Numerical studies have been performed to interpret the observed “shock overtaking magnetic cloud (MC)” event by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane. Results of an individual MC simulation show that the MC travels with a constant bulk flow speed. The MC is injected with very strong inherent magnetic field over that in the ambient flow and expands ra...
In this study, we show that beam model differences play an important role in the comparison of does calculated with various algorithms for lung cancer treatment planning. These differences may impact the accurate correlation of dose with clinical outcome. To accomplish this, we modified the beam model penumbral parameters in an equivalent path length (EPL) algorithm and subsequently compared th...
Background: Prediction of the absorbed dose in irradiated volume plays an important role in the outcome of radiotherapy. Application of small fields for radiotherapy of thorax makes the dose calculation process inaccurate due to the existence of electronic disequilibrium and intrinsic deficiencies in dose calculation algorithms. To study the lung absorbed dose in radiotherapy with smal...
in this study, the relationship between components of knowledge management on the basis of m. mc olrvy model and social capital has been studied, statistical population consisted of employees of ministry of energy, who were selected among employees of hamedan regional power and were 420 subjects. research tool is a questionnaire and spss statistical software is used for data analysis and struct...
Rheumatoid arthritis (RA) is a chronic inflammatory disease and its exact cause and pathophysiological process remain unclear. Fibroblast-like synoviocytes, macrophages and T lymphocytes are considered to be the major contributors in the pathophysiological process of RA; however, an increasing number of papers have drawn attention to the potential role of mast cells (MCs) in the process. In an ...
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...
Moisture content (MC) is one of the most important quality parameters of green coffee beans. Therefore, its fast and reliable measurement is necessary. This study evaluated the feasibility of near infrared (NIR) spectroscopy and chemometrics for rapid and non-destructive prediction of MC in intact green coffee beans of both Coffeaarabica (Arabica) and Coffeacanephora (Robusta) species. Diffuse ...
A series of advanced WO3-based photocatalysts including CuO/WO3, Pd/WO3, and Pt/WO3 were synthesized for the photocatalytic removal of microcystin-LR (MC-LR) under simulated solar light. In the present study, Pt/WO3 exhibited the best performance for the photocatalytic degradation of MC-LR. The MC-LR degradation can be described by pseudo-first-order kinetic model. Chloride ion (Cl-) with prope...
