رها شدن گاز so2 در اثر احتراق سوخت های فسیلی یکی از علل اصلی آلودگی زیست محیطی و بیماری های تنفسی می باشد. عمده ترین ماده گوگردی موجود در نفت خام و برش های آن به صورت دی بنزوتیوفن و مشتقات الکیله آن می باشد. در گوگردزدایی زیستی، حذف گوگرد از برش های نفتی با استفاده از باکتری ها توسط محصولات ژن هایabc dsz که اولین بار از باکتریrhodococcus erythropolis strain igts8 جدا شدند از طریق مسیرمتابولیکی ...

  In this paper, the uniaxial strain effect on the electronic properties of (6,6) finite armchair carbon nanotube was investigated by using the Green function technique and Landure-Buttiker formula. It was found that, in (6,6) finite carbon nanotube with 3q and 3q+1 length, where q is a certain integer, the current was induced by the application of a suitable tensile strain and compressive stra...

The plastic behavior of materials depends on their strain rate sensitivity. The main objective of this paper is the analysis of the effect of strain rate sensitivity on plastic behavior of cylindrical shells under internal pressure loading and hence a large number empirical tests have been conducted on aluminum cylindrical shells. We have also manufactured and used a hydrostatic test machine to...

Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...
