Predicting Solubility of Isotactic Poly (1-Butene) in Different Organic Solvents by Modified UNIQUAC
Volume 5, Issue 4 , October 2008, , Pages 39-48

Abstract
  The UNIQUAC activity coefficient model is extended to predict solid-liquid equilibrium of isotactic crystalline poly (1-butene), iPBu-1, in different organic solvents. The UNIQUAC activity coefficient model used in this work is based on the concept of group contribution and consists of combinatorial, ...  Read More

Investigation on the capability of Silkworm Pupa as a Natural Adsorbent for Removal of Dyes from Textile Effluent
Volume 1, Issue 2 , July 2004, , Pages 39-44

Abstract
  Recently, use of naturally-occurring low-cost and harmless material for removal of trace contaminants from colored wastewater has attracted extensive attention. In this study, silkworm pupa has been used as a basic dye adsorbent. Adsorption capacity and isotherms have been assessed. Results show that ...  Read More

Hydrodynamic Characteristics of Dense Conical Fluidized Bed: CFD Simulation and Experimental Verification

A. R. Bahramian

Volume 12, Issue 1 , January 2015, , Pages 42-59

Abstract
  > The hydrodynamic characteristics of dense conical fluidized bed were investigated experimentally and numerically. Experimental studies have been carried out in a bed containing TiO2 particles belonging to A/C boundary of Geldart's classification with a wide particle size distribution. Pressure measurements ...  Read More

Application of Bioaugmentation Technology to Improve the Activated Sludge Treatment Process in Removal of Aromatic Compounds
Volume 4, Issue 1 , January 2007, , Pages 43-53

Abstract
  This investigation was designed to evaluate the effects of bioaugmentation on maintaining the system stability under shock loading conditions, standardizing the effluent, and improving the sludge settlement. In this study, phenol was chosen as a model of mono-aromatic compounds which are found commonly ...  Read More

Numerical Study of Non-Newtonian Flow Through Rectangular Microchannels
Volume 6, Issue 4 , October 2009, , Pages 44-61

Abstract
  A numerical investigation was carried out to solve the flow dimensionless partial differential equations through rectangular microchannels. A purely viscous power law model was used to characterize the flow behavior of non-Newtonian fluids. The flow was assumed to be steady and laminar, and slip conditions ...  Read More

A hybrid neural–genetic algorithm for predicting pure and impure CO2 minimum miscibility pressure
Volume 3, Issue 4 , October 2006, , Pages 44-59

Abstract
  "> Accurate prediction of the minimum miscibility pressure (MMP) in a gas injection process is crucial to optimizing the management of gas injection projects. Because the experimental determination of MMP is very expensive and time-consuming, searching for a fast and robust mathematical determination ...  Read More

Decolorization of Distillery Wastewater by UV irradiated spores of Aspergillus fumigatus
Volume 2, Issue 2 , April 2005, , Pages 49-55

Abstract
  An efficient microbial technique for decolorizing distillery wastewater was achieved using irradiated spores of Aspergillus fumigatus. The fungus was isolated from soil samples taken from the local distillery processing unit. By using the irradiated spores, wastewater decolorization increased by 14.3% ...  Read More

Biological Conversion of Normal Chain Octadecane by Native Microbial Consortia

F. Ghavipanjeh*; M. Pazouki; Z. Ziaei Rad; A. Hosseinnia

Volume 12, Issue 2 , April 2015, , Pages 50-58

Abstract
  "> Long-chain alkanes are a major constituent of crude oils and their conversions into other compounds are of interest depending on the specific application. Here, five native microbial consortia obtained from petroleum polluted sites were examined for biological conversion of n-octadecane as a representative ...  Read More

Oil Sorption by Synthesized Exfoliated Graphite (EG)
Volume 5, Issue 1 , January 2008, , Pages 51-64

Abstract
  > In this paper a chemical method applied to synthesize exfoliated graphite (EG) is presented. In this method graphite intercalation compound (GIC) was firstly synthesized by chemical treatment of graphite flakes using a mixture of sulfuric and nitric acids followed by thermal shock of GIC at 1000°C ...  Read More

Mathematical modeling of a fixed bed chromatographic reactor for Fischer Tropsch synthesis
Volume 3, Issue 3 , July 2006, , Pages 51-64

Abstract
  In this research, Fischer Tropsch synthesis (FTS) has been modeled in the fixed bed chromatographic reactor for the first time by applying a rather complex dispersed plug flow model for fluid phase and linear driving force (LDF) model for adsorbent. Model equations are dynamic, multi-component, non-linear ...  Read More

The Modified Lennard-Jones and Devonshire Equation of State
Volume 5, Issue 3 , July 2008, , Pages 52-61

Abstract
  Lennard-Jones-Devonshire equation of state is an old but theoretical based EOS. The concept of the nearest neighboring molecules or coordination number is proposed to be a function of temperature and volume, whereas it is a constant in the original. The dilute gas and hard sphere limits of molecules ...  Read More
