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

  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

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 , July 2004, Pages 11-18

  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

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

  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

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

   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

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

  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

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

  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
