چکیده

The behavior of adventitious bacteria during an acidulocomposting process was quantitatively analyzed in garbage-free trials. The numbers of the added Bacillus subtilis and Pseudomonas putida cells diminished in a first-order manner with t(1/2) values of 0.45d and 0.79d, respectively, consistent with the observed stability of the acidulocomposting function.

The Influence of HH Type Steel Microstructure on the Distortion Behavior of Grate Bar Part in the Indurating Machine of Pelletizing Plant

Grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. Steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °C) during the normal operation of the process. In this study, different samples from several sections ofused grate bars with apparent ...
