A canola cultivar designated 45A54, plants and seeds of the 45A54 canola cultivar, methods for producing a canola plant produced by crossing the 45A54 cultivar with itself or with another canola plant, and hybrid canola seeds and plants produced by crossing the 45A54 cultivar with another canola line or plant are provided. The syringe assembly further includes a stopper disposed within a chamber of the syringe barrel, a plunger adapter engaged with the stopper, and a plunger rod having first and second ends. Furthermore, in at least one of the pulse sequences, there are not less than two phases alternating. Therefore, this heating blower can discharge nanometer-size ion mist to the outside without replenishment of water. The laser resonator system uses the Offner relay system for optimal transmission of the laser beam between the two gain media.
