Abstract: A fluidized solidified soil based on gold tailings includes the following raw materials in parts by mass: 75 parts to 80 parts of gold tailings, 5.2 parts to 13 parts of a dispersant solution, and 9 parts to 16 parts of a solidifying material. A preparation method includes the following steps: mixing the gold tailings with the dispersant solution, and then stirring to obtain a suspension slurry of the gold tailings; and adding the solidifying material, and stirring to obtain the fluidized solidified soil. In the present disclosure, the gold tailings are used as a main material, combined with a special dispersant solution and a special solidifying material, and a fluidized solidified soil is prepared with fluidity suitable for pumping and a certain strength after hardening. The fluidized solidified soil prevents the pollution caused by gold tailings landfilling, and can be used as a filling material for various construction projects.

Abstract: A wireless mesh access point receives a first notification of firmware download availability. In response to the first notification, the wireless mesh access point downloads a firmware file from a peer from which the first notification was received. The wireless mesh access point loads the downloaded firmware file into a firmware memory associated with operation of a processor. The wireless mesh access point then transmits a second notification of firmware download availability to one or more other peers.
