european corn borer, ostrinia nubilalis hb. is a polyphagous insect, recognizing world widely as the predominant pest of maize. in this research the relative resistance of eleven hybrids of maize was evaluated in a field in agricultural and natural resources research center of moghan. this experiment was conducted in three replicates in a complete randomized block design. for comparison of the ...

This paper describes a two-dimensional computer simulation study of the impact induced breakage of brittle solid particles. The work started as an attempt to understand the effect of impact velocity on the induced breakage and in particular to explain why there is a shift in the slope of the size distribution at large impact velocities. The results indicate that the observed breakage pattern is...

in this study the wavelet neural network (wnn) and artificial neural network (ann) were used to simulate barley breakage percentage in combine harvester. the models have been trained using the same data conditions. air temperature, thresher cylinder speed, distance between thresher cylinder and concave (back and forth) and the percentage of barely moisture were as the input variables. the resul...

Within the B̃ absorption band of CH(2)BrCl, we theoretically analyze the laser-induced control of the Br/Cl branching ratio, Br + CH(2)Cl ← CH(2)BrCl → CH(2)Br + Cl, with CH(2)BrCl initially in its vibrational ground state. For weak-field excitation, the Br/Cl branching ratio increases as a function of wavelength, however, for wavelengths below 180 nm the branching ratio cannot be made smaller t...

Functional properties of fermented bran produced by Aspergillus oryzae and Rhizopus sp. in a solid-state fermentation system were determined, with an aim to evaluate their application in food formulation. The defatted rice bran and wheat bran were inoculated with the spores of the cultures and incubated at 30°C for 72 h. Samples were withdrawn at 0, 24, 48 and 72 h. Protein content, protein sol...

Twin screw wet granulation (TSG) is gaining more attention and becoming an important process in the pharmaceutical industry. The process is widely implemented because of its flexibility, short residence time, and small equipment footprint. Past studies have shown that screw elements can have a significant impact on the performance of the TSG process. In addition, these studies identified that b...
