in the 21st century, distinctions and boundaries between global health, international politics, and the broader interests of the global community are harder to define and enforce than ever before. as a result, global health workers, leaders, and institutions face pressing questions around the nature and extent of their involvement with non-health endeavors, including international conflict reso...

the purpos of this paper is to aim the maximum heat transfer rate in a plate-fin heat exchanger with a constant volume and a contant surface area at a prescribed pressure drop. this paper propose a method for design a plat-fin heat exchanger in which a maximum pressure drop occurs at a constant volume and surface are. in this paper as a case study, a preheater of a gas turbine which is a plate-...

Barium substituted nanocrystalline ferrites with chemical composition BaxCa1-xFe2O4 (x =0.0 to 0.25) BCAF were prepared by solution combustion method. The phase formation of mixed spinal structured ferrites was confirmed by PXRD analysis. The average crystallite size was calculated using Debye-Scherrer formula and it was found to be in the range of 27-44 nm. Surface morphology was analyzed by S...

This paper proposes a James-Stein-type (JS) adjustment to analytical bias correction in fixed effects panel models that suffer from the incidental parameters problem. We provide high-level conditions under which infeasible JS leads higher-order MSE improvement over bias-corrected estimator, and former is asymptotically equivalent latter. To obtain feasible adjustment, we propose nonparametric b...
