Most patients find that the numbness from the injection wears off after about an hour.
We took our cat to the vet's for its annual cat flu injection.
Time-dependent characterization of the output radiation in a far-field zone was obtained for both free-running and injection-controlled operation with an unstable resonator 1 cavity.
Injection volumes were estimated by measurement of the displacement of cytoplasm after an injection at a controlled pressure.
As a check for potential peripheral effects of curare, the experimental duration of temporal resolution experiments before and after injection were compared.
