Purpose: Divergence insufficiency is characterized by esotropia at far distance with symptomatic diplopia, minimal or no deviation near distance, and full ocular duction version. We analyzed the results of bilateral lateral rectus (BLR) tucking in patients divergence insufficiency.Methods: Surgery was performed on persistent diplopia for least 6 months after onset. The surgical were evaluated B...

Abstract This paper aims to interpret the coupling modal properties of cyclic blades under impact–friction interactions and their evolution mechanism versus operating points. Therefore, a analytical model is developed based on Lagrange method assumed mode (AMM), after considering centrifugal stiffening, spin softening, stagger angle, twist angle. Then mixed analysis (MMAM) for this extended by ...

It is well known that general relativity an effective theory of gravity at low energy scale, and actually quantum effects cannot be ignored in the strong-field regime. As a strong gravitational object, black hole plays key role testing In this paper, we focus on loop investigate what influences are weak bending angles light rays. We find could Schwarzschild hole, regular one-way traversable wor...

the alluvial fan of shahdaad in derakhtangaan river is one of the biggest alluvial fans in a dry area in northeastern kerman. this alluvial fan has been formed due to different material erosions in the drainage basin of derakhtangaan river and lying of these materials in the extreme part of this basin called dasht-e-lut (the plain of lut). the region which has been studied in this research is o...

PURPOSE The objective of this study was to determine whether biomechanical and neuromuscular risk factors related to abnormal movement patterns increased in females, but not males, during the adolescent growth spurt. METHODS A total of 315 subjects participated in two testing sessions approximately 1 yr apart. Male and female subjects were classified on the basis of their maturation status as...

The stability of the photon beam position on synchrotron beamlines is critical for most if not all synchrotron radiation experiments. The position of the beam at the experiment or optical element location is set by the position and angle of the electron beam source as it traverses the magnetic field of the bend-magnet or insertion device. Thus an ideal photon beam monitor would be able to simul...

A tunnel junction cascaded semiconductor laser with thin waveguide and narrowed spacing between adjacent emitters is designed in this work. It can be concluded theoretically that the spatial size of spots arrangement fast axis has a greater impact on vertical beam parameter product (BPP) multi-emitter than divergence angle. The measured BPP narrow emitter (NES) been reduced 42.5%, which implies...

purpose: to evaluate visual outcomes and intraocular pressure (iop) after single-site phacotrabeculectomy with mitomycin c in patients with senile cataract and primary open angle glaucoma (poag), pseudoexfoliative glaucoma (pxg), or chronic angle closure glaucoma (cacg). methods: in this retrospective study, patients older than 50 years who had significant cataracts (bcva £ 20/60) and uncontrol...
