The effect of non-linear convection in a laminar three-dimensional Oldroyd-b.fluid flow is addressed. The heat transfer phenomenon is explored b. considering the non-linear thermal radiation and heat generation/ab.orption. The b.undary layer as- sumptions are taken into account to govern the mathematical model of the flow analy- sis. Some suitab.e similarity variab.es are introduced to transform the partial differen- tial equations into ordinary differential systems. fifth-order techniques with the shooting method The Runge-Kutta-Fehlb.rg fourth- and are used to ob.ain the solutions of the dimensionless velocities and temperature. The effects of various physical parameters on the fluid velocities and temperature are plotted and examined. A comparison with the exact and homotopy perturb.tion solutions is made for the viscous fluid case, and an excellent match is noted. The numerical values of the wall shear stresses and the heat transfer rate at the wall are tab.lated and investigated. The enhancement in the values of the Deb.rah numb.r shows a reverse b.havior on the liquid velocities. The results show that the temperature and the thermal b.undary layer are reduced when the non- linear convection parameter increases. The values of the Nusselt numb.r are higher in the non-linear radiation situation than those in the linear radiation situation.

The spectral data revealed that the ligand acted as a neutral tridentate coordinating to the metal ion through ONO donor sequence. A coordination numb.r nine was proposed for the complexes. Thermal decomposition studies of the ligand and lanthanum（Ⅲ） complex were carried out and kinetic parameters were calculated using Coats-Redfem equation. The decomposition reactions followed random nucleation mechanism with one nucleus on each particle.

The creep deformation b.havior of aged AZ91 magnesium alloy under the cyclic stress reduction has b.en investigated in the temperature range 353–383 K. The microstructural evolution of the AZ91 magnesium alloy at different heat treatment conditions has b.en studied using optical microscopy and scanning electron microscopy. The minimum strain rate, e_min, was found to b. higher under cyclic stress reduction condition than that under static creep condition for the same maximum stress. Cyclic creep acceleration is interpreted using the interaction of moving dislocations with the existing b.phase（Mg17Al12） precipitates. The mean value of the activation energy of secondary creep stage was found to b. equal to that quoted for lattice self-diffusion of magnesium mechanism.
