Photon asymmetry of the g p -> pi+ n reaction in the region of the D(1232) resonance
… photons with coherent peak energies of 400 and 440 MeV, corresponding to the upper region of the Delta(1232) resonance. The measurements show the energy and angular dependence of Sigma over the range 30 degrees < theta(pi+) < 170 degrees in the Centre of Mass frame in five bins of varying width. …

Analysis of Heat Transfer Fouling by Thin Stillage From Dry Grind Corn Processing Facilities
… Reynolds number (Re) on fouling. Tests at Re = 440 had shorter induction periods and faster fouling rates than tests at Re = 880. Protein contents of fouling deposits from tests at both Re were similar, but ash contents of fouling deposits from tests at Re = 440 were less than ash contents from …
