A Rare Incidence of Breakage of tip of Micropituitary Forceps during Percutaneous Discectomy - How to Remove it: A Case Report [PDF]

open access: yesMalaysian Orthopaedic Journal, 2015
Breakage of the tip of the micropituitary forceps during spine surgery is a rare occurrence. Retrieval of the broken tip could be a challenge in minimally invasive surgeries due to limitation of access and retrieval instruments.

Halation in image intensifiers [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1992
Halation effects in microchannel plate intensifiers are discussed. It is shown that infilling of line profiles observed in absorption-line spectra taken with four-stage magnetically focused intensifiers cannot be explained by such a mechanism; it is suggested that slow phosphor decay may instead be a cause of the ...
