Chemical Interactions between Cloud Droplets and Trees

1988
The chemical composition of both liquid droplet and leaf surface determines the behaviour of a cloud droplet on interception by vegetation. In some circumstances, particularly in wind-driven cloud, droplets may not adhere to foliage. Once on the leaf surface, the contact angle between the droplet and surface will determine the amount of water held by ...

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.

On Randić indices of chemical trees and chemical unicyclic graphs [PDF]

MATCH : communications in mathematical and in computer chemistry, 2009
The fourth maximum Randić indices for the n-vertex chemical trees for n /10 and n-vertex chemical unicyclic graphs for n / 7 are determined, respectively.

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).
