electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
2. The process of recording and analyzing the electric action potentials that result from uterine muscular contractions.
2. Electrophoresis in which an antigen migrates from a well through agar gel containing antiserum, forming cone-shaped (rocket) precipiting bands.
The area under the cone is used to calculate the amount of antigen.
2. Immunodiffusion in which the antigens are separated according to their migration in an electric field.
Immunodiffusiion is the technique for analyzing antigen (a protein molecule that often protrudes from the surface of a cell which can induce an immune response) and antibody mixtures by watching them as they diffuse toward each other within a support medium (usually a gel).
2. A narrow belt of intense electric current flowing through the lower ionosphere in the equatorial and polar regions which creates auroras.
3. A stream of electricity moving in the upper atmosphere around the equator and also in polar regions, where it produces auroras.
2. A reference to one of the four types of electrokinetic effects:
- streaming potential
- sedimentation potential
The surface is ordinarily either a solid particle suspended in the solution or the medium through which the solution flows.
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.
2. An instrument used to measure ocean current velocities based on their electrical effects in the magnetic field of the earth.
3. A device for determining the motion of ocean water by measuring its electric potentials as it moves through the earth's magnetic field.
2. A device that provides a continuous recording of the movements of an internal body organ; such as, the heart, generally by recording the movements or the changes in density of the shadow of the organ as presented on a fluoroscope.
3. An appliance which combines a photoelectric recording system with a fluoroscope in order to make it possible for the continuous recording of the movements of a shadow within the fluoroscopic field or of changes in density in that shadow.
It is used especially with electrocardiography to study heart motions.2. The photography on x-ray film of the motions of the heart or of other moving structures which can be visualized radiographically.
3. The technique of recording the motions of a bodily organ with an electrokymograph.
2. An instrument for recording the activity of the vocal cords during respiration and phonation or the rapid, periodic opening and closing of the glottis through separation and apposition of the vocal cords that, accompanied by breath under lung pressure, constitutes a source of vocal sounds.
The electrolaryngograph consists of a pair of electrodes, one for application to either side of the neck adjacent to the larynx, a generator, an amplifier, and an oscilloscope.
