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...

the functional response of a predator is the base of prey-predator dynamics. functional response of serangium montazerii fã¼rsch at different egg densities (50, 100, 150, 200 and 250) of dialeurodes citri (ashmead) was studied in an open-patch experiment, in a growth chamber (25 â± 1â°c, 65 â± 5% rh and a photoperiod of 16: 8 l: d h) on ‘thompson’ navel orange (citrus sinensis cv. thompson)...

T he objective of this study is using the Markov Switching Vector Autoregressive method and regime dependent impulse response functions to measure the pass-through of world food prices to consumer price index in Iran from 1990 to 2013. With respect to information criteria and the log-likelihood ratio statistic, MSIA(2)-VAR(1) model has a better fit to data than other models. The magn...
