This paper presents a simple linear algorithm for embedding (or drawing) a planar graph in the plane. The algorithm is based on the " vertex-addition " algorithm of Lempel, Even, and Cederbaum (" Theory of Graphs, " Intl. implementation of the testing algorithm using a PQ-tree. Compared with the known embedding algorithm of Hopcroft and Tarjan (J., this(More)
In an attempt to document the physiological value of seaweed on several biochemical criteria associated with atherosclerosis and coronary heart disease, it has been found that the green laver, Monostroma nitidum, is effective in lowering the plasma cholesterol (Abe & Kaneda 1971).
