Sheet piling is an earth retention and excavation support technique that retains soil, using steel sheet sections with interlocking edges. Sheet piles are installed in sequence to design depth along the planned excavation perimeter or seawall alignment.
Replication (statistics) In engineering, science, and statistics, replication is the repetition of an experimental condition so that the variability associated with the phenomenon can be estimated. ASTM, in standard E1847, defines replication as the repetition of the set of all the treatment combinations to be compared in an experiment.
DNA replication is the process which copies the DNA in a cell. After replication is complete, the cell divides, forming to two identical daughter cells. This process is important for the replacement of damaged or dead cells as well as for the proper formation of gametes needed for fertility.
