safflower is one of the oldest cultivated plants and oilseed as a native iran could have in the development of oilseeds cultivation. to evaluate the morphological characteristics of safflower (carthamus tinctorius l) an experiment was conducted as a completely randomized design. the figures include 1- pi 23755 2-pi 239041 3- pi 250202 4- pi 250532 5- pi 25268 6- pi 253515 7- pi 253541 8- pi 253...

topological indices are numerical parameters of a graph which characterize its topology. inthis paper the pi, szeged and zagreb group indices of the tetrameric 1,3–adamantane arecomputed.
