1. Bioremediation Activity of Pb (II) Resistance Citrobacter sp. MKH2 Isolated from Heavy Metal Contaminated Sites in Iran

M. Mohseni

Volume 25, Issue 2 , Spring 2014, Pages 105-110

  Heavy metal pollution all around the world has become a major environmental concern and the bioremediation of polluted environments is an increasingly popular strategy due to both its efficiency and safety. In this study, a bacterial strain resistant to heavy metal was isolated from metal contaminated ...  Read More

2. Nickel-Chitosan Hybrid as a Precursor for Nickel Oxide Nanoporous Particles for Organic Dyes Photodegredation

F. Farzaneh

Volume 25, Issue 2 , Spring 2014, Pages 110-118

  Hydrothermal synthesis of nickel-chitosan hybrid  has  been accomplished using Ni(CH3COO)2,4H2O, chitosan and water as starting material, template and solvent respectively, followed by calcination at 800 and 900˚C to provide nanoporous NiO800  and NiO900. The solid products were characterized ...  Read More

3. Investigation of Organic Compounds as Photosensitizer for Dye Sensitized Solar Cells

A.D. Khalaji

Volume 25, Issue 2 , Spring 2014, Pages 119-124

  Two organic compounds (SC-23=(E)-2-Cyano-3-(2,3-dimethoxyphenyl) acrylic acid and SC-25=(E)-2-Cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. They shows ...  Read More

4. Chemoselective Synthesis of 1,1-diacetate Using Ni2+@ Hydroxyapatite-core@shell γ-Fe2O3 Nanoparticles as an Efficient and Reusable Lewis Acid Catalyst under Solvent Free Conditions

E. Rezaee Nezhad

Volume 25, Issue 2 , Spring 2014, Pages 125-132

  A simple and efficient method for the chemoselective 1,1-diacetate protection of aromatic aldehydes with acetic anhydride by using Ni2+ supported on hydroxyapatite-core-shell magnetic γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ni2+) under solvent free conditions. This method has several advantages, ...  Read More

5. Investigating the Effect of Specimen Diameter Size on Uniaxial Compressive Strength and Elastic Properties of Travertines

A. Jamshidi

Volume 25, Issue 2 , Spring 2014, Pages 133-141

  Uniaxial compressive strength (UCS) and elastic properties of rocks play a major and vital role for the design of any engineering structure. The specimen diameter size is one of the main factors that influencing on UCS, elasticity modulus and Poisson’s ratio (E and υ). Here, an attempt ...  Read More

6. Estimating of Crystallization Temperature of Mard-Abad (Karaj) Granitic Intrusion Using Mineralogy, Geochemistry and Morphology of Zircon Crystals

Z. Salehi

Volume 25, Issue 2 , Spring 2014, Pages 143-155

  Mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. Granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure ...  Read More

7. Localization of Eigenvalues in Small Specified Regions of Complex Plane by State Feedback Matrix

H. Ahsani Tehrani

Volume 25, Issue 2 , Spring 2014, Pages 157-164

  This paper is concerned with the problem of designing discrete-time control systems with closed-loop eigenvalues in a prescribed region of stability. First, we obtain a state feedback matrix which assigns all the eigenvalues to zero, and then by elementary similarity operations we find a state feedback ...  Read More

8. Nonharmonic Gabor Expansions

M. Amini

Volume 25, Issue 2 , Spring 2014, Pages 165-173

  We consider Gabor systems generated by a Gaussian function and prove certain classical results of Paley and Wiener on nonharmonic Fourier series of complex exponentials for the Gabor expansion‎. ‎In particular, we prove a version of Plancherel-Po ́lya theorem for entire functions with finite ...  Read More

9. Effective Mechanical Properties of Nanocomposites Reinforced With Carbon Nanotubes Bundle

M. Hashemi Gahruei

Volume 25, Issue 2 , Spring 2014, Pages 175-183

  Nanocomposites made of Carbon Nanotube (CNT) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness.  In this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are ...  Read More
