with recently widespread use of mobile phones and sms communication in iran and reformulation of conventional communication practices, short message advertisements have recently started to gain prominence in the world of advertisement as a quick, less costly, available and reliable means of introducing the products and services offered by the companies and institutions. with this in mind, the p...

in this work, we report results of calculations based on the density functional theory of different species metal-ozone, containing mercury, silver and gold. the chosen species range from small molecules and large transition-metal containing ozone with mercury, silver and gold complexes. a comparative analysis of the description of the metal-oxygen bond obtained by different methodologies is pr...

the stability problem of the functional equation was conjectured by ulam and was solved by hyers in the case of additive mapping. baker et al. investigated the superstability of the functional equation from a vector space to real numbers.in this paper, we exhibit the superstability of $m$-additive maps on complete non--archimedean spaces via a fixed point method raised by diaz and margolis.

objective(s): first principles calculations were performed to study four multiple sclerosis drugs namely, ampyra, fingolimod, mitoxantrone and eliprodil in gas and liquid phases using density functional theory (dft). computational chemistry simulations were carried out to compare calculated quantum chemical parameters for ampyra, fingolimod, mitoxantrone and eliprodil. materials and methods: al...

objective: to determine the effects of recombinant human erythropoietin (rhepo) on functional outcome and disability of patients with traumatic cervical spinal cord injury (sci).  methods: this was a randomized, double blind, placebo controlled clinical trial being performed in nemazee and shahid rajaei hospitals of shiraz during a 3-year period from 2011 to 2014. a total number of 20 patients ...

one main group of organic chemistry is related to the aromatic compounds. in the present work, we replaced the ch group of benzene by silicon and nitrogen analogues. then, density functional theory (dft) calculations were carried out for six-membered heterocyclic si-n aromatic rings. full geometry optimizations were performed in gas-phase, and at b3lyp level using 6-311++g(d,p) and cbsb7 basis ...

density functional theory (dft) calculations were performed to investigate the properties of planar, tubular and conical forms of silicon nanostructures. the evaluated parameters including averaged bond lengths, binding energies, gap energies and dipole moments were then evaluated for the optimized models of study. the results indicated that the bond lengths between silicon atoms are different ...
