The municipal sewage sludge typically has very high water content and low shear strength.Conventional methods of lime and cement solidification of municipal sewage sludge often suffer high cost, significant drying shrinkage, frequent cracking, high hydraulic conductivity, and low strength.To overcome these shortcomings, in this paper a skeleton-bui

Confluent canals are potentially dangerous for endodontic rotary instruments because they are rarely detected with periapical radiographs and they usually create an abrupt curvature, with a small radius less than two millimeters and a high degree of the curvature close up Hair Ties to 90 degree.The purpose of this clinical article is to show first
Certain quantum Treats devices, such as half-wave plates and quarter-wave plates in quantum optics, are bidirectional, meaning that the roles of their input and output ports can be exchanged.Bidirectional devices can be used in a forward mode and a backward mode, corresponding to two opposite choices of the input-output direction.They can also be u
