Research ArticleOpen accessIn the abstractOn a Problem Connected with Navier-stokes Equations in Non Cylindrical DomainsJ. Limaco, S. B. de Menezes, C. Vaz, J. F. MontenegroIn this study we showed the existence of weak solutions of equations that represent flows of a non-homogeneous viscous incompressible fluids in a non cylindrical domain in R3 . The classical Navier-stokes equation is a particular case of the equations here considered. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,610 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInformation Provided by Accrual and Cash Flow Measures in Determining Firms’ Performance: Malaysian EvidenceNorita Mohd Nasir, Shamsul Nahar AbdullahAccrual and cash flow measures have been argued to be able to evaluate firms’ performance, although the results are inconclusive throughout countries and time. This study examined the accrual and cash flow measures independently and jointly among Malaysian firms. The study predicted that the low cash flow subgroups (high income to cash flow firms) would show better results in operating, … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 7,327 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Simulation Study of Enhanced Distillation Using Ultrasound Waves for the Separation of Azeotropic MixturesTaha Mahdi, Ammar Emad Al-KawazThe potential of ultrasound waves to enhance distillation system for azeotropic mixture is examined through process flowsheeting using Aspen Plus. Since sonication is not a standard feature in the software library, a mathematical model of the proposed distillation system is developed based on first principles in Aspen Custom Modeler and later exported to Aspen Plus environment for process simulation and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Jan 2018 · 8,411 accessesView PDF Cite
