For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree Diameter at Breath Height in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran ...

the person, who, on his way, encounters a fruit-bearing tree belonging to others, can eat from its fruit as much as fulfilling his need, provided that his reaching to that tree has been accidental rather than on purpose; and that he should not take away any fruit with him and damage a tree or a fruit. in this respect, the owner’s consent is not considered a sine qua non. the reason for this rul...

landscape metrics quantifies structural features of the landscape. one of the advantages of these metrics is a possibility to use them in fast cumulative assessment of the development activities in the environment. in this paper, the cumulative effects of road network expansion on the tree cover of gorgan, kordkuy, aliabad townships in golestan province were investigated. to prepare the require...

). In this note we provide another bijection, which is simpler. Furthermore, it preserves more of the structure of the tree. The basic idea is that, when • ◦ is forbidden, any sequence of nodes connected by right edges must have labels white . . . white, followed by black . . . black. We translate the restricted 2-binary tree recursively into a ternary tree from the root to the leaves, by leavi...

The derivation trees of a tree adjoining grammar provide a first insight into the sentence semantics, and are thus prime targets for generation systems. We define a formalism, feature-based regular tree grammars, and a translation from feature based tree adjoining grammars into this new formalism. The translation preserves the derivation structures of the original grammar, and accounts for feat...
