Sound Propagation in Lipid Membranes

Low-Frequency Sound Propagation in Lipid Membranes

In the recent years, we have shown that cylindrical biological membranes such as nerve axons under physiological conditions are able to support stable electromechanical pulses called solitons. These pulses sharemany similarities with the nervous impulse, for example, thepropagationvelocityaswell as themeasured reversibleheatproductionandchanges in thickness and length that cannot be explained w...

DYNAMICAL SIMULATION OF UNDERWATER SOUND PROPAGATION IN THE HORMOZ STRAIT

Providing an illustration of sound propagation in the Hormoz Strait ,this paper is about acoustic wave propagation in shallow water for a harmonic point source with low frequency, less than 1000 and solution of a homogenous Helmholtz equation using parabolic equation. C++ programming is used to solve Helmholtz equation [9] and MATLAB software is used to illustrate figures and animate them [6], ...

Sound propagation in colloidal systems

We study the propagation of sound in complex colloidal systems. By combining Biillouin scattering with ultrasonic techniques, we measure the dispersion in the acoustic propagation over three decades in frequency. Acoustic propagation is sensitive to the bulk compressibility of the medium, and probes new structural and dynamic properties of the colloidal system. We study two colloidal systems. T...
