Since the supremum and infimum of an unbounded set of real numbers may not exist ( the reals are not a complete lattice ), it is convenient to consider sequences in the affinely extended real number system: we add the positive and negative infinities to the real line to give the complete totally ordered set, which is a complete lattice.

Since presently-available DNA sequencing technologies are ill-suited for reading long sequences, large pieces of DNA ( such as genomes ) are often sequenced by ( 1 ) cutting the DNA into small pieces, ( 2 ) reading the small fragments, and ( 3 ) reconstituting the original DNA by merging the information on various fragment.

Since S is non-empty, there is a rational number L such that L < s for some s in S. Now define sequences of rationals ( u < sub > n </ sub >) and ( l < sub > n </ sub >) as follows:

Since it is possible to find sequences of 76 consecutive integers such that each inner member shares a factor with either the first or the last member, 76 is an Erdős – Woods number.

Beginning in 1992, data were published that reported sequences of genes belonging to the Crenarchaea in marine environments .< sup >,</ sup > Since then analysis of the abundant lipids from the membranes of Crenarchaea taken from the open ocean have been used to determine the concentration of these “ low temperature Crenarchaea ” ( See TEX-86 ).

Since it is possible to find sequences of 86 consecutive integers such that each inner member member shares a factor with either the first or the last member, 86 is an Erdős – Woods number.

Since the obvious is not always true, the Republican National Committee wisely analyzed its defeat of last autumn and finds that it occurred, as suspected, in the larger cities.

Since faculty see themselves as self-employed professionals rather than as employees, enthusiasm in a common enterprise is proportionate to the sense of ownership they have in it by virtue of sharing in the decisions that govern its course.

Since C is rational, this correspondence has K coincidences, each of which implies a line of the pencil which meets its image.

Since a ruled surface of order N with N concurrent generators is necessarily a cone, it follows finally that every line through a point, P, of **zg meets its image at P, as asserted.

Since the mid 1950s, when urethane foam first made its appearance in the American market, growth has been little short of fantastic.

Since the land he desired lay within the great northern empire of the Hudson's Bay Company, he purchased great blocks of the Comany's stock with the view to controlling its policies.

Since the constitution forbids introduction of a tax bill at a fiscal session, the administration will either have to cut down expenses or inflate its estimates of anticipated revenues.

Since the railroad cannot reduce the salary of individual union members under contract, it must accomplish its payroll reduction by placing some of the men on furlough, a B. & O. spokesman said.

Since its independence, Armenia has maintained a policy of complementarism by trying to have friendly relations both with Iran, Russia, and the West, including the United States and Europe.

Since this picture was first developed by Ernst Stueckelberg, and acquired its modern form in Feynman's work, it is called the Feynman-Stueckelberg interpretation of antiparticles to honor both scientists.

Since its immense popularity and iconic nature, " grace " and the meaning behind the words of " Amazing Grace " have become as individual as the singer or listener.

Since the activity of antibacterials depends frequently on its concentration, in vitro characterization of antibacterial activity commonly includes the determination of the minimum inhibitory concentration and minimum bactericidal concentration of an antibacterial.
