Effects of ultrasonic irradiation upon Amoeba proteus.
The irradiation of living organisms with ultra sound causes effects in several ways (E l’p in er1) . High intensities damage the cells markedly, causing irreversible cell changes, rupture of cell walls etc. But even low intensities of ultrasound have been shown to affect cell parameters (see review by H ill2) . In this paper we will show some qualitative results of ultrasonic irradiation of Am...
متن کاملEffect of ultrasonic irradiation on the dissociation of antigen-antibody complexes. Application to homogeneous enzyme immunoassay.
The effect of ultrasonic irradiation on the dissociation of antigen-antibody complexes was studied. Among three frequencies tested, 28 kHz ultrasound gave a relatively high percent dissociation with the lowest decrease of immune reactivity. When dissolved antigen-antibody complexes were exposed to the ultrasonic irradiation no dissociation was observed, while antigenantibody complexes were sign...
متن کاملOptimum Application of Ultrasonic Peening
A new advanced system for Ultrasonic Peening (UP) of materials, details and welded elements was developed recently. The UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The beneficial effect is achieved mainly by relieving o...
متن کاملApplication and Research of Ultrasonic Horn in Ultrasonic Ranging System
Aiming at the problem that echo signal is hard to recognize caused by ultrasonic energy’s overquick dispersion and attenuation, a kind of ultrasonic horn is designed. According to the acoustic theory analysis, the ultrasonic horn can increase its radiation energy by improving impedance matching. The ultrasonic horn can make the directivity of sound source sharper and energy more centralized bec...
متن کاملPreparation of Fullerene Function Materials under Ultrasonic Irradiation : Review
Oxygen adducts were among the first reported fullerene derivatives, and they have continued to be the subject of many subsequent investigations by experimental and theoretical researchers. A literature survey is presented summarizing the preparation, purification, characterization, and stabilities of fullerene oxides and ozonides. Published data on the 13C NMR spectra, thermal dissociation reac...
