Title: Jordan Left Derivations of Two Torsion Free ГM – Modules
Authors: Paul, A C; Halder, Amitabh Kumer
Abstract: Let M be a Г-ring and X be a 2-torsionfree left ГM-module. The purpose of this
paper is to investigate Jordan left derivations on M considering aαbβc=aβbαc, for
every a,b,c∈M and α,β∈Г . We show that the existence of a nonzero Jordan left
derivation of M into X implies M is commutative. We also show that if X = M is a
semiprime Г-ring, then the derivation is a mapping from M into its centre. Finally
we show that if M is a prime Г- ring, then every Jordan left derivation d: M→ M is a
left derivation.

Title: Multiobjective Nonlinear Programming Problems Involving Second Order (b,F)-Type I Functions
Authors: Pandian, P; Natarajan, G
Abstract: A new class of functions namely, second order (b,F) -type I functions which is
the generalization of type I, F-type I and b-type I functions, is introduced.
Sufficient optimality conditions for proper efficiency and second order mixed type
duality theorems for multiobjective nonlinear programming problems are
established under the assumptions of second order (b,F) -type I functions.

Title: MHD Natural Convection Flow of Viscous Incompressible Fluid From a Vertical Flat Plate
Authors: Ahmmed, S F; Sarker, M. S. Alam
Abstract: A two-dimensional natural convection flow of a viscous incompressible and
electrically conducting fluid past a vertical impermeable flat plate is considered in
presence of a uniform transverse magnetic field. The governing equations are
reduced to ordinary differential equations by introducing appropriate coordinate
transformations. We solve that ordinary differential equations and find the velocity
profiles, temperature profile, the skin friction and nusselt number. The effects of
Grashof number (Gr), Hartmann number(M) and Prandtl number(Pr) on velocity
profiles and temperature profiles are shown graphically.
