1. Photosynthetic Characteristics and Antioxidative Responses in Three Species of Crassulaceae Following Drought Stress

R. Hajoboland

Volume 21, Issue 3 , Summer 2010

Abstract
  Photosynthetic characteristics and induction of crassulacean acid metabolism (CAM) by drought stress were investigated in Sedum album, Sedum stoloniferum and Rosularia elymaitica from Crassulaceae. Titratable acidity, malate content, phosphoenolpyruvate carboxylase (PEPC) activity and gas exchange parameters ...  Read More

2. Carbon and Oxygen Isotopic Systematics in Calcite and Dolomite from the Sangan Iron Skarn Deposit, Northeastern Iran

M Boomeri

Volume 21, Issue 3 , Summer 2010

Abstract
  A total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the Sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. The higher values of ?18O are from metamorphic calcite and dolomite and lower ones are from granitic rocks. Although the ?18O ...  Read More

3. Nonlinear Responses and Optical Limiting Behavior of Ag Nanoparticle Suspension

N Mansour

Volume 21, Issue 3 , Summer 2010

Abstract
  In this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (AgNPs) in distilled water are investigated. The nonlinear absorption coefficient of the colloid is measured by the Z-scan technique. The optical limiting behavior of the AgNP suspension is investigated ...  Read More

4. Plasmonic Thermal Conductance of Stack of Metallic Nanorings

M Jafari

Volume 21, Issue 3 , Summer 2010

Abstract
  In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker ...  Read More

5. A New Parallel Matrix Multiplication Method Adapted on Fibonacci Hypercube Structure

L Jokar

Volume 21, Issue 3 , Summer 2010

Abstract
  The objective of this study was to develop a new optimal parallel algorithm for matrix multiplication which could run on a Fibonacci Hypercube structure. Most of the popular algorithms for parallel matrix multiplication can not run on Fibonacci Hypercube structure, therefore giving a method that can ...  Read More

6. Fractional Probability Measure and Its Properties

H Mostafaee

Volume 21, Issue 3 , Summer 2010, Pages 259-264

Abstract
  Based on recent studies by Guy Jumarie [1] which defines probability density of fractional order and fractional moments by using fractional calculus (fractional derivatives and fractional integration), this study expands the concept of probability density of fractional order by defining the fractional ...  Read More

7. Camparison of Numerically Stability of Two Algorithms for the Calculation of Variance

D Rostami

Volume 21, Issue 3 , Summer 2010

Abstract
  In descriptive statistics, there are two computational algorithms for determining the variance S2, of a set of observations : Algorithm 1: S2= - , Algorithm 2: S2= , where . It is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. I this ...  Read More

8. Geochemistry of Major, Trace, and Rare Earth Elements in Biglar Permo-Triassic Bauxite Deposit, Northwest of Abgarm, Ghazvin Province, Iran

A.A Calagari

Volume 21, Issue 3 , Summer 2010

Abstract
  Biglar Permo-Triassic bauxite deposit is located in ~15 km northwest of Abgarm, southwest of Ghazvin province, west of central Iran. It consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of Ruteh (Permian) and Elika (Triassic) carbonate formations. Petrographically, the ...  Read More

9. Lithostratigraphy and Microbiostratigraphy of the Ruteh Formation in Northwest of Khur, Central Alborz, Iran

M Mahdavi

Volume 21, Issue 3 , Summer 2010

Abstract
  A sequence of Permian rocks crops out in Northwest of Khur in Central Alborz, North of Iran. This sequence consists of the Dorud (Asselian-Sakmarian), Ruteh (Artinskian-Murgabian) and Nesen (Early Djulfian) formations. The Ruteh and Nesen formations in Alborz Range were deposited in a shallow marine ...  Read More
