1. New Species of Five-Toed Jerboa (Rodentia: Dipodidae, Allactaginae) from North-East Iran
Volume 19, Issue 2 , Summer 2008

Abstract
  The five-toed jerboas of genus Allactaga Cuvier, 1837 have been distributed in arid and semi-desert regions throughout northern Africa, Iranian Plateau and Central Asia to Mongolia. This genus has 12 species of which five have been so far reported from Iran including, Small Five-toed Jerboa (A. elater), ...  Read More

2. Application of Polypyrrole Coated Stainless-Steel Wire to the Headspace Solid-Phase Microextraction of Aliphatic Amines
Volume 19, Issue 2 , Summer 2008

Abstract
  The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and ...  Read More

3. Preparation of Carbon Nanotubes by CVD Process over Nanoparticles of Ni-Ce-Zr Mixed Oxides
Volume 19, Issue 2 , Summer 2008

Abstract
  Carbon nanotubes (CNTs) were prepared by the catalytic chemical vapor deposition of C2H2 at 550°C in 120 minutes using nanoparticles of Ni-Ce-Zr mixed oxides. The CNTs were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy ...  Read More

4. Auriferous Sulfides from the Chah-Bagh Gold Occurrence, Muteh Mining District
Volume 19, Issue 2 , Summer 2008

Abstract
  The Chah-Bagh gold occurrence is located in Muteh mining district, in the central part of the Sanandaj-Sirjan zone. Gold mineralization occurs in ductile to ductile-brittle shear zones and is comparable with orogenic gold deposits. Silicification and sulfidization are the most important hydrothermal ...  Read More

5. Solid Solution in the As2S3-Sb2S3 Series at
Volume 19, Issue 2 , Summer 2008

Abstract
  Orpiment, getchellite and stibnite from Zarshuran deposit, NW Iran, exhibit extensive As-Sb substitution. There are four known minerals along As2S3-Sb2S3 join, i.e. orpiment (As2S3), Wakabayashilite [(As,Sb)20S30], getchellite (AsSbS3) and stibnite (Sb2S3). Extensive mineralogical studies by scanning ...  Read More

6. On Ideals Which Have the Weakly Insertion of Factors Property
Volume 19, Issue 2 , Summer 2008

Abstract
  A one-sided ideal of a ring has the insertion of factors property (or simply, IFP) if implies r for . We say a one-sided ideal of has the weakly IFP if for each , implies , for some non-negative integer . We give some examples of ideals which have the weakly IFP but have not the IFP. ...  Read More

7. Bracket Products on Locally Compact Abelian Groups
Volume 19, Issue 2 , Summer 2008

Abstract
  We define a new function-valued inner product on L2(G), called ?-bracket product, where G is a locally compact abelian group and ? is a topological isomorphism on G. We investigate the notion of ?-orthogonality, Bessel's Inequality and ?-orthonormal bases with respect to this inner product on L2(G).  Read More

8. ?-Independent and Dissociate Sets on Compact Commutative Strong Hypergroups
Volume 19, Issue 2 , Summer 2008

Abstract
  In this paper we define ?-independent (a weak-version of independence), Kronecker and dissociate sets on hypergroups and study their properties and relationships among them and some other thin sets such as independent and Sidon sets. These sets have the lacunarity or thinness property and are very useful ...  Read More

9. Weighted Convolution Measure Algebras Characterized by Convolution Algebras
Volume 19, Issue 2 , Summer 2008

Abstract
  The weighted semigroup algebra Mb (S, w) is studied via its identification with Mb (S) together with a weighted algebra product *w so that (Mb (S, w), *) is isometrically isomorphic to (Mb (S), *w). This identification enables us to study the relation between regularity and amenability of Mb (S, w) and ...  Read More

10. Combination of Colour Favoured and Colour
Volume 19, Issue 2 , Summer 2008

Abstract
  In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated ...  Read More
