At 136 pages, the pocket-sized fifth edition of the National Association of Elevator Contractors’ (NAEC) Field Employees’ Elevator Testing Manual is not even a quarter of the length of the American Society of Mechanical Engineers (ASME) A17.2-2020 Guide for Inspection of Elevators, Escalators and Moving Walks.

In December 2024, I had the opportunity to visit the National Elevator Industry Educational Program’s Training Center in Warwick, Rhode Island. As I walked into the area that houses welding booths, I was pleased to see a sticky mat at the entrance to the area. It has been a while since I had seen one of those outside an elevator machine room door, back when motor-generator sets were the norm, and we were all afraid of tracking carbon dust across a customer’s carpeted floors.

Multiwalled carbon nanotubes (MWCNTs) have been widely used in many disciplines and raised great concerns about their negative health impacts, especially environmental and occupational exposure. MWCNTs have been reported to induce fibrotic responses; however, the underlying mechanisms remain largely veiled. Here, we reported that MWCNTs inhalation induced lung fibrosis together with decreased lung compliance, increased elastance in the mice model, and elevated surface tension in vitro.

AbstractAn optical fiber φ-OFDR shape sensor with a submillimeter spatial resolution of 200 µm was demonstrated by using femtosecond-laser-induced permanent scatter array (PS array) multicore fiber (MCF). A PS array was successfully inscribed in each slightly twisted core of the 400-mm-long MCF.
