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...

openings and closings are words or expressions that speakers use to start or end a dialog. ‘hello’ or ‘hi’ are typical examples of an opening, and ‘goodbye’ or ‘bye’ represent a usual closing. some expressions like ‘happy birthday’ or ‘merry new year’ are of other examples which function as opening or ending words. the corpus of this study included six textbooks for teaching persian to non-pers...

We propose a comprehensive theory for the morphological bounds on order-statistics filters (and their repeated iterations). Conditions are derived for morphological openings and closings to serve as bounds (lower and upper, respectively) on order-statistics filters (and their repeated iterations). Under various assumptions, morphological open-closings and close-openings are also shown to serve ...

We report a case of multiple fistulae in ano [8 external openings] in a 45-yrs-old man, who had a history of episodes of pain and pus discharge from openings around the anus since 4 years. Biopsy from the tract of one of the fistula confirmed tubercular infection. He underwent radiofrequency fistulotomy using a Ellman radiofrequency device along with anti-tubercular treatment, which resulted in...
