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 ...

First evaluation of a heteroepitaxial diamond ionization chamber operating at low voltage for diagnostic X-ray dosimetry. [PDF]

Med Phys
Abstract Background Heteroepitaxial diamond has recently gained attention as a radiation detector material due to its wide bandgap, radiation hardness, and near‐tissue equivalence. Despite these advantages, its use as a solid‐state ionization chamber for diagnostic X‐ray dosimetry has not yet been established.

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.

Analysis of the radiation parameters of pumice constituent compounds using XCOM

Journal of Physics: Conference Series, 2021
Abstract In this study, analysis of radiation parameters (linear attenuation coefficient, mean free path and half value layer) of pumice constituent compounds was carried out. Analyzes were done on the compounds of Al2O3, Fe2O3, SiO2, CaO, K2O and Na2O with a theoretical approach using the XCOM program for gamma photon energies 57Co (0 ...
