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.
Specifically, ambulatory electrocardiographic monitoring can detect abnormal electrical activity in the heart which may occur randomly or only under certain circumstances; such as, during sleep or periods of physical activity or stress, which may or may not be picked up by standard, short-term electrocardiography performed in a doctor's office.
The main complaint that people have with ambulatory electrocardiographic monitoring is that the monitor may be cumbersome and interfere with certain activities; especially, sleeping; however, bathing and showering are not allowed during the monitoring period.
The signals of the ambulatory electrocardiographic monitoring are recorded on a cassette tape that runs slowly for a 24 hour recording, then the tape is quickly analyzed by a machine which stops when it detects any abnormalities in the recording.
A typical datum is about 100 and the field is directed vertically in such a way as to drive positive charges downward.2. A quantitative term indicating the electric field strength of the atmosphere at any specified point in space and time.
3. A measure, in volts per meter, of the electrical energy in a given portion of the earth's atmosphere at a given time.
2. The study of electrical processes occurring within the atmosphere.
3. Electrical phenomena, regarded collectively, that occur in the earth's atmosphere.
These phenomena include not only such striking manifestations as lightning and St. Elmo's fire, but also less noticeable but more ubiquitous effects; such as, atmospheric ionization, the air–earth currents, and other quiescent electrical processes.
The existence of separated electric charges in the atmosphere is a consequence of many minor processes; such as, spray electrification, dust electrification, etc. and a few major processes including, cosmic-ray ionization, radioactive-particle ionization, and thunderstorm electrification.
The maintenance of the prevailing atmospheric electric field is now widely believed to be due to thunderstorm effects.
2. A substance that, in solution, conducts an electric current and is decomposed by its passage.
Acids, bases, and salts are common electrolytes.
The fish that utilize such bioelectrogenetic aspects often also possess electroreceptive abilities (which are more widespread) as part of an integrated electric system.
The bioelectrogenetic skills may be utilized for self-defense, electrocommunication, and with the stunning of prey.
2. Relating to the study of electron transfer reactions as they occur in biological, or living systems.
2. The science of electronic effects and controls of living organisms.
