Inverse parallel SCRs can also be used in place of the triac ; because each SCR in the pair has an entire half-cycle of reverse polarity applied to it, the SCRs, unlike TRIACs, are sure to turn off.

Inverse semigroups appear in a range of contexts ; for

Each cell except the last in the chain also contains the address of the Y-cell that is the next element of the chain ; ;

Hence it is the atomic number alone that determines the chemical properties of an element ; and it is for this reason that an element can be defined as consisting of any mixture of atoms with a given atomic number.

The red bars mark the pivot element ; at the start of the animation, the element farthest to the right hand side is chosen as the pivot.

This is not the most general situation of a Cartesian product of a family of sets, where a same set can occur more than once as a factor ; however, one can focus on elements of such a product that select the same element every time a given set appears as factor, and such elements correspond to an element of the Cartesian product of all distinct sets in the family.

In the even simpler case of a collection of one set, a choice function just corresponds to an element, so this instance of the axiom of choice says that every nonempty set has an element ; this holds trivially.

Antimony ( or ; ) is a toxic chemical element with symbol Sb and atomic number 51.

This led to americium being located right below its twin lanthanide element europium ; it was thus by analogy named after another continent, America: " The name americium ( after the Americas ) and the symbol Am are suggested for the element on the basis of its position as the sixth member of the actinide rare-earth series, analogous to europium, Eu, of the lanthanide series.

Astatine is an extremely radioactive element ; all its isotopes have half-lives of less than 12 hours, decaying into bismuth, polonium, radon, or other astatine isotopes.

For each element a of a group G, conjugation by a is the operation φ < sub > a </ sub >: G → G given by ( or a < sup >− 1 </ sup > ga ; usage varies ).

Allotropes are different structural modifications of an element ; the atoms of the element are bonded together in a different manner.

For this reason, the C programming language specifies that array indices always begin at 0 ; and many programmers will call that element " zeroth " rather than " first ".

All but one of the actinides are f-block elements, corresponding to the filling of the 5f electron shell ; lawrencium, a d-block element, is also generally considered an actinide.

Scarlatti's style, however, is more than a transitional element in Western music ; like most of his Naples colleagues he shows an almost modern understanding of the psychology of modulation and also frequently makes use of the ever-changing phrase lengths so typical of the Napoli school.

The advantage of this technique is that only a medium-resolution monochromator is necessary for measuring AAS ; however, it has the disadvantage that usually a separate lamp is required for each element that has to be determined.

The relatively small number of atomic absorption lines ( compared to atomic emission lines ) and their narrow width ( a few pm ) make spectral overlap rare ; there are only very few examples known that an absorption line from one element will overlap with another.

; Identity element: There exists an element e in A, such that for all elements a in A, the equation holds.
