The method is accurate and reliable, requires less calculation, etc.; and has very high practical value and popularization value in environmental protection and ecological restoration.

Abstract: A method for determining a three-dimensional tortuosity of a loose and broken rock-soil mass, includes the following steps: a particle grading curve of the loose and broken rock-soil mass is obtained by utilizing a particle size analysis, and followed by calculating an equivalent particle size and an average particle size; a porosity of the loose and broken rock-soil mass is obtained by utilizing a moisture content test, a density test, and a specific gravity test; the three-dimensional tortuosity of the loose and broken rock-soil mass is obtained by utilizing the equivalent particle size, the average particle size and the porosity of the loose and broken rock-soil mass. The method has the advantages of simple logic, accuracy and reliability, simple and fast parameter determination, and has high practical value and promotion value in the field of environmental protection and ecological restoration technology.

Abstract: A method for performing ONU Management and Control Interface (OMCI) synchronization includes receiving an OMCI message containing a OLT-G entity identifying OLT's vendor identification (ID) and version. The method also includes determining if an OLT vendor identification (ID) matches with a current vendor ID and if an Optical Line Terminal (OLT) version is compatible with current OMCI handlers. When the OLT vendor ID fails to match with the current vendor ID, automatically performing a OMCI handler switching process. The OMCI handler switching process includes setting a current OLT vendor as a new OLT vendor ID, deleting a OMCI configuration previously stored in the flash memory after setting the new OLT vendor ID, and rebooting the ONT to allow the ONT to initialize a OMCI configuration using a new OMCI profile.

Abstract: An external fluidic system and methods of operating the same are provided. The fluidic system can be hot-swap connected to a flow-cytometer-based system at runtime to expand sheath or waste fluid storage capability of the flow-cytometer-based system by making only minimal changes to the flow-cytometer-based system. The external fluidic system can include a pump and a controller configured to operate the external fluidic system such that the sheath fluid is supplied from the external fluidic system to the flow-cytometer-based system or the waste fluid is extracted from the flow-cytometer-teased system and provided to the external fluidic system.

Abstract: A medium for culturing Balantidium ctenopharyngodoni in vitro, method for preparing the medium and method for culture in vitro are provided, which belongs to technical field of in vitro culture of intestinal protozoa. The formulation of the culture medium includes: 100 ml of Ringer's solution, 0.5 g of yeast extract, 1.0 g of proteose peptone, 3-6 ml of fetal bovine serum, 6-10 ml of horse serum, 300-500 ?l of Bacillus licheniformis suspension, 200-300 mg of aseptic starch. Culture steps include: inoculating collected Balantidium ctenopharyngodoni into a prepared medium, filling with nitrogen and sealing, culturing at 15° C. for 48-72 hours, then transferring to another fresh medium, cycling back and forth, proliferating the Balantidium ctenopharyngodoni continuously. Balantidium ctenopharyngodoni are capable of achieving cell division and proliferation in the culture medium, and lays foundation for the physiological and experimental ecology research of the Balantidium ctenopharyngodoni.

Abstract: A process for configuring an optical network termination (ONT) includes receiving an upstream overhead physical layer operation administration and maintenance (PLOAM) message from an optical line terminal (OLT). The process also includes extracting byte 10 data from the upstream overhead PLOAM message to identify a transceiver type of the OLT, and matching the transceiver type of the OLT with one of a plurality of sets of optical parameters. The process further includes storing the matched transceiver type of the OLT in a double date rate (DDR) memory prior to completing a ranging process with the OLT.
