Coming into usage in 1990, the Western term lean manufacturing (lean enterprise, lean production, or simply "lean") refers to a business idea that considered the expenditure of resources for anything other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Today the Lean concept is broadening to ...
Elimination can fail as a strategy if the hazardous process or material is reintroduced at a later stage in the design or production phases. [6] The complete elimination of hazards is a major component to the philosophy of Prevention through Design, which promotes the practice of eliminating hazards at the earliest design stages of a project.

Elimination theory culminated with the work of Leopold Kronecker, and finally Macaulay, who introduced multivariate resultants and U-resultants, providing complete elimination methods for systems of polynomial equations, which are described in the chapter on Elimination theory in the first editions (1930) of van der Waerden's Moderne Algebra.
More generally, Zaytsev's rule predicts that in an elimination reaction the most substituted product will be the most stable, and therefore the most favored. The rule makes no generalizations about the stereochemistry of the newly formed alkene, but only the regiochemistry of the elimination reaction. While effective at predicting the favored ...
In organic chemistry, the E i mechanism (Elimination Internal/Intramolecular), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in a syn elimination.

The Elimination is an autobiographical account of Rithy Panh's survival during the Pol Pot regime. It was co-written with novelist Christophe Bataille and published in 2011 by Grasset Publishing. This book is also an essay and report that documents the one-on-one conversations between Rithy Panh and Duch, a former Khmer Rouge officer. [1]
Radicals can undergo a disproportionation reaction through a radical elimination mechanism (See Fig. 1). Here a radical abstracts a hydrogen atom from another same radical to form two non-radical species: an alkane and an alkene. Radicals can also undergo an elimination reaction to generate a new radical as the leaving group.
The Convention on the Elimination of all Forms of Discrimination Against Women (CEDAW) is an international treaty adopted in 1979 by the United Nations General Assembly. Described as an international bill of rights for women , it was instituted on 3 September 1981 and has been ratified by 189 states. [ 1 ]
