“…Limitations, of course, may be imposed by our use of the far-field approximation in the calculation and the fact that we neglected any inhomogeneities in the plasma. The results are also similar to radiation patterns found in ordinary acoustic waves, which are also longitudinal waves [Hueter and Bolt, 1955].…”

“…The comparatively low intensity of cavitation in trifluoroacetic acid is noted experimentally by the small amount of noise produced during ultrasonic disintegration, and the small amount of breakdown of the wool. There is little doubt that the low intensity of cavitation is due to the low surface tension of trifiuoroacetic acid, although its abnormally high vapour pressure may also be a contributing factor (Hueter and Bolt 1955). It is not clear why the amount of disintegration in dimethyl sulphoxide is higher than expected or that of glacial acetic acid is less than expected (Table 5).…”

“…Thus, for a particular intensity of cavitation, the rate of disruption will increase with increased swelling (hence decreased strength) of the fibres. However, the intensity of cavitation varies from one liquid to another and is known to decrease with decrease in the surface tension of the liquid (Noltingk andNeppiras 1950, 1951) and also appears to be a complex function of the vapour pressure and the viscosity of the liquid (Hueter and Bolt 1955). The comparatively low intensity of cavitation in trifluoroacetic acid is noted experimentally by the small amount of noise produced during ultrasonic disintegration, and the small amount of breakdown of the wool.…”

SummaryA study is made of the disruption of wool by ultrasonic disintegration and the separation and identification by microscopy of the major components of the fibre. The ultrasonic disintegration process is investigated empirically in order to establish the conditions under which maximum rates of disruption occur. Of a large number of liquids examined it is found, in confirmation of earlier work, that the rate of disintegration of wool is very slow in water but usually increases in amount as the swelling of the fibre increases. The several exceptions to this rule show that there are other factors of secondary importance in determining the rate of disruption. The amount of disruption is sufficient for preparative purposes and increases in amount in the series dimethyl sulphoxide, formic acid, and dichloroacetic acid.Cortical cells, cuticle, and disrupted cortical cells can be separated on the basis of their different sizes by a combination of screening and sedimentation methods. The histological purity of the fractions is established by light and electron microscopy. It is also shown that the random nature of the ultrasonic disruption process results in the production of components of a continuous range of sizes from cortical cells down to needle· like components of size approaching that of microfibrils.

“…The oscillographic display of reflected echoes from tissue interfaces depends upon the acoustic impedance of the reflecting substance and the angle of incidence of the sound beam (12). Tissue in terfaces with large changes in acoustic impedance may reflect enough of a differential echo to permit these interfaces to be identified.…”
