Impact damping and vibration attenuation in nematic liquid crystal elastomers
Mohand O. Saed, Waiel Elmadih, Andrew Terentjev, Dimitrios Chronopoulos, David Williamson, Eugene M. Terentjev
Nov 22, 2021
Abstract: Nematic liquid crystal elastomers (LCE) exhibit unique mechanical properties, placing them in a category distinct from other viscoelastic systems. One of their most celebrated properties is the ‘soft elasticity’...
A remarkable case of thyrotoxicosis initially caused by graves’ disease followed by a probable TSHoma – a case report
Abstract: Background: Graves’ disease is the commonest cause of thyrotoxicosis whilst thyrotropin (TSH)-producing pituitary adenomas (thyrotropinomas, TSHomas) are very rare and account for just 1–2% of all pituitary adenomas....
