Electric Impedance of Piezoelectric Ceramics under Acoustic Loads

Autor: Francisco J. Arnold, Marcos S. Gonçalves, Leonardo L. Bravo Roger, Sérgio S. Mühlen

Publikováno v: ECTI Transactions on Electrical Engineering, Electronics, and Communications. 12:48-54

The electric impedance of piezoelectric ceramics is influenced by variations in the acoustic load. This situation is very common for ultrasonic applications in medicine where the irradiated media can present different interfaces and impedances to the

Phacoemulsification in hard cataracts: the 'chop, trip and free' technique Facoemulsificação em cataratas duras: 'Faco rasteira'

Autor: José Marcos S. Gonçalves

Publikováno v: Arquivos Brasileiros de Oftalmologia, Vol 67, Iss 4, Pp 603-605 (2004)

Very hard cataracts continue to be a challenge to phacoemulsification due to the difficulty in breaking the nucleus and also in separating the broken nucleus from the adjacent epinucleus. The present technique is the presentation of a surgical maneuv
