This framework presents heat transfer analysis for swirling flow of viscoplastic fluid bounded by a permeable rotating disk. Problem formulation is made through constitutive relations of Bingham fluid model. Viscous dissipation effects are preserved in the mathematical model. Entropy production analysis is made which is yet to be explored for the von-Kármán flow of non-Newtonian fluids. Having found the similarity equations, these have been dealt numerically for broad parameter values. The solutions are remarkably influenced by wall suction parameter and Bingham number which measures the fluid yield stress. Akin to earlier numerical results, thermal boundary layer suppresses upon increasing wall suction velocity. Thermal penetration depth is much enhanced when fluid yield stress becomes large. Higher heat transfer rate can be accomplished by employing higher suction velocity at the disk. However, deterioration in heat transfer is anticipated as fluid yield stress enlarges. Current numerical results are in perfect line with those of an existing article in limiting sense.

Over the last three decades, there have been high inflows of FDI at unprecedented accelerated rates; but the growth of exports has been increasing, however, not at satisfactory level. FDI can affect, directly and indirectly, the exports of hosting country. Using the time series data from 1977 to 2005, a double log model has been used to estimate impact of FDI on exports and results show that the two years lagged FDI has statistical significant positive impact on the current exports of Pakistan. FDI in textile sector, which is backbone of exports, had been very low in this period. The same was the case with other exporting sectors. As a matter of fact, exports do have a significant place in Pakistan, so Government of Pakistan should formulate such economic policies, as relaxation on foreign exchange control, abolishment of technical fee and introduction of the suitable tax relief policy for the foreign investors that attract FDI, especially resource-oriented, in Pakistan.
