“Pattern of ocular morbidities among pilgrims attending religious mega festive event-'Kumbh Mela 2019' at Prayagraj, India”

Journal of Family Medicine and Primary Care, 2020
Background: Globally, ocular morbidities are one of the most underdiagnosed, underreported, and undertreated public health concern. Among estimated 39 billion blind in world, India shares major proportions, with majority of them living in rural ...

Independent and reciprocal accommodation in anisometropic amblyopia [PDF]

, 2010
Accommodation is considered to be a symmetrical response and to be driven by the least ametropic and nonamblyopic eye in anisometropia. We report the case of a 4-year-old child with anisometropic amblyopia who accommodates asymmetrically, reliably ...

Motor nucleus activity fails to predict extraocular muscle forces in ocular convergence

Journal of Neurophysiology, 2011
For a given eye position, firing rates of abducens neurons (ABNs) generally ( Mays et al. 1984 ), and lateral rectus (LR) motoneurons (MNs) in particular ( Gamlin et al. 1989a ), are higher in converged gaze than when convergence is relaxed, whereas LR and medial rectus (MR) muscle forces are slightly lower ( Miller et al. 2002 ).

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

Advanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Synergistic convergence and split pons in horizontal gaze palsy and progressive scoliosis in two sisters

Indian Journal of Ophthalmology, 2011
Synergistic convergence is an ocular motor anomaly where on attempted abduction or on attempted horizontal gaze, both the eyes converge. It has been related to peripheral causes such as congenital fibrosis of extraocular muscles (CFEOM), congenital ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Psychogenic convergence spasm mimicking ocular myasthenia.

European review for medical and pharmacological sciences, 2017
A 14-year-old girl presented with a two-years history of fluctuating convergent strabismus, diplopia, and reading difficulty. She has been previously diagnosed by experienced neurologists as having ocular myasthenia and she had been treated for two years with anticholinesterase inhibitors and immunomodulatory drugs.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...
