True Strain Characterization for Tmj Disc Tensile Testing
INTRODUCTION The temporomandibular joint (TMJ) is a bilateral synovial joint that is formed by the condyle of the mandible and the glenoid fossa of the temporal bone. In between these two bones is a fibrocartilagenous structure called the TMJ disc. Deterioration or displacement of the TMJ disc can lead to temporomandibular joint disorders (TMDs), which can cause symptoms such as pain, discomfor...
متن کاملLaser Speckle Strain Measurements in Soft Tissue
The importance of understanding the mechanical behavior of tissues is starting to be recognized in medical diagnostics. It is becoming clear that pathological tissues behave mechanically differently than do healthy tissues. However, traditional optical evaluation methods, particularly speckle-based methods, have not proven to be effective in assessing the mechanics of biological soft tissues. T...

Background Autistic Spectrum Disorder (ASD) is a neurodevelopmental disorder. There is a large quantity of evidence which point towards a positive correlation between Autism and Mitochondrial disorders (MD). In addition to that, several published reports, indicate that people with neurological disorders exhibit pathological signs of mitochondrial disorders and vice versa. Screening for underly...
متن کاملMultiscale Computer Simulation of Tensile and Compressive Strain in Polymer- Coated Silica Aerogels
While the low thermal conductivities of silica aerogels have made them of interest to the aerospace community as lightweight thermal insulation, the application of conformal polymer coatings to these gels increases their strength significantly, making them potentially useful as structural materials as well. In this work we perform multiscale computer simulations to investigate the tensile and c...
