Electrical study of plasticized carboxy methylcellulose based solid polymer electrolyte

The electrical conductivity and thermal conductivity of carboxyl methylcellulose doped with oleic acid and plasticized with glycerol have been measured by the electrical impedance spectroscopy method in the temperature range of 303 – 393 K. The composition of glycerol was varied between 0 and 50 wt. % and the samples were prepared via solution casting technique. The highest ionic conductivity at room temperature,...

Strength improvement of a High Performance Fiber Reinforced Concrete (HPFRC) containing local raw materials

Improvement of mechanical strength of a High Performance Fiber Reinforced Concrete (HPFRC) containing local raw materials at a cheap rate was investigated in this present work. An experimental study was conducted on different concretes based on dune sand and reinforced by metallic fibers. The concretes studied are formulated based on a Portland Cement (PC), Dune Sand (DS), Dust of Electro-filter (DE), Metallic Fibers...

Comment on "Combined heat and mass transfer by mixed convection magnetohydrodynamic (MHD) flow along a porous plate with chemical reaction in presence of heat source" by Zueco, J. and Ahmed, S., 2010, [Appl. Math. Mech. -Engl. Ed. 31(10), pp. 1217-1230]

In this paper, we demonstrate that the previously reported effect of the transverse magnetic field on a steady mixed convective heat and mass transfer flow of an incompressible viscous fluid past an infinite vertical isothermal porous plate considering the induced magnetic field with viscous and magnetic dissipations of energy by Zueco and Ahmed (2010) [Appl. Math. Mech. -Engl. Ed. 31(10), pp. 1217-1230] has some major...
