The main objective of this paper is to numerically investigate the results of a mathematical model for unsteady magnetohydrodynamics (MHD) boundary layer flow over a porous stretching surface. The analysis of non-Newtonian Maxwell nanofluid is presented involving the influence of porous media, thermal radiation, viscous dissipation, and joule heating through the Keller box method. Partial slip and convective conditions are also enacted near the boundary. After using the similarity technique on the governing system of nonlinear partial differential equations, the Keller box method is then implemented to find out the numerical solution for copper-water Cu-H 2 O and molybdenum disulfide MoS 2 -H 2 O nanofluids. The impact of various governing flow parameters is interpreted numerically and illustrated graphically on the interaction of particles. Additionally, numerical results are further utilized to calculate the skin friction coefficient and heat transfer rate at the boundary. Finally, in a limiting case, the acquired numerical results are compared with existing results. The remarkable finding of the present study is that Cu-H 2 O based nanofluid is detected as a superior thermal conductor instead of MoS 2 -H 2 O based nanofluid.

The lending and asset price transmission channels remain largely unexplored since financial reforms and pursuance of market-based monetary policy instruments. This paper examines the monetary policy transmission mechanisms of Pakistan with a special focus on bank lending and asset price channels. Monthly data over the period 2000M7-2016M12 is being used for the short run analysis. The empirical investigation is based on SVAR framework. The results show that the monetary aggregates targeting agenda is still operative in effecting the output and general price level. Bank lending have a non-trivial part through the investment channel and share prices through wealth effect on price level and output, while the conventional interest rate channel seemed to be ineffective in the transmission mechanism process in Pakistan. The findings of generalized impulse response functions are backed by the generalized error forecast variance decomposition analysis. In addition to domestic variables, external shocks appear to have a strong influence on inflation and output in Pakistan.Contribution/ Originality: This study contributes in the existing literature by examining the monetary policy transmission mechanisms of Pakistan with a special focus on bank lending and asset price channels.
