The
dodecahedral sound source--one of the newest products of the Danish company "Bruel & Kjaer"--creates standardized constant noise.
(2) Large trapezohedral topazolite or army-green demantoid crystals growing on the end of a small grass-green
dodecahedral demantoid crystal which is elongated along the [111] axis, resulting in a scepter shape.
Remember the vivid rose-pink
dodecahedral crystals of grossular which Benny Fenn recovered in quantity from his diggings in the Sierra de las Cruces range, Coahuila/Chihuahua, in the late 1990s?
These effects are modeled using a
dodecahedral cell.
COMPLEX SOCCER BALL Weeks and his coauthors report that a shape called the Poincare
dodecahedral space is a good fit for both the quadrupole data and estimates of the universe's curvature.
Bornite is fairly common in zone 3 of the lower amygdaloid, occurring as
dodecahedral crystals from 0.5 to 2 mm on albite.
In addition to this, the chosen repetitive unit, e.g., cubic (12, 10), tetrahedral (11), hexagonal (8) or
dodecahedral (5) influences the outcome of the constitutive equation.
It is interesting to note, however, that some of the Alpine crystals may have formed, at least in part, under cooler conditions: some of them show distinct zoning, both in color and habit, grading outward from pink octahedral cores formed at high temperatures to green, purple or colorless, cuboctahedral or
dodecahedral exteriors presumably formed at lower temperatures
