Abstract: A method for determining a consistency coefficient of a power-law cement grout includes: determining a water-cement ratio of the power-law cement grout; according to engineering practice requirements, determining a time required to determine the consistency coefficient of the power-law cement grout; and obtaining the consistency coefficient of the power-law cement grout. 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: The present invention discloses a low power dissipation Bluetooth mesh network system and a communication method thereof. The Bluetooth mesh network system includes a friend node and a lower power node. The friend node operates as a proxy server terminal to perform a proxy server broadcast. The lower power node operates as a proxy client and establishes a connection with the friend node based on a proxy protocol when the proxy server broadcast is received and identified. The friend node further filters out an invalid packet unrelated to the low power node and stores a valid packet related to the low power node so as to transmit the valid packet to the low power node when the low power node switches from a sleep status to a wakeup status.

Abstract: An electronic computing device, a method for adjusting the trigger mechanism of a garbage collection function, and a non-transitory computer readable storage medium thereof are provided. A storage unit of the electronic computing device stores a whitelist. The whitelist records a plurality of data sets, wherein each of the data sets has a name of an application and an offset value of the application. A processor of the electronic computing device executes a system program. The system program loads the whitelist into a memory during a initialization procedure. The system program detects that a specific application is triggered and retrieves the offset value of the specific application from the whitelist in the memory according to the name of the specific application. The system program forks a process to the specific application and updates a threshold of a garbage collection function according to the offset value.

Abstract: Antigens are provided which are derived from the enterically transmitted non-A/non-B viral hepatitis agent, known as hepatitis E virus (HEV). The HEV antigens and in particular, soluble species of the capsid protein encoded by the carboxy terminal region of HEV ORF2, are immunoreactive with sera from individuals infected with HEV. In one embodiment, these antigens may be produced by a baculovirus expression vector and form virus-like particles (VLPs). The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The antigens are also useful in vaccine compositions effective in methods for preventing HEV infection.

Abstract: Antigens are provided which are derived from the enterically transmitted non-A/non-B viral hepatitis agent, known as hepatitis E virus (HEV). The HEV antigens and in particular, a soluble 62 kDa species of the capsid protein encoded by ORF2, are immunoreactive with sera from individuals infected with HEV. The 62K antigen may be produced by a baculovirus expression vector and forms virus-like particles (VLPs). The antigens are useful as diagnostic reagents in diagnostic methods and kits for determining infection of an individual with HEV. The antigens are also useful in vaccine compositions effective in methods for preventing HEV infection.
