Measurement of membrane elasticity by micro-pipette aspiration.
The classical micro-pipette aspiration technique, applied for measuring the membrane bending elasticity, is in the present work reviewed and extended to span the range of pipette aspiration pressures going through the flaccid (low pressures) to tense (high pressures) membrane regime. The quality of the conventional methods for analysing data is evaluated using numerically generated data and a n...
متن کاملThe shear modulus of the human vocal fold in a transverse direction.
The aim of this study was to measure the shear modulus of the vocal fold in a human hemilarynx, such that the data can be related to direction of applied stress and anatomical context. Dynamic spring rate data were collected using a modified linear skin rheometer using human hemilarynges, and converted to estimated shear modulus via application of a simple shear model. The measurement probe was...
متن کاملIntra-operative Laryngoscopic Instrument for Characterizing Vocal Fold Viscoelasticity
INTRODUCTION Our society depends on communication, the most natural form of which is speech. Trauma, disease and the normal aging process will cause many to suffer degraded or lost vocal fold function, and it has been observed that this number is growing [1]. The vocal folds are the vibrating structures in the larynx that enable us to generate voice, from speech to opera singing. The vibrating ...
متن کاملPrediction of the deformation modulus of rock masses using Artificial Neural Networks and Regression methods
Static deformation modulus is recognized as one of the most important parameters governing the behavior of rock masses. Predictive models for the mechanical properties of rock masses have been used in rock engineering because direct measurement of the properties is difficult due to time and cost constraints. In this method the deformation modulus is estimated indirectly from classification syst...
متن کاملMeasurement of Young's modulus of vocal folds by indentation.
OBJECTIVES To assess the accuracy of the indentation method for stiffness measurements and to estimate the Young's modulus of the vocal fold using this technique. STUDY DESIGN Basic science.
