The error incurred in the representation of contact pressure at edges incomplete contacts by first order asymptotes is treated, and maximum value relative found for a range geometries, both symmetric non-symmetric. For power-law geometry, we identify when first-order asymptote achieves fidelity. Shear tractions are excited application shear force bulk tension one body. An asymptotic traction di...

BACKGROUND The causative role of diffuse macular edema in various etiologies is often undetermined. OBJECTIVES To describe an association between extrafoveal vitreous traction and non-diabetic diffuse macular edema secondary to various ocular entities. METHODS In a retrospective study of eyes with non-diabetic diffuse macular edema, charts and optical coherence tomography scans demonstratin...

INTRODUCTION Vitreomacular traction syndrome has recently been recognized as a distinct clinical condition. It may lead to many complications, such as cystoid macular edema, macular pucker formation, tractional macular detachment, and full-thickness macular hole formation. CASE PRESENTATION We report a case of vitreomacular traction syndrome with eccentric traction at the macula and a partial...

background: traction has been suggested to be an effective treatment for symptoms of neck disorder in patients with no contraindications. however, according to previous researches, the effectiveness of traction is controversial, particularly compared to other conservative treatments. this trial was conducted to evaluate the effect of sustained traction, using an over-the-door home cervical trac...

A numerical boundary integral method, relating slip and traction on a plane in an elastic medium by convolution with a discretized Green function, can be linked to a slip-dependent friction law on the fault plane. Such a method is developed here in two-dimensional plane-strain geometry. The method is more efficient for a planar source than a finite difference method, and it does not suffer from...

We simulate the response of dense granular material to shear. Our simulations use a micromechanical model which includes realistic material models for each deformable grain, and a Coulomb friction model for interactions between grains. We measure the probability density function (PDF) governing the volume distribution of stress for monodisperse and polydisperse samples, circular and polygonal g...
