The geochemistry and mineralogy profiles of the spherules are identical to rock found in southern Quebec, where Sharma and his colleagues argue the impact took place.
With crystallization temperatures in the range of 175 ~ 183[degrees]C, the morphology changed to mixed type birefringent spherules coexisting with boundary crystals for pCBT/PCL blend.
Moreover, industrial spherules may contaminate the natural glasses, both at the outcrop and during laboratory treatments [3-5].
In some cases the transition from the fine baculi to thicker, aggregated baculi can be observed: the apatitic spherules cover the fine baculi and form their granular surface (Fig.
volubilis was described by Tryon and Lugardon (1991) as papillate-rugulate, with scattered spherules on the surface and in section with a plain exospore and a laminate perispore.
A particularly high degree of bound water, due to water not only being bound onto the surface but additionally in the inner volumes of the hollow spherules of allophanes, has been discussed for aliophanic materials (Regalado et al.
A transbronchial fine needle aspirate of a subcarinal lymph node demonstrated lymphoid tissue with a granuloma and rare intracellular spherules subsequently identified as Coccidioidis immitis.
The large spherules (10-80 mcm) are easily seen under microscopy, typically as granulomatous or suppurative inflammatory infiltrate.
Rapid reacting components that precipitate fine mesophase spherules under mild pyrolytic conditions undergo coalescence without appreciable growth to yield fine isotropic micro-constituents that are not readily deformed;
These authors suggested that these metal-rich spherules would be made of complexed metallothionein-like proteins and would explain the high concentrations of Cu within the digestive gland.
At higher magnification, the polysomatic nuclei (PN) of the gastric diverticula are strongly basophilic, as are many of the small droplets and varying sizes of spherules shown in Fig.
