Teachers can further set assignment-analysis options so that students can review the system's "originality reports" before they finalize their submission. A peer-review option is also available. Some virtual learning environments can be configured to support Turnitin, so that student assignments can be automatically submitted for analysis.
Systems for text similarity detection implement one of two generic detection approaches, one being external, the other being intrinsic. [5] External detection systems compare a suspicious document with a reference collection, which is a set of documents assumed to be genuine. [6]
Originality: The tests and research done must present something new to the scientific community. Detachment: The scientists' reasons for practicing this science must be simply for the expansion of their knowledge. The scientists should not have personal reasons to expect certain results.
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Originality is the aspect of created or invented works that distinguish them from reproductions, clones, forgeries, or substantially derivative works. [citation needed] The modern idea of originality is according to some scholars tied to Romanticism, [1] by a notion that is often called romantic originality.
Importance: First major text on polymer chemistry; presents both organic and physical chemistry aspects. Written by a chemist who made major contributions to the physical chemistry of polymers, for which he won the Nobel prize in 1974.
In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.
Frederick Sanger. In 1945, Frederick Sanger described its use for determining the N-terminal amino acid in polypeptide chains, in particular insulin. [4] Sanger's initial results suggested that insulin was a smaller molecule than previously estimated (molecular weight 12,000), and that it consisted of four chains (two ending in glycine and two ending in phenylalanine), with the chains cross ...
