Synthesis and structural studies of some metal complexes of tetraaza macrocyclic ligands
Published 1993“…A series of dibenzo macrocyclic tetraamine ligands with 14-, 15-, 16-, 17- and 19-membered inner great lings (L14 to L15) has been synthesized to investigate the effect of ring size variation on their complexation behaviour with the metal-ions, Ni(Il), Zn(ll) and Cd(II).…”

Two Potts Models on Cayley Tree of Arbitrary Order
Published 2012“…On a Cayley tree of arbitrary order k we consider two different Potts models with competing nearest-neighbour interactions J1 and next-nearest-neighbour interactions Jp and Jo, where coupling Jp corresponds to interaction of spins belonging to the same branch of the tree (prolonged) and coupling Jo corresponds to interaction of spins belonging to the same shell of the tree (one-level) and find for each model in addition to the expected paramagnetic, ferromagnetic and antiferromagnetic phases, an intermediate range of coupling values where the local magnetization has chaotic oscillatory glass-like behaviour. …”

Attractors on Ising Model with Restricted Interactions on Cayley Tree of Order 2
Published 2013“…In this paper we reinvestigate the phase diagram of this model using an iterative scheme, that is developed for a renormalized effective nearest-neighbour coupling Kr and effective field per site Xr for spins on the n-th level of a Cayley tree with competing one-level J0 and prolonged Jp next-nearest-neighbour interactions between Ising spins on the tree. …”

Editorial
Published 2010“…It would be instructive, therefore, to reflect on Martin Lings' explanation of the concepts of "development" (tatawwur), "progress" (taqaddum), "renewal" (tajdid) and "renaissance" (nahdah).....…”
