Abstract: A method for determining a productivity of a coalbed methane well without shutting down the well includes steps of: obtaining coalbed methane basic data; based on PVT experimental data, determining a relationship table between a pressure and a coalbed methane deviation factor, and a relationship table between the pressure and a pseudo-pressure; recording daily gas production rates, bottomhole flow pressures, and cumulative gas productions at each stabilized flow pressure test moment in at least three different production stages; determining formation pressures corresponding to each stabilized flow pressure test moment based on a material balance equation; according to the formation pressures, the bottomhole flow pressures and the production rates, determining coefficients in a deliverability equation of the coalbed methane well for determining the deliverability equation; substituting the formation pressures and the bottomhole flow pressures into the deliverability equation for obtaining corresponding product

Abstract: The present application discloses a temperature control plate and a Measurement method for the temperature control plate for cold-chain transportation. The temperature control plate for cold-chain transportation comprises a phase-change gel, a vacuum-sealing bag, a sealed plastic box, and an RFID passive temperature sensor tag. The phase-change gel is filled in the vacuum-sealing bag, and a supporting frame is embedded in the phase-change gel. The RFID passive temperature sensor tag is embedded in the phase-change gel. The vacuum-sealing bag is packed in the sealed plastic box, and the sealed plastic box is externally labeled with a tag identifier. The vacuum-sealing bag is a PET vacuum-sealing bag, and the sealed plastic box is a PET sealed plastic box.

Abstract: The present invention provides recombinant monoclonal antibodies that bind to the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2 or COVID-19) spike protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to SARS-CoV-2 spike protein. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing SARS-CoV-2 activity, thus providing a means of treating or preventing COVID-19 infection in humans. In some embodiments, the invention provides for a combination of one or more antibodies that bind to the SARS-CoV-2 spike protein for use in treating COVID-19 infection. In certain embodiments, the one or more antibodies bind to distinct non-competing epitopes comprised in the receptor binding domain of the SARS-CoV-2 spike protein.
