1. Pectinase Activity of some Micromycetes Isolated from Agricultural Soils

N. Nayebyazdi

Volume 23, Issue 4 , Autumn 2012, Pages 305-311

Abstract
  Pectinases have multiple nature and various forms which are necessary for the hydrolysis of pectin in several conventional industrial and natural processes. In this investigation fourteen fungal strains which isolated from agricultural soils ,were screened for pectinase activity. Pectinase activity were ...  Read More

2. Synthesis and Characterization of V2O5/SiO2 Nanoparticles as Efficient Catalyst for Aromatization 1,4 Dihydropyridines

F. F. Farzaneh

Volume 23, Issue 4 , Autumn 2012, Pages 313-318

Abstract
  V2O5/SiO2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing MeOH, followed by calcination at 700 °C for 2 hours. The resultant nanoparticles was characterized by means of scanning electron microscopy (SEM), transmission electron ...  Read More

3. The Origin of Co-Magmatic Andesite Enclaves in the Rabor Miocene Pyroxene Andesites, SE Kerman, Iran: Insights from Textural and Mineralogical Composition

S. S. Dargahi

Volume 23, Issue 4 , Autumn 2012, Pages 319-335

Abstract
  The Miocene pyroxene andesite lava flows are exposed in southeastern edge of Urumieh Dokhtar Magmatic assemblage in Iran. The hypocrystalline andesite in parts contain conspicuous co-magmatic igneous enclaves which are dark grey and occur mostly as spherical and occasionally as ribbon shapes with some ...  Read More

4. Determination of Coal Seams Depth of Erosion with Respect to the Remnants of a Key Bed in Kerman Coal Field, Iran

A. A. Elahi

Volume 23, Issue 4 , Autumn 2012, Pages 337-346

Abstract
  As a tool for exploration of concealed coal seams by modern techniques, determination of the depth of erosion of coal seams with reference to the surface of angular unconformity underlying the remnants of a key bed is conducted for the first time in coal mines of Kerman region. The angular unconformity ...  Read More

5. New Randomized Response Procedures

Z. Z. Hussain

Volume 23, Issue 4 , Autumn 2012, Pages 347-357

Abstract
  This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively. In addition to unbiased estimation of population proportion and variance, an empirical ...  Read More

6. Nuclear-Charge Screening in Positronium Formation from Helium Atoms

E. Ghanbari-Adivi

Volume 23, Issue 4 , Autumn 2012, Pages 357-365

Abstract
  An analytical treatment of the electron screening effect within an active-electron model is given for positronium formation from helium atoms. A first-order distorted wave approximation with correct boundary conditions is applied to evaluate the transition amplitude. In the range of impact energy for ...  Read More
