AGE-RELATED HEARING IMPAIRMENT (ARHI): A COMMON SENSORY DEFICIT IN THE ELDERLY

2011

This paper aims to give a broad overview of the scientific findings related to Age-related hearing impairment that is a complex disorder, with both environmental as well as genetic factors contributing to the impairment. The involvement of several environmental factors has been partially elucidated. A first step towards the identification of the genetic factors has been made, which will result in the identification of susceptibility genes, and will provide possible targets for the future treatment and/or prevention of ARHI.

TCO/Ag/TCO transparent electrodes for solar cells application

2014

Among transparent electrodes, transparent conductive oxides (TCO)/metal/TCO structures can achieve optical and electrical performances comparable to, or better than, single TCO layers and very thin metallic films. In this work, we report on thin multilayers based on aluminum zinc oxide (AZO), indium tin oxide (ITO) and Ag deposited by RF magnetron sputtering on soda lime glass at room temperature. The TCO/Ag/TCO structures with thicknesses of about 50/10/50 nm were deposited with all combinations of AZO and ITO as top and bottom layers. While the electrical conductivity is dominated by the Ag intralayer irrespective of the TCO nature, the optical transmissions show a dependence on the natur…

Audiologic profile of OSAS and simple snoring patients: the effect of chronic nocturnal intermittent hypoxia on auditory function

2016

The objective of this work was to study the effect of nocturnal intermittent hypoxia on auditory function of simple snoring patients and subjects affected by OSAS; we compared the audiologic profile with the severity of OSAS to detect early signs of cochlear damage. One hundred-sixty patients underwent overnight polysomnography, micro-otoscopy, multi-frequency audiometry, acufenometry, TEOAE recording and d-ROMs test. All subjects were divided in four groups, based on presence/absence of AHI (simple snoring without OSAS, mild OSAS, moderate OSAS, severe OSAS). Sixty (37.5 %) patients were not affected by OSAS, 58 (36.25 %) presented a mild OSAS, 18 (11.25 %) a moderate OSAS and 24 (15 %) a …

Electrosynthesis of Sn-Co nanowires in alumina membranes

2010

A fabrication process of amorphous nanowires of Sn-Co alloys, based on electrodeposition into anodic alumina membranes, is described. It is shown that nanowires of tin-cobalt alloys with different compositions can be produced by varying electrodeposition time and concentration ratio of salts dissolved into the electrolytic bath. Importance of the chelating agent to produce amorphous Sn-Co alloys has also been addressed. Electrodepositions were carried out potentiostatically at -1 V versus Saturated Calomel Electrode and 60 degrees C for times ranging from 10 to 90 minutes; the atomic fraction of Co2+ in the aqueous electrolyte (Co2+/(Co2+ + Sn2+)) was varied from 0.33 to 0.67. Nanowires asp…

STRUCTURATION EXTENSIVE ET TRANSTENSIVE AU DEVONO-DINANTIEN DU BASSIN DE TIM MERSOÏ (BORDURE OCCIDENTALE DE L'AÏR, NORD NIGER).

2007

International audience; L'étude tectono-sédimentaire préliminaire du bassin de Tim Mersoï confirme le contrôle exercé par les accidents majeurs N-S d'In Azaoua-Arlit, N30°E de Madaouéla et N70°E de Tin Adrar sur la géométrie du remplissage sédimentaire. Pour la période dévono-dinantienne, deux phases majeures de structuration ont été mises en évidence : une phase extensive, multi-épisode (du Dévonien au Viséen supérieur) et une phase transtensive débutant au Viséen terminal. Ces deux phases tectoniques majeures sont responsables de l'ouverture polyphasée du bassin. Pendant la phase extensive, la direction d'allongement qui était globalement N90°E au Dévonien, devient successivement N70°E pu…
