Associated radioactive mines are widely distributed in China, with many industries, complex processes and technologies, close relationship with the public, and great impact on the radiation environment.They are relatively weak links in nuclear and radiation safety supervision.In the process of implementing the upper level document, some specific pr
An underwater glider equipped with a hydrophone observed the acoustic sounds of an earthquake that occurred on 15 November 2017 05:29:32 (UTC) in the Pohang area.The underwater glider observed the earthquake sounds after 19 s (05:29:51) at approximately 140 km from the Pohang epicenter.In order to distinguish the earthquake sound from the glider
Conventional posterior dynamic stabilization devices demonstrated a tendency towards highly rigid stabilization approximating that of titanium rods in flexion.In extension, they excessively offload the index segment, making the device as the sole load-bearing structure, with concerns Wall Art of device failure.The goal of this study was to compare

Thyreophora is a taxon of dinosaurs composed of Stegosauria and Ankylosauria, whose members have been known to utilise their tails as powerful defensive weapons.Remains of these dinosaurs are scarce; the Portuguese taxon, Miragaia longicollum, known from three individuals, provides precious pieces of information on the anatomy of these rare animals
