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...

Lhermitte - Duclos disease also called dysplastic gangliocytoma of cerebellum is an extremely rare cerebellar lesion which share features of both malformation and neoplasm. The usual presentation is of raised intracranial pressure along with cerebellar signs. We report a case of 23 year male who presented with headache & diplopia. MRI was suggestive of the diagnosis. Subtotal excision of th...

• The ejection of blood into the root of the aorta by the heart produces pressure changes which are transmitted peripherally through the vascular bed. The propagation of these pressure waves has been a topic of interest and conjecture for a number of years because of its importance in the study of the physical properties and energetics of the vascular bed. As a result many data have accumulated...

the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...

gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. it also has significant impact on heat transfer. both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. an arrangement for obtaining a stratified charge, using port injection, is proposed for a cur...

In this paper, hydroforming process of bent tubes in T-shaped die is studied for pulsating and linear pressure paths by the finite element method. Forming Limit Diagrams (FLDs) and thickness distribution curves are used to investigate the effect of pulsating pressure on hydroforming process. In addition, the obtained numerical results are compared with experimental results of hydroforming of st...
