concerned with the use of applied electrical fields to generate and to control optical radiation.

The term electron-optics is often used erroneously as a synonym for optoelectronic.

1. The study and application of the conduction of electric charges in various media, including vacuums, gaseous media, and semiconductors.
2. The science of all systems involving the use of electrical instruments used for communication information processing, and control.
3. That field of science and engineering which deals with electron systems, circuits, and devices that control the flow of electrons.
4.The name given to that branch of electrical engineering that deals with tools the operations of which depend on the movement of electrons in space as opposed to the movement of electrons in liquids or solid conductors; for example, radio tubes, photoelectric cells, etc.
