discharge grates are one of the most important parts of sag mills. these grates prevent balls and unbroken ores from discharging the mill and they have a significant effect on the mill filling and size distribution of the discharge flow. to consider the effect of openings of the grates on the overall efficiency of the comminution operation, the variation of the grates shape and size were closel...

in this study, calcareous nannofossils at the boundary between tirgan and sarcheshmeh formations at taherabad and mozduran sections have been studied. these sections are located in the eastern kopet-dagh basin. 22 nannoplankton species of 14 genera in taherabad section and 20 species of 14 genera in mozduran section were identified. according to the first occurrence of index species and fossil ...

and attendant exposure of the seaport town citizens to benzene emanating from petroleum handled through the terminal as one example, Goldstein reviewed a number of risk assessment issues. He noted that the risk assessment agenda has never been set by scientific experts but is always strongly affected by economic, political, and social issues. He also pointed out that there are two often contrad...

in this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of sarcheshmeh copper complex was studied. the comminution circuit of this plant includes one sag mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. the goal of this work was to calcu...

Previous work in this and other laboratories has shown that penicillin is specifically and irreversibly bound by sensitive bacteria (Pasynskii and Katorskaya, 1947; Cooper and Rowley, 1949; Maass and Johnson, 1949a, 1949b; Rowley et al., 1950). It is thought that this binding is closely related to the primary mode of action of penicillin. Attempts have been made to elucidate the nature of this ...
