Friction in metal-on-metal total disc arthroplasty: effect of ball radius [PDF]

, 2012
Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.

Prospect for pico-hydropower generation from 3D printed Polyethylene Terephthalate Glycol (PETG) Polymer: A Case Study in Pusu River, Malaysia

Case Studies in Chemical and Environmental Engineering
In Malaysia, rural communities rely on fossil fuel-powered generators for electrification. A small-scale Archimedean Screw Turbine (AST) can be utilized to generate pico-hydropower for potential clean energy generation.

Behavior of Reinforced Concrete Box Beam Strengthened with CFRP U-Wrap Strips Under Torsion

MATEC Web of Conferences, 2016
The present study focuses on the torsional strengthening behavior of reinforced concrete (RC) box section beams that are widely used in bridges. Four RC box beams were fabricated, and three of them were wrapped by carbon fiber-reinforced polymer (CFRP) U-
