همانطور که می دانیم در سال های اخیر در کشور عزیزمان ایران، طرحها و پروژه های بسیار بزرگی در کلیه سطوح کشوری به اجرا درآمده است. که از آن جمله می توان به پروژه های بزرگ صنعت نفت، گاز و پتروشیمی اشاره نمود. با توجه به این واقعیت که اقتصاد ایران وابستگی شدید و بیمارگونه ای به درآمد های نفتی دارد استفاده از روش های نوین ابداع شده در خصوص تجارت الکترونیک به منظور به هدر نرفتن سرمایه گذاری ها و فرصت...
In this study, distribution of dose rate around the nuclear gauge device MC-1DR which located in shahrekord university was simulated by MCNPX code and was compared whit the measured values. Due to the asymmetry of device and neutron and gamma source positions, the dose rates were determined at a distance of 5, 30 and 100 cm in different directions. Base on the complex geometry of the inside of ...
Background and Objective: The aim of this study was to assess the sensitivity and uncertainty analysis of a mass balance model to estimate the rate of aerobic processes in a landfill. Materials and Methods: Monte Carlo simulation is a common method to evaluate uncertainty of the results of a model. Here, we used a Monte Carlo (MC) simulation. The data obtained from the experiments were used as...

PURPOSE Through the Monte Carlo (MC) simulation of 6 and 10 MV flattening-filter-free (FFF) beams from Varian TrueBeam accelerator, this study aims to find the best incident electron distribution for further studying the small field characteristics of these beams. METHODS By incorporating the training materials of Varian on the geometry and material parameters of TrueBeam Linac head, the 6 an...
This article investigates multicarrier (MC) transmission for next-generation global positioning system (GPS) instead of current spread spectrum signals. A MC code is proposed in this article as an alternative to the coarse/acquisition (C/A) code in GPS. The entire GPS bandwidth for the C/A code is divided into 1,024 subcarrier slots. As per our proposed arrangement, each satellite vehicle (SV) ...
Glutathione (GSH) conjugation was an important pathway to regulate the toxicity of microcystins (MCs) targeted to protein phosphatases. To explore the specific molecular mechanism for GSH detoxification, two typical MC-GSHs (derived from MCLR and MCRR) were synthesized, prepared, and purified according to previous research. Then, the reduced inhibition effect for MC-GSHs on protein phosphatase ...
Context. Recently, much attention has been paid to the magnetic coupling (MC) process, which is supported by very high emissivity indexes observed in Seyfert 1 galaxy MCG-6-30-15 and GBHC XTE J1650-500. But the rotational energy transferred from a black hole is simply assumed to be radiated away from the surrounding accretion disk in black-body spectrum, which is obviously not consistent with t...
