Archival, formalin-fixed, paraffin-embedded lung or pleural tissue specimens that contained various birefringent
crystals were retrieved from departmental autopsy and surgical pathology files.
Based on this sample power, an analysis was done to score for changes within each of these three generations of respiratory bronchioles from each case for the following histologic features: smooth muscle hypertrophy, fibrosis, alveolar macrophage frequency, degree of inflammatory change within the interstitial wall, amount of carbonaceous pigment within each respiratory bronchiole generation, and the amount of birefringent
dust particles within each of these generations.
2) Injection speed and, to a lesser extent, melt temperature, were significant in producing birefringent
shear zones in the surface of the TPO.
A polarizing lens is useful in this situation, since talc and microcrystalline cellulose (but not crospovidone) are strongly birefringent
(Figure 8, D [inset]) and stand out at low magnification.
JDSU's use of liquid crystal polymer and form birefringent
dielectric thin films delivers a high degree of customization and a large-area format while achieving superior optical flatness.
A significant delay in deliveries of birefringent
CASIX's crystal products include laser crystals, nonlinear crystals, birefringent
crystals, and diode pumped microchip (DPM) crystal assemblies for commercial laser systems, instrument systems, and diode pumped solid state (DPSS) laser module applications.
PDLCs, which in their common form, consist of micrometer-sized, birefringent
LC droplets dispersed in an optically transparent and uniform polymer film (6), represent an important new class of materials for such optical device application (7), (8).
Congo red-stained slides must be examined under polarized light and only the presence of apple-green birefringent
deposits is considered diagnostic of amyloid.
They are made from birefringent
crystals such as quartz, calcite, lithium niobate, and yttrium vanadate, and by combining glass substrates and optical thin films.
CASIX's a-BBO crystals have a large birefringent
coefficient and wide transmission window range from 189 nanometers to 3500 nanometers.
Their work conducted on maleated polyethylene (MAPE)/organoclay extrudates showed a distinct athermal birefringent
pattern for the samples at temperatures substantially greater than the MAPE melting temperature.
