background & aim: lemon verbena (lippia citriodora h.b.k.) is a richly scented herb and has a long history as a sacred and medicinal plant. select an appropriate medium in tissue culture is a necessity for success experimental: to evaluate the effect of 10 medium of previous researches for lippia micropropagation (1- ms medium supplemented with bap (3 mgl-1) + iba (0.1 mgl-1) + activated ch...

lisiantus is introduced among the 10 top cutting flowers in the world. micropropagation can be used in this plant because of some problems in traditional propagation. in this research, the effects of the growth regulators on the in vitro shoot regeneration and rooting of the shoots obtained from nodal explants were investigated. the effects of the different concentrations of bap and kin on shoo...

• For each player i, a partition Ii of {h ∈ H : P (h) = i} (i.e., each history occurs in exactly one of the sets in Ii), such that if h, h ∈ Ii, then A(h) = A(h). The collection Ii is the information partition of player i, and a member Ii ∈ Ii is an information set of player i. For any information set I , let P (I) and A(I) denote the player and action set corresponding to the information set. ...

Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

ab initio calculations at hf/6-31g* level of theory for geometry optimization and mp2/6-31g*//hf/6-31g* for a single point total energy calculation are reported for the importantenergy-minimum conformations and transition-state geometries of 1, 3-diazacyclohepta-1, 2-diene (2) and 1, 3-diazacycloocta-1, 2-diene (3). the c2 symmetric twist-chair (2-tc)conformation of 2 is calculated to be 7.4 kj...

In this paper‎, ‎we give the notions of crossed polymodule and cat$^1$-polygroup‎ ‎as a generalization of Loday's definition‎. ‎Then‎, ‎we define the pullback cat$^1$-polygroup and we obtain some results in this respect‎. ‎Specially‎, ‎we prove that by a pullback cat$^1$-polygroup we can obtain a cat$^1$-group‎.
