| ultrasonic waves | The periodic configuration of energy produced by sound having a frequency greater than 30,000 Hz. (05 Mar 2000) |

| vegetative propagation | Propagation without pollination by way of separating vegetative parts (i.e., branches, stolons, buds) from the mother plant and planting them so they take root and grow. (09 Oct 1997) |
| propagation | 1. The act of propagating; continuance or multiplication of the kind by generation or successive production; as, the propagation of animals or plants. "There is not in nature any spontaneous generation, but all come by propagation." (Ray) 2. The spreading abroad, or extension, of anything; diffusion; dissemination; as, the propagation of sound; the propagation of the gospel. Origin: L. Propagatio: cf. F. Propagation. Source: Websters Dictionary (01 Mar 1998) |
| ultrasonic | Relating to energy waves similar to those of sound but of higher frequencies (above 30,000 Hz). Origin: ultra-+ L. Sonus, sound (05 Mar 2000) |
| ultrasonic cardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves. (12 Dec 1998) |
| ultrasonic cephalometry | Measurement of the foetal head by ultrasound. (05 Mar 2000) |
| ultrasonic egg recovery | Obtaining an egg for in vitro fertilization by means of an ultrasonically guided needle aspiration of ovarian follicles; may be performed transvesically or via the cul-de-sac. (05 Mar 2000) |
| ultrasonic lithotresis | The demolition of calculi by high frequency sound waves. (05 Mar 2000) |
| ultrasonic microscope | <instrument> A microscope that has lenses designed to use acoustic energy so that the ultrasonic wavelengths may be utilised; by means of transducers, the information is translated to a form that may be visualised or recorded. (05 Mar 2000) |
| ultrasonic nebuliser | A humidifier using high-frequency electricity to power a transducer that vibrates 1,350,000 times per second and changes water up into particles 0.5 to 3 um in size in its nebulizing chamber; used in inhalation therapy. (05 Mar 2000) |
| ultrasonic rays | See: ultrasonic. (05 Mar 2000) |
| ultrasonic scaler | An ultrasonic instrument that uses high frequency vibration to remove adherent deposits from the teeth. (05 Mar 2000) |
| ultrasonic therapy | The use of focused, high-frequency sound waves to produce local hyperthermia in certain diseased or injured parts of the body or to destroy the diseased tissue. (12 Dec 1998) |
| Alfven waves | <physics, radiobiology> Transverse electromagnetic waves that are propagated along lines of magnetic force in a plasma. The waves have frequency significantly less than the ion cyclotron frequency, and are characterised by the fact that the field lines oscillate (wiggle) with the plasma. The propagation velocity depends on the particle density and the strength of the magnetic field. [Relatively] Low frequency ion oscillation in the presence of an equilibrium magnetic field. Also called the transverse hydromagnetic wave along B_0. The torsional Alfven wave in cylindrical geometry was first measured in liquid mercury by B. Lehnert. Alfven waves were first generated and detected in plasma by Allen, Baker, Pyle, and Wilcox in Berkeley and by Jephcott in England in 1959. (13 Nov 1997) |
| radio waves | That portion of the electromagnetic spectrum beyond the microwaves, with wavelengths as high as 30 km. They are used in communications, including television. Short wave or hf (high frequency), uhf (ultrahigh frequency) and vhf (very high frequency) waves are used in citisen's band communication. (12 Dec 1998) |
