abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...

in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...

Money supply and velocity of money are important variables that affect inflation and product. Velocity of money is a key concept for economic policy, and it's getting more important since it is closely related to behavior of the demand for money. In this regard, Friedman believes that the volatility of money growth is the main factor of velocity of money, which in monetary economics literature ...

There are various ways for estimating velocity of money in economic literature and each has its own specific weaknesses and strengths. Particularly, since a great deal of financial innovations and changes have recently taken place affecting the velocity of money, many traditional methods can no langer calculate the equilibrium velocity of money, and they are no longer dependable from the econom...

for any educational program to be successful, many factors work hand in hand. based on pervious efl studies, teachers and learners are the keys to gain achievement. granted the fact that explicit and implicit practice plays a key role in education, knowledge of it can help teachers facilitate students’ vocabulary learning. this study investigated to determine the contribution of explicit and i...
