We examined a series of changes that occur in the trabecular meshwork fibers of human eyes during fetal development at 12-30 weeks of gestation. At 12 and 15 weeks, the uveal meshwork was stained black with silver impregnation (indicating the predominance of collagen types III and IV) in the endomysium of the ciliary muscle. At 20 weeks, in combination with Schlemm's canal, a dense fibrous tiss...

La& Atsirtant Drmanstrotw of Anatomy, in thc Mrdical Drpartmtnt of tht Univrrri/y of Michigan. By far the greater number of all the communications dealing with the ending of nerves in muscle tissues pertain to observations made on muscle tissue impregnated with one or the other of the several gold chloride methods; valuable as such observations have been, they yet leave many of the details more...

To prepare structural colored fibers by a cholesteric liquid crystal (CLC), cellulose derivatives forming CLC structure under room condition were synthesized through the esterification of hydroxypropyl (HPC) with propionic an hydride. Obtained formed conditions within degree acid (PA) from 0.83 to 1.1 per glucose unit. It was also possible mold film shape or fiber shape. The derivative exhibit ...

during the past two decades the use of lignocellouse fibers in reinforcing composites has attracted much research activities. in the present work, date palm fiber was used for production of composites compatible withliving environment. the fibers were pre-treated chemically to remove impurities. in order to verify and compare the effectiveness of the pretreatment methods, lignin, ash, moisture ...

A 14-year-old girl was first seen with an 8-month history of an asymptomatic “rash” on her chin and a “wart” on her right hand. At physical examination, she had several pink papules coalescing into annular and arcuate plaques on the central aspect of her chin (Figure 1). She was also noted to have a single flesh-colored verrucous papule on her right palm, which was treated with liquid nitrogen ...

A colored mixed graph has vertices linked by both colored arcs and colored edges. The chromatic number of such a graph G is defined as the smallest order of a colored mixed graph H such that there exists a (arc-color preserving) homomorphism from G to H . We study in this paper the colored mixed chromatic number of planar graphs, partial 2-trees and outerplanar graphs with given girth.

this paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. the properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...
