The relationship between trade liberalisation and the environment has been the subject of a growing body of literature in recent years. As can be seen from the differing assessment of instrument types for environmental protection, one of the important factors for the relationship between environmental protection and economic competitiveness are regulatory stringency and efficiency. This concern...

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...

background: the effects of the vascular endothelial growth factor (vegf) gene ?2578c/a polymorphism on colorectal cancer (crc) risk have been investigated in some studies; however, the results of these studies were conflicting and ambiguous. therefore, we aimed to do a meta-analysis to investigate the association of vegf ?2578c/a polymorphisms with crc risk from all eligible case-control studie...

the  non-classical mhc  class-i mainly involves in the  regulation of  innate  immune responses where hla-e  plays a significant role in the cell identification by natural killer cells. hla-e is a main regulatory ligand for natural killer cells and given the importance of these effector cells in hematopoietic stem cell transplantation, we investigated the effect of hla-e polymorphisms on post-h...

  The aim of this study was to determine the prevalence and clinical characteristics associated with stress Hyperglycemia among patients attending to the neonatal and pediatric Emergency wards. Patients who require d blood sampling for evaluated of an acute illness from August 1995 to July 1996 to the Namazi hospital of Shiraz medical university were enrolled prospectively for Hyperglycemia ( ...

The present study intended to evaluate EFL students' performance on a traditional method of writing assessment in comparison to an alternative assessment technique by taking into account the effects of teacher and peer feedback. Moreover, the attitudes of the participants regarding assessment procedures and activities were focused in this study. To this end, thirty male and female language lear...

The aim of this report is to make a review on DNA computing: molecular biology is used to suggest a new way of solving a NP-complete problem. The idea (due to Leonard Adleman in Adl94]) is to use strands of DNA to encode the (instance of the) problem, and to manipulate them using techniques commonly available in any molecular biology laboratory, in order to simulate operations that select the s...
