1. Biodecaffeination by Pseudomonas pseudoalcaligenes TPS8, an Isolated Strain from Tea Plantation Soil

morahem Ashengroph; Sajad Ababaf

Volume 24, Issue 4 , Autumn 2013, Pages 305-312

  Development of an environmental friendly and cost-effective process for microbial degradation of caffeine to non-toxic compounds are promising to solve the problems of physiochemical extraction of caffeine in the treatment the caffeine containing agro-industrial effluents. Thirteen bacterial strains, ...  Read More

2. The Different Antibacterial Impact of Silver Nanoparticles Against Legionella pneumophila Compared to Other Microorganisms

M.R. Pourmand; K. Shahidi; P. Nazari; Seyed M. Moosavian; N. Samadi; Gh. Pourmand; A. R. Shahverdi

Volume 24, Issue 4 , Autumn 2013, Pages 313-319

  Legionella pneumophila is the pathogen responsible for severe pneumonia known as Legionnaires’ disease. Legionella can live under varied stress conditions, especially in cold environments, and is common in many artificial environments. In this study, the antimicrobial activity of biogenic silver ...  Read More

3. Karyotype of Hairless Guinea pig

fatemeh - Todehdehghani; Mohammah hassan motedayen; Shohreh Teimorzadeh

Volume 24, Issue 4 , Autumn 2013, Pages 321-324

  Chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. Chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and G banding ...  Read More

4. Formation and stability of organic layers around inorganic particles in aqueous media: an introduction to origin of life

Farnaz Jahanbin; Mohammad Khodadadi-Moghaddam; Shahab Bohlooli

Volume 24, Issue 4 , Autumn 2013, Pages 325-333

  Formation of non bonded organic layer around inorganic particles like iron sulfide and zeolites, was hypothesized as starting point for one of the possible mechanisms of the origin of life on earth. In this study, the general circumstances needed for creation of such organic layer was investigated. An ...  Read More

5. Composition of volatile compounds of extract of Ammi majus from Iran by GC-MS

Sh. Nayebi; T. Kakeshpour; A. Hasanvand; M. Nadri; S. Rashidi Monfared

Volume 24, Issue 4 , Autumn 2013, Pages 335-338

  Abderaz The composition of the essential oil obtained from the seeds of Ammi majus L. which collected from province of Khozestan in the southwest area of Iran.The oils was analyzed by gas chromatography mass spectrometry (GC-MS). Twenty - eight components have been identified in the extract of A. ...  Read More

6. Heavy metal concentration of soils affected by Zn-smelter activities in the Qeshm Island, Iran

F. Moore; S. Kargar; F. Rastmanesh

Volume 24, Issue 4 , Autumn 2013, Pages 339-346

  In this study, concentrations of heavy metals in soils around a Zn-smelter in Qeshm island, Iran, are investigated. Calculated geoaccumulation index (Igeo), contamination factor (Cf), and contamination degree (Cdeg) values indicate surface soil contamination by toxic metals (As, Cd, Pb, and Zn). The ...  Read More

7. Modified F-Expansion Method Applied to Coupled System of Equation

A. Aasaraai; M.B. Mehrlatifan; S. Khaleghizadeh

Volume 24, Issue 4 , Autumn 2013, Pages 347-354

  A modified F-expansion method to find the exact traveling wave solutions of  two-component nonlinear partial differential equations (NLPDEs) is discussed. We use this method to construct many new solutions to the nonlinear Whitham-Broer-Kaup system (1+1)-dimensional. The solutions obtained include ...  Read More

8. RAWSN: A Routing Algorithm Based on Auxiliary Nodes to Reduce Energy Consumption in Wireless Sensor Networks

A.A. Baradaran

Volume 24, Issue 4 , Autumn 2013, Pages 355-359

  In this paper, an algorithm , based on genetics and auxiliary nodes, to reduce energy consumption in wireless sensor networks has been presented. In this research, by considering some parameters as energy and distance, a target function has been created, which is more optimum comparing to other methods. ...  Read More

9. Some properties of n-capable and n-perfect groups

M. R. Rismanchian

Volume 24, Issue 4 , Autumn 2013, Pages 361-364

  In this article we introduce the notion of n-capable groups. It is shown that every group G admits a uniquely determined subgroup (〖Z^n)〗^* (G) which is a characteristic subgroup and lies in the n-centre subgroup of the group G. This is the smallest subgroup of G whose factor group is n-capable. ...  Read More
