Caterpillar (Gutman) Trees in Chemical Graph Theory

1990
Gutman trees (also known as caterpillar trees and benzenoid trees) are demonstrated to be elegant storage devices of information on graph-theoretical properties of many mathematical objects including benzenoid graphs, rook boards, king polyomino graphs, Clar graphs, and Young diagrams.

Chemical devitalization of stumps of hazel-trees and ash-trees

1990
Cet essai vise à tester 11 traitements destinés à dévitaliser des souches de noisetier et de frêne. Deux facteurs sont étudiés : le mode d'application (pulvérisation après la coupe, dépôt en même temps que la coupe, badigeonnage), la matière active (glyphosate ; triclopyr ; 2,4-D + 2,4-DP ; 2,4 - D + triclopyr ; sulfamate d'ammonium).
