the effect of alkyl substituents on the c-phenyl and/or the n-phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. the predominant configuration in chcl3 is determined by steric and electronic effects. substituents on the c-phenyl ring favor the cis configuration, while substituents in the n-phenyl ring favor a trans configuration. t...

trust is one of the most important factors for the development of electronic banking. the purpose of this study is to determine effective factors on trust in e-banking in the form of a conceptual model. due to the rapid growth of electronic banking in the country, identify factors affecting trust in e-banking is very important. population of this study is customers of bank melli in urmia. we us...

density functional theory (dft) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1h)–one (mpo), as a representative of pyridinone derivatives, at the fullerene (c60) surfaces. optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (cq) have been evaluated to investigate the str...

OBJECTIVE With the rapid increase in use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigarettes), users and non-users are exposed to the aerosol and product constituents. This is a review of published data on the human health effects of exposure to e-cigarettes and their components. METHODS Literature searches were conducted through September 2013 using mu...

background: using thinking-based scientific methods such as paper-based and electronic nursing processes in nursing education can lead to education of skilled and efficient experts that can affect students’ satisfaction in addition to their quality of care. the present study aimed to compare the effects of recording and implementing the nursing process based on two methods (paper-based and elec...

objective: trauma is a major health problem worldwide regardless of regional socioeconomic and healthcare status. as a leading cause of death, trauma results in severe socioeconomic damages, which could be highly prevented by optimal care. as nurses are the major professional groups involved in patient care, improvement of their knowledge and practical skill leads to more qualified healthcare s...

The electronic and structural properties of single wall carbon nanotubes (SWCNTs) interacted with 4-amino phenyl-azobenzene were theoretically investigated by using the hybrid DFT (hybrid-density functional theory) calculations. The amount of thermodynamic parameters of this reaction in the gas and aqueous phase suggesting thermodynamic favourability for adsorption of 4-amino phenyl-azobenzene ...
