The first in what would become a chain of potential Goldilocks planets, identified in 2007, was a presumably rocky ball about five times as massive as the Earth and orbiting only about seven million miles from Gliese 581, close enough within the small star's shrunken habitable zone to have a warm surface.
Nevertheless, the infinitist would point out that any reason can be legitimately questioned and, thus, the chain of potential reasons is limitless.
We study the transverse net current of particles moving through two-dimensional square arrays or chains of potential energy hills or wells when driven perpendicularly to their spatial symmetry axis (i.e., the mirror-symmetry axis).
Palmitate is selected specifically by PagP, employing a gating mechanism sensitive to the length of hydrocarbon chains of potential donor lipids (Khan et al., 2010).
For example, Lys63 ubiquitin chains have a more-linear configuration, whereas Lys48 chains have a more "closed" configuration, so these two different chain types span a range of potential topologies.
The alarm is to be attached to the key chain of a potential victim, who can press it upon sensing a criminal nearby.
Ferrocenyl surfactants (25 and 26 in Figure 14a) used as intercalants, having different chain lengths, ensured both a range of potentials and a range of possible conformations; as clay, standard Wyoming montmorillonite (SWy-1), of formula (Al2.88Fe0.68Mg0.47)(Si7.7Al0.29)O20(OH)4, was used.
"They told us they weren't believing what they saw" in commercials for value-price haircut chains, Mr. Neary said of potential customers.
Wal-Mart, which has had trouble partnering with vendors to offer health care, wants to expand again in an effort to compete with other retailers and drugstore chains for millions of potential customers insured through the new health care law.
Depending on the makeup of his registry at any moment, Mr. Hil likes to stretch his chains as long as reasonable and then end them if a donor is difficult to match or if one chain is draining others of potential transplants.
We therefore relied on our previously successful approach using gene discovery by cDNA microarray followed by expression validation through polymerase chain reaction (PCR), ranking of potential markers and the development and testing of serum assays.
