در تحقیق حاضر با هدف حذف آلاینده های پاراتولوئن سولفونیک اسید (p-tsa) و پاراتولوئیک اسید (p-ta) از محیط آبی، در ابتدا جاذب پلی استایرن توسط سه گروه عاملی مختلف (مونواتانول آمین، دی اتانول آمین و تری اتانول آمین) عامل دار شد. پس از آن مناسبترین شرایط برای تولید جاذب از نظر نوع و میزان گروه های عاملی تعیین گردید. بر این اساس، عامل دار کردن جاذب پلیمری توسط دی اتانول آمین و با بیشینه ی دانسیته ی گ...

A double Dudeney set in Kn is a multiset of Hamilton cycles in Kn having the property that each 2-path in Kn lies in exactly two of the cycles. In this paper, we construct a double Dudeney set in Kn when n = p1p2 · · · ps + 2, where p1, p2, . . . , ps are different odd prime numbers and s is a natural number.

We investigate in this paper the performance of a simple file sharing principle. For this purpose, we consider a system composed of N peers becoming active at exponential random times; the system is initiated with only one server offering the desired file and the other peers after becoming active try to download it. Once the file has been downloaded by a peer, this one immediately becomes a ser...

The study was conducted to know the rate of maternally derived antibodies (MDAs) transfer from parents to their offspring and declining the MDAs in their chicks at 0, 7, 14, and 21 days of age against four major poultry viruses like Newcastle disease virus (NDV), Infectious bronchitis virus (IBV), Infectious bursal diseases virus (IBDV), and Avian Reo virus (ARV). The MDAs was studied on Grandp...

In this research, firstly polyaniline-zinc oxide (PANI-ZnO) nanocomposite was successfully synthesized by chemical polymerization of aniline in the presence of ZnO nanoparticles and then, 5%, 10% and 15% solutions of PANI–ZnO nanocomposites were mixed with a solution of polystyrene (PS) in tetrahydrofurane (THF) and PANI-PS-ZnO nanocomposites were obtained. The prepared nanocomposites were used...
