The potential of buckling in compressive members has been considered as a disadvantage when using steel members in the construction industry. In spite of the progress made in this regard, buckling is still considered as a challenge in the analysis and design of compressive steel structural members. Such a challenging phenomenon can be controlled by strengthening of compressive members. Stiffene...

In this paper, we demonstrate that the optical microangiography (OAMG) is capable of depth-resolved imaging of directional blood perfusion within both retinal and choroid in the posterior segment of human eye. The study uses an OMAG system operating at 840 nm with an imaging speed at 27,000 A-scans per second. Sequentially registered multiple OMAG projection maps of small areas ( approximately ...

Localization of substance P (SP)-like immunoreactivity in the anterior eye segment of the squirrel was examined immunohistochemically. The present study demonstrates a dense network of SP-positive fibers in the ciliary body, particularly in the muscle layers, and several SP-positive fibers in the iris, in addition to scattered SP-positive fibers in the cornea. These facts strongly suggest that ...
