Dynamic Margin of Stability During Walking Differs Between End-Stage Hip, Knee, and Ankle Arthritis. [PDF]

J Orthop Res
ABSTRACT End‐stage arthritis of the hip, knee, or ankle leads to differential gait adaptations, but the differences in gait stability remain poorly understood. This study examined whether dynamic gait stability differed between patients with end‐stage hip arthritis (HA), knee arthritis (KA) and ankle arthritis (AA), and matched healthy controls (HC ...

Shielding Properties of Some Marble Types: A Comprehensive Study of Experimental and XCOM Results [PDF]

Materials, 2021
In this work, some marble types were collected from Egypt, and their shielding characteristics were estimated. Their rigidity, in addition to their elegant shape, led us to consider their use as a protective shield, in addition to making the workplace more beautiful.
