This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic and anti-inflammatory actions of the oil.
A computer graph is a graph in which every two distinct vertices are joined by exactly one edge. The complete graph with n vertices is denoted by Kn. The following are the examples of complete graphs. The graph Kn is regular of degree n-1, and therefore has 1/2n(n-1) edges, by consequence 3 of the handshaking lemma.
Strong and Porous. For years, researchers have known that carbon, when arranged in a certain way, can be very strong. Case in point: graphene. Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions. But thereâs one drawback: while notable for its thinness and unique electrical properties, itâs very difficult to create useful, three-dimensional materials out of graphene.
