1. Enhanced Expression of Recombinant Activin A in Escherichia coli by Optimization of Induction Parameters

Z. Hajihassan; N. Biroonro

Volume 29, Issue 2 , Spring 2018, Pages 105-111

http://dx.doi.org/10.22059/jsciences.2018.65016

Abstract
  Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli ...  Read More

4. Petrography, Major and Trace Elemental Geochemistry of the Ordovician-Silurian Siliciclastics in North of Tabas Block, Central Iran: Implications for Provenance and Paleogeography

E. Khazaei; M.H. Mahmoudy-Gharaie; A. Mahboubi; R. Moussavi-Harami; J. Taheri

Volume 29, Issue 2 , Spring 2018, Pages 129-142

http://dx.doi.org/10.22059/jsciences.2018.65019

Abstract
  The upper part of Shirgesht (UPS) and lower part of Niur (LPN) formations (Ordovician-Silurian) consist of sandstone, shale and limestone, respectively. The petrography and geochemical analysis conducted to evaluate provenance of siliciclastic deposits in order to understand the paleogeography of Central ...  Read More

5. Estimation of Plunge Value in Single- or Multi-Layered Anisotropic Media Using Analysis of Fast Polarization Direction of Shear Waves

K. Latifi; A. Sadidkhouy; M. R. Ghassemi

Volume 29, Issue 2 , Spring 2018, Pages 143-156

http://dx.doi.org/10.22059/jsciences.2018.65020

Abstract
  Estimation of the fast polarization direction of shear seismic waves that deviate from horizontal axis is a valuable approach to investigate the characteristics of the lower crust and uppermost mantle structures. The lattice preferred orientation of crystals, which is generally parallel to the downward ...  Read More

Abstract
  In this research, petrographic and geochemical (major and trace elements) characteristics of siliciclastic rocks of the Mozduran Formation in the eastern Kopet-Dagh Basin have been carried out in order to reveal their provenance such as source area paleoweathering, parent rock composition and tectonic ...  Read More

7. Bayesian Inference for Spatial Beta Generalized Linear Mixed Models

L. Kalhori Nadrabadi; M. Mohhamadzadeh

Volume 29, Issue 2 , Spring 2018, Pages 173-185

http://dx.doi.org/10.22059/jsciences.2018.65022

Abstract
  In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model has been introduced to analyze such observations. ...  Read More
