ultrasonic - Learn about ultrasound a noninvasive technique heatiness that uses sound waves to image and treat tissues in the body Find out how ultrasound works what it is used for and what are the risks and benefits The effect which is known as piezoelectric was generally discovered by Jacques and Pierre Curie in 1880 which was useful in transducers to generate and detect ultrasonic waves in air and water Ultrasonic Frequency The term that is sounds with a frequency of 20 kHz and higher are said to be referred to as ultrasound or we can say ultrasonic Ultrasound National Institute of Biomedical Imaging and Nov 1 2019 The ultrasonic method was used to quantify the C physicallyprotected in macro and microaggregates Macroaggregates accumulated higher amounts of C C Ma than microaggregates C Mi The amount of C Ma stock in all landuse systems ranged from 33 to 8 Mg ha 1 and the C Mi ranged from 11 to 7 Mg ha 1 This represents around 22 to 4 and How does ultrasound work Uses of ultrasound Ultrasonics is a nondestructive testing technique that uses highfrequency sound waves to detect and size defects in welded structures It also has applications in sonochemistry
