We study pulse propagation in one-dimensional chains of spherical granules decorated with small grains placed between large granules. The effect of the small granules can be captured by replacing the decorated chains by undecorated chains of large granules of appropriately renormalized mass and effective interaction between the large granules. This allows us to obtain simple analytic expression...

Image analysis techniques have been used to investigate the likelihood of being able to classify and assign a probability regarding the plant origin of individual starch granules in a collection of granules. Quantifiable variables were used to characterize the granules, and the assignments and probabilities were calculated objectively. We consider the classification of images containing granule...

In electron microscopic investigations on the proximal tubule of the mouse kidney, large osmiophilic granules in the cytoplasm of the epithelial cells have been found by various authors (2, 13, 14, 20). Rhodin (13) and Clark (2) have pointed out that the granules contain concentric lamellae, but there have been no further investigations on the fine structure of these granules so far. Recently M...

Functionally active mature neutrophile leukocytes, generally are found to contain a few mitochondria, in extremely small number, either by supravital staining with Janus green, or by smear preparation and Altmann's staining process, and even with the electron microscope, a very few mitochondria may be observed. On the other hand, abundant neutrophilic granules may be found in neutrophile leukoc...

The mechanical reliability of products must be assured for scaling up and production complex‐shaped components by spark plasma sintering (SPS) spray‐dried granules. evolution morphologies pores defects, which control the strength, is investigated using synchrotron X‐ray multiscale tomography during SPS alumina granules at 1300 °C. While large defects arising from hierarchical granule packing st...

Knowledge representation realized by information granules is one of the essential facets of granular computing and an area of intensive research. Fuzzy clustering and clustering are general vehicles to realize formation of information granules. Granulation – degranulation paradigm is one of the schemes determining and quantifying functionality and knowledge representation capabilities of inform...

Adrenomedullary chromaffin cells respond to sympathetic nervous system activation by secreting a cocktail of potent neuropeptides and hormones into the circulation. The distinct phases of the chromaffin cell secretory response have been attributed to the progressive fusion of distinct populations of dense core granules with different activation kinetics. However, it has been difficult to define...

We obtained cell preparations containing greater than 95% neutrophils from freshly drawn bovine blood. The cells were suspended in sucrose and disrupted in a Dounce homogenizer, and the postnuclear supernate was fractionated by zonal differential sedimentation and by isopycnic equilibration. The subcellular fractions were characterized biochemically by testing for marker enzymes and other const...

Studies on the formation of ommochrome pigment granules are very few, despite their generalized occurrence as screening pigments in insect eyes. This is particularly true for ommochrome granules responsible for epidermal coloration. The aims of this study were to characterize the localization of major body pigments in a color changing mimetic spider, Misumena vatia (Thomisidae), and to describe...

BACKGROUND Oocyte cortical granules are important in the fertilization of numerous species including mammals. Relatively little is known about the composition, migration, and pre-fertilization release of mammalian oocyte cortical granules. RESULTS Results obtained with confocal scanning laser microscopy indicated that mouse oocytes have at least two populations of cortical granules, one that ...
