the asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. the rigid disk is assumed to be in frictionless contact with the elastic half-space. by virtue of appropriate green's functions, the mixed boundary value problem is written as a dual integral equation. employing further mathematica...

Purpose Whiplash injury can cause internal derangement of the temporomandibular joint (TMJ) and lead to temporomandibular disorders (TMDs). Our aim was to evaluate whether the initial clinical findings in TMD patients with whiplash injury are correlated with their magnetic resonance imaging (MRI) characteristics. Materials and methods This case-control study involved 219 patients (135 women, ...

AIMS The aim of this work was to evaluate the agreement between temporomandibular joint click sound and MR diagnoses of different disk positions. METHODS One hundred ninety-four (N=194) patients seeking treatment for temporomandibular disorders at the TMD Clinic, Department of Maxillofacial Surgery, University of Padova, Italy, underwent a bilateral magnetic resonance of the temporomandibular...

A prominent feature of striated muscle is the regular lateral alignment of adjacent sarcomeres. An important intermyofibrillar linking protein is the intermediate filament protein desmin, and based on biochemical and structural studies in primary cultures of myocytes it has been proposed that desmin interacts with the sarcomeric protein nebulin. Here we tested whether nebulin is part of a novel...

Objectives: To evaluate the diagnostic accuracy of 3-D computed axiography to detect anterior disk displacements (ADD) of the temporomandibular joint (TMJ). Methods: 564 joints with no disk displacement (NDD), 114 joints with reducible displaced disk (RDD) and 36 joints with permanently displaced disk (PDD) confirmed on magnetic resonance imaging (MRI) were examined by 3-D computerized axiograp...

disk plows are one of the most important tillage tools. two way (reversible) disk plows can perform continues plowing. so they can save time and costs and hence improve overall efficiency. in this study, a “two-way” disk plow was designed based on a λ-formed straight-line, four-bar linkage (daniel mechanism). this design contains disk and rear wheel reversing mechanism, stabilization mechanism ...

Two simultaneous holograms and several directions of observation are utilized to determine the components of displacement and strain in the disk. A reference strip is introduced to relate the fringe orders in the two holograms. A very good agreement is obtained between the holographic results and the elasticity theory solution. The obtained displacement field is estimated to be accurate to 8 x ...

The aim of this study was to determine the correlation between the static and dynamic occlusal factors in patients with anterior disk displacement (DD) and to compare it with occlusion in asymptomatic individuals. The study included a group of 40 patients with DD (median age 35.5) and a control group of 25 students of dental medicine (median age 23.4). In all subjects, the position, i.e. DD was...
