Ultrasonic

2015
The use of ultrasonic (US) force field to aid both air- and liquid-based separation processes has gained an increasing recognition in recent years. The advantages expected from using US for separation processes include higher liquid removal rate, higher dry matter content in product, lower processing temperature, maintenance of product integrity, more ...

Ultrasonics in dentistry [PDF]

open access: possibleThe Journal of Prosthetic Dentistry, 1956
PPROXIMATELY ONE HUNDRED YEARS ago, it was learned that certain crystal A elements contracted in a magnetic field. Shortly thereafter a similar property was discovered in certain metals which, if rod-shaped, contracted in the direction of their long axes.

ULTRASONIC PELVIMETRY

Obstetrical & Gynecological Survey, 1972
In recent years a high accuracy in measuring the biparietal diameter by ultrasonography has been achieved. As this is only one parameter in forecasting cephalo‐pelvic disproportion a study was made to determine whether the true conjugate can be measured by utrasound with approximately the same reliability as the biparietal diameter.

Ultrasonic Tomography by Means of an Ultrasonic Fiberendoscope

Endoscopy, 1980
The diagnositc value of ultrasonic tomography of the upper abdominal organs is sometimes limited by bones and gas. Endoscopic ultrasonography (EUST) combines the advantages of the direct visualization of the upper GI tube and the ultrasonic imaging of adjacent organs.

Ultrasonic Liposculpturing

Aesthetic Plastic Surgery, 1992
The author describes a revolutionary body contouring technique based on the surgical use of ultrasonic energy. It allows the selective destruction of only excess adipose tissue. The technique is based on three fundamental steps: (1) preparation of the areas to be treated with a large infiltration of a special solution, (2) treatment of the areas with ...
