a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
سینتیک تخریب حرارتی خانواده ای ازپلیمرهای گرما سخت (پلی آمیدها) با استفاده از تکنیک tga ، در سه سرعت گرمادهی (0c min-1 20 و15 ،5/7) در اتمسفر نیتروژن بررسی شده است. روش های isoconversional (model – free) )از قبیل روش های فلاین، وال و ازاوا (fwo)، کیسینجر، آکاهیرا و سانوز(kas) و تانگ (tang) (و model – fitting (روش کوتس و ردفرن ((cr)استفاده شده اند تا سه تایی سینتیکی یعنی انرژی فعالسازی، فاکتو...
در این پژوهش نانو ذرات هیبریدی نانو لوله کربنی- اکسید روی سنتز و شناسایی شده¬است و نتایج آنالیز دستگاهی tem, sem و ft-ir تشکیل نانو ذره هیبریدی را تایید می¬نماید. اثر هیبرید سازی نانو لوله کربنی با اکسید¬ روی سرعت تخریب حرارتی یک ترموست بر پایه dgeba مورد بررسی قرار گرفت. مطالعات مقایسه¬ای نشان داد که سرعت تخریب با هیبرید سازی نانو ذرات کاهش می¬یابد و از روش زیر تبعیت می¬کند. rpure dgeba > r m...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
Hypoxic-ischaemic encephalopathy (HIE) in a full-term infant is a clinically defined syndrome of the disturbed neurologic function in the earliest days after birth in infancy, manifested by difficulty with initiating and maintaining respiration, the depression of the muscle tone and reflexes, the subnormal level of consciousness and often seizures (Nelson & Leviton, 1991). HIE is the term used ...
This paper describes a method of estimating the nucleotides in red blood cells. The technique used is based on that of Cohn and Carter (1950), who have shown that the nucleotides, adenosinemonophosphate (A.M.P.), adenosinediphosphate (A.D.P.), and adenosinetriphosphate (A.T.P.) can be separated by an anion exchange column. Bartlett, Savage, Hughes, and Marlow (1953) have successfully used this ...

Introduction: Negative emotions can have destructive effects on the treatment and recovery process of breast cancer patients. The present study aims to investigate relationships between emotional processing deficits with post-traumatic stress symptoms, and adherence to treatment in patient with breast cancer with the mediating role of cancer stigma. Methods: in terms of the purpose, the presen...
Water Adsorption on Aggregates of Spherical Aerosol Nano Particles. (August 2005) Chu Nie, B.S., Nanjing University Chair of Advisory Committee: Dr. William H. Marlow A three dimensional integral equation is developed in order to compute water adsorption onto aggregates of spherical aerosol nano particles. The integral equation is derived from molecular density functional theory, with a weighte...
