It is known that the scattering of ultrasound by cavitation bubbles reduces the efficiency of treatment by high-intensity focused ultrasound. In the authors' experiments striving to reduce grating lobe levels of annular arrays they observed less microbubble formation at the focus of the transducer when pseudorandom phase-modulated CW signals were used(More)
Within the hyper-arid to semiarid areas of Israel three experimental drainage basins varying in area, climate, monitoring duration and type have been being research-monitored. Lessons derived from a large number of published and ongoing research projects on these experimental basins focus on runoff and sediment in drylands. The effect of the spatial(More)
