Acoustic properties of the dental vs. alveolar contrast in Mapudungun
نویسندگان
چکیده
In this paper we undertake an acoustic analysis of dental and alveolar segments in Mapudungun, an indigenous language of Chile. We calculate locus equations for dental and alveolar segment pairs of different manners. We find that dentals differ from alveolars of the corresponding manner in lowering the onset F2 of following vowels. We validate these results by means of a linear mixed model analysis.

Investigation of acoustic properties of silica coated gold nanoparticle as contrast agent for Ultrasonography
Interoduction: Ultrasound images have often low contrast due to small differences in acoustic impedance between different tissues. Air or gas microbubbles that surrounded by membrane are most of the contrast agents in ultrasound imaging. Problems such as instability in sound pressure and inability in penetrating from the blood vessel into body tissues limited the use of microbubbles into the in...

Augmentation of deficient and atrophic alveolar ridges is an important aspect of dental implant therapy with the goal of providing a functional restoration in harmony with adjacent natural dentition. Bone splitting technique is considered a distinguished augmentation method for treatment of deficient alveolar ridges. According to this procedure, the compromised alveolar ridge is opened from the...

Introduction: Herpes zoster Infection (HZI) is a viral disease with painful skin rashes and blisters in a limited area on one side of the body, often in a strip. Osteonecrosis with spontaneous exfoliation of teeth in association with HZI of the mandibular nerve is a rare phenomenon. In this report, such an unusual complication of HZI is presented. Case Report: The clinical course of a 53-year...

The current paper presents an acoustic study of Lower Sorbian. Four native speakers of Lower Sorbian participated in this study. Center of gravity, standard deviation, skewness, kurtosis and slope measures were taken to measure the fricatives' spectral qualities. Vocalic transitions were also taken to gather finer grained information about the sibilants' articulation. The results indicated ther...
متن کاملThe Evaluation of Yellow vs. Blue Color Contrast Sensitivity pre and Post LASIK
Introduction: contrast sensitivity is one of the most important psychophysical tests that may be used for the evaluation of refractive state of eye and retinal image quality. Yellow vs. blue color contrast sensitivity may be more suitable in this regard. Materials and Methods: thirty myopic eyes were considered in this study. Yellow vs. blue color contrast sensitivity was evaluated under the sa...
