M. Shams; S. Afsharzadeh; Gh. Balali

Volume 26, Issue 1 , Winter 2015, Pages 7-16

  Six species of Sargassum C. Agardh (Sargassaceae) with compressed primary branches, including: S. binderi Sonder, S. aquifolium (Turner)C. Agardh, S. oligocystum Montagne, S. swartzii (Turner)C. Agardh, S. crassifolium J. Agardh and S. cristaefolium C. A. Agardh, were identified in the Persian Gulf and ...  Read More

2. The Impact of Cadmium Loading In Fe/Alumina Catalysts and Synthesis Temperature on Carbon Nanotubes Growth by Chemical Vapor Deposition Method

M. Karimi; A. Badiei; P. Zarabadi-poor

Volume 26, Issue 1 , Winter 2015, Pages 17-24

  We evaluated the effect of Fe/Alumina Catalyst contained different Cadmium contents and two synthesis temperatures on producing carbon nanotubes by chemical vapor deposition of methane as a feedstock.  X-ray powder diffraction (XRD), N2 adsorption-desorption, scanning electron microscopy (SEM), ...  Read More

3. Regioselectivie Synthesis of New Spiro-Oxindolopyrrolidines via a Three-Component Asymmetric 1,3-Dipolar Cycloaddition Reaction of Azomethine Ylides aAnd Chiral Menthyl Cinnamate

M. J. Taghizadeh; F. Salahi; M. Hamzelooian; K. Jadidi

Volume 26, Issue 1 , Winter 2015, Pages 25-33

  An efficient, one-pot, four-component procedure for the synthesis of a small library of new chiral spiro- oxindolopyrrolidines with high regio-, diastereo- (>99:1 dr), and enantioselectivity (up to 80% ee) is described. In this process, the regio- and stereochemical 1,3-dipolar cycloaddition of azomethine ...  Read More

4. Insights into the Aftershocks and Inter-Seismicity for Some Large Persian Earthquakes

M. Nemati

Volume 26, Issue 1 , Winter 2015, Pages 35-48

  This paper focuses on aftershocks behavior and seismicity along some co-seismic faults for large earthquakes in Iran. The data of aftershocks and seismicity roughly extracted from both the Institute of Geophysics the University of Tehran (IGUT) and International Seismological Center (ISC) catalogs. Apply ...  Read More

5. Cyclic Orbit Codes with the Normalizer of a Singer Subgroup

F. Bardestani; A. Iranmanesh

Volume 26, Issue 1 , Winter 2015, Pages 49-55

  An algebraic construction for constant dimension subspace codes is called orbit code. It arises as the orbits under the action of a subgroup of the general linear group on subspaces in an ambient space. In particular orbit codes of a Singer subgroup of the general linear group has investigated recently. ...  Read More

6. Exp-Kumaraswamy Distributions: Some Properties and Applications

Z. Javanshiri; A. Habibi Rad; N.R. Arghami

Volume 26, Issue 1 , Winter 2015, Pages 57-69

  In this paper, we propose and study exp-kumaraswamy distribution. Some of its properties  are derived, including the density function, hazard rate function, quantile function, moments,  skewness  and kurtosis.   Adata set isused to illustrate an application of the proposed distribution. ...  Read More

7. Cesaro Supermodular Order and Archimedean Copulas

H.R. Nili Sani; M. Amini; M. Khanjari

Volume 26, Issue 1 , Winter 2015, Pages 71-76

  In this paper, we introduce a new kind of order, Cesaro supermodular order, which includes supermodular order and stochastic order. For this new order, we show that it almost fulfils all desirable properties of a multivariate positive dependence order that have been proposed by Joe (1997). Also, we obtain ...  Read More

8. Optimized Conditions for Catalytic Chemical Vapor Deposition of Vertically Aligned Carbon Nanotubes

M. Makenali; R. Ajeian; M. Tavakkoli; M. Nakhaee Badrabadi; S. Panahian Jand; M. Zare

Volume 26, Issue 1 , Winter 2015, Pages 77-85

  Here, we have synthesized vertically aligned carbon nanotubes (VA-CNTs), using chemical vapor deposition (CVD) method. Cobalt and ethanol are used as the catalyst and the carbon source, respectively. The effects of ethanol flow rate, thickness of Co catalyst film, and growth time on the properties of ...  Read More
