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...

in this paper some upper and lower bounds for the greatest eigenvalues of the pi and vertex pimatrices of a graph g are obtained. those graphs for which these bounds are best possible arecharacterized.

Abstract The role of the triangle mechanism in decay processes and K^0a_0\to K^0 \pi^0\eta is probed. In these processes, singularity appears from B^0 into J/\psi\phi , then, ϕ decays K^0\bar{K^0} merged f_0 or a_0 which finally \pi^+\pi^- respectively. We find that this leads to a around M_{\rm inv}(K^0f_0(a_0))\approx1520\ {\rm MeV} gives s...

The aim of present investigation was to study the virulence of coccidiosis in Kadaknath birds, experimentally infected with E. tenella by OPG count, oocyst index and caecal lesions scoring. Sixty one-day old unsexed Kadaknath birds were randomly divided into a control, T1 and T2 groups comprising twenty chicks under each group. At d 21 of age, birds of T1 and T2 groups were individually inocula...

in this paper, at first we mention to some results related to pi and vertex co-pi indices and then we introduce the edge versions of co-pi indices. then, we obtain some properties about these new indices.

Phosphatidylinositol (PI) is a component of membrane phospholipids, and it functions both as a signaling molecule and as a compartment-specific localization signal in the form of polyphosphoinositides. Arachidonic acid (AA) is the predominant fatty acid in the sn-2 position of PI in mammals. LysoPI acyltransferase (LPIAT) is thought to catalyze formation of AA-containing PI; however, the gene t...

Molecules of 5-methyl-2-phenyl-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C21H17N3, (I), are linked into chains by a combination of a C-H...pi(arene) hydrogen bond and a pi-pi stacking interaction; in the closely related 5-methyl-2-(4-methylphenyl)-6,7-dihydrobenzo[h]pyrazolo[1,5-a]quinazoline, C22H19N3, (II), there are no hydrogen bonds and the molecules are linked into centrosymmetric dim...

in this paper, we present some inequalities for the co-pi index involving the some topological indices, the number of vertices and edges, and the maximum degree. after that, we give a result for trees. in addition, we give some inequalities for the largest eigenvalue of the co-pi matrix of g.
