Retroplacement and torsional manipulation of the globe during forced duction testing provide an exaggerated traction test of the oblique muscles, allowing graded evaluation of superior oblique and inferior oblique tightness. On a scale from 0 to 4 +, normal superior oblique tightness averages 1.5+, and normal inferior oblique tightness averages about 1+. The degree of superior oblique or inferi...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...

BACKGROUND Congenital superior oblique palsy is usually associated with a structural abnormality of the superior oblique tendon. There have been many reports of familial congenital superior oblique palsy. However, there has been no MRI documentation of familial superior oblique hypoplasia. METHODS Ophthalmological examination and orbital MRI were performed in three patients in a pedigree with...

conclusions the study findings indicate that short-term exercises had no significant effect on the ratio of vmo to vl muscle fiber angles in patients with pfps. results there were no significant differences in the muscle strength and fiber angle of the vmo, vl oblique and longus muscles after training between the control and experimental groups (p > 0.05). patients and methods thirty-five subje...

Inter particular contacts between particles are of great interest, as the intensity and quantity impact behavior a wide variety industrial processes. The coefficient restitution is commonly used to describe collision particle either with other or walls components plant equipment. considers amount energy that dissipated in event. Usually examined by use high speed cameras image velocimetry. In t...

The Milky Way has a giant stellar structure in the solar neighborhood, which has a size of ∼ 1 kpc, a mass of ∼ 106M⊙, and a ring-like distribution of young stars. Fundamental physical properties of this local enigmatic structure, known as the Gould belt (GB), have not been reproduced by previously proposed models. We first show that the local enigmatic structure can be formed about 30 Myr ago ...
