Mechanical Characteristics of Male Urethral Catheterization: Simulator and Cadaveric Donor Study
… a better understanding of the catheter insertion mechanical characteristics is needed to develop more realistic simulators for accurate clinical training. A custom-made Catheter Insertion Force Assessment Tool (+/- 0.25N absolute accuracy) and Position Acquisition System were used in male urethral …

Study of mechanical characteristics of ankle-foot orthoses using finite element analysis method
… This is due to lack of understanding of the mechanical characteristics (i.e. stiffness) and stress distribution of AFOs. There is evidence indicating an optimal match exists between AFOs stiffness and successful rehabilitation. To date, most investigations on AFOs to determine mechanical …

The mechanical characteristics and differentiation potential of the axial progenitor region in vertebrate embryos
… notochord, the NMCs, and the PSM are distinct mechanically; with the notochord being the stiffest and the PSM the softest. In addition, I observe an anterior-to-posterior reducing stiffness gradient within the NMC region. These findings are recapitulated with our lab’s custom-built Tissue Force …

A Study on the Mechanical Characteristics of a Fiberglass Bed Formed During a Loss-of-Coolant-Accident at a PWR Nuclear Facility
Following a Loss-of-Coolant-Accident (LOCA) in one of the primary coolant lines in the containment building of a PWR Facility, it is possible that fiberglass pipe insulation could be dislodged and washed down to the sump pool. This fiberglass could collect into a bed' and cause blockage on the sump …
