Modified Ammonia Removal Model Based on Equilibrium and Mass Transfer Principles

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

A Modified Model of Computational Mass Transfer for Distillation Column

The Computational Mass Transfer (CMT) model is composed of the basic differential mass transfer equation, closed by auxiliary equations and the appropriate accompanying CFD formulation. In the present modified CMT model, the closing auxiliary equations in the c2 1c model given by Liu (2003) are further simplified for reducing the computational complication. By this model, the turbulent mass tra...

Ethics-Based Parenting Model: Definition and training Principles based on Allameh Tabataba'i View Point

Aim: Ethics, that is, a permanent endurance of good moral qualities in the form of "Manesh" in human beings, which can not be achieved through mere moral education. Therefore, the purpose of this study is to obtain an ethics-based approach to parenting. Methods: For this purpose, in the first part of the study, we examined and explained the definition and principles of ethics- based training fr...

Removal of Cerium from Aqueous Solutions by Amino Phosphate Modified Nano TiO2: Kinetic, and Equilibrium Studies

Adsorption of Ce(III) from aqueous solution by amino phosphate modified nano TiO2 was investigated. Effects of pH of solution, adsorbent dose, contact time, initial metal concentration and temperature were examined. Experimental data were fitted well by the pseudo second order model. Adsorption was well described by Freundlich isotherm model with a maximum adsorption capacity of 25 mg g-1. Acco...
