Micropolar fluid behavior on MHD heat transfer flow through a porous medium with induced magnetic field by finite difference method

Sultana, M.*; Haque, M. M.*; Alam, M. M.*; Ferdows, M.; Postelnicu, A.*

European Journal of Scientific Research, 53(3), p.477 - 490, 2011/05

A unsteady MHD heat transfer by free convective micropolar fluid flow through an infinite vertical porous medium under the action of strong magnetic field have been studied numerically with induced magnetic field. This investigation is performed for the turbulent boundary layer cooling problem with constant suction velocity. The unconditionally stable implicit finite difference technique is used to solve the non-dimensional momentum, angular momentum, magnetic induction and energy equations. The computed values of fluid velocity, angular velocity, induced magnetic field and temperature distributions as well as the steady-state wall shear stress, wall couple stress, current density and Nusselt number are shown graphically. Finally, the important findings are listed here.

MHD free convective heat generating unsteady micropolar fluid flow through a porous medium with constant heat and mass fluxes

Haque, M. M.*; Alam, M. M.*; Ferdows, M.; Postelnicu, A.*

European Journal of Scientific Research, 53(3), p.491 - 515, 2011/05

Unsteady MHD heat and mass transfer by free convective micropolar fluid flow over an infinite vertical porous medium under the action of transverse magnetic field with thermal diffusion have been studied numerically in the presence of constant heat source. This investigation is performed for both cooling and heating problem with constant suction velocity when the medium is subjected to constant heat and mass fluxes. A finite difference technique with stability and convergence analysis is used to solve the non-dimensional momentum, angular momentum, energy and concentration equations. The computed values of fluid velocity, angular velocity, temperature and concentration distributions, wall shear stress, wall couple stress, Nusselt number and Sherwood number are shown graphically. Finally, a qualitative comparison with previous work is tabulated.

Tuning hydrogen production during oxide irradiation through surface grafting

Alam, M.*; Miserque, F.*; Taguchi, Mitsumasa; Boulanger, L.*; Renault, J. P.*

Journal of Materials Chemistry, 19(24), p.4261 - 4267, 2009/06

The production of molecular hydrogen in the radiolysis with TiO$$_{2}$$ grafted silica has been carefully studied using 10 MeV electrons. In all cases, H$$_{2}$$ yield increases linearly with absorbed dose. Under the irradiation it was observed that with the increasing number of titanium dioxide deposition cycle a decrease in dihydrogen production were observed. A faster decrease in dihydrogen production was observed with a very small amount of titanium dioxide deposition i.e with an average thickness of 0.1 nm as measured by XPS. The productions of H$$_{2}$$ were found to be decreased almost by 50 % with a TiO$$_{2}$$ thickness at around 1 nm.

Since ionizing radiation is used for sterilizing or lowering the microbial content of foods, the development of versatile detection methods of irradiated foods is necessary for appropriate management. In an effort to distinguish between irradiated and non-irradiated food, a method based on the detection of oxidative DNA base damage using the chemiluminescence enzyme-linked immunosorbent assay (ELISA) with anti-8-hydroxy-2'-deoxyguanosine antibody was developed. It was shown that this chemiluminescence ELISA method could be applied to chicken, beef and pork that were irradiated with over 3 kGy. Twenty milligrams of a loaf of meat was sufficient to distinguish between irradiated and non-irradiated meat by this method.

Detection of oxidative DNA damage using Anti-8-OHdG Antibody; A Useful method to distinguish irradiated foods

Kikuchi, Masahiro; Mohd Dzomir, A. Z.; Gunawardane, C. R.; Alam, M. K.; Kobayashi, Yasuhiko

JAEA-Review 2006-042, JAEA Takasaki Annual Report 2005, P. 72, 2007/02

Ionizing radiation has been used for reducing food losses and securing food safety. The development of versatile detection methods of irradiated foods is needed for appropriate management. In an effort to distinguish between irradiated and non-irradiated meats, a detection method of oxidative DNA base damages using chemiluminescence enzyme-linked immunosorbent assay with anti-8-hydroxy-2'-deoxyguanosine antibody was developed. The procedure of this method is not so complicated, and relatively short time is needed to obtain results without special techniques. For most of all foods containing DNA, this novel method should be applicable to detect the damaged DNA of irradiated foods. Application to beef meat irradiated with 3 kGy or higher was suggested to be detectable successfully.
