1581. Abstract
... Tumor Growth Inhibition by Local Activation of Cellular Sensitivity to Drugs by Focused Acoustic Shock Waves . ... Development of methods for efficient delivery of drugs to the cells of certain tissues or organs is given high priority in up-to-date medicine and biology. ... It is shown experimentally that the use of ASW increases considerably the in vivo and in vitro cell membrane permeability and can be used to promote targeted delivery of drugs, including fragments of nucleic acids, to cells. ...

1582. Abstract
... Tuning-Fork Investigation of Shear Stresses Nonlinearity in Thixotropic Media . ... A mechanical resonator (tuning fork) oscillates near the resonance frequency f0 in the medium under investigation. The amplitude of its oscillations depends on a shear modulus of the medium. ... As a result the amplitude of resonance oscillations of a tuning fork changes, and also oscillations with combination frequencies of f0 and 2f appear. ...

... Ultrasonic Characterization of the Nonlinear Elastic Properties of Materials . ... Even though many of the characteristics of elastic wave propagation in materials have been known for years, others have still not been determined. ... The characteristics of low-amplitude linear elastic waves are understood much better than those associated with nonlinear elastic waves. ... This paper will summarize the nonlinear effects associated with elastic wave propagation in these more realistic materials. ...

... Ultrasonic Stimulation of Extraction Processes . ... These goals could be achieved using ultrasonically-assisted extraction due to considerable increase in the rates of mass transfer under ultrasonic action. ... Preliminary data show that the application of ultrasound can considerably increase the rates of diffusion and mass transfer and thus decrease the extraction time, temperature, increase the yield of products and improve their quality. ... Water and water-alcohol extraction was investigated. ...

... Ultrasonic Technology of Immunomagnetic Microspheres Fabrication . ... A concave piezoceramic transducer, radius of curvature 50 mm, diameter 40 mm was used to generate ultrasound field at 880 kHz. The piezoceramic transducer with a wave-guide, 15 mm diameter of the radiating surface, was used to generate ultrasound at 21.7 kHz. ... Maximal effect have been achieved by using combined field generated by simultaneously operated high frequency (880 kHz) and low frequency (21.7 kHz) transducers. ...

... Ultrasound in Interface Tension Measurement . ... A lot of different techniques of the surface and interfacial tension measurement are used in the basic researches and for solving a number of practical problems. Almost every method is based on the interaction of the liquid surface (or liquid-liquid interface) with a foreign solid body surface. ... The method is based on the well-known effect of button appearance in the surface of liquid (or liquid-liquid interface) caused by radiation pressure. ...
