“SYRI” – A hands-on teaching model for SYRInging of nasolacrimal duct

Indian Journal of Ophthalmology
Background: Nasolacrimal duct (NLD) screening is a standard before cataract surgery. Lacrimal sac pressure and syringing rules out NLD obstructions.[1] However, lacrimal syringing is invasive and risks iatrogenic injury to the lacrimal drainage system ...

Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
