An Overview of the Predictive Maintenance Applications of Airborne Ultrasound Testing
نویسنده
چکیده
Detection of Low Frequency (around 40kHz) Ultrasound is a powerful method for maintenance inspection of plant and machinery. Many failure conditions give early indication by the production of ultrasound. These include pressure leaks, electrical discharge and deterioration of bearings and other machinery. Leakage of compressed air has become a particular issue recently with the promotion of energy / CO2 emission reduction initiatives – most estimates suggest that in excess of 5% of industrial energy use represents wasted compressed air. This talk will briefly discuss the operating principles and typical equipment, and give detailed examples of industrial, transport, military and aerospace applications.

An overview of therapeutic applications of ultrasound based on synergetic effects with gold nanoparticles and laser excitation
Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells. The existence of dissolved gases and also the presence of nanoparticles (NPs) in a liquid, irradiated by ultrasound, decrease the acoustic cavitation onset threshold and the resulting bubbles collapse. On the other hand, due to unique capabilities and optical properties of gold nanoparticles (...
متن کاملUltrasound Condition Monitoring
Instruments based on airborne/structure borne ultrasound technology offer many opportunities for reducing energy waste and improving asset availability in plants. They expand the concept of ”Condition Monitoring” to include much more than basic mechanical fault inspections. Since these instruments detect friction, ionization and turbulence, their inspection capabilities range from trending bear...

Background: Hepatocellular carcinoma (HCC) is common all over the world as well as Iran. The incidence of HCC is higher in hepatitis B carriers and it is highly recommended to periodically screen these patients by serum alpha-fetoprotein (AFP) and liver ultrasound (US) every 6 months. We explore the diagnostic accuracy and the performance of (AFP) in cases of hepatitis B carriers as a scree...
