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.
When DNA must make a copy of itself the process is called replication. Replication is important because new cells must have an exact copy of DNA. Enzymes are involved in the replication process. An enzyme can usually be recognized by the ase ending in its name.
