Leading order perturbative QCD predictions are given for the twophoton processes yy + ~71, 6, and pp at large momentum transfer. As we have shown in a series of recent papers,l the predictions of perturbative quantum chromodynamics can be extended to the whole domain of large momentum transfer exclusive processes. The results lead to a comprehensive new range of rigorous predictions of QCD whic...

in this paper, free convection in an inclined stepped chamber has been studied. one wall of this enclosure is kept cold and the opposite wall equipped with constant heat source. the remaining walls are maintained adiabatic. there is one adiabatic step on the bottom wall. the aim of the present study is to forecast the effect of raleigh number, slope of enclosure, step dimension, and heat source...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...
