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 study, different indices of vegetation cover variations and different physicochemical properties of soil in three treatments of flood spreading, enclosure and grazing (control) were investigated and compared in in the region of Peshert in Mazandaran province. In order to measure different soil characteristics, 18 soil samples (six withdrawals at any treatment) from a depth of zero to 30...

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Introduction: The relationship between population health and income inequality has attracted much attention during the last two decades. But the question on which there is no consensus is that whether fluctuations in economic inequality would lead to changes in population health indices. Methods: In response to this question, life expectancy and mortality rate as health indicators and Gini coef...

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

Abstract In order to investigate the effects of nano silver and multi wall carbon nanotube levels on ‎some morphological and physiological traits of faba bean the present study was done. This ‎factorial experiment was conducted in a completely randomized design with three replications ‎and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed ‎the total number o...
