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 ...
1. introduction one of the basic needs in the field of rural development is providing social health for villagers to to create appropriate basis to use social, economic and environmental possibilities of the village. so, rural development does not just include economic and agricultural aspects, but includes other aspects of life such as environmental, social, wellbeing and health aspects. hence...
In this study, the general partial differential equation of unsteady groundwater flow through non-homogeneous and anisotropic aquifer was solved by the fully implicit finite difference method with control volume approach. The calibration of permeability and storage coefficients as model parameters was performed by a transformation technique and application of Powell's non-linear optimization me...
Aim: Students are one of the most talented and promising segments of society and future builders of their country, and their level of health and psychological well-being will have a significant impact on learning and increasing their scientific awareness and academic success. Therefore, the purpose of this study was to investigate a structural model of psychological well-being based on negative...
