چکیده
Influence of the cheeks expansion during bilabial plosive production This experimental study highlights the influence of expansion of the cheeks during the production of bilabial plosives. The closure of the lips, before the plosive, causes an increase in intra-oral pressure. The assumption suggested in this paper is that the increase of oral cavity volume, as a result of the intra-oral pressure, has a non-negligible impact on the pressure inside the oral cavity. Fisrtly, this phenomenon is shown by in-vivo measurements for an /apa/ utterance, then reproduced in laboratory on a replica of human vocal apparatus. The upper part of vocal tract is represented by a flexible tube, whose volume increases under the effect of the pressure. MOTS-CLÉS : Production de la parole, plosives bilabiales, aérodynamique, mesures in-vivo/invitro, pression intra-orale.

Physical modeling of vowel-bilabial plosive sound production
Downstream of the vocal folds, it is often assumed that all the kinetic energy of the glottal jet is dissipated by turbulence. Although this assumption is reasonable for normal voicing, there are many configurations for which a constriction or even an occlusion of the vocal tract occurs and leads to a significant pressure recovery. Such a phenomenon occurs during the production of vowel-bilabia...

This study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (Camelus dromedarius). Milk samples representing the wet and dry seasons were analyzed for total solids (TS), fat (F), solids-non-fat (SNF), ash, crude protein (CP), nitrogen soluble at pH 4.6 (SN), mineral content (MC) and casein fraction (CnF). Camel milk had higher (P
