 در این مقاله، نانوذرات γ-آلومینای آغشته به جیوه با روش آغشته‌سازی نانوذرات γ-آلومینا با جیوه استات در محلول آب و ایزوپروپانول و به دنبال آن آبکافت، شستشو، صاف و خشک‌کردن در دمای اتاق، تهیه شدند. ساختار این نانوذرات با الگوی پراش پرتو ایکس (XRD) تأیید شد. از الگوی XRD برای تأیید پیوند بین نانوذرات آغشته به جیوه و باز آلی تیمین در DNA سلول هدف نیز استفاده شد. اثرات زیستی و سمی نانوذرات γ-آلومینا...

We investigate the homology of a congruence subgroup Γ SL3(Z) with coefficients in Steinberg modules St(Q3) and St(E3), where E is real quadratic field are Q. By Borel-Serre duality, H0(Γ,St(Q3)) isomorphic to H3(Γ,Q). Taking image connecting homomorphism H1(Γ,St(E3)/St(Q3))→H0(Γ,St(Q3)), followed by isomorphism, we obtain naturally defined Hecke-stable subspace H(Γ,E) conjecture that independe...

This paper reports results of a study regarding the activities of nano structure Mn/γ-Al2O3 and γ-Al2O3 catalysts for oxidation of 2-propanol (as a model of volatile organic compound). Nanostructure of catalysts was revealed using XRD, SEM and TEM techniques. Catalytic studies were carried out in U-shaped packed bed reactor under atmospheric pressure and at the reaction temperature of 150- 500°...

introduction relative dose computation is a necessary step in radiation treatment planning. therefore, finding an approach that is both fast and accurate seems to be necessary. the purpose of this work was to investigate the feasibility of natural cubic spline to reconstruct dose maps for linear accelerator radiation treatment fields in comparison with those of the simulation. materials and met...

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...
