متن کاملAIR PRESSURE SIMULATION IN CASTING MOLDS
During mold filling, molten metal can only advance as quickly as the air inside thecavity is expelled. In this work an analytical model describing air flow is developed based on aincompressible flow theory. Air pressure has serious effects upon the filling behaviour such assurface profile and filling time. In this work a new mathematical model is proposed for calculationthe air pressure during ...

ferent among treatments. Protozoal counts were not different among treatments (P > 0.05) in ruminal or omasal samples. Generic protozoal counts were not different (P > 0.05) among treatments, corresponding with similar banding profiles from DGGE. Multivariate statistics showed no difference (P > 0.05) in generic distribution of protozoa in ruminal vs. omasal samples, supporting absence of selec...
