1. Treatment of Tehran Refinery Effluents in UASB Reactors
Volume 1, Issue 2 , Summer 2004, Pages 3-10

Abstract
  This paper presents the results of an investigation into the treatment of Tehran Refinery effluents in UASB reactors. Four pilot-scale UASB reactors were built with similar dimensions, each with a volume of 45.78 1, and operated in parallel at 37 °C. The sludge seed was prepared from the waste activated ...  Read More

2. Characterization of Copper-Manganese Oxide Catalysts and Their Precursors: Effect of Precipitate Aging upon the Structure and Morphology of Precursors and Catalysts
Volume 1, Issue 2 , Summer 2004, Pages 11-18

Abstract
  Copper-manganese oxide catalysts are prepared with an atomic ratio of Cu/Mn=2/1 using a coprecipitation procedure under air atmosphere. The time of aging, i.e., the time that precipitate remains in contact with the precipitating medium, has been varied from 0 (for unaged precursor) to 300 minutes and ...  Read More

3. Theoretical and Experimental Study of Falling- Cylinder Rheometer
Volume 1, Issue 2 , Summer 2004, Pages 19-27

Abstract
  The present study attempted deriving and solving the falling- cylinder governing equations for power law model non-Newtonian fluids. Based on this theoretical study, a novel falling- cylinder rheometer (FCR) was designed and constructed to measure the Theological properties of non-Newtonian fluids. Different ...  Read More

4. Immobilization of Rhizomucor miehei Lipase on High Density Polyethylene
Volume 1, Issue 2 , Summer 2004, Pages 29-37

Abstract
   Immobilization of Lipase produced from Rhizomucor miehei on HDPE fine powder was investigated. As compared to an aqueous system, immobilization in a non-aquous organic medium such as n-hexane was not successful and caused enzyme denaturation. Prewetting the support with ethanol increased the immobilized ...  Read More

5. Investigation on the capability of Silkworm Pupa as a Natural Adsorbent for Removal of Dyes from Textile Effluent
Volume 1, Issue 2 , Summer 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

6. Newtonian and Non-Newtonian Blood Flow Simulation after Arterial Stenosis- Steady State and Pulsatile Approaches
Volume 1, Issue 2 , Summer 2004, Pages 45-53

Abstract
  Arterial stenosis, for example Atherosclerosis, is one of the most serious forms of arterial disease in the formation of which hemodynamic factors play a significant role. In the present study, a 3-D rigid carotid artery with axisymmetric stenosis with 75% reduction in cross-sectional area is considered. ...  Read More

7. SHAHAB-A PC-Based Software for Simulation of Steam Cracking Furnaces (Ethane and Naphtha)
Volume 1, Issue 2 , Summer 2004, Pages 55-70

Abstract
  SHAHAB is a PC- based simulator developed by Olefin Research Group (ORG), with the simultaneous simulation of the reactor, the firebox, the convection section and the transfer line exchanger in steam Cracking units. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical ...  Read More
