Diamond cubic strong isotropic property. Namely, for any two vertices "x" and "y" of the crystal net, and for any ordering of the edges adjacent to "x" and any ordering of the edges adjacent to "y", there is a net-preserving congruence taking "x" to "y" and each "x"-edge to the similarly ordered "y"-edge. Another (hypothetical) crystal with this property is the Laves graph (also called the K crystal, (10,3)-a, or the diamond twin). The compressive strength and hardness of diamond and various other materials, such as boron nitride, is attributed to the diamond cubic structure. Similarly truss systems that follow the diamond
Ambo Mineral Water Ambo Mineral Water began to be packed in plastic bottles relatively recently, and prior to this was packed exclusively in glass bottles. New products introduced circa November 2014 were Ambo flavored water, which was formulated in several flavors, and Ambo Lite, a product with a lower mineral and carbonation content. Ambo Mineral Water Ambo Mineral Water is a brand of naturally-carbonated bottled mineral water, sourced from the springs in Ambo Senkele, near the town of Ambo in central Ethiopia. It is a popular drink in Ethiopia, and has been described as the "oldest modern mineral water" and Ethiopia's "oldest mineral
