Stability of Granular Materials under Vertical Vibrations
(2003-01)
The influence of periodic vibrations on the granular flow of materials is of great interests to scientists and engineers due to both theoretical and practical reasons. In this paper, the stability of a vertically vibrated ...
Bubble Behavior in a Taylor Vortex
(2005-01)
We present an experimental study on the behavior of bubbles captured in a Taylor vortex. The gap between a rotating inner cylinder and a stationary outer cylinder is filled with a Newtonian mineral oil. Beyond a critical ...
On the Electrostatics of Pneumatic Conveying of Granular Materials
(2004-01)
In this work the electrostatics of the pneumatic conveying of granular materials in a non-conducting (PVC) vertical pipe is studied using Electrical Capacitance Tomography (ECT) system. The non-conducting wall in general ...
Particle Image Velocimetry Study on the Stripe Formation in Vertically Vibrated Granules
(2004-01)
Recently, granules under vertical vibrations receive many attentions due to their importance in theoretical research and engineering application. In this paper, a two-dimensional Particle Image Velocimetry (PIV) system was ...
Fabrication of Controlled Release Devices Using Supercritical Antisolvent Method
(2005-01)
In this study, the supercritical antisolvent with enhanced mass transfer method (SASEM) is used to fabricate micro and nanoparticles of biocompatible and biodegradable polymer PLGA (poly DL lactide co glycolic acid). This ...
Subcutaneous study on the controlled release of Etanidazole and Taxol for the treatment of Glioma
(2005-01)
BALB/c nude mice 6 weeks old were inoculated with glioma C6 cell-line and the efficacy of the different amount of Etanidazole-discs and Taxol-microspheres was investigated. Poly (D,L-lactic-co-glycolic acid) (PLGA) was ...
Granular Attrition due to Rotary Valve in a Pneumatic Conveying System
(2005-01)
The rotary valve is a widely used mechanical device in many solids-handling industrial processes. However, it may also be responsible for most of the attrition effects occurring in a typical process. In this study, the ...
Study on Granular Dynamics in Vertically Vibrated Beds using Tracking Technique
(2005-01)
The study of granular material is of great interest to many researchers in both engineering and science communities. The importance of such a study derives from its complex rheological character and also its significant ...
Delivery of Etanidazole to Brain Tumor from PLGA Wafers
(2004-01)
This paper presents the computer simulation results on the delivery of Etanidazole (radiosensitiser) to the brain tumor and examines several factors affecting the delivery. The simulation consists of a 3D model of tumor ...
Fabrication of Micro and Nanoparticles of Paclitaxel-loaded Poly L Lactide for Controlled Release using Supercritical Antisolvent Method: Effects of Thermodynamics and Hydrodynamics
(2006-01)
This paper presents the fabrication of controlled release devices for anticancer drug paclitaxel using supercritical antisolvent method. The thermodynamic and hydrodynamic effects during supercritical antisolvent process ...
