This paper presents simulation studies on the recovery of Acetonitrile from aqueous waste pharmaceutical processes. The focus is atmospheric distillation in two sequential columns to understand separation feasibility system; first column produces a distillate azeotropic composition, which mixed with fresh stream and fed second column, 99.9% pure residue. effect reflux ratio, reboiler duty flowr...

Ordinary differential equations(ODEs) with stochastic processes in their vector field, have lots of applications in science and engineering. The main purpose of this article is to investigate the numerical methods for ODEs with Wiener and Compound Poisson processes in more than one dimension. Ordinary differential equations with Ito diffusion which is a solution of an Ito stochastic differentia...

The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...

In the current study, the kinetics of asphaltene particle flocculation is investigated under a shear flow through numerical simulation. The discrete element method (DEM) is coupled with computational fluid dynamics (CFD) to model the agglomeration and fragmentation processes. In addition, a coalescence model is proposed to consider the attachment of colliding particles. The changes in mean asph...

two physicians, both grown up in west europe, educated also in this area (supplemented by many visits of the united states), travelled 20 years ago to japan for scientific reasons and they changed thereafter in their mental sight of the world. in a first part, the neurophysiologic basis of sensation from the sensory receptor up to the cerebral cortex (“bottom up”), the mechanisms of building me...

background alcoholic hepatitis (ah) is an acute manifestation of alcoholic liver disease with high mortality rates. objectives our aim was to study the molecular mechanisms of ah. materials and methods the differentially expressed genes (degs) in liver between ah and control cases were identified by analyzing the gse28619 microarray data using t-test. the kyoto encyclopedia of genes and genomes...
