The principal difference in crystal structure between polyps from the two different water depths was that acicular
crystals of samples from 9 m were much more finely structured and appeared to have a higher porosity than their counterparts from the reef flat.
Median parapodia with superior notopodial ligule digitate, inferior ligule blunt, longer than wide, acicular
neuropodial ligule wider than long, slightly triangular, inferior ligule longer than wide (Fig.
In addition to the ultrathin coating, the Nano Cubic system incorporates two types of extremely fine magnetic particles: acicular
ferromagnetic alloy particles and tabular ferromagnetic hexagonal barium ferrite particles.
Discrete multistate character 12 (leaf shape in cross-section) was treated as additive, because a direct transformation series was hypothesized for it following the semophyletic evolutionary sequence suggested by Bocher (1979) from planate leaf blade, to boat shaped, to acicular
by marked involution.
To the best of our knowledge, the use of acicular
precipitated calcium carbonate as whisker is not reported in technical literature.
7, revealed a greater presence of grain boundary ferrite (GBF) and acicular
ferrite (AF) at the fusion zone in (b), (c) and (d).
Massive azurite is found with acicular
malachite in one of the upper workings (7th level) of the Reward mine.
1 mm thick near the base, thinly coriaceous mainly toward the base, suberect-arcuate, slightly channeled, dark green to slightly bronze colored, abaxially densely and coarsely white-lepidote with trichomes obscuring the color of the blade, finely nerved, adaxially subdensely white lepidote only at the base and glabrous toward the apex, apex long attenuate-caudate; margins laxly spinose, spines narrowly triangular, acicular
and pale castaneous toward the apex, 0.5-1.5 mm long, 0.5-1 mm wide at base, 6-11 mm apart, slightly to distinctly antrorse-uncinate.
Hypoeutectic cast Al-Si alloys are highly susceptible to occurrence of the sharp edges of the coarse acicular
silicon phase that promote crack initiation, and propagation in alloys and also the porosity formation
Added into a liquid Al-Si alloy, STRONAL 9010 modifies the structure of the eutectic silicon and induces the structure to change the silicon morphology from acicular
lamellar to uniform and globular.
Another important difference with this sabellid previously reported habiting abalone shells is the shape of the abdominal uncini, in Oriopsis are rasp-shaped plates, without main fang, defining a clear difference with the abdominal uncini acicular
with a single main tooth crowned with shorter series of teeth, characteristic of T.
In the other case precipitation of high amount of acicular
carbide phase occurred at the seam-base boundary in the process of subsequent heat treatment, whereby width of the diffusion zone increased up to 30-50 [micro]m and more.
