Fragmentation analysis is an essential part of the optimization process in any mining operation. The costs loading, hauling, and crushing rock are strongly influenced by size distribution blasted rock. Several direct indirect methods used to analyse or predict fragmentation, but none entirely applicable fragmentation assessment sublevel caving mines, mainly because limitations imposed undergrou...

The aim of this study was to determine the effect of water salinity changes on thyroid hormones level and thyroid-stimulating hormone (TSH) of grass carp. For this purpose 120 grass carp were divided randomly in to four groups (10 fish in each group and three...

The design and analysis of large and complex system requires frequently that the system is divided into smaller units, called sub-systems. The structure of overall system resulting from the interconnections of sub-systems can be very complex. One of the most common structures, is the hierarchical structure, i.e. the lay-out of the structure is vertical. Consequently in this report only hierarch...
