1. Somaclonal Variation Among Somatic-Embryo Derived Plants of Olea europaea L “cv. Kroneiki”

M. Peyvandi

Volume 21, Issue 1 , Winter 2010

Abstract
  Frequency of somaclonal variation in embryogenic calli and plants of Olea europaea L cv.Kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic DNA (RAPD) analysis. Radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in OMc medium supplemented ...  Read More

2. A Thermodynamic Study of the Interaction between Urease and Copper Ions

A.A. Saboury; Elaheh Poorakbar-Esfahani; G. Rezaei-Behbahani

Volume 21, Issue 1 , Winter 2010

Abstract
  A thermodynamic study of copper ions by jack bean urease (JBU) was carried out at two temperatures of 27 and 37?C in Tris buffer (30 mM; pH=7.0) using an isothermal titration calorimetry. There is a set of twelve identical and non-interacting binding sites for copper ions. The intrinsic dissociation ...  Read More

3. Agrobacterium Mediated Transformation of Maize (Zea mays L.)

H. Rahnama

Volume 21, Issue 1 , Winter 2010

Abstract
  Agrobacterium tumefaciens mediated transformation may offer a better alternative than the biolistic gun for genetic transformation of maize plants. This gene delivery system results in a greater proportion of stable, low-copy number transgenic events than does the biolistic gun, and is highly efficient. ...  Read More

4. Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives

A.M.O. Abdul Raheem

Volume 21, Issue 1 , Winter 2010

Abstract
  The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states ...  Read More

5. Stratigraphy and Palaeontology of Trilobites in Kuhbanan Formation in the Akbar-Abad Section (North of Kerman)

H. Ameri

Volume 21, Issue 1 , Winter 2010

Abstract
  Cambrian sedimentary facies are exposed throughout north part of Kerman region. Trilobites’ faunas are the most common invertebrate fossils within the Cambrian strata. The section is made of 217 m of sandstone, shale, limestone and dolomite. In this study, 153 trilobite samples including seven species ...  Read More

6. Sexual Dimorphism in a New Species of Cassiduloid Echinoid, Pygaulus baghinensis, from the Aptian Strata of Baghin Area, West of Kerman, Iran

M.R. Vaziri

Volume 21, Issue 1 , Winter 2010

Abstract
  A new species of cassiduloid echinoids, Pygaulus baghinensis is reported for the first time from Aptian sediments of Baghin area, west of Kerman, Iran. The diagnostic features of the species are centrally positioned of the apical disc and approximately low profile of the test. Variation in gonopore size ...  Read More

7. Geohistory Analysis of the Tabas Block (Abdoughi-Parvadeh Basins) as Seen from the Late Triassic through Early Cretaceous Subsidence Curves

N. Naimi Ghassabiyan

Volume 21, Issue 1 , Winter 2010

Abstract
  The study area is situated in the Middle part of the Tabas Block. It contains outcrops of rocks that formed along longitudinal faults in Early Cimmerian orogenic phase. The basin subsided along these faults from the Late Triassic to Early Cretaceous, which include two sedimentary cycles. A sedimentary ...  Read More

8. Entropy Estimate for Maps on Forests

M. Sabbaghan

Volume 21, Issue 1 , Winter 2010

Abstract
  A 1993 result of J. Llibre, and M. Misiurewicz, (Theorem A [5]), states that if a continuous map f of a graph into itself has an s-horseshoe, then the topological entropy of f is greater than or equal to logs, that is h( f ) ? logs. Also a 1980 result of L.S. Block, J. Guckenheimer, M. Misiurewicz and ...  Read More

9. Optimization of Electrochemical Etching Parameters in FIM/STM Tungsten Nanotip Fabrication

V. Ahmadi

Volume 21, Issue 1 , Winter 2010

Abstract
  Field Ion Microscopy (FIM) and Scanning Tunneling Microscopy (STM) have found a wide application in nanotechnology. These microscopes use a metallic nanotip for image acquisition. Resolution of FIM and STM images depends largely on the radius of nanotip apex; the smaller the radius the higher the resolution. ...  Read More
