HYPOTHESIS The aim of this study was to investigate the impact of cochlear implant electrode insertion on middle-ear low frequency function in humans. BACKGROUND Preservation of residual low frequency hearing with addition of electrical speech processing can improve the speech perception abilities and hearing in noise of cochlear implant users. Preservation of low frequency hearing requires a...

Neuroevolutionary models are used to predict magnetic hysteresis for barium hexaferrites (to hexaferrites). Magnetic a specific set of samples hexaferrite doped with titanium were measured experimentally at room temperature and reported before. Neural networks trained using these experimental data in order generate magnetization various concentrations titanum. We present the prediction methods ...

rehabilitation of facial defects is a complex task, requiring an individualized design of the technique for each patient. the disfigurement associated with the loss of an eye may result in significant physical and emotional problems. various treatment modalities are available, one of which is the use of implants. although implant-supported orbital prosthesis has a superior outcome, it may not b...

Giovanni Filippo Ingrassia revisited and redefined some of Galeno's reports, and was recognized as one of the leading Italian Physicians of the 16th century. Ingrassia principally studied the skull, and gave very important contributions to otorhinolaryngology, including the discovery of the stapes. He also isolated the inferior nasal concha from the maxillary bone, described the frontal sinus, ...
