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.
The purpose of replication is to conserve the entire genome for next generation. The purpose of transcription is to make RNA copies of individual genes that the cell can use in the biochemistry.
