Effects of co-surfactant and conditioning agent on colour [PDF]

open access: yes, 2015
The colour-fading of hair treated with oxidative dyes is attributed to the effects of ultraviolet light and other environmental factors, but mostly it occurs during shampooing. This effect is caused by the diffusion of chromaphores from within the cortex

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

open access: yesIndian 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 ...

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators

open access: yesAdvanced Engineering Materials, EarlyView.
Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design
