This is a partial list of text and image duplicating processes used in business and government from the Industrial Revolution forward. Some are mechanical and some are chemical. Some are mechanical and some are chemical.
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.
Duplicating machines, machines and processes designed to reproduce printed material, photocopying being among the best-known today; see also List of duplicating processes Loop bin duplicator , a device designed to copy pre-recorded audio tapes
In engineering, science, and statistics, replication is the process of repeating a study or experiment under the same or similar conditions to support the original claim, which is crucial to confirm the accuracy of results as well as for identifying and correcting the flaws in the original experiment. [1]
This process results in a build-up of twists in the DNA ahead. [41] This build-up creates a torsional load that would eventually stop the replication fork. Topoisomerases are enzymes that temporarily break the strands of DNA, relieving the tension caused by unwinding the two strands of the DNA helix; topoisomerases (including DNA gyrase ...
The process of duplicating DNA is called DNA replication, and it takes place by first unwinding the duplex DNA molecule, starting at many locations called DNA replication origins, followed by an unzipping process that unwinds the DNA as it is being copied. However, replication does not start at all the different origins at once.
Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners , laser printers , and photocopiers , but for many years they were the primary means of reproducing documents for limited-run distribution.
A mimeograph machine (often abbreviated to mimeo, sometimes called a stencil duplicator or stencil machine) was a low-cost duplicating machine that worked by forcing ink through a stencil onto paper. [1] The process was called mimeography, and a copy made by the process was a mimeograph.
