Jasper

Silicon makes up 25.7% of the earth s crust, by weight, and is the second most abundant element, being exceeded only by oxygen. Silicon is not found free in nature, but occurs chiefly as the oxide and as silicates. Sand, quartz, rock crystal, amethyst, agate, flint, jasper, and opal are some of the forms in which the oxide appears. Granite, hornblende, asbestos, feldspar, clay, mica, etc. are but a few of the numerous silicate minerals. [Pg.33]

A compilation of some 2200 liquid compounds has been prepared by J. J. Jasper, J. Phys. Chem. Reference Data 1 841 (1972). [Pg.449]

The molecules in a gas-hquid interface are in tension and tend to contract to a minimum surface area. This tension may be quantified by the surface tension, which is defined as the force in the plane of the surface per unit length. Jasper" has made a critical evaluation of experimental surface tension data for approximately 2200 pure chem-ic s. He correlates surface tension C (mN/m = dyn/cm) with temperature T (°C) over a specified temperature range as... [Pg.416]

C-type pigmentation were observed in the northern part of the range of L. californica. Populations exhibiting (predominantly) A-type flavonoid chemistry occurred in Arizona and central and southern California. The study area at Jasper Ridge belongs to the latter group. [Pg.91]
