With a cochlear implant, deaf people are able to understand speech under good listening conditions . Problems occur in adverse conditions, e .g . in reverberant and/or noisy environments . Experiments were carried out to improve the intelligibility of noisy speech using two different single-channel noise suppression techniques . This was realized by preprocessing, i .e . by applying the resynth...

The present paper concerns fundamental aspect of Sign Language, from historical elements at international and national levels to taxonomical for a better understanding pragmatic language. taxonomy Language is difficult task since the analysis isolates processes which, in fact, may intervene create sign. In application part we will focus on proposal Romanian final there are examples context five...

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

the ion-pair association constant values, related to the reaction +  were determined by means of the nmr spectroscopy. the values of the thermodynamic functions of the ion pairing process were calculated on the basis of the nmr results. in addition, the association entropy was found to be dependent on the temperature. comparing the experimental data and the fuoss theory it is found that  ion-pa...

in this paper, the photochemical degradation of azure-b by cu2+/s2o82− process has beenpresented. cu2+ as photocatalyst and s2o82− ion as photooxidant used in this process. atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.the influence of various parameters on the performance of the treatment process has beenconsidered, such as ph, concentration o...

a new, simple, rapid, and cheap method for determination of trace amounts of nitrite ion is reported.determination is based on reduction of bromate ion by nitrite ion, in the presence of murexide inacidic media. during reaction of bromate ion with nitrite ion, the reaction mixture is decolorized.the absorbance changes is then monitored spectrophotometricaly at 520 nm, at 25 °c. dynamicrange of ...

The aims were to determine the benefit of bilateral cochlear implantation in a 20 years old patient implanted in Croatia on hearing and speech development. The male patient, after 10 years of deafness, got cochlear implants Med-EL Combi 40+ on both sides in one-stage surgery. The etiology of his deafness was posttraumatic meningitis. Auditory capacity and speech recognition tests were performed...
