Several authors have recently demonstrated the intimate relationship between nonlinear dynamics and observations in vocal fold vibration (Herzel, 1993; Mende, Herzel, & Wermke, 1990; Titze, Baken, & Herzel, 1993). The aim of this paper is to analyze vocal disorders from a nonlinear dynamics point of view. Basic concepts and analysis techniques from(More)
Earlier investigation did not show any clear distinctive pathological features that differentiate vocal polyps from vocal nodules. The light microscopic distinctive features between the two lesions point in the direction of a more pronounced epithelial reaction and a more fibrous stromal change in vocal nodules. In the present study, 19 vocal polyps and 11(More)
OBJECTIVE This study aimed to evaluate stress patterns generated within implant-supported mandibular overdentures retained by two different attachment types: ball and socket and locator attachments. MATERIALS AND METHODS Commercial CAD/CAM and finite element analysis software packages were utilized to construct two 3D finite element models for the two(More)
Functional dysphonia is a term applied to voice disorders for which there is an absence of apparent structural change in the larynx. The aim of this work was to investigate how functional dysphonia may differ acoustically from other types of dysphonia. Fundamental frequency profiles for steady vowels were generated using a software program called GLIMPES(More)
UNLABELLED Most scholars, old and modern, agree that the vowel system of the Arabic language is composed of 3 vowels only, namely /i/, /ε/ and /u/. The spoken Cairo dialect suggests that there are 6 identifiable vowels, with a short and long variant for each. OBJECTIVE The aim of this study is to test the validity of the notion that there are 6 × 2(More)
The aim of this work was to study the function of the left and right cerebral hemispheres concerning linguistic, musical and cognitive abilities, through the evaluation of the deterioration of these domains following lesions of either hemisphere. The study was carried out on 80 subjects (60 males, 20 females) with a mean age of 48 years. Subjects were(More)
