for preventing groundwater and soil from heavy metal contamination and/or to decrease contamination, and to clean up the former disposal sites from these metals, one must be beforehand able to predict the movement of these pollutants in soils. in this research in order to describe cadmium [cd (ii)] transport in soils, we incorporated an equilibrium-kinetic two-site model into the convection-dis...
A complete set of scaling criteria for gas hydrate reservoir of five-spot well system case is derived from the 3D governing equations, involving the mass balance equation, the energy balance equation, the kinetic model, the endothermic model and the phase equilibrium model. In the scaling criteria, the key parameters of the experiment are the water/gas production rates, the water injection rate...
in this paper, changes of casson non-newtonian fluid velocity profile, for different distribution of porosity, have been investigated. for distribution of porosity, fixed, radial and exponential variations has been considered. for all three states, brinkman model has been used as momentum equation. since the casson fluid is a good model for blood, this analysis can be used in studying about cho...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
Background and Objectives: Eating disorders include a range of illnesses associated with weight gain or weight loss. Studies show that this disorder begins in the middle to late adolescence (14-18 years old) and is also more prevalent in female sex. The purpose of this study was designing and testing a model of antecedents of eating disorders symptoms in undergraduate female students of Isfahan...
In this article, a compressible two-phase reduced five-equation flow model is numerically investigated. The model is non-conservative and the governing equations consist of two equations describing the conservation of mass, one for overall momentum and one for total energy. The fifth equation is the energy equation for one of the two phases and it includes source term on the right-hand side whi...
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...
Abstract. The Fokker-Planck equation (FPE) approximation is applied to a subspace of the state space of the chemical master equation (CME). The CME-FPE-hybrid method exploits the lower cost of the FPE approximation compared to the full CME. A fourth order finite difference approximation of the FPE part of the hybrid is described and demonstrated on a biologically relevant model in five dimensions.
Personality traits have rarely been used to discussed the phenomenon under information systems context, especially not in the emerging topic of IS continued usage. IS continuance gained prominence because it is seem as the key indicator to the successfulness of information systems. This study explores and proposed a model to connect personality traits to IS continued usage through the introduct...
