A review of the techniques using ultrasonic waves for the measurement of stress within materialsdoi:10.1016/0041-624X(70)90764-XUltrasonics
What’s more, with careful control of the ultrasonic transducers, it’s possible to control the rotation of the target — allowing researchers to produce 3D scans of the insects using just one camera. There isn’t a whole lot of technical detail on the device itself, other than the fact ...
This paper presents the results of a series of experiments which were conducted to study the feasibility of using the photoelastic method to observe ultrasonic waves in a large plate on quantitative basis. The frequency used was as high as 0.79 MHz. Due to inherent limitations of the power of...
Continuous monitoring of the central blood pressure waveform from deeply embedded vessels such as the carotid artery and jugular vein has clinical value for the prediction of all-cause cardiovascular mortality. However, existing non-invasive approaches,
Today, ultrasonic(超声的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解,使溶解) in...
The effectiveness of the velocity model improved when Vp was modeled as a function of these investigated parameters collectively rather than in isolation. Thus, an integrated study such as multi-regression analysis would help to present a more realistic picture that affect the relations between ...
There are 2 main types of cataract surgery. The more common type is called phacoemulsification (phaco) or "Ultrasonics." The doctor makes a tiny incision in the eye and breaks up the lens using ultrasonic waves. The lens is removed, and an intraocular lens (IOL) is put in its place. In...
These experiments suggest phenomena of constructive interference after SWT in smaller well plates. Cardiomyocytes and fibroblast inevitable receive SWT during direct epicardial application to the heart. To evaluate whether SWT induces necrosis in other cardiac domestic cells, we subjected cardio myocytes and...
We then employ a high-tech device that looks like a small massage tool. The TED handpiece is moved slowly over the scalp, emitting safe ultrasonic sound waves and air pressure. (This process is known as sonophoresis.) The 20-25-minute process gently enhances the...
During this period, the sloped wetland was irrigated via sprinklers using shallow groundwater from a well located approximately 50 m from the wetland. In April 2017, treated effluent from the wastewater treatment plant was first introduced to the horizontal levee at a total flow of 265 m3 d−...
