  • Patent number: 11511220
    Abstract: This invention concerns ultra-high purity, ultra-high performance biogenic silica filtration products comprising diatomaceous earth. In particular, it relates to products comprising diatomaceous earth which is derived from ores that have been specifically selected for their naturally low centrifuged wet density and which have been intensively beneficiated to reduce extractable impurities to near or below detection limits. The low centrifuged wet density of the selected natural ore is either maintained or further reduced through the beneficiation process, which provides for filtration product/media with high particulate holding capacities able to provide for extended filtration cycle times.

  • Publication number: 20220342541
    Abstract: A storage system includes a management node and a plurality of storage nodes forming a redundant array of independent disks (RAID). When the management node determines that not all data in an entire stripe is updated based on a received write request, the management node sends update data chunk obtained from to-be-written data to corresponding storage node. The storage node do not directly update, based on the received update data chunks, data block stored in storage device of the storage node, but store the update data chunk into non-volatile memories (NVM) cache of the storage node and send the update data chunk to another storage node to backup. According to the data updating method, write amplification problems caused in a stripe update process can be reduced, thereby improving update performance of the storage system.

  • Patent number: 11475093
    Abstract: The present application provides a method and an apparatus for processing webpage, a device and storage medium, involving the terminal vision technology. The specific implementation is: when a server determines that a current network meets a preset condition and a webpage to be displayed includes an image required to be displayed, the server sends a static data resource corresponding to the image required to be displayed to the terminal. The preset condition includes at least one of the following: the current network being a mobile network, a bandwidth of the current network being less than a preset bandwidth, and a rate of the current network being less than a preset rate. Therefore, it is unnecessary to send a static data resource corresponding to an image not required to be displayed to the terminal, thereby reducing a traffic consumption and at the meanwhile, improving an integrity and coherence of the webpage.
