13. Photosynthetic Responses of Leaves to Water Stress, Expressed by Photoacoustics and Related Methods 1: I. Probing the Photoacoustic Method as an Indicator for Water Stress in Vivo
The effect of leaf desiccation on the photosynthetic activities in vivo was probed by the photoacoustic method. The aim of this research was: (a) To study the photoacoustic signal per se in varied conditions in order to develop this tool as a probe for stress conditions in vivo. (b) To obtain results pertaining to electron transport activities in vivo, and c

14. Material properties from acoustic radiation force step response
An ultrasonic technique for estimating viscoelastic properties of hydrogels, including engineered biological tissues, is being developed. An acoustic radiation force is applied to deform the gel locally while Doppler pulses track the induced movement. The system efficiently couples radiation force to the medium through an embedded scattering sphere. A single
