To determine the potential habitat of two rangeland species of Salsola rigidaand Agropyron trichophorum in Qasr-e-Shirin, Iran, Geographic Information Systems(GIS) and Remote Sensing (RS) techniques were used. At first, several maps (vegetationcover and land uses maps and thematic maps of various organizations) were collected orprepared. For digitizing geology, vegetation and conventional state...

436 BRIEF NOTES

Thus if x has infinite order then the elements in the set {x|k ∈ Z} are all distinct while if x has order o(x) ≥ 1 then x = e exactly when k is a multiple of o(x). Thus x = x whenever m ≡ n modulo o(x). By the First Isomorphism Theorem, < x >∼= Z/o(x)Z. Hence when x has finite order, | < x > | = o(x) and so in the case of a finite group, this order must divide the order of the group G by Lagran...
