In this paper we investigate chromatic aspects for graphs with forbidden induced subgraphs with emphasis on the question of 3-colorability. In the main part all possible pairs (A,B) of forbidden induced subgraphs, s.t. every A- and B-free graph is 3-colorable, are determined. Moreover, this is embedded in a more general problem and the main result extends Vizing's classical edge coloring result. Terahertz imaging and conventional X-ray have been used to investigate a sealed Ancient Egyptian jar preserved at the Museum of Aquitaine (France). Terahertz radiation revealed an unknown content that could not have been visualized by X-ray. By comparison with a model object, we concluded that this content was composed of organic materials explaining their relative radiolucency. Spin models were introduced by Louis Vuitton Wallet Cheap Vaughan Jones to Louis Vuitton Bags On Sale Original construct invariants of knots and links (Pac. J. Math. 137 (1989), 311–336). This paper summarizes recent (1995–1997) results on spin models in connection with Bose–Mesner algebras. An apparatus for paper electrophoretic analysis is described in which a uniform pressure is applied to the paper in a very simple manner. The pressure is applied by hydraulic or pneumatic means and can be readily and accurately reproduced.
