In this study, the performance and the useful Pool Slides life of a mixed ceramic tool with S-type edge microgeometry are evaluated for the case of dry turning of AISI 4140 steel hardened to 55 HRC.The influence of the cutting speed and feed rate of the cutting parameters on the tool failure was investigated.The experiments were designed and analys
Bridge collapse events are common in major earthquakes around the world, among which continuous girder bridges are the most involved.In order to explore the collapse mechanism of a continuous girder bridge in an earthquake, the collapse mode of a two-span continuous girder bridge specimen which had been studied by the shaking table test was analyze
We propose a simple scheme to compress an electron beam with an optical laser, which can potentially Can Sleeve achieve a bunch length much shorter than what is currently available with a conventional radio-frequency technique.Instead of an energy chirp, the optical laser induces an energy modulation whose amplitude linearly changes along the longi
Ocean boundary current systems 30" Swivel Barstool are key components of the climate system, are home to highly productive ecosystems, and have numerous societal impacts.Establishment of a global network of boundary current observing systems is a critical part of ongoing development of the Global Ocean Observing System.The characteristics of bounda
The primary Waste Heat Boiler (WHB) in an ammonia plant experienced cap leaking and the outer tube rupture after ten months since 30" Swivel Barstool the last repair and replacement (total retubing).The leaking cap and the outer tube materials are low carbon steel SA-204 Gr.B and SA-209 Gr.T1a.The inappropriate vertical part of the leaked cap, whic
