Nucleus 22-channel cochlear implant: preliminary observations.
A carefully designed study was undertaken in 1982 to evaluate the performance of individuals who received the Nucleus 22-channel cochlear implant. All patients were profound-totally deaf, adults with a postlingual onset of impairment. The preoperative evaluation, prosthesis fitting, training, and postoperative testing were consistent across clinics. Single-subject studies, where each patient ac...
متن کاملLimited Frequency Range Observations of Cosmological Point Sources
This paper discusses observational relations for cosmological point sources in some specific waveband, and their use in the context of the data provided by the galaxy redshift surveys. By starting from the general theory for observations in relativistic cosmology, developed mainly by G. F. R. Ellis, the equations for colour, K-correction and number counts of cosmological point sources are discu...
متن کاملEquivalent Volume Sources for Explosions at Depth: Theory and Observations
For simple theoretical models of an underground explosion, two apparently different relationships between isotropic moment and volume change have been published. We show that there is no inconsistency, because these relationships are based on two different definitions of volume change at the explosion source. We report observations of three 25-ton chemical explosions conducted in 1997 at the fo...
متن کاملeffects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
15 صفحه اولSuperconductivity at 155 K
Transition to a superconducting zero-resistance state at 155 K is observed for the first time in bulk material. A new five-element compound has been synthesized with nominal composition YIBa2Cu3F20y. Fluorine plays a critical role in achieving this eAect. X-ray diffraction and electron microprobe analysis indicate that the samples are multiphasic. Evidence is presented that the samples contain ...
