Novel ethylene styrene interpolymers having triads with double reverse styrene incorporation may be prepared in the presence of a transition metal phosphinimine compound and an activator. The assembly includes a first funnel configured for coupling to a breast. Further, the electron beam irradiation device allows cost reduction, because the device allows collective irradiation using a two dimensional pattern. Still further provided by the invention are methods for producing soybean plants by crossing the soybean variety 4440685 with itself or another soybean variety and plants produced by such methods. The hollow member being open to atmospheric pressure, thereby defining a chamber in conjunction with the at least one active portion.
