A nanostructure, being either an Inorganic Fullerene-like nanostructure or an Inorganic Nanotube, having the formula A1\u2212x-Bx-chalcogenide are described. In one embodiment, the wear insert can be turned end-for-end, and in another embodiment the wear insert can be flipped up-side down, to double the service life of the part. A software object parses the HTML, decomposes the page into constituent pieces and saves them to data structures as byte streams, which are cached, along with the software object, rendering multiple disk accesses unnecessary when the page is reconstituted. The chamfer is formed in such a way that the angle enclosed by the large surface side edge, is larger than an angle enclosed by a narrow side edge. A strap located adjacent the heel portion of the outer sole is provided for securing the cast shoe to a casted foot. In one embodiment, different feedback types are prioritized by groups, and each group has several feedback types sharing the same priority.
